The invention relates to a clutch release bearing (21) that is in contact with a disk spring. Said clutch release bearing (21) comprises at least one curved stop face (12, 28, 30, 33) that is located at a radial distance from the axis of rotation (4) of the clutch release bearing (21) and is used for stopping at least one end (39) of at least one spring tongue (40) of the disk spring.
Description
Clutch release bearing in contact with disc springs technical field The invention relates to a clutch release bearing in contact with a disc spring. Background technique DE3743853A1 describes a clutch release bearing of this type. Either on the inner ring of the clutch release bearing, or form the thrust surface on the outer ring. The ends of the spring tongues are all in contact with the thrust surface. The thrust surface is either an annular surface around the axis of rotation, or a plurality of segmental thrust surfaces adjoining one another along the circumferential side are formed on the clutch release bearing. If a plurality of segmented contact surfaces are formed on the clutch release bearing, as described in DE 3743853 A1, for example, ribs which can engage between the spring tongues are arranged between these contact surfaces. When the clutch is disengaged, the thrust surface on the release bearing ring is pressed towards the spring tongues, causing the sprin...
