An air compressor for new energy vehicles

Abstract

The invention discloses an air compressor for a new energy vehicle. The air compressor for the new energy vehicle comprises a base, a filter installation seat, a drive motor, a screw air compressor main machine, an oil-gas separation tank, an oil liquid filter, an oil-gas filter and an oil liquid cooler. The oil-gas separation tank comprises a tank body and a separation drum arranged in the tank body. The separation drum comprises a drum body, wherein the upper end of the drum body is provided with a V-shaped opening. The oil-gas filter and the oil liquid filter are fixedly installed on the filter installation seat. The upper end of the tank body is provided with a connecting seat. The screw air compressor main machine and the drive motor are fixedly installed on the connecting seat. According to the air compressor for the new energy vehicle, oil and gas are effectively separated through the oil-gas separation tank, and the oil content of the compressed air conveyed out from the oil-gas separation tank to the oil-gas filter is reduced; and therefore, the service life of the oil-gas filter is prolonged, the use cost is reduced, space is fully utilized, the occupied area of an air compressor system is reduced, and the structure of the air compressor is more compact.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to an air compressor used for new energy vehicles. Background technique [0002] The compressed air required for vehicle braking, door opening and closing, suspension pedal lifting and other pneumatic devices in the car is provided by the on-board air compressor system. The traditional on-board air compressor is a reciprocating piston air compressor with a complex structure. It takes up a lot of space and is not suitable for new energy vehicles. For example, a screw air compressor for electric passenger cars disclosed in patent 200820169730.4 includes a screw air compressor main unit, a motor connected to the air compressor main unit, an air storage tank, an oil storage tank and an oil cooler, wherein the air storage tank and the oil storage tank It is integrated with the main engine of the air compressor to solve the problem that the existing vehicle air compressor takes u...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies and defects of the existing technology, an air compressor for new energy vehicles is provided, which solves the problem that the air compressor system occupies a large space, and the oil and gas output by the screw air compressor host through the oil and gas separation tank Carry out effective separation and reduce the oil content of the compressed air output from the oil-air separation tank to the oil-air filter, so as to prolong the service life of the oil-air filter and reduce the cost of use
