Problems solved by technology

[0003] At present, the existing air spring and leaf spring composite suspensions all arrange the air spring between the leaf spring and the lifting lug. This arrangement not only reduces the roll performance of the suspension, but also limits the installation height of the air spring. and work itinerary

Abstract

The invention discloses a compound automobile suspension system, which is installed between an automobile frame and an axle, and comprises two leaf springs symmetrically located below a vehicle body.The two ends of the leaf springs are hinged to the frame. The extension direction of the leaf springs is consistent with the extension direction of the frame. The middles of the leaf springs are fixedly connected with the axle. An air spring and a shock absorber are installed between the middles of the leaf springs and the frame. The air spring is connected with an air spring height adjustment mechanism. The air spring and the leaf springs together work as elastic elements to bear loads, the leaf springs also play a guiding role, the shock absorber and the air spring are connected with the leaf springs, so that the structure is simple and compact, and implementation is easy. By controlling the air inlet and air outlet of the air spring, the working height of the vehicle body can be kept constant under different loads, the natural frequency of the suspension system can also be kept basically unchanged under different loads, and the smoothness of the suspension system is improved throughthe excellent ability of absorbing high-frequency vibration.

Description

technical field [0001] The invention relates to the technical field of automobile suspension, in particular to an air spring and leaf spring composite suspension system for light trucks. Background technique [0002] Traditional leaf springs have the advantages of simple structure and reliable operation, and are widely used in various vehicle models. However, leaf springs also have 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 into a composite suspension system, the performance of the suspension will be greatly imp...
