Special high speed piston type electric vacuum pump body structure

Abstract

The invention relates to the technical field of brake booster systems for new energy vehicles, in particular to a special high-speed piston-type electric vacuum pump body structure. The technical solution adopted in the present invention is: a special high-speed piston electric vacuum pump pump body structure, including the pump casing structure, the right side of the pump casing structure is the first assembly end, and the upper end of the pump casing structure is the second assembly end. The front of the pump housing structure is connected with a cover plate structure, the first assembly end is connected with the cylindrical first piston chamber, the second assembly end is connected with the cylindrical second piston chamber, and the center of the pump housing structure is provided with a cylindrical Shaped piston turning shaft, the front of the piston turning shaft is provided with a motor connecting shaft, and the center position of the back side of the piston turning shaft is connected with the first piston connecting frame. The invention has the advantages of simple structure, convenient use, more stable performance during use, better vacuuming efficiency, safer and more reliable high-speed piston electric vacuum pump, and lower use cost.

Description

technical field [0001] The invention relates to the technical field of brake booster systems for new energy vehicles, in particular to a special high-speed piston-type electric vacuum pump body structure. Background technique [0002] The vacuum pumps used in the brake booster systems of pure electric, hybrid and other types of new energy vehicles are mostly low-speed piston vacuum pumps or high-speed vane vacuum pumps on the market. There is the hidden danger that the blade is fragile again in the type vacuum pump. In view of the combination of the two, we have developed a high-speed piston vacuum pump, which has both the efficiency advantages of a high-speed pump and the lifespan advantage of a piston pump, and reduces the volume and quality of the product in light of the automotive industry's pursuit of lightweight. Contents of the invention [0003] The purpose of the present invention is to provide a special high-speed piston-type electric vacuum pump pump body struc...
