Description
Technical field
The present invention relates to a kind of automobile steering device, more particularly to a kind of automobile steering gear rack support construction.
Background technology
The rack support structure of automobile steering device is a parts in car industry steering gear, and rack support set is mounted on
On shell, rack is passed through from the inside of supporting sleeve, and support construction is playing the role of Auxiliary support to rack.In the prior art, it props up
Support set axis and rack axis are coaxial, and its diameter of bore is more than rack diameter, full in the unilateral gap of rack of support construction
Circumferential direction and rack gap are all in 0.2~0.4mm.The rack support structure of this automobile steering device, has the following problems：
During motor racing, automobile vertical tremor caused by Uneven road can be such that the teeth portion wedge angle of rack is sent out with supporting sleeve
Raw to scrape, scraping the clast of generation can influence to engage ride comfort, influence rider's feel, clamping stagnation can be caused when serious.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of rack support structure of automobile steering device, including：Shell is worn
The rack being located in the shell, the supporting sleeve being fixedly mounted in the shell, the supporting sleeve are by support portion and assembly
The annular component that portion is constituted, the rack side are the flank of tooth, and the other side of the rack is semicircular pole face, the supporting sleeve
On the rack, the support portion contacts kink with the pole face, it is characterised in that：Where the inner circle of the supporting sleeve section
The center of circle is denoted as the center of circle I, and the center of circle of circle is denoted as the center of circle II, the line in the center of circle I and the center of circle II where the circular arc of the rack section
Vertical with the flank of tooth, the center of circle I is than the center of circle II close to the flank of tooth.
In assembly, rack passes through supporting sleeve, the pole face of rack to be supported on the support portion of supporting sleeve, the flank of tooth position of rack
In in the department of assembly of the supporting sleeve.Since the line in the center of circle I and the center of circle II is vertical with the flank of tooth, the center of circle I is compared
The center of circle II is close to the flank of tooth so that and the spacing of tooth top wedge angle increases in the department of assembly of supporting sleeve and rack, so as to
The tooth top wedge angle being reduced or avoided in uneven road surface traveling hour rack is scraped with support nested structure, solves to generate due to scraping
Engagement ride comfort, the problems such as clamping stagnation.
In the prior art, the supporting sleeve axis of automobile steering device is overlapped with rack axis, and diameter of bore is straight more than rack
Diameter, supporting sleeve inner circle week direction and rack gap distance all having the same, generally 0.2~0.4mm, so, in vehicle
In uneven road surface, teeth portion wedge angle may can scrape traveling with supporting sleeve.
The section circular arc institute in the center of circle and the rack where the section inner circle of the preferably described supporting sleeve annular component of the present invention
It is less than 2mm in round circle center distance, more preferable two circle center distance is 1mm.
Further, the rack support set department of assembly on can in the through groove of opening along supporting sleeve axis direction, and
The housing o type circles on the supporting sleeve.
Further, o type ring recess can be opened in the supporting sleeve circumferential lateral surface, and the o types circle is mounted in o type ring recess
It is interior.
Still further, boss can also be set on the outside of the supporting sleeve, while setting is corresponding with boss on shell
Groove.
Certainly, the boss on supporting sleeve can make unidirectional protrusion.
Automobile steering gear rack support construction provided by the invention makes supporting sleeve assembled portion and rack teeth wedge angle
Spacing rationally increases, to effectively prevent being scraped with supporting sleeve in the teeth portion wedge angle of uneven road surface traveling hour rack.
