Abstract
The utility model relates to a highly wear-resisting rack bushing of a steering gear, belonging to the technical field of manufacturing of accessories of steering gears. The highly wear-resisting rack bushing comprises a bushing body, porous grooves, axial strip-shaped raised planes and limit bosses, wherein the porous grooves and three axial strip-shaped raised planes are uniformly made on the inner wall of the bushing body, and three limit bosses are arranged on the outer edge of the bushing body. According to the highly wear-resisting rack bushing of the steering gear, a plurality of porous grooves and the three axial strip-shaped raised planes are made on the inner wall of the bushing body, and the three limit bosses are arranged on the outer edge of the bushing body, therefore normal wear of the bushing is greatly reduced, and clearances generated by bushing wearing can be automatically compensated; in addition, the highly wear-resisting rack bushing has a simple structure and solves the problems of abnormal sound of the steering gear and possibility of overquick centering of a steering wheel caused by incapability of automatic compensation after the traditional bushing is worn to generate clearances.
Description
Technical field
The utility model relates to a kind of deflector high abrasion rack bush, belongs to deflector spare parts manufacture technical field.
Background technology
What the tooth bar great majority on the automobile steering device used at present is the tubular lining of soft material; Tooth bar and lining friction for a long time are easy to liner wear; Make the bigger gap of formation between lining and tooth bar, cause the deflector abnormal sound, and just too fast phenomenon possibly appear back in bearing circle; Be unfavorable for chaufeur control bearing circle, have serious traffic safety hidden danger.
Summary of the invention
The purpose of the utility model is, provides a kind of and is manufactured with positive stop lug boss in the body outer rim, and its inwall is manufactured with a plurality of poroid grooves (being used to store grease), three axial strip convex plane of body inner wall even distribution plane; Make it have high-wearing feature, the wearing clearance that produces between ability automatic compensation tooth bar and lining.Can not automatic compensation to solve after the existing liner wear, cause deflector abnormal sound and bearing circle the deflector high abrasion rack bush of just too fast problem possibly occur back.
The utility model is realized above-mentioned purpose through following technical scheme:
This deflector high abrasion rack bush is made up of bush body, poroid groove, axial strip convex plane and positive stop lug boss; It is characterized in that: be uniformly distributed with on the bush body inwall and be manufactured with poroid groove and three axial strip convex plane, be manufactured with three positive stop lug boss on the outer rim of bush body.
The utility model beneficial effect compared with prior art is:
This deflector high abrasion rack bush is made a plurality of poroid grooves and is used to store a large amount of greases on the inwall of bush body; Be manufactured with three axial strip convex plane on the inwall simultaneously, greatly reduce the inordinate wear of lining, and the gap of ability automatic compensation liner wear generation; Be manufactured with three positive stop lug boss on the outer rim of bush body, simple and practical, simplified the position limiting structure of lining.This deflector high abrasion rack bush has solved that existing liner wear produces behind the gap can not automatic compensation, causes deflector abnormal sound, bearing circle just too fast problem possibly occur back.
Description of drawings:
Fig. 1 is a kind of front view of deflector high abrasion rack bush;
Fig. 2 is a kind of cutaway view of deflector high abrasion rack bush.
Among the figure: 1, bush body, 2, poroid groove, 3, axial strip convex plane, 4, positive stop lug boss.
The specific embodiment:
This deflector high abrasion rack bush is made up of bush body 1, poroid groove 2, axial strip convex plane 3 and positive stop lug boss 4; Be uniformly distributed with on the inwall of bush body 1 and be manufactured with poroid groove 2 and three axial strip convex plane 3, be manufactured with three positive stop lug boss 4 (referring to accompanying drawing 1～2) on the outer rim of bush body 1.
Deflector is coated with an amount of grease in the poroid groove 2 of the bush body 1 of this deflector high abrasion rack bush in fitting process, guaranteeing has enough greases in the poroid groove 2 of lining, makes lining keep for a long time lubricated.Again that other parts assemblings such as tooth bar are complete; Round degree is approximate in three axial strip convex plane that are uniformly distributed with 3 on bush body 1 inwall and the bush body 1 simultaneously; The gap that wearing and tearing produce between ability automatic compensation tooth bar and the lining makes the two remain proper fit.Be manufactured with three positive stop lug boss 4 in addition on the outer rim of bush body 1, simplified lining and outer sleeve assembled construction and played the effect of anti-rotation.
