Vehicle air compressor and intelligent air supply system device thereof

Abstract

The invention provides a vehicle air compressor and an intelligent air supply system device thereof. The vehicle air compressor is characterized in that the vehicle air compressor is provided with a driving gear (2) and a driven gear (11) which are a pair of gears with the same tooth number, the driving gear (2) is driven by a motor (58), and the driving gear (2) is meshed with the driven gear (11) with the same tooth number, so that two crankshaft connecting rod mechanisms are driven to rotate oppositely, under the driving of the two crankshaft connecting rod mechanisms which rotate oppositely, two pistons of a high-pressure piston group and a low-pressure piston group realize alternate up-and-down reciprocating motion; the pair of gears with the same tooth number are arranged on a main journal (64) of a crankshaft (4), and the crankshaft (4) adopts the double-point supported crankshaft (4) and a maintenance-free bearing (5) which is located at an eccentric crankshaft journal (62) ofthe crankshaft (4). The intelligent air supply system device has the advantages of small vibration, low noise, long service life, high protection level, intelligent control, compact structure, convenience in installation and arrangement and the like.

Description

technical field [0001] The invention relates to automobile air compression equipment and an air supply system device thereof, in particular to an automobile air compressor and an intelligent air supply system thereof. Background technique [0002] Automotive air compressors are mainly used to provide the necessary air source for automotive braking technology systems, suspension systems, door opening and closing, and auxiliary pneumatic devices. The air source device of the whole vehicle is composed of multiple components. The controller (for example, inverter, etc.) provides power and controls the operation of the electric air compressor. , electronically controlled drier 52, etc.) to cool down the compressed air, dry and drain water, and the whole system is bulky. At present, electric air compressors for vehicles mainly include vane type, screw type, scroll type, and piston type air compressors.

AI Technical Summary

Problems solved by technology

Therefore, the oil-free reciprocating piston air compressor needs to use maintenance-free bearings due to its own structure without lubricating oil, and it is difficult to insert maintenance-free bearings at the crank, so most of them adopt a single-crank cantilever structure for easy installation. into maintenance-free bearings, resulting in poor structural strength

In addition, although a few technical solutions do not use a single-crank cantilever structure but a non-cantilever structure, in order to allow the bearing to be inserted into the crank throw from the end and press-fitted on the crank during assembly, some of them have designed long crankshafts with gentle slopes. Span crank leads to bulky volume

In order to ensure that the bearing can be press-fitted on the crank during assembly, a split crank is also used in theory. However, if a split crank is used, it is difficult to ensure the integrity of the processing and assembly and the shape and position tolerance is too large, resulting in poor performance and life.

[0005] In addition, at present, the internal temperature of most air-cooled air compressors is difficult to derive, and the exhaust temperature is high, which is difficult to meet the requirements of continuous operation.

The higher the temperature of the gas, the more difficult it is to be compressed, resulting in low compression efficiency and high power consumption
