Problems solved by technology

[0003] The disadvantage of the above-mentioned thrust plate is probably that its structural strength is small and its wear is high, which leads to its short service life
In addition, due to slippage between the face of the thrust plate facing away from the clutch and the annular engagement flange of a surrounding bearing ring of the release bearing, a lot of noise is generated

Embodiment Construction

[0036] FIG. 1 shows a longitudinal sectional view of a thrust plate 1 of the present invention, corresponding to line A-A in FIG. 2 . FIG. 2 shows a view of the thrust plate 1 in the direction of the arrow "X" in FIG. 1, while FIG. 1a is a detail view of the detail "Z" of FIG.

[0037] The effect of the thrust plate 1 is to transmit the release force of the release bearing to the reed 2 of the disk spring of a shift release clutch. Neither the shift release clutch and the release bearing with disk springs are shown.

[0038] During disengagement and engagement, slippage occurs between the leaf reed 2 and a clutch-facing face 3 of the thrust disk 1 . Thus, the thrust plate wears on the contact surface of the reed 2. The contact surface is designed as a concavely curved circumferential groove 4 into which the end of the tongue 2 engages with a coaxial curvature.

[0039] Below the circumferential groove 4, there is a reinforcing rib 5, see also Fig. 1a. The reinforcing rib h...

Abstract

The invention relates to a thrust plate (1) of a release bearing of a shifting release clutch, the face (10) of the thrust plate facing away from the clutch is in pressure contact with an annular engagement flange of a surrounding bearing ring of the release bearing, the stop The face (3) of the push plate close to the clutch is in pressure contact with the reeds (2) of a disc spring, and also through the arms (7) and the webs (9) extending radially between the reeds (2) ) while being form-locked. Improvements in structural strength and wear resistance, as well as in the fixed retention and noise generation of the thrust plate (1), and in the rapid self-centering of the release bearing are achieved by the following measures: The thrust disc (1) has reinforcing ribs (5) and support arms (7), preferably made of metal, the plastic of the thrust disc (1) has a structure-enhancing and friction-reducing composition, and, at a distance from Microstructures are provided on the face (10) of the clutch and on the face of the preferably plastic-coated annular coupling flange for the rapid production of a form-locking connection between these two faces.

Description

technical field [0001] The invention relates to a release bearing of a shifting separation clutch, especially for automobiles with manual shifting or automatic shifting transmissions. Background technique [0002] In DE 34 24 227 a plastic-thrust plate of the release bearing of the shifting release clutch is described, the face of the thrust plate facing away from the clutch is in pressure contact with an annular engagement flange of a surrounding bearing ring of the release bearing, The clutch-facing side of the thrust disk is then in pressure contact with the leaves of a disk spring and is also positively locked via the arms and webs extending radially between the leaves. [0003] The disadvantage of the above-mentioned thrust plate is probably that its structural strength is small and its wear is high, which leads to its short service life. In addition, considerable noise is generated due to slipping between the face of the thrust plate facing away from the clutch and th...
