Abstract

The present invention relates to a torque transmission device for a drivetrain of a motor vehicle, which is used for being arranged between a driving shaft (26) of an engine of the motor vehicle and an intermediate shaft (28) to an input shaft of a transmission. The torque transmission device comprises a primary side (30) for being connected with the driving shaft and a secondary side (32) for being connected with the intermediate shaft. The secondary side (32) comprises a hub (34) for being connected with the intermediate shaft (28). The hub (34) is configured with multiple pieces and comprises a hub body (46) for being connected with the secondary side and a hub inside body (38) for being connected with the intermediate shaft. The hub inside body is arranged in the hub body. The hub body and the hub inside body can axially move and can be basically anti-torsionally connected with each other to compensate axial and / or radial reflection and / or movement of the intermediate shaft. According to the hub (34) is configured with multiple pieces, the torque transmission device can compensate coupled axial and / or radial reflection and / or movement of the intermediate shaft (28) and reduce load acting on the input shaft of the transmission.

Description

technical field

[0001] The invention relates to a torque transmission device for a drive train of a motor vehicle and to a drive train of a motor vehicle. Background technique

[0002] In the drive train of a motor vehicle, the torque transfer device is arranged between the drive shaft of the motor vehicle engine and the transmission input shaft. A clutch is arranged between the torque transmission device and the transmission input shaft, which is connected to the torque transmission device via an intermediate shaft. The torque transmission device has a primary side and a secondary side, wherein the secondary side is mounted floating relative to the primary side in order to be able to compensate radial forces which are transmitted by the torque transmission device to the intermediate shaft. This radial force leads to a misalignment or an oblique position of the intermediate shaft. Components of the drive train, such as seals, can be damaged by the secondary side of the tor...
