Embodiment Construction

[0014] exist figure 1 The torque transmission device 1 shown in section in FIG. 1 is arranged between the drive shaft 2 and the torque transmission shaft 3 . The torque transmission device 1 transmits the drive torque from the drive shaft 2 to the torque transmission shaft 3 and serves here for damping or damping torsional vibrations. The torque transmission device 1 comprises a primary side 4 , which is fixedly connected to the drive shaft 2 , and a secondary side 5 , which is fixedly connected to the torque transmission shaft 3 .

[0015] The primary side comprises a primary flange 6 which together with the outer ring 7 forms a receiving chamber 8 for receiving a spring assembly 9 as an energy store. The primary flange 6 comprises a substantially disk-shaped region 10 which, in its radially outer region, merges into a cup-shaped region 11 which extends substantially in the axial direction with respect to the axis of rotation R. Unless stated otherwise, the axial direction ...

Abstract

Disclosed is a torque transmission device (1), in particular for use in a motor vehicle hybrid drive system, comprising a primary side (4) and a secondary side (5) which are interconnected via an energy accumulator (9) and which can be twisted relative to one another against the force of the energy accumulator. In order to prevent damage caused by torque peaks, the torque transmission device comprises a means (49) for limiting the transmissible torque.

Description

technical field [0001] The invention relates to a torque transmission device, in particular for use in a hybrid drive of a motor vehicle, comprising a primary side and a secondary side, the primary side and the secondary side being interconnected via an energy store, and the primary side The side and the secondary side can be twisted relative to each other against the force of the accumulator. Background technique [0002] A hybrid drive in a motor vehicle comprises at least two energy converters and two energy storage systems installed in the vehicle for driving the vehicle. Typically, one of the energy converters is an internal combustion engine, typically a petrol or diesel engine, and the second energy converter is an electric motor. Accordingly, the energy storage system is a fuel tank and a battery. [0003] A torque transmission device known as a dual-mass flywheel (ZMS), comprising a primary side and a secondary side, which are interconnected by means of an accumul...
