Embodiment Construction

[0010] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0011] like figure 1 , figure 2 The automobile suspension rubber bushing shown includes a metal cylindrical inner bushing 4, the inner bushing 4 is covered with a rubber outer bushing 5, and the lower end of the outer bushing 5 has a flange 1, and some bushings A circle of mounting holes is provided on the flange of the sleeve. Outer bushing 5 has a groove 6 from top to bottom. The outside of the outer bush 5 is provided with a spiral groove 3 that goes around the outer bush 5 obliquely downward from the upper end to the upper end of the flange 1. A spring 2 is arranged in the spiral groove 3, and a protruding part of the spring 2 is in the spiral groove 3. outside. When installing and removing the bushing, the spring 3 can be easily installed and removed through the spiral groove 3, which is very labor-saving and the efficiency is greatly imp...

Abstract

The invention discloses a rubber bushing of an automobile suspension and relates to the technical field of automobile part manufacturing. The rubber bushing comprises a metallic cylindrical inner bushing, wherein a rubber outer bushing is mounted outside the inner bushing in a sleeving way; a flange is arranged at the lower end of the outer bushing; a groove is formed in the outer bushing from top to bottom; a spiral groove which is inclined downwards to surround the outer bushing for a circle is formed from the upper end of the exterior of the outer bushing to the upper end of the flange; a spring is arranged in the spiral groove. Compared with the prior art, the rubber bushing of the automobile suspension has the advantage that the problems that an existing rubber bushing of the automobile suspension is inconvenient to mount and the pre-tightening force is insufficient can be solved.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a rubber bush used for an auto suspension. Background technique [0002] The rubber bushing on the existing automobile suspension generally includes a metal cylindrical inner bushing, and the outer bushing of the inner bushing is covered with a rubber outer bushing. There is a groove at the bottom, and a plurality of axial grooves are arranged on the outer side of the outer bush, so that a steel ring is installed on each axial groove to enhance the axial preload. With this structure, when installing the bushing, the steel ring needs to enter from one end of the bushing, and the diameter of the end of the bushing is larger than the diameter of the steel ring, so it is necessary to use tools to compress the bushing and make the steel ring outward, which is very difficult to operate. It is troublesome and laborious, and the installation is very inconvenient, and th...
