Estado da Técnica State of the Art
002 Em termos de conceitos fundamentais de Truques Ferroviários, o transporte ferroviário permaneceu inerte no mínimo nos últimos 100 anos. O segmento ferroviário é tradicionalmente conservador quando se fala em novas tecnologias, além do fato de que poucas tecnologias realmente disruptivas em termos de conceitos fundamentais e de viabilidade surgiram nos últimos anos. E as que surgiram, são por vezes complexas e de elevado valor financeiro, o que muitas vezes inviabiliza a implementação das mesmas em larga escala. 002 In terms of fundamental concepts of Railway Tricks, railway transport has remained inert for at least the last 100 years. The railway segment is traditionally conservative when it comes to new technologies, in addition to the fact that few truly disruptive technologies in terms of fundamental concepts and viability have emerged in recent years. And those that have emerged are sometimes complex and have high financial value, which often makes their implementation on a large scale unfeasible.
003 Quando se fala em transporte ferroviário convencional (locomotivas e vagões], dentre os principais gastos, estão: combustível, rodeiros e manutenção / reforma das ferrovias. Os gastos de combustível são amplificados pelo elevado atrito do atual sistema de truques, cujas flanges das rodas estão em constante atrito com os boletos dos trilhos. Além de desgastar sobremaneira as rodas e os trilhos, este atrito também amplifica o consumo de combustível, sendo que se houvesse um sistema que diminuísse este atrito, seriam economizados rodeiros, trilhos e combustível. 004 Destaque-se também a questão da segurança contra descarrilamentos, pois os truques / Truques convencionais apresentam este 'ponto fraco', da suscetibilidade a acidentes de descarrilamento, pois a flange das rodas escala os boletos dos trilhos continuamente para o trânsito dos veículos. A conta anual de prejuízos materiais e humanos devido a descarrilamentos supera a casa das dezenas de bilhões de dólares no mundo, e é uma preocupação constante dos fabricantes e operadores ferroviários. 003 When talking about conventional railway transport (locomotives and wagons), among the main expenses are: fuel, wheelsets and maintenance / renovation of railways. Fuel costs are amplified by the high friction of the current bogie system, whose wheel flanges are in constant friction with the rail billets. In addition to putting excessive wear on the wheels and tracks, this friction also amplifies fuel consumption, and if there was a system that reduced this friction, wheelsets, tracks and fuel would be saved. 004 The issue of safety against derailments should also be highlighted, as conventional tricks/tricks present this 'weak point', of susceptibility to derailment accidents, as the wheel flange climbs the rail billets continuously for vehicle traffic. The annual bill for material and human losses due to derailments exceeds tens of billions of dollars worldwide, and is a constant concern for railway manufacturers and operators.
005 Os Truques tradicionais, são dotados de (3 peças], que possui 02 [dois] longeirões, um em cada lado e 01 [hum] travessa principal, o que impede a execução de curva em perfeita interação com a via, possui um atrito elevado, pouco estabilidade e segurança, o que resulta muitas vezes em graves acidentes. 005 The traditional Tricks are equipped with (3 pieces), which has 02 [two] long beams, one on each side and 01 [one] main beam, which prevents the execution of a curve in perfect interaction with the road, it has friction high levels, little stability and safety, which often results in serious accidents.

Na FIGURA 13 se visualiza no destaque a máquina de esterçamento (M) composta do rolete principal (22), que se apoia no trilho secundário (26), e este último se apoia na travessa do trilho secundário (15). A articulação rotular secundária (25) também é fixa na travessa do trilho secundário (15). Esta articulação rotular secundária (25), por sua vez, conectada à esfera rotular (23), se move relativamente radialmente à articulação rotular principal (24), que está por sua vez conectada à travessa do trilho de rolete principal (19). Apoiado no trilho de rolete principal (19) está o rolete secundário (20), que por sua vez está solidário à travessa do rolete secundário (9).

