Problems solved by technology

Therefore, the assembly and manufacture of the shock absorber is complicated, since it consists of many elements, and the installation of the helical spring in the housing of the guide washer and the web is a difficult operation
[0007] In addition, given the limited volume of the helical spring, the angular travel between the input element and the output element of the torsional vibration damper is limited, so that the helical spring has a greater stiffness for optimal filter deviation

Embodiment Construction

[0053] In the description and claims, the terms "outer" and "inner" and the directions "axial" and "radial" are used to designate the elements of the clutch discs according to the definitions given in the description. Generally, the direction "radial" is perpendicular to the rotation axis X of the clutch friction disc, the direction "axial" is determined from the inside to the outside away from the rotation axis, and the direction "circumferential" is orthogonal to the rotation axis X of the clutch friction disc and is orthogonal to in the radial direction.

[0054]The terms "outer" and "inner" are used to define the relative position of one element with respect to another with reference to the axis of rotation X of the clutch discs, so that an element close to the axis of rotation is called an inner element with respect to a radially peripheral outer element .

[0055] Figures 1 to 4 The shown clutch friction disc 1 is used to be installed to be fixedly connected with a dr...

Abstract

The invention relates to a torsional vibration damper for a clutch friction disc (1), comprising: an input element and an output element, one of which is rotationally movable relative to the other about a rotational axis X; Vibration damping part, which is used to transmit torque and reduce the rotational deviation between the input element and the output element; the input element, which includes two side plates (12, 13) fixedly connected together for rotation, the two side plates are arranged On both sides of the vibration-damping component, accommodating seats for accommodating the vibration-damping component are defined. The damping part includes an elastic piece (22), which is fixedly connected with one of the input element and the output element for rotation and is provided with a cam surface (23). The shock absorber includes a cam follower (24) carried by the other of said input and output elements and adapted to cooperate with said cam surface (23). The cam surface (23) is arranged such that, for an angular travel between the input member and the output member relative to the angular position of rest, the cam follower (24) exerts a bending force on the elastic plate (22) which produces a counter force, said A counter force can reset the input element and the output element towards the angular position of repose.

Description

technical field [0001] The invention relates to a torsional vibration damper for clutch friction discs. [0002] In particular, the invention relates to a pre-vibration damper for mounting friction disks. Such a pre-damper is used to filter out the vibrations produced by the internal combustion engine deviating during deceleration. If there is no pre-damper, then the vibrations entering the gearbox can cause particularly harmful shocks, noise or noise pollution. Background technique [0003] In a motor vehicle, the clutch disc transmits torque between a drive shaft such as the crankshaft of the internal combustion engine and a driven shaft such as the transmission input shaft, since the clutch disc is clamped between the pressure plate and the engine flywheel. In addition, clutch friction plates are generally equipped with torsional dampers, which absorb and dampen vibrations and deflections generated by the engine. [0004] Friction discs sometimes consist of two series-...
