Abstract

The invention relates to the technical field of air compressors, in particular to a wear-resistant air compressor piston for a new energy automobile. The wear-resistant air compressor piston comprises a base, kidney-shaped round holes and shaft pins, the base is composed of a disc and two connecting piles, the two connecting piles are welded on two sides of the bottom end of the disc, the kidney-shaped round holes are formed in the connecting piles, and the shaft pins are arranged in the kidney-shaped round holes. A limiting seat is fixed to the bottom of the base, the center of the limiting seat protrudes and is provided with a through hole in a penetrating mode, the top end of the limiting seat penetrates through the disc and is flush with the upper surface of the disc, the periphery of the limiting seat is fixedly connected with the disc through bolts, and a connecting assembly is arranged on the upper surface of the base. And the connecting assembly comprises a fixing seat and a connecting table, the bottom of the fixing seat is in a step shape, the bottom end of the fixing seat penetrates through the limiting seat, and the bottom end of the fixing seat is integrally connected with an ejector rod. The wear-resistant air compressor piston has the variable diameter design along with the process, the abrasion strength in the piston movement is reduced, and the service life of the piston is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to wear-resistant air compressor pistons used in new energy vehicles. Background technique [0002] New energy vehicles need to use many high-pressure gas as power components, such as cylinders and other components. High-pressure gas needs to be generated by air compressors. Piston air compressors are small in size and long in life, and are widely used in automobiles. [0003] The Chinese invention patent with the publication number CN112879267A discloses a wear-resistant air compressor piston used in a new energy vehicle, including a piston skirt, and a wear-resistant coating is provided on the outer circumferential surface of the piston skirt; the wear-resistant coating includes the following The components are: 9-12 parts by weight of polytetrafluoroethylene, 1-1.5 parts by weight of molybdenum disulfide, 1.5-2.5 parts by weight of aramid fiber and 0.1-0.2 parts by weight...
