The invention relates to a hybrid module (1) for a drive train (2) of a motor vehicle, comprising a housing (3), an input shaft (4) which can be rotated relative to the housing (3) and can be connected to an internal combustion engine, an electric machine (5), a carrier (7) rotationally coupled to a rotor (6) of the electric machine (5), a separating clutch (8) operatively introduced between the input shaft (4) and the carrier (7), and a hydraulic actuation unit (9) designed for adjusting the separating clutch (8) between a closed position and an open position, wherein the actuation unit (9) has a sliding element (11) shiftingly acting on multiple friction elements (10a, 10b) of the separating clutch (8), which sliding element (11) encloses a hydraulic pressure chamber (13) towards its first axial side (12a) together with the carrier (7) and is applied with an axial restoring force towards its second axial side (12b) by a restoring spring unit (14), wherein the restoring spring unit (14) and the pressure chamber (13) are designed and coordinated in such a way that, during operation of the hybrid module (1), with the carrier (7) rotating up to a rotational speed of at least 3000 U/min, the restoring force generated by the restoring spring unit (14) is greater than an axial adjustment force of the pressure chamber (13) generated by a centrifugal force in the pressure chamber (13) and acting axially opposite the restoring force, on the sliding element (11) in the direction of the closed position. The invention also relates to a drive train (2) comprising said hybrid module (1).
本发明涉及一种用于机动车辆的传动系(2)的混合动力模块(1),该混合动力模块具有:壳体(3);输入轴(4),该输入轴可以相对于壳体(3)旋转并且连接至内燃发动机;电机(5);承载件(7),该承载件与电机(5)的转子(6)旋转地联接;分离离合器(8),该分离离合器被操作性地引入输入轴(4)与承载件(7)之间;以及液压的致动单元(9),该致动单元将分离离合器(8)调节处于关闭位置与打开位置当中,其中,致动单元(9)具有作用在分离离合器(8)的多个摩擦元件(10a、10b)上的滑动元件(11),并且该滑动元件(11)朝向滑动元件的第一轴向侧部(12a)与承载件(7)一起封围液压室(13)并且朝向滑动元件的第二轴向侧部(12b)被复位弹簧单元(14)施加轴向的复位力,其中,复位弹簧单元(14)和压力室(13)被设计且彼此协调成使得:当混合动力模块(1)运行时,随着旋转承载件(7)的旋转速度达到3000rpm,由复位弹簧单元(14)产生的复位力大于压力室(13)的由压力室(13)中的离心力所产生的轴向调节力,该轴向调节力与所述滑动元件(11)上的沿关闭位置的方向的复位力轴向地相反。本发明还涉及一种具有该混合动力模块(1)的传动系(2)。
