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 power train 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 (5) has two sub-clutches (10, 16), by means of which the torque input component (2) and the torque output component (3) can be connected so as to transmit a torque. One of the two sub-clutches (10, 16) is designed asa positive clutch (16, 17) and the other sub-clutch of the two sub-clutches (10, 16) is designed as a friction clutch (10, 11). 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 powertrain of a motor vehicle, which has a torque input member acting as a drive element, such as a crankshaft or a component fixed relative to the crankshaft, the torque input member being used in particular for introducing a first drive Torque of a machine, such as an internal combustion engine in particular; and a torque output member acting as a driven element, such as a transmission input shaft or a driven shaft of a second drive machine, especially an electric motor, wherein the torque output member can be passed through Preferably, using a friction pair, such as friction linings and / or laminations, a shiftable clutch, in particular via a separating clutch, is connected in a torque-transmitting manner to the torque input component, wherein the clutch has two partial clutches, the torque The input member and the torque output member can be connected in a torque-transmitting manner by means of a partial cl...

Problems solved by technology

[0004] However, the prior art always has the disadvantage that such a clutch unit and the upstream torsional vibration damper require a large installation space and that the costs for reducing the unevenness of rotation are very high

The prior art also has the disadvantage that in wet-running, friction-based release clutches, additionally, high losses are caused by the belt displacement; in dry-running, friction-based release clutches, the installation space requirement is large; and in a form-lock based release clutch, moreover difficult to achieve steerability
