Abstract
A parking lock unit for a transmission assembly of a motor vehicle includes a parking ratchet wheel defining a longitudinal axis and a first spring arrangement. A second spring arrangement is arranged radially outwards of the first spring arrangement with respect to a longitudinal axis. A supporting sleeve is arranged coaxially to the parking ratchet wheel and is supported in a circumferential direction by the transmission assembly. The supporting sleeve has at least one opening. At least one locking element is arranged between the first and second spring arrangements and is radially movable in the at least one opening with respect to the longitudinal axis. The locking element is spring loaded by at least one of the first and second spring arrangements. The at least one locking element is movable radially inwards into a locked position and radially outwards into a release position by rotation of an actuating ring about the longitudinal axis.
