Problems solved by technology

However, the working environment of the bushing is harsh, and the failure consequences caused by the wear and slippage of the bushing under the frequent fatigue and durability will seriously affect the driving safety of the vehicle.
[0005] The assembly position of the existing rubber bush in the multi-link independent suspension is as follows: Figure 1-2 As shown, in the process of manufacturing verification, this structure has the following problems: it is easy to cause stress concentration, fatigue damage, and seriously affects the vehicle stability and NVH performance; the stiffness control in all directions must meet the requirements; the vulcanization process requires high

Abstract

The invention discloses a swing arm bush and a swing arm bush assembly. The swing arm bush comprises an inner lining pipe, a rubber mainspring, an outer lining pipe and a mounting hole which are sleeved with one another from inside to outside in sequence, the outer wall of the inner lining pipe abuts against the inner wall of the rubber mainspring, the outer wall of the rubber mainspring abuts against the inner wall of the outer lining pipe, a horizontal flange which horizontally extends outwards is annularly arranged at one end above the outer lining pipe, the inner wall of the upper surfaceof the flange abuts against the outer wall of the bent portion of the rubber mainspring, and the mounting hole runs through the center of the inner lining pipe from top to bottom. The swing arm bush and the swing arm bush assembly are reasonable, stable and reliable in structure, the NVH and comfort of a whole vehicle can be improved, the controllability of the whole vehicle is improved, and the weight of the whole vehicle is lowered.

Description

technical field [0001] The invention relates to the technical field of automobile swing arm bushings, in particular to a swing arm bushing. [0002] The present invention also relates to a swing arm bushing assembly composed of the above swing arm bushing. Background technique [0003] The actual rubber bushings used on cars are natural rubber that has been vulcanized and filled. The vulcanization process strengthens the strength and elasticity of the rubber, making it difficult to undergo plastic deformation and reducing the sensitivity to temperature. The filling of rubber is usually carbon black particles. The filling of carbon black particles improves the wear and tear of the molecular chains during the relative movement between the molecular chains, and enhances the dissipation of mechanical energy, so that the rubber damping properties and elastic properties are improved. enhanced. [0004] The rubber bushing has dynamic and static mechanical properties, and exhibit...
