Clutch release bearing

Abstract

Clutch release bearing in contact with spring tongues (2, 3, 4) of a cup spring via a check plate (10, 24), wherein fins distributed on the periphery of the check plate positively engage in slits (7, 23) in the spring tongues (2, 3, 4) on the periphery directly adjacent to one another, wherein a motion clearance is provided between each fin (8, 25) positively engaging in one of the slits (7, 23) and at least one of the spring tongues (2, 3, 4) on the periphery opposite one another (7, 23), at least in the peripheral direction, by which the fin (8, 25) has limited mobility in the slit (7, 23) between the spring tongues (2, 3, 4) opposite one another.

Description

technical field [0001] The invention relates to a clutch release lever bearing which is in contact with the spring tongues of a diaphragm spring by means of a stop disc, wherein ribs distributed on the circumference of the stop disc engage in a form-fitting manner along the circumference and directly into each other. In the radial gap between adjacent spring tongues. Background technique [0002] The positive fit between the clutch disk and the spring tongues of the diaphragm spring prevents a relative movement between the spring tongue and the disk about the axis of rotation directed in the circumferential direction and thus prevents the diaphragm spring from being disengaged from the clutch The rod bearing acts to slide between the bearing rings on the diaphragm spring. [0003] Slippage occurs especially in clutches of commercial vehicles in the contact between the diaphragm spring and the paddle, if the paddle is made of plastic. In particular in the case of self-cente...

AI Technical Summary

Problems solved by technology

Said coercive forces lead to the inability to avoid noise and premature wear on the desired circumference as well as partial snapping off of the diaphragm spring tongues and thus to premature failure
