Torque transmission unit in drive train of motor vehicle has each of two transmission input shafts coupled to engine's crankshaft by friction clutch, each with drive side and driven side friction units interacting with one another

摘要

The torque transmission unit has each of two transmission input shafts (2,3) coupled to the engine's crankshaft (4) by means of a friction clutch (10,11) each of which has drive side and driven side friction units (10a,11a) which by axial pressure along a rotational axis (2a) of at least one of the input shafts interact with one another to create a friction engagement. The friction units are formed from a number of friction partners (12a,12b,13a,13b) in a layered arrangement in the axial direction and alternating on the drive side and driven side. Independent claims are also included for the following: (A) a double clutch transmission with the aforesaid torque transmission unit; (B) a drive train with an internal combustion engine and double clutch transmission with the aforesaid torque transmission unit between them; and (C) a use for the torque transmission unit which is in the drive train in a motor vehicle.
