Abstract (en)
[origin: WO2020147873A1] Clutches are commonly integrated into electric drive axles in order to interrupt or bypass the torque flow for shifting processes. In the process, the electric axle can be designed as a multi-gear axle using a double clutch in order to achieve a higher final speed and to operate an electric motor in a more efficient power range. For this purpose, a dry double clutch (5) is proposed for an electric axle (1), comprising a clutch unit (6), which has a first clutch device (7) for connecting a drive shaft (4) to a first output shaft (9a) and a second clutch device (8) for connecting the drive shaft (4) to a second output shaft (9b); and an actuation unit (13), which has a first actuation device (14) for actuating the first clutch device (7) and a second actuation device (15) for actuating the second clutch device (8), wherein the first clutch device (7) is closed when the first actuation device (14) is not actuated, and the second clutch device (8) is open when the second actuation device (15) is not actuated. A first pressure force (F1) can be applied to the first clutch device (7) by means of the first actuation device (14) in order to open the first clutch device, and a second pressure force (F2) can be applied to the second clutch device (8) by means of the second actuation device (15) in order to close the second clutch device.
