Abstract
In a hybrid compressor for a vehicle where a vehicle engine is stopped when the vehicle is temporally stopped, a pulley, a motor and a compressor can be driven in independent from each other, and are connected to a sun gear, planetary carriers and a ring gear of a planetary gear. A rotational speed of the motor is adjusted by a controller, so that a rotational speed of the compressor is changed with respect to a rotational speed of the pulley. Accordingly, production cost of the hybrid compressor and the size thereof can be reduced, while a cooling function can be ensured even when the vehicle engine is stopped.
Claims18
A hybrid compressor device for a vehicle having an engine that is stopped when the vehicle is temporally stopped, the hybrid compressor device comprising:
- a pulley rotated by the engine;
- a motor rotated by electric power from a battery of the vehicle;
- a compressor for compressing refrigerant in a refrigerant cycle system, the compressor being operated by driving force of the pulley and driving force of the motor;
- and
- a transmission mechanism connected respectively independently to a rotational shaft of the pulley, a rotational shaft of the motor and a rotational shaft of the compressor, the transmission mechanism being provided for changing a rotational speed of the pulley and a rotational speed of the motor, to be transmitted to the compressor, wherein:
- the pulley, the motor and the compressor are disposed to be rotatable independently;
- and
- the rotational speed of the compressor is changed by adjusting the rotational speed of the motor with respect to the rotational speed of the pulley.
A hybrid compressor device for a vehicle having an engine that is stopped in a predetermined running condition of the vehicle, the vehicle including a driving motor for driving the vehicle, the hybrid compressor device comprising:
- a pulley rotated by the engine;
- a motor rotated by electric power from a battery of the vehicle;
- a compressor for compressing refrigerant in a refrigerant cycle system, the compressor being operated by driving force of the pulley and driving force of the motor;
- a transmission mechanism connected respectively independently to a rotational shaft of the pulley, a rotational shaft of the motor and a rotational shaft of the compressor, the transmission mechanism being provided for changing at least one of rotational speeds of the pulley, the motor and the compressor, to be transmitted to at least the other one of the pulley, the motor and the compressor;
- and
- a control unit for adjusting the rotational speed of the motor, wherein:
- the pulley, the motor and the compressor are disposed to be rotatable independently;
- and
- the control unit changes the rotational speed of the compressor, by adjusting the rotational speed of the motor with respect to the rotational speed of the pulley.
