This course studies one of the least known assemblies of a passenger car, the "drive axle", probably because of its near flawless performance over the many years of existence. Drive axles are mounted on the rear wheel centerline of front engine vehicles and on the front wheel centerline of front engine, four- wheel drive vehicles where they deliver engine power that provides vehicle mobility.

This course starts out with a description of drive axles and traces the flow of power from the vehicle engine to the drive wheels. Included in this line of events is the "differential". The differential is an ingenious device that was invented in 1885 and hasn't had any major changes since. The differential allows power to be sent to both drive wheels regardless of their rotational speed making rounding a corner a much smoother event than if there were no differential. The various types of drive axles and their internal components are examined along with an equation and graph that give an approximate size of the main right angle bevel drive gear and bevel differential gears that are inside a drive axle for a given application.

This course is written for Mechanical Engineers, Automotive Engineers, Power Train engineers, Design Engineers and any other discipline dealing with mechanical power transmission.
