摘要： The transmission includes an orbital gear complex in combination with a variable hydraulic pump and motor. The input to the transmission is increased in speed by the orbital gearing such that, when the pump and motor are not operating, the orbiter is stationary, and the orbital gearing produces an overdrive condition. A gear reduction is accomplished by rotating the web with the web-rotating device, providing a high gear reduction. The pump and motor are preferably long-piston hydraulic machines with infinitely variable swash plates. The hydraulic machines preferably have wobblers stabilized by full gimbals and hold-down plates with elongated holes for the long pistons to eliminate possible impacts between the hold-down plates and the head ends of the long pistons when the swash-plates are at or near their maximum angle of inclination.

摘要： A transmission has only a single, minimal orbiter in which an input gear and an output gear, each being connected to separate input and output shafts, are interconnected through an orbiting cluster gear that meshes with only the input and output gears. The cluster gear is carried by a web that is itself rotated by a hydraulic control motor through a first clutch. When rotation of the web is prevented, rotation of the input gear produces rotation of the output gear at a predetermined reduction of the input drive, this gear reduction being continuously diminished proportional to the speed of rotation of the web in a first direction. When the vehicle reaches highway speeds, the control motor is disconnected and a second clutch is activated to connect a predetermined overdrive that is located between the engine drive and the transmission rather than being conventionally positioned between the transmission and the final output shaft.
摘要翻译： 变速器只有一个最小的轨道器，其中每个连接到分离的输入和输出轴的输入齿轮和输出齿轮通过仅与输入和输出齿轮啮合的轨道式集群齿轮相互连接。 集束齿轮由本身由液压控制电动机通过第一离合器旋转的腹板承载。 当防止卷筒纸的旋转时，输入齿轮的旋转在输入驱动器的预定减小时产生输出齿轮的旋转，该齿轮减速度与纸幅沿第一方向的旋转速度成比例地连续减小。 当车辆达到公路速度时，控制电动机被断开并且第二离合器被启动以连接位于发动机驱动器和变速器之间的预定过载，而不是传统地位于变速器和最终输出轴之间。
