中型和重型公路车辆的中央轮胎充气系统的管理(CTIS)类型

[中文适用范围]： 该 SAE 推荐实践定义了用于评估地面车辆 CTIS 功能和性能的系统和组件功能、测量指标和测试方法。这种类型的系统允许驾驶员根据非公路条件选择操作轮胎压力设定点（TPSP），并且在返回公路操作时将充气压力维持在车辆指定水平。建议使用这些系统来解决原始设备制造商和/或特种车辆制造商最初安装在车辆上的所有可维修轮胎的问题，并且对于售后市场（包括更换或备件），建议（但可选）解决所有轮胎/轮辋组合的问题在车辆首次销售或使用日期后安装。用于军事和一些其他非常严格的越野应用的系统需要如此极端的性能要求，特别是在非常高和低温以及其他基于战斗的极端条件下，使得此类应用可能超出主题文件的推荐参数。在这些情况下，采购客户、车辆 OEM 和适用组件 OEM 有责任确定可能需要哪些妥协，以及可能超出此处推荐的设计和性能解决方案的适用性。本文件适用于以下车辆类型的所有车轴和所有车轮组合，但不排除其在其他车辆类型上的使用 - 超过 7257 千克（16,000 美式磅）车辆额定总重 (GVWR) 的单体动力车辆，以及多动力车辆-单元车辆组合，最多三 (3) 个牵引单元，使用 SAE J560 连接器进行供电和/或通信，或等效的后继连接器技术。对于包括两个或更多拖车的组合车辆，还包括移动车轴。所包括的车辆可以是新制造的车辆或现有车辆，配备空气或液压制动系统。特别提示：此类车辆通常使用称为“双轮胎均衡器”的设备。安装CTIS系统时，不建议使用双轮胎均衡系统，因为它们与管理系统的目的背道而驰。注意：本版本的主题文档未涉及以下系统。 1. 轮胎压力监测系统 - 这些系统已根据 SAE J 2848-1 进行处理； 2. 轮胎压力维护系统 - 这些系统已根据 SAE J 2848-2 进行处理。 [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 ground vehicle central tire inflation systems (CTIS), also known as tire pressure management systems or tire pressure control systems (TPCS). Systems of this type allow the driver to select the operational tire pressure set point (TPSP) based on vehicle load and surface type (highway, off-highway, off-road, etc.) and maintain the inflation pressure to the vehicle specified level.These systems are recommended to address all serviceable tires as originally installed on a vehicle by the OEM and/or specialty vehicle manufacturer, and for the aftermarket (including replacement or spare parts) are recommended (but optional) to address all tire/rim combinations installed after initial vehicle sale or in-use dates.Systems for use by military and some other very rigorous off-road applications require such extreme performance requirements, particularly at very high and low temperature and other combat-based extremes that such applications may fall outside the recommended parameters of the subject document. In those cases, it is the responsibility of the procuring customer, vehicle OEM, and applicable component(s) OEM to determine what compromises might be required, and the suitability of design and performance solutions that may be outside of those recommended here.This document is applicable to all axle and all wheel combinations for the following vehicle types, but does not preclude its use on other vehicle types—single unit powered vehicles exceeding 7257 kg (16000 U.S. pounds) gross vehicle weight rating (GVWR) and multi-unit vehicle combinations, up to three towed units, which use an SAE J560 connector for power and/or communication, or equivalent successor connector technology. For combination vehicles including two or more trailers, the dolly axles are also included. The included vehicles can be newly manufactured vehicles or existing vehicles, fitted with air or hydraulic braking systems.Cross Reference: 47CFRPart15,49CFRPart393,ASTMB117,ASTMB117-07,ATA/TMCRP-235A,FMVSS101,FMVSS120,FMVSS121,ISO/IEC2575,J1211_201211,J1455_201208,J1455_201703,J1609_201410,J1939_201206,J1939_201308,J2334_201604,J2402,J2721_202305,J2848-1,J2848-2,J2848/2_202303,J560_201604
