The invention relates to a drive unit (1) for a hybrid drive train, comprising an internal combustion engine (2), an electric motor (4) and a disconnect clutch (6) arranged radially within a rotor (5) between a crankshaft (3) of the internal combustion engine (2) and the rotor (5) of the electric motor (4), a torsional vibration isolation device (8) being connected downstream of the rotor (5), wherein the torsional vibration isolation device (8) is rotationally connected to the rotor (5) by means of a plug connection (22), and the plug connection (22) is formed by an inner contoured portion associated with the rotor (5) and an outer contoured portion complementarily formed on the torsional vibration isolation device (8). In order to avoid noise and excessive wear at the plug connection (22), the pretensioning device (30) of the plug connection (22) comprises at least one pretensioning element (31) which is fastened to the rotor (5) and which adjusts the pretensioning in the circumferential direction relative to the support surface (34) of the torsional vibration isolation device (8).
本发明涉及一种用于混动动力总成的驱动单元(1),包含内燃机(2)、电动机(4)和在内燃机(2)的曲轴(3)和电动机(4)的转子(5)之间径向地设置在转子(5)之内的分离离合器(6),其中在转子(5)下游连接有扭振隔离装置(8),其中扭振隔离装置(8)借助于插接连接(22)转动配合地与转子(5)连接,并且插接连接(22)由与转子(5)相关联的内轮廓化部和在扭振隔离装置(8)上互补地构成的外轮廓化部形成。为了避免在插接连接(22)处的噪声和过度磨损,插接连接(22)的预紧装置(30)包含至少一个紧固在转子(5)上的预紧元件(31),其调节沿环周方向相对于扭振隔离装置(8)的支撑面(34)的预紧。
