Patent ID: 6994650

Claim:
A park brake mechanism for braking a drive line that transmits power to the wheels of a motor vehicle, comprising: an epicyclic gearset driveably connected to the input and the output, adapted to produce alternately a high range of output speed and a low range of output speed; a coupler including a selector moveable alternately between a first position where the gearset produces the high range, and a second position where the gearset produces the low range; a park gear driveably connected to the input; a pawl supported for releasable engagement with the park gear and preventing rotation of the park gear due to such engagement; a gear selector moveable among positions representing operating ranges of a transmission, the positions including a park position; and a connector attached to the gear selector and the pawl, adapted to transmit movement of the gear selector to the pawl, the pawl engaging the park gear and preventing rotation of the park gear in response to movement of the gear selector to the park position.
