DOUBLE CLUTCH TRANSMISSION FOR AN ELECTRIC VEHICLE, AND DRIVE UNIT FOR AN ELECTRIC VEHICLE
20220128099 · 2022-04-28 ·

The invention relates to a double clutch transmission (10) for an electric vehicle, comprising an input shaft (40), a first component clutch (11), by means of which the input shaft (40) can be coupled to a first output shaft (41), and a second component clutch (12), by means of which the input shaft (40) can be coupled to a second output shaft (42), wherein the second output shaft (42) is configured as a hollow shaft. The second output shaft (42) comprises a flange section (65) which extends in the radial direction (r). The first component clutch (11) can be actuated by a first actuating unit (51) which comprises a driver, which driver engages through the flange section (65) in the axial direction (x) and is connected fixedly to the second output shaft (42) so as to rotate with it. The driver can be actuated in the axial direction (x) via a first release bearing, and the first component clutch (11) can be actuated in the axial direction (x) by the driver via a second release bearing. The invention also relates to a drive unit for an electric vehicle, which drive unit comprises a double clutch transmission (10) according to the invention and an electric motor (5) for driving the input shaft (40) of the double clutch transmission (10).

Vehicle powertrain system

A vehicle powertrain includes a power source, a clutch arrangement and a housing, the clutch arrangement arranged between the power source and a transmission. The clutch arrangement includes: a first clutch arranged to couple the power source to a first input shaft of the transmission and a second clutch arranged to couple the power source to a second input shaft of the transmission; and a torque transmission member having an extension in a radial direction and adapted to transmit torque from the power source to one of the first or second input shafts. The torque transmission member includes clutch lamellae carriers for the first and second clutches. The torque transmission member is journaled at a radially inner portion against the housing via one or more first bearings, and an output rotor shaft of the power source is journaled against the housing via one or more second bearings.
