摘要： PURPOSE:To aim at improvement of heat radiation performance of the central portion of a multiple disk clutch by forming a central plate maximum thick and forming the plates positioned parallelly left and right the central plate thiner in order. CONSTITUTION:The separate plate 37 of a multiple disk clutch 40 is arranged in a way that a central plate 37A is formed maximum thick and the thickness of the left plates 37LB-37LD and the right plates 37RB-37RD of the central plate 37 are formed thiner in order as they become more distant. The multiple disk clutch 40 generates heat due to its friction and the heat is transferred and radiated from the separate plate 37 to a cylinder housing 32. Since the central plate 37A has the maximum thickness, heat transfer coefficient is height so that radiation performance can be improved.

摘要： PROBLEM TO BE SOLVED: To provide a driving force transmission control device for automobiles that provides sufficient durability against vehicle vibrations and foreign objects. SOLUTION: In a clutch device 10, an electromagnet 60 is prevented from turning as it is engaged with an engaging protrusion (engaging member) 92 provided in a bearing retaining member 86 of a bearing retaining unit 90 secured to a vehicle body. As a result, vibration from the vehicle body is transmitted via a cushioning member 84 to the engaging protrusion 92 and the electromagnet 60. This substantially reduces mechanical vibration transmitted from the vehicle body to the electromagnet 60 or clutch device 10, allowing a driving force transmission control device for automobiles to provide sufficient durability.

摘要： PROBLEM TO BE SOLVED: To facilitate the circumferential direction positioning work of an electromagnet and a casing by forming an opening part in the casing and arranging a positioning mechanism by being faced toward the opening part. SOLUTION: When a cover 6 and a differential carrier 1 are coupled in an assembling work, these cover 6 and carrier 1 and an electromagnet 35 are relatively moved in the axis A1 direction and the electromagnet 35 is inserted into the cover 6 by being passed through an opening 6A. Because the electromagnet 35, a projecting part 69 and a whirl-stop pin 72 are arranged by being faced toward opening parts 1A, 6A, a worker can confirm the circumferential direction phase of the electromagnet 35 and the cover 6, that is, the whirl-stop pin 72 and a notched part 70 from the outside of the cover 6 and the carrier 1 immediately before a state that the cover 6 and both of the end faces of the carrier 1 are abutted. When the phase is different, the carrier 1 and the cover 6 are stopped, the electromagnet 35 is revolved, and the phases of the whirl-stop pin 72 and the notched part 70 are made to coincide with each other. Therefore, the circumferential direction positioning work of the electromagnet 35 and the cover 6 can be easily and quickly performed.

摘要： PROBLEM TO BE SOLVED: To suppress entering of foreign matter into a gap of an electromagnet of a clutch mechanism and a magnetic body by providing an isolating mechanism forming an electromagnet storing chamber by fluid-tightly isolating space in which the gap is arranged and the surrounding space. SOLUTION: A gap El between the inner periphery of an iron core 36 and the inner cylinder part 28 of a magnetic body and a gap Fl between the outer periphery of the iron core 36 and the outer cylinder part 30 of the magnetic body are set by a single bearing 41. An electromagnet 35 and the gaps El and Fl are arranged in an electromagnet storing chamber Cl by fluid-tightly isolating the electromagnet storing chamber Cl and the surrounding space by a differential carrier 1, a cover 6, a coupling case 7, an oil seal 34, an O ring 33 and a sealed bearing 33. Therefore, entering of foreign matter such as differential oil filled in a differential oil chamber Bl or abrasion powder generated by the engagement of gears each other into the electromagnet storing chamber Cl is suppressed.

摘要： PURPOSE:To contrive elimination of seizure or the like by providing a circulation path in a radial directional location of a rotary member such as an acting piston while cutting off communication of the circulation path and releasing the cutting off when a cutoff member reaches a predetermined temperature. CONSTITUTION:When relative rotation is generated between both the first and second propeller shafts 25, 26, relative rotation is generated between an outer case 11, acting piston 13 and a retainer 15, which are integrally rotatably built in the shaft 25, and an inner shaft 12 and a rotor 14 which are integrally rotatably built in the shaft 26. Accordingly, in a fluid chamber of a pressing force generating means 10a, the acting piston 13 is pressed in the axial direction by forcedly fluidizing viscous fluid in a stay-accumulating chamber R2 at a speed in proportion to the time of relative rotation and by generating pressure distribution in which a pressure in a stay-accumulating chamber R2, successively relatively moving in the peripheral direction, is gradually increased toward the upstream side end of a next vane part 14b from the downstream side end of a vane part 14b being caused by fluidization resistance.

摘要： PURPOSE:To prevent change of the viscous property or a viscous fluid and maintain the torque transmission property of a driving force transmission device by providing a communicating hole opened to the side of the housing chamber of a friction clutch to an annular groove with which a seal member that seals between a working piston and an outer rotary member liquid-tight is engaged. CONSTITUTION:An annular groove 13d is formed on the outer circumference of a working piston 13, and a seal ring 18 in a O-shape of elastic member is fitted there. And, a communicating hole 13f is formed to the working piston 13, with its one end is opened to the bottom part of one side wall 13e that constitutes the annular groove 13d and its another end is opened to a clutch housing chamber R1 communicating these annular groove 13d and clutch housing chamber R1 together. The seal ring 18 is pushed against an outer case 11 and positions in the annular groove 13d in the state of initial assembly, sealing between the outer circumference of the working piston 13 and the inner circumference of the outer case 11 liquid-tight. With these means, clutch oil does not return to the clutch housing chamber without being confined in it, eliminating lowering of the torque transmission property of the driving force transmission device in question.

摘要： PURPOSE:To lower increase rate of transmission torque in the low differential rotation zone as well as to raise the increase rate of the transmission torque in the high differential rotation zone by providing a spring which applies force in the direction that the first working piston is removed from the second working piston. CONSTITUTION:When relative rotation is generated between both propeller shafts 25 and 26, pressure corresponding to the number of differential rotations is generated in fluid chambers of both pressurizing force generating means 10a and 10b to pressurize both working pistons 13 and 16 in the axial direction. The piston 16 directly pressurizes a frictional clutch 10c and frictionally engages each of clutch plates 19a constituting it with clutch disks 19b through oil for clutch. On the other hand, as the piston 13 is pressurized against a compression spring 19d, it does not aid pressurizing force of the piston 16 till it overcomes the applied force of this spring 19d, but when it overcomes the applied force, it aids pressurizing force of the piston 16 corresponding to the number of differential rotations and further increases frictional engaging force between the plates 19a and the disks 19b.
