  • Patent number: 8863618
    Abstract: A driving force transmission device for a hybrid vehicle is provided with a motor which drives a rotation shaft, and a connection/disconnection switching device which switches between connection and disconnection of driving force for driving wheels, the driving force being transmitted from an engine. The driving force transmission device is also provided with the auxiliary device driving mechanism, which includes one or more auxiliary device driving shafts for transmitting driving force to the in-vehicle accessory devices, one or more rotation transmission sections which transmit at least either engine's driving force or motor's driving force to one or more accessory device driving shafts via the rotation shaft, and a plurality of one-way clutches provided between the one or more rotation transmission sections and the one or more accessory device driving shafts.

  • Patent number: 7882758
    Abstract: The driving force can be transmitted at the time of both acceleration and deceleration in an engaged state where a first engagement face of a strut is forced to protrude inside a cutaway of a gear. The driving force is transmitted at the time of acceleration and the transmission of the driving force can be cut off at the time of deceleration in a one-way state where the first engagement face of the strut and the cutaway of the gear are made either to engage with or to disengage from each other in accordance with the rotational direction of the gear relative to the rotational shaft. The transmission of the driving force can be cut off at the time of both acceleration and deceleration in a disengaged state where the first engagement face of the strut is forced to withdraw from the cutaway of the gear. In addition, the decreasing of the transmission efficiency caused by friction between the strut and the gear can be prevented.

  • Publication number: 20090078071
    Abstract: Provided is a transmission in which gears of a first-speed to a seventh-speed shift stages are relatively rotatably supported on an outer circumference of a rotational shaft with clutch mechanisms. A desired shift stage is achieved by selectively engaging or disengaging the clutch mechanisms by moving, in an axial direction, the slide cam disposed inside the rotational shaft. While the slide cam is formed into a cylindrical shape, a cylinder, as an actuator, is disposed in a space inside the cylindrical slide cam. Oil chambers are formed inside the cylinder respectively to sandwich a piston therebetween. Oil pressure is supplied to the oil chambers to move the slide cam in the axial direction. The provided transmission with such a configuration has a smaller size than a transmission with the actuator disposed outside the slide cam.
