Oil-free air compressor for new energy vehicle

Abstract

The invention discloses an oil-free air compressor for a new energy vehicle, and relates to the field of compressors. The device comprises a motor and a base, wherein the motor is fixedly connected tothe base; a spindle is connected to the motor; the spindle is rotatably connected to an end cover and a cylinder body, a swash plate sleeves the spindle and rotates along with the spindle; a planetary plate is rotatably connected to the swash plate and hinged with a plurality of piston components; the planetary plate only performs up-down reciprocating swinging motion through anti-rotation components; pistons perform reciprocating linear motion in the cylinder body; the end cover, the cylinder body and a cylinder cover are sequentially connected together; exhaust components are connected between the cylinder cover and the cylinder body; and a lubricating system provides lubricating oil for the rotating connection positions of all components in the compressor. The compressor has the characteristics of being low in vibration noise, high in reliability, low in cost, clean in compressed air and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an oil-free air compressor for new energy vehicles. Background technique [0002] New energy vehicles have been strongly supported and promoted by the government in our country, and have the advantages of zero pollution, low noise, energy saving and high efficiency. Over the past ten years of domestic development of new energy vehicles, the requirements for vehicle vibration, noise and energy saving have become higher and higher. At present, most of the air compressors for new energy vehicles on the market are oil-injected vane Piston machine, oil-free scroll machine and ordinary oil-free piston machine. The oil-injected sliding vane compressor has low vibration and noise, but there are problems of emulsification and oil leakage; the piston machine with oil is more reliable, but the vibration noise is large, the energy consumption is high, and there is oil leakage; the air o...
