Torque converter cover for supplying cooling to a hybrid electric motor
A cover for a torque converter and an electric motor, comprising a cover surface that includes a first cluster of perforations that are located adjacent to a first end of a rotor of the motor, wherein the perforations are arranged to transfer fluid from the torque converter to a rotor of the electric motor.
1. A torque converter cover, comprising:
a cover surface of the torque converter cover in a torque converter, the cover surface including a plurality of perforations configured to allow a flow of transmission fluid on an electric motor, wherein the plurality of perforations includes a first cluster of multiple perforations that are located radially adjacent to a first end of a rotor of the electric motor, and a second cluster of multiple perforations that are located radially adjacent to a second end of the rotor.
2. The torque converter cover of claim 1 , wherein the perforations are configured to allow at least one liter of transmission fluid onto the electric motor per minute.
3. The torque converter cover of claim 1 , wherein the perforations are configured to spray at least one liter of transmission fluid onto an electric motor per minute.
4. The torque converter cover of claim 1 , wherein the first cluster is adjacent to a drive plate connected to the torque converter.
5. The torque converter cover of claim 1 , wherein the perforations are configured to spray fluid radially onto a stator of the electric motor.
6. The torque converter cover of claim 1 , wherein the plurality of perforations are each individually between 0.5 millimeter to one millimeter in diameter.
7. The torque converter cover of claim 1 , wherein the perforations are configured to cool between 0.5 liters per minute to 2 liter per minute.
8. The torque converter cover of claim 1 , wherein the torque converter cover is utilized in the torque converter of a P1-hybrid configuration that includes a direct connection with a crankshaft of the internal combustion engine.
9. The torque converter cover of claim 1 , wherein the torque converter cover is utilized in the torque converter of a P2-hybrid configuration.
10. The torque converter cover of claim 1 , wherein the perforations are configured to spray fluid on both a stator of the electric motor and the rotor of the electric motor.
11. The torque converter cover of claim 1 , wherein the perforations are configured to spray fluid onto a stator of the electric motor.
