International Classification:

B60W 10/196

US Classification:

1922195

Abstract:

A park lock of a transmission, including a park gear; a park pawl rotating about a pawl shaft, the park pawl having a pawl portion locking the park gear, the park pawl including a cam contact portion; a park rod responsive to an operation of a controller, the park rod having a cam portion pressing the cam contact portion to have park pawl engage the park gear; a park sleeve receiving the cam portion and defining a first contact point providing a reactive force to the cam contact portion of the park pawl pressing against the cam portion at a second contact point; a pawl torsional spring biasing the park pawl towards disengagement; and a pawl stopper limiting the rotation of the park pawl wherein motions are constrained within a plane of the transmission and components are rotatingly disposed in parallel axis bores in one half of a transmission case.

Assignee:

Tesla Motors, Inc. - Palo Alto CA

International Classification:

H02K 9/193
F16H 57/04
H02K 7/116

Abstract:

A liquid cooling system for an electric motor includes: a pump for liquid to cool the electric motor; a heat exchanger that removes heat from the liquid; a manifold extending above a stator of the electric motor, the manifold receiving the liquid under pressure and having a first opening that directs a first liquid jet onto the stator; and a first tray above first end turns of the stator, the manifold having a second opening that directs a second liquid jet onto the first tray, the first tray having a third opening that performs gravity-fed liquid distribution onto the first end turns.

Inventors:

- Palo Alto CA, US
William Randall Fong - Hayward CA, US

Assignee:

Tesla Motors, Inc. - Palo Alto CA

International Classification:

H02K 17/16

US Classification:

310211

Abstract:

A rotor assembly and a method for fabricating the same are provided in which a pair of end caps, positioned at either end of the stack of laminated discs, are fusion welded to the rotor bars using an electron beam welder, thereby yielding improved electrical and mechanical characteristics in a low weight assembly.
