Hydraulic suspension of automobile cab

Abstract

The invention relates to a hydraulic suspension of an automobile cab, belonging to the field of automobile part and aiming to replace the traditional rubber suspension. The hydraulic suspension of theautomobile cab mainly comprises an upper liquid chamber, a lower liquid chamber, a shell, a buffering limited block, an inertia passage body, a bottom membrane, a main rubber spring, metallic frameworks and a base, wherein the shell is in an annular structure and embedded into the base; the main rubber spring is connected with the metallic frameworks in a vulcanizing way, wherein the metallic frameworks are positioned on the inner edge and the outer edge of the main rubber spring; the inertia passage body is in an annular structure and is provided with an annular inertia passage and a decoupling passage playing a damping role; the lower liquid chamber consists of the metallic frameworks, the main rubber spring and the buffering limited block; the upper liquid chamber consists of the inertia passage body and the bottom membrane; and liquid inside the upper liquid chamber and the lower liquid chamber flows through the inertia passage. The hydraulic suspension has the advantages of compacter structure, reliable work, low cost and wide application and can effectively improve the NVH characteristic and other characteristics of the automobile cab.

Description

Technical field: [0001] The invention relates to a hydraulic mount for an automobile cab, which belongs to the field of automobile parts. Background technique: [0002] In recent years, on the one hand, with the development of automobile design towards high torque and light weight, the vibration of the engine has increased and the NVH (noise, vibration and harshness) characteristics of the vehicle have deteriorated. The comfort requirements of automobiles are getting higher and higher, and the traditional cab mounts cannot well meet the vibration isolation requirements between the cab and the frame. Objectively, it is required to design cab mounts with excellent performance. Invention content: [0003] The purpose of the present invention is to provide a brand-new automobile cab hydraulic mount to replace the traditional automobile cab mount, and fundamentally solve the NVH problem of the automobile cab. Vibration energy is consumed through the liquid damping effect of th...
