A torque transfer device is provided, for a powertrain of a motor vehicle, comprising an electric motor having a stator and a rotor rotatable relative thereto. A control system is provided which can output a current pulse to the electric motor, wherein the current pulse effects a rotary motion of the rotor in a first direction of rotation and through a first angle of rotation and thus effects an induced voltage, which is received by the control system to determine the direction of rotation or the rotary position of the rotor in relation to the stator. The rotor is connected to a torsional vibration damper comprising a damper input and a damper output; rotatable in a limited manner in relation to the damper input, against the effect of energy storage elements, and the rotary motion of the rotor causes a relative rotation between the damper input and the damper output.

A hybrid module is configured for arrangement in a torque path upstream from a transmission and downstream from an internal combustion engine. The hybrid module includes an electric motor and a clutch. The electric motor includes a rotor and a rotor carrier supporting the rotor. The hybrid module also includes a damper assembly fixed to the rotor carrier. The clutch is configured for selectively coupling the damper assembly to a shaft drivingly coupled to the internal combustion engine. The damper assembly includes an output configured for connecting to an input shaft of the transmission.

A hybrid vehicle having a pendulum damper in which resonance at around an idling speed of an engine can be prevented to improve N.V. performance. The hybrid vehicle comprises an engine and at least one motor. In the hybrid vehicle, a power transmission path is formed between the engine and drive wheels. In the power transmission path, a pendulum damper is disposed to suppress torsional vibrations, and a disconnecting clutch is disposed to selectively interrupt power transmission between the engine and the pendulum damper.

A power transfer unit for transferring power from a front wheel side to a rear wheel side comprises: a hollow transfer input shaft which is coupled to an engine and through which a right-side front-wheel axle is penetrated; a transfer output shaft disposed to extend in a direction orthogonal to the transfer input shaft; a transfer drive gear provided on an outer periphery of the transfer input shaft; and a transfer driven gear provided on an outer periphery of the transfer output shaft and meshed with the transfer drive gear. It further comprises a damper mechanism configured to absorb a fluctuation in torque input from an engine side into the transfer input shaft. The damper mechanism is disposed such that an intermediate portion and a left end-side portion thereof overlap the transfer driven gear in an extension direction of the transfer output shaft, in top plan view.
