Description

Car high-strength rubber shock absorbing bushing assembly

Technical field

The utility model belongs to automobile rubber shock absorbing bushing technical field, and in particular to car high-strength rubber shock absorbing bushing Assembly.

Background technique

With economic development, people's living standards are constantly improving, people the entirety of vehicle is required it is higher and higher, Efficient and convenient and comfortableization is increasingly pursued, damping is widely used on automobile component, is rigidly connected to from automobile is incipient Existing rubber connection or even hydraulic shock-absorption connection, cushion technique are more and more applied on automobile.

In the prior art, automobile frame rubber shock-absorbing bushing generally comprises metal shell, intermediate rubber body and inner tube three Component, three components are joined together to form complete bushing, and the shell of existing bushing, inner tube pass through phase with intermediate rubber body The circumferential surface connect links together, and such structure is easy axial abjection, and buffering effect is poor, and service life is short.

Utility model content

Technical problem to be solved in the utility model is in view of the foregoing drawbacks, to provide car high-strength rubber shock absorbing bushing Assembly, good buffer effect, axial strength are high, it is not easy to deviate from, have longer service life.

The utility model solve its technical problem the technical solution adopted is as follows:

Car high-strength rubber shock absorbing bushing assembly, including metal inner pipe, intermediate rubber layer, metal outer pipe, the gold Belong to the corresponding boss that evagination is equipped with intermediate rubber layer junction of outer wall of inner tube, boss both ends pass through the conical surface to metal inner pipe surface Transition, the length of intermediate rubber layer are greater than the length of boss, and metal inner pipe lower surface is equipped with into intermediate rubber layer extension Ring, metal outer pipe inner wall are equipped with multiple inwardly projecting convex teeth, and convex tooth is uniformly distributed along axial direction, and convex dental inlay enters in intermediate rubber layer Portion, the top of metal inner pipe are equipped with retaining ring, and the upper surface of retaining ring and intermediate rubber layer is equipped with spacing, and intermediate rubber layer upper surface is The conical surface, the colloid on intermediate rubber layer top cover the metal outer pipe surface at spacing.

Further, the bottom face of intermediate rubber layer is inverted cone surface, and the lower part colloid of intermediate rubber layer covers metal outer pipe The pipe shaft of lower part.

Further, the convex tooth is ring-type.

Further, the outer wall of the metal outer pipe is equipped with plastic wrapper.

The beneficial effects of the utility model are: using the above scheme, reinforcing intermediate rubber layer and metal by boss, convex tooth Bonding strength between inner tube, metal outer pipe effectively prevents axial abjection, and the buffering effectiveness, the structure that improve bushing are strong Degree, extends the service life of bushing.

Detailed description of the invention

Through the following detailed description taken in conjunction with the accompanying drawings, the utility model objects, features and advantages above-mentioned and other will It becomes apparent.

Fig. 1 is a kind of vertical section structure schematic diagram of embodiment of the utility model.

Wherein: 1 is metal inner pipe, and 11 be boss, and 2 be intermediate buffer layer, and 3 be metal outer pipe, and 31 be convex tooth, and 4 be retaining ring, 5 be plastic wrapper.

Specific embodiment

The utility model is described further with reference to the accompanying drawing.

Referring to Fig.1, car high-strength rubber shock absorbing bushing assembly, including metal inner pipe 1, intermediate rubber layer 2, metal outer pipe 3, the corresponding boss 11 that evagination is equipped with the junction of intermediate rubber layer 2 of the outer wall of metal inner pipe 1,11 upper and lower ends of boss pass through To the surface transition of metal inner pipe 1, the setting that the length of intermediate rubber layer 2 is greater than the length boss 11 of boss 11 increases the conical surface The contact area of intermediate rubber layer and inner tube strengthens the bonding strength of intermediate rubber layer and metal inner pipe, and stress surface increases, convex The conical surface transition at 11 both ends of platform can promote the power of metal inner pipe quickly to transmit to intermediate rubber layer, can promote stress load to The circumferential, axial of intermediate rubber layer is decomposed, and improves buffering effect, while avoiding intermediate rubber layer single load bearing, improves buffering effect Fruit extends the service life of intermediate buffer layer, and the lower surface of metal inner pipe 1 is equipped with the inner ring 12 extended to intermediate rubber layer, Inner ring 12 reinforces connection, cooperates with boss, prevents axial abjection, improve the structural strength of bushing, the inner wall of metal outer pipe 3 is set There is the convex tooth 31 of multiple circular lamps being uniformly distributed circumferentially, convex tooth 31 is embedded in the inside of intermediate rubber layer 2, and the top and bottom of convex tooth are Inclined-plane, convex tooth reinforce the connection of metal outer pipe and intermediate buffer layer, avoid, while improving cushion performance, make metal outer pipe Load stress spread to intermediate buffer layer, the top of metal inner pipe 1 is equipped with retaining ring 4, and retaining ring 4 is upper with intermediate rubber layer 2 End face is equipped with spacing, and retaining ring 4 is used for positioning when installing, and quickly location and installation bushing, simplified assembly difficulty can improve bushing Using effect, the upper surface of intermediate rubber layer 2 is the conical surface, the metal outer pipe 1 at the colloid covering spacing of intermediate rubber layer 2 Surface, the bottom face of intermediate rubber layer 2 are inverted cone surface, and the lower part colloid of intermediate rubber layer 2 covers the pipe shaft of metal outer pipe lower part, On the one hand pipe shaft is capped to reinforce bonding strength, on the other hand improve the oxidation resistance of inner tube, and end face is the conical surface, inverted cone surface, The bonding strength of intermediate buffer layer 2 Yu metal inner pipe 1 is strengthened, the structural strength of bushing is high, and cushion performance is good, effective to place Axial abjection, greatly extends service life, and the outer wall of metal outer pipe 3 is equipped with plastic wrapper 5, plastic wrapper 5 for plus Strong structure intensity improves the service performance of bushing.

The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model System, it is all according to any simple modification to the above embodiments in the technical essence of the utility model, equivalent variations, fall Enter within the protection scope of the utility model.
