Definitions

  • An anti-skid element for tires in the form of a pin made of wear-resistant material, a sleeve within which the pin is arranged and from one end of which the pin projects, and a sheath surrounding the sleeve.
  • the sleeve is made of a material which is a good heat conductor while the sheath is made of an elastic material which is a poor heat conductor.
  • spikes anti-skid elements
  • One such spike consists of a pin made of a wearresistant material which is arranged, generally by way of a press-fit, in a sleeve, the latter in turn being arranged Within a sheath.
  • the pin projects out of the sleeve, and the sleeve and sheath have an enlarged head at the end opposite to that at which the pin projects out of the sleeve.
  • the sheath is made of a ceramic material having negligible elasticity
  • the sleeve is made of a light metal
  • the pin which occupies the blind bore of the sleeve, is made of a wear-resistant material.
  • This arrangement reduces the amount which the rubber surrounding the spike is heated up, as compared to spikes where there are no sheathing means at all and where the light metal, which itself is a good heat conductor, is in direct contact with the rubber.
  • such spikes have the drawback that the outermost layer of the spike, i.e., the layer which is in direct contact with the rubber, is made of a material having negligible elasticity.
  • the primary object of the present invention to provide a spike or anti-skid element which overcomes the above-described drawbacks of the heretofore known spikes, namely, to provide a spike which will not allow the rubber within which the spike is embedded to be heated up unduly to the point where the rubber would deteriorate, and which resists the entry of foreign particles between the spike and the rubber.
  • the present invention resides, basically, in an anti-skid element for tires, which element comprises a pin made of Wear-resistant material, a sleeve made of a material which is a good conductor of heat, which pin is arranged in the sleeve and projects from one end thereof, the other end of the sleeve having an enlarged head, and a sheath which surrounds the sleeve, including its head.
  • the sleeve is made of an elastic material which is a poor conductor of heat.
  • the sheath will be made of a polymer, generally one having a heat conductivity of between approximately 0.1 and 0.4 kcaL/m. h. C.
  • the sleeve will be made of a material having a heat conductivity of between approximately and 400 kcal./m. h. C.
  • the ratio of the heat conductivity of the polymer to the heat conductivity of the material of which the sleeve is made will generally be between 1 to 500 and 1 to 2000, and preferably about 1 to 1000.
  • FIGURE 1 is a longitudinal view through an anti-skid element according to the present invention, the same being shown in a tire carcass.
  • FIGURE 2 is a transverse sectional view taken on line 22 of FIGURE 1.
  • FIGURE 3 is a transverse sectional view taken on line 3-3 of FIGURE 1.
  • the same show an antiskid element according to the present invention, the same comprising a pin 1 which is slightly conical and which is made of a hard, wear-resistant metal.
  • the pin 1 is pressfit into a sleeve 2 made of a light metal and projects from the lower end of the sleeve 2.
  • the pin 1 is shorter than the blind bore 3 of the sleeve 2 and can, if necessary, press itself further into the bore 3.
  • the sheath 6 is made of a material that has two significant characteristics: it is elastic and it is a poor conductor of heat, as compared to the material of which the sleeve is made, the latter being, for example, aluminum, copper, silver, or an alloy of any of these metals.
  • the sheath is made of a suitable polmer, such as polyethylene, polyvinyl chloride, a polyamide such as Perlon or nylon, polystyrene, polycarbonate, polypropylene, an acrylic resin such as Plexiglas, Orlon or Pan, polyisobutylene, polyvinyl ether, or polytetrafluoroethylene.
  • the press-fit can continue to be reinforced, which also contributes to the quiet running of a tire equipped with anti-skid elements according to the present invention, as well as to increased mileage which can be obtained from the tire.
  • the material of which the sleeve is made will have a heat conductivity of between approximately 100 and 400 kca'L/m. h. C., while the heat conductivity of the material of which the sheath is made will be much lower, namely, approximately 0.1 to 0.4 kcaL/m. h. C.
  • the ratio of the heat conductivity of the material of which the sheath is made to the heat conductivity of the material of which the sleeve is made will be between 1 to 500 and 1 to 2000, the preferred ratio being of the order of approximately 1 to 1000.
  • Table 1 sets forth several exemplary anti-skid elements according to the present invention and gives the heat conductivities of the materials of which the sleeve and sheath are made, as well as the resulting ratio of heat conductivities.
  • Zinc 155. 0.12. do... Polyvinyl ether, 0.11 l l l-l, 410 do Polypropylene, 0. 14... 1-1, 108
