Vehicle Application Layer

2017-08-15
WIP
J1939/71
The SAE J1939 communications network is developed for use in heavy-duty environments and suitable for horizontally integrated vehicle industries. The SAE J1939 communications network is applicable for light-duty, medium-duty, and heavy- duty vehicles used on-road or off-road, and for appropriate stationary applications which use vehicle derived components (e.g., generator sets). Vehicles of interest include, but are not limited to, on-highway and off-highway trucks and their trailers, construction equipment, and agricultural equipment and implements.   SAE J1939-71 Vehicle Application Layer is the SAE J1939 reference document for the conventions and notations that specify parameter placement in PGN data fields, the conventions for ASCII parameters, and conventions for PGN transmission rates.

CURRENT
J1731_201708
This SAE Recommended Practice describes STANDARD-DUTY and EXTREME-DUTY Pilot Bearing requirements and sizes for class 6, 7, and 8 on-highway trucks and buses that use diesel engines and manual transmissions. The recommendations may apply to a wide range of other pilot-bearing applications, such as agricultural, industrial, and construction equipment.

SAE Nodal Mount

2017-08-14
CURRENT
J1134_201708
This SAE Recommended Practice establishes a single bolt pattern for the No. 1 clutch housing (see Figure 1) and the No. 2 clutch housing (see Figure 2). These four bolt patterns are designated to give commonality of mounting brackets in existing frame rails. The 420 mm (16.5 in) span, pad face to pad face, allows the ease of installation in existing frame rail widths. This is also the minimum spacing which will accommodate commonly used clutches.

Truck Tractor Semitrailer Interchange Coupling Dimensions

2017-08-09
CURRENT
J701_201708
The information in this SAE Information Report is the result of studies by the Automobile Manufacturers Association, American Trucking Association, and Truck Trailer Manufacturers Association, to achieve interchangeability of equipment which will comply with the legal dimensional limitations for the majority of states and yet permit increased loading space within these dimensions. This in no way supersedes other information in the SAE Handbook on this subject. Some cases will require more care in application allowing splash shield clearance at trailer support interference points and positioning fifth wheel to allow trailer swing clearance on an 11% grade. All dimensions are given in inches. Table 1 and Figures 1 and 2 show basic requirements for interchangeability of truck tractor and semitrailer equipment. Figure 3 shows the interchangeability of the doubles converter dolly.

Measuring Energy Consumption, Fuel Economy and Emissions of Conventional and Hybrid Medium/Heavy-Duty Vehicles using a Powertrain Dynamometer

2017-06-22
WIP
J2711/2
This SAE Recommended Practice was established to provide an accurate, uniform and reproducible procedure for simulating use of MD/HD conventional vehicles and hybrid-electric vehicles (HEVs), as well as plug-in hybrid-electric vehicles (PHEVs) and battery electric vehicles (BEVs) on powertrain dynamometers for the purpose of measuring emissions and fuel economy. This document does not specify which emissions constituents to measure (e.g., HC, CO, NOx, PM, CO2), as that decision will depend on the objectives of the tester. While the main focus of this procedure is for calculating fuel and energy consumption, it is anticipated that emissions may also be recorded during execution of this procedure. It should be noted that most MD/HD powertrains addressed in this document would be powered by engines that are certified separately for emissions. The engine certification procedure appears in the Code of Federal Regulations, Title 40-§86 and §1065.
