Vibration-absorbing and noise-absorbing light engine suspension

Abstract

The invention discloses a vibration-absorbing and noise-absorbing light engine suspension. The suspension comprises a housing and an inner core located in the housing, the inner core at least comprises an upper plate body and a lower plate body which are oppositely arranged, the upper and lower plate bodies are connected with an inner top face and an inner bottom face of the housing respectively,the upper plate body comprises a first layer plate, a first interlayer and a second layer plate which are sequentially connected from top to bottom, the first interlayer plate is beehive-shaped, the longitudinal cross section of the first interlayer plate is formed by the sequential connection of multiple rows of regular hexagons, a circle which is connected with three diagonal lines of the regular hexagon is arranged in each regular hexagon, and the diameters of the circles in the hexagons in each layer are gradually increased from top to bottom. The suspension has the advantages that when anengine is in an idle state and the vibration amplitude is larger, vibration generated by the engine is absorbed by the upper plate body by generating larger damping effect, and a gradient vibration absorbing function is achieved; the problem that traditional rubber can only provide a smaller damping effect is solved, and a better vibration reduction effect is achieved.

Description

technical field [0001] The invention relates to a lightweight engine mount for reducing vibration and absorbing noise. Background technique [0002] A car is a vibrating body with multiple degrees of freedom, and vibrates under the action of various vibration sources. The engine is one of the sources of vibration. It is installed on the frame through the suspension device. The suspension device is both an elastic element and a vibration damping device. Its characteristics are related to the vibration and noise of the whole vehicle, and thus directly related to the riding experience of passengers. Reasonable suspension can not only reduce vibration, reduce noise and improve ride comfort, but also improve the life of parts, components and the whole vehicle. Traditional automobiles are generally equipped with rubber mounts. Although they have the characteristics of simple structure and low manufacturing cost, the characteristic curves of dynamic stiffness and damping loss angl...

AI Technical Summary

Problems solved by technology

Traditional automobiles are generally equipped with rubber mounts. Although they have the characteristics of simple structure and low manufacturing cost, the characteristic curves of dynamic stiffness and damping loss angle basically do not change with the excitation frequency, that is, the upper limit of the vibration reduction effect of rubber mounts is relatively low. Low, it is difficult to meet the requirements of modern passengers for ride comfort, and the vibration damping effect of the rubber suspension will drop sharply after long-term use, and at the same time, it will generate noise, which will affect the ride experience
