Abstract: Torsional vibration damper for a drivetrain of a motor vehicle, having a primary element rotatable around a rotational axis and a secondary element rotatable relative to the primary element against an energy storage. The energy storage includes a helical compression spring unit. The helical compression spring unit is provided in a spring channel, and the helical compression spring unit includes an outer spring. The outer spring is formed as an arc spring and an inner spring is provided inside of the outer spring and virtually coaxial to the outer spring. The inner spring when disassembled from the helical compression spring unit is formed as a straight helical compression spring. The inner spring has a winding direction that is opposed to a winding direction of the outer spring and the inner spring when installed in the torsional vibration damper, is shorter than the outer spring by a value of x.

Abstract: A hybrid drive module (1) for a motor vehicle includes a housing (GG), a torque converter (TC), and an electric machine with a rotor (R) and a stator (S). The rotor (R) is arranged on a rotor carrier (RT), which is fixedly connected to a hub (N). The hub (N) is rotatably supported via at least one first bearing (L1) and is supported in radial and axial directions against a bearing shield (LS). The hub (N) is rotationally fixed to a converter housing (TCH) of the torque converter (TC) via a rivet joint (RI) or a screw connection. A drive train for a motor vehicle including such a hybrid drive module (1) is also provided.

Abstract: A hydrodynamic coupling includes a housing coupled to a driveshaft having an impeller and a turbine wheel arranged in the housing driven by the impeller and a first damper arrangement by which the housing is coupled to a driven member by a lockup clutch. The first damper arrangement includes a first torsional vibration damper connected to the lockup clutch that is rotatable around an axis of rotation against the action of a first damper spring arrangement. A second torsional vibration damper is connected to the first torsional vibration damper and rotatable around the axis of rotation against the action of a second damper spring arrangement. The turbine wheel is connected to an intermediate torsional vibration damper region including a first secondary side, a second primary side, a second damper arrangement has a deflection mass carrier connected to the second secondary side.
