摘要： PROBLEM TO BE SOLVED: To provide a friction gearing improved in the durability of an output transmission system by reducing a load of a universal coupling between an output roller and an output shaft. SOLUTION: The amount of the extension of bearing supports 23, 25 is increased by a prop-up force in the mutually separating direction of rollers in the case of bringing the output roller 32 close to an input roller 31 from the bottom dead center (a) to the top dead center (b) to increase a torque capacity. The increase of the offset amount is thereby reduced to improve the durability of the output transmission system. Since an axis O1 is radially fixed but an axis O2 and its turning center O3 are not radially restricted, the extension of the bearing supports 23, 25 converges at the output roller side, and the output roller turning center O3 can be displaced largely as shown by γ2. Consequently, the variation ε2 of the axis O2 can be reduced to improve the durability of the output transmission system. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：通过减少输出辊和输出轴之间的万向联轴器的负载来提供改善输出传动系统的耐久性的摩擦传动装置。解决方案：在使输出辊32从下死点接近输入辊31的情况下，轴承支撑件23,25的延伸量在辊的相互分离方向上通过支撑力而增加中心（a）到上死点（b）以增加扭矩能力。由此减小偏移量的增加，以提高输出传输系统的耐久性。由于轴线O1径向固定，而是轴线O2及其转动中心O3不受径向限制，因此轴承支撑件23,25的延伸在输出辊侧收敛，输出辊转向中心O3可大大偏移，如图所示由γ2。因此，可以减小轴线O2的变化量ε2，以提高输出传动系统的耐久性。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a drive power distribution device capable of realizing a stable housing assembly state even if a first roller abuts a second roller with inclination.SOLUTION: In a drive power distribution device, a shaft portion of a second roller is freely rotatably supported in an eccentric hollow hole of a crank shaft, the second roller is rotated by rotation of the crank shaft about a stationary-shaft axis, and pressing force of the second roller against a first roller in a radial direction is adjusted, to control drive-power distribution between a main drive wheel and a sub-drive wheel. In the device, a first angle is an angle formed between the axis of the first roller and that of the second roller.

An angle formed by an abutting surface between the second roller and a second side-wall and by an abutting surface between the bearing support and housing is an angle produced by subtracting a predetermined angle from the first angle.

摘要： PROBLEM TO BE SOLVED: To permanently hold a rotating position of an output shaft when a torque diode inserted to an irreversible rotation transmission system is locked on by reduction of input torque to zero.SOLUTION: After completion t1 of control to make a crankshaft rotating angle θ become a target value θs by motor torque Tm, when the motor torque Tm is reduced toward zero, the motor torque Tm is not reduced to zero at once at t1 but is reduced at a predetermined time change gradient ΔTm to finally reach zero.

摘要： PROBLEM TO BE SOLVED: To prevent reduction in traction transmission efficiency, when foreign matter in oil intrudes in a pressing contact part in the radial direction between rollers by rotation of the roller whose most part is soaked in the oil.
SOLUTION: The rollers 31 and 32 rake up the oil (an oil level Lo) in a housing 11 as indicated by arrows B1 and B2, and further make this raked-up oil flow down, and then, make the oil proceed again to the contact starting side of both rollers 31 and 32. The lower roller 32 is soaked at the most part in the oil, and when allowing the oil flowed downward as indicated by the arrow B2 by being accompanied by its outer periphery, to proceed to the contact starting side of both rollers 31 and 32 thereafter, transmission efficiency is reduced by making the foreign matter in the oil proceed in large quantities to a mutual pressing contact part in the radial direction of the rollers 31 and 32. Then, a foreign matter catcher 51 is arranged in the lowest part of an oil flowing-down passage, and the foreign matter in the oil is captured and stored so that the foreign matter does not proceed to the mutual pressing contact part in the radial direction between the rollers.
