摘要： A power transmitting apparatus on a four-wheel-drive motor vehicle can distribute and transmit drive power from a power unit to front and rear drive road wheels such that the rotational speeds of the front and rear drive road wheels can differ from each other. The power transmitting apparatus includes a casing rotatable by the drive power from the power unit, an output shaft disposed in the casing, first and second planetary gear mechanisms disposed between the casing and the output shaft, the first and second planetary gear mechanisms comprising first and second ring gears fixed to an inner periphery of the casing, first and second sun gears aligned with the first and second ring gears, respectively, first and second planet gears meshing with the first ring and sun gears and the second ring and sun gears, respectively, and rotatable about their own axes and the ring gears, and a planet carrier coupled to the output shaft, the first and second planet gears being rotatably supported on the planet carrier, the first and second planetary gear mechanisms having different speed-changing ratios, one of the speed-changing ratios being selected such that the rear drive road wheels rotate faster than the front drive road wheels, first and second clutches coupled respectively to the first and second sun gears, respectively, for selectively holding the first and second sun gears nonrotatable thereby to enable the first and second planetary gear mechanisms to transmit the drive power, and a pair of variable-torque-transmitting clutches coupled to respective ends of the output shaft.

摘要： A dog clutch mechanism for use as a clutch for switching drive power in a four-wheel-drive vehicle has a case, first and second rotatable shafts rotatably supported coaxially in the case for transmitting a relative torque between front and rear wheels of the vehicle, and a dog clutch comprising a dog piece having first dog teeth and fixedly mounted on the first rotatably shaft and a hub having second dog teeth capable of axially meshing with the first dog teeth and axially slidably mounted on the second rotatable shaft. The dog clutch is selectively engageable for transmitting the relative torque between the first and second rotatable shafts. The first and second dog teeth having respective meshing tapered surfaces for producing thrust forces acting on the hub and tending to move the hub in a direction away from the dog piece when the vehicle is braked while a relative forward torque is being transmitted between the first and second rotatable shafts through the dog clutch.

摘要： A sensor mounting mechanism for a clutch case is provided, which can not only prevent temperature rise of a sensor but also simplify mounting of the sensor on the clutch case. The sensor mounting mechanism is for a clutch case which houses a clutch and a detection object (a pulse gear) rotating with the clutch in unison. A sensor for detecting a rotation of the detection object is inserted through a hole made on the clutch case with a thermal insulator (spacer) and a detector of the sensor is oriented opposite to the detection object.
