摘要： A planetary gear system employs a retarder to provide fluid coupling of power during startup and fluid braking during deceleration. At idle with the output shaft stationary, an input shaft rotates in one direction and the retarder rotates in the opposite traction. When the retarder is activated by adding working fluid, the resultant torque coupled to the output shaft rotates the output shaft in the same direction as the input shaft. The retarder rotor can be mechanically braked to produce a first mechanical gear. Further coupling rotates the input shaft, output shaft and retarder rotor at the same speed in the same direction to form a second mechanical gear. Hydrodynamic braking can be performed in the second mechanical gear by adding working fluid to the retarder. A control system is disclosed which varies the level of working fluid during acceleration to a value which permits the input shaft to rotate at a required value regardless of the acceleration input signal. In addition, acceleration can be controlled proportionally to the output shaft speed. At a predetermined value of output speed, the retarder is automatically drained in order to take advantage of mechanical gearing. During braking, the level of fluid in the retarder is varied to provide a braking torque proportional to the braking signal.
摘要翻译：行星齿轮系统采用减速器来在启动期间提供动力的流体耦合和减速期间的液体制动。在输出轴静止时，输入轴在一个方向上旋转，延迟器以相反的牵引力旋转。当通过加入工作流体来启动延迟器时，结合到输出轴的转矩使输出轴沿与输入轴相同的方向旋转。减速器转子可以被机械地制动以产生第一机械齿轮。进一步的联接使输入轴，输出轴和减速器转子在相同方向上以相同的速度旋转以形成第二机械齿轮。可以在第二机械齿轮中通过向延迟器加入工作流体来进行流体动力学制动。公开了一种控制系统，其将加速期间的工作流体的水平改变为允许输入轴以所需值旋转的值，而与加速度输入信号无关。此外，可以按照输出轴转速成比例地控制加速度。在输出速度的预定值下，为了利用机械传动装置，减速器被自动排水。在制动期间，减速器中的流体水平被改变以提供与制动信号成比例的制动力矩。
