Embodiment

For making the technical problems to be solved in the utility model, technological scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.

The utility model is large at rubber hardness for existing beam, mounting hole hour is installed a hard problem, and a kind of automobile shock-absorber is provided.

As shown in Figure 1 to Figure 3, a kind of automobile shock-absorber that the utility model embodiment provides comprises the sheathed beam of being made by rubber on steel bushing 3, the described steel bushing 3, and described beam is comprised of upper beam 1 and the lower beam 2 that mutual clamping is integrated.

Described upper beam 1 and lower beam 2 include annulus pad 9 and some card columns section 10, and this some card columns section 10 is distributed on the annulus pad 9, and have projection in the some card columns section 10; Such as Fig. 5, shown in Figure 6, described steel bushing 3 comprises the first continuous cirque body 6 and the second cirque body 7, and described lower beam 2 is installed in the second cirque body 7 upper surfaces, and described upper beam 1 is installed on the lower beam 2; The some card columns section 10 of described upper beam 1 embeds the some draw-in grooves section 11 of lower beams 2, the some card columns section 10 of described lower beam 2 embeds the some draw-in grooves section 11 of upper beam 1, and relies on the card column section projection 12 at card column section 10 edges that described upper beam 1 and lower beam 2 are connected together.

As shown in Figure 4, described card column section 10 comprises curve bath 12, and described damping device is connected on the component B that required damping connects by curve bath 12.

After described beam was installed on the steel bushing 3, its upper-end surface was higher than steel bushing 3 upper-end surfaces, made beam directly contact the vibrations position to play cushioning effect.

Such as Fig. 4, shown in Figure 7, described steel bushing 3 also comprises the projection 8 of extending from the first cirque body 6 outer ends to the side, described upper beam 1 is provided with the annular groove 13 suitable with projection 8, and projection 8 and annular groove 13 match so that beam more firmly is installed on the steel bushing 3.

During installation, first lower beam 2 is inserted in the steel bushing 3, then steel bushing 3 is inserted in the mounting hole that needs the component of damping B, thereafter upper beam 1 is connected together with lower beam 2, make the up and down firm clamping of beam by card column section projection 12.

Described steel bushing 3 comprises an endoporus, and is bolted to connection on the component A4 of required damping connection, and the aperture of steel bushing 3 can change to adapt to the bolt of different size.Because the beam upper-end surface height after installing is higher than the steel bushing upper-end surface, so beam directly contacts component A, and forms cushioning effect.Such as: during Vehicle Driving Cycle, between fuel tank and the vehicle body beam is arranged, the vibrating noise of fuel pump can be attenuated in the process of transmitting, thereby improves the comfortable energy of car load.

Embodiment 2

Upper beam 1 is identical with lower beam 2 structures, therefore can save processing cost, and enhance productivity, and reduces assembly error.

Automobile shock-absorber of the present utility model can be widely used in two bolted component of usefulness and need the position of damping, such as: fuel tank braces and vehicle body joint, air-strainer and vehicle body joint etc.The technological merit of this novel damping device is to be convenient to install, original damping device design is generally the beam integral type, large when the hardness of yielding rubber like this or mounting hole can cause installing difficulty when less than normal, not easy to operate, and this kind damping device is divided into two up and down with beam, has fundamentally solved installation question.

The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
