Abstract

The utility model discloses an automobile chassis bush which comprises an inner tube, an outer tube and a rubber connecting structure. The automobile chassis bush is characterized in that the outer tube is sleeved inside the inner tube coaxially, and the inner tube and the outer tube are in vulcanization connection through the rubber connecting structure. To sum up, the automobile chassis bush overcomes defects in the prior art, saves processing cost, and meanwhile, safety and reliability of the automobile chassis bush are greatly improved. The automobile chassis bush can effectively attenuate vibration of the automobile chassis generated in all kinds of working stations, and has good durability.

Description

A kind of car chassis lining

Technical field

The utility model relates to a kind of car chassis sleeve member, belongs to the vehicle chassis technology field.

Background technology

Along with developing of automobile industry, people are more and more higher in the demand of aspects such as energy-conservation, comfortable, reliability to automobile.At the guide piece (as: swing arm, back axle etc.) of suspension system, with the connection mode that hinge-point more and more adopts rubber bush that is connected of vehicle body.But there is baroque shortcoming mostly in the connection structure of existing rubber bush, and its complex procedures is unfavorable for cost control.

Summary of the invention

The purpose of this utility model provides a kind of low cost of manufacture, operation is simple and the car chassis sleeve member of superior performance.

In order to achieve the above object, the technical solution of the utility model has provided a kind of car chassis lining, comprise interior pipe, outer tube and rubber connection structure, it is characterized in that: in outer coaxial tube is sheathed on outside the pipe, vulcanizes by the rubber connection structure between interior pipe and the outer tube and be connected.

Preferably, described rubber connection structure is the diameter reduced symmetrical structure.

When a kind of car chassis sleeve member that the utility model provides is used, be installed between vehicle body and the Lower control arm, the assembly opening in the interior pipe is connected with the body bolt of automobile, outer tube is connected with the automobile Lower control arm.At automobile starting or when jolting road conditions, car chassis is by the rubber effect in the lining, the vibration that decays well and produced by car chassis.Compared to existing technology, the utlity model has following beneficial effect:

1, good dynamic rate value design can reduce in the transmission of various operating mode low bottom-disc vibrations to vehicle body by actv.; 2, the composite force that can the chassis supported swing arm of actv. produces of good static stiffness value design (diametral load, axial force, twisting resistance, rock power); 3, good weather resisting property (high temperature resistant, low temperature resistant) can make automobile normally travel under various harsies environment; 4, have fabulous tired effect, can guarantee that running car did not lose efficacy for 100,000 kilometers; 5, the difficulty of processing that reduced simple in structure; 6, reduced the design cost of car load.

In sum, a kind of car chassis sleeve member that the utility model provides has overcome the deficiencies in the prior art, safety when saving tooling cost, reliability increase greatly, the vibration that can actv. decay car chassis under various operating modes, produces, and have favorable durability.

Description of drawings

Fig. 1 is that a kind of car chassis spare lining axle provided by the invention is surveyed scheme drawing;

Fig. 2 is the bush structure scheme drawing.

The specific embodiment

For the utility model is become apparent, now with preferred embodiment, and conjunction with figs. is described in detail below.

In conjunction with Fig. 1 and Fig. 2, a kind of car chassis lining provided by the invention, pipe 1 and outer tube 3 have rubber connection structure 2 in comprising between interior pipe 1 and outer tube 3, and outer tube 3, rubber connection structure 2 and interior pipe 1 make it to link together through the sulphurization of annotating the rubber machine.Rubber connection structure 2 adopts the diameter reduced symmetrical structure, the vibration that the car chassis of can decaying well produces.

Principle of work of the present utility model is: the car chassis sleeve member links together interior pipe 1, rubber connection structure 2 and outer tube 3 by the sulphurization of annotating the rubber machine earlier, eliminates the internal stress of product then by the undergauge operation.Assemble qualified car chassis sleeve member and be installed between vehicle body and the Lower control arm, the assembly opening in the interior pipe 1 is connected with the body bolt of automobile, and outer tube 3 is connected with Lower control arm.At automobile starting or when jolting road conditions, the car chassis sleeve member is just by rubber connection structure 2 effects in the lining, the vibration that decays well and produced by automobile power assembly.

Claims

1. a car chassis lining comprises interior pipe (1), outer tube (3) and rubber connection structure (2), it is characterized in that: outer tube (3) is coaxial to be sheathed on outside the interior pipe (1), is connected by rubber connection structure (2) sulfuration between interior pipe (1) and the outer tube (3).

2. a kind of car chassis lining as claimed in claim 1 is characterized in that: described rubber connection structure (2) is the diameter reduced symmetrical structure.
