引言在静液压传动装置中,首先从油泵中排出一股静压的油,然后由液压马达依排油原理产生一个机械功率。在此,扭矩的传递主要是通过其静压力,而动压力部分则应尽量保持最小。在静液压传动装置中,液压泵是一个恒定不变的液流的流源。这种控制方式在功率传递方面是有利的,因为在速度调整时没有必要的损失产生。相反,在控制问题上通常应用其恒定压力源的原理。节流时仅仅可能通过一个节流过程,这样就带来很大的损耗。 Introduction In a hydrostatic transmission, a static pressure oil is first discharged from the oil pump and then a mechanical power is generated by the hydraulic motor in accordance with the discharge principle. Here, the torque is mainly transmitted through its static pressure, while the dynamic pressure part should be kept as small as possible. In hydrostatic transmissions, a hydraulic pump is a constant source of fluid flow. This type of control is advantageous in terms of power transfer, since no unnecessary losses occur during the speed adjustment. Instead, the principle of its constant pressure source is usually applied on control issues. When throttling it is only possible to go through a throttling process, which leads to a great loss.
