Abstract
A vehicle is provided with a transmission having an inductor assembly. The inductor assembly is mounted within the transmission such that it is directly cooled by transmission fluid through at least one of spraying, splashing and immersion. The transmission includes at least one gear that is configured to, when rotating, transmit torque between an input and output of the transmission and splash fluid onto the inductor assembly to cool the inductor assembly.
Claims13
A transmission comprising:
- a housing;
- and
- a cylindrical inductor assembly disposed within the housing and including a coil having exposed exterior surface area portions and a core formed onto the coil such that at least a portion of the exterior surface area portions is exposed to fluid within the transmission to cool the coil;
- and
- at least two intermediate gears rotatably coupled to the transmission and disposed within a chamber defined by the transmission, the intermediate gears being in contact with the fluid and configured to displace a portion of the fluid onto the cylindrical inductor assembly during rotation, wherein the intermediate gears are configured to mechanically connect an engine and at least one electric machine oriented axially adjacent to the engine, to a driveshaft.
