Air source system of water-cooling air compressor for vehicles

Abstract

The invention discloses an air source system of a water-cooling air compressor for vehicles. The air source system comprises a double-crank inner support transmission structure, a controller and a water-cooling system, wherein the double-crank inner supporting transmission structure is driven by a motor, an elastic coupler and a crankshaft, cranks on the two sides of the crankshaft drive a low-pressure cylinder piston assembly and a high-pressure cylinder piston assembly to reciprocate up and down, and the gas compression process is completed; the controller is fixed on the motor, a labyrinthtype cooling water channel is arranged in the controller, and the controller shares the working state of an air supply system and feeds back fault information in real time; and the water cooling system is supplied with water by a whole vehicle water pump system, enters a crankcase water tank after passing through the labyrinth type cooling water channel in the controller, then enters a cylinder cover after passing through a water tank in a piston cylinder, returns to the piston cylinder and a crankcase again after passing through a water channel in an inner cavity of the cylinder cover, and isfinally discharged and converged into a whole vehicle circulating water channel. The air source system has the advantages of being high in compression efficiency, small in vibration, low in noise, long in service life, clean in air source, efficient, energy-saving, compact in structure, small in size, convenient to install and arrange and the like.

Description

technical field [0001] The invention relates to the field of air compression equipment for automobiles, in particular to an air source system for a water-cooled air compressor for automobiles. Background technique [0002] Since the oil-free reciprocating piston air compressor has no lubricating oil inside, the kinematic pair of the connecting rod and the crank must be carried by maintenance-free bearings. Due to its own oil-free lubrication structure, it is difficult to Maintenance-free bearings are inserted, so most oil-free piston air compressors currently adopt a single-crank cantilever structure, which has a long fulcrum, poor structural strength, and large operating vibration. The double-crank transmission structure is supported inside, and maintenance-free double-row bearings are used between the two piston-connecting rod groups to support and place on the crankshaft to ensure the reliable strength and stable operation of the transmission structure. At the same time,...

Problems solved by technology

[0004]1. Most of the commonly used car air compressors on the market are air-cooled air compressors, which have high exhaust temperature, and the high internal temperature is difficult to export and affect various components The service life of the compressor cannot meet the requirements of continuous operation; and the higher the temperature of the gas, the more difficult it is to be compressed, resulting in low compression efficiency and increased power consumption, while some water-cooled compressors have poor water channel sealing structure, serious water leakage, and poor reliability

[0005]2. The oil-free reciprocating piston air compressor is limited by its own oil-free transmission structure. The transmission structure is bulky and the vibration is large, which affects the comfort of the vehicle.

The vehicle controller is usually an all-in-one controller, which is bulky and requires additional space for installation and arrangement; at the same time, if a single function of the controller is damaged, the entire controller assembly needs to be replaced, and the maintenance cost is high
