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 circuit chamber, within which a rotary with several radially extending blade portions is received to be rotated by the shaft. 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 vane type pump with a variable capacity for power steering devices is provided with a movable ring received and radially movable in a closed cylindrical bore of a pump housing. A spring acts on the movable ring to deflect the axis of the movable ring from the axis of a rotor, which is rotated to move vanes along an internal bore of the movable ring. A sealing pin and a valve element are provided at diametrically opposite sides of the movable ring and define first and second pressure chambers around the movable ring. The first pressure chamber receives pressurized fluid from a part of the internal bore of the movable ring and conducts the pressurized fluid into the second pressure chamber through a throttle, which is defined by the valve element and a part of a circumferential external surface of the movable ring. The throttle generates a pressure difference between the first and second pressure chambers, and the pressure difference acts on the movable ring to move the same against the force of the spring. The pump is further provided with a solenoid operated actuator for adjusting the position of the valve element, and a relief valve.

摘要： A tab (51) of a male terminal (50) is inserted into a main portion (11) of a female terminal (10). The tab (51) contacts a contact portion (16) of a resilient contact piece (15) to connect the female and male terminals (10, 50) electrically. A guiding portion (18) is formed on an inner surface of the main portion (11) for guiding the tab (51) inserted into the main portion (11) to a position where the tab (51) contacts the contact portion (16). The guiding portion (18) extends from a position before a contact position of the tab (51) with the contact portion (16) to the contact position while being inclined with respect to an inserting direction of the tab (51).
