摘要： A method and mechanism for selectively transmitting and interrupting power between an input shaft and an output shaft arranged in coaxial relation in which a rotary member is coupled to one of the shafts to provide first and second states therebetween and wherein in the first state the rotary member is free to rotate and rotation is transmitted between the input and output shafts, whereas in the second state the input shaft can rotate relative to the output shaft and transmission of rotation is interrupted. The rotary member and the one shaft are angularly rotated relative to one another between first and second relative positions in the first and second states, and rotation of the rotary member is halted by a disc brake in the second state.

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： To the end of eliminating the problems arising from substantially rigid connection between a front wheel set and a rear wheel set in a four-wheel drive vehicle, there is provided a power transmission system in which a speed-dependent power transmission device is provided between the front wheel set and the rear wheel set so that both the wheel sets are substantially rigidly connected to each other in a low speed range and rotational power is transmitted only from the front wheel set to the rear wheel set in a high speed range. The power transmission device of this kind can be conveniently formed by a pair of one-way clutch elements which are connected between an input member and an output member in a mutually parallel relationship; one of the one-way clutch elements transmitting power from the input member to the output member in both the high and the low speed range while the other one-way clutch element transmits power only from the output member to the input member in the low speed range but does not transmit power in either direction in the high speed range. This speed-dependency can be accomplished by using one-way clutch sprag elements each having a gravitational center offset from its center of rolling motion for wedging between the input member and the output member.

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.