In FIGURE 13, the steering machine (M) is highlighted, consisting of the main roller (22), which rests on the secondary rail (26), and the latter rests on the cross member of the secondary rail (15). The secondary ball joint (25) is also fixed to the secondary rail cross member (15). This secondary patellar joint (25), in turn, connected to the patellar ball (23), moves relatively radially to the main patellar joint (24), which is in turn connected to the main roller rail crosshead (19).

Na FIGURA 15 tem-se a mesma situação da figura anterior, porém com uma curva sendo realizada para a esquerda. Percebe-se o ângulo 'C' desempenhado pelos eixos e longeirões, principal e secundário. In FIGURE 15 there is the same situation as the previous figure, but with a curve being made to the left. The 'C' angle played by the main and secondary axes and beams can be seen.
Na FIGURA 16 verifica-se no detalhe os sistemas de roletes e articulação rotular. Com a inserção do Truque em uma curva, ocorre o movimento relativo angular dos roletes primário [22], secundário [20] sobre os trilhos de rolete primário [26] e secundário [19], respectivamente. Solidário às estruturas dos roletes tem-se as articulações rotulares principal [24] e secundária [25], que pivotam radialmente na esfera rotular [23]. A articulação rotular de estabilização é composta pelas articulações rotulares principal [24] e secundária [25] e pela esfera rotular [23]. Este sistema tem a função de manter os conjuntos primário e secundário girando relativamente em perfeita trajetória circula, bem como promove o travamento vertical do Truque. Por sua característica de 'rótula universal', este permite a torção do Truque, mantendo a estabilidade em condições adversas de relevo do trilho. Na FIGURA 17 constata-se uma visão geral em perspectiva do invento objeto Truque ferroviário radial esterçante, onde se verificam os eixos principal [12] e secundário [17], longeirões principal [8] e secundário [13], as rodas, divididas e independentes entre banda de rodagem [5] e flange livre (6), a máquina de esterçamento [18], a travessa principal [33] e o pacote de molas [34].

When the Trick is inserted into a curve, there is a relative angular movement of the primary [22], secondary [20] rollers on the primary [26] and secondary [19] roller tracks, respectively. Solidarity with the roller structures are the main [24] and secondary [25] roller joints, which pivot radially on the roller sphere [23]. The stabilizing patellar joint is composed of the main [24] and secondary [25] patellar joints and the patellar ball [23]. This system has the function of keeping the primary and secondary assemblies rotating relatively in perfect circular trajectory, as well as promoting the vertical locking of the Trick. Due to its 'universal ball joint' feature, it allows the Trick to twist, maintaining stability in adverse conditions of the trail's terrain. In FIGURE 17 there is an overview in perspective of the invention object Steering radial railway trick, where the main [12] and secondary [17] axles, main [8] and secondary [13] long axis, the wheels, divided and independent between tread [5] and free flange (6), the steering machine [18], the main cross member [33] and the spring package [34].
Na FIGURA 18 (A) tem-se vista superior do invento objeto Truque ferroviário radial esterçante onde se pode visualizar o prato do pião (37), o ampara balanço [36], a travessa do rolete secundário [15], a travessa do trilho secundário (9), a travessa do trilho de rolete principal [14], o sistema de rolamento da banda de rodagem [34], a roda da banda de rodagem (5), o sistema de rolamento da roda do flange livre (35), a roda do flange livre (6), o longeirão principal [8] e o longeirão secundário (13).

Na FIGURA 18 (B) tem-se uma vista lateral do invento objeto Truque ferroviário radial esterçante, com destaque para os perfis laterais do longeirão principal (8) e do longeirão secundário (13). In FIGURE 18 (B) there is a side view of the invention object Steering radial rail trick, highlighting the side profiles of the main beam (8) and the secondary beam (13).

In FIGURE 19 (A) you can see a front view of the invention object Steering radial railway trick, where you can see the tread bearing system (34), the tread wheel (5), the wheel bearing system free flange wheel (35), the free flange wheel (6) and the main shaft (12).
