Abstract
The invention relates to a self-limiting stabilization rod bushing. The cross section of the bushing is a semiellipse. A through hole is formed in the axial center of the bushing and is in interference fit with a stabilization rod. A through opening is axially formed in the wall of the through hole. The two end surfaces of the bushing respectively extend outwards in the radial direction of one arc-shaped edge to form a convex edge, and the two convex edges are parallel. One transverse end surface of the bushing is attached to the stabilization rod in a hooping mode; the through hole edge of the other transverse end surface of the bushing extends in the radial direction of the center of the through hole to form an annular flange, and the flange is closely attached to the stabilization rod. Due to the design of the flange structure on one side of the bushing and a limiting structure at the lower end of the bushing, axial movement of the bushing can be effectively limited, abnormal sounds of drifting are reduced, noise is lowered, and excessive wear of the bushing is avoided. In addition, the bushing is simple in structure and convenient to assemble.
Description
Technical field
The invention belongs to automobile suspension system technical field, be specifically related to a kind of self-limit stabilizer bar bushing.
Background technology
The Automobile shaft of independent suspension is divided into two sections, and every wheel is independently arranged on below vehicle frame with coil spring, and like this, when a sidecar wheel is subject to involving, another side wheel can not involved, and the stationarity of automobile and traveling comfort are good.Stabilizer rod is a kind of assistant spring element in automotive suspension, and automobile anti-tipping is realized by stabilizer rod assembly.Stabilizer rod assembly system is comprised of stabilizer rod, stabilizer bar arm, stabilizer bar bushing and stabilizer rod pull bar, and wherein the Main Function of stabilizer bar bushing is restricted stability bar and makes stabilizer rod and periphery part flexibly connects.
Conventional stabilizer bar bushing, mainly realizes locking by lining endoporus and stabilizer rod interference fit at present.Stabilizer rod clip is amplexiformed in the axial one end of lining, radially by bolts assemblies, produces diametral load, thereby makes rubber deformation, realizes locking effect.
This type of stabilizer bar bushing is to utilize axial force locking with rubber deformation traditional approach, stabilizer rod to be connected with stabilizer bar bushing.This type of stabilizer bar bushing has only solved stabilizer bar bushing assembly problem, and it axially fails the motion of fine restriction stabilizer bar bushing, thus make vehicle in the process of moving stabilizer bar bushing can produce play abnormal sound, affect car load NVH performance.The present invention is by head it off.
Summary of the invention
The object of this invention is to provide a kind of brand-new stabilizer bar bushing, thereby solve the axial infinite place of bushing for automobile stabilizer bar, play and produce the problem of abnormal sound.
The present invention is achieved by the following technical solutions:
A self-limit stabilizer bar bushing, the cross-sectional plane of lining is half elliptic, described lining axial centre is through hole; Described through hole and stabilizer rod are interference fit; Described through hole hole wall is axially provided with the opening of perforation;
Two end faces of described lining are respectively along the arc-shaped side chimb that extends radially outwardly out, and two chimbs are parallel; The curved surfaces of two described chimbs and described lining forms groove, and described groove coordinates with stabilizer rod upper bracket;
Horizontal end face of described lining and the laminating of stabilizer rod clip; The through hole edge of another horizontal end face is to through hole center-diameter to extending a circle flange, and described flange and stabilizer rod fit tightly.
On the bottom surface of described lining, be provided with a positive stop lug boss.
Described opening is arranged on bottom surface or arcwall face.
Useful technique effect of the present invention is:
By bush side to turnup structure and the design of lower end position limiting structure, can effectively limit lining axial motion, reduce play abnormal sound, reduced noise, avoid lining undue wear; And simple in structure, convenient for assembly.
Accompanying drawing explanation
Fig. 1 is the use view of the present embodiment stabilizer bar bushing;
Fig. 2 is the present embodiment bushing structure of stabilizer bar schematic diagram;
Fig. 3 is the present embodiment stabilizer bar bushing and support assorted front view;
Fig. 4 is the present embodiment stabilizer bar bushing and support assorted lateral plan.
The specific embodiment
By specific embodiment, describe technical scheme of the present invention below, following instance is only exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not to be interpreted as is the restriction to technical solution of the present invention.
Fig. 1 to Fig. 4 is the structural representation of the application's a specific embodiment.Self-limit stabilizer bar bushing, is quality of rubber materials, mainly by the mode of axial locking, is undertaken spacing.
Particularly, as shown in Figure 2, the self-limit stabilizer bar bushing of the present embodiment, bush body cross-sectional plane is half elliptic, comprises a curved surfaces, a bottom surface and two horizontal end faces, body axial centre is provided with through hole; This through hole was to win to coordinate with stabilizer rod; On body bottom surface, axially have the groove 304 connecting with through-hole wall.In other embodiment of the application, the groove of perforation also can be opened on curved surfaces as required.
Two horizontal end faces of lining are respectively along the arc-shaped side chimb that extends radially outwardly out, and this chimb 301 and 302, two chimbs of chimb are parallel to each other respectively; Two chimbs and curved surfaces form groove, coordinate with stabilizer rod upper bracket.
Horizontal end face of lining and the laminating of stabilizer rod clip; The through hole edge of another horizontal end face extends outward a rubber flange 303, by rubber turnup structure, stabilizer rod and lining is fitted tightly tightr.
On the bottom surface of lining, be provided with a cylindric positive stop lug boss 305, location convenient for assembly and axial limiting.By the design of position limiting structure, can limit lining axial motion by actv., reduce play abnormal sound.
The use state of lining is referring to Fig. 1, and automobile stabilizer bar assemble mechanism comprises stabilizer rod 1, stabilizer rod clip 1.1, stabilizer rod upper bracket 2, stabilizer bar bushing 3; Stabilizer rod lower bracket 4.Stabilizer rod 1 and stabilizer bar bushing 3 pre-assys.Stabilizer bar bushing 3 one end and 1.1 laminatings of stabilizer rod clip, the other end is undertaken spacing by Fig. 2 chimb 302 and flange 303.Stabilizer bar bushing lower end positive stop lug boss 305 mates with stabilizer bar arm 4.Mate with stabilizer bar arm 2 stabilizer bar bushing upper end, and upper lower bracket is by 2 bolt-lockings.
The structure design of the inner flange of stabilizer bar bushing in the application has increased stabilizer rod and lining laminating degree, has increased friction force, realizes axial limiting; The setting of Simultaneous Stabilization bar lower bracket and stabilizer bar bushing position limiting structure has prevented stabilizer bar bushing play effectively, thereby realizes stabilizer rod and lining axial locking.
This structure design is simple, and assembling easily, prevents lining play abnormal sound, and aspect reduction noise, effect is remarkable; Prevent lining undue wear simultaneously, increased the service life of lining.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is by claims and be equal to and limit.
