本文介绍了一种由高速开关系统控制的新型泵/马达变量机构。该变量机构是在传统的泵/马达变量机构的基础上,加以简单的高速开关阀而构成。它具有机构简单、变量准确、能够过零点操作以及响应速度快的特点,适用于运输车辆及工程机械等场合。
This article describes a new pump / motor variable mechanism controlled by a high-speed switching system. The variable mechanism is based on the traditional pump / motor variable mechanism, which is composed of a simple high-speed on-off valve. It has the advantages of simple mechanism, accurate variables, zero-crossing operation and fast response speed, suitable for transportation vehicles and construction machinery.