Na FIGURA 19 (B) confere-se novamente a roda da banda de rodagem (5), e a roda do flange livre (6), esquematicamente sobre trilhos (7). Nos detalhes (B) e (C) tem-se no destaque as rodas da banda de rodagem (5), e a roda da flange livre (6). Um dos objetos do presente invento consiste justamente nesta roda ferroviária 'bipartida', onde a roda e o flange giram de forma independente. Na maior parte do tempo somente a roda da banda de rodagem [5] permanece em contato com o trilho. Somente em curvas é que a roda do flange livre [6] entrará em contato com o boleto do trilho. Por suas características de projeto, o sistema de roda livre e flange livre, que giram de forma completamente independente, o presente invento objeto Truque ferroviário radial esterçante apresenta resistência ao arrasto e atrito significativamente inferiores quando comparado com um Truque convencional. Ademais, também apresenta maior estabilidade, e impede a ocorrência de descarrilamentos na maior parte das situações, traduzindo em expressiva maior segurança em termos de descarrilamento quando comparado a um Truque convencional. In FIGURE 19 (B) the tread wheel (5) and the free flange wheel (6) can be seen again, schematically on rails (7). In details (B) and (C) the tread wheels (5) and the free flange wheel (6) are highlighted. One of the objects of the present invention consists precisely of this 'split' railway wheel, where the wheel and the flange rotate independently. Most of the time only the band wheel tread [5] remains in contact with the rail. Only when cornering will the free flange wheel [6] come into contact with the rail billet. Due to its design characteristics, the free wheel and free flange system, which rotate completely independently, the present invention subject to a steering radial rail truck presents significantly lower resistance to drag and friction when compared to a conventional truck. Furthermore, it also presents greater stability, and prevents the occurrence of derailments in most situations, translating into significantly greater safety in terms of derailment when compared to a conventional Trick.

Na FIGURA 24 tem-se uma vista frontal do invento objeto Truque ferroviário radial esterçante apoiado sobre trilhos (7). Nesta figura é possível se visualizar a roda correspondente à 'banda de rodagem' do conjunto (5), bem como a 'flange rotativa livre' (6), tanto em vista principal quanto em vistas no detalhe. Como se constatará em explanação mais adiante, o presente invento, diferentemente de outros truques ferroviários, que são dotados de eixos rígidos e solidários, o presente invento possui 'rodas livres' (5), que em cada lado do eixo giram independentemente. Além das 'rodas livres' (5), com rotação independente, o sistema é também dotado de 'flanges livres' (6), com flanges que giram em velocidade angular independente das 'bandas de rodagem'. Ou seja, cada roda do presente invento é dividida em 2 [dois], uma 'banda de rodagem' (5), que gira livremente de forma independente à roda do lado oposto, bem como uma roda 'flange' (6), que também gira livremente de forma independente em relação à flange do lado oposto, bem como em relação à roda correspondente. In FIGURE 24 there is a front view of the invention object Steering radial railway track supported on rails (7). In this figure it is possible to visualize the wheel corresponding to the 'tread' of the set (5), as well as the 'free rotating flange' (6), both in main view and in detail views. As will be seen in further explanation Further, the present invention, unlike other railway bogies, which are equipped with rigid and solid axles, the present invention has 'free wheels' (5), which on each side of the axle rotate independently. In addition to the 'free wheels' (5), with independent rotation, the system is also equipped with 'free flanges' (6), with flanges that rotate at an angular speed independent of the 'treads'. That is, each wheel of the present invention is divided into 2 [two], a 'tread' (5), which rotates freely independently of the wheel on the opposite side, as well as a 'flange' wheel (6), which it also rotates freely independently relative to the opposite side flange as well as relative to the corresponding wheel.
