Rubber suspension lining assembly structure for automobile engine

Abstract

The invention relates to a rubber suspension lining assembly structure for an automobile engine. The rubber suspension lining assembly structure comprises an outer sleeve and an inner sleeve. The rubber suspension lining assembly structure for the automobile engine is characterized by also comprising an adjustable main spring assembly, an elastic limited block and a lock piece. The adjustable main spring assembly comprises a first rubber main spring and a second rubber main spring. The elastic limited block comprises a framework at the middle and rubber cushions at two ends, wherein the framework and the rubber cushions at two ends are vulcanized into a whole body. The adjustable main spring assembly and the elastic limited block are separated from each other, rigidity adjustment and decoupling of the main spring assembly and the limited block can be realized, and better rigidity characteristics of the rubber suspension lining assembly can be obtained as required. The rubber suspension lining assembly structure for the automobile engine consists of subcomponents, modular design is performed according to different subcomponents, and the subcomponents have replaceability and generality, therefore, the development period is shortened, and the development cost is saved.

Description

technical field [0001] The invention belongs to the technical field of automobile powertrain suspension systems, and in particular relates to a rubber suspension bush assembly structure for automobile engines. Background technique [0002] With the rapid development of the automobile industry, people have higher and higher requirements on the NVH characteristics of the whole vehicle. As an important NVH component, the suspension cushion assembly is becoming more and more important, and the bushing rubber mount is widely used in automobile design because of its good reliability and low cost. The bushing rubber mount has certain requirements on stiffness, and the main factors affecting the stiffness of the mount are the main spring structure and the main spring rubber. Different main spring structures can obtain different isotropic stiffness ratios, and different main spring materials can obtain different suspension stiffnesses. The main functional part of the traditional bu...

AI Technical Summary

Problems solved by technology

The main functional part of the traditional bush-type rubber suspension - the bush assembly structure adopts the overall vulcanization structure of the rubber main spring, the outer sleeve, and the inner sleeve, which can only be increased or simultaneously adjusted by adjusting the rubber main spring material. Reduce the isotropic stiffness of the mount, and since the main spring structure of the traditional bush-type rubber mount has been fixed, the ratio of the isotropic stiffness of the mount cannot be adjusted, so the traditional bush-type rubber mount cannot make the stiffness of the isotropic Adjust the decoupling, so that it is impossible to change the stiffness of the suspension in all directions and the ratio of stiffness in all directions at the same time, resulting in the suspension not being able to be optimally designed according to the needs, and the rubber main spring structure needs to be redesigned to solve the problem
