Abstract: A mechanical oil pump, an electric oil pump, and a strainer are disposed inside a transmission case. As a suction oil passage that returns an excess hydraulic pressure in a hydraulic control device to the mechanical oil pump, a common oil passage extending from the hydraulic control device, a branch point, a first oil passage extending from the branch point to the mechanical oil pump, and a second oil passage extending from the branch point to the electric oil pump are formed in the transmission case. A meeting point where an inlet oil passage for suctioning oil via the strainer and the first oil passage of the suction oil passage meet is formed inside a pump body of the mechanical oil pump. Accordingly, the suction oil passage of the mechanical oil pump and an inlet oil passage of the electric oil pump have a portion in common.

Abstract: A hydraulic control device is disposed forward of a case housing a speed change mechanism in an on-vehicle state. A detent lever is fixed to the control shaft, has a first end connected to a parking rod, and includes a detent recess with which a detent mechanism is engaged. A swing lever includes a shaft serving as a swing center, a first extension extending from one end of the shaft, and a second extension extending from the other end of the shaft. The first extension is connected to a second end of the detent lever. The second extension is connected to a manual valve. An axial position of the manual valve changes in accordance with a rotation angle of the control shaft.

Abstract: Power system including differential-mechanism, clutch-mechanism, power-mechanism and dog-clutch disposed between an input rotary member to receive drive-force from a drive power source and output rotary-member to transmit drive-force to drive-wheels, the differential-mechanism including an input rotary element, output rotary element and reaction rotary element; the clutch-mechanism connecting two rotary elements of the input, output and reaction rotary elements of the differential-mechanism, to each other, the power-mechanism having predetermined gear ratio, and dog-clutch selectively placing a power path between the output rotary element and output rotary-member, in power transmitting state and power cutoff state; transmitting drive-force to drive-wheels while the clutch-mechanisms and dog-clutch are placed in engaged states. The dog-clutch engagement retainer mechanism holds the dog-clutch in engaged state while the power system turns in parking-lock-position inhibiting output rotary-member motion, and switching the dog-clutch from engaged to released when the power system switches to non-parking-lock position permitting the output rotary-member motion.
Abstract translation: 电力系统包括差分机构，离合器机构，动力机构和爪形离合器，其设置在输入旋转构件之间以接收来自驱动电源的驱动力和输出旋转构件以将驱动力传递到驱动轮， 差速机构包括输入旋转元件，输出旋转元件和反作用旋转元件; 所述离合器机构将所述差速机构的输入，输出和反作用旋转元件的两个旋转元件彼此连接，所述动力机构具有预定的传动比，并且所述离合器选择性地将功率路径放置在所述输出旋转元件 并输出旋转构件，处于动力传递状态和停电状态; 当离合器机构和爪式离合器处于接合状态时，将驱动力传递到驱动轮。 当离合器离合器接合保持机构将卡合离合器保持在接合状态时，电力系统转动驻车锁定位置，抑制输出旋转部件运动，并且当电力系统切换到非离合器时，将离合器从接合状态切换到释放状态 - 锁定位置允许输出旋转构件运动。
