Abstract
A park lock mechanism for a motor vehicle includes a park lock pawl for selectively forming a form-locking connection to a lock region, the park lock mechanism having a locking mode, in which the park lock pawl is moved into a locking position, and a driving mode, in which the park lock pawl is moved into a driving position. The park lock pawl is pivotable about a pawl axis from the locking position into the driving position. A locking pawl spring device preloads the park lock pawl into the driving position. A locking pawl actuation device has a locking pawl actuator with a locking pawl actuator shaft and has a locking pawl cone, the locking pawl cone being movable along a cone axis by the locking pawl actuator. The cone axis is parallel to the pawl axis. The locking pawl cone is movable along the cone axis between a cone driving position and a cone locking position. The parking lock pawl is forced into the locking position against the preload of the locking pawl spring device by the locking pawl cone in the cone locking position. A locking cone lever is provided for moving the locking pawl cone along the cone axis, the locking cone lever being freely rotatable by the locking pawl …
