Problems solved by technology

[0002]The connection between the existing vehicle air-conditioning compressor and the output shaft of the engine is mainly through a pulley and a belt. Electromagnetic clutch and clutch coil. When the clutch coil is energized, the end face of the pulley of the electromagnetic clutch is engaged with the clutch suction cup to drive the main shaft of the compressor to rotate. The frequent suction of the clutch suction cup will generate axial impact on the main shaft of the car air-conditioning compressor. The electromagnetic clutch The clutch coil and clutch coil are prone to failure, and the belt connection method has disadvantages such as uncompact installation, low mechanical efficiency, and easy wear of the belt; in addition, an existing engine is only connected to one vehicle air-conditioning compressor, which cannot drive multiple vehicle air-conditioning compressors. Air-conditioning compressor

The driving gear meshes with the driven gear. The fixing hole connected to the engine cylinder block, the positioning hole connected to the front end cover of the compressor, the bearing hole is formed on the connecting cover, the bearing is installed inside, the bearing is connected to the head of the engine output shaft, and the gearbox body is connected to the engine side cover The connecting hole of the driven gear, the center hole of the driven gear is connected with the main shaft of the compressor, the cylindrical surface of the other end of the driven gear is matched with the inner hole of the bearing, the bearing is fixedly installed on the gearbox body, and the center hole of the driving gear is fixed with the output shaft of the engine connect. The invention has the advantages of compact structure, convenient installation, good reliability and high mechanical efficiency.

Description

technical field [0001] The invention belongs to a connection device between an engine and a vehicle air-conditioning compressor, in particular to a variable-speed direct connection device between an engine and multiple vehicle air-conditioning compressors. Background technique [0002] The connection between the existing vehicle air-conditioning compressor and the engine output shaft is mainly through a pulley and a belt. The vehicle air-conditioning compressor of this connection needs to be equipped with an electromagnetic clutch and a clutch coil. When the clutch coil is energized, the pulley of the electromagnetic clutch The end face is attracted to the clutch suction cup to drive the compressor shaft to rotate. Frequent clutch suction will generate axial impact on the main shaft of the vehicle air-conditioning compressor. The electromagnetic clutch and clutch coil are prone to failure. Disadvantages such as compactness, low mechanical efficiency, and easy wear of the bel...
