    摘要： A power split transmission includes a hydraulic power branch having two hydraulic machines arranged in a hydraulic circuit, at least one of which comprises an adjustable displacement. The transmission comprises a control device for controlling the transmission ratio, and is configured to actuate at least the one adjusting device at a displacement setting. The displacement setting is adjusted in relation to a displacement setting oriented to a current demand, at least in a drive mode or drive mode section in which the displacement of one of the hydraulic machines reaches a maximum or is reduced from this maximum.

    摘要： A change spur gear of reducer unit design features two paths of force. The first path of force comprises a unit which provides gearing to high speed, a hydrodynamic torque converter and, following it, a multiple shift gear. The second path of force comprises as well a unit which provides gearing to high speed, on the high speed shaft of which there is a hydrodynamic servoclutch arranged. The secondary vane wheel connects through appropriate reducers with the transmission output. In shifting from one gear to another, the servoclutch is filled first, then the respective shift detent is disengaged under no load, the servoclutch is adjusted to the slip corresponding with the next gear thereby enabling a no-load shifting of the detent of the next gear. Upon emptying of the servoclutch, the engine moment is again assumed by the first path of force without any interruption of the traction force.

    摘要翻译： 减速机单元设计改变正齿轮具有两条力的作用。 第一路径包括提供高速传动的单元，液力变矩器以及随后的多档变速齿轮。 第二路力也包括高速轴上提供高速齿轮的单元，其中布置有流体动力伺服马达。 次级叶轮通过适当的减速器与变速箱输出连接。 在从一个齿轮传递到另一个齿轮的同时，首先填充伺服电机，然后相应的换档制动器在无负载下分离，将伺服电机调整到与下一个齿轮相对应的滑动，从而使得下一个齿轮的制动器能够无负载地移动 齿轮。 在排空伺服电机时，发动机力矩再次由第一路径承受，而不会导致牵引力的任何中断。

    摘要： A cost configurable drive system for machines having dual/tandem axle drive systems employs a split hystat power system. The system performance can be easily adjusted by the removal or installation of a planetary gear set and a clutch box. In this way, the system is configurable with components removed or substituted to allow for a less capable but lower cost offering, while allowing for very simple upgrade to a fully capable system.

    摘要： A hydrodynamic 2-speed turbine drive, in particular, a turbine drive for application in under-floor or low-floor drive systems on rail vehicles, with two hydrodynamic components for the formation of two tractive-work circuits for two different speed ranges. A first hydrodynamic component is in the form of a hydrodynamic speed/torque converter and a second hydrodynamic component is in the form of a hydrodynamic clutch. The converter and the clutch are arranged parallel to each other and with no, or very little, offset between drive input shaft and drive output shaft.
