一种称为液力换向的传动装置运用液力变扭器的两种传动性能:高效率时的牵引性能和反向旋转时的制动性能。这种液力换向传动装置从最早的部分模型发展到现代的类型已经有好几年了,并且在调车内燃机车上运用得很成功。费廷格尔的液力元件充排油原理不仅容许选择不同传动比的液力元件,没有磨耗和擦伤,毫无负荷的危险,而且还容许双向旋转——换句话说,容许双向传递功率。一般液力变扭器和机械式换向机构的组合装置所遇到的所有问题,在这种液力换向的传动装置中都避免了。
One type of transmission known as a hydrodynamic commutation uses two transmission characteristics of a torque converter: traction performance at high efficiency and braking performance in reverse rotation. It has been several years since the hydraulic steering gear was developed from the earliest partial models to the modern one and has been used successfully on shunting diesel locomotives. Fittinger’s hydraulic components charge and discharge principle not only allows the choice of different transmission ratio of the hydraulic components, there is no wear and tear, no risk of load, but also allows two-way rotation - in other words, to allow bidirectional transmission power . All of the problems encountered with a combination of a conventional torque converter and a mechanical reversing mechanism are avoided in such hydraulic reversing transmissions.
