在内燃机車液力传动装置中,用于液力制动的液力偶合器以及用于主傳动中高速擋的液力偶合器,均要求泵輪具有較高的扭矩系数,以便减小波力偶合器的尺寸。文内提出了用輪叶向前傾斜来提高泵轮扭矩系数的方法。通过理論分析和实物試驗,說明用輪叶向前傾斜来提高泵輪扭矩系数的方法是十分有效的。
In a diesel locomotive hydraulic transmission, the hydraulic coupling used for hydraulic braking and the hydraulic coupling used for the main transmission medium and high speed gears require that the pump impeller has a higher torque coefficient so as to reduce the wave Force coupling size. This paper presents a method of increasing the torque coefficient of the impeller by forwardly inclining the impeller. Through theoretical analysis and practical tests, it is very effective to explain the method of increasing the torque coefficient of the impeller by forwardly inclining the impeller.
