摘要： PROBLEM TO BE SOLVED: To detect movement and the moving direction even when a wheel is moved just a little from the stopped state.
SOLUTION: A detection plate 2 is fixed on a part of an output shaft 1 of a transmission rotating together with the wheel, concentrically with the output shaft 1. A detection part of a detection sensor 4 is faced to a plurality of ridged and grooved parts 3, 3 formed at equal intervals on the circumferential edge of the detection plate 2 in the rotational direction. The detection sensor 4 changes its output signal corresponding to a change of the distance between the detection part and the circumferential edge of the detection plate 2. Accordingly, it can be determined whether the wheel is stopped or not by whether the output signal from the detection sensor 4 is changed or not. In addition, the rotation direction of the wheel can be determined by the tendency of the change.

摘要： PROBLEM TO BE SOLVED: To surely disconnect a high-speed clutch even if oil pressure discharge quantity from a pressurizing pump is small immediately before and after starting after switching a manual selector valve 32a to a range R for reversing. SOLUTION: The manual selector valve 32a is provided with an upstream side discharge port 70 communicated with a high-speed clutch oil pressure chamber attached to the high-speed clutch and a downstream side discharge port 71 communicated with an oil reservoir 30. In the condition wherein the manual selector valve 32a is switched to the range R, both the ports 70 and 71 are communicated with each other to discharge the oil pressure inside the high-speed clutch oil chamber to disconnect the high-speed clutch. With this structure, the high-speed clutch is surely disconnected to prevent driving force applying in the travelling direction even in a short time. COPYRIGHT: (C)2005,JPO&NCIPI
摘要翻译：要解决的问题：即使在将手动切换阀32a切换到用于反转的范围R之后，立即将启动前后的加压泵的油压排出量变小，也可以切断高速离合器。解决方案：手动切换阀32a设置有与安装在高速离合器上的高速离合器油压室连通的上游侧排出口70和与油箱30连通的下游侧排出口71。在将手动切换阀32a切换到范围R的状态下，两端口70,71彼此连通，排出高速离合器油室内的油压，使高速离合器断开。利用这种结构，高速离合器可靠地断开，以防止即使在短时间内也在行进方向上施加的驱动力。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To accurately take out the oil pressure difference of first and second oil pressure lead-in port 89, 90 parts communicating with a hydraulic chamber of an actuator, from first and second differential pressure delivery port 93, 94 parts. SOLUTION: This differential pressure take-out valve for a toroidal-type continuously variable transmission comprises an underlap at a part between the first and second differential pressure delivery ports 93, 94 and drain ports 92a, 92b, and an overlap between both differential pressure delivery ports 93, 94 and a source oil pressure lead-in port 88 in a state of a spool 76 existing in a neutral position with respect to the land of the spool 76 and the inner peripheral surface of a cylinder hole 75. Consequently, even if the spool 76 in the state of existing in the neutral position is slightly moved by vibration, this does not cause the rise of oil pressure at the first and second differential pressure delivery port 93, 94 parts.

摘要： PROBLEM TO BE SOLVED: To provide a toroidal continuously variable transmission of a structure of changing the pressure generated by a pressing device 23b according to the magnitude of the passing torque which is capable of preventing shortage of the pressure even when the direction is suddenly fluctuated, and preventing excessive slip at each traction part. SOLUTION: A flow regulating valve 114 is provided in the middle of a supply/discharge passage 50a to supply/discharge pressurized oil to first and second hydraulic pressure chambers 78 and 79 of the pressing device 23b. The flow regulating valve 114 opens both a throttling flow passage 117 and a communication hole 118 to enable feed-in in a short time when feeding pressurized oil in the hydraulic pressure chambers 78 and 79. On the other hand, when the pressurized oil is discharged from the hydraulic pressure chambers 78 and 79, the pressurized oil is discharged only through the throttling flow passage 117. Therefore, reduction of the pressing force is suppressed when the passing torque is suddenly fluctuated. COPYRIGHT: (C)2005,JPO&NCIPI
