1.范围本国际标准规定了用于将液压动力从农业拖拉机传输到农业机械的液压耦合器的基本接口尺寸和操作要求。它适用于液压管路中使用的耦合器，而不是制动回路中使用的耦合器（ISO 5676中包括了这些耦合器）。这些联轴器需要频繁连接和断开，以便将机械从一台拖拉机转移到另一台拖拉机。

1. ScopeThis International Standard specifies the essential interface dimensions and the operating requirements for hydraulic couplers employed to transmit hydraulic power from agricultural tractors to agricultural machinery. It applies to couplers used in hydraulic lines other than those used for braking circuits (wh ich are covered by ISO 5676). These couplers need to be connected and disconnected frequently to allow the transfer of machinery from one tractor to another.
