Definitions
- the invention relates to a Kupplungsausr ⁇ cklager in contact with a plate spring, wherein the clutch release bearing has at least one curved and radially to the axis of rotation of the clutch release bearing spaced starting surface for the start of at least one end of at least one spring tongue of the plate spring.
- a clutch release bearing of the generic type describes DE 37 438 53 A1.
- the contact surface is formed either on an inner ring or on an outer ring of the clutch release bearing.
- the ends of the spring tongues are in touching contact with the contact surface.
- the contact surface is either an annular surface extending around the axis of rotation.
- a plurality of contact surfaces which are segment-like and circumferentially adjacent to one another are formed on the clutch release bearing. If several of the segment-like contact surfaces are formed on the clutch release bearing, as described in DE 37 438 53 A1, for example, see ribs between the contact surfaces for engagement between the spring tongues provided.
- the circumferential contact surface on the bearing ring of the release bearing is pressed with force on the spring tongue (s), the spring tongues thereby spring axially.
- the contact on which the spring tongues meet the contact surface shifts during compression and rebound on the contact surface radially inwardly in the direction of the axis of rotation of the release bearing or radially away from the axis of rotation. The contact also shifts with increasing wear in the coupling.
- Figure 1 shows schematically the contact and contact conditions during contact of a spring tongue to Ausgurlageran extract, as described in EP 015 383 5A1.
- a curved contact surface a part of a lateral surface of a toroidal body 1 is considered by way of example.
- the toroidal Body 1 is shown in simplified form by grid lines 2 and 3.
- the axial bulge of the contact surface is symbolized by the grid lines 2.
- the grid lines 2 extend in planes in which the axis of rotation 4 extends and which are rectified with the axis of rotation 4.
- Circumferential curvatures of the contact surface in planes which are pierced perpendicularly by the axis of rotation 4 are symbolized by the grid lines 3.
- the contact surface of the non-curved end of a spring tongue is symbolized by the surface 5.
- the generating line marked with 3.1 symbolizes the axial line 3.1 of the contact surface which projects axially the most.
- the surface line 3.1 marks the reversal point (vertex) of a curvature described in the longitudinal section through one of the grid lines 2.
- the contact of the surface 5 with the surface line 3.1 at the apex of the curvature results in an optimal line contact 6.
- the line described by the line contact 6 is shown in Figure 1 the course of the surface line 3.1 corresponding curved. If the surface 5 runs tilted in the direction of the arrow 7 on the contact surface, finally results in the contacts 8 and 9, a two-point contact. As surface 5 tilts in the direction of arrow 10 on the start-up surface, the line contact becomes progressively smaller as long as surface 5 and the abutment surface are finally in point 11 in single-point contact.

- Each of the generating lines runs tangentially and rectilinearly in each case to an imaginary circle located in one of the planes.
- the axis of rotation of the clutch release bearing pierces the circle at the center of the circle vertically.
