Abstract

The invention discloses a stepless speed regulation reciprocating piston compressor suitable for a new energy automobile. The stepless speed regulation reciprocating piston compressor comprises a cylinder body, a driving shaft, a driven shaft, a compression mechanism and a speed regulation mechanism. The driving shaft and the driven shaft are coaxially installed on the two sides of the cylinder body. The compression mechanism comprises a crankshaft, a first connecting rod and a second connecting rod, the two ends of the crankshaft are installed in the driving shaft and the driven shaft respectively, one end of the first connecting rod is installed on the surface of the crankshaft, the other end of the first connecting rod is connected with a first piston, and one end of the second connecting rod is installed on the surface of the crankshaft, and the other end of the second connecting rod is connected with a second piston. The first piston and the second piston are arranged at the two ends of the cylinder body respectively. The speed adjusting mechanism is installed in the driven shaft and can adjust the distance between the central axis of the crankshaft and the central axis of the driven shaft. The stepless speed regulation reciprocating piston compressor is simple in structure and convenient to operate so as to achieve the purpose of stepless speed regulation, and running of an automobile under different working conditions is met.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a reciprocating piston compressor with stepless speed regulation suitable for new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as the power source, or the use of conventional vehicle fuels, the adoption of new vehicle power devices, and the comprehensive vehicle power control and advanced technology in driving, forming advanced technical principles and new features. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles and hydrogen engine vehicles. [0003] In order to improve the comfort system of new energy vehicles, it is necessary to install an air conditioning system, which includes a compressor device. The existing plug compressor is directly driven by a motor during operation, which cannot meet the oper...
