虽然对内燃机车液力传动不断进行改进,然而其效率仍较电力传动低2—3%。机车在运营费用中,燃料消费占50%,因此,提高内燃机车传动装置的经济性意义就十分重大。达到这个目的的方法之一是降低变扭器循环圆内壁与液流间的摩擦损失。大家知道,在液力变扭器模型中,其通道截面的主要工作状况取决于阻力系数与壁体的 Although the continuous improvement of the hydraulic transmission for diesel locomotives, its efficiency is still 2-3% lower than that of electric power transmission. Locomotives in the operating costs, fuel consumption accounted for 50%, therefore, to improve the economic significance of diesel locomotive gear is very significant. One way to accomplish this is to reduce the friction loss between the inner wall of the converter torus and the flow. As we all know, in the torque converter model, the main working condition of the channel cross section depends on the resistance coefficient and the wall
