Abstract

The invention relates to a horizontal-type piston-type two-stage air compressor used for a vehicle. The horizontal-type piston-type two-stage air compressor used for the vehicle comprises a horizontally arranged crankcase, and a piston cylinder is placed on one side of the crankcase; a rear end cover is connected to the tail portion of the crankcase, and a motor is fixed to the tail portion of therear end cover; a motor spindle is connected with a double-crank crankshaft through an elastic coupling; a high-pressure cylinder piston connecting rod assembly and a low pressure piston connecting rod assembly are correspondingly connected to left-right symmetrically arranged cranks of the crankshaft; and a low-pressure cylinder vent pipe is arranged on the outer side of a cylinder head; a middle cold air outlet pipe is connected with the high pressure area of the cylinder head; and compressed air after cooling enters the cylinder through a high-pressure air inlet valve piece on a valve plate, and secondary compression is completed under combined action of the high-pressure cylinder piston and an air exhaust valve piece. According to the horizontal-type piston-type two-stage air compressor used for the vehicle, the small-sized lightweight two-stage piston type air compressor can meet high pressure demands of the vehicle, working pressure can reach above 1.5 MPa, air is clean, operation is smooth, air pumping efficiency is high, the size is small, the weight is small, the life is long, and mounting and arranging are convenient.

Description

technical field [0001] The invention relates to an automobile air compression device, in particular to a horizontal piston type two-stage air compressor for automobiles. 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, piston type air compressors, etc., the general working pressure is too low, and most of the commonly used compressors are oil-filled air compressors, and the air source is polluted by oil. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a small and lightweight two-stage piston air compressor that can meet the high-pressure requirements of vehicles. Small size, light weight, long life, easy to install and arrange horiz...
