一种轮毂止退结构

Abstract

本实用新型公开了一种轮毂止退结构，包括轮毂本体，轮毂本体上沿圆周方向设置若干个供第一螺栓安装的第一通孔，轮毂本体通过第一螺栓可拆卸的安装于车轴上，车轴的外端从轮毂本体的中部内孔处露出，车轴的外端部设置装配孔，轮毂本体的外侧可拆卸的安装有止退盖，止退盖中轴设置供第二螺栓安装的第二通孔，止退盖通过第二螺栓旋于装配孔处进而与车轴安装为一体，止退盖的外围对轮毂本体进行阻挡。本实用新型通过止退盖的设置，其稳定的安装于车轴上对外围的轮毂本体进行阻挡，有效防止轮毂本体因外部因素松动后退出、脱落，能够大大提高车辆使用的安全性，保障驾驶者的人身安全，并有利于车辆和轮胎的长期使用。

Claims

1. A wheel hub anti-backoff structure, comprising a wheel hub body (1), a plurality of first through holes (11) for mounting a first bolt (2) are arranged on the wheel hub body (1) in a circumferential direction, and the wheel hub body (1) is detachably mounted on an axle (0) through the first bolt (2), characterized in that: The outer end of the axle (0) protrudes from the inner hole (12) in the middle of the hub body (1). The outer end of the axle (0) is provided with a mounting hole (01). A retaining cover (3) is detachably installed on the outer side of the hub body (1). The retaining cover (3) is provided with a second through hole (31) for the installation of a second bolt (4). The retaining cover (3) is screwed into the mounting hole (01) by the second bolt (4) and thus installed as a whole with the axle (0). The outer periphery of the retaining cover (3) blocks the hub body (1).

2. A wheel hub retention structure according to claim 1, wherein: The diameter of the anti-reverse cover (3) is adapted to the location of the first through hole (11), thereby blocking the first through hole (11) and the first bolt (2) therein.

3. A wheel hub retention structure according to claim 2, wherein: The diameter of the anti-reverse cover (3) is smaller than the outermost position of the first through hole (11), thereby exposing the first through hole (11) and the first bolt (2) for observation.

4. A hub anti-rollback structure according to claim 1, 2, or 3, characterized in that: The inner side of the anti-reverse cover (3) is provided with a limiting groove (32), and an O-ring (33) is provided at the limiting groove (32). When the anti-reverse cover (3) is installed on the axle (0) in place, the O-ring (33) abuts against the wheel hub body (1) for structural stability.

5. A wheel hub backstop according to claim 2 or 3, wherein: The first through hole (11) is evenly arranged in 4-6 on the hub body (1), and the anti-reverse cover (3) is circular, with its outer periphery evenly covering all the first through holes (11) and the first bolt (2).
