Abstract:
A motor-vehicle drive train including a differential which has a differential input part and two differential output parts, comprising: a coupling arrangement for two of the three differential parts including a torque-damping friction clutch capable of transmitting clutch torque without slippage, which is sufficiently small such that, in the case of torque shocks and in the case of differences in torque, as they normally occur between two differential parts during conventional motor-vehicle operation, the clutch automatically converts to a friction slip operation, said friction clutch including a temperature-dependent adjusting means which, at least in a predetermined temperature range, reduces the clutch-engaging forces and thus the transmittable clutch torque, as the clutch temperature increases and increases clutch-engaging forces as the clutch temperature decreases.
