Filed:

Dec 7, 2016

Appl. No.:

15/371376

Inventors:

- Dearborn MI, US
Todd Curtis SPAULDING - Ann Arbor MI, US
Craig Matthew RENNEKER - Northville MI, US
Bryant L. POYNTER - Redford MI, US
Susan WYATT - Milford MI, US

International Classification:

F16H 63/34

Abstract:

An override mechanism for a shift-by-wire transmission includes a housing having a first pin aperture and a shaft extending into the housing. The override mechanism further includes a reel plate having a second pin aperture. The reel plate is rotatably fixed to the shaft and rotatable within the housing. The override mechanism further includes a spring biasing the reel plate to a first angular position, and a pull-pin removably disposable within the first and second pin apertures to retain the reel plate in a second angular position.

Abstract:

A pawl return spring includes a surface contacting portion adapted to contact a transmission housing. The surface contacting portion includes a first connection region and a second connection region opposite the first connection region. The pawl return spring includes an active coil region connected to the first connection region and disposed about a central longitudinal axis to provide torsional effort to the system. The pawl return spring also includes an inactive coil region connected to the second connection region and disposed about the central longitudinal axis that does not provide torsional effort to the system.

International Classification:

F16F 1/12
F16H 63/34
B60T 7/10

Abstract:

In a default-to-park system for a transmission, a lever member has a cylindrical hub configured to rotate about a spindle. The lever member has a transverse plate including a lever arm connected to a park release actuator and to a link to a park pawl of the transmission. Under normal operation, a transmission controller shifts the actuator to turn the lever arm and release the park pawl so the transmission can rotate. In an absence of a signal from the controller to the actuator, a bias spring restores the lever arm so that the transmission is locked. The bias spring comprises torsion coils disposed over the hub, a fixed end, and a drive end. The drive end has a heel segment bearing against a transverse surface of the transverse plate facing the torsion coils and a loading hook wrapped around an edge of the transverse plate.