Na FIGURA 25, tem-se esquematicamente, de forma isolada, um eixo do presente invento objeto Truque ferroviário radial esterçante, transitando em trajetória retilínea. Nestas condições, apesar das rodas [5] de cada lado serem 'livres e independentes' em termos rotacionais, estas giram na mesma velocidade. Nestas condições, devido à flange livre [6] não estar em contato com o trilho, neste momento a velocidade angular da flange livre [6] é zero ou próxima de zero. In FIGURE 25, there is schematically, in isolation, an axis of the present invention object Steering radial railway trick, traveling in a straight path. Under these conditions, although the wheels [5] on each side are 'free and independent' in rotational terms, they rotate at the same speed. Under these conditions, due to the free flange [6] not being in contact with the rail, at this moment the angular velocity of the free flange [6] is zero or close to zero.
Na FIGURA 26 se tem duas condições, uma com um conjunto de rodagem (rodeiro] do presente invento objeto Truque ferroviário radial esterçante (I), e outra com conjunto de rodagem (rodeiro] de um truque ferroviário tradicional (II]. Pode-se perceber que, na situação do presente invento (I], em uma curva à esquerda, a roda do lado externo à curva desenvolve uma velocidade angular maior, W2, e a roda do lado interno à curva desenvolve uma velocidade angular menor, Wl. Já na situação de um truque ferroviário tradicional (II], por ser completamente solidário, ambas rodas, interna e externa à curva desenvolvem a mesma velocidade angular Wl. Neste sentido, o presente invento objeto Truque ferroviário radial esterçante se caracteriza por maior estabilidade direcional e maior segurança, pois com roda livre praticamente não há escalada do flange da roda no boleto, e, se houver, é mínima, diferentemente de uma situação de um truque ferroviário convencional. Desta forma, o atrito de rodagem é expressivamente menor na condição do presente invento [I] quando comparada com a de um truque tradicional [II]. In FIGURE 26 there are two conditions, one with a wheelset of the present invention, object of a steering radial railway trick (I), and the other with a wheelset of a traditional railway trick (II). realize that, in the situation of the present invention (I), in a left curve, the wheel on the outside of the curve develops a higher angular speed, W2, and the wheel on the inside of the curve develops a lower angular speed, Wl. Now in the situation of a traditional railway bogie (II), as it is completely united, both wheels, internal and external to the curve, develop the same angular velocity Wl. In this In this sense, the present invention object Steering radial rail trick is characterized by greater directional stability and greater safety, as with a free wheel there is practically no climbing of the wheel flange on the billet, and, if there is, it is minimal, unlike a situation with a trick conventional rail. In this way, rolling friction is significantly lower under the condition of the present invention [I] when compared to that of a traditional trick [II].
Na FIGURA 27 visualiza-se um conjunto de rodagem (rodeiro] do presente invento objeto Truque ferroviário radial esterçante. Pode-se perceber que, na situação do presente invento (I), em uma curva à esquerda, a roda do lado externo à curva desenvolve uma velocidade angular maior, W2, e a roda do lado interno à curva desenvolve uma velocidade angular menor, Wl. Estas características resultam em maior estabilidade direcional. In FIGURE 27, a wheelset of the present invention, object of a steering radial railway trick, can be seen. It can be seen that, in the situation of the present invention (I), in a left curve, the wheel on the outside of the curve develops a higher angular velocity, W2, and the wheel on the inside of the curve develops a lower angular velocity, Wl. These characteristics result in greater directional stability.
Na FIGURA 28 se confere a mesma situação da FIGURA 16, porém com a curva sendo realizada para o lado direito. In FIGURE 28, the same situation as in FIGURE 16 appears, but with the curve being made to the right side.
