Definitions
- the present invention relates to a railway axis with automatic change to multiple track widths, allowing to solve the problem of the difference in track width adopted in the various railway networks of the world and which supposes a barrier to rail traffic, forcing the realization of transshipment of load or change of manual width.
- the railway axis of the invention is intended to modify the width between wheels in rail vehicles to pass continuously from one track width to another, making them circulate through a section of transition track with rail and counter rail, By varying its width continuously, it connects the two paths of different widths.
- the object of the invention is to eliminate the physical barrier that currently involves the change in width in both merchandise and passenger traffic, to make such a transition smoothly, without the need to make stops and without releasing the wheels during the process of change of width.
- the invention is located in the railway field and specifically in the wheel tandems corresponding to railway vehicles or convoys.
- the Talgo system entitled "Rail axle assembly equipped with automatic track width change and adaptable to conventional merchandise bogies” is known.
- it is not a continuous mounted axle for use and the process of changing the width is carried out by unloading the weight of the wheels.
- It requires internal bearings that present the problem of the detection of internal hot boxes, in addition to the possibility of presenting bad locks in the case of extreme low temperatures.
- Said locking bolts being placed in an upright position and presenting a hollow bridge connecting the vertical release rods upon receiving the head of a suitable profile of an unlocking guide of the width change installation, which requires precise action on the axis.
- the Polish SUW2000 system and the German Type V Rafil stand out.
- SUW2000 presents the complication of transmitting the torque between stands by threaded elements of male-female connection, which lead to serious deterioration in the contact areas, generating gaps that end up supporting the locking system of the wheels destroying it, which adds complexity in Maintenance work
- variable width are known that solve this problem by means of fixing measures, but they do not have a connection as a ball joint and its arrangement is on the external part of the shaft which produces increases in the fatigue of the piece and therefore its break. In addition, they require specifically designed grease boxes, which makes the solution more expensive.
- Other systems of variable width are also known in which the forces required for the realization of the change in width are effected by guiding extra treads with which the railway wheel has, which adds excess weight. In other axes, the process of width change is carried out by means of the participation of pendulons that interact with the platform of width change, said pendulons being elements that add excess weight to the system, as well as complexity in the maintenance work.
- both Rafil Type V and SUW2000 have the characteristic of being exclusively compatible with two different track widths, restricting their use to a single railway border, limiting their possible traffic through other networks, multiple widths, as it is demanding Europe-Asia freight traffic.
- the railway axis with automatic change to multiple track widths, without the need for wheel unloading, is based on the design of a new axle that is equipped on a train, allows it to circulate smoothly between railway networks of different widths.
- the change in width is effected by going through a system installed on the track that is responsible for performing the corresponding maneuvers that allow the unlocking and subsequent interlocking of an internal mechanism provided for that purpose.
- the railway axle of the invention is composed of an axle itself and two wheels that are coupled on said axle by means of fitted bushings, allowing axial displacement of the wheels on the axle under load conditions, without suffering excessive wear or breakage, even under conditions of extreme load due to merchandise traffic.
- the axle has a system of claws that are formed in a sliding sleeve for each wheel, so that the interlocking that allows to keep the track width constant, is achieved by entering the claws of said sleeve in annular grooves of trapecial configuration provided in rings mounted on the wheel hub.
- the shaft can be configured to achieve more than two widths, modifying the length of the sliding sleeve, as well as the length of the shaft, and mounting more rings with trapezoidal annular grooves, in combination with spacer rings provided to separate the rings with annular grooves, and whose separation will establish the appropriate distance until the desired track widths are achieved.
- Each claw sleeve will rotate in solidarity with the shaft, when fixed by means of a base ring zunchado to the axis, the fixation and zunchado being carried out by means of a single nut that is screwed on a threaded section of the zunchado base ring.
- a calibration washer will be used between the clamp sleeve and the base ring that is attached to the shaft.
- an interlocking sleeve associated with one or more prestressed springs will be used.
- the change in width and therefore unlocking or unlocking the wheels will occur when a force is applied that can overcome the resistance offered by pre-tensioned springs installed, and manage to displace the claw sleeve.
- This force will be applied throughout the process of width change thanks to the interaction of the axis with a device or platform of width change installed on the track.
- the force will be applied on a pusher disk integral with the clamp sleeve that will compress the springs installed on the shaft, in order to release the claws from the annular grooves, facilitating the movement of the wheels in the axial direction until the end claws enter of the sleeve in the annular groove corresponding to the new track width to which it is intended to circulate.
- the railway axle also has parts called compasses that are used for coupling between the wheel and the axle in the direction of rotation, each measure being formed by a pair of semi-bars or arms, articulated with each other, with the participation of a kneecap that allows pitching, so that the use of this ball joint allows the absorption of small non-axial movements of the wheel on the axle in its filming, avoiding the breakage of the bolt that connects them.
