Abstract

The invention discloses a piston type air compressor, an air supply system and an automobile. The piston type air compressor comprises a crankshaft, a piston connecting rod assembly and an air cylinder assembly. The piston and connecting rod assembly comprises a first piston and connecting rod set and a second piston and connecting rod set which are arranged in the circumferential direction of thecrankshaft in a spaced mode and each comprise a connecting rod and a piston, wherein one end of the connecting rod is arranged on the crankshaft in a sleeving mode, and the other end of the connecting rod is connected with the piston. The air cylinder assembly comprises a first air cylinder and a second air cylinder which are arranged in the circumferential direction of the crankshaft in a spacedmode. The pistons of the first piston and connecting rod set and the second piston and connecting rod set are located in the first air cylinder and the second air cylinder separately and can reciprocate in the corresponding air cylinders along with rotation of the crankshaft. When the piston of one piston and connecting rod set of the piston and connecting rod assembly is located in an air sucking working stroke, the piston of the other piston and connecting rod set is located in an air exhausting working stroke. The piston type air compressor can continuously supply air, and air exhausting impulse and vibration are reduced.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to a piston air compressor, an air supply system and a vehicle. Background technique [0002] An air compressor is a device that converts mechanical energy into gas pressure energy. The existing air compressors can be divided into three categories: volumetric, dynamic, and thermal compressors according to their working principles. Among them, piston air compressors are used as volumetric air compressors. The most common form of compressor, with the longest research time and the most mature technology, is the mainstream model of small volumetric air compressors, widely used in automotive engine refrigeration, door switches, etc., so it has broad application prospects. [0003] The working principle of the piston air compressor is to drive the crankshaft to rotate, so that the piston in the cylinder reciprocates with the rotation of the crankshaft, thereby compressing the gas ...
