Definitions
- the invention relates to a friction ring, in particular a friction ring for a torsional vibration damper and a torsional vibration damper with such a friction ring.
- Torsional vibration dampers with friction rings are known in the art.
- DE 10 2009 018 574 A1 discloses a torsional vibration damper with an input part and an output part and with a friction ring, the friction ring with its friction surface being arranged in frictional contact with respect to a friction surface of an input part, the friction ring being in frictional contact with the output part Game or play-free rotatably connected.
- the input part of the torsional vibration damper is rotated relative to the output part of the torsional vibration damper and there is a targeted friction between the input part and the output part of the torsional vibration damper in the relative rotation, which supports the torsional vibration damping.
- the friction ring is thereby pressed axially by a disc spring against the friction surface of the output part. In this case, a spreading of the characteristic of the torsional vibration damper is effected by the targeted integration of the friction ring.
- the friction ring supports the torsional vibration damping, which must be taken into account by the arrangement with the plate spring for pressing an effort for assembly.
- the object of the torsional vibration damper is achieved by a torsional vibration damper having the features of claim 1.
- An embodiment of the invention provides a torsional vibration damper having an input part and an output part and having a friction ring with a friction surface, wherein the friction ring with the friction surface against a friction surface of the input or output part is arranged in frictional contact and wherein the friction ring with the output or input part with play or backlash rotatably connected, characterized in that the Friction ring has an arm which protrudes from the friction ring and biased against the output or input part such that the friction surface of the friction ring is acted upon against the friction surface of the output or input part.
- the friction ring is not acted upon by another component, which must be mounted separately, but it is acted upon directly by the integrally formed arm.
- the input part or the output part of the torsional vibration damper can be directly the respective input part or output part, but it can also be an element connected to the input part or output part.
- the arm is a circumferential annular arm which forms a sealing lip.
- the circumferential ring-shaped arm of the arm can also serve as a sealing lip to seal a space region of the torsional vibration damper can.
- This is particularly advantageous in torsional vibration dampers with grease or oil-lubricated force accumulators, when the chamber in which the energy accumulator or stores are accommodated, is sealed by means of a sealing lip of the friction ring. This gives the friction ring an additional functionality that goes beyond the friction and associated hysteresis and its own contact pressure.
- the arm bears sealingly against the starting or input part as a sealing lip.
- a space area is completed because the sealing lip may rest against one element of the torsional vibration damper, while the friction surface may abut another element of the friction surface.
- the elements can be the input part and the output part.
- the thickened end is formed with an arcuate contour. This is particularly favorable at different angles due to changes in tolerances in the system to be sealed element, because a favorable contact surface is available for different angles. It is also expedient if the friction ring has depressions introduced on its friction surface. This can save material.
- the object of the friction ring is achieved by a friction ring with the features of claim 7.
- An embodiment provides a friction ring, in particular for use in a torsional vibration damper, wherein the friction ring has a body and a friction surface, wherein the arm protrudes from the body, which serves to act on an element, for acting on the friction surface against a complementary friction surface.
- the arm is designed with an end thickening. This serves for sealing.
- the body and the arm are made in one piece from plastic, preferably by injection molding.
- the body and the arm are made in one piece from plastic, preferably by injection molding.
- the side facing away from the friction surface of the body is arranged at an acute angle to the plane of the friction surface. As a result, a simple assembly is achieved because the friction ring can be easily performed in the desired position.
