Embodiment 1

[0020] see Figure 1-8 , an embodiment 1 provided by the present invention: including a base 1, a waist hole 2 and a shaft pin 3, the base 1 is composed of a disk and two connecting piles, and the two connecting piles are welded on both sides of the bottom end of the disk , a waist hole 2 is opened on the connecting pile, and a shaft pin 3 is arranged in the waist hole 2, such as figure 1 As shown, the pivot pin 3 is used to connect external parts.

[0021] The bottom of the base 1 is fixed with a limit seat 6, and the center of the limit seat 6 protrudes and is provided with a through hole. The top of the limit seat 6 runs through the disc and is flush with the upper surface of the disc. It is connected and fixed by bolts to the disc. The upper surface of the base 1 is provided with an engaging assembly 4. The engaging assembly 4 includes a fixing seat 41 and an engaging platform 42. The bottom of the fixing seat 41 is stepped, and the bottom end of the fixing seat 41 runs t...

Abstract

The invention relates to the technical field of air compressors, in particular to wear-resistant air compressor pistons used in new energy vehicles, including a base, a waist hole and a shaft pin. The base is composed of a disc and two connecting piles, and the two connecting The piles are welded on both sides of the bottom end of the disc, and a waist hole is opened on the connection pile, and a shaft pin is arranged in the waist hole, the bottom of the base is fixed with a limit seat, and the center of the limit seat is raised And a through hole is opened through, the top of the limit seat runs through the disc and is flush with the upper surface of the disc, the periphery of the limit seat is connected and fixed with the disc by bolts, and the upper surface of the base is provided with a joint Assemblies, the connecting assembly includes a fixed seat and a connecting platform, the bottom of the fixed seat is stepped, the bottom end of the fixed seat passes through the limit seat, and the bottom end of the fixed seat is integrally connected with a push rod. The invention has a variable diameter design along with the process, reduces the wear intensity during the piston movement, and greatly improves the service life of the piston.

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...
