Automotive electrically driven air compressor, pneumatic system and vehicle

Abstract

The invention relates to an air compressor for automobiles, and discloses an automotive electrically driven air compressor, an automotive pneumatic system comprising the electrically driven air compressor and a vehicle comprising the pneumatic system. The automotive electrically driven air compressor comprises a cylinder cover, a cylinder body, a mounting support, a motor, an oil pan, a base and an oil cooler, a connecting rod assembly, a piston, a crankshaft, a rear cover and other structures are arranged in the cylinder body, one end of the oil cooler is provided with an oil inlet tube for lubrication and cooling, and the other end of the oil cooler is provided with a return cooling oil tube. An oil chamber is arranged in the cylinder cover, a lubrication pump is arranged on the left end of the cylinder body, and thereby the lubrication and cooling system and the air compressor are integrated together. The air compressor also has the advantages of compact structure, small size, light weight, low exhaust temperature, little oil leakage, smooth starting and high charging speed, and is convenient to mount and arrange.

Description

technical field [0001] The present invention relates to automobile air compression equipment, in particular to an electric-driven air compressor for a vehicle, a pneumatic system for a vehicle comprising the air compressor electrically driven, and a vehicle comprising the pneumatic system. Background technique [0002] Automobile air compressors are mainly used to provide the necessary air source for automobile braking system, suspension system, door opening and closing and other auxiliary pneumatic devices. Existing automotive air compressors include volumetric compressors, reciprocating compressors, centrifugal compressors, etc. Most of the commonly used compressors are reciprocating compressors, that is, piston compressors. Internal reciprocating movement, its own structure is relatively cumbersome, and it occupies a relatively large space. For example, the application number is: 200620104693.X, a utility model patent named "Automobile Brake Air Compressor", which uses t...

Problems solved by technology

Existing automotive air compressors include volumetric compressors, reciprocating compressors, centrifugal compressors, etc. Most of the commonly used compressors are reciprocating compressors, that is, piston compressors. Internal reciprocating movement, its own structure is relatively cumbersome, and it occupies a relatively large space

For example, the application number is: 200620104693.X, a utility model patent named "Automobile Brake Air Compressor", which uses the automobile engine to provide power for the compressor, and the power of the engine is transmitted to the air compressor through the power wheel, suction cup, and fixed disk The power shaft has complex connection structure, large volume, frequent clutch action and easy loss, high failure rate and high maintenance cost

For example, the application number is: 201010165319.1 invention patent, named "energy-saving automotive water-cooled air compressor", using a special water-cooling system to increase the cooling area in the exhaust chamber to achieve effective exhaust cooling, but in terms of compressor structure There is still the problem that the volume is large, which is not conducive to the installation and layout in the car
