Abstract: A clip engages a pair of legs of a vibration attenuator to reduce the local separation of the legs, thereby increasing the force of friction pads, affixed to the legs, against a brake disk to compensate for reduced thickness of the friction pads due to wear. The clip has a first end region, which can preferably be snappably engaged with one of the legs so as to pivot thereabout. The clip has a second end region with a protrusion which can be engaged with the other leg so as to restrain it at the reduced separation. Preferably, a second protrusion is provided to allow restraining the other leg at an even smaller local separation from the leg that is rotatably engaged by the first end region. A tab preferably extends beyond the first protrusion to aid in engaging and disengaging the second end region from the other leg.

Abstract: A balancing machine with a clamping device for mounting a vehicle wheel on a balancing machine shaft. The clamping device has a mounting flange (7) with multiple recesses (13) for receiving at least one centering pin (8). To reduce centering errors and/or balancing errors because of play between the centering pin (8) and the mounting flange (7), e.g., due to manufacturing tolerances or wear, the centering pin has an elastically deformable circumference (21) which in its operating position is in contact with a wall surface (25) of the mounting flange (7) bounding the recess (13). The circumference (21) can be either hydraulically or mechanically deformable. In addition, the invention also relates to a balancing machine having a mounting flange (7) having a central opening for axial guidance on a shaft.

Abstract: A speed clamping nut to clamp the rim of a vehicle wheel on an end fitted with an outer thread of a shaft of a balancing machine, comprising a housing having at least one grip mounted in substantially radially manner to the housing, and an inside thread. A threaded component rotational about the screw axis of the speed clamping nut and relative to the housing is connected to the housing and comprises an inside thread and is connected with the drive side of a rotational drive system connected to the housing. Following engagement, the rotational drive system assumes the complex and time-consuming screwing-on procedure when the wheel rim is pulled against spring forces toward a centering cone.
