摘要： A transfer mechanism distributes drive power from a drive power source of a motor vehicle to left and right front wheels and left and right rear wheels of the vehicle. A rear differential mechanism transfers the drive power to the left and right rear wheels. A clutch is provided between the rear differential mechanism and each of the left and right rear wheels. A control device independently controls an engaged state of each of the clutches. A speed-increasing mechanism sets revolution speeds of an output shaft of the transfer mechanism and of an input shaft of the rear differential mechanism to be the same and sets a speed of the outer circumference of the rear wheel to which the drive power is transferred, via an engaged clutch, to be faster than a speed of the outer circumference of the left and right front wheels.

摘要： A drain plug is disposed in a drain hole through which oil is discharged from a high-pressure chamber formed in a valve block. Within the drain plug there is arranged a drain pin that slidably opens and closes the drain hole. A fixed pin serves to restrict a displacement of the drain pin. A thermo-switch is located within a low-pressure chamber behind the drain pin in such a manner as to be urged by a return spring so that the drain pin is pressed to keep the drain hole closed. When a predetermined temperature is reached, the thermo-switch allows its head pin to extend, with the reaction force as a result of abutment of the head pin against the fixed pin causing the thermo-switch to retreat to release the pressing force exerted on the drain pin. In consequence, the drain pin is displaced by a high pressure toward the direction in which the drain hole is opened, allowing high-pressure oil to be drained into the low pressure side.
摘要翻译：排水塞设置在排水孔中，通过该排水孔从形成在阀块中的高压室排出油。在排水塞内设有可滑动地打开和关闭排水孔的排水销。固定销用于限制排水销的位移。热开关位于排水管后面的低压室内，以便由复位弹簧推动，以便排水管被压紧以保持排水孔闭合。当达到预定温度时，热敏开关允许其头销延伸，由于头销与固定销的邻接而产生反作用力，导致热敏开关退回以释放施加在该固定销上的压力漏极引脚。因此，排水销朝着排水孔打开的方向高压移位，允许将高压油排入低压侧。

摘要： An axially extending extension is formed on a bearing retainer provided adjacent to a valve block of a joint and press-fitted into the interior of a housing. The extension has at its outer peripheral end a bearing by way of which the bearing retainer is rotatably supported by a differential gear case located outside thereof. This allows moment arising from rotational secondary torque received by the housing to be transmitted from the bearing retainer extension via the bearing to the outside differential gear case, thereby preventing the moment from acting on a main shaft which is a centrally located output shaft.

摘要： A plunger is accommodated in each of a plurality of plunger chambers formed axially in a rotor, with the plunger being displaced by rotation of a cam face associated with a housing. A first one way valve for intake is incorporated in the head of each plunger and a second one way valve for discharge is disposed within in a discharge hole leading to the plunger chambers. The intake stroke of the plunger caused by rotation of the cam opens the first one way valve to suck oil from a low pressure chamber into the plunger chamber. The discharge stroke of the plunger opens the second one way valve to allow the discharged oil to flow through the orifice into the low pressure chamber, whereby a torque corresponding to the relative rotational-speed difference is transmitted from the housing side to the rotor side.

摘要： A torque varying mechanism comprises an accommodation hole that has a relief hole formed in its bottom and that receives a check ball therein. The accommodation hole is configured so as to present a relationship in which the area of flow passage between the accommodation hole and the check ball increases linearly as a function of the amount of displacement of the check ball after opening of the relief hole, after which the flow passage area keeps a unvarying value. A hysteresis characteristic is imposed on a switching point where switching is made between a high torque transmission characteristic and a low torque transmission characteristic relative to an increase and a decrease of the vehicle velocity.

摘要： A torque characteristic shifting mechanism is provided in an accommodation hole of a rotary valve. The torque characteristic shifting mechanism changes over the torque characteristics in a multi-step manner with an increase of the vehicle velocity by setting the distances so as to meet the relationships R3≈R2>R1 or R2>R3>R1 where R1, R2 and R3 are the distance from a center of rotation of a weight member accommodated rockably around the center of rotation to a center of the ball blocking the drain hole, the distance from the center of rotation to a center of gravity of the weight member and the distance from the center of rotation to a center of a spring, respectively.

摘要： To achieve a first object of the present invention, a starting time limit vehicle speed which preferentially permits a torque distribution to front and rear wheels at the time of starting of a vehicle is switched in accordance with a degree of a diameter difference. To achieve a second object of the present invention, when the vehicle makes a normal running with different-diameter tires mounted thereon, a front/rear wheel distribution torque caused by a front/rear wheel rotation speed difference owing to the different-diameter tires is limited by switching a torque gain depending on a degree of a diameter difference.
