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

Embodiment Construction
[0013] The aluminum alloy rubber composite joint assembly is formed by nesting the first half joint assembly 1-1 and the second half joint assembly 2-2, the first half joint assembly 1-1 and the second half joint assembly 2-2 are composed of an inner sleeve 1 made of aluminum alloy, an outer end cover 3 made of aluminum alloy, and a natural rubber elastic body 4 injected into a cavity formed between the inner sleeve 1 and the outer end cover 3 by a rubber injection machine Composed, and the first half-joint assembly 1-1 and the second half-joint assembly 2-2 are symmetrical about the center point O of the lower end surface of the inner sleeve. The skeleton 2 is embedded in the natural rubber elastic body 4 .

The invention relates to an aluminum alloy rubber composite joint assembly, which is formed by nesting a first half joint assembly and a second half joint assembly, and both the first half joint assembly and the second half joint assembly are made of aluminum alloy The inner sleeve, the outer end cover made of aluminum alloy and the natural rubber elastic body injection-molded in the cavity formed between the inner sleeve and the outer end cover 3 by a rubber injection machine, and the first half joint assembly and the second half The joint assembly is symmetrical about the center point of the lower end surface of the inner sleeve. A further preferred solution is that a skeleton is embedded in the natural rubber elastic body. Compared with the prior art, the present invention has 1: light weight, energy saving and emission reduction, 2: central symmetry, split structure, simple processing and operation, and easy assembly 3: natural rubber formula has excellent cushioning and shock absorption, and a brand new split structure , Provides excellent cushioning shock absorption curve.
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...
