Disc Wheel/Hub Or Drum Interface Dimensions- Commercial Vehicles
- Ground Vehicle Standard
This SAE Recommended Practice defines wheel mounting systems and documents, the dimensions and tolerances necessary to maintain serviceability, and interchangeability in the interface areas. To be consistent with ISO, it is divided into two sections (I & II). Section I is in concert with ISO 4107, describing mounting systems currently used internationally and nominated for, or included in, the international standards for bolt circle interfaces. Section II records information on current mounting systems also used in North America. Components of different mounting systems with common bolt patterns could be mis-assembled together and cause service problems. Therefore, it is important to note that each mounting system should be treated individually and their components not be intermixed.
Data Sets - Support Documents
The responsibility of the Truck and Bus Wheel Committee of the Truck and Bus Brake and Advanced Driver Assistance Systems Steering Committee is to initiate, develop, review and approve the recommended practices, standards, and information reports related to hubs, wheels and the wheel mounting systems of buses, trucks and tractor-trailer combinations intended for highway use. The Wheel Committee is constituted so as to be aware of other SAE wheel activity and to prevent duplication of effort.
