Abstract
An efficient direct drive system is featured which is easier to maintain than conventional systems. The system includes a drive assembly which employs a hydraulic motor to rotate a shaft assembly and power most or all of the drive chains of the vehicle's endless track assembly at once. A laterally located motor directly rotates the shaft assembly. A gear assembly is included in the drive system. A brake assembly may be included in the system. The shaft assembly is made up of an inner shaft and an outer shaft sleeve which are disposed over portions of the inner shaft. Laterally outer drive sprockets are bolted or otherwise affixed to the outer shaft sleeve. The inner shaft and outer shaft sleeve are further keyed together so that the shaft assembly is rotatable as a unitary piece. The shaft assembly may be easily dismantled to change the laterally outer sprockets when necessary.
