ABSTRACT:
An auxiliary drive assembly for use with a vehicle having a drive shaft and a driven shaft. The auxiliary drive assembly includes a flywheel as a source of energy. First and second hydraulic pump/motor units are hydraulically coupled to each other. Summation gearing is provided having a first input connected to the flywheel and to the first motor/pump unit, a second input connected to the second motor/pump unit, and an output from which power can be released. The summation gearing output can be connected to the drive shaft, by means of a releasable coupling, for driving the drive shaft or charging the flywheel. The second motor/pump unit has a brake so that the flywheel can be charged very rapidly by the drive shaft. The drive shaft and driven shaft can be separated to further increase the speed of charging the flywheel.
