Clutch unit with torsional vibration damper as a clutch support, and hybrid module comprising clutch unit

Abstract

The invention relates to a clutch unit (1) for the powertrain of a motor vehicle, comprising a torque input component (2) which acts as a drive element and a torque output component (3) which acts asan output element and which can be connected to the torque input component (2) so as to transmit a torque via a clutch (5) that can be shifted using friction partners (4). The clutch unit also comprises a torsional vibration damper (6) comprising two masses (7, 8) which are damped relative to one another in order to reduce rotational irregularities, said torsional vibration damper being arranged between the torque input component (2) and the torque output component (3), wherein at least one of the two masses (7, 8) of the torsional vibration damper (6) is simultaneously designed as a support (9) for one friction partner (4). The invention additionally relates to a hybrid module comprising a first drive machine, the output shaft of which can be connected to the output shaft of a second drive machine or a transmission input shaft via such a clutch unit (1).

Description

technical field [0001] The invention relates to a clutch unit for a drive train of a motor vehicle, which has a torque input component acting as a drive element, such as a crankshaft or an opposing The fixed part of the crankshaft and the clutch unit have a torque output component acting as a driven element, such as a transmission input shaft or a driven shaft of a second drive machine, in particular an electric motor, wherein the torque output component can be driven via a clutch. The shifted clutch, in particular via a separating clutch, is connected in a torque-transmitting manner with a torque input component using friction fittings, such as friction linings and / or discs, and the clutch unit has a torsional vibration damper with Two masses damped relative to each other for reducing rotational inhomogeneities, in particular of the internal combustion engine, the torsional vibration damper is arranged between the torque input component and the torque output component.

Problems solved by technology

[0004] However, the prior art always has the disadvantage that such a clutch unit with an upstream torsional vibration damper requires a large installation space and that the cost for reducing the rotational unevenness is very high

In addition, in wet, friction-based release clutches, high losses occur due to the drag torque, in dry, friction-based release clutches, the installation space requirement is additionally high, and in form-lock-based release clutches It is also difficult to achieve controllability in
