Abstract
An integrated electric power take-off includes an electric motor that is driven by an electric motor of an electric vehicle, a hydraulic pump or a similar device that is adapted to operate a rotatably driven accessory provided on the electric vehicle, and a geartrain system connected between the electric motor and the hydraulic pump. The geartrain system is an integral portion of the integrated electric power take-off that permits an optimal selection of the electric motor and the hydraulic pump to be made for each specific application.
Claims20
An integrated electric power take-off comprising:
- an electric motor portion that is adapted to be operated by an electric motor of an electric vehicle;
- an output portion that is adapted to operate a rotatably driven accessory provided on the electric vehicle;
- a geartrain portion connected between the electric motor portion and the output portion, wherein when the electric motor portion is operated by the electric motor of the electric vehicle, the geartrain portion operates the output portion to operate the rotatably driven accessory provided on the electric vehicle;
- and
- a lubricant and coolant flow system including a fluid pump adapted to circulate fluid from a sump through a first cooling structure supported adjacent to the electric motor portion and through a second cooling structure supported adjacent to the geartrain portion, and back to the sump.
A method of manufacturing an integrated electric power take-off comprising the steps of:
- (a) providing an electric motor portion that is adapted to be operated by an electric motor of an electric vehicle;
- (b) providing an output portion that is adapted to operate a rotatably driven accessory provided on the electric vehicle;
- (c) providing a geartrain portion having a gear ratio that is optimized for use in a given application for the integrated electric power take-off;
- (d) connecting the geartrain portion between the electric motor portion and the output portion, wherein when the electric motor portion is operated by the electric motor of the electric vehicle, the geartrain portion operates the output portion to operate the rotatably driven accessory provided on the electric vehicle;
- and
- (e) providing a lubricant and coolant flow system including a fluid pump adapted to circulate fluid from a sump through a first cooling structure supported adjacent to the electric motor portion and through a second cooling structure supported adjacent to the geartrain portion, and back to the sump.
An integrated electric power take-off comprising:
- a housing;
- an electric motor portion disposed within the housing and adapted to be operated by an electric motor of an electric vehicle;
- an output portion adapted to operate a rotatably driven accessory provided on the electric vehicle;
- a geartrain portion disposed within the housing and connected between the electric motor portion and the output portion, wherein when the electric motor portion is operated by the electric motor of the electric vehicle, the geartrain portion operates the output portion to operate the rotatably driven accessory provided on the electric vehicle;
- and
- an inverter disposed within the housing, wherein locating the inverter within the housing with the electric motor portion and the geartrain portion reduces electromagnetic interference.
