PARKING OVERRIDE DEVICE FOR A SHIFT-BY-WIRE TRANSMISSION

摘要

A shift-by-wire transmission includes a gear set having a gear, a shiftable member that is selectively engageable with the gear to put the vehicle in PARK, and a first intermediate member that is coupled with the shiftable member. The first intermediate member has an engaged position, with the shiftable member engaged with the gear and a disengaged position, with the shiftable member disengaged from the gear, and is biased toward the engaged position. An actuator is coupled with the first intermediate member. The transmission includes a second intermediate member with a nominal position and an override position. In the nominal position the second intermediate member does not move in response to the first intermediate member moving between the engaged position and disengaged position. Moving the second intermediate member from the nominal position to the override position moves the first intermediate member from the engaged position to the disengaged position.
