Embodiment Construction

[0030] figure 1 A schematic diagram of a torsional vibration damper 10 with a torque limiter is shown. The torsional vibration damper 10 comprises an input part 14 mounted rotatably about an axis of rotation 12 and an output part 18 arranged relative to the input part 14 so that it is rotatably limited about the axis of rotation 12 against the action of a spring device 16 . Arranged between the input part 14 and the output part 18 are two torque-transmitting intermediate elements 20 , which are respectively coupled to the input part 14 and the output part 18 via a cam drive 22 and connected to the input part 14 It is configured to move radially when rotating relative to the output member 18 . Between the intermediate elements 20 there is a spring device 16 which comprises at least two spring elements 24 or energy stores arranged at a distance from one another.

[0031] The input part 14 is thus coupled to the output part 18 via an intermediate element 20 , wherein two cam dr...

Abstract

The invention relates to a torsional vibration damper (10) with a torque limiter, in particular for a clutch disc in a drive train of a motor vehicle, having an input part (14) mounted rotatably about an axis of rotation (12) ) and relative to the input member (14) around the axis of rotation (12) against the action of the spring device (16) limited rotation of the output member (18), wherein between the input member (14) and the output member (18) At least two torque-transmitting intermediate elements (20) are arranged between them, and the intermediate elements move radially by means of a cam transmission mechanism (22) when the input part (14) and the output part (18) rotate relative to each other, wherein through the cam transmission The design of the mechanism (22) and / or the construction of the spring device (16) forms a torsional characteristic curve (32) of the driving torque with respect to the rotation angle during relative rotation between the input part and the output part, and the torsional characteristic curve has a damping effect The damper stage (34) and the final stage (36) adjacent to the shock absorber stage (34), wherein the shock absorber stage (34) accounts for the shock absorber performance of the driving torque with respect to the rotation angle, and the final stage (36) includes the drive Torque Torque limit with respect to the angle of rotation.

Description

technical field [0001] The invention relates to a torsional vibration damper with a torque limiter, in particular for a clutch disk in a drive train of a motor vehicle. [0002] Furthermore, the invention relates to a clutch plate for arrangement in a drive train of a motor vehicle, which has a torsional vibration damper according to the invention. [0003] Furthermore, the invention relates to a flywheel having a clutch disk with a torsional vibration damper according to the invention. Background technique [0004] Torsional vibration dampers are generally known and are usually arranged between the crankshaft of the internal combustion engine and the drive shaft of the motor vehicle. Through the strokes of the internal combustion engine, the crankshaft is excited by periodic disturbances. In order not to transmit disturbances to the drive train, torsional vibration dampers are provided, which shift disturbing resonances that occur in different operating situations into a ...
