Abstract

L'invention concerne un dispositif de réduction des chocs à la sélection et au passage des vitesses dans une transmission automatique de véhicule automobile. Le dispositif comprend un accumulateur de pression 20 comprenant un piston étagé 23 relié à un embrayage avant 1, un embrayage arrière 2, un servo-mécanisme 3 d'actionnement du second frein et un frein bas et arrière 4 faisant partie de la transmission automatique. L'accumulateur 20 permet de réduire la pression de commande ce ces éléments. L'invention concerne les transmissions automatiques de véhicule automobile.The invention relates to a device for reducing shocks when selecting and changing gears in an automatic transmission of a motor vehicle. The device comprises a pressure accumulator 20 comprising a stepped piston 23 connected to a front clutch 1, a rear clutch 2, a servo-mechanism 3 for actuating the second brake and a low and rear brake 4 forming part of the automatic transmission. The accumulator 20 makes it possible to reduce the control pressure of these elements. The invention relates to automatic transmissions of a motor vehicle.
