Filed:

Aug 5, 1996

Appl. No.:

8/692165

Inventors:

Bruce Edward Crum - Pittsboro IN
Michael Rust Toole - Indianapolis IN
Thomas Lynn Bishop - Indianapolis IN
Rayman Eton Bazilio - Indianapolis IN

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B60T 106
B60K 4126

US Classification:

192 4A

Abstract:

Power transmissions of the automatic shifting type have a park gear secured with the transmission output shaft such that the operator can select the park position to maintain the vehicle immobile. A park pawl is pivotally mounted within the transmission housing to selectively engage the park gear. Selective engagement and disengagement of the park gear by the park pawl is controlled by the vehicle operator through manipulation of the linearly movable actuator which is connected to an operator controlled detent plate.

F16H 1/16
F16D 23/12
F16D 11/14

Abstract:

A vehicle drivetrain for a vehicle including a transmission configured to move the vehicle with a surface engaging traction member and a final drive assembly configured to drive the surface engaging traction member. The final drive assembly includes a drive assembly coupler. A transmission coupler is operatively connected to the transmission and disposed between the transmission and the drive assembly coupler. The transmission coupler includes a first position engaged with the drive assembly coupler and a second position disengaged from the drive assembly coupler. An actuator is operatively connected to the transmission coupler and is configured to move the transmission coupler between the first position and the second position. The actuator, in one embodiment, includes a worm drive having a worm gear configured to move the transmission coupler along a longitudinal direction of the transmission. The worm gear rotates about an axis inclined with the longitudinal direction.
