Problems solved by technology

[0004] However, the existing integral bridge suspension has the following defects: (1) the leaf spring 2' has a large weight, which is not conducive to the lightweight design of the vehicle; (2) when the leaf spring 2' moves, the plates rub against each other , resulting in dynamic stiffness and poor ride comfort; (3) The unsprung mass of the suspension is high, which is not conducive to handling stability

Abstract

The invention discloses an integral bridge type suspension. According to the invention, single-piece leaf springs of the integral bridge type suspension are symmetrically installed on the two sides of an axle in a width direction; two shock absorbers are located on the front side and the rear side of the axle respectively, and the two ends of each shock absorber are connected with the axle and a vehicle body respectively; and an axial through hole is formed in each elastic supporting unit, an annular protrusion is arranged on the outer wall face of the elastic supporting unit, the elastic supporting unit corresponds to the middle area of one single-piece leaf spring, one end face, in the axial direction, of the elastic supporting unit is connected with the single-piece leaf spring or a vehicle body, and the other end face of the elastic supporting unit in the axial direction corresponds to the single-piece leaf spring or the vehicle body. According to the integral bridge type suspension, through the design of the single leaf springs and the elastic supporting units, the weight of the suspension is reduced, and economical efficiency and control performance are improved. Moreover, the integral bridge type suspension can provide different rigidities according to different loads, so the bearing capacity of the suspension is ensured, and riding comfort is improved.

Description

technical field [0001] The invention relates to the field of vehicle engineering, and more specifically, relates to an integral bridge suspension. Background technique [0002] Suspension is an important part of modern automobiles. Its function is to elastically connect the frame or body with the axle or wheels, transmit force and moment between the vehicle and the frame or body, and ease the transmission of the road surface to the frame or body. The impact load, damping vibration, and isolating the noise from the ground and tire input, controlling the movement law of the wheel, to ensure that the car has the required ride comfort and handling stability. [0003] like figure 1 As shown, the existing integral bridge suspension uses the leaf spring 2' as the elastic element, and the leaf spring 2' is connected with the axle 1' through the saddle bolt 3', and the leaf spring 2' plays the role of bearing and guiding . The overall bridge suspension damps the vibration through ...
