HYBRID TANDEM DRIVE AXLE OF A TRUCK VEHICLE

摘要

A tandem rear axle (28) suspended from a chassis frame (12) rearward of front steerable wheels (22, 24) has a first drive axle (30) with a driven wheel (32) on the right side and a driven wheel (34) on the left side and a second drive axle (36) rearward of the first drive axle and having a driven wheel (38) on the right side and a driven wheel (40) on the left side. A drivetrain couples a combustion engine (26) to the first drive axle for driving its driven wheels. A prime mover (52, 68, 70, 74) other than the combustion engine drives the driven wheels of the second drive axle.
