Claim 8:
9. A steerable drive wheel assembly comprising:
an outer housing defining a sheltered interior space,
an intermediate suspension module disposed at least partially within said sheltered interior space of said outer housing,
a drive module disposed below said intermediate suspension module, said drive module including a first drive subassembly having a first wheel and a second drive subassembly having a second wheel, said first and second wheels supported in a side-by-side orientation for independent rotation about a common horizontal axis,
a rotary bearing operatively disposed between said drive module and said intermediate suspension module for enabling rotational movement of said drive module relative to said intermediate suspension module about a generally vertical steering axis, and
a serpentine energy chain disposed generally co-planar with said rotary bearing,
wherein said first drive assembly includes a first drive motor operatively connected to said first wheel through a first transmission, said second drive subassembly includes a second drive motor operatively connected to said second wheel through a second transmission, each of said first and second drive motors having an armature and a stator body, and wherein each of said armatures are disposed for rotation in respective axes parallel to said common horizontal axis.
