Description
Technical field
The present invention relates to a kind of bogie of car, more precisely, being a kind of vehicle electric power-assisted steering device gap adjusting structure.
Background technology
During electric booster steering device is formed, the gap of worm and gear directly affects steering gear performance, and gap causes greatly very much steering gear rotation is unstable easily to rock, and gap is too small and occlusion tension can be caused to be difficult to rotation or even stuck state occur.And due to the factor such as inevitable abrasion and device gap distribution of oil mass between worm and gear in actual application, it is frequently not unalterable to cause gap of worm.Traditional technology is that nut is fixed and adjusts spring depth, using pressure between spring offer worm and gear, so as to ensure that gap is stable.But there is a series of problems, such as assembly and adjustment process is cumbersome, and inside is easily dirty in application process, and the possible distortional stress of spring weakens even forfeiture in it.
The content of the invention
The present invention mainly solves the technical problem present in prior art, so as to provide a kind of vehicle electric power-assisted steering device gap adjusting structure.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of vehicle electric power-assisted steering device gap adjusting structure, it is characterized in that, described vehicle electric power-assisted steering device includes a casing with gap adjusting structure, described casing includes a worm gear passage and a worm screw passage, a worm gear is provided with described worm gear passage, a worm screw group is provided with described worm screw passage, described worm gear passage includes a cylindric channel body, the both ends of described channel body are respectively equipped with a bearing groove, the bottom of described channel body is provided with a regulating tank, described worm screw group includes a worm screw, the both ends of described worm screw are respectively equipped with a positioning ring and a bearing, the head of described worm screw is provided with a connection ratchet, the afterbody of described worm screw is provided with an elastic metallic ring, described bearing is arranged in described bearing groove, described elastic metallic ring is arranged in described regulating tank.
As preferred embodiments of the present invention, described casing is made up of aluminium alloy.
The vehicle electric power-assisted steering device gap adjusting structure of the present invention has advantages below：During use, due to substituting traditional spring using elastic metallic ring, a series of defects of existing spring are thoroughly overcome, effectively stabilize the active force between worm and gear, so as to provide more steady more longlasting stress between worm and gear, the reliability of steering gear is substantially increased.The vehicle electric power-assisted steering device gap adjusting structure is simple in construction, and positive effect, cost is cheap, practical.
