Technical Field

The utility model belongs to the technical field of auto-parts, a damping pad, in particular to rubber shock pad is related to.

Background

The main material of the rubber shock pad is rubber, so that the rubber shock pad has the advantage of good elasticity, and is applied between an axle and a frame of an automobile to play a role in elastic shock absorption.

For example, chinese patent literature discloses a commercial vehicle suspension rubber cushion [ application number: 2008200677854, respectively; authorization notice number: CN201225381Y ], which is composed of a connecting plate, a lower connecting plate and a vulcanized rubber composite layer, wherein the vulcanized rubber composite layer is composed of a vulcanized rubber layer and a metal layer which are arranged at intervals in an overlapping way and is positioned between the upper connecting plate and the lower connecting plate, and a central bolt and a nut connect the upper connecting plate through a middle through hole of the upper connecting plate, the lower connecting plate and the vulcanized rubber composite layer. The lower connecting plate and the rubber vulcanization composite layer are connected into a whole.

Foretell commercial car rubber shock pad passes through multilayer vulcanized rubber layer and metal level, can reduce vibrations and noise, but multilayer vulcanization processing for it is convenient inadequately to make, and the antidetonation effect is still not ideal enough moreover, and the bolt receives vibrations to influence, has not hard up problem, connects firmly inadequately.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists among the prior art, provide a damping nature good, can prevent the not hard up rubber shock pad of bolt.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a rubber shock pad, includes the bolt and is the rubber body of tube-shape, the inner wall of rubber body have the fender shoulder that supplies the bolt head to support to lean on, the pole body of bolt stretches out rubber body upper end setting, the lower extreme outer wall of rubber body the connecting seat of radial evagination has, the connecting seat connecting hole that a plurality of circumference equipartition and axial link up has, its characterized in that, the rubber body in be equipped with the elastic component of supporting bolt head, the upper end outer wall of rubber body the bulge loop that has radial evagination, the external diameter of bulge loop be less than the external diameter of connecting seat, rubber body overcoat have the silica gel cover, the upper end of silica gel cover contradict in the bulge loop, the lower extreme of silica gel cover contradicts in the connecting seat.

In the above rubber shock pad, the elastic member is a spring, an upper end of the spring abuts against a head of the bolt, and a lower end of the spring abuts against a rubber pad located in the rubber body.

As another aspect, in the above rubber shock pad, the elastic member is a cylindrical rubber column, and the rubber column is inserted into the rubber body. The rubber column plays the elastic support effect, avoids the bolt not hard up, has also improved buffering shock attenuation effect.

In the rubber shock pad, the silica gel sleeve is provided with a notch which penetrates through the silica gel sleeve in the radial direction and extends in the axial direction.

In the rubber shock pad, the silica gel sleeve is provided with a plurality of through holes which are radially penetrated.

In the rubber shock pad, the through holes are uniformly distributed at intervals in the axial direction, and each circle of through holes are uniformly distributed in the circumferential direction.

In the above rubber shock pad, the top surface of the convex ring is a conical surface. The conical surface plays a role in dispersing pressure downwards, and the damping effect of the rubber body can be improved.

Compared with the prior art, this rubber shock pad can prevent that the bolt is not hard up, and job stabilization nature is good, can play multiple buffering shock attenuation effect moreover, and whole shock attenuation nature is good, and noise at work is little.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, fig. 2 and fig. 3, this rubber shock pad includes bolt 1 and the rubber body 2 that is the tube-shape, the inner wall of rubber body 2 has the fender shoulder 3 that supplies 1 head of bolt to lean on, 2 upper ends of the body extension rubber body of bolt 1 set up, the lower extreme outer wall of rubber body 2 has radial evagination connecting seat 4, connecting seat 4 has six circumference equipartitions and the connecting hole 5 that the axial link up, be equipped with the elastic component of 1 head of supporting bolt in the rubber body 2, the upper end outer wall of rubber body 2 has radial evagination bulge loop 6, the top surface of bulge loop 6 is conical surface 61, the external diameter of bulge loop 6 is less than the external diameter of connecting seat 4, rubber body 2 overcoat has silica gel cover 7, the upper end of silica gel cover 7 is contradicted in bulge loop 6, the lower extreme of silica.

This rubber shock pad passes through the setting of elastic component, not only carry out elastic support to bolt 1, avoid bolt 1 not hard up, make 1 job stabilization of bolt, and the elastic component plays buffering cushioning effect, the shock attenuation nature has been improved, bulge loop 6 and connecting seat 4 play axial limiting displacement to silica gel cover 7 in addition, silica gel cover 7 has improved buffering cushioning effect, elastic fit silica gel cover 7 and the elastic component elasticity between them of this rubber shock pad self like this, can play multiple buffering shock attenuation effect, whole shock attenuation nature is good.

Further carefully say, elastic component is spring 8 in this embodiment, and spring 8's upper end is contradicted in 1 head of bolt, and the lower extreme of spring 8 is contradicted and is had the rubber pad 9 that is arranged in rubber body 2, and spring 8 provides elasticity and makes 1 head of bolt contradict all the time on keeping off shoulder 3, avoids 1 not hard up of bolt, also plays buffering shock attenuation effect, and rubber pad 9 plays supporting spring 8's effect, avoids 8 lower extremes of spring to take place the skew and send the noise in the course of the work.
