Abstract
The utility model relates to a rack bar side lining of an automobile steering gear, comprising an elastic rubber lining 1, and an exterior annular positioning slot 6 with a dirt guard is arranged on the excircle of the big end of the rubber lining 1. The exterior annular positioning slot 6 on the big end of the elastic rubber lining is broadened. The inner give-way annular groove 2 for steering the stroke of the rack bar is arranged at the inner hole on the big end of the elastic rubber lining, and a rigid strengthening sleeve tube is arranged between the exterior annular positioning slot 6 and the inner give-way annular groove 2 on the elastic rubber lining 1; one end of the rigid strengthening sleeve tube 3 is provided with the convex beading 4. The rack bar side lining is able to bear certain drawing and pressing strength intensity. The rack bar side lining and the rack bar steel pipe on the steering gear unit assemblage can be assembled once. The driving safety can be effectively guaranteed without the drop of the steering dirt guard.
Description
Technical field
The utility model relates to a kind of automobile steering device tooth bar side lining.
Background technology
As everyone knows, in adopting the automobile of rack and pinion steering gear, be contained in tooth bar side lining on the steering gear housing assembly and be by the tooth bar lateral bracket and be fixed on the front panel of car body or on the front axle body.Referring to Fig. 1, existing steering gear rack side lining 1 is the rubber bush of an elastic cylinder, and annular positioning groove 6 is arranged on its outside cylinder, in the through hole elastic cylinder is arranged.This tooth bar side lining with steering assembly on tooth bar steel pipe 7 assembling the time, because assembling herein is not in place, tooth bar side lining that does not match originally and the assembly error that turns to dust boot 9 heads, clip 8 have been increased, so it turns to dust boot to come off from the annular positioning groove on the tooth bar side lining outside cylinder, to water and sand are entered in the steering assembly, cause deflector hair fastener, hard steering, turn to problems such as inefficacy, this all can bring potential safety hazard to driving.
Summary of the invention
The purpose of this utility model is the deficiency at the prior art existence, a kind of automobile steering device tooth bar side lining is provided, tooth bar side lining can bear necessarily and draw, the pressure degree, make the tooth bar steel pipe assembling one-time-reach-place on its tooth bar side lining and the steering assembly, turn to dust boot can not come off, guarantee traffic safety.
The technical solution of the utility model is as follows:
A kind of automobile steering device tooth bar side lining, comprise the elastic caoutchouc lining, the outer ring positioning groove that the assembling dust boot is arranged on the cylindrical of its big end, its structural feature is: after the suitable broadening of outer ring positioning groove with the big end of elastic caoutchouc lining, the endoporus place of big end be provided with the steering rack stroke in the circular groove of stepping down.Its effect is to keep the minimum turning radius of car load constant, guarantees original maneuverability of automobile and road-holding property.And the outer ring positioning groove after the broadening has satisfied in the head embedding outer ring positioning groove that turns to dust boot, and will turn to the head of dust boot to be fastened in the outer ring positioning groove of steering gear housing tooth bar side lining, and do not influence the locating distance on steering gear rack side lining and front panel or the preceding axis body and the cornering properties of car load by clip.
The outer ring positioning groove of elastic caoutchouc lining and in step down and be provided with a rigidity reinforcing sleeve between the circular groove, an end of described rigidity reinforcing sleeve has the crimping of protrusion, the outer ring positioning groove that its role is to increase the elastic caoutchouc lining axially and radial strength.When in the outer ring positioning groove that is fastened on tooth bar side lining turn to dust boot with the steering rack axial motion time, axial tension acts on the projecting inward crimping of outer ring positioning groove by turning to dust boot, has guaranteed that the dust boot head can not come off from the outer ring positioning groove on the tooth bar side lining outside cylinder.
In the circumference of rigidity reinforcing sleeve, be evenly equipped with the fixing through hole of a plurality of sulfurations, the effect of through hole is in the elastic caoutchouc lining curing process, the rigidity reinforcing sleeve is fixed in the elastic caoutchouc lining body, makes the rigidity reinforcing sleeve in the elastic caoutchouc lining, play booster action.
The utility model is because step down in being provided with in the elastic caoutchouc lining circular groove and rigidity reinforcing sleeve, the drawing of tooth bar side lining, pressure degree have been increased, guaranteed the effective travel of original steering rack simultaneously, make the tooth bar steel pipe assembling one-time-reach-place on its tooth bar side lining and the steering assembly, changed tooth bar side lining and the assembly error that turns to dust boot.The utility model is because step down in being provided with circular groove and rigidity reinforcing sleeve, so it turns to dust boot not to be prone to loosening or comes off from the outer ring positioning groove of tooth bar side lining, both guaranteed the locating distance on original steering assembly and car body front panel or the front axle body, do not change the total kilometrage of steering rack again, so use safe and reliable.
Description of drawings
Fig. 1 is the structural representation of existing automobile steering device tooth bar side lining confined state;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the structural representation of the utility model after assembling.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to Fig. 2: a kind of automobile steering device tooth bar side lining, comprise elastic caoutchouc lining 1 and rigidity reinforcing sleeve 3, the growth of elastic caoutchouc lining 1 big end makes outer ring positioning groove 6 broadening of big end, the circular groove 2 of stepping down in big stomidium, being provided with simultaneously, rigidity reinforcing sleeve 3 be provided with protrusion crimping 4 and with elastic caoutchouc lining 1 bonding more firm through hole 5, the circular groove 2 of stepping down in described elastic caoutchouc lining 1 endoporus is provided with, also be provided with rigidity reinforcing sleeve 3 in the described elastic caoutchouc lining 1, rigidity reinforcing sleeve 3 is arranged in outer ring positioning groove 6 in the elastic caoutchouc lining 1 and the hole and steps down between the circular groove 2.
Referring to Fig. 3, elastic caoutchouc lining 1 is on the assembling tooth bar steel pipe 7, turn to the head of dust boot 9 to embed in the outer ring positioning groove 6, and be fastened on outer ring positioning groove 6 by clip 8, cooperation by the crimping 4 that protrudes can effectively prevent to turn to dust boot not come off from the outer ring positioning groove 6 of tooth bar side lining.
