  • Patent number: 10525828
    Abstract: A transfer for a vehicle, the transfer includes an input rotating member, a first output rotating member, a second output rotating member, a high-low switching mechanism, a clutch, a motor, a screw mechanism and a transmitting mechanism. The first output rotating member outputs power to first left and right wheels. The second output rotating member outputs power to second left and right wheels. The high-low switching mechanism changes a rate of rotation from the input rotating member and transmits the rotation to the first output rotating member. The clutch adjusts a transfer torque. The transfer torque is transmitted from the first output rotating member to the second output rotating member. The screw mechanism converts rotational motion of the motor to linear motion. The transmitting mechanism transmits linear motion force of the screw mechanism to both the high-low switching mechanism and the clutch.

  • Patent number: 9937789
    Abstract: In a transfer, a high thrust can be given to a front-wheel driving clutch by a high magnification function of a screw mechanism. Further, a necessary stroke for an operation of a high-low switching mechanism can be obtained by the screw mechanism. Accordingly, with the use of one motor, the screw mechanism, and a transmission mechanism, it is possible to perform a switching operation of the high-low switching mechanism and a torque adjustment of the front-wheel driving clutch by the same system. Hereby, it is possible to perform, with accuracy, the switching operation of the high-low switching mechanism and the torque adjustment of the front-wheel driving clutch, based on a motor rotation angle Am of one motor.

  • Patent number: 9751240
    Abstract: A method for manufacturing a resin vehicle part provided with a panel body having a decorative surface on the front surface and a stepped reinforcing rib, which stands on the back surface of the panel body and the thickness of the base end of which is formed to be thinner than the thickness of the leading end. On the injection molding die thereof, a sliding piece for forming the stepped reinforcing rib is provided so as to be movable. During shrinkage movement of the stepped reinforcing rib in the height direction after molten resin has been filled in the injection molding die, the sliding piece is pressed by the leading end of the stepped reinforcing rib and moves towards the panel body.

  • Patent number: 9211855
    Abstract: When the fuel supply to an internal combustion engine has stopped due to a vehicle starting to decelerate or the like, and the speed of the vehicle is greater than a predetermined speed, then a controller causes a power generator to operate in a first power generating mode. The controller charges a capacitor by using regenerative power that is output from the power generator to supply power from the power generator to the capacitor via a DC-DC converter. When the stopping of the fuel supply to the internal combustion engine is cancelled as a result of the engine revolution speed reaching a predetermined revolution speed (for example, an idling revolution speed) in conjunction with the speed of the vehicle dropping to the predetermined speed, the power generator can be kept in the first power generating mode.
