A flexible shock-absorbing automobile chassis structure

Abstract

The invention discloses a flexible damping automobile chassis structure which comprises a rear axle, a transverse swing arm and a hanging device. The center of the rear axle is connected with a longitudinal thrust pipe in the forward direction, the upper portion of the longitudinal thrust pipe is provided with a transverse swing arm, the transverse swing arm comprises a left pull rod, a right pullrod and a central rocker arm, the lower end of the central rocker arm is connected with the longitudinal thrust pipe through a pin shaft, and the upper end of the central rocker arm is connected to aframe; the two ends of the rear axle are respectively provided with a hub, a shock absorber and a helical spring; an upper end ring of each helical spring is connected with the frame through a connecting piece; a stabilizing rod is arranged between the connecting pieces, a hanging device is arranged on the stabilizing rod, and a mounting seat is arranged on the hanging device to enable the hanging device to be connected with the frame. The transverse swing arm device and the hanging device can effectively reduce vertical swing and transverse swing of an automobile chassis in driving, increaseflexibility and riding comfort of the automobile chassis, and improve stability and safety in the driving process of the automobile.

Description

technical field [0001] The invention belongs to the technical field of automobile chassis structures, and in particular relates to a flexible shock-absorbing automobile chassis structure. Background technique [0002] With the rapid development of cars, family cars are no longer luxury accessories, but as a means of transportation, people are paying more and more attention to the safety and comfort of family cars. Safety is the foundation, comfort is the pursuit, and comfort is the key to a The importance of a sedan is self-evident, and the comfort is mainly reflected in the adjustment of the chassis and suspension of the car. As the name suggests, the suspension is the support of the chassis, and the strength of the tire feedback from the road is conveyed to the driver through the suspension. Human beings are currently divided into independent suspension and non-independent suspension. The comfort of independent suspension is better than that of non-independent suspension. ...
