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.
Claims20
A vehicle comprising:
- a transmission defining a chamber and including an inductor assembly and at least one gear mounted proximate to each other within the chamber, the at least one gear adapted to, when rotating, transmit torque between an input and output of the transmission and splash fluid directly onto the inductor assembly to cool the inductor assembly;
- wherein the inductor assembly comprises an insulator, a coil wound around the insulator and having exposed surface area portions, and a core formed in a generally planar shape and supported by the insulator, and
- wherein the inductor assembly is mounted within an intermediate region of the chamber between an upper region and a lower region, and the fluid accumulates in the lower region and wherein the vehicle further comprises a nozzle disposed in the intermediate region.
A transmission comprising:
- a housing defining a chamber;
- a planar inductor assembly (i) including an insulative bobbin, a coil wound around the insulative bobbin and having exposed surface area portions, and a core supported by the insulative bobbin and (ii) disposed within the chamber of the housing such that at least a portion of the exposed surface area portions is exposed to fluid within the chamber to cool the coil, wherein the planar inductor assembly is mounted within an intermediate region of the chamber between an upper region and a lower region, and wherein the fluid accumulates in the lower region;
- and
- at least one element rotatably mounted within the chamber and proximate to the planar inductor assembly, wherein the at least one element is in contact with the fluid and adapted to displace a portion of the fluid directly onto the planar inductor assembly during rotation.

A transmission comprising:
- a housing defining a chamber;
- an inductor assembly disposed within the chamber of the housing;
- and
- at least one element disposed within the chamber and proximate to the inductor assembly, wherein the at least one element is adapted to, when rotating, transmit torque between an input and output of the transmission and displace cooling fluid directly onto the inductor assembly, wherein the chamber comprises an upper region, a lower region, and an intermediate region between the upper region and lower region, wherein the inductor assembly is mounted within the intermediate region and the cooling fluid accumulates in the lower region.
