Design of the gearbox
Double clutch and torque curve
The double clutch is located in the bell housing.
It consists of two conventional clutches, which are comprised to form a double clutch. During the remainder of this
lk
self-study programme, the clutches are referred to as K1 and K2.
Clutch K1 transfers the torque to drive shaft 1 via splines. From drive shaft 1, the torque for gears 1 and 3 is
transferred to output shaft 1 and that for gears 5 and 7 to output shaft 2.
Clutch K2 transfers the torque to drive shaft 2 via splines.
It transfers the torque for gears 2 and 4 to output shaft 1 and the torque for 6th gear and reverse gear to output
shaft 2. Via reverse gear intermediate gear R1, the torque is then passed on to reverse gear R2 on output shaft 3.
All three output shafts are connected to the differential final drive gear.
