Abstract
A bush of a swing arm of an automobile relates to an improved structure of a connecting bush of a hanger bracket swing arm of the automobile. A reinforcing sleeve (2) has a cylindrical structure and one end of the reinforcing sleeve (2) is provided with an edge (2-1) which is bent outwards; the interior and the exterior of the reinforcing sleeve (2) are enwrapped with rubber (3); the reinforcing sleeve (2) and the rubber (3) form the cylindrical structure; a front inner bush (1) of the swing arm is arranged inside the cylinder; two ends of the front inner bush (1) of the swing arm are longer than the cylinder; two elastic slots (2-2) which are through are formed on the wall of the front inner bush (1) of the swing arm; the two elastic slots (2-2) are symmetrically formed and communicated with one end of the edge (2-1) of the reinforcing sleeve (2); and blind holes (3) are formed at two ends of the rubber (3) on the inner side of the reinforcing sleeve (2). The bush of the swing arm of the automobile solves the problems that the conventional bush of the front swing arm of the automobile has bad elasticity and poor shock-absorbing effect, and thus the outer rubber is easily extruded to crack and abraded and the service life of the components cannot be ensured.
Description
Technical field
The utility model relates to the improvement structure of automobile component, and the suspension swing arm that is specifically related to automobile connects the improvement structure of lining.
Background technology
At present, the bush structure of swing arm is before the automobile, and embedded middle skeleton can satisfy the client to the requirement of lining higher stiffness; But sacrificed the elastic performance of lining simultaneously, because elasticity is not enough, damping effect is very poor; Make outer layer rubber be easy to extruding cracking and wearing and tearing, component life also can not get guaranteeing.
The utility model content
The purpose of the utility model provides a kind of automobile swing arm lining; The elasticity that the utility model has solved existing automobile front swing arm lining lining is not enough; Damping effect is very poor, makes outer layer rubber be easy to extruding cracking and wearing and tearing, and component life also can not get the problem that guarantees.
The automobile swing arm lining of the utility model is made up of inner covering before the swing arm 1, reinforcing sleeve 2 and rubber 3; Reinforcing sleeve 2 for tubular construction and an end have outside bending along 2-1, be wrapped with rubber 3 in the reinforcing sleeve 2, it is columnar structured that reinforcing sleeve 2 and rubber 3 constitute, inner covering 1 is arranged within this cylindrical shape before the swing arm, this cylinder is longer than at the two ends of inner covering 1 before the swing arm; Elastic groove 2-2 penetrating inside and outside two is arranged on reinforcing sleeve 2 walls, and two elastic groove 2-2 are symmetrically set and connect to an end at reinforcing sleeve 2 upper edge 2-1 place.
Further, the automobile swing arm lining of the utility model also has following characteristics: described have blind hole 3-1 at reinforcing sleeve 2 inboard rubber 3 two ends.
The automobile swing arm lining of the utility model behind the increase elastic groove, also can satisfy rigidity requirement, has optimized the elastic performance of lining simultaneously.When diametral load (style of work power, this power are fitfull 0 persistent oscillation up and down) when acting on lining, outer layer rubber elastic deformation at first; When power constantly increases, middle skeleton also begins elastic deformation, after the distortion; External force passes to internal layer rubber soon, and internal layer rubber also can elastic deformation; Because ectonexine rubber can both be participated in work, the deformational displacement amount of lining increases, and elastic performance strengthens; Damping effect is greatly improved, simultaneously owing to energy and deformation distribution (outer layer rubber, middle skeleton, internal layer rubber) on three zones, under this situation; Rubber can not ftracture because of receiving limit extruding; Can be because of the more sticking wearing and tearing that cause of generating heat yet, the result is existing good damping performance, can reach very long work life again.

The specific embodiment
Below in conjunction with accompanying drawing and with illustrated embodiments the utility model is done detailed explanation.
Consult Fig. 1-Fig. 5, automobile swing arm lining is made up of inner covering before the swing arm 1, reinforcing sleeve 2 and rubber 3; Reinforcing sleeve 2 for tubular construction and an end have outside bending along 2-1, be wrapped with rubber 3 in the reinforcing sleeve 2, it is columnar structured that reinforcing sleeve 2 and rubber 3 constitute, inner covering 1 is arranged within this cylindrical shape before the swing arm, this cylinder is longer than at the two ends of inner covering 1 before the swing arm; Elastic groove 2-2 penetrating inside and outside two is arranged on reinforcing sleeve 2 walls, and two elastic groove 2-2 are symmetrically set and connect to an end at reinforcing sleeve 2 upper edge 2-1 place.
Described have blind hole 3-1 at reinforcing sleeve 2 inboard rubber 3 two ends.
The constructional feature of the utility model:
(1) lining mainly is made up of the cylindrical shape of a cardinal principle inner covering and the reinforcing sleeve that is surrounded by rubber.
(2) swing arm inner covering cylindrical metal is positioned at the inside of reinforcing sleeve, and slightly is longer than reinforcing sleeve, relative reinforcing sleeve, and two ends slightly grow.
(3) outside of inner covering is the rubber layer that inner pincers have reinforcing sleeve, and the two-end thickness of rubber layer outside face is greater than centre portion, and the center of centre portion is drum slightly, sees similarly to be the slightly groove of drum of a center from section-drawing.
(4) reinforcing sleeve is to be processed by a kind of high-intensity metal, clamps in rubber inside, and is cylindrical, and there is an opening the outwards vertical outstanding outer that forms, the upper end of cylinder on the wall of reinforcing sleeve, and opening vertically gets off from the upper end to a certain position of centre, less than the bottom.
Above embodiment is the more preferably specific embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection domain of the utility model.
Claims (2)
1. automobile swing arm lining is made up of inner covering before the swing arm (1), reinforcing sleeve (2) and rubber (3); Reinforcing sleeve (2) has the edge (2-1) of outside bending for a tubular construction and an end; Be wrapped with rubber (3) in the reinforcing sleeve (2); Reinforcing sleeve (2) is columnar structured with rubber (3) formation, and inner covering (1) is arranged within this cylindrical shape before the swing arm, and this cylinder is longer than at the two ends of inner covering (1) before the swing arm; It is characterized in that on reinforcing sleeve (2) wall elastic groove penetrating inside and outside two (2-2) being arranged, two elastic grooves (2-2) are symmetrically set and connect to an end at place, reinforcing sleeve (2) upper edge (2-1).
