Motorcycle clutch abrasion-resisting center sleeve

Abstract

The invention discloses a motorcycle clutch abrasion-resisting center sleeve. The motorcycle clutch abrasion-resisting center sleeve is provided with a center sleeve body made of aluminum alloy. A steel internal splined sleeve is embedded in the center of the center sleeve body, the center sleeve body is provided with a friction end face matched with a friction plate, and an annular shallow grooveis formed in the outer edge, close to the center sleeve body, of the friction end face. An abrasion-resisting ring matched with the annular shallow groove in shape and size is embedded in the annularshallow groove, the abrasion-resisting ring is of a steel structure, and the end face of the abrasion-resisting ring is flush with the friction end face. The clutch center sleeve is additionally provided with the abrasion-resisting ring and the steel internal splined sleeve, and thus the degree of abrasion of the friction plate and a spindle to the center sleeve can be reduced effectively, the shock resistance of the center sleeve is greatly improved, the problems of spline abrasion and fracture are solved, the service life of the center sleeve is remarkably prolonged, and the center sleeve has the characteristics of ingenious design, simple structure, easy modification, low modification cost and the like.

Description

technical field [0001] The invention belongs to the technical field of clutches, and in particular relates to a wear-resistant center sleeve of a motorcycle clutch. Background technique [0002] The center sleeve is an important part of the motorcycle clutch. When the clutch is working, the power is output through the inner spline on the center sleeve. Therefore, the inner spline structure of the center sleeve has a great influence on the service life and performance of the clutch. [0003] In the prior art, the center sleeve of the clutch is usually made of aluminum alloy, and its internal spline structure is directly processed on the inner hole of the aluminum alloy of the center sleeve. Although the center sleeve of this structure has the advantages of simple manufacturing process and low manufacturing cost, However, due to the insufficient strength of the aluminum alloy material, the center sleeve of this structure has poor impact resistance and poor wear resistance duri...

Problems solved by technology

[0003] In the prior art, the center sleeve of the clutch is usually made of aluminum alloy, and its internal spline structure is directly processed on the inner hole of the aluminum alloy of the center sleeve. Although the center sleeve of this structure has the advantages of simple manufacturing process and low manufacturing cost, However, due to the insufficient strength of the aluminum alloy material, the center sleeve of this structure has poor impact resistance and poor wear resistance during the process of outputting high torque from the clutch, and problems such as spline wear and spline breakage often occur.

[0004] Chinese patent CN104315016A disclosed a motorcycle clutch center sleeve structure on January 28, 2015. A steel inner spline sleeve is embedded in the center sleeve body. Although the problem of spline wear and fracture has been solved, the friction of the center sleeve The end face is still in direct contact with the friction plate, which is likely to cause wear on the friction end face of the center sleeve, thereby shortening the service life of the center sleeve
