摘要： PROBLEM TO BE SOLVED: To prevent a variation in the torque of an electromagnetic friction clutch frictionally engaging an inner clutch plate with an outer clutch plate by the action of magnetic force.
SOLUTION: Both clutch plates 14a and 14b comprise a plurality of arcuate through-holes formed by holding specified intervals on a same circumference. A lubrication groove 14a4 is formed in the frictionally engaged surface of at least one clutch plate 14a. The lubrication groove 14a4 is positioned at a portion other than a compartment part 14a5 demarcating each arcuate through-hole 14a3 in the frictionally engaged surface and prevents the compartment part 14a5 from being projected from the frictionally engaged surface so as to prevent the compartment parts of both clutch plates 14a and 14b from being interfered with each other when the clutch plates are rotated relative to each other. Thus the variation in torque can be prevented.

摘要： PROBLEM TO BE SOLVED: To inhibit the generation of frictional heat by limiting the force for pressing a main clutch to protect a clutch device, when a temperature in a clutch accommodating chamber rises in a driving force transmitting device. SOLUTION: The drag torque generated in a pilot clutch 20 by the viscosity of the clutch lubricant in the clutch accommodating chamber 6 of the driving force transmitting device 1 is amplified by a cam-type amplifying mechanism 15, the pressure in the clutch accommodating chamber is increased by the thermal expansion of the air, when the main clutch 12 generates the heat by the generation of the sliding friction torque, and the temperatures of the clutch plates 13, 14 and the clutch lubricant rise, whereby an inner shaft 7 is moved backward in the rotation axial direction by the pressure difference between the pressure in the clutch accommodating chamber 6 and the atmospheric pressure. When the inner shaft 7 is moved backward, a contact part 30 is kept into contact with a cam member 17 of the cam-type amplifying mechanism 15 to lower the pressure contact force of the main clutch 12, whereby the frictional heat is reduced, and the temperatures of the clutch plates 13, 14 are lowered.

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 control a damping force by means of a friction force by a method wherein viscous oil with which a chamber between a partition wall and a rotor is filled generates an internal pressure, responding to a relative rotation speed, in the chamber through resistance of a throttle passage, and the internal pressure is exerted on a piston through an opening, the area of which is differed with a rotor rotation direction to press a friction clutch. CONSTITUTION:The interior of a housing 1 is axially divided into two spaces by means of a partition wall 13. In the one space, a friction clutch 4 and a press piston 9 are provided. In the other space on the back side of the piston 9, a partition wall 11 is located and chambers S1 and S2 are formed at the front and in the rear in a rotation direction by means of a rotor 12 rotatably located in a rotary shaft 3 and the partition wall 11. The two chambers are intercommunicated through a throttle passage 20 formed in a gap between the outer periphery of the rotor 12 and the inner periphery of the partition wall 11. Holes 14a and 14b and holes 15a and 15b opened to the chambers S1 and S2 and to the back of the piston 9, respectively, and differed in an opening area with size are formed in the partition wall 13. The chambers S1 and S2 are filled with viscous oil. Thus, a difference in a damping force is produced by means of the different friction forces of a friction clutch.

摘要： PROBLEM TO BE SOLVED: To improve the durability of an electromagnetic coil without necessitating conducting a large amount of current by realizing a predetermined driving force transmission condition by a mechanical means independently from an electromagnetic means and holding or reducing an amount of electric power supplied to the electromagnetic means as it is or reducing it. SOLUTION: When pressing force applied from an electromagnetic pilot clutch mechanism 10d through a first cam mechanism 10e is small, a second cam mechanism 10f is in a non-operation condition. Pressing force generated in the first cam mechanism 10e increases, friction engaging force of a mechanical main clutch mechanism 10c increases, and transmission torque increases gradually due to an increase of friction engaging force of the pilot clutch mechanism 10d. When friction engaging force of the pilot clutch mechanism 10d reaches a predetermined value, the second cam mechanism 10f is operated to press a retainer 13 to a main clutch mechanism 10c side so that they are friction-engaged further firmly and are connected. Consequently, it is unnecessary to conduct a large amount of current to an electromagnetic coil 14d and improve the durability influenced by the generation of heat.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of a torque fluctuation due to the interference of partition sections when a friction clutch is operated by forming multiple circular arc-shaped through holes extending in the peripheral direction at prescribed intervals on the same circumference, and forming a lubrication groove at all portions except for the partition sections of the circular arc-shaped through holes on a friction coupling face. SOLUTION: The circular arc-shaped through holes 14a3 of an outer clutch plate 14a are partitioned by partition sections 14a5 at prescribed intervals on the same circumference. A lubrication groove 14a4 is formed at all portions of the friction coupling face of a plate main body 14a1 except for the partition sections 14a5 of the plate main body 14a1 by press machining on the surface. When the lubrication groove 14a4 is formed, the portions other than the partition sections 14a5 are relatively built up, the partition sections 14a5 difficult to polish are recessed as compared with the other portions, thereby the partition sections 14a5 can be prevented from being protruded from the friction coupling face after the surface of the outer clutch plate 14a is polished.
