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 an air spring and plate spring composite non-independent suspension system. The suspension system is formed by assembling of a plate spring, a plate spring front end lifting lug, a plate spring rear end spring lug, a U-shaped bolt, a plate spring pressing plate, a buffer block, a vibration absorber, a horizontal stabilized bar, a stabilized bar mounting bracket, a vehicle frame mounting bracket, a stabilized bar pull rod, a vehicle frame, a wheel axle, an air spring, an air spring upper mounting bracket, an air spring lower mounting bracket and an air spring height regulating mechanism. According to the air spring and plate spring composite suspension system disclosed by the invention, the respective advantages of the air spring and the plate spring are utilized, so that the respective defects can be overcome, and the smoothness and the roll stiffness of the suspension system are improved.

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...
