Definitions

  • a vehicle casing is made up of interconnected struc- [51] Km Ci I54! 5/06 tural members with each structural member compris- [58] Fieid S E a I 267/152 ing a plurality of flat plates arranged in adjacent 267/153, 85 280/152 spaced coplanar relation and encased in elastic material which holds the plates in flexibly interconnected 89/36 36 36 36 36 161/404 relation.
  • FIG. 1 shows a front view of a casing or cover according to the present invention.
  • FIG. 2 is a section taken along the line IIII in FIG. I, but on a larger scale than that of FIG. 1.
  • FIG. 3 shows a detail of FIG. 2 on a still larger scale.
  • FIG. 4 shows a detail of FIG. 1 in a scale corresponding to that of FIG. 3.
  • FIG. 5 is a section taken along the line VV of FIG. 4.
  • FIG. 6 represents a section along the line VI-VI in FIG. 4.
  • FIG. 7 shows a section taken along the line VII-VII of FIG. 1, on a scale corresponding to that of FIG. 3.
  • FIG. 8 is a section taken along the line VIII-VIII of FIG. 1 on a scale corresponding to that of FIG. 3.
  • FIG. 9 is a partial elevational view of a track-laying and wheeled vehicle provided with a casing or cover having features in accordance with the teaching of the present invention
  • FIG. 10 is a fragmentary cross sectional view taken along line X--X in FIG. 9.
  • the casing according to the invention is characterized primarily in that metal plates are embedded in the elastic material and at least on one side of the metal plates a fabric insert is provided.
  • the spaces between the metal plates make bending possible and the fabric insert ensures the stability of the form of the casing. Furthermore, the fabric insert increases the tearing resistance of the casing.
  • the fabric insert is drawn into the zone of the joint separating two adjacent metal plates in the direction towards the central plane of the metal plates, so that in the event of a buckling of the casing only a slight expansion or compression of the fabric takes place.
  • the edges of the metal plates are rounded off and are approximately semicircular. This ensures that even with a buckling angle of 90", no damage will occur to the elastic material and the fabric insert.
  • the fabric insert consists advantageously of a highly elastic plastic fabric with open meshes made from tearresistant individual threads.
  • a fabric By means of such a fabric the tearing strength of the casing is considerably increased, because the tear-resistant threads prevent a tearing of the elastic material itself if, as the result of mechanical damage, the elastic material has a cut in it.
  • the open meshes bring about an improvement in the separating strength of the layers
  • a further increase in the separating strength of the layers is achieved by drawing the fabric insert in the area of the holes towards the central plane of the metal plate.
  • the individual parts of the easing must possess the same shape.
  • the rear part of the casing it is desirable to design the rear part of the casing shorter, because otherwise when travelling through wet clay ground, the rear part can settle on the ground, which leads to greater wear of the casing and a loss in the driving performance of the vehicle.
  • the surface of the elastic material in the range of the separating joint between two adjacent metal plates is provided with a cut mark. As a result of this the casing can be adapted for any particular purpose at comparatively little expense.
  • the elastic material is provided with a hole in the area where two joints intersect, the elastic material having a thickened or reinforced area arranged concentrically around the hole.
  • the tearing of the casing in the zone of intersection of two joints can also be prevented by additional fabric inserts.
  • the elastic material advantageously consists of non-inflammable rubber.
  • each side edge of the casing there is provided at least one hole for fixing a connecting link.
  • the connection between two casings is generally effected by means of latches which are connected to each casing by means of a bolt.
  • An unintentional lifting off of the latches is prevented according to the invention by the fact that in the immediate vicinity of each hole provided on the side edge there is provided an elevation which serves as a catch and the surface of which preferably has the shape of a ball section.
  • a forceful stripping off of the latches by handicaps such as hedges, trees, etc. is prevented by providing a bead which extends over a quarter of a circle around the bore for connection of the connecting element.
  • cut markings are provided at a slight distance above the crank of the metal bar.
  • the lower edge of the casing is exposed to wear to a greater extent. For this reason, the lower edge of the casing is provided with a bead. At least one fabric insert or steel cable is embedded into the bead.
  • the connectingscrews of the casing may be damaged.
  • the plastic material is within the region of the casing where connecting screws have to be arranged, provided with a thickened or reinforcing section which is provided with a greater bore for receiving the beads of the connecting screws.
  • the casing according to the invention is of an elastic material having embedded therein metal plates 1 and fabric inserts 2 (FIGS. 1 to 3).
  • the edges 3 of the metal plates 1 provided with holes 4 are rounded off in a semi-circular form.
  • the fabric inserts 2 are drawn in toward the central plane of the metal plates 1.
  • the surface of the elastic material is provided with a cut mark 6 (FIGS. 4 to 6).
  • the plastic material is provided with a hole 7.
  • the elastic material has a thickened or reinforced portion 8 arranged concentrically around the hole 7.
  • a hole 10 for fixing a connecting link (not shown in the drawing).
  • an elevation 11 the surface of which has the shape of a spherical indentation.
  • a head 12 which forms more or less a quarter of a circle.
  • the elastic material has a thickened or reinforcing portion 19 which is provided with a larger hole 20 to receive the heads of the connecting bolts which are not shown in the drawing. (FIGS. 1 and 2).
  • FIGS. 9 and 10 clarify as to the extent of the casing and how the casing is attached to the vehicle.
  • the elevation 11 providing the form of a spherical segment serving to clamp a connection member designated with a reference C in FIG. 9 of the drawing.
  • the connection member C is rotatably arranged on a cover or cladding part A 1 by means of a screw or bolt D. If the connection member C is now swung over the adjacent cover or cladding part A 2, so the same finally reaches over the elevation 11 and becomes securely clamped. If the connection member C is again to be released, so there only needs to be a blow struck with a hammer, a stone or the like below the connection member C.
  • Bead 12 serves as a rib to hinder that along the cover or cladding there will be any objects engaging or rubbing thereagainst, for example, branches, which can come under the connection member and which could release or block the same.
  • the metal rod 13 is only to make possible the formation of a step upon requirement thereof.
  • the cover or cladding consists particularly of several cover or cladding parts which for reasons of manufacturing technicalities and for simplification of exchange of damaged cover or cladding parts are completely identical as constructed.
