Air supply output device of air suspension

Abstract

The invention discloses an air supply output device of an air suspension. The air supply output device comprises a motor, the compression pump body is arranged at one end of the motor; a main shaft of the motor is inserted into the compression pump body; the compression pump body is internally provided with an inner operation cavity, a first cavity and a second cavity, the first cavity and the second cavity are arranged on the two sides of the inner operation cavity respectively, the two ends of the inner operation cavity are provided with a first compression cavity and a second compression cavity respectively, a first piston is movably arranged in the first compression cavity, and a second piston is arranged in the second compression cavity. The first piston and the second piston are driven by a main shaft of the motor to axially move in the same direction; the first compression cavity and the second compression cavity are communicated with the first cavity through a first one-way valve and a second one-way valve respectively, the second cavity is communicated with the second compression cavity, an exhaust port communicated with the second cavity is formed in the compression pump body, and an exhaust heat dissipation pipe is connected to the exhaust port. A two-stage compression air pump structure is adopted, and the problems that an existing air supply unit is large in size, heavy in mass, large in noise and poor in heat dissipation effect are solved.

Description

technical field [0001] The invention relates to the field of automobile air suspension, in particular to an air suspension air supply and output device. Background technique [0002] As an important part of the car's active suspension system, the air suspension is mainly composed of an air supply unit, an air spring, a shock absorption damping device, a lateral stabilizer, a height valve, a guiding force transmission mechanism, an air storage tank, and a pipeline. Real-time adjustment of the stiffness and damping of the suspension based on the motion state of the car and the road surface conditions, so that the suspension system is in the best shock absorption state, so that the vehicle has good comfort under various road conditions. With the development of people's requirements for vehicle ride comfort and suspension technology, air suspension is widely used in large passenger cars, heavy trucks, special vehicles and high-end small cars. [0003] As the core component of t...
