Abstract
A tridem rear drive axle system (100) comprising a front-rear drive axle assembly (112) a middle-rear drive axle assembly (22) and a rear-rear drive assembly (24) is provided wherein torque is distributed substantially equally to each of the three rear drive axles. The front-rear drive axle assembly (112) includes a first input shaft (118) for driving the front-rear drive axle gear set and a second input shaft (114) for driving a through shaft (116) drivingly connected to the middle-rear drive axle assembly (22) which is of a standard forward tandem axle design. A transfer case (102) having a first output shaft (108) for connection to the first input shaft and a second output shaft (106) for connection to the second input shaft is provided. The transfer case provides twice the torque to the second transfer case output shaft than is provided to the first transfer case output shaft.
