Description

Technical Field

[0001] The utility model relates to the technical field of air supply equipment, in particular to air supply equipment for automobile air suspension. Background Art

[0002] As an important part of the active suspension system of automobiles, air suspension is mainly composed of air springs, guide transmission mechanisms, shock absorbing and damping devices, lateral stabilizers, height valves, air supply units, energy storage devices, and pipelines. The existing patent is an air supply device for automobile air suspension, and the patent announcement number is CN212860990U, which includes a compression unit and a drying and filtering unit; the piston is movably installed in the air cavity and the air cavity is divided into a primary compression chamber, an air intake chamber, and a secondary compression chamber. The air intake chamber is connected to the air intake pipe, and the secondary compression chamber is connected to the air outlet. The piston is provided with an air passage and a first air vent connecting the air intake chamber and the primary compression chamber. The piston is also provided with a second air vent connecting the primary compression chamber and the air passage and a third air vent connecting the secondary compression chamber and the air passage; the connecting rod group is connected to the piston and the connecting rod group is driven by a motor to drive the piston to reciprocate up and down; the filter housing is connected to the compression housing and the air outlet of the compression housing is connected to the filter chamber, and the filter element is installed in the filter chamber. The utility model adopts two-stage compression technology, and the maximum output gas can reach 21Bar. The high output gas pressure can effectively improve the adjustment sensitivity of the automobile air suspension system; the functions are integrated and the total volume is smaller.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the air supply equipment for automobile air suspension actually supplies air to the automobile suspension, the air is only filtered through the filter element in the dry filter unit, and the filter element can only intercept a limited amount of impurities in the air and is unable to intercept some extremely fine dust particles, thereby causing fine dust particles to enter the interior of the air suspension and affecting the service life of the air suspension. In addition, the air supply equipment for automobile air suspension also has the defect that it is relatively cumbersome to clean the intercepted impurities.

[0004] Therefore, we propose an air supply device for automobile air suspension to solve the above problems. Utility Model Content
