The present invention relates to a parking system module, and more specifically, to a parking system module capable of maintaining a parking release state within a mission by using an electric motor when there is a fault in a hydraulic pressure operation. The parking system module comprises a cam piston, a spring, a sprag, and an electric motor. The cam piston is stroked in a predetermined direction by hydraulic pressure force when hydraulic pressure is applied to a parking body in releasing parking. The spring has one side fixed to a spring stopper and is shrunk as the camp piston is stroked to have load. The sprag is rotated to be placed on a parking release position when the cam piston is stroked from the parking position to the release position. The electric motor is rotated in a predetermined direction to allow a rotator to be locked into a hook part of the cam piston. According to the present invention, the number of components can be minimized, and the components can be modularized. |
