ABSTRACT:
The power train of a motor vehicle employs a torque transmitting apparatus having a hydrokinetic torque converter with a lockup clutch and a torsional damper between the output member of the clutch and the hub of the turbine in the cover of the torque converter. The torque capacity of the damper is less than the nominal torque of the engine whose output element drives the cover of the torque converter. The lockup clutch is designed in such a way that the transmission of torque from the cover to the damper can be regulated in several stages, one of which involves the transmission of torque within a range of between about 10% and 60% of the maximum torque transmitted by the engine and another of which involves the transmission of torque corresponding to not less than 60% of the maximum torque transmitted by the engine.
