Following a system for synchronizing a gearbox wireless weather and method of controlling the synchronization system.

摘要

The present invention relates to a vehicle with a synchronization system of a gearbox controlled and its method of commande.le vehicle according to the invention comprises a motor (10), a gearbox controlled (12) comprising a primary shaft (26) and a secondary shaft (28). the system comprises a brake (59) interposed between the primary shaft (26) and a casing (30) of the gearbox (12). The brake is able to be active in slowing down the primary shaft (26) when the speed of the latter must be abaissée.un device for downshifting of the system is able to control an acceleration of the motor (10) when the brake (59) is inactive and a clutch (14) is in a closed position in order to increase the speed of the primary shaft (26), whereas a sleeve (56, 57, 58) is in the uncoupled position so that the primary shaft (26) rotates independently of the secondary shaft (28).
