All-Wheel-Drive Drivetrain Schematic Symbol Standards
In this SAE Recommended Practice, attention will be given to passenger cars and light trucks (through Class III). The purpose of this recommended practice is to define standardized symbols that describe the arrangement and function of drivetrain systems and components of all-wheel-drive vehicles. This document presents basic symbols, superimposed symbols and symbols with modifiers. Various vehicle drivetrain schematics are shown with specific component arrangements or general driveline layout to illustrate varying levels of descriptive intent.
Rationale: J2059 meets the requirement of its original intended purpose. As such, it provides a method of describing Driveline system concepts in schematic form. As a compilation of symbols, it provides an introduction to the components normally associated with All Wheel Drive technology.
