Technical Field

The invention relates to the technical field of automobile accessories, in particular to a high-durability chassis dynamic vibration absorber system with limiting protection.

Background

The existing dynamic vibration absorber is usually a structure with a mass block exposed outside and a metal vulcanization molding structure, an internal rubber damping system of the existing dynamic vibration absorber can be stretched infinitely under the extreme working condition, the durability of the existing dynamic vibration absorber is poor, meanwhile, the basic working principle of the dynamic vibration absorber is that the vibration of an automobile is transmitted to the mass block of the dynamic vibration absorber, the mass block needs to use ferrous metal, after the completion of a common product, the surface of the metal needs to be subjected to antiseptic treatment, the cost of the product is increased, meanwhile, in the surface treatment process, the environmental pollution is easy to generate, the surface paint layer of the antiseptic mass block is easy to damage and corrode due to the impact of silt of a chassis on a road surface, if the mass block does not have good limit protection, in the driving process of the automobile, once the mass block and the rubber damping block fail to glue, the mass block can fly out and fall off in the driving of the automobile, and can cause, forming a great accident and having great potential safety hazard.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide a high-durability anti-drop chassis dynamic vibration absorber system with limiting protection.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a high durability chassis dynamic vibration absorber system with spacing protection which characterized in that: including interior sleeve pipe, rubber subject, quality piece, installation bolt and anticreep gasket, interior sleeve pipe and rubber subject vulcanize to the inside of quality piece, the installation bolt passes anticreep gasket and interior sheathed tube one end in proper order and finally fixes on the bumper shock absorber.

Preferably, the outer diameter of the anti-dropping gasket is larger than the inner diameter of the mass block, so as to: the mass block limiting and anti-falling protection function is achieved.

The invention has the advantages that in the design of the domestic dynamic vibration absorber at present, because of no limit anti-drop device, the dynamic vibration absorber has larger displacement in actual work, the durability of the dynamic vibration absorber is lower, and the risk of failure is larger; in case the quality piece will the departure drop, has great potential safety hazard, and this patent dynamic vibration absorber design has spacing anti-drop boss, and displacement volume under the extreme condition again of control dynamic vibration absorber plays limiting displacement, the durability of the product that improves greatly, and the quality piece after anti-drop boss can the effective control became invalid can the effectual security that improves the process of traveling.

Detailed Description

The following detailed description of the preferred embodiments will be made with reference to the accompanying drawings. As shown in fig. 1-4, a high-durability chassis dynamic vibration absorber system with limit protection comprises an inner sleeve 1, a rubber body 2, a mass block 3, a mounting bolt 4 and an anti-drop gasket 5, wherein the inner sleeve 1, the rubber body 2 and the mass block 3 are integrally vulcanized and then are screwed down by the mounting bolt 4 and the limit anti-drop gasket 5 to be mounted on a vibration absorber to form a final dynamic vibration absorber system. The surface of the mass block is completely wrapped by one layer of rubber, the cost is low, the rubber layer on the surface of the mass block is difficult to damage due to the impact of the sediment on the chassis, the mass block does not need surface treatment (electrophoresis, coating and the like), the power vibration absorber with the structure can not only guarantee enough anticorrosion and durability requirements, but also can effectively prevent the mass block after failure from falling off, and therefore the durability of the power vibration absorber and the driving safety of the whole vehicle are effectively guaranteed.

Compare ordinary dynamic vibration absorber, through optimizing the back, increase spacing anticreep gasket 5 between dynamic vibration absorber and the construction bolt 4, can effectively restrict the displacement of dynamic vibration absorber under the extreme condition, the displacement volume of dynamic vibration absorber is at fixed interval A, can effectual improvement dynamic vibration absorber's high durability, if the ageing out-of-effect back anticreep gasket 5 of rubber can effectually prevent that the quality piece from droing, plays the effect of protection, promotes the security of traveling.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
