Embodiment Construction

[0025] FIG. 1 shows a cross-sectional view of a torque transmission device 10 according to the prior art. The torque transmitting device 10 is a dual mass flywheel including a primary side 12 and a secondary side 14 . The primary side is connected to a drive shaft 16 of a motor vehicle engine, not shown. The secondary side 14 has a centrifugal pendulum 18 and a hub 20 . The hub 20 is connected on the output side of the secondary side 14 via an intermediate shaft 22 to a transmission input shaft (not shown). The intermediate shaft 22 is in particular connected to a clutch (not shown) in order to transmit torque to the transmission input shaft.

[0026] figure 2 A preferred embodiment of the torque transfer device 24 is shown. The torque transfer device 24 is arranged between a drive shaft 26 and an intermediate shaft 28 of a motor vehicle engine, not shown. The intermediate shaft 28 connects the torque transmission device 24 to a clutch (not shown) and thus to a transmissi...

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...
