Clutch unit with torsional vibration damper as clutch carrier, hybrid module with clutch unit

Abstract

The invention relates to a clutch unit (1) for a drive train of a motor vehicle, having a torque input element (2) acting as a drive element, a torque output element (3) acting as a driven element, The torque output member is torque-transmissibly connectable to the torque input member (2) via a clutch (5) which can be shifted using a friction fit (4) and has a torsional vibration damper (6), The torsional vibration damper has two masses (7, 8) for reducing rotational inhomogeneities damped relative to each other, the torsional vibration damper is arranged between the torque input member (2) and the torque output member (3) Between, wherein at least one of the two mass parts (7, 8) of the torsional vibration damper (6) is simultaneously designed as a carrier (9) for the friction fit (4). Furthermore, the invention relates to a hybrid module having a first drive machine whose output shaft can be connected via such a clutch unit (1) to the output shaft of a second drive machine or the transmission input shaft .

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
