Abstract

138,686. Leadbetter, T. A. N. Jan. 30, 1919. Driving steering-wheels; differential gearing.- For land and road haulage a tractor can be fitted with separate alternative sets of front driving and steering wheels provided with internal and external gears respectively adapted to mesh with separate driving pinions, by which means different gear ratios are obtained. The wheels are driven from a differential gear, which is movable to bring two bevel gears thereon alternatively into mesh with a driving bevel gear, to ensure a forward drive in both cases. Fig. 1 shows a land wheel 14 fitted at one end of the front axle, and a road wheel 16 at the other end. The land wheels 14 have internally-toothed gears 13 driven by pinions 12, while the road wheels 16 are driven by pinions 11 in mesh with externally-toothed rings 15. The pinions 11, 12 are carried on shafts parallel with the stub-shafts 9, and are driven by bevel gears 7 in line with the steering-axes, the gears 7 being driven in turn by bevel-gears 6 on the differential shaft 5. The differential is moved to effect a forward drive by means of a fork operated by a hand-operated cam.