- the coupling between wheel and axle is produced by connecting a semi-compass on the inside of the wheel by means of a support sleeve and the other semi-compass to the base ring zunchado to the axle.
- the bar supports additionally protect rings fitted with the trapezoidal annular grooves, when the shaft is operating in the widest track configurations.
- the railway axis is complemented by an extendable membrane, bellows type, of one or several folds and that will serve as protection for positions of smaller track width, such that said membrane is attached to the axle and the wheel on its external part, the union being carried out by means of a plate housed in a concave projection of the shaft attached to an external protection piece, while the union to the wheel will be carried out by means of a ring to which the extensible membrane will be attached.
- the axis is designed to withstand extreme loads of freight transport by rail.
- the railway axis is compatible with any bogie and two-axle car available by railway operators.
- the railway axis is valid to change width to more than two widths simultaneously.
- the railway axis constitutes a set of high robustness.
- the railway axis is equipped with sufficient structural strength to accommodate brake discs in its intermediate zone.
- Figure 1. It shows a sectional view of the assembly of the railway axis of variable width with the different components that integrate it in two positions, one of maximum width and another of minimum width.
- Figure 2. Shows a sectional view of the measures participating in the railway axis of the invention, showing the articulated ball joint between both measures.
- Figure 3. Shows a sectional view corresponding to a detail showing the fixing of the ring and the clamp sleeve with respect to the shaft.
- Figure 4.- Shows, finally, a sectional view corresponding to a detail of the extensible membrane constituted by an external protective bellows of the variable width axis.
- variable width axis object of the invention is provided to be able to effect the change of width in a fully satisfactory manner, so that in accordance with what is shown in Figure 1, the railway axis as a whole, it comprises the wheels (1) mounted on the corresponding axle (2) with a sliding adjustment, that is, with the ability to axially displace the wheel (1) on the axle (2).
- This sliding adjustment is produced thanks to the use of tight bushings (3) lubricated by grease on the inside (4) of the wheel (1), allowing the transition from one width to another without the need to release the load of the wheels, even under conditions of high extreme load, such as merchandise traffic.
- the wheels (1) will be locked with respect to the axle (2) by means of a sleeve (5) of claws (5 ') that will prevent its axial displacement, when the claws (5') are placed in trapecial grooves (6 ') provided in rings (6) mounted on the hub (7) of the wheel itself (1), so that the arrangement of the trapecial grooves (6 ') will establish annular grooves that will allow the configuration of two or more track widths, through the modification of the length of the hub (7) of the wheel (1), the length of the axle (1) and the use of the spacer rings (8) that are arranged between the rings (6) of the groove (6 ').
- the claws (5 ') will be in solidarity with the shaft (2), and are fixed by means of a base base ring (9) attached to the shaft, entering the trapecial grooves of the rings (6) where they will be minted in a ring The whole perimeter.
- non-ferrous materials will be used both in the area of contact with the trapezoidal grooves (6') and on the outside in their contact with an interlocking sleeve (10), the latter being provided to prevent the claws (5 ') from leaving the trapezoidal grooves (6') by the action of one or more prestressed springs (1 1).
- the claws (5 ') In order to change the width, the claws (5 ') must be unlocked with respect to the grooves (6'), which is possible by means of a force to defeat one or more prestressed springs (1 1) and to move the interlocking sleeve (10), force applied when said axis circulates through the device or track mechanism provided to effect the change in width.
- the coupling between wheel (1) and axle (2), in the direction of rotation, is based on articulated compasses (13) that connect at one end to the inner part of the wheel (1), by means of a support sleeve ( 14) and at the other end to the base ring (9), fixed and integral with the axle (2) to which the clamp sleeve (5) is also connected (5 '), thus allowing the moment between both wheels to be transmitted (1) , without preventing axial displacement.
- the support (14) of compasses will in turn serve as protection for the rings (6) with trapezoidal grooves (6 '), when the shaft (2) is in the widest configurations.
- Figure 2 shows in greater detail the system of articulated compasses (13), formed by two semi-compasses (15) that allow the rotation by means of an articulation axis (16), as well as the pitching by means of a ball joint (17) coupled to the same axis (16) and housed in one of the semi-bars (15).
- this kneecap (17) By using this kneecap (17), the small non-axial movements of the wheel (1) on the axle (2) will be absorbed, in its normal taxiing, without causing fatigue to the bolt that connects them, thus preventing its rupture.
- Figure 4 shows the protection system when the axis (2) is in a position of smaller track width, said protection system being based on an extensible bellows type membrane (20), of one or more folds, which will remain attached to the axle (2) by means of a plate (21) located on a concave projection (23) of the axle (2) attached to an outer protection piece, and attached to the outer part of the wheel (1) by means of a ring (22 ) to which will be attached to the extensible membrane (20).
- brake discs may optionally be arranged in the intermediate area of the axle, integral with it, or placed jointly with the wheels, in the latter case requiring a simple rudder system to accompany the movement of the wheels during the width transition.
