On this quillare the motor bearings which preserve the correct relation of arma-ture and field. On each end of the quill is a plate, see Fig. 258,from which project seven round pins. These pins fit very looselyin corresponding sockets on the inside of each wheel hub, which ismade very large for the… … Fig. 255. View of Truck without Motors of the armature is transmitted to the driving wheels through theseeccentric springs.
