摘要： A torque transmission device is provided wherein a rotary housing is connected to one of front and rear drive shafts which respectively drive front and rear axles of a four-wheel drive vehicle, while a rotary shaft coaxially carried by the rotary housing is connected to the other of the front and rear drive shafts. The housing receives therein a multiple disc clutch device for transmitting rotational power between the housing and the shaft through friction engagement between alternately arranged outer and inner clutch discs which are respectively rotatable bodily with the housing and the shaft. The housing also receives an axially movable piston to press the clutch discs for friction engagement. An end wall of the housing or an end cap secured thereto and a facing end surface of the piston define an axially narrow circular chamber, within which a rotor with a plurality of radially extending blade portions provided with a pair of slanted surfaces is received to be rotated by the shaft. A several space sections into which the chamber is divided by the rotor blade portions are filled with silicon oil of a high viscosity. When the rotational speed difference occurs between the rotor and the housing, a pressure is generated within each of the space sections thanks to the high viscosity of the silicon oil and is directly applied to the piston, whereby rotational power is transmitted from the housing to the rotary shaft and vice versa.

摘要： A driving free distribution transmission for use with a vehicle with fourwheel drive. The vehicle has first and second drive shafts which are connected with the front and rear wheels, respectively. The transmission has a hydraulic clutch, a differential pump, a bias spring, and a selector valve. The clutch has outer and inner plates which are caused to frictionally engage with each other to transmit rotary power between the two drive shafts. The pump produces a hydraulic pressure corresponding to the difference between the rotating speeds of the drive shafts. The oil delivered by the pump is forced into a reservoir through a first passage in which a restrictor is formed. A second passage connects the pump with an oil chamber in the clutch. A third passage connects the oil chamber with the reservoir without via the restrictor. The spring always presses the outer and inner plates towards each other. When the difference between the speeds of the drive shafts is small, the selector valve closes the second passage and opens the third passage. When the difference is large, the valve opens the second passage and closes the third passage.

摘要： A driving torque transmitting device which has a differential case to which driving torque of an engine is transmitted. Within the differential case, a pair of side gears meshed with pinion gears are disposed around right and left axle shafts so as to be axially slidable thereon. Two annular pistons are disposed between the side gears and end walls of the differential case in contact with the side gears so as to be rotatable with and axially slidable on the differential case to form two annular closed actuating chambers with the end walls of the differential case. Within the closed actuating chambers are disposed two blade plates so as to rotate respectively with the two axle shafts whereby the actuating chambers are divided into two spaces. These two spaces are charged with high-viscosity oil. Due to the relative rotation of the two axle shafts and the differential case, high pressure is generated in the closed actuating chambers to push the pistons toward the side gears so that the side gears are tightly engaged with the pinion gears. Accordingly, the two axle shafts start rotating integrally with the differential case.

摘要： A device for detecting driving condition faced by an operator of an automobile. The device includes an automobile speed sensor, first arithmetic means, second arithmetic means and compensating means. The first arithmetic means computes a driving condition index by using automobile speed information. The second arithmetic means computes limit value changing according to the increment in the automobile speed. The compensating means compare the change amount of the driving condition index for a predetermined time period with the limit value and compensate the driving condition index in such a way that the change amount of the driving condition is limited to the limit value when the change amount exceeds the limit value in order to give the operator a natural feel of the road.

摘要： A driving status discrimination device for a motor vehicle is provided with a microcomputer, which stores in a memory a plurality of the latest steering angle signals which are output from a steering angle detector each time the vehicle runs a predetermined distance. The microcomputer processes the steering angle signals stored in the memory to calculate a discrimination value and then, compares the discrimination value with a predetermined reference value, so that the driving state of the vehicle can be judged to be either of a mountain road driving and a town street driving. To calculate the discrimination value, the microcomputer in one embodiment searches said memory for some of the steering angle signals whose values belong to a particular one of classification intervals and calculates the ratio of said searched steering angle signals to all of the steering angle signals stored in the memory. Also to calculate the discrimination value, the microcomputer in another embodiment calculates a mean value of absolute values of the steering angle signals stored in the memory.
