Composite auxiliary machine for vehicle and control unit thereof

Abstract

A composite auxiliary machine for a vehicle and an accompanying control unit to control a compressor. The composite auxiliary machine for a vehicle includes a compressor for compressing refrigerant, a rotary machine that acts as an electric motor and a generator, and a torque and power distributing mechanism for distributing engine torque and power from a drive shaft to a compressor shaft and a rotary machine shaft, and from the rotary machine shaft to the drive shaft and compressor shaft. An intermittent mechanism is provided to the torque and power distributing mechanism so as to connect and disconnect any two of the drive shaft, the compressor shaft, and the rotary machine shaft. A locking mechanism is provided for restricting rotation of the compressor shaft. The compressor includes variable displacement mechanism for varying the amount of discharge per turn of the compressor shaft.
