Definitions

  • the surface area of spikes may be too small to be effective on ice surfaces that are too hard for the spikes to penetrate. Likewise spikes are relatively ineffective on powder snow.
  • Planar cleats may reduce ground contact area on icy surfaces and have little or no resistance to lateral forces, such as those induced by side hills, turns or uneven braking.
  • my cleats include a traction increasing flange which resists lateral forces imposed on the vehicle by inertial forces or gravity during turning or skidding, or due to changes in terrain or the degree of compaction of its surface.
  • the flanged portion of each cleat resists such lateral forces by including a pair of terrain engaging planar flanges, or blade portions, which diverge outwardly and backwardly from a central portion of the cleat with respect to the driving direction of the vehicle whether mounted on an endless track as on a snowmobile, or a rotatable tread, as on an all-terrain vehicle.
  • the diverging planar surfaces are at an obtuse angle to each other from the central portion of the base plate of the cleat so that the central portion of the blades, whether solid between the surfaces, or gapped, strike the ground first in normal forward drive.
  • This action exerts a downward and backward compression of unconsolidate ground or snow to lift the tread and the vehicle as they move forwardly.
  • any tendency of the tread or vehicle to slip sideways is resisted by both diverging planar surface converting the lateral force components acting on the flange to a normal component in the direct line of drive or braking, whether traveling on a side- or down-hill and over areas of firmer ground or snow.
  • the two angled, planar surfaces tend to pack the surface both forwardly and latterly toward the central area between the two planes. This substantially improves braking of a vehicle in addition to increasing safety by reducing skidding or side slipping, on harder plane surfaces or on hilly terrain.
  • the blade portions have an obtuse angle therebetween so that in normal drive, the central portions the flange first contacts the terrain surface, during propulsion of the links of the endless track or cylindrical tread and thereby increase the longitudinal and lateral resistance of the track or tread to slippage transverse to the direction of travel on surfaces of varying hardness or inclination.
  • each cleat is an article of manufacture for increasing traction between an endless track and the earth's surface, wherein the cleat has an elongated base plate forming one surface mountable on a drive link of an endless track or the like and the drive surface of the base plate has a paddle portion extending longitudinally therealong which includes at least a pair of blade sections extending laterally from the central area of the drive surface so that they form an obtuse angle therebetween.

  • Fig. 4 is a bottom plan view taken in the direction of arrows 4-4 in Fig. 1 showing a preferred arrangement of a plurality of cleats of this invention mounted on different links of the track so they are spaced laterally and longitudinally from each other across the width and length of the endless track.

  • cleats 50 are preferably mounted so that obtuse angle 22, between blades 18 and 20, is directed so that the outer ends contact the drive surface first, or backwardly from the direction of drive, for maximum effectiveness.
  • cleats are used on ice, or other hard surfaces, compaction of snow or the like, within the obtuse angle between the blades is not a problem.
  • the advantages of the present invention are available on balloon tire treads, in unconsolidated or hard surfaces, to improve both braking and forward propulsion of a vehicle.
  • each cleat 10 is attached to a link 11 by bolts 36 which pierce link 11 through a cylindrical bore 35 each of which corresponds in location to conical bores 33 through base plate 16.
  • the axis of bore 33 is desirably canted toward the forward surface of blades 18 and 20 to facilitate mounting on a link 11 of belt 12 without removal of the latter from the endless track of snowmobile 14.
  • a shape for holes 33 or 52 aids installation on a link, without access to either the flat upper or lower surfaces of belt 12.
  • Bolts 36 are secured, as by nuts 38 and lock washers 40.
  • cleats of the present invention are cast as a unit in a single mold from thermoplastic polyurethane, or polyether, having a Shore hardness of about 90A to 50D molecules of stiffness up to about 100,000 psi and a tensile strength of about 5,000 to 10,000 psi and at temperatures down to -20*C.
  • Figs. 11 to 13 illustrates a further embodiment of the invention wherein the paddle or blade portions, 18 and 20, are wider or longer so that they are more flexible, relative to the dimensions of base plate 16.

Abstract

Cette invention concerne des crampons (10) montés sur des chenilles sans fin ou bandes de roulement (12) pour améliorer à la fois la traction et le freinage lorsque des forces latérales néfastes produisent un glissement et une perte de traction. Chaque crampon comprend une partie à brides de prise qui se caractérise en ce que son bord externe se présente sous la forme d'une paire de surfaces planes (18, 20) qui divergent vers l'extérieur et vers l'arrière depuis une partie centrale (26) du crampon par rapport au sens normal de marche du véhicule.
