ASSEMBLY COMPRISING A GENERATOR AND ELECTRIC MOTORS, FOR A VEHICLE COOLING OR AIR-CONDITIONING SYSTEM

摘要

An assembly including: a diesel heat engine driving a compressor; a generator having permanent magnets and a four-pole rotor, the generator shaft being rotated by the heat engine via a belt pulley system; one or more electric motors for the condenser(s) and/or evaporator(s) of a vehicle cooling or air-conditioning system, the generator directly powering the motor(s) and the supply voltage of the motor(s) being the generator output voltage; an auxiliary electric motor for driving the compressor when it is not or cannot be driven by the heat engine; and a device for toggling the power supply of the electric motor(s) of the condenser(s) and/or evaporator(s) of the cooling or air-conditioning system, by which it is possible to switch from power being supplied by the generator to an external electric network, said toggle device including one or more switches for controlling the power supply of the motor(s) from the electric network.

1. An assembly comprising:
a diesel internal combustion engine driving a compressor, a generator with permanent magnets, the four-pole rotor and shaft of which are driven in rotation by the internal combustion engine via a belt-pulley system, one or more electric motors for the condenser(s) and/or evaporator(s) of a vehicle cooling or air-conditioning system, the generator powering the electric motor(s) directly, the supply voltage of the electric motor(s) being the generator output voltage, an auxiliary electric motor for driving the compressor when the latter is not or cannot be driven by the internal combustion engine, a device for switching the power supply of the electric motors of the condenser(s) and/or evaporator(s) of the cooling or air-conditioning system, allowing switching from supply by the generator to supply by an external electrical network, the switching device comprising one or more switches allowing the supply of the electric motors to be controlled from the electrical network.
