摘要： PROBLEM TO BE SOLVED: To secure proper transmission torque by constituting a pressure generating means with three stationary blades integrally rotating with a turning shaft, a viscous fluid filled up in plural pressure chambers partitioned off by these blades, and a movable blade being relatively shiftable in the circumferential direction among these three stationary blades. SOLUTION: A space part 20 is recessingly installed in one end of a piston 16 being opposite to a rear housing concentrically with a turning shaft 14. A rotor 21 is engaged of its central part with a peripheral part of this turning shaft 14 by means of a spline. In addition, plural blades being thick-wall slightly smaller than an axial size of the space part 20 are projectingly installed in this rotor 21 at equiangular intervals on the circumference in the radial direction, whereby the space part 20 is partitioned to plural pressure chambers 23 by these blades 22. In addition, each top of these stationary blades 22 is given a small clearance 28 to an inner circumference of the space part 20, and thereby a viscous fluid 27 is made so as to pass through, as being restricted, between both sides in a sense of rotation of the stationary blades 22 in terms of design. With this constitution, the extent of responsiveness in time of the turnabout of differential rotation is improvable.

摘要： PROBLEM TO BE SOLVED: To instantly put a friction clutch in a joined condition by generating pressing force to frictionally engage the friction clutch by a first pressing force generating means and a second pressing force generating means, and controlling this by a control means. SOLUTION: Differential rotation is generated between first and second propeller shafts, and when relative rotation is generated between an outer housing 10a and an inner shaft 10b, pressing force is generated in first and second pressing force generating means 10d and 10e. A cam mechanism 16 is actuated by frictional engaging force of a pilot clutch 15, and a cam-follower 16c presses a first cam member 16a to the main clutch 10c side. A main clutch 10c is strongly pressed from both sides by pressing force generated by the first and the second pressing force generating means 10d and 10e, and is firmly and frictionally joined. An electric current is carried to an electromagnet 18 to constitute a control means 10f, and the second pressing force generating means 10e is put in an effective condition, and when differential rotation is generated between both propeller shafts, the main clutch 10c is instantly put in a joined condition.

摘要： PURPOSE:To perform control of a damping force and production of a difference in a damping force between forward and reverse rotation directions by sensing a relative rotation angle and a speed. CONSTITUTION:A rotary shaft 3 is rotatably supported on a rotary shaft 3 in a cylindrical housing 1 and the interior of the housing 1 is divided into two spaces by means of a partition wall 4 in which holes 5 are formed. A partition wall 10 is located in the one space between the inner wall of the housing 1 and the rotary shaft 3 in a manner to approach the hole 5. Chambers S1 and S2 partitioned by means of a rotor 7, fixed on the rotary shaft 3, and the partition wall 10 and communicated with each other through a throttle passage 11 and having a hole 5 formed in the one chamber are formed in the one space. In the other space, a piston 8 pressed and energized in the direction of the hole 5 of the partition wall 4 through the force of a spring 9 is axially displaceable arranged in an engaged manner, and the chambers S1 and S2 are filled with viscous oil.

摘要： PROBLEM TO BE SOLVED: To improve torque transmission characteristic and durability of a driving force transmission device by providing many fine projecting streaks extending in the circumferential direction in parallel while holding fine spaces on a frictional engaging face. SOLUTION: A friction clutch of this driving force transmission device is a wet multiple disc type, respective inner clutch plates 14a and respective outer clutch plates are alternately positioned, and they are contacted with each other and frictionally engaged. The inner clutch plate 14a is provided with many projecting streaks 14a4 in parallel on the whole surface of the frictional engaging face of a plate main body 14a1 while holding fine spaces. The projecting streaks 14a4 are extended in the circumferential direction and concentrically arranged in parallel with each other. Hereby, in this driving force transmission device, torque transmission characteristic is improved, judder resistance and responsiveness are favorable, drag torque due to viscosity of oil film is reduced, and hence durability is improved.

摘要： PROBLEM TO BE SOLVED: To improve responsiveness of operation by constituting capable of integral rotation of a clutch plate opposed to an armature of a frictional clutch with the armature, and providing an oil film exhaustion promoting means on at least one side of both opposing surfaces. SOLUTION: An armature 15 and an outer clutch plate 14b opposed to this are assembled freely to rotate integratedly in relation to a front housing 11a together with the armature 15, an outer clutch plate 14b opposed to a rear housing 11b is assembled freely to rotate integratedly in relation to the front housing 11a, and the outer clutch plate 14b is rotatably integrated with the rear housing 11b. In numerable oil delivery grooves formed in a curve shape are formed on the whole surfaces of an opposing surface 14b1 of the outer clutch plate 14b and the armature 15, and opposing surface 14b2 of the outer clutch plate 14b and the rear housing 11b. As a result, oil film exhaustion is promoted between the outer clutch plate 14b and the armature 15, and between the outer clutch plate 14b and the rear housing 11b, and it is possible to prevent operation responsiveness of a frictional clutch 14 from degradation.

摘要： PROBLEM TO BE SOLVED: To check the transmission of any vibration in a pilot clutch mechanism to a main clutch mechanism, thereby preventing any possible judder from occurring by interposing a vibro-damping means in an operating force transmitting route between both these main and pilot clutch mechanisms. SOLUTION: A friction engaging force to be produced in a pilot clutch mechanism 10d is transmitted to a main clutch mechanism 10c from a cam mean consisting of a first cam member 16, a cam follower 18 and a second cam member 17 of a transmission mechanism 10e through an elastic ring 19b and a piston 19a. In consequence, any vibration to be produced in the pilot clutch mechanism 10d is damped while being transmitted to the main clutch mechanism by the elastic ring 19b being interposed in a transmitting route of the friction engaging force. Accordingly, the vibration being inevitably produced will not utterly transmitted or almost nothing to the main clutch mechanism 10c, and thus any possible judder is prevented from occurring and/or being sharply controlled.

摘要： PROBLEM TO BE SOLVED: To improve gap accuracy by providing a first bearing setting a gap between a first rotating member and an electromagnet and a second bearing supporting the first rotating member between a fixing member and the first rotating member and arranging both of the bearings at the same location of the axial direction by being radially overlapped. SOLUTION: Gaps E1, F1 are set by a bearing 41 to be a single component mounted between an inner cylinder part 28 and an electromagnet 35. Because the bearing 41 to be a radial bearing is provided with dimensional accuracy by which the radially relative location of a member to be mounted and a supporting member can be exactly set, setting accuracy of the gaps E1, F1 can be improved as much as possible. Components such as the bearing 41, a whirl-stop mechanism and a sealed bearing 16 are arranged at almost the same location of a axis A1 direction by being radially overlapped. Therefore, arrangement space of the axis A1 direction of the components is suppressed as much as possible and a driving force transmission device can be miniaturized in the axis A1 direction.
