Abstract

本实用新型公开了一种防尘摩托车减震器，包括减震器和防尘套，减震器由缸体、活塞杆、弹簧及安装板组成，防尘套套设于减震器外。防尘套外表面沿轴向一体成型有多个环向凸缘，凸缘在未受力时呈外凸分布，在减震器压缩时随防尘套弹性收缩而进一步外鼓，回弹时恢复原状，使防尘套表面在往复运动中形成周期性形态变化，避免形成积尘凹槽并促使附着杂质脱落。防尘套的压缩幅度与弹簧压缩幅度相匹配，实现同步伸缩，保证防护的连续性和稳定性。

Claims

1. A dustproof motorcycle shock absorber characterized by comprising: include: The shock absorber includes a cylinder and a piston rod, with a spring sleeved around the outer periphery of the piston rod and a mounting plate fixed at its lower end; A dust cover is fitted over the shock absorber. The outer surface of the dust cover is integrally formed with multiple circumferential flanges spaced along the axial direction. The circumferential flanges are distributed outwardly on the shock absorber. When compressed, the circumferential flanges bulge outward further under elastic contraction and return to their original shape when the spring rebounds. The outer surface of the dust cover exhibits periodic morphological changes during reciprocating motion. The compression range of the dust cover matches the compression range of the spring, and they extend and retract synchronously together with the spring.

2. The dustproof motorcycle shock absorber according to claim 1, characterized in that, The root of the circumferential flange is provided with a flexible transition area, which is composed of an arc transition section.

3. The dustproof motorcycle shock absorber according to claim 1, characterized in that, The dust cover has an internal thread at its upper end, and the shock absorber has a corresponding threaded section at its upper end that matches the internal thread.

4. The dustproof motorcycle shock absorber according to claim 3, characterized in that The dust cover has a base plate at its lower end, and the base plate and the dust cover are integrally formed; the mounting plate has threaded holes, and the base plate and the mounting plate are fixed by threaded connection.

5. The dustproof motorcycle shock absorber according to claim 4, characterized in that A sealant layer is provided between the base plate and the mounting plate.
