标准摘要
[中文适用范围]： 本文件旨在根据安装的硬件对所有轮驱动（AWD）架构进行分类，不考虑控制和软件的实施。例如，动力传输单元（PTU）可能配备能够进行扭矩管理的离合器，但控制实施仅使用其进行断开功能而不进行扭矩管理。 在SAE推荐实践中，将关注乘用车和轻型卡车（至III类）。此处提出的定义也可能适用于重型卡车（4至8类）和使用多于两个车轴的非公路应用，但主要关注乘用车和轻型卡车。 定义的目的是概述基本术语并对AWD概念进行分类。目标是给该领域的工作人员提供一个讨论AWD系统类型的共同基础，独立于营销术语。 [外文原描述]： This document seeks to classify all-wheel drive (AWD) architectures primarily based on the installed hardware and does not consider the implementation of the controls and software. For example, a power transfer unit (PTU) may be equipped with a clutch that is capable of torque management, but the control implementation only uses it for disconnection functions without torque management. In this SAE Recommended Practice, attention will be given to passenger cars and light trucks (through Class III). The definitions presented herein may also be applicable to heavy trucks (Class 4 through 8) and off-highway applications using more than two axles but are primarily focused on passenger cars and light trucks.Cross Reference:
