Torque transmission device

The invention relates to a torque transmission device (100) having a torsional vibration damper (101) arranged about an axis of rotation (d) and a friction clutch (102) connected thereto in a rotationally fixed manner by means of a plug connection (103). In order to reduce the influence of centrifugal forces on the transmission performance of the friction clutch (102), the friction clutch (102) can be automatically actuated by means of a hydraulic actuator having a piston (135) which can be axially displaced as a function of pressure in a pressure chamber (138) which can be pressurized by a pressure supply device via a pressure channel (139) in a shaft section (140), and the pressure chamber (138) is arranged only radially within the plug connection (103). 本发明涉及一种扭矩传递装置(100)，该扭矩传递装置具有围绕转动轴线(d)布置的扭转振动减振器(101)和借助插接连接部(103)与其不可相对转动地连接的摩擦离合器(102)。为了降低离心力在摩擦离合器(102)的传递性能上的影响，摩擦离合器(102)可借助液压致动器自动地操作，液压致动器具有能够根据压力在可由压力供给装置经由压力通道(139)在轴区段(140)中加载压力的压力腔(138)中轴向移动的活塞(135)，并且压力腔(138)仅沿径向布置在插接连接部(103)之内。
