摘要： PROBLEM TO BE SOLVED: To achieve size reduction of a power transmitting device while allowing the power transmitting device to sufficiently exert a function as a continuously variable transmission (CVT). SOLUTION: A power transmitting device is configured to eliminate a cancel chamber in a secondary cylinder of a CVT. A hydraulic circuit is configured such that line pressure PL is made to directly act on the secondary cylinder and the line pressure PL is made to flow out from or into a primary cylinder via a control valve. When the vehicle speed V is less than a prescribed vehicle speed Vref, an operation line A for achieving excellent fuel consumption is used to set a lower-limit rpm Nmin. When the vehicle speed V is equal to or more than the prescribed vehicle speed Vref, the lower-limit rpm is set from torque on an output shaft on the basis of required secondary pressure Pss. The lower-limit rpm Nmin of an input shaft is set by using an operation line B, further shifted to the high-rpm side than the operation line A, so as to set the gear ratio that can be achieved from the line pressure PL. The gear ratio (the input rpm) is changed within the range of the lower-limit rpm Nmin. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：为了实现功率发送装置的尺寸减小，同时允许动力传递装置充分发挥作为无级变速器（CVT）的功能。解决方案：电力传输装置被配置为消除CVT的二次汽缸中的取消室。液压回路被构造成使得管路压力PL直接作用在副缸上，并且使管路压力PL经由控制阀从主缸流出或流入主缸。当车速V小于规定车速Vref时，使用用于实现优异的燃料消耗的操作线A来设定下限转速Nmin。当车速V等于或大于规定车速Vref时，基于所需的二次压力Pss，在输出轴上的转矩设定下限转速。输入轴的下限转速Nmin通过使用操作线B进行设定，进一步向操作线A的高转速侧移动，从而设定从行压PL可以实现的变速比。变速比（输入转速）在下限转速Nmin的范围内变化。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To surely carry out sufficient lubrication to an engagement element and to reduce machining man-hours. SOLUTION: A ring type side plate part 4a in a brake hub 4 is connected to the left end of an outer race 3. In the position, with which the left end of the outer race 3 is brought in to contact, in the ring type side plate 4a, a recess part 4c connecting the inner circumference side to the outer circumference side of the outer race 3 is formed. Therefore, in a rotary shaft 1 during its rotation, lubrication oil fed to the axial directional lubrication oil passage hole 1a in the rotary shaft 1 is let flow via a diameter directional lubrication oil passage hole 1b and a lubrication oil passage hole 2a by means of centrifugal oil pressure toward the inner circumference side of the outer race 3, and then, passes the recess part 4c and flows along the ring type side plate part 4a so as to be let flow toward friction plates 5, 7 via a lubrication oil passage hole 4e in a cylindrical part 4b in the brake hub 4. As the recess part 4c is formed in the ring type side plate part 4a, a lubrication passage area can be increased while welding is facilitated, and as a result, machining man-hours can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide the resistance against pitching, wear, breakage, and fatigue by applying gas soft nitriding treatment on steel containing a specific weight ratio of C, Si, Mn, P, S, Cr, and Mo and providing a tooth face with specific compound layer and diffusion layer. SOLUTION: The steel which contains 0.18 to 0.23 weight % of C, 0.15 to 0.35 weight % of Si, 0.60 to 0.85 weight %, of Mn, 0.03 weight % or less of P, 0.03 weight % or less of S, 0.90 to 1.20 weight % of Cr, and 0.15 to 0.30 weight %, of Mo and is composed of the remaining compounds such as Fe and impurities is heat treated, and then a raw material of gear shape is treated by a gas soft nitriding method. The mixed gas composed of Co2 and NH3 containing nitrogen gas is used, gas temperature is 530 to 565 deg.C, and one step treatment is done for two hours. Consequently, a compound layer having a thickness of 2 to 12 μm and a diffusion layer having a hardness of Hv 50 or more which is higher than that of the steel itself and a thickness of 200 μm or more are formed on a tooth face. As a result, it is possible to maintain sufficient resistance against wear and the resistance against breakage and fatigue without affecting gear noise greatly even if a porous layer is peeled off.

摘要： PROBLEM TO BE SOLVED: To quickly converge vibration and improve sound eliminating effect by pressure welding or sticking a damping member on the inside or outside of a drum-like member within a transmission. SOLUTION: The rotating vibration is generated in the engaging surface between a frictional material 4 on a brake hub 3 side connected to a carrier as rotating element and a separator plate 2 on a transmission case 1 side by the play between the claw part and groove part of the spline engagement part of the separator plate 2 by a static slip. This rotating vibration is transmitted to a piston 6 for pressing the separator plate 2. Therefore, an annular elastomer 81 is integrated near the end surface of the major diameter part 61, which forms the maximum amplitude part in vibration, on the inside of the piston 6 as the drum-like member in the state where an initial stress is loaded between the piston 6 and a rigid ring 82. Thus, the annular elastomer 81 is deformed according to the radial expanding and contracting deformation of the major diameter part 61 to change vibration to thermal energy, whereby vibration energy can be damped.

摘要： PROBLEM TO BE SOLVED: To prevent excessive stress from acting on a roller bearing due to partial concentration of the excessive stress to the roller bearing. SOLUTION: Each bolt hole is formed in each region which is deviated from the axial-center surface α passing through the axial center of a primary shaft 22 and that of a secondary shaft 32 in a rear case 11c storing a belt type continuously variable transmission. Each stopper plate 27, 37 is fastened and fixed by each bolt 28, 38 inserted into each bolt hole so as to press each outer race of a bearing supporting each shaft. Therefore, it prevents a region near each bolt-fastening position, where a constraint force acting from each stopper plate 27, 37 on each outer race of the bearing becomes larger, and a region, where a tensile force of a belt or a force generated by a centrifugal force acts along the axial-center surface α, from being overlapped with each other, thereby allowing minute elastic deformation or minute movement within the mounting tolerance range of each outer race even when the bearing receives an excessive force. As a result, it is possible to prevent an excessive stress from acting on the bearing due to partial concentration of the excessive stress to the bearing. COPYRIGHT: (C)2010,JPO&INPIT
