Abstract
The utility model provides an automobile vibration damper, which belongs to the technical field of automobiles. The utility model solves the problem that the present vibration damper is lined in a sleeve and gets out easily, resulting in repeated product failures. The automobile vibration damper includes the sleeve and a bushing arranged in the sleeve and having interference fit with the sleeve, the bushing includes an inner tube and a vulcanized rubber layer arranged on an outer cylindrical surface of the inner tube, a plurality of protruded ribs are arranged on the outer surface of the vulcanized rubber layer, and a plurality of annular grooves mounted corresponding to the protruded ribs are arranged on the inner wall of the sleeve. In the automobile vibration damper, the bushing in the sleeve is not liable to get out, thereby avoiding product failures.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of automobile absorber.
Background technique
Along with advancing and rapid development of automobile industry of society, people's living standard constantly improves, and automobile has become one of a kind of important traffic tool that people ride instead of walk.Automobile absorber generally adopts hydraulic shock-absorption mechanism; The liquid storage cylinder bottom portion of damper mechanism is connected on the vehicle frame; If the liquid storage cylinder directly is connected on the vehicle frame with bolt; Because also there are vibrations in liquid storage cylinder itself, easily tie point is damaged, general solution is on connecting bolt, to install lining additional to reach the effect of secondary damping.
The liquid storage cylinder bottom portion of existing automobile absorber comprises sleeve pipe, is provided with lining in the sleeve pipe, and this lining is mainly managed the rubber layer on the external cylindrical surface by interior pipe with in being arranged on, and this interior pipe and rubber layer sulfuration are fixing, and lining is connected in the sleeve pipe through the rubber layer interference.
In above-mentioned structure, internal surface of casing and rubber layer outer surface are a plane, and the withdrawal force of lining in sleeve pipe is too small, and lining is deviate from easily in sleeve pipe and caused product to lose efficacy repeatedly.
Summary of the invention
The purpose of the utility model is to existing deficiency, and providing a kind of increases the automobile absorber of lining withdrawal force in sleeve pipe through improving sleeve pipe and vulcanized rubber layer surface of contact frictional force.
The purpose of the utility model can realize through following technical proposal: a kind of automobile absorber; Comprise sleeve pipe with place in the sleeve pipe and with the lining of its interference fit; Vulcanized rubber layer in managing in described lining comprises and placing on the pipe external cylindrical surface; The outer surface of said vulcanized rubber layer is provided with some convex tendons, and the inwall of said sleeve pipe is provided with the annular groove of some abilities and the corresponding installation of above-mentioned convex tendon.
This automobile absorber mainly is made up of sleeve pipe and lining; Frictional force through changing sleeve pipe and lining interference fit junction surface improves the withdrawal force of lining in sleeve pipe; Pipe and vulcanized rubber layer were formed in this lining had only, and be in light weight, reduced the axial pressure power of lining in sleeve pipe; During assembling, lining is installed in the sleeve pipe, the vulcanized rubber layer produces deformation, and the convex tendon of vulcanized rubber layer outer surface just in time embeds in the annular groove on the internal surface of sleeve pipe, and sleeve pipe and lining are interference fit, guarantees the join strength of sleeve pipe and lining.
In above-mentioned automobile absorber, the quantity of described convex tendon has three, has two convex tendons to be positioned at the two ends of vulcanized rubber layer, and another convex tendon is positioned at the middle part of vulcanized rubber layer.Spacing between the convex tendon at vulcanized rubber layer two ends is over half greater than vulcanized rubber layer length direction total length, guarantees the frictional force balance of vulcanized rubber layer and sleeve pipe, and the convex tendon at two ends is symmetrically distributed.
In above-mentioned automobile absorber, the described convex tendon cross section that is positioned at vulcanized rubber layer two ends is a triangle.The two triangle cross section is oppositely arranged.
In above-mentioned automobile absorber, the described convex tendon cross section that is positioned at vulcanized rubber layer middle part is square.The purpose that is provided with like this is to guarantee that the junction surface friction of vulcanized rubber layer and sleeve pipe is stressed evenly.
Compared with prior art; The outer surface of the vulcanized rubber layer of this automobile absorber is provided with some convex tendons; The inwall of sleeve pipe is provided with the annular groove of the corresponding installation with convex tendon of some abilities, and this convex tendon is connected to the frictional force that has increased sleeve pipe and vulcanized rubber layer surface of contact on the groove of internal surface of sleeve pipe, further improves the withdrawal force of lining in sleeve pipe; Lining is not easy in sleeve pipe, can not make product failure.
