15 Pole Connector Between Towing Vehicles and Trailers with 12 Volt Nominal Supply

Truck and Bus Electrical Systems Committee
  • Ground Vehicle Standard
  • J2691_202002
  • Current
Published 2020-02-25 by SAE International in United States
This SAE Standard establishes the minimum construction and performance requirements for a 15 pole connector between towing vehicles and trailers, for trucks, trailers, and dollies, for 12 VDC nominal applications in conjunction with SAE J2742. The connector accommodates both power and ISO 11992-1 signal circuits along with dual ground wires to accommodate grounding requirements within the constraints of the SAE J2691 terminal capacity.

Seven Conductor Cable - Truck and Bus

Truck and Bus Electrical Systems Committee
  • Ground Vehicle Standard
  • J1067_202002
  • Current
Published 2020-02-25 by SAE International in United States
This SAE Standard establishes the minimum construction and performance requirements for seven conductor 1/8-1/10-5/12 cable for use on trucks, trailers and converter dollies for 12 VDC nominal applications. Where appropriate, the standard refers to two types of cables (Type F and S, described later in the standard), due to the variation in the performance demands of cables used in flexing and stationary applications.

Seven Conductor Cable for ABS Power - Truck and Bus

Truck and Bus Electrical Systems Committee
  • Ground Vehicle Standard
  • J2394_202002
  • Current
Published 2020-02-25 by SAE International in United States
This SAE Standard establishes the minimum construction and performance requirements for seven conductor 1/8-2/10-4/12 cable for use on trucks, trailers, and converter dollies for 12 VDC nominal applications. Where appropriate, the standard refers to two types of cables (Type F and S, described later in the standard), due to the variation in the performance demands of cables used in flexing and stationary applications. While the document’s title refers to ABS Power to differentiate the document from the SAE J1067 standard that it supersedes, the scope applies to both the primary green cable for powering ABS and lighting and the yellow auxiliary cable of the same construction.

Validation of a numerical procedure for fatigue assessment of a 325mm brake shoe

Master Sistemas Automotivos-Vagner Nascimento, Giovanni Teixeira
  • Technical Paper
  • 2019-36-0004
Published 2020-01-13 by SAE International in United States
The air brake system is still the most common brake system in use in heavy diesel vehicles. For safety and economic reasons it is imperative to understand the performance and durability (especially fatigue and wear) of every component of a drum brake, particularly the brake shoes. In applications where torque is lower than 20kNm brake shoes are made of ductile metals such as SAE 1030 steel. For such ductile materials Brown-Miller and Fatemi-Socie are the most recommended methods for fatigue crack initiation life prediction. The next pages discuss the validation of these fatigue methods in the case study of a 325mm brake shoe.
