VEHICULE AUTOMOBILE COMPORTANT UN DISPOSITIF POUR ACTIONNER LE SYSTEME DE TRANSMISSION DE COUPLE ET LA TRANSMISSION

摘要

The invention concerns a motor vehicle with an engine, a gearbox and a torque-transmission system (3) disposed in the torque flow between engine and gearbox, with an actuator unit (13) for actuating the coupling operation and the gear-change and selection operation in order to change gear automatically. The actuator unit (13) is supplied by a hydraulic unit, comprising a hydraulic pump (14) and optionally a pressure accumulator (28), with a pressurized medium for deliberately triggering a gear-change operation. The actuator unit (13) comprises at least one actuator and the hydraulic fluid connections which are triggered for the controlled actuation of the gear-change and selection operation.
