Abstract
A torque transmission device for a drive train of a motor vehicle driven by an internal combustion engine. The device includes an input part and an output part having a common axis of rotation around which the input part and the output part are jointly rotatable relative to one another, and a spring damper arrangement that has at least one energy storage device. A friction device is effective between the input part and the output part and is arranged radially outside the at least one energy storage device, in order to provide a torque transmission device having a construction that is optimized with respect to the installation space.
Claims15
A torque transmission device for a drive train of a motor vehicle driven by an internal combustion engine, said torque transmission device comprising:
- an input part and an output part having a common axis of rotation around which the input part and the output part are jointly rotatable and are rotatable relative to one another,
- a pendulum mass carrier part of a centrifugal pendulum device connected for co-rotation with the output part, wherein the centrifugal pendulum device is axially and radially spaced from the input part,
- a spring damper arrangement for damping torsional vibrations in the drive train and including at least one energy storage device,
- an axially operating friction device that is effective to frictionally damp relative rotation between the input part and the output part, wherein the friction device is arranged radially outside the at least one energy storage device and is positioned between and is in surface-to-surface contact with the input part and with the pendulum mass carrier part, and
- an axially acting spring carried by one of the input part and the pendulum mass carrier part and that acts against and axially biases the friction device against the other of the input part and the pendulum mass carrier part.
