A differential used for distributing input torque, is provided with: a casing to receive the input torque; a differential gear set supported by the casing for differentially distribute the input torque to first and second side gears; a clutch interposed between the casing and the first side gear to limit differential motion between the first side gear and the second side gear; an actuator to exert a pressure force on the clutch to control the differential motion; and an electronic control unit configured to calculate a locking rate from a selected differential torque ratio, calculate a requesting torque from a product as a result of multiplying the input torque by the locking rate, and control an electric power to be input to the actuator on the basis of the requesting torque.

Variable characteristic limited-slip differential

A power transmission device according to an aspect of the present disclosure includes a first drive unit having a first drive source, a first transmission connected to the first drive source and the driving force to be transmitted, a second drive source, and a second transmission connected to the second drive source and the driving force to be transmitted, and includes a second drive unit arranged in parallel with the first drive unit, and a frictional differential limiting element disposed between the first transmission and the second transmission and limiting a differential between the rotational drive of the first transmission and the rotational drive of the second transmission.

Power transmission device

A front differential for a four wheel drive vehicle, includes: a switching mechanism that switches the vehicle between rear-wheel drive and front- and rear-wheel drive by selectively interrupting or allowing the transmission of power between one of a pair of side gears and one of a pair of front wheels; and an urging mechanism that urges at least one of the pair of side gears in a drive shaft axial direction toward at least one of the front wheels.

Front differential for a vehicle

A differential gear device includes a case in which a housing portion is formed, and which rotates around a rotation center line; a first protruding portion that is located at a position away from the rotation center line, and protrudes from an inner surface of the case toward the rotation center line, wherein the first protruding portion tapers in a direction from the inner surface of the case toward the rotation center line; a first gear that is provided around the first protruding portion, and that is rotatable; a second gear that engages with the first gear, and that is connected with a first output shaft; and a third gear that engages with the first gear, and that is connected with a second output shaft.
