摘要： A connecting system which includes a pilot clutch brought into an engaged state by an actuator, a cam member operated by an engaging force of the pilot clutch, an urging member driven and moved by the cam member, and a main clutch brought into an engaged state by a movement of the urging member. The cam member includes a first cam ring restrained by the pilot clutch, a second cam ring provided on the urging member, and rolling members interposed the first and second cam rings for converting the relative rotation of the cam rings into a thrust. The system further includes a biasing member for biasing the urging member and the first cam ring in a direction of abutment against each other in order to generate a frictional force between the urging member and the first cam ring. Thus, it is possible to prevent the engaging force of the main clutch from being influenced by a drag torque produced in the pilot clutch.
摘要翻译：一种连接系统，其包括通过致动器进入接合状态的先导离合器，由先导离合器的接合力操作的凸轮部件，被凸轮部件驱动和移动的推动部件和成为接合状态的主离合器通过推动构件的移动。凸轮构件包括由先导离合器限制的第一凸轮环，设置在推动构件上的第二凸轮环，以及插入第一和第二凸轮环的滚动构件，用于将凸轮环的相对旋转转换成推力。该系统还包括偏置构件，用于沿着彼此抵靠的方向偏置推动构件和第一凸轮环，以便在推动构件和第一凸轮环之间产生摩擦力。因此，可以防止主离合器的接合力受到先导离合器中产生的牵引力矩的影响。

摘要： A torque transmitting device for transmitting torque by utilizing the viscosity of a fluid includes a casing having a cylindrical barrel having closed opposite ends, shafts rotatably supported in the casing in concentric relation to the cylindrical barrel, a fluid chamber defined by an inner peripheral surface and outer peripheral surfaces of the shafts, a plurality of annular outer plates disposed in the fluid chamber and rotatable with the casing, a plurality of annular inner plates disposed in the fluid chamber alternately with the outer plates and rotatable with the shafts, and a fluid filled in the fluid chamber. Torque can be transmitted between the casing and the shafts through the viscosity of the fluid present between the outer plates and the inner plates. Flow passages are defined in the fluid chamber and extending axially of the shafts for allowing the fluid to flow in the fluid chamber axially of the shafts.

摘要： In a multi-axle drive vehicle having a first axle which is directly coupled to a power source, and a second axle which is coupled to the power source by way of a coupling such as a viscous coupling which is adapted to transmit torque as a mathematical function of a difference in rotational speed between its input end and output end, to the end of eliminating the problems arising from transmission of braking force between the wheels of difference axles, the vehicle is further provided with a clutch for selectively interrupting transmission of power from the power source to the second axle, a brake sensor for detecting activation of a brake system of the vehicle, and a control unit for activating the clutch when the brake sensor has detected activation of the brake system. The conditions for activating the clutch may further include that the vehicle is running at a high speed which may be detected either directly or from a shift position of the power transmission system of the vehicle.

摘要： A power transmission system suitable for use in a four-wheel drive motorcar. A torque generated from a power source is directly transmitted to a first axle, and it is transmitted to a second axle via a torque transmission device making use of viscosity of fluid. Between the power source and the second axle is provided torque limiter means for limiting a torque transmitted to the second axle to smaller than a preset value. Even if the torque transmission device should take a locked condition, an excessively large torque would not be exerted upon the respective parts in the power transmission system, and hence a torque transmission system can be made light in weight.
