Gear-change box for a motor vehicle's gearbox linked to a clutch has change-gear wheels engaged by meshing and disengaging with toothed gearwheels in a transmission unit

摘要

Sensors (16-18) record the number of revolutions for an intermediate shaft (4), an axle drive shaft (3) and/or change-gear wheels (5-8). Based on recorded number of revolutions, a processor (19) uses a driving mechanism/hydraulic electric motor (20) to increase or reduce the speed of the intermediate shaft to the number of revolutions required for a gear change.
