标准摘要
[中文适用范围]： 本国际标准规定了轻型拖车或大篷车与牵引车（当后者装有连接球时）之间机械连接装置兼容性所需的尺寸。 连接球周围的间隙空间旨在允许被牵引车辆的连接和分离，以及机械装置连接和分离过程中的安全操作。 本国际标准适用于设计用于将 O1 和 O2 1) 类大篷车和轻型拖车与 M 或 N 类车辆连接的连接球。 它不一定适用于由特种车辆牵引的特种拖车。 [外文原描述]： ISO 1103:2007 lays down the dimensions necessary for the compatibility of mechanical coupling devices between light trailers or caravans and towing vehicles, when the latter are fitted with a coupling ball. The clearance space around the coupling ball is intended to allow coupling and decoupling of towed vehicles, as well as safe operation during coupling and uncoupling of mechanical devices. ISO 1103:2007 applies to coupling balls designed to couple caravans and light trailers of categories O 1 and O 2 to vehicles of categories M or N. It does not necessarily apply to special trailers drawn by special vehicles.
