在轮胎式工程机械中,有很多都采用了液压技术。有些用的液压元件和液压系统比较复杂,但是有一种机器只用了一个定排量泵、一个定排量液压马达和一个相当简单的操纵廻路。Hough 公司生产的H-25型装载机(图1系该机液压元件布置图),功率为48马力/2200转/分,以一个双作用页片泵与发动机曲轴直接联接,一个单作用定排量页片泵装在驱动轴的外壳上。液压马达的输出轴通过一个常用的限滑差速器驱动主动轮。
Many of the tire construction machinery employ hydraulic technology. Some hydraulic components and hydraulic systems are more complex, but one machine uses only a fixed displacement pump, a fixed displacement hydraulic motor and a relatively simple control circuit. The H-25 loader manufactured by Hough (figure 1 is the layout of the hydraulic components of the machine), with a power of 48 hp/2200 rpm, directly connected to the crankshaft of the engine by a double acting blade pump, a single-acting fixed row The volume pump is mounted on the housing of the drive shaft. The output shaft of the hydraulic motor drives the drive wheel through a common limited-slip differential.
