液压传动系的特点是,容易改变大功率输出旋转运动的方向,可以任意变化旋转速度。所以,近年来已被用在许多小型拖拉机上。日本采用轴向柱塞泵(变量泵)和轴向柱塞液压马达(A公司)。美国20马力以下的小型拖拉机(园林拖拉机)也使用这类泵和马达(B公司)。1司时,也有的用球塞泵(变量泵)和球塞马达(C公司等)。这些都是根据用途,决定其容量、回路和没计传 Hydraulic transmission system is characterized by easy to change the direction of high-power output rotary motion, you can freely change the rotation speed. So, in recent years it has been used on many small tractors. Japan uses axial piston pump (variable displacement pump) and axial piston hydraulic motor (company A). Small pumps (garden tractors) below 20 horsepower in the United States also use these pumps and motors (company B). 1 Division, there are some with the piston pump (variable displacement pump) and the ball-point motor (C company, etc.). These are based on use, to determine its capacity, circuit and did not count pass
