  • Patent number: 8256593
    Abstract: A driving force transmitting devices is able to engage a main clutch with a small amount of hydraulic pressure. The driving force transmitting device includes an input shaft and an output shaft, and a main clutch. The device is formed of a primary clutch that intermittently transmits the driving force transmitted from the input shaft, a hydraulic pump that generates a hydraulic pressure, a piston that presses the primary clutch with the hydraulic pressure by the hydraulic pump, and a cam mechanism that presses the main clutch with a press-contact force which is amplified to be larger than the press-contact force of the piston by utilizing the driving force from the input shaft through the primary clutch, so as to engage the main clutch.

  • Patent number: 6454070
    Abstract: A limiter plug and a drain plug are juxtaposed in a valve block. The limiter plug is provided with a thermo-switch of which operation, when a predetermined temperature is reached, opens a communication passage for drainage by means of a limiter pin. The drain plug is provided with a drain pin for draining a high-pressure oil in conjunction with the drainage action of the limit pin induced by the thermo-switch so that, when the predetermined temperature is reached, it substantially nullifies the torque for switching from 4 wheel-drive to 2 wheel-drive. In the status of no operation of the thermo-switch, the drain pin when a predetermined torque is reached, gradually opens the drain hole while catching a balance, to limit the torque to a predetermined value.
