Definitions

  • the invention concerns a weblike traction member for a tire chain which has a weblike body that is apertured for receiving connecting links of the chain and with the roadway engaging edge of the body being provided with protruding regions distributed therealong and with at least one of said regions having inclined lateral walls and sharp edges about the periphery of the face thereof that engages the roadway.
  • the present invention relates to a web member for tire protective chains with supporting members provided at the bottom side of said web member and extending in longitudinal direction one behind the other, said supporting members forming the bottom running surface while an intermediate supporting member which protrudes beyond the outer supporting members has inclined lateral surfaces which are, for instance, plane surfaces.
  • FIG. 1 illustrates a view of a web member according to the present invention.
  • FIG. 2 is a section taken along the line 11-11 of FIG. 1.
  • FIG. 3 illustrates a view of a web member somewhat modified over than of FIG. 1.
  • FIG. 4 is a section taken along the line IV-IV of FIG. 3.
  • FIG. 5 is a bottom view of the web member of FIG. 3.
  • the web member according to the present invention which is provided with supporting members arranged at the bottom side of said web member one behind the other while an intermediate supporting member protrudesbeyond the outer supporting members and has, for instance, plane lateral surfaces, is characterized primarily in that the said lateral surfaces are inclined so as to taper in a direction away from the bottom toward each other.
  • the lateral edges of the supporting members will form sharp edges formed by surfaces arranged at an acute angle with regard to each other which in addition to having a high wear resistance willassure a sufficient grip even on smooth and hard ground over which the web member moves.
  • the bottom surface of the-supporting members wears there will, in contrast to heretofore known web members of the type involved, not exist the danger that the edges will become rounded by such wear. Instead the edges form self-sharpening and therefore always sharp. edges with the necessary or desired safe gripping effect.
  • a plurality if supporting members when seen in the longitudinal direction of the web member, have an approximately trapezoidal contour while the bottom running surface is narrower than the thickness of the link member.
  • FIG. 1 illustrates a web member 1 according to the invention which has a plate or web-shaped link body 2.
  • the running side of the web member 1 is provided with three supporting-members 3, 4 which, when viewed in the longitudinal direction of the web member as indicated by the arrow 5, are located one behind the other.
  • the web member 1 is symmetric not only to its longitudinal central plane 6 but also to a plane 7 perpendicular to said longitudinal central plane 6.
  • the two outer supporting members 3 are thus equally spaced from the intermediate supporting member 4 which as far as the running side of the web member-'1 is concerned protrudes beyond the outer supporting members 3 and thereby has a greater gripping effect.
  • the lateral surfaces 8 of the link body 2 are substantially plane and are parallel to each other.
  • the lateral surfaces of the outer supporting members 3 are located in the plane of the lateral surfaces 8 of the link body 2 while the outer supporting members 3 each have acommon end face with the link body I 2.
  • the other end face 10 ofeach outer supporting member 3 is parallel to the endface 9 of the link body 2 so that the outer supporting members 3 in side view as well asin end view have a simple rectangular shape.
  • Those surfaces 11 of the outer supporting members 3 which are located on the running side of the web member 1 are arranged in a common plane which is vertical to the longitudinal central plane 6 and to the plane of symmetry 7.
  • the lateral surfaces 12 of the intermediate supporting member 4 are inclined toward each other at an acute angle.
  • the lateral surfaces 12 are inclined away from the running surface of the web member 1 and are plane over their entire height and length so that in any state of wear approximately the same conditions are obtained with regard to gripping the road.
  • the distance between the lateral surfaces 12 is so selected that within the range of the lateral surfaces 8 of the link body 2 they protrude beyond the link member 2'in such a way that the supporting member 4 within the range of the link body 2 partially has a greater width than the thickness of the link body 2-and has a high wear-resistance at low weight, and small dimensions of the link will be assured.
  • the bottom surface 13 of the supporting member 4 is formed by two individual surfaces 14 which have the same size and form an acute angle with each other in a rooflike manner.
  • the line of intersection of said inclined surfaces 14 is located inthecentral longitudinal plane 6 of the web member 1 so that a rounding of the bottom running surfaces in view of wear can even be better avoided.
  • the web member which is arranged ona tire protective chain in a kindof netlike manneror the like has in view of its relatively inaccurate connection with the adjacent link members a so-called tilting play which makes it possible for the web member to assume two tilting positions which are oppositely inclined with regard to the driving plane. These two tilting positions are possible under the influence of the. axle pressure to be absorbedthereby and pertaining to the-motor vehicle so that the web member, i.e.
