摘要： A clutch mechanism includes a first and a second rotating members, a clutch hub, a clutch drum, a plurality of friction engagement elements, a piston, a piston driving device and a sleeve. A clutch hub main body of the clutch hub is connected to the first rotating member and does not rotate relative to the first rotating member. An inner hub of the clutch hub rotates relative to the clutch hub main body. The inner hub engages with an inner peripheral side of the friction engagement elements and does not rotate relative to the friction engagement elements. The sleeve does not rotate relative to the inner hub. The sleeve moves relative to the first rotating member. The sleeve moves in conjunction with the piston to a position where the sleeve engages with the clutch hub main body and does not rotate relative to the clutch hub main body.

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.

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： When temperature of a second power source of a vehicle becomes higher than a threshold value during a first mode in which three rotating elements of a differential gear can make differential movement and when four-wheel drive is needed, switching is performed to a second mode in which the three rotating elements are unified, and when four-wheel drive is not needed even when the temperature of the second power source becomes higher than the threshold value during the first mode, output of the second power source is restricted, while the first mode is maintained.

摘要： In a vehicle drive device, a second power source is connected to a first rotating element of a differential mechanism, and the other output shaft of a first output shaft and a second output shaft is connected to a third rotating element so as to be disconnectable and connectable by a disconnection-connection mechanism. A control device places the disconnection-connection mechanism in a disconnected state. When a second traveling mode in which the third rotating element is fixed to a fixing member through engagement of an engaging element is switched to a first traveling mode in which the disconnection-connection mechanism is placed in a connected state, the control device disengages the engaging element, executes synchronous control in which rotational speeds of the other output shaft and the third rotating element are synchronized by a second power source, and switches the disconnection-connection mechanism from the disconnected state to the connected state.
