标准摘要
[中文适用范围]： 本 SAE 推荐实践定义了在气压盘式制动器卡钳和 22.5 x 8.25 英寸盘式车轮之间建立尺寸兼容性的边界线，包括钢车轮上的弯曲气门杆和铝制车轮上制造商推荐的气门杆。该生产线建立了带阀杆包络线的最小轮，以实现互换性。该生产线不适合客户特定的车轮（例如 OEM 特定的风格化车轮）或客户特定的制动器。本文档仅讨论尺寸特性，未提及系统的性能、运行动态偏转或散热。系统集成商有责任确保卡钳、车轮和气门杆之间存在足够的间隙，以提供安全的操作条件。 SAE J694 中引用了上述安装系统。 [外文原描述]： This SAE Recommended Practice defines the boundary line for establishing dimensional compatibility between air disc brake calipers and 22.5 x 8.25 inch disc wheels, including bent valve stems on steel wheels and manufacturer recommended valve stems on aluminum wheels. The line establishes the minimum wheel with valve stem envelope to allow interchangeability. The line does not accommodate customer-specific wheels (such as OEM-specific stylized wheels) or customer-specific brakes.This document addresses dimensional characteristics only and makes no reference to the performance, operational dynamic deflections or heat dissipation of the system. It is up to the system integrator to ensure sufficient clearance exists between the caliper, wheel and valve stem to provide safe operating conditions. Mounting systems as noted are referenced in SAE J694.Cross Reference:
