Abstract
The invention discloses a kind of structure of automobile steering gear rack support set, including limited block, rack support set is semicircle cylinder, the semicircle cylinder of rack is slidably supported on the hole wall of this semicircle cylinder, setting the semicircular rings provided with major diameter on the semicircle cylinder in limited block one end, this major diameter semicircular rings upper shed, the stepped hole of the major diameter semicircular rings and housing matches, provided with two parallel annular grooves on the side face of the semicircular rings, herein before the semicircle barrel between parallel annular groove, the prominent body of an arc is respectively provided with the face of posterior end, the two ends of O-ring are wound on above-mentioned two body of dashing forward and are placed in two parallel annular grooves and form elastomer.The present invention has the advantages that not scratch support set, does not produce abnormal sound and rack with supporting the gap of inner room not increase compared with the prior art.
Description
Technical field
The present invention relates to a kind of Automotive Steering Technology, particularly a kind of structure of automobile steering gear rack support set.
Background technology：
Existing steering gear rack support set is cylindrical shape, in vehicle traveling process, and the teeth portion of rack can be produced to support set scrapes
Wound, scrapes the metal fillings produced and produces influence to engagement, or even make clamping stagnation；Due to being that rigidity connects between rack, support set and housing
Connect, abnormal sound noise is produced after gap increases；This rigid connection structure, wearing clearance can be gradually increased, it is impossible to eliminate gap,
Cause steering gear service life reduction.
The content of the invention
Abnormal sound and rack and support are not produced it is an object of the invention to provide a kind of teeth portion not scratch support set of rack, steering gear
A kind of structure for automobile steering gear rack support set that the gap of inner room will not increase.
The technical scheme is that, including limited block, it is characterised in that：Rack support set is semicircle cylinder, rack
Semicircle cylinder is slidably supported on the hole wall of this semicircle cylinder, and the half of major diameter is provided with the semicircle cylinder in limited block one end setting
The stepped hole of circular rings, this major diameter semicircular rings upper shed, the major diameter semicircular rings and housing matches, in the semicircle
The side face of shape ring is provided with two parallel annular grooves, and the semicircle barrel between parallel annular groove is forward and backward herein
The prominent body of an arc is respectively provided with lower surface, the two ends of O-ring are wound on the prominent body of above-mentioned two and are placed in two parallel annulars
Elastomer is formed in groove.
The present invention has not scratch support set, does not produce the gap of abnormal sound and rack and support inner room compared with the prior art
The advantage not increased.
Brief description of the drawings
Fig. 1 is the front view of rack support set of the present invention；Fig. 2 is Fig. 1 left view；Fig. 3 is parallel at two with O-ring
The elastomer structure figure formed in groove；Fig. 4 is the schematic perspective view that elastomer is connected with support set.
Embodiment
In order to overcome the shortcomings of the prior art, the present invention is using technical scheme as Figure 1-3, in order to solve
Scratch of the tooth of rack to support set, using the support set of semicircle cylinder, the semicylinder sliding support of rack is semicircle herein
On the hole wall of cylinder, one end of semicircle cylinder is provided with the semicircular rings 4 of major diameter herein, and the teeth portion of rack does not connect with this semicircular ring
Touch, when rack is moved, i.e., in the absence of to support set scratch, in order to solve the rotation of support set in the housing, at semicircle cylinder end
Set on the outer peripheral face of head and the slippery limited block 1 of axial groove in housing hole face, this major diameter semicircular rings and shell ends
The stepped hole of head matches, this major diameter semicircular ring lower openings, in order to which the gap for eliminating rack and support set increases because of abrasion
The abnormal sound problem of generation, on the side face of semicircle cylinder set two parallel semi-annular slots 2, this two semi-annular slots it
Between forward and backward barrel lower surface on respectively set an arc dash forward body 3, above-mentioned barrel two is respectively fitted over the two ends of an O-ring
Formation spring shape body 5 in annular groove is placed in after on the prominent body at end（Referring to Fig. 3）.
The installation and operation principle of the present invention is after O-ring is placed in the annular of support set first, manually to make major diameter
The axial notch on spacing block alignment housing bore face is set to push it in housing bore after split ring closure.Because of rack and support inner room
Gap increase when, split ring, which can reduce, to be returned to the gap of rack and support inner room original state therefore will not to produce abnormal sound, by
There is deformation when elastomer is in assembling, thus, elastomer still has certain deformation, can guarantee that the fixation between support set and housing
Connection.
