Abstract

A multiple rear drive axle system for a vehicle includes a first axle coupled with a drive shaft from a transmission of the vehicle. The first axle includes a first cantilevered input pinion mechanically coupled with the drive shaft and with a first driven gear. The system also includes an output shaft mechanically coupled with the drive shaft. A second axle has a second cantilevered input pinion mechanically coupled with the output shaft of the first axle system and with a second driven gear. The first and second input pinions are common, that is, are substantially identical pinions. The first and second driven gears are also common, that is, are substantially identical gears.
