适用于总重量低于 26000 磅的拖车的轮胎压力和温度监测系统

[中文适用范围]： 本 SAE 建议做法定义了系统和组件功能、测量指标和测试方法，用于评估在已知操作环境下用于总重量低于 26000 磅的拖车的轮胎压力系统的功能和性能。本文件适用于总重量低于 26000 磅的所有被拖拖车。被拖拖车的例子包括休闲车旅行拖车和第五轮拖车、多用途拖车、货物拖车、牲畜拖车、平板拖车、船拖车和雪地摩托拖车。这些拖车可以配备一个、两个或三个车轴，每个车轴支撑两个或四个轮胎。建议使用这些系统处理原始设备制造商最初安装在拖车上的所有正在使用的轮胎。本建议做法还可应用于外部 TPMS，该 TPMS 也同时涵盖牵引车和拖车。本文件将重点介绍监测类型的轮胎压力系统。 [外文原描述]： This SAE Recommended Practice defines the system and component functions, measurement metrics, and testing methodologies for evaluating the functionality and performance of tire pressure systems for use on trailers under 26000 pounds GVWR within the known operating environments. This document is applicable to all towed trailers under 26000 pounds GVWR. Examples of towed trailers are recreational vehicle travel trailers and fifth wheels, utility trailers, cargo trailers, livestock trailers, flatbed trailers, boat trailers, and snowmobile trailers. These trailers can be equipped with one, two, or three axles with each axle supporting either two or four tires. These systems are recommended to address all tires in service as originally installed on a trailer by the OEM. This recommended practice can also be applied to external TPMS that also cover tow vehicles and trailers simultaneously. This document will focus on tire pressure systems of the monitoring type.
