AI Technical Summary

Problems solved by technology

The air compressor of the present invention also effectively solves the problems of large deviation of the shape and position of the two cranks caused by processing and assembly errors of the split crankshaft transmission parts, resulting in large operating vibration and low life. The volume and weight of the machine are greatly reduced, and the magnetic drive fan is used to completely isolate the inside of the crankcase. The whole machine reaches the IP68 protection level, and no external power supply is required to control the cooling fan, which improves the reliability of the whole machine

Embodiment Construction

[0043] The following description is merely exemplary in nature and not intended to limit the disclosure, application or use. The specific implementation of the vehicle-mounted electric-driven oil-free air compressor of the present invention will be further described below in conjunction with the accompanying drawings.

[0044] Such as Figure 1-Figure 3 Shown is a schematic structural view of the vehicle-mounted electric-driven oil-free air compressor according to the present invention.

[0045] A vehicle-mounted electric-driven oil-free air compressor of the present invention includes a high-efficiency motor 29, a crankshaft 19, a crankcase 22 and a piston cylinder 3. The driving end 26 of the shaft coupling flexibly drives the crankshaft 19 to rotate; the rear side crank of the crankshaft 19 is the driven end 24 of the coupling; the crank on the crankshaft 19 is provided with a high-pressure piston assembly 5 and a low-pressure piston assembly 41, and placed on the same sid...

Abstract

The invention relates to a vehicle-mounted electric drive oil-free air compressor. The vehicle-mounted electric drive oil-free air compressor comprises an efficient motor (29), a crankshaft (19), a crankshaft box (22) and a piston cylinder (3); an efficient motor (29) flexibly drives the crankshaft (19) to rotate through an internal coupler driving end (26), an elastic body (25) and a coupler driven end (24), the rear side crank of the crankshaft (19) is the coupler driven end (24), a high-pressure piston assembly (5) and a low-pressure piston assembly (41) are arranged on the crank of the crankshaft (19), and are placed in a hole of the piston cylinder (3) in a same side manner. The whole machine size and weight are greatly reduced, the axial distance of the two connecting rods and a crankshaft bearing can be shortened, in addition, a magnetic force transmission fan is adopted and is completely isolated from the interior of the crankshaft box, the whole machine reaches IP68 protectionlevel, a cooling fan can be controlled without external power supply, and the whole machine reliability is improved.

Description

technical field [0001] The invention relates to vehicle air compression equipment, in particular to a vehicle-mounted electric-driven oil-free air compressor. Background technique [0002] Automotive air compressors are mainly used to provide necessary air sources for automotive braking technology, suspension systems, door opening and closing, and auxiliary pneumatic devices. At present, the air compressors for vehicles mainly include vane type, screw type, scroll type, and piston type air compressors. The general working pressure is too low. An external independent cooling fan is required, and power supply is required to control the start and stop, which has low reliability and poor life. The oil air compressor is bulky and difficult to arrange. [0003] For example, the Chinese invention patent with the publication number CN101614200A discloses an oil-free compressor for locomotives, including motors, cylinders, piston rod assemblies, air valve assemblies, cooling fans a...