Na FIGURA 29* há esquematicamente a representação de somente uma roda do presente invento objeto Truque ferroviário radial esterçante, transitando em um trilho, indicando o lado externo da roda e do veículo [E] e o lado interno (I), sendo que nesta situação a roda da 'banda de rodagem'In FIGURE 29* there is a schematic representation of only one wheel of the present invention object Steering radial railway trick, traveling on a rail, indicating the external side of the wheel and vehicle [E] and the internal side (I), and in this situation the 'tread' wheel
[5] desenvolve velocidade angular WR, e a roda da 'flange livre' [6] desenvolve velocidade angular WF. Em teoria, quando a 'roda livre' (5), a banda de rodagem está girando com velocidade angular WR, A 'flange livre'[5] develops angular velocity WR, and the 'free flange' wheel [6] develops angular velocity WF. In theory, when 'freewheeling' (5), the tread is rotating with angular velocity WR, A 'freeflange'
[6] está parada, ou seja, desenvolvendo velocidade angular WF igual a zero. Na FIGURA 30 há esquematicamente a representação de somente uma roda do presente invento objeto Truque ferroviário radial esterçante, transitando em um trilho, indicando o lado externo da roda e do veículo [E] e o lado interno (I), executando uma curva à esquerda, sendo que nesta situação a roda da 'banda de rodagem' [5] desenvolve velocidade angular WR, e a roda da 'flange livre' [6] desenvolve velocidade angular WF. Em decorrência da força centrífuga, a roda e a banda de rodagem [5] se deslocam mais à direita do trilho, não havendo o contato da 'flange livre' [6] com o trilho. Em teoria, quando a 'roda livre' (5), a banda de rodagem está girando com velocidade angular WR, A 'flange livre' [6] está parada, ou seja, desenvolvendo velocidade angular WF igual a zero. [6] is stopped, that is, developing angular velocity WF equal to zero. In FIGURE 30 there is a schematic representation of only one wheel of the present invention object Steering radial railway trick, traveling on a rail, indicating the external side of the wheel and vehicle [E] and the internal side (I), executing a curve to the left , and in this situation the 'tread' wheel [5] develops angular velocity WR, and the 'free flange' wheel [6] develops angular velocity WF. As a result of the centrifugal force, the wheel and tread [5] move further to the right of the rail, with no contact between the 'free flange' [6] and the rail. In theory, when the 'free wheel' (5), the tread is rotating with angular velocity WR, the 'free flange' [6] is stationary, i.e. developing angular velocity WF equal to zero.
Na FIGURA 31 tem-se a mesma situação da FIGURA 19, porém em uma curva para o lado direito. Nesta curva, a depender da velocidade e forças centrífugas e dinâmicas, pode haver o contato da 'flange livre' [6] no boleto do trilho. Neste momento, a tendência é da velocidade angular desenvolvida pela flange livre (6), WF aumentar pelo contato com o trilho. Após a curva, a flange livre [6] perde contato com a curva, e sua velocidade angular tende a zero novamente. Esta característica de 'roda livre' [5] e 'flange livre' (6), bem como com o aspecto esterçante em curvas, torna o presente invento 'à prova de descarrilamento'. In FIGURE 31 there is the same situation as in FIGURE 19, but in a curve to the right side. In this curve, depending on the speed and centrifugal and dynamic forces, there may be contact between the 'free flange' [6] and the rail billet. At this moment, the tendency is for the angular velocity developed by the free flange (6), WF to increase due to contact with the rail. After the curve, the free flange [6] loses contact with the curve, and its angular velocity tends to zero again. This 'free wheel' [5] and 'free flange' (6) feature, as well as the steering appearance in curves, makes the present invention 'derailment-proof'.
Na FIGURA 32 pode se observar uma roda tradicional (7), de um truque ferroviário tradicional, realizando uma curva à direita. Neste caso, diferentemente do presente invento objeto Truque ferroviário radial esterçante, a flange é solidária à roda. Desta forma, a depender da velocidade do veículo e dos esforços dinâmicos, pode ocorrer o descarrilamento do vagão e consequentemente de parte da composição também. In FIGURE 32 you can see a traditional wheel (7), from a traditional railway bogie, making a right turn. In this case, unlike the present invention subject to Steering Radial Rail Trick, the flange is integral with the wheel. In this way, depending on the speed of the vehicle and the dynamic efforts, the wagon and consequently part of the train may derail.
