Abstract
The utility model relates to an elastic rack bush which comprises a bush circular ring body. Axial teeth are arranged on the outer wall of the bush circular ring body, two parallel annular grooves are formed in the axial teeth, and annular springs are arranged in the annular grooves. The elastic rack bush can eliminate abnormal sound generated in a gap of a rack and the bush body, and prolong the service life of products.
Description
Technical field
The utility model relates to a kind of elastic rack lining, in the automobile steering device parts, to reduce wearing clearance and the abnormal sound between steering rack and lining, enhances product performance, and belongs to a kind of auto parts and components.
Background technology
Tooth bar and hub sections in automobile steering device mostly adopts tooth bar and lining form at present, tooth bar and lining adopt less interference fit to reach and eliminate tooth bar and the effect of lining gap, but the tooth bar of this kind of form and lining position are due to wearing and tearing between tooth bar and lining and can not get good lubricating, make to produce wearing clearance between tooth bar and lining, along with extending gap, wearing in period can progressively strengthen the generation abnormal sound, need to change in time, so affected product design and the service life of steering box.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of elastic rack lining, and this elastic rack lining is not only eliminated tooth bar and lining gap and the abnormal sound that produces, and the service life that can improve product.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of elastic rack lining, comprise the lining torus, and be provided with axial tooth on lining torus outer wall, be provided with the parallel annular groove of twice on axial tooth, be provided with annular spring in annular groove.
The toric interior wall circular of described lining is evenly equipped with boss, and boss is provided with several well-distributed ball-type grooves.
This elastic rack lining adopts annular groove and the spring structure arranged on the lining torus, make between rack bush and tooth bar to keep certain gap, when producing gap, rack bush wearing and tearing hour rack lining and tooth bar friction eliminate wearing clearance by the elastic force of spring, thus the service life of raising product.
Be provided with boss and ball-type groove at the toric inwall of lining, can in the ball-type groove, can store certain grease, lubricating effect for the use procedure of elastic rack lining, the abnormal sound that reduces wearing and tearing between tooth bar and lining and produce because of tooth bar and lining friction, can significantly reduce the wearing clearance between tooth bar and lining, keep the lining lubricant effect, the elastic rack lining effectively reduces gap and the fricative abnormal sound of tooth bar and lining generation.
The accompanying drawing explanation
The block diagram that Fig. 1 is the elastic rack lining.
The cutaway view that Fig. 2 is the elastic rack lining.
the specific embodiment
As depicted in figs. 1 and 2, a kind of elastic rack lining, comprise lining torus 1, on lining torus 1 outer wall, is provided with axial tooth 2, is provided with the parallel annular groove of twice 5 on axial tooth 2, is provided with annular spring 6 in annular groove 5; The interior wall circular of described lining torus 1 is evenly equipped with boss 3, and boss 3 is provided with several well-distributed ball-type grooves 4.
The elastic rack lining is when work, rack surface and three boss uniform contact of spring rack bush inwall, after three boss wearing and tearing of elastic rack lining inwall, tooth bar and spring rack bush produce gap, the gap that the spring-compressed lining torus auto-compensation of spring rack bush produces because of wearing and tearing, eliminated between tooth bar and spring rack bush and caused the deflector abnormal sound because wearing and tearing produce gap, can keep in the interstice coverage of tooth bar and the requirement of spring rack bush by the auto-compensation wearing clearance.
