摘要： A transfer for a four-wheel drive vehicle, the four-wheel drive vehicle configured to disconnect a propeller shaft from a power transmission path between an auxiliary drive wheels and a driving power source when the four-wheel drive vehicle travels by two-wheel drive, includes a second output rotating member and an oil pump. The second output rotating member is configured to output a driving power to the propeller shaft. The oil pump is configured to rotationally drive in conjunction with rotation of the second output rotating member via a first one-way clutch. The first one-way clutch is configured such that the oil pump supplies a lubrication oil to a wet clutch when the four-wheel drive vehicle travels forward by the four-wheel drive. The oil pump is configured to stop supplying the lubrication oil to the wet clutch when the four-wheel drive vehicle travels forward by the two-wheel drive.

摘要： A transfer for a four-wheel drive vehicle includes an input shaft, an output shaft, a high-low switching mechanism, an output member, a clutch, a locking sleeve, a screw mechanism, a transmitting mechanism, a drum cam, and a switching mechanism. The switching mechanism is configured to selectively switch between an H4L position and an L4L position in conjunction with rotational motion of the electric motor. The H4L position is a position in which a high-low sleeve provided in the high-low switching mechanism is in a position in which a high-speed gear is established in the high-low switching mechanism. The L4L position is a position in which the high-low sleeve provided in the high-low switching mechanism is in a position in which a low-speed gear is established in the high-low switching mechanism.

摘要： 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.

摘要： In a differential limiting device for a vehicle, when rotary motion of an electric motor is converted by a screw mechanism into linear motion of a nut member in a direction of a first axis C1 of a side gear shaft, and a piston mounted on the nut member is moved in a direction opposite to a direction to depress frictional engagement elements, the piston and a clutch drum are relatively non-rotatably engaged. Therefore, differential rotation of a pair of side gears is mechanically limited. Thus, rotation of one electric motor makes it possible to generate differential limiting torque for limiting differential rotation of the pair of side gears in a rear-wheel differential device.

摘要： A transfer includes: an input shaft; an output shaft; a high-low switching mechanism; an output member whose output destination is different from output destination of the output shaft; a clutch for transmitting a power to the output member; a first transmitting mechanism for transmitting movement of an internally threaded member to the clutch; and a drum cam having a cam groove. The cam groove includes a first inclined section that causes the high-low switching mechanism to be switched between a high-speed gear stage and a low-speed gear stage, and a second inclined section that causes the first transmitting mechanism to be switched between (i) a separated position in which the first transmitting mechanism is separated from the clutch and (ii) a contact position in which the first transmitting mechanism is in contact with the clutch, while the high-speed gear stage is established in the high-low switching mechanism.

摘要： 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.
