A method for controlling a drivetrain of a vehicle during a shift process is described. The drivetrain includes a drive engine which is connected via a bow spring dual-mass flywheel to a transmission which can be uncoupled by way of a clutch. The bow spring dual-mass flywheel includes a bow spring which is arranged in a bow spring channel. The method includes detecting that the clutch is closed within the scope of a shift process. Furthermore, the method includes generating a torque intervention at the bow spring dual-mass flywheel independently of a torque request by a driver of the vehicle, in such a way that the bow spring is arranged on the same side of the bow spring dual-mass flywheel after the closing of the clutch as before the opening of the clutch.

Method and control unit for avoiding failure in the drivetrain of a vehicle

A torsional vibration insulator for a drive train of a vehicle, in which a primary element and a secondary element can rotate relative to one another. At least two spring elements extend in an arc in a circumferential direction of the rotational axis and are each supported on a radial outer face by a radial support device. The length of the two spring elements, viewed in the circumferential direction, can be modified by rotating the primary element with respect to the secondary element. The radial support devices of the spring elements have multiple support elements which engage with the radial outer face of the spring elements and which are rotatably mounted in the circumferential direction in such a way that the support elements can be carried along with the spring elements in the circumferential direction when the length of the spring elements is modified, thereby eliminating frictional forces inhibiting rotational motion between the primary element and the secondary element.

Torsional vibration insulator

A divided flywheel having two flywheel masses which can be rotated in relation to each other, counter the action of a damping device, preferable in order to dampen the torsional vibrations of an internal combustion engine.
