Abstract
An auxiliary power system for delivering power to the fan hub of a vehicle engine and to the air conditioning compressor and alternator of the vehicle is provided. The system includes an auxiliary engine which powers an hydraulic pump. Hydraulic fluid is directed from the hydraulic pump to an hydraulic motor under pressure. A first clutch assembly is provided in order to engage and disengage the hydraulic motor from the fan hub of the vehicle. A second clutch assembly is provided in order to engage and disengage the crankshaft from the primary engine of the vehicle.
Claims20
An auxiliary power system for causing the rotation of a fan hub of a motor of a vehicle during periods of shutdown of said motor, said fan hub being capable of driving an air conditioning compressor and an alternator mounted in said vehicle, comprising:
- an auxiliary engine;
- an hydraulic pump, said hydraulic pump being mechanically connected to said auxiliary engine whereby said auxiliary engine causes the operation of said pump, said pump being fluidly connected to a reservoir of hydraulic fluid;
- an outgoing hydraulic line capable of delivering pressurized hydraulic fluid from said hydraulic pump to an hydraulic motor;
- an incoming hydraulic line capable of delivering hydraulic fluid from said hydraulic motor to said hydraulic pump;
- a first clutch assembly, said clutch assembly being capable of selectively coupling said hydraulic motor to said fan hub of said vehicle whereby power from said auxiliary engine causes said fan hub to rotate when said clutch assembly couples said hydraulic motor to said fan hub, and whereby said air conditioner compressor and said alternator are driven by said auxiliary engine;
- and
- a second clutch assembly, said second clutch assembly being capable of selectively coupling said motor to said fan hub whereby said second clutch assembly causes said motor to disengage from said fan hub when said first clutch assembly causes said hydraulic motor to be coupled to said fan hub.
The auxiliary power system of claim I further comprising an auxiliary coolant system, said auxiliary coolant system comprising a first coolant tube and a second coolant tube, said first coolant tube having a first end and a second end, said first end of said first coolant tube mounted in fluid communication with said auxiliary engine and said second end of said first coolant tube mounted in fluid communication with said motor and said second coolant tube having a first end and a second end, said first end of said second coolant tube mounted in fluid communication with said motor and said second end of said second tube mounted in fluid communication with said auxiliary engine whereby coolant can be circulated through said auxiliary engine and said motor through said first coolant tube and said second coolant tube.
An auxiliary power system for causing the rotation of a fan hub of a motor of a vehicle during periods of shutdown of said motor, said fan hub being capable of driving an air conditioning compressor and an alternator mounted in said vehicle, comprising:
- an auxiliary engine;
- an hydraulic pump, said hydraulic pump being mechanically connected to said auxiliary engine whereby said auxiliary engine causes the operation of said pump, said pump being fluidly connected to a reservoir of hydraulic fluid;
- an outgoing hydraulic line capable of delivering pressurized hydraulic fluid from said hydraulic pump to an hydraulic motor;
- an incoming hydraulic line capable of delivering hydraulic fluid from said hydraulic motor to said hydraulic pump;
- a first clutch assembly, said clutch assembly being capable of selectively coupling said hydraulic motor to said fan hub of said vehicle whereby power from said auxiliary engine causes said fan hub to rotate when said clutch assembly couples said hydraulic motor to said fan hub, and whereby said air conditioner compressor and said alternator are driven by said auxiliary engine;
- a second clutch assembly, said second clutch assembly being capable of selectively coupling said motor to said fan hub whereby said second clutch assembly causes said motor to disengage from said fan hub when said first clutch assembly causes said hydraulic motor to be coupled to said fan hub;
- and
- an auxiliary coolant system, said auxiliary coolant system comprising a first coolant tube and a second coolant tube, said first coolant tube having a first end and a second end, said first end of said first coolant tube mounted in fluid communication with said auxiliary engine and said second end of said first coolant tube mounted in fluid communication with said motor and said second coolant tube having a first end and a second end, said first end of said second coolant tube mounted in fluid communication with said motor and said second end of said second tube mounted in fluid communication with said auxiliary engine whereby coolant can be circulated through said auxiliary engine and said motor through said first coolant tube and said second coolant tube.
An auxiliary power system for causing the rotation of a fan hub of a motor of a vehicle during periods of shutdown of said motor, said fan hub being capable of driving an air conditioning compressor and an alternator mounted in said vehicle, comprising:
- an auxiliary engine;
- an hydraulic pump, said hydraulic pump being mechanically connected to said auxiliary engine whereby said auxiliary engine causes the operation of said pump, said pump being fluidly connected to a reservoir of hydraulic fluid;
- an outgoing hydraulic line capable of delivering pressurized hydraulic fluid from said hydraulic pump to an hydraulic motor;
- an incoming hydraulic line capable of delivering hydraulic fluid from said hydraulic motor to said hydraulic pump;
- a first electromechanical clutch assembly, said first clutch assembly being capable of selectively coupling said hydraulic motor to said fan hub of said vehicle whereby power from said auxiliary engine causes said fan hub to rotate when said clutch assembly couples said hydraulic motor to said fan hub, and whereby said air conditioner compressor and said alternator are driven by said auxiliary engine, said first clutch including a first fail safe mechanism, said first fail safe mechanism comprising a sensor for sensing pressure within said outgoing hydraulic line and a signal generating control whereby said signal generating control enables operation of said first clutch when said sensor senses pressure within said outgoing hydraulic line greater than a predetermined minimum pressure;
- a second clutch assembly, said second clutch assembly said second clutch assembly being capable of selectively coupling said motor to said fan hub whereby said second clutch assembly causes said motor to disengage from said fan hub when said first clutch assembly causes said hydraulic motor to be coupled to said fan hub;
- and
- an auxiliary coolant system, said auxiliary coolant system comprising a first coolant tube and a second coolant tube, said first coolant tube having a first end and a second end, said first end of said first coolant tube mounted in fluid communication with said auxiliary engine and said second end of said first coolant tube mounted in fluid communication with said motor and said second coolant tube having a first end and a second end, said first end of said second coolant tube mounted in fluid communication with said motor and said second end of said second tube mounted in fluid communication with said auxiliary engine whereby coolant can be circulated through said auxiliary engine and said motor through said first coolant tube and said second coolant tube.
