摘要： A torque transmission coupling includes a rotating shaft and a drive pinion shaft for carrying out input and output transmission of a torque. A torque control part is arranged between the rotating shaft and the drive pinion shaft for controlling torque transmission between the rotating shaft and the drive pinion shaft on the basis of a frictional engagement caused by an electromagnetic force of an electromagnet. At least a portion of the torque control part is arranged in an outer periphery of a taper roller bearing rotatably supporting the drive pinion shaft, thereby allowing a shortening of an entire length of the torque transmission coupling.

摘要： A differential apparatus for a part-time four-wheel drive vehicle is provided. The differential apparatus includes an outer differential casing, an inner differential casing, a clutch member adjacent to the inner differential casing, a pair of dog clutches, a differential gear system arranged in the inner differential casing and an actuator body for actuating the clutch member. One of the dog clutches is connected with the inner differential casing, while the other of the dog clutches is formed on the clutch member. When the vehicle is traveling under two-wheel drive, the inner differential casing and the differential gear system are raced, while the outer differential casing and the clutch member do not race. Accordingly, it is possible to reduce the racing loss of these members and the noise caused by the racing loss.

摘要： A coupling for a vehicle includes a pilot clutch 15, a main clutch 13, a pressing system 21 and a coupling mechanism 17. The pilot clutch 15 generates a pilot torque and is operated by operating means 19. The main clutch 13 connects torque members 11 and 9 and transmits transmitted torque. The coupling mechanism 17 operated by the pilot torque converts the pilot torque into a pressing force for coupling the main clutch 13 via the pressing system 21 by use of a cam thrust force thereof. The main clutch 13 is disposed outside the pilot clutch 15 in a radial direction, and respective members of the pressing system 21 are mutually positioned and designed to move unitarily in a pressing direction, thus sliding portions caused by the main clutch 13 is connecting and disconnecting are limited to being on a side of the main clutch 13.
