Abstract
A multi-pawl park lock includes a gear wheel, an actuation ring, a first pawl, a second pawl, and first and second strut rods. The first pawl includes a first tooth and the second pawl includes a second tooth. The strut rods connect the actuation ring to respective pawls. The actuation ring is arranged to rotate in a first rotational direction to rotate the first pawl about a first pawl axis and engage the first tooth with the gear wheel, and rotate the second pawl about a second pawl axis and engage the second tooth with the gear wheel, preventing rotation of the gear wheel. The actuation ring is also arranged to rotate in a second rotational direction, opposite the first rotational direction, to rotate the first pawl and disengage the first tooth, and rotate the second pawl and disengage the second tooth, permitting rotation of the gear wheel.
