Abstract
A power and cooling assembly is disclosed for use with a vehicle having a deck for a rotatable tool such as a mowing blade. An electric motor is mounted on the deck and used to drive the blades by an output shaft. A circulating pump is connected to a housing of the electric motor and is also driven by the electric motor. The circulating pump is hydraulically connected to at least one sump on the vehicle and at least one electrical component of the vehicle to provide cooling thereto. Additional cooling pumps may be provided on the vehicle and may provide cooling to additional electrical components.
Claims20
A power and cooling assembly for use with a vehicle having a deck for at least one rotatable tool, the power and cooling assembly comprising:
- an electric motor mounted on the deck and used to drive the at least one rotatable tool, the electric motor comprising a motor housing and an output shaft;
- and
- a circulating pump connected to the motor housing and driven by the output shaft of the electric motor, the circulating pump capable of being hydraulically connected to at least one sump and at least one electrical component of the vehicle.
A vehicle, comprising:
- a prime mover disposed on the vehicle and driving an output shaft;
- a deck mounted on the vehicle and having a plurality of mowing blades disposed thereunder;
- a pair of power transfer mechanisms disposed on the vehicle, each power transfer mechanism being connected to and driving one of a pair of driven wheels of the vehicle;
- an electric motor mounted on the deck and driving one of the plurality of mowing blades, the electric motor comprising a motor housing;
- and
- a first circulating pump mounted to the motor housing and hydraulically connected to at least one electrical component of the vehicle to provide coolant fluid to the at least one electrical component.
A power and cooling system for a vehicle having a prime mover disposed on a frame, an output shaft driven by the prime mover, a pair of driven wheels, and a deck for at least one rotatable tool, the power and cooling system comprising:
- a pair of power transfer mechanisms disposed on the vehicle, each power transfer mechanism being connected to and driving one of the pair of driven wheels;
- an electric motor comprising a motor housing and connected to and driving the at least one rotatable tool;
- and
- a first circulating pump engaged to the motor housing and hydraulically connected to at least one electrical component of the vehicle to provide coolant fluid to the at least one electrical component.
