Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] As shown in the figure, the centering and multi-directional movement structure of the motorcycle continuously variable transmission clutch in this embodiment includes a transmission shaft 1 and a drive disc 2 sleeved on the transmission shaft and splined with the transmission shaft. And the sliding sleeve 3 that is rotatably matched with the transmission shaft and the moving wheel 4 that is sleeved on the sliding sleeve, one end of the inner hole of the moving wheel is fixedly provided with a first sliding bearing 5 and a first stop that prevents the first sliding bearing from falling off in the axial direction. Ring 6, the other end of the inner hole of the moving wheel is provided with a second sliding bearing 7 and a second retaining ring 8 to prevent the second sliding bearing from falling off in the axial direction, the first sliding bearing ...

Abstract

The invention discloses a centering multidirectional movement structure of a motorcycle steplessspeed changing clutch. The centering multidirectional movement structure comprises a transmission shaft and a driving disc, and further comprises a slide sleeve and a movable wheel arranged on the slide sleeve in a sleeving manner, wherein a first slide bearing and a first retainer ring for preventing the first slide bearing from releasing in an axial direction are fixedly arranged at one end of an inner hole of the movable wheel; a second slide bearing and a second retainer ring for preventing the second slide bearing from releasing in an axial direction are fixedly arranged at the other end of the inner hole of the movable wheel; the first slide bearing and the second slide bearing are in sliding fit with the slide sleeve. According to the centering multidirectional movement structure of the motorcycle stepless speed changing clutch, a matching structure of the slide bearings and the slide sleeve is used for replacing a previous steel wheel, slide sleeve and oil seal combined structure; the slide bearings are simple in structure and low in manufacturing cost, and have good wear resistance; the abrasion problems of a steel sleeve and the slide sleeve in the prior art can be avoided; meanwhile, the oil seal damage problem in the prior art is also eliminated and the working reliability of the clutch can be greatly improved.

Description

technical field [0001] The invention relates to a clutch, in particular to a continuously variable transmission clutch of a motorcycle. Background technique [0002] The centering multidirectional motion structure is an important structure of the motorcycle CVT clutch. It is centered by the sliding sleeve, and the moving wheel has both circumferential rotation and axial sliding on the sliding sleeve to realize the clutch CVT. [0003] In the prior art, the centering multi-directional movement structure is a combined structure of a steel sleeve, a sliding sleeve, and an oil seal. The steel sleeve is fixed on the moving wheel, the steel sleeve is set on the sliding sleeve, and grease is added between the steel sleeve and the sliding sleeve to realize the connection between the two. Sliding fit, the above technology has the following deficiencies: [0004] 1) Both the steel sleeve and the sliding sleeve are made of steel materials, and long-term use will cause serious wear and...
