Abstract
A cooling system for an electrically variable transmission includes an electric motor having a plurality of connectors. The plurality of connectors are each assembled within a plurality of connector openings in a terminal block. Fluid from within a passageway is supplied by a pressurized fluid source, and an orifice for the passageway is located adjacent to one of the plurality of connector opening. The fluid flowing from the passageway is directed onto one of the plurality of connectors.
Claims16
A cooling system for an electrically variable transmission comprising:
- a first electric motor having a first plurality of connectors;
- a first terminal block defining a first plurality of connector openings, wherein the first plurality of connectors are each assembled within a respective one of the first plurality of connector openings;
- a first component defining a first passageway and a first orifice, wherein fluid in the first passageway is supplied by a first pressurized fluid source;
- and
- wherein the first orifice is located adjacent to one of the first plurality of connector openings, such that fluid flowing from the first passageway is directed onto one of the first plurality of connectors.
A method for cooling an electric motor within an electrically variable transmission comprising:
- directing pressurized fluid from a main transmission cooling system through first passageway formed in a first transmission component onto a first plurality of connectors for a first electric motor.
A method for cooling a plurality of electric motors comprising:
- directing pressurized fluid from a cooling system through first passageway formed in a first component onto a first plurality of connectors for a first electric motor;
- and
- directing pressurized fluid from a cooling system through second passageway formed in a second component onto a second plurality of connectors for a second electric motor.
