Problems solved by technology

[0003] At present, there are air spring and leaf spring composite suspensions, but the air spring is arranged in the middle of the axle. This arrangement reduces the roll performance of the suspension, and at the same time limits the installation height and working efficiency of the air spring. journey

Abstract

The invention relates to a composite non-independent suspension system of an air spring and a leaf spring. The suspension system consists of a leaf spring, a leaf spring front-end lifting lug, a leaf spring rear-end rolling ear, U-shaped bolts, a leaf spring pressure plate, a buffer block, Shock absorber, transverse stabilizer bar, stabilizer bar and frame mounting bracket, stabilizer bar tie rod, frame, axle, air spring, air spring upper mounting bracket, air spring lower mounting bracket and air spring height adjustment mechanism are assembled; The invention utilizes the respective advantages of the air spring and the leaf spring, can make up for their respective deficiencies, and improves the ride comfort and roll stiffness of the suspension system.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension, in particular to a composite non-independent suspension system of an air spring and a leaf spring. Background technique [0002] The traditional leaf spring non-independent suspension has the advantages of simple structure and reliable operation, and is widely used in various vehicle models. However, the leaf spring also has disadvantages such as large friction, poor load adaptability, and poor ride comfort. The application of air springs makes up for the shortcomings of leaf springs to a certain extent. When the air spring suspension is used, the working height of the body under different loads can be kept constant, and the natural frequency of the suspension under different loads can also basically remain unchanged, which has a good ability to absorb high-frequency vibrations. If the air spring and the leaf spring are combined Forming a composite suspension system will greatly im...
