Problems solved by technology

[0002] The steering gear bushing is a key part of the steering gear positioning structure. The wear of the steering gear bushing will lead to poor positioning of the steering gear in the steering system, which will lead to insufficient steering return and reduced steering accuracy when the vehicle is driving.
In order to solve the problem of bushing wear, the general rubber sleeve provided on the outside of the steering gear bushing in the prior art has the disadvantages of being not wear-resistant, easily deformed, and not resistant to aging

Abstract

The invention discloses a rubber sleeve for a bushing of an automobile steering device. The rubber sleeve comprises raw materials in parts by weight as follows: 40-60 parts of natural rubber, 20-35 parts of butadiene styrene rubber, 20-40 parts of butadiene rubber, 0.5-3 parts of N,N'-m-phenylene dimaleimide, 0.5-1.5 parts of a vulcanization accelerator M, 1-3 parts of zinc oxide, 2-5 parts of stearic acid, 1-3 parts of epoxy acetyl methyl linoleate, 5-10 parts of carbon black, 5-15 parts of nano silicone dioxide, 40-60 parts of ceramic fiber, 20-40 parts of bentonite glass bead composite microspheres, 0.5-2.5 parts of an organosilane crosslinked polyethylene crosslinking agent, 1-3 parts of an anti-aging agent AW and 1-3 parts of an anti-aging agent RD. The rubber sleeve is wear-resistant, unlikely to deform, good in anti-aging performance and long in service life.

Description

technical field [0001] The invention relates to the technical field of rubber for steering gear bushings, in particular to a rubber sleeve for automobile steering gear bushings. Background technique [0002] The steering gear bushing is a key part of the steering gear positioning structure. The wear of the steering gear bushing will lead to poor positioning of the steering gear in the steering system, which will lead to insufficient steering alignment and reduced steering accuracy when the vehicle is driving. In order to solve the problem of bushing wear, the conventional rubber sleeves provided on the outside of the steering gear bushing have the disadvantages of not being wear-resistant, easily deformed, and not resistant to aging. SUMMARY OF THE INVENTION [0003] The invention provides a high-load-resistant steering gear bushing rubber for automobiles. The product is wear-resistant, not easily deformed, has good aging resistance and has a long service life. [0004] A...
