Problems solved by technology

[0003] The performance of the rubber components of the damping ring of the steering gear directly affects the service life of the steering gear, and the current rubber components of the damping ring of the steering gear have a short service life, and due to poor dynamic performance, the steering gear produces large vibrations and Noise affects the comfort and service life of the vehicle
The reason for the above problems is that the automobile steering gear bears a large load and high temperature, and the rubber components currently used for the shock absorber ring of the automobile steering gear are insufficient in strength and wear resistance, and the deformation is relatively large.

Abstract

The invention discloses a shock ring rubber assembly for an EPS electronic power steering engine and a preparation method thereof. The shock ring rubber assembly for EPS electronic power steering engine includes the following components by weight: 80-120 parts of nitrile rubber, 90-110 parts of carbon black, 8-12 parts of an ester plasticizer, 4-6 parts of indirect method zinc oxide, 1-3 parts of a quinoline rubber antioxidant, 1-3 parts of a lubricant, 1-2 parts of a promoter and 2-3 parts of a vulcanizing agent DCP. Compared with the prior art, the invention improves the wear resistance and metal bonding performance of the shock ring rubber assembly of the EPS electronic power steering engine, and solves the technical problems of rubber wearing and adverse bonding under high temperature and high load, and provides a safe and reliable security for long time operation of the EPS electronic power steering engine.

Description

technical field [0001] The invention belongs to the technical field of automobile steering gears, and relates to an EPS electronic power steering gear damping ring rubber component, and also relates to a preparation method of the EPS electronic power steering gear damping ring rubber component. Background technique [0002] With the progress of society and the improvement of people's living standards, people's requirements for the comfort of cars are getting higher and higher. When the steering wheel of the traditional steering wheel reaches the end point, the rigid collision between the pull rod and the gearbox cover will generate noise. At the same time, the steering gear components Cause damage and affect the comfort of the vehicle and the service life of the steering gear. In order to avoid this risk, the EPS electronic power steering machine adds a shock absorber ring between the tie rod and the gearbox cover. Its function is to reduce the force transmitted through the ...
