A hydraulic system (10) for a vehicle is provided. The hydraulic system comprises a shifting mechanism (20) and a pump assembly (30) configured to provide pressurized fluid to said shifting mechanism (20), and an electrical motor (40). The movement of the shifting mechanism (20) controls a valve function which serves to open a connection from the pump assembly (30) to the electrical motor (40).

A differential apparatus includes a differential mechanism, a differential case that accommodates the differential mechanism, and a clutch mechanism that transmits a driving force between the differential case and the differential mechanism. The clutch mechanism includes a slide member movable inside the differential case in an axial direction and an actuator. The slide member has a first meshable portion at one end in the axial direction, is allowed move relative to the differential mechanism in the axial direction, and is prevented from rotating relative to the differential mechanism. The differential case includes a first case member and a second case member that are united to form the differential case. The first case member integrally includes a second meshable portion and a flange portion that the ring gear is fastened to. When the actuator is activated the first meshable portion meshes with the second meshable portion so that the differential case and the slide member are coupled to present a relative rotation between the differential case and the slide member.

The clutch mechanism includes a slide member movable inside the differential case in an axial direction and an actuator for moving the slide member in the axial direction. The actuator is located outside the differential case. The slide member includes a first meshable portion and an engaging portion engaging with a pinion shaft of the differential mechanism. The differential case has a second meshable portion to mesh with the first meshable portion and a wall portion having multiple insertion holes for transmitting a moving force of the actuator to the slide member. The slide member is located between the second meshable portion and the wall portion.

A differential apparatus includes a differential mechanism, a differential case that accommodates the differential mechanism, and a clutch mechanism that transmits a driving force between the differential case and the differential mechanism. The clutch mechanism includes a side member movable inside the differential case in an axial direction and an actuator for moving the slide member to the axial direction. The slide member has a first meshable portion at one end in the axial direction, is allowed to move relative the differential mechanism, and is prevented from rotating relative to the differential mechanism. The differential case has a second meshable portion facing the first meshable portion in the axial direction. When the slide member moves toward the second meshable portion by actuation of the actuator the first meshable portion meshes with the second meshable portion so that the differential case and the slide member are coupled to prevent a relative rotation between the differential case and the slide member.
