Embodiment Construction

[0030] exist figure 1 A first embodiment of the wear compensation device 1 according to the invention is shown partially in FIG. The wear compensation device is part of a motor vehicle clutch 2 which is not shown in detail. There is a drive spring 3 . The drive spring 3 is used to drive the pinion 4 .

[0031] A special nut 5 is riveted into the drive spring 3 . A threaded pin 6 in the form of a headless screw is screwed centrally into the special nut 5 . Here, the special nut 5 has an internal thread 7 . The threaded pin 6 has an external thread 8 . The internal thread 7 is formed by a threaded side wall, just as the external thread 8 is formed by a threaded side wall. The threaded side walls of the two components fit together in the lower part 9 of the special nut 5 and form a threaded connection 10 . Above the lower part 9 , the special nut 5 has an upper part 11 which is not provided with an internal thread 7 , but on the outside realizes a side engagement 12 .

Abstract

The invention relates to a wear compensation device (1) for a motor vehicle clutch (2), which has a drive spring (3), which is provided for driving a pinion (4), wherein via the pinion (4) able to cause a wear-compensating rotational movement of the adjusting ring (15) with a slope, wherein a special nut (5) is fixedly mounted with the drive spring, inside which a threaded pin (6) for adjusting the distance is screwed In this case, a threaded connection (10) is present between the special nut (5) and the threaded pin (6), wherein at least one section of the threaded connection (10) is mechanically deformed. The invention also relates to a clutch having a wear compensation device ( 1 ) according to the invention and to a method for assembling the wear compensation device ( 1 ) according to the invention.

Description

technical field [0001] The invention relates to a wear compensation device for a motor vehicle clutch, for example of the type of a wear compensation device adjusted according to travel compensation, as it can be used in a travel adjusted clutch (TAC). The wear compensating device is provided with a drive spring, which is provided for driving a pinion, wherein a wear-compensating rotational movement of the adjusting ring with a ramp can be initiated via the pinion, wherein a special A nut, into which a distance-adjusting / maintaining threaded pin is screwed, for example in the form of a headless screw, wherein a threaded connection is present between the special nut and the threaded pin. Background technique [0002] Friction clutches and wear compensation devices / wear compensation adjustment devices are known from the prior art. For example, WO 2009 / 056092 A1 discloses a friction clutch having at least one clutch housing with a pressure plate thereon which is fixed in rotat...
