Abstract
A drive train unit for a drive train of a motor vehicle includes an input component for introducing a torque, a torsion damper for damping rotational non-uniformities, an output component for outputting the torque, and an intermediate hub. The torsion damper is connected in a torque-transmitting manner to the input component. The torsion damper includes a main damper having a spring element, and a radial inner side. The output component is connected in a torque-transmitting manner to the torsion damper. The output component is arranged radially outside of the spring element. The intermediate hub connects the torsion damper to the output component on the radial inner side.

A drive train unit for a drive train of a motor vehicle, comprising:
- an input component for introducing a torque;
- a torsion damper for damping rotational non-uniformities:
- connected in a torque-transmitting manner to the input component;
- and
- comprising:
- a main damper comprising a spring element;
- and
- a radial inner side;
- an output component for outputting the torque:
- connected in a torque-transmitting manner to the torsion damper;
- and
- arranged radially outside of the spring element;
- an intermediate hub connecting the torsion damper to the output component on the radial inner side of the torsion damper;
- and
- a pre-damper comprising:
- a pre-damper cage;
- a pre-damper spring element;
- and
- a pre-damper hub flange:
- rotationally coupled to the pre-damper cage via the pre-damper spring element;
- and
- connected in a torque-transmitting manner to the intermediate hub via a profiled gearing.
