Definitions

  • PATENTS draulic motors drive two symmetrical sections of a 3,468,041 9/1969 Mattson et a1.
  • FIG. 1 is a schematic front view of a snow plow according to the invention, partly in section, taken along lines I-I in FIG. 2;
  • FIG. 2 is a fragmentary section taken along lines lIIl in FIG. 1.
  • the new snow plow 1 is mounted in front of a suitable vehicle 2, which canbe-conventional.
  • the new snow plow drum structure comprises a pair of drums 3a, 312, each having the usual snow propelling ribs, as schematically shown at 3c and having inner ribs 20 for mounting the drum wall on a central hub 21.
  • Each hub 21 is rotatably supported by ball bearings 22 on a stationary hollow axle 23.
  • the hollow axles extend, inwardly, along the axis of the drum structure, from hubs 21 to an inner area where they, by radial ribs 24 are secured to a stationary carrier ring 25. This ring, as shown in FIG.
  • a drive shaft 4 for the two drums extends through hollow axles 23.
  • This shaft has flange means 28' on its outer ends whereby it is secured by simple bolts to the outer ends of hubs 2].
  • shaft 4 has a drive gear 5 secured thereto, which meshes with pinions of two hydraulic motors 7 and 8.
  • the two motors 7 and 8 are secured to a central rib or plate 30 peripherally held on or integral with carrier ring 25.
  • plow unit 1 and frame or shell 26 thereof have carrier or connector plate 31, on a rear surface of this unit, for securer nent thereof to corresponding connector means in front of vehicle 2.
  • These connector means are not a part of this invention.
  • An additional system of braces 32 can also be used for connecting the plow unit to the vehicle.
  • inlet and outlet valves 9 and 10 are directly connected, within the drums, to-both hydraulic motors by means of .pipes 12 13, 14, 15. These pipes are suitably supported from the nonrotating snow plow structure 25, inthe drum.
  • Valve 10 through a pipe or hose or other duct 11 receives hydraulic fluid under pressure, through a hollow part 27a of this structure, from a suitable pressure generator, not shown, which advantageously is mounted in vehicle 2 and connected to the drum unit by control connector 17, 18.
  • the connector is shown as having return duct 16 as well as duct 11, and of course is connected with the generator by suitable hoses or the like, not shown.
  • the ducts are SU'COhnCCtCd that the two hydraulic motors in-the illustrated embodiment can operate in parallel.
  • valves 9 and 10 can have conventional three-way.mechanisms. Thereby either hydraulic motor can be operated alone, when the snow load is such as to allow such operation. To this end, arrangements of course can be made to control the threeway valve from' the drivers seat in vehicle 2. In other cases a single hydro-motor, for example motor 7, may suffice and valves 9 and 10 in such case only serve as ON, OFF valves. In such case, gear 5 is not always needed and the hydraulic motor can also be mounted on shaft 4.
  • a snow plow structure comprising:
  • a rigid support structure for said drums comprising a plate generally vertically extending between the drums of said pair;
  • drive means for the drums disposed within the drums and comprising a drive shaft common to and centrally disposed within the aforesaid drums; a rotor for driving said shaft, adjacent said plate; and a plurality of hydraulic motors distributed in the space within the drums for driving said rotor; and
  • valve means for controllably and selectively connecting said hydraulic motors to a source of drive energy outside the drums, said valve means being operatively connected to said motors.
  • a snow plow structure according to claim 1, wherein said support structure includes a hollow axle for each drum, said axle being rigid with said plate, being concentrically disposed within the drum and h'av ing one part of said drive shaft centrally disposed therein and connected to the drum at the outer end of the shaft.
  • Av snow plow structure according to claim 1, wherein the rotor of said drive means is a gear having said shaft rigidly connected thereto;.every one of said plurality of hydraulic motorshaving a drive pinion in mesh with said gear.
