摘要： A torque characteristic shifting mechanism (60,62) is provided in an accommodation hole (39) of a rotary valve (11). The torque characteristic shifting mechanism changes over the torque characteristics in a multi-step manner with an increase of the vehicle velocity by setting the distances so as to meet the relationships R3 ≒ R2 > R1 or
R2 > R3 > R1 where R1, R2 and R3 are the distance from a center of rotation (42,43) of a weight member (40,41) accommodated rockably around the center of rotation to a center of the ball (52,53) blocking the drain hole (48), the distance from the center of rotation to a center of gravity (56) of the weight member and the distance from the center of rotation to a center of a spring (46,47), respectively.

摘要： A differential device (11) of the type including a clutch pack (23), engaged by a ball ramp actuator (21), which is initiated by a viscous coupling (19;101). The output of the device (11) is an output shaft (13) which is hollow and extends through the entire axial extent of the device. The viscous coupling (19;101) includes, in the embodiment of FIG. 1, an annular input coupling member (25) and an annular output coupling member (27), within the input member, to define therebetween a cylindrical viscous shear chamber (29). The output coupling member (27) at least partially surrounds the first ramp plate (41) of the ball ramp actuator (21), and is in driving engagement therewith, for improved packaging. The clutch pack (23) and the actuator (21) are disposed about the output shaft (13) and axially retained between snap rings (55,93), so that all axial separation forces generated within the clutch pack and the actuator are taken up within a single member, such as the output shaft (13), rather than being exerted on the connection of the housing (17) and the end cap (15). In the FIG. 5 embodiment, the viscous coupling (101) is in driven engagement with the inner periphery of the first ramp plate (41), with the viscous coupling being of the type including interleaved plates (107,109).

摘要： A control valve (80) of a hydraulic coupling (32) controls pumping from a casing inlet port (58) by a hydraulic pump (48) through a casing outlet port (78) to control coupling between two rotary members such as by operation of a clutch (68). The control valve (80) includes an elongated valve element (82) of a flat shape mounted within an inclined recess (98) to provide accurate control of its closure when the pumped hydraulic fluid reaches a predetermined pressure corresponding to a predetermined extent of relative rotation between the two drivetrain members. This elongated valve element (82) is made from a bimetallic strip so as to be temperature compensated and the outlet port (78) is provided with a main passage (94) as well as a bleed passage (96, 96') that is cleaned when the valve element is opened.

摘要： A center differential device (17) for use in a four wheel drive system, the device including a viscous coupling (29), a ball ramp actuator (31), and a clutch pack (33). Under normal driving conditions, most of the torque is transmitted to the front drive wheels (11), and the device (17) rotates as a unit. If the front wheels (11) begin to slip, the input shaft (15) and input coupling member (35) rotate faster than the output coupling member (43), thus transmitting torque to the output coupling member (43). This torque is transmitted to the first ramp plate (51) of the ball ramp actuator (31), displacing the actuator from its neutral position (FIG. 3), such that the second ramp plate (52) begins to load the clutch pack (33) and transmit torque from the housing (25) to the output shaft (19), and from there to the rear drive wheels (23). With the present invention, for any given mount of front wheel slip, a predetermined amount of torque may be transmitted automatically to the rear drive wheels (23), the viscous coupling (29) providing a "speed sensitive" input to the ball ramp actuator (31), without the need for any separate controls, sensors, etc.

摘要： A lubrication system for an automatic transmission clutch assembly having a drive and driven rotary member (32, 36) rotatable by a common axis with a clutch element (38, 40) therebetween for connecting and disconnecting the members. The drive member (32) has an internal passageway (62) formed therein for feeding the lubricant to the clutch member. The passageway has a section which is radially spaced from the axis of rotation and has a seat (72) formed therein for cooperating with a rotationally speed sensitive valve (74) oriented in the first passageway. Below a first rotational speed, the lubricant pressure maintains the valve against the seat restricting the flow of lubricant to the clutch element. When the driven member is rotated above the first rotational speed. Centrifugal force biases the valve off the seat, allowing lubricant to be supplied to the clutch element. Preferably, a second lubrication passageway (76) is provided having a seat in an internal valve which selectively supplies a lubricant to the clutch element at a second higher rotational speed. In order to further reduce disengaged clutch drag at idle, a speed sensitive piston retract spring (58) is provided to increase piston travel at low engine speeds while maintaining minimum travel at off idle operation.

摘要： A device for transmitting torque between two rotatable, coaxial shaft members (1, 2) in a stationary housing (4) has a clutch (11, 12) engageable to counteract differential rotational speed between the shaft members. A hydraulic clutch piston (14) is arranged to engage the clutch, and a hydraulic pump arrangement (1', 18 - 21, 11'', 14 - 17), driven by the speed differential between the two shaft members, creates a hydraulic pressure on the clutch piston. The hydraulic pump arrangement includes a supply piston (18) and the clutch piston. Rollers (17, 21) are rotatable with one of the shaft members (2) and engage the other of the shaft members (1) via cams (1', 11''), which are angularly offset in relation to each other, so as to impart to the pistons a reciprocating movement at the differential rotational speed between the shaft members. A hydraulic line system (25, 27, 29, 31) connects a cylinder (23) at the supply piston on one hand with the tank (24) via a check valve (26) and on the other hand - via a line (27) with a check valve (28) - with an outlet line (31) and connects a cylinder (30) at the clutch piston (14) with the outlet line.
