Power transmission in the gears
Torque is transmitted into the gearbox via either clutch K1 or K2.
Each clutch drives a drive shaft.
Drive shaft 1 is driven by clutch K1 and
drive shaft 2 is driven by clutch K2.
Power is transmitted to the differential via
- output shaft 1 for gears 1, 2, 3, and 4,
- output shaft 2 for gears 5, 6 and 7, and
- output shaft 3 for reverse gear and the parking lock.
