A passenger car air suspension airbag pressure regulating device and its control method

Abstract

The invention discloses a passenger car air suspension air bag pressure regulating device, which comprises an air suspension, a conveying pipeline arranged on the top of the air suspension, a joint fixed and sealed with the conveying air suspension arranged at the bottom of the conveying pipeline, arranged on the connecting The air guide tube above the head is arranged on the arc tube connected with the air delivery tube above the air guide tube, the air compressor is arranged above the air delivery tube, and the rotating plate used to control the air flow is arranged inside the arc tube. The air suspension includes an airbag and an upper shock absorber arranged above the airbag. The beneficial effect of the present invention is: adopting this method of use, when the vehicle is reversing, an electric signal is sent from the vehicle center console to the two-position three-way solenoid valve. The load weight of the three axles reduces the reversing resistance and tire wear, effectively improves the service life of the three axles, and increases the safety performance of the vehicle.

Description

technical field [0001] The invention relates to a passenger car air suspension air bag pressure regulating device and a control method thereof, belonging to the technical field of passenger cars. Background technique [0002] At present, the air suspension airbags used in vehicles rely on many electrical components to control the air in and out of the airbags. Due to the high cost of using electrical components, and long-term use, the internal circuits are likely to be burned or damaged, resulting in failure to properly control the air. The suspension airbag is controlled, which will make the shock absorption effect of the vehicle poor when it is in use, and give the passengers in the car a poor ride experience. When the existing three-axle bus reverses, the third axle is locked, and when the reverse turns, the third axle drags heavily on the ground, the tires wear relatively quickly, and the reverse resistance is large, which affects the use of the vehicle.
