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.

摘要： An improvement is provided in a differential gear which includes an input shaft, a differential casing adapted to be rotated by the input shaft, a differential pinion shaft radially extending within the differential casing and a plurality of differential pinion gears rotatably mounted on the differential pinion shaft. A pair of side gears having a rotation axis common to that of the differential casing and meshing with the pinion gears, and a pair of output shafts fixed to the side gears. The improvement comprises a centrifugal weight member slidably mounted on the differential pinion shaft and radially inwardly biased, and a multiple disc clutch provided between the differential casing and the output shafts. The clutch is adapted to be engaged in response to the radially outward movement of the centrifugal weight member.
