The invention provides air filtering equipment for an air suspension. The air filtering equipment comprises a filter shell, a filter element and an air return pipe; a filter cavity is formed in filtershell; the filter shell is provided with an exhaust port, and an air inlet and a pressure relief port which are communicated with the filter cavity; a first mounting pipe and a second mounting pipe are arranged at one end of the filter shell, a first mounting cavity is formed in the first mounting pipe, a pressure release valve is mounted in the first mounting cavity, a second mounting cavity communicated with the exhaust port and the first mounting cavity is formed in the second mounting pipe, and an electromagnetic valve is mounted in the second mounting cavity; a gap is reserved between the filter element and the inner wall of the filter shell; the end, close to the air inlet, of the filter element is open, and an air outlet communicated with the exhaust port is formed in the end, awayfrom the air inlet, of the filter element; the air return pipe is connected with the first mounting pipe and communicates with the first mounting cavity. The automobile air suspension system integrates the functions of filtering and drying, air path control, overpressure protection and the like, the number of parts of the automobile air suspension system is reduced, and application is more convenient.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to an air filter device for an air suspension. Background technique [0002] As an important part of the active suspension system of a car, the air suspension can adjust the stiffness, damping and height of the suspension in real time according to the movement 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 can Good comfort in all road conditions. At present, air suspension is widely used in large passenger cars, heavy trucks, special vehicles and high-end small cars. [0003] The air suspension adjusts the stiffness, damping and height of the suspension mainly by high-pressure air, and the high-pressure air of the air suspension is provided by an air pump, which can suck in external air and compress it to a certain pressure before entering the air spring. In order to avoid adverse effect...
