Aluminum alloy and rubber composite joint assembly

Abstract

The invention relates to an aluminum alloy and rubber composite joint assembly which is obtained through nesting a first half joint assembly and a second half joint assembly. The first half joint assembly and the second half joint assembly are respectively composed of an inner sleeve which is made of an aluminum alloy material, an outer end cover which is made of the aluminum alloy material, and a natural rubber elastomer which is formed through injection in a chamber that is formed between the inner sleeve and the outer end cover 3 by a rubber injection machine, wherein the first half joint assembly is symmetrical with the second half joint assembly relative to the central point of the lower end surface of the inner sleeve. A further preferable solution is characterized in that a frame is embedded in the natural rubber elastomer. Compared with the prior art, the aluminum alloy and rubber composite joint assembly is advantageous in that 1, small weight, energy saving and emission reduction are realized; 2, the aluminum alloy and rubber composite joint assembly has a central symmetrical and divided structure, and furthermore simple operation in machining and easy assembling are realized; and 3, the natural rubber has an excellent vibration damping performance, and an excellent vibration damping curve is generated through the novel divided structure.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an aluminum alloy rubber composite joint assembly used for connecting the thrust rods of an automobile between double axles of a truck. Background technique [0002] In the field of auto parts, especially in the field of heavy-duty auto parts, the requirements for the thrust rod are very high. The thrust rod is also called anti-roll bar, and its function is to assist the original part of the elastic part. The role played by the anti-roll bar is to prevent the car body from tilting when turning at an intersection. In layman's terms, if there is no anti-roll bar to improve the balance of the car when turning, then the word drift does not exist! The so-called F1 lane will not have so many curves. The anti-roll bar is made of high-strength and high-toughness spring steel, most of which are English letters U in shape, and are placed horizontally on the front and rear axles of the...

AI Technical Summary

Problems solved by technology

Although the automotive thrust rod joint with this structure has a certain degree of freedom in three-dimensional space, when its deformation exceeds the allowable range of polyurethane elastomer, the parts of the joint are not only easily deformed and damaged, which affects the service life, but also is resistant to deformation. Insufficient impact strength, heavy weight, not energy-saving, and cannot be directly applied to heavy trucks equipped with air suspension systems
