Embodiment Construction

[0014] As shown in the figure: there is a flange 3 extending radially outward in the middle of the cylinder body 9, a shift fork groove 5 is provided at one end of the cylinder body 9, and an end face 4 that can be in contact with the shift fork is arranged on the flange 3. In order to prevent serious wear of the contact end surface on the separation sleeve, the material of the separation sleeve is cast steel or ductile iron, and the part of the contact end surface of the shift fork is high-frequency quenching. It is also possible to design the contact end surface 4 to be slightly higher than the flange end surface, and set the installation surface 2 of the release bearing at the other end of the cylinder 9 close to the flange 3, and set a radial bearing at the position close to the installation surface 2. An inwardly recessed annular snap ring groove 1. Insert the circlip in the circlip groove 1 to realize the connection between the bearing and the separation sleeve. In orde...

Abstract

The invention relates to automobile parts, in particular to a release sleeve on an automobile clutch and a thermal processing method thereof. According to the design scheme provided by the present invention, there is a flange extending radially outwards in the middle of the cylinder, and a shift fork groove is provided at one end of the cylinder, and the feature is: there is a flange on the flange that can be in contact with the shift fork end face. The contact end face is slightly higher than the flange end face. A mounting surface of the release bearing is provided at the other end of the cylinder close to the flange, and an annular ring groove recessed radially inward is provided at the position close to the mounting surface. An annular flange protruding radially outward is arranged beside the annular snap ring groove. Grease injection holes are set on the cylinder body. After using the device, the structure of the automobile clutch can be made more reasonable and the service life is longer.

Description

technical field [0001] The invention relates to automobile components, in particular to an automobile clutch release sleeve and a thermal processing method thereof. Background technique [0002] The separation sleeve on the automobile clutch is the main part of the automobile clutch. Other parts in the automobile clutch are combined through the sleeve to form an organic whole and complete the predetermined function. In the prior art, this separation sleeve is mainly composed of a cylinder body and a flange 3 arranged in the middle of the cylinder body. A shift fork groove 5 is provided at one end of the cylinder body for installing a separation shift fork. The wear-resistant block, during work, the separation shift fork is close to the wear-resistant block, so the wear-resistant block becomes a wearing part. The disadvantage of this structure is that it is troublesome to manufacture, and the structure is not very reasonable, especially the wear-resistant block needs to be i...
