Vehicle suspension system and automobile having same

Abstract

The invention discloses a vehicle suspension system and an automobile having the same. The vehicle suspension system comprises an integral rear axle, a body longitudinal beam, a limit block and a buffer block. The body longitudinal beam and the integral rear axle are spaced in the vertical direction and the distance between the body longitudinal beam and the integral rear axle in the vertical direction can be adjusted; the limit block is arranged on the integral rear axle and the upper end face of the limit block is spaced with the body longitudinal beam; the buffer block is arranged on the body longitudinal beam and arranged in a staggered manner relative to the limit block in the horizontal direction; the buffer block is spaced with the integral rear axle; the vertical distance between the lower end face of the limit block and the upper surface of the integral rear axle is less than the vertical distance between the upper end face of the limit block and the lower surface of the body longitudinal beam. According to the embodiment of the invention, the compression stroke is increased, the buffer time is prolonged, the impact is small, and therefore the comfort of the vehicle is improved. The overall sulfurized size of the limit block can be decreased, the number of manufactured cavity dies is increased, the manufacturing process is simplified and the production efficiency is improved.

Description

technical field [0001] The present invention relates to the field of vehicle technology, more specifically, to a vehicle suspension system and an automobile with the same. Background technique [0002] The automobile suspension system is an elastically connected part between the frame (or body) and the wheel, and is an important part of a modern automobile. The main function of the suspension system is to transmit all the forces and moments acting between the wheels and the frame (or body), and to ease the impact load transmitted from the road to the frame (or body), while ensuring that the suspension has a certain beating stroke. Protect the vehicle with sufficient ground clearance. [0003] In the related art, the buffer block of the leaf spring type rear suspension system is arranged on the integral rear axle, and the buffer block, the integral rear axle and the leaf spring below the integral rear axle are fixedly connected together by saddle bolts and leaf spring pressu...

AI Technical Summary

Problems solved by technology

Because the structure of the buffer block is an independent rubber buffer block structure, the buffer block of this structure has small volume compression, high rigidity, short buffer time, large impact, and insufficient suspension travel.

Moreover, once the buffer block touches the longitudinal beam of the vehicle body, it will quickly affect the bias frequency of the rear suspension system, thereby changing the bias frequency matching of the front and rear suspensions of the vehicle, and affecting the comfort of the vehicle
