Patent ID: 7213480

Claim:
A motor vehicle transmission, comprising an input shaft intended for drivable coupling to a motor, a first intermediate shaft having a first primary gearwheel mounted rotatably on the shaft, a second intermediate shaft having a second primary gearwheel mounted rotatably on the shaft, first and second clutch members coordinated with the first and second primary gearwheel respectively and enabling the first and second primary gearwheels to be locked alternately onto a respective intermediate shaft so as to transmit torque from the input shaft to the respective intermediate shaft, a main shaft, and gearwheels supported by the intermediate shafts and the main shaft, which said gearwheels engage with one another in pairs so as to transmit torque from one or other intermediate shaft to the main shaft and whereof at least one gearwheel in each pair is a disengageable running wheel, wherein a first drive gearwheel, upon engagement of a first clutch device, is arranged to transmit torque from the input shaft to both the first and second primary gearwheels simultaneously for driving of the first and second primary gearwheels in a first direction, and a second drive gearwheel, upon disengagement of the first clutch device and engagement of a second clutch device, is arranged to transmit torque from the input shaft to both the first and second primary gearwheels simultaneously for driving of the first and second primary gearwheels in a direction opposite to the first direction.
