DESCRIPTION
La présente invention concerne un dispositif de cliquet réversible avec changement automatique pour permettre de tourna ner avec un motoculteur et de remplacer le différentiel des tondeuses auto-portées et micro-tracteur.DESCRIPTION
The present invention relates to a reversible ratchet device with automatic change to allow turning with a tiller and replacing the differential of self-propelled mowers and micro-tractors.
L'entrainement des roues motrices lorsqu'on tourne avec un motoculteur ne possédant pas de crabot,fait patiner une roue qui se syncronisera avec l'autre en repartant en ligne droite. The drive of the driving wheels when turning with a tiller without a dog, causes a wheel to skate which will synchronize with the other by starting in a straight line.
Dans le cas où une roue motrice d'une tondeuse auto-portée et/ou d'un micro-tracteur a moins d'adhérance,elle patine en empêchant l'autre de tourner. If one drive wheel of a self-propelled mower and / or a micro-tractor has less grip, it skates preventing the other from turning.
Le dispositif selon l'invention permet de remédier à ces inconvénients. I1 comporte un boîtier cylindrique contenant des compartiments hémisphériques en forme de coeur non fermé en pointe qui recoivent des billes réparties respectivement dans chacun d'eux; celles-ci se déplacent dans leurs compartiments sous 1 'effet de la rotation et de la pesanteur. The device according to the invention overcomes these drawbacks. I1 comprises a cylindrical housing containing hemispherical compartments in the shape of a heart not closed at the point which receive balls distributed respectively in each of them; these move in their compartments under the effect of rotation and gravity.
Un deuxième boîtier cylindrique également, muni de dents arrondies qui s' assemble avec le premier. La fermeture de l'ensemble de l'invention se fait au moyen d'un seul flasque la téral
Selon des modes particuliers de réalisation: - les compartiments du premier boîtier peuvent être hémisphériques dans la totalité de la pièce. A défaut ils le seront à chaque extrémité, le couloir intermédiaire étant cubique.A second cylindrical case also, provided with rounded teeth which assembles with the first. The closure of the whole of the invention is done by means of a single flange the teral
According to particular embodiments: - the compartments of the first housing can be hemispherical throughout the room. Otherwise they will be at each end, the intermediate corridor being cubic.

La figure 10 représente en coupe, le profil de la pièce représentée figure 9
En référence à ces dessins, le dispositif comporte une pièce A alésée en son centre (23) pour sa fixation sur le motoculteur (ou autre engin), contenant une bille (50) dans chacun de ses compartiments (20) (21), s'emboîtant dans la pièce B alesée en son centre (7). L'alésage de la pièce C (7) vient s'emboîter sur la pièce A (24) pour fermer l'ensemble et permettre la rotation de la pièce A dans le dispositif. L'axe (24) extérieur comprend deux orifices (22) pour la fixation sur l'arbre de roue.Figure 10 shows in section, the profile of the part shown in Figure 9
With reference to these drawings, the device comprises a part A bored in its center (23) for its attachment to the rototiller (or other machine), containing a ball (50) in each of its compartments (20) (21), s 'fitting into part B bored in its center (7). The bore of the part C (7) comes to fit on the part A (24) to close the assembly and allow the rotation of the part A in the device. The outer axle (24) includes two holes (22) for fixing to the wheel shaft.
Lors du fonctionnement du motoculteur (ou autre engin) le dispositif fixé par la pièce A sur l'arbre de roues (23) fait circuler les billes (50) par sa rotation et l'effet de la pesanteur. Celles-ci viennent loger dans l'extrémité de leur compartiments respectif (20) de la pièce A, se nichant dans une dent arrondie (1) de la pièce B, l'obligeant à tourner à la même vitesse que la pièce A ou à une vitesse supérieure. During the operation of the tiller (or other machine) the device fixed by the part A on the wheel shaft (23) circulates the balls (50) by its rotation and the effect of gravity. These are housed in the end of their respective compartments (20) of part A, nestling in a rounded tooth (1) of part B, forcing it to rotate at the same speed as part A or to a higher speed.
Ce dispositif agissant quel que soit le sens de rotation de l'arbre des roues par la circulation réversible des billes (50) dans le compartiment (21) avec une même finalité, d'une extrémité (20) à l'autre.This device acting whatever the direction of rotation of the wheel shaft by the reversible circulation of the balls (50) in the compartment (21) with the same purpose, from one end (20) to the other.
Le dispositif selon l'invention permet l'entraînement des roues motrices lorsqu'on tourne avec un motoculteur ou autre engin) sans faire patiner une roue Le patinage par manque d'adhérence d'une roue est également empêché (pour engin avec différentiel). The device according to the invention allows the driving of the driving wheels when turning with a tiller or other machine) without causing a wheel to slip. Skating by lack of grip of a wheel is also prevented (for machine with differential).
