Abstract

The lawnmower consists of a chassis (3), a thermal motor (1) and a hydraulic transmission. The motor, which is liquid cooled, has a horizontal output shaft located longitudinally along the chassis and its flywheel directed towards the chassis rear. The engine is mounted on elastic blocks (2). A flexible coupling (4) transmits engine power to the cutting disc (16) or the hydraulic pump (14) through an angle transmission (5) mounted on the chassis. A belt pulley assembly (10), driven from the coupling, drives fan blades (8) for cooling the radiator (6). The cutting disc pulley (18) is float mounted on its rotational axis (20).

Description

La présente invention concerne les tondeuses autoportées et a pour objet une telle tondeuse. The present invention relates to ride-on mowers and relates to such a mower.

Actuellement, les tondeuses sont équipées d'un bac de coupe comportant une, voir deux lames et plus, positionné entre les roues avants et arrières et possédant une éjection latérale ou centrale arrière. Currently, mowers are equipped with a cutting deck comprising one, or even two or more blades, positioned between the front and rear wheels and having a lateral or central rear ejection.

Certaines de ces tondeuses sont munies d'un pont hydrostatique permettant une vitesse d'avancement variable à tout instant aussi bien en marche avant qu'en marche arrière, mais du fait que leurs ponts sont encombrants et disposés dans l'axe des roues arrières, le bac de coupe de celle-ci est à éjection latérale et équipé d'une soufflerie pour le ramassage simultané de l'herbe. Some of these mowers are provided with a hydrostatic bridge allowing a variable forward speed at any time both in forward and in reverse, but because their bridges are bulky and arranged in the axis of the rear wheels, the cutting tank for this is side ejected and equipped with a blower for the simultaneous collection of grass.

Coté motorisation, ces tondeuses disposent d'un moteur à axe horizontal à refroidissement liquide disposé longitudinalement par rapport à leurs châssis, le volant moteur situé vers l'avant de celles-ci tandis que le radiateur est placé entre le tableau de bord et le vilebrequin équipé de l'hélice de ventilation. Motorized side, these mowers have a horizontal axis motor with liquid cooling arranged longitudinally with respect to their chassis, the flywheel located towards the front of these while the radiator is placed between the dashboard and the crankshaft equipped with ventilation fan.

Un ensemble poulies et courroie monté sur le volant moteur et sur un boîtier de transmission servant de pivot de direction permet de transmettre la puissance du moteur vers la tondeuse. A set of pulleys and belt mounted on the flywheel and on a transmission box serving as a steering pivot allows power to be transmitted from the engine to the mower.

Un ensemble cardan transmet la puissance suffisante au pont hydrostatique depuis le vilebrequin du moteur. A universal joint transmits sufficient power to the hydrostatic axle from the engine crankshaft.

La présente invention consiste à réaliser une tondeuse auto-portée à éjection centrale arrière possédant un moteur thermique à refroidissement liquide et à arbre de sortie horizontale équipée d'une transmission hydraulique possédant les mêmes caractéristiques fonctionnelles qu'une transmission hydrostatique. The present invention consists in making a self-supporting mower with rear central discharge having a liquid-cooled heat engine and a horizontal output shaft equipped with a hydraulic transmission having the same functional characteristics as a hydrostatic transmission.

Le moteur "1" à refroidissement liquide et à arbre de sortie horizontale est disposé longitudinalement par rapport au châssis de la tondeuse, celui-ci est situé à l'avant de celle-ci avec son volant moteur dirigé vers l'arrière du châssis. The engine "1" with liquid cooling and horizontal output shaft is arranged longitudinally with respect to the chassis of the mower, this is located at the front thereof with its flywheel directed towards the rear of the chassis.

Pour limiter les vibrations dans l'ensemble du châssis "3", le moteur "1" est monté sur des plots élastiques "2", un accouplement élastique souple "4" assure la transmission de puissance entre ce moteur et un renvoi d'angle "5" fixe sur le châssis. To limit vibrations in the whole chassis "3", the motor "1" is mounted on elastic studs "2", a flexible elastic coupling "4" ensures the transmission of power between this motor and a bevel gear "5" fixed on the chassis.

Le refroidissement du moteur est assuré par un radiateur "6" placé entre le tableau de bord "7" et le moteur "1", une hélice de ventilation "8" montée sur le support "9" fixée au renvoi d'angle "5" est entraînée par un système de poulies courroie "10" entre celle-ci et l'accouplement "4". The engine is cooled by a radiator "6" placed between the dashboard "7" and the engine "1", a ventilation propeller "8" mounted on the support "9" fixed to the bevel gear "5 "is driven by a belt pulley system" 10 "between it and the coupling" 4 ".

Le renvoi d'angle 5" à arbre d'entrée horizontale et de sortie verticale possède sur ce dernier, d'une part, une poulie "11" pouvant transmettre par l'intermédiaire d'une courroie "13" la puissance nécessaire et suffisante à une pompe hydraulique "14" disposant elle aussi d'une poulie "12" et d'autre part, un embrayage électromagnétique "15 pouvant transmettre la puissance du moteur vers le plateau de coupe "16" par un ensemble de poulies "17" et "18" et une courroie "19".  The 5 "angle gear with horizontal input and vertical output shaft has on the latter, on the one hand, a pulley" 11 "which can transmit via a belt" 13 "the necessary and sufficient power to a hydraulic pump "14" also having a pulley "12" and on the other hand, an electromagnetic clutch "15 which can transmit the power of the motor to the cutting deck" 16 "by a set of pulleys" 17 " and "18" and a belt "19".

La position de l'embrayage "15" étant fixe, le plateau de coupe "16" pouvant se déplacer verticalement, pour éviter une usure prématurée de la courroie de transmission "19" due à la différence de hauteur entre les deux poulies "17" et "18", la poulie "18" du plateau de coupe est montée flottante sur son axe de rotation "20" ; de même, la poulie "21" du tendeur "22 sur son axe "23". The position of the clutch "15" being fixed, the cutting deck "16" being able to move vertically, to avoid premature wear of the transmission belt "19" due to the difference in height between the two pulleys "17" and "18", the pulley "18" of the cutting deck is mounted floating on its axis of rotation "20"; similarly, the pulley "21" of the tensioner "22 on its axis" 23 ".

La pompe hydraulique "14" à cylindre variable est câblée par des flexibles "25" à un moteur hydraulique "26" transmettant la puissance développée par l'intermédiaire d'un dispositif pignon chaîne "27" au différentiel "28" placé dans l'axe des roues arrières motrices "29". The hydraulic pump "14" with variable cylinder is wired by hoses "25" to a hydraulic motor "26" transmitting the power developed through a chain sprocket device "27" to the differential "28" placed in the axis of rear driving wheels "29".

Ce dispositif hydraulique par son encombrement réduit offre les mêmes caractéristiques fonctionnelles qu'un pont hydrostatique. This hydraulic device by its reduced size offers the same functional characteristics as a hydrostatic bridge.

Pour une conduite sans à coup de cette tondeuse, le dispositif de commande au pied a été associé à un régulateur de vitesse qui élimine, soit les accélérations, soit les décélérations trop violentes.  For smooth driving of this mower, the foot control device has been associated with a cruise control which eliminates either accelerations or decelerations that are too violent.
