Description

Stabilizer bar bush

Technical Field

Background

Stabilizer bar bushing assemblies for automotive front and rear suspensions typically have a single rubber bushing mounted within a specific clip to provide rigidity to prevent the vehicle from tipping over during steering or cornering and to improve ride comfort on bumpy roads.

With the rapid development of the automotive industry, more and more system components are being developed and applied to the chassis system to meet the increasing driving demands of passengers. The stabilizer bar bushing used on the existing automobile has a simple structure, and rubber is vulcanized into a specific shape and then is matched with a hoop to be assembled on a stabilizer bar for use. The rigidity performance can be improved by increasing the rubber filling amount or adding a plastic or metal framework in the bushing. For the stabilizer bar bushing, higher radial rigidity can improve the anti-tilting performance of the automobile during steering or over-bending, and lower torsional rigidity can ensure that the automobile has better riding comfort on bumpy roads.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, a stabilizer bushing is sleeved and fixed on the periphery of a stabilizer bar by pressing a hoop on the periphery thereof, and includes a buffer structure, a support structure and a rigidity reinforcing structure, wherein the buffer structure includes a first buffer 11 capable of being clasped on the periphery of the stabilizer bar after the bushing is butted and mounted with the stabilizer bar, a second buffer 12 located outside the first buffer 11 and capable of being butted with the hoop, the reinforcing structure includes a reinforcement body 2 arranged between the first buffer 11 and the second buffer 12, the support structure includes a support body 3 embedded in the second buffer 12, the support body 3 is made of plastic, and can be replaced by metal material according to the requirement of stress.

In this example, the bushing has a first structure 100 and a second structure 200, and each of the first cushion body 11, the second cushion body 12, the reinforcement body 2, and the support body 3 includes a first portion located on the first structure 100 and a second portion located on the second structure 200.

Specifically, the cross-sectional profile of the second buffer body 12 has a circular arc edge and a straight line edge on opposite sides, and a first straight edge and a second straight edge connected between ends on both sides of the circular arc edge and the straight line edge. The overall appearance of the second buffer body 12 is redesigned, the supporting body 3 is arranged in the second buffer body, meanwhile, the requirement of mounting the stabilizer bar bushing is met,

the first and second portions of the support body 3 each comprise an arc portion and a base connected to each other. The shape of the support body 3 is kept as consistent as possible with the shape of the second buffer body 12 so as to achieve a supporting effect, the support body 3 is embedded between the inner side and the outer side of the second buffer body 12, and the extending direction and the extending length of the support body 3 are similar to those of the second buffer body 12. Namely, the length of the support body 3 embedded in the second buffer body 12 is larger than the length of the inner surface of the second buffer body 12 in the circumferential direction, the coverage range of the support body 3 is wider, and the bushing is ensured to have higher rigidity at any specific position in the radial direction, but not only in the longitudinal direction.

Further, the reinforcement body 2 is blocked between the first cushion body 11 and the second cushion body 12. The first part and the second part of the reinforcement body 2 are both semicircular, which not only plays the effect of increasing radial rigidity, but also can block between the first buffer body 11 and the second buffer body 12, and rubber of different materials is selected for use for the first buffer body 11 and the second buffer body 12 to provide a foundation for vulcanization molding, so that two types of rubber can be prevented from being mixed through separation, and two types of different rubber materials can be injected and vulcanized to complete production in common vulcanization production equipment.

In this example, the first shock absorbing body 11 and the second shock absorbing body 12 are both made of rubber, and the hardness of the first shock absorbing body 11 is lower than that of the second shock absorbing body 12. First buffer 11 can adopt natural rubber, and second buffer 12 then can adopt self-lubricating rubber (molybdenum disulfide, graphite etc. and rubber copolymerization have the effect of self-lubricating), solves the abnormal sound problem between bush and the assembly clamp.

Further, the first structural body 100 and the second structural body 200 are fixedly connected. Specifically, the first structural body 100 and the second structural body 200 are connected by fixedly connecting one end portions of the first portion and the second portion of the second cushion body 12. The first and second portions of the second cushion body 12 are integrally molded at one end thereof by vulcanization, and the first and second

structural bodies

100 and 200 are not completely separated but connected to each other at a position where they are oriented toward each other, so that they are more convenient in packaging and transportation, and the first and second

structural bodies

100 and 200 do not need to be aligned when the stabilizer bar is fitted to the inner periphery of the bushing, so that the fitting is more convenient.

To sum up, the structure of the stabilizer bar bushing of the present invention is redesigned by the bushing, and the supporting body is embedded inside the second buffer body, so that the stress structure of the bushing is changed, that is, the supporting body extends and covers in the whole circumferential direction of the bushing, thereby not only improving the longitudinal radial rigidity, but also improving the transverse radial rigidity; in addition, the supporter is built-in, has avoided the contact of clamp with the supporter, and the clamp chucking is in the periphery of second buffer, and the two is difficult for producing relative slip for structural stability after the bush installation is stronger.

The present invention has been described in detail, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the same, and the protection scope of the present invention should not be limited thereby, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
