Abstract

A bolt limiting type suspension cushion assembly comprises an upper framework, vulcanized rubber and a lower framework, wherein the upper framework and the lower framework are vulcanized integrally through the vulcanized rubber; and downward turning edges are arranged on two sides of the upper framework, upward turning edges are arranged on two sides of the lower framework, the two upward turning edges are arranged on outer sides of the two downward turning edges, and the downward turning edges are matched with the adjacent upward turning edges in a limited manner through limiting bolts fixedly connected with the outer sides of the downward turning edges. The assembly is convenient to install, good in damping effect and capable of effectively preventing tearing of the vulcanized rubber and prolonging the service life.

Description

technical field [0001] The invention relates to an engine suspension device, in particular to a bolt-limited suspension cushion assembly, which is particularly suitable for prolonging service life and preventing tearing of vulcanized rubber. Background technique [0002] As an important supporting component and vibration isolation component of the powertrain, the engine mount plays a vital role. Excessive vibration during vehicle driving will affect the performance of the power system, thereby affecting the safety of the vehicle. The engine mount is responsible for The task of protecting the engine and surrounding accessories has the functions of vibration absorption, vibration reduction, vibration isolation, and noise reduction. Therefore, optimizing the engine mount can improve the stability of the vehicle power system and the ride comfort of the vehicle. As the main cushioning part of the engine suspension cushion, the rubber pad has the characteristics of strong compress...
