Novel automobile engine rear suspension cushion assembly

Abstract

The present invention is a new automobile engine rear suspension cushion assembly, including an inner frame and an outer frame. There is a vulcanized rubber body between the inner and outer frames. At the same time, the outer frame is wrapped in the vulcanized rubber body. The outer diameter of the inner frame passes through a taper transition section to a straight line section; the corresponding outer skeleton also includes a straight section, the straight section is provided with an inclination angle, the inclination angle is downwardly provided with a vertical section, and a hook is provided behind the vertical section; the inclination angle of the outer skeleton corresponds to the outer diameter of the inner skeleton The taper transition section, the vertical section of the outer skeleton corresponds to the straight section of the outer diameter of the inner skeleton; the shock-absorbing arc of the shoulder of the rubber body is an outer arc. The present invention vulcanizes the inner and outer skeletons and the vulcanized rubber body as one, and adjusts the original inner skeleton structure at the same time. The upper part is changed from an arc excessive design to an inclination angle design, that is, a taper transition section design, which is consistent with the inclination angle of the outer skeleton. It can reduce the shear strength of rubber and improve the fatigue life of products.

Description

technical field [0001] The invention relates to the technical field of automobile engine mounts, in particular to a novel automobile engine rear mount cushion assembly, which is used for isolating vibration between the engine and the vehicle frame. Background technique [0002] At present, the fatigue life of the engine mount is short, the isolation and shock absorption effect of the engine and the frame is poor, and the passenger comfort is poor, which eventually leads to fatigue damage of the engine and other components due to excessive vibration. [0003] Such as figure 1 shown. Including inner skeleton-A, outer connecting skeleton-B, vulcanized rubber-C, shoulder shock-absorbing radian-D, vulcanized rubber-C between inner skeleton-A and outer connecting skeleton-B, wherein the outer diameter of inner skeleton-A is The middle part is reduced to the tail end through a circular arc transition, and the outer connecting frame-B is a plane body, with an inclination angle and...

AI Technical Summary

Problems solved by technology

In this product, the outer diameter arc transition of the inner skeleton-A is too tight, and the rubber shear angle is formed with the inclination angle of the outer connecting skeleton-B, the life of the vulcanized rubber-C will be greatly reduced, and the shock-absorbing arc of the shoulder-D Concave arcs also age prematurely with rubber shear angles
