摘要： An apparatus and method are disclosed for controlling fluid flow in a motor vehicle transmission. At least one friction engagement device is fluidly coupled to a first pump, and a lubrication and cooling sub-system is normally fluidly coupled to a second pump. Illustratively, when a flow rate of the fluid in the first fluid passageway is less than a threshold fluid flow rate, a temperature of the fluid is greater than a temperature threshold and a fluid flow demand is greater than a fluid flow demand threshold, fluid flow from the second pump to the lubrication and cooling sub-system is blocked and fluid supplied by the second pump is instead directed to the at least one friction engagement device such that fluid is supplied by both the first and second pumps only to the at least one friction engagement device.

摘要： A gear change control device is provided in which a feedback control level for making an actual gear ratio between input rotational speed and output rotational speed of a transmission coincide with a target gear ratio is calculated. A control level calculation device calculates the feedback control level based on a deviation of acceleration of change in the actual gear ratio with respect to acceleration of change in the target gear ratio thereby making it possible to enhance the control responsiveness compared with a case in which the feedback control level is calculated based on the deviation of the actual gear ratio with respect to the target gear ratio, and also to detect the occurrence of a deviation of the actual value from the target value at early stage and carry out feedback, thus enabling gear change control to be carried out more linearly than in a conventional manner.

摘要： Provided is a single-cavity toroidal continuously variable transmission capable of suppressing gyro slippage and achieving mitigation of bearing loss and a longer service life.In the single-cavity toroidal continuously variable transmission, a pitch circle diameter (PCD) of the output-side bearing 46 is smaller than that of the input-side bearing 43 and a ball diameter of the output-side bearing 46 is smaller than that of the input-side bearing 43. Therefore, centrifugal force acting on the ball of the output-side bearing on a speed increasing side with a low load can be suppressed. Therefore, gyro slippage can be suppressed and mitigation of bearing loss can be achieved. Furthermore, with a groove R ratio of the output-side bearing 46 smaller than that of the input-side bearing 43, a longer service life can be achieved even when the pitch circle diameter (PCD) and ball diameter of the output-side bearing 46 are smaller than those of the input-side bearing 43.
摘要翻译：提供了一种单腔环形无级变速器，能够抑制陀螺仪打滑，减少轴承损耗和延长使用寿命。在单腔环形无级变速器中，输出侧轴承46的节圆直径（PCD）小于输入侧轴承43的节圆直径（PCD），输出侧轴承46的球直径小于输出侧轴承46的球直径。因此，可以抑制作用在低负荷的增速侧的输出侧轴承的球上的离心力。因此，可以抑制陀螺仪滑移，并且可以实现轴承损失的减轻。此外，即使输出侧轴承46的凹槽R比小于输入侧轴承43的凹槽R比，即使在输出侧轴承的节圆直径（PCD）和滚珠直径 46小于输入侧轴承43的尺寸。
