Abstract: In a hydraulic system with a dog clutch (23-25), a hydraulically operated dog clutch actuator is arranged to alternatively bring the dog clutch into a connect mode or a disconnect mode. The clutch actuator has a piston (27) reciprocally movable under hydraulic pressure between two end positions, corresponding to the two clutch modes. Pressurized hydraulic oil is supplied to the clutch actuator by a hydraulic power system comprising a pump (4) driven by an electric motor (3). Means are provided in the clutch actuator to decrease the hydraulic pressure acting on the piston (27) at the approaching by the piston of either of its end positions, so that a hydraulic signal is transmitted back to the hydraulic power system.

Abstract: In a default-to-park system for a transmission, a lever member has a cylindrical hub configured to rotate about a spindle. The lever member has a transverse plate including a lever arm connected to a park release actuator and to a link to a park pawl of the transmission. Under normal operation, a transmission controller shifts the actuator to turn the lever arm and release the park pawl so the transmission can rotate. In an absence of a signal from the controller to the actuator, a bias spring restores the lever arm so that the transmission is locked. The bias spring comprises torsion coils disposed over the hub, a fixed end, and a drive end. The drive end has a heel segment bearing against a transverse surface of the transverse plate facing the torsion coils and a loading hook wrapped around an edge of the transverse plate.
