Pressure regulating device and control method for air suspension airbag of passenger car

Abstract

The invention discloses a pressure regulating device for an air suspension airbag of a passenger car. The pressure regulating device comprises air suspension, conveying pipelines, connectors, air-guiding pipes, arc-shaped pipes, air compressors and rotating plates, wherein the conveying pipelines are arranged at the top of the air suspension, the connectors are arranged at the bottoms of the conveying pipelines and fixedly sealed with the air conveying suspension, the air-guiding pipes are arranged on the connectors, the arc-shaped pipes are arranged on the air-guiding pipes and connected withair-conveying pipes, the air compressors are arranged on the air-conveying pipes, and the rotating plates are arranged in the arc-shaped pipes and used for controlling the air flow; and the air suspension comprises the airbag and an upper damper arranged on the airbag. The pressure regulating device has the beneficial effects that by adopting a using method, when a vehicle is backed up, an electric signal is sent out from a center console of the vehicle to a two-position three-way solenoid valve, at the moment, the device starts to work, the pressure of a three-axle suspension airbag can be reduced, the load weight of three axles is decreased, thus back-up resistance and tire abrasion are reduced, the service life of the three axles is prolonged effectively, and the safety performance ofthe vehicle is improved.

Description

technical field [0001] The invention relates to a passenger car air suspension airbag 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.