  • the individual surfaces when contactingthe road, will not be completely perpendicular to the plane of theroad' but will be slightly inclined relative thereto. If now the individual surfaces are inclined at an angle corresponding to the tilting positions of the bottom runningsurface, in each of the two tilting positions of the web member one individual plane of the bottom running surface will be parallel to the plane of the road so that this individual surface will substantially over its entire surface have contact with the road and therefore will wear uniformly.
  • the individual surfaces which are inclined relative to each other at an angle of approximately 170 are symmetrical to the longitudinal central plane of the link whereby for both tilting positions of the web member equal conditions are present and a special'arrangement of the web memberfor the assembly is not required.
  • the individual surfaces 14 are located relative to the adjacent surface 12 of the supporting member 4 at an angle of slightly less than so that the supporting member 4 will have sharp side edges 16.
  • the intermediate supporting member 4 has a trapezoidal shape because its plane. end surfaces 17 extend relative to thebottom surface 13 at an acute angle so that the magnitude of the bottom running surfaces will be only immaterially changed in view of the wear of the intermediate supporting member.
  • the end faces l'7'thus together with the bottom running surface 14 form obtuse angled edges 18.
  • the distance of the intermediate supporting member 4 with regard to the adjacent supporting member 3 amounts to more than half of the longitudinal extension of the intermediate supporting member 4.
  • the tire engaging surface 19 of the web member 1 which faces'away from the running surface is in order to save the tire formed by a broadened portion 20 of the link body 2 which'broadened portion extends approximately over the entire length of the link.
  • the broadened portion 20 has semicircularly rounded lateral surfaces 21 while the tire-engaging surface 19 is. plane.
  • the broadened portion 20 of the link body 2 is slightly wider than the intermediate supporting member 4 at its widest portion so that too large tilting movements of the link body will be avoided.
  • two oblong chain link openings 23 which within the area. of their passage through the lateral surfaces 8 of the link body 2 have their diameter rounded and widened.
  • the magnitude of the openings 23 is with regard to the chain portions to be suspended therein and pertaining to a tire protective chain so selectedthat the web member 1 will be able to tilt in both possible directions perpendicular to its central plane 6 to such an extent that always one of the individual surfaces 14 pertaining to the running surface 13 will be parallel to the ground or driving road when contact with the bottom is established.
  • the end faces 9 of the link body 2 merge through strong quarter circle roundings 24 with the tire installation surface 19.
  • I members 3a are arranged symmetrically with regard to the transverse plane 70.
  • the lateral surfaces 12a of all supporting members 3a, 4a are inclined toward each other andwith regard to the bottom running surfaces 11a, 130 at an angle of 90 while the running surfaces 1 la, 13a of all of the supporting members 311, 4a are located in a common plane for reducing the surface pressure.
  • the end faces 17a of the intermediate supporting members 40 are inclined with regard to the bottom running surfaces 13a at an acute angle and toward each other.
  • Those end faces a of the outer supporting members 30 which are located opposite the end faces 170 are inclined with regard to the running surface of the web member and away from the end faces 17a at an acute angle.
  • the outer end faces 1% of the outer web members 30' are formed by rounded portions 10b rounded over a quarter ofa circle.
  • the web member according to the invention will even after the supporting members have worn, still have a relatively good grip because in this instance the bottom running surface together with the lateral surfaces forms sharp edges.
  • the tire engaging surface 190 is according to the cross section of FIG.
  • the rounded areas 27 are also provided at the merging areas between the end faces 90 and the lateral surfaces 8 0. These rounded areas 27 are guided by the outer supporting members 30 into the rounded the engaging surfaces 19a.
  • the lateral surfaces of the separating web 28 which pertains to the link body 2a and is located between the chain link openings 23a are arranged in the plane of the respective associated lateral surface 80 of the link body so that the lateral surfaces of the separating web 28 likewise gradually merge with the tire-engaging surface 19a.
  • the web member according to the embodiment of FIGS. 3--5 has a good gripping effect and lateral stability when being employed on soft roads or the like.
  • a weblike traction member adapted for use in a tire chain and comprising: a weblike body which is apertured to receive connecting links of the chain so the body is supported in such a manner than it is presented edgewise to a roadway when the chain is mounted on a tire, said body on its roadway-engaging side having support portions protruding therefrom and spaced along the body in the longitudinal direction thereof, and at least one intermediate support member protruding from the said roadway-engaging side of said body and having lateral surfaces which are inclined toward each other in a direction away from said road-engaging side ofsaid body.
