Definitions

  • This invention relates to band tracks for selflaying track-type vehicles and is especially useful for farm tractors although the invention is also useful onmilitary and other vehicles.
  • Tracks proposed heretofore for resisting bending in one direction and thereby reducing the number of bogie wheels by supporting the vehicleupon the reach of track between relatively widely spaced guide wheels have had the disadvantage of being formed of metallic blocks or linkshinged to each other by pins in transverse openings in the links or blocks, and it has been found that due to the fact that high shear stresses were present at the hinge pins and also excessively high bearing pressures, lubrication of the pins has been difficult and rapid wear of the pins has objectionably lessened or destroyed the bridging ability of the track. The wear of the hinging parts has resulted in objectionable lengthening of the track and separation of the par s.
  • 'It is an object of the present invention to overcome the foregoing and other difliculties.
  • Fig. 1 is a, plan view of a portion of the track showing the wheel-contacting face thereof.
  • Fig. 2 is a side elevation thereof, partly in section taken on line 22 of Fig. 1.
  • Fig. 3 is a cross-sectional view thereof taken on line 3 3 of Fig. 1.
  • Fig. vl is a side elevation of the track on the vehicle.
  • the numerals l0, H designate flexible bands, which may be endless, of soft vulcanized rubber or other rubber-like material eachhaving a layer of flexible tension elements l2 embedded therein in spaced-apart relation and'bonded thereto. preferably of wire cable and completely surrounded by rubber-like material to protect them from moisture and to cushion them from each other and from the bogie wheels I3, l4 and other parts of the track.
  • the tension elements are' spaced apart intervals therealong, are metal straps I5 having ears [6 extending therefrom toward the center of thetrack and ears ll exteriding'i-outwardly toward'the'm'argin s of the tracl 'z i
  • the straps f5" r nay also havet'eibs l5a bent away from the strap toward the cables at the sides thereof for laterally confining the cables.
  • Shoes each comprising a metal plate l8. and a rubber tread l9 bonded thereto at one face thereof, are provided at spaced-apart intervals longitudinally of the track, and extend cross-wise thereof. 7
  • Each shoe is attached to the pair of bands H], II by means of bolts 20 which clamp the ears [6, H to the plate l8, spacers 2
  • the straps l5 are located above the tension members 12 so that these and the rubber-like material which surrounds them are confined between the straps l5 and the plate l8 with the rubber-like material surrounding them under slight compression sufiicient to hold the shoes in the desired spacing while at the same time the tension elements are each cushioned by surrounding rubber-like material.
  • the cables l2 and the metal'straps are connected to the rubber-like material by a vulcanized bond for transmission of driving forces between them without undue relative movement.
  • each plate l8 has a clearance opening 30 at its center for receiving a tooth of a drive sprocket 3
  • Each wear plate 32 has a pair of upstanding guide flanges 35, 36 flanking the opening 33.
  • the guide flanges have sprocketflanking portions 35a, 36a and. laterally offset portions 35b, 36b to provide sliding engagement with the portions 35a, 36a of adjoining flanges which they overlap and thereby steady the track in use against undesirable sidewise deflection.
  • the offset portions of flanges 35, 36 are of opposite hand.
  • the flange portions 35a, 36a are provided with laterally projecting lugs 40, 4
  • , 42, 43 are well spaced from the tension'members of the track, they carry the tension component of the bending stress of the track while the compression component is carried by the contacting wear plates, leaving the cable tension members to carry the driving forces.
  • the end faces'of the wearplates 32 haveinterlocking, notches 32cc. and the, lugs; 32 b. toi pro;- vide against lateral shifting relative to each other.
  • the abutting faces of the wear plates? are arranged so that a flange 36a of one overhangs the base of the adjoining wear plate as at 60 causing the wear plates torbeinterlockedvertically and preventing shifting. under shear. stresses.
  • , 42, 43 preferably have fiat contacting faces providing a broad area' for-'reduc'--- ing unit stress and abrasive wear. As the wear plates and their flangesiare bolted to the plates I8 theymay. be-individuallyremovedand replaced. incase. of: Wear orbreakage.
