Integrated air supply unit of air suspension

Abstract

The integrated air supply unit of the air suspension comprises a damping support and a motor, and the motor and a compression pump body are installed on the damping support; the distribution valve assembly is mounted on one side of the motor; an operation inner cavity, a first cavity and a second cavity are formed in the compression pump body, a first compression cavity and a second compression cavity are formed in the two ends of the operation inner cavity respectively, a first piston and a second piston are arranged in the operation inner cavity, and the first piston and the second piston are driven by a main shaft of a motor to axially move in the same direction; the first compression cavity and the second compression cavity are both communicated with the first cavity, the second cavity is communicated with the second compression cavity, the second cavity is provided with an exhaust port, the exhaust port is connected with an exhaust heat dissipation pipe, the exhaust heat dissipation pipe is connected with the distribution valve assembly through a first connecting pipe, and the secondary air inlet is connected with the distribution valve assembly through a second connecting pipe. 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 integrated air supply unit of the air suspension. Background technique [0002] As an important part of automotive active suspension system, air suspension is mainly composed of air supply unit, air spring, shock absorption and damping device, lateral stabilizer, height valve, guiding force transmission mechanism, air storage tank (AT), and pipeline. , can adjust the stiffness and damping of the suspension in real time according to the motion state of the car and road 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 the air suspens...
