Definitions

  • the invention relates to a spike for the tread of a vehicle tire according to the preamble of claim 1.
  • Spikes for the tread of a vehicle tire, in particular a winter tire are known in various designs.
  • All spikes consist of a body that can be at least partially inserted into the tread of the vehicle tire.
  • holes are usually provided in the tread of the vehicle tire at a predetermined location, into which the spikes can be pressed with great force. Since the tread of a vehicle tire is usually composed of an elastic material, in particular rubber, the holes are expanded so reversibly when the spikes are inserted that the elastic material rests on the spikes over the entire surface after the spikes have been introduced and the spikes in the Tread of the vehicle tire holds.
  • the body of this spike comprises a plate-shaped root, with which the spike is anchored near the upper belt layer in the vehicle tire and which has the largest diameter of the spike parts.
  • the root is usually connected to a spike upper part via a neck part, wherein the spike upper part usually consists of a thicker spike part and a spike tip which is tapered in relation thereto and which usually protrudes from the running surface.
  • the spike tip can be a pen that is in the
  • All parts of the body introduced into the running surface are cylindrical, that is to say they have two base surfaces which are parallel, flat, congruent and connected to one another by a lateral surface.
  • the base areas can differ before having shapes such as a circle, a triangle, a square, a rectangle, or an oval.
  • a disadvantage of the known spikes is that when the vehicle tire is used on a snow or ice surface or on a surface with dirt particles, despite their root anchoring, they fall out relatively quickly from the tread of the vehicle tire or at least perform relatively large movements in the tread. This leads disadvantageously to the fact that the desired effect of the spikes is lost relatively quickly and that the vehicle tire provided with the spikes has a short lifespan.
  • the object of the invention is to provide a spike which has better grip in the tread of the vehicle tire.
  • the invention is based on the knowledge that when using the vehicle tires provided with conventional spikes, snow, ice and or dirt particles get into the space between the spike and the elastic material of the tread on a snow, ice and or dirt-containing surface. This leads to the elastic material of the tread being pushed away from the sink. The particles in the gap then form a kind of lubricant and reduce the adhesion of the spikes in the tread such that they fall out of the tread or move strongly.
  • the part of the body which can be introduced into the running surface is at least partially conical or frustoconical, the base surface of the conical or frustoconical part of the body introduced into the running surface points inside the vehicle tire, better adhesion of the spikes in the tread is achieved in a surprisingly simple manner.
  • the movement of the spikes within the tread is also reduced, so that the durability and the service life of the vehicle tire are increased overall.
  • a lower spike force has an advantageous effect on the ground, so that less road abrasion occurs.
  • the angle ⁇ is understood to mean the angle between the lateral surface and the base surface of the conical or frustoconical part, which is between 1 and 89 °, preferably between 20 and 70 °, particularly preferably between 30 and 50 °.
  • the base of the conical or frustoconical part can be circular, elliptical, triangular, square, hexagonal, polygonal or star-shaped.
  • a further development of the invention provides that the conical or frustoconical part is straight or crooked.
  • the conical or frustoconical part preferably forms the main part, that is to say the largest part of the body introduced into the tread.
  • the large surface of the conical or frustoconical part ensures a large vertical force and thus a correspondingly high adhesion of the spike in the tread of the vehicle tire.
  • the body introduced into the tread of the vehicle tire preferably comprises a pin which is embedded in the body in a positive and / or non-positive manner and with one end protruding from the tread of the vehicle tire, the pin preferably protruding Hard metal, sintered metal or the like is made.
  • the body of the spike is preferably made of metal, plastic or other wear-resistant materials.
  • FIG. 1 shows a spike according to the prior art in a) side view and in b) front view
  • FIG. 2 shows a spike according to the prior art in a) side view and in b) front view
  • FIG. 3 shows a spike according to the prior art in a) side view and in b) end view
  • FIG. 5 shows a spike according to the invention in a) side view and in b) front view
  • FIG. 6 shows a spike according to the invention in a) side view and in b) front view
  • FIG. 7 shows a spike according to the invention in side view
  • Fig. 8 shows a spike according to the invention in side view.
  • FIG. 1 to 3 each show a sink according to the prior art in a) side view and in b) end view, the same reference numerals designating the same parts.
  • the spikes shown in FIGS. 1 to 3 for the tread 1 of a vehicle tire, not shown here, consist of a body 2 which is at least partially inserted into the tread 1 of the vehicle tire.
  • the body 2 comprises a plate-shaped root 7 with which the spike is anchored in the vehicle tire in the vicinity of the upper belt layer (not shown here) and which has the largest diameter of the spike parts 6, 7, 8 or 9.
  • the root 7 is connected in Fig. 1 via a neck part 8 and in Figs. 2 and 3 directly to an upper spike part, the upper part of the spike consisting of a thicker spike part 9 and a tapered pin 6 which is embedded in the spike part 9 and from the tread 1 protrudes.
  • All parts 6, 7, 8 or 9 of the body 2 introduced into the running surface 1 are cylindrical, that is to say they have two base surfaces which are parallel, flat, congruent and connected to one another by a lateral surface.
  • the base areas can have different shapes.
  • all parts 6, 7, 8 and 9 are circular in cross section.
  • the root 7 and the spike part 9 are circular in cross section, the pin 6, however, is square in cross section.
  • the root 7 and the spike part 9 are oval in cross section and the pin 6 is hexagonal in cross section.
  • FIGS. 4 to 6 each show a spike according to the invention in a) side view and in b) end view, the same reference numerals designating the same parts.
  • the body 1 shown in Fig. 4 comprises a plate-shaped root 7, which is connected via a neck part 8 to an upper part of the sink, the upper part of the spike consisting of an annular projection 10, a frustoconical part 4 according to the invention and a pin 6 which is embedded in the frustoconical part 4 and protrudes from the tread 1. While the root 7 and the pin 6 are oval in cross-section, the annular projection 10 and the frustoconical part 4 have a circular cross section.
  • the body 2 shown in FIG. 5 also comprises a plate-shaped root 7, which is connected directly to a spike upper part, the upper part of the purge consisting of a frustoconical part 4 according to the invention, which has an annular projection 10, and a pin 6, which is in the frustoconical part 4 is embedded and protrudes from the tread 1. While the root 1, the frustoconical part 4 and the annular projection 10 are circular in cross section, the pin 6 has a triangular cross section.
  • the body 2 shown in FIG. 6 has a very simple structure and consists only of a frustoconical part 4 with a square cross section and a pin 6 with a circular cross section, the pin 6 being embedded in the frustoconical part 4 and protruding from the tread 1.
  • FIG. 7 shows a spice according to the invention in a side view. In principle, this corresponds to the spüce shown in FIG. 1 in a) side view, the same reference numerals designating the same parts.
  • the spike in FIG. 7 differs from the spike in FIG. 1 according to the invention in that a truncated cone-shaped part 4 is provided instead of the cylindrical, thicker spike part 9.
  • the frustoconical part 4 of the body 2 shown in FIGS. 4 to 7 improves the adhesion of the spices in the tread 1. This is due to the changed force distribution of the elastic material of the tread 1 acting on the frustoconical part 4 of the washing body 2. 8, namely a vertical force F (s) x cos ⁇ and a radial force F (s) x sin ⁇ , with a resulting vertical force F (S TOT A) X cos ⁇ Spike presses inside the vehicle tire.
  • the spüce shown in side view in FIG. 8 corresponds in structure to the spüce from FIG. 7, with the same reference numerals designating the same parts.
