Embodiment Construction

[0038] see Figure 1 to Figure 4 According to an embodiment of the present invention, the automobile air suspension system facing extreme driving conditions includes an air spring and an air compression device communicating with it and capable of quickly inflating the gas pressure of the inner upper chamber and the inner lower chamber.

[0039] Wherein, the air spring includes a rubber airbag 3, a hollow base 8 communicating with the rubber airbag 3, the rubber airbag 3 being the inner upper chamber of the air spring, and the base being the inner lower chamber. The upper and lower ends of the rubber airbag 3 are sealed by the upper end cover 2 and the lower pressure plate 6 respectively. The upper end cover 2 is provided with an inflation and discharge pipe 1, and a cushion pad 5 is installed on the upper part of the lower pressure plate, and a through hole 4 is left in the middle to communicate with the rubber airbag 3. Cavity and base 8 cavities, base 8 lower end is provided...

Abstract

The invention discloses an air suspension system and a control method for a vehicle under a rushing working condition. The vehicle air suspension system comprises an air spring and an air compressiondevice. The two ends of an air bag are sealed through an upper cover plate and a lower pressing plate, and the air bag is communicated with an additional air chamber through an air inlet pipeline andan air outlet pipeline; a buffer pad is mounted on the lower pressing plate; the whole base is in a hollow ring shape, an inner ring wall which extends downwards but does not make contact with the bottom is arranged at the top in the base, and an inflation pipe is arranged at the bottom of the base. And an air compression device is arranged on the inner ring wall. The vehicle can trigger the air compression device to work under the urgent running working condition, and the working rule of the air compression device is determined by the control method.

Description

technical field [0001] The invention relates to automobile suspension technology, in particular to a vehicle air suspension system and a control method aimed at rapid driving conditions. Background technique [0002] With the improvement of people's living standards and the rapid development of automotive electronic technology, people expect to continuously improve the requirements for ride comfort, handling stability and ride comfort of vehicles. Vehicle suspension is the core component that affects ride comfort, handling stability and ride comfort. Among them, the traditional passive suspension, which cannot be changed once the suspension parameters are set, cannot meet complex and changeable working conditions; while the air suspension has the functions of nonlinear stiffness and active adjustment of vehicle height. Both domestic and foreign research results and market reflections show that air suspension can not only significantly improve the overall performance of vehi...
