Definitions

  • This invention relates to a wheel for a pneumatic tyre for use on a vehicle such as an automobile.
  • a typical wheel for a pneumatic tyre has a rim providing a well extending circumferentially around the wheel, the parts of the rim bounding the well axially providing bead seats to support the beads of a pneumatic tyre fitted to the wheel, and further providing bead retaining flanges extending from respective said bead seats away from the axis of the wheel.
  • one or both bead seats are formed with a raised rib which acts to hold the tyre bead on the bead seat even when the tyre is deflated.
  • These wheel rim constructions are commonly known as "safety rims”.
  • the vehicle may tend to tilt to that side of the vehicle on which the puncture occurs so that the wheel bearing the tyre which has been punctured also tilts in the same fashion thus greatly affecting the steering geometry of the vehicle, reducing steering control and allowing only minimum use, if any, of the braking system to bring the vehicle to a halt.

  • the flanges 10 and 6 naturally extend around the entire circumference of the wheel the flange 6 extending substantially radially from its bead seat and having its radially outer edge rolled over, away from the well, to provide a bead.
  • the flange 10 includes a first portion, for engagement with the respective tyre bead, which extends substantially radially outwardly from the inboard bead seat, a second portion, extending from said first portion and over which the flange, in axial section through the wheel, bends away from an imaginary plane passing through the well and perpendicular to the wheel axis, a third portion, extending from said second portion and in which the bead retaining flange extends at a greater angle relative to the wheel axis than the adjoining part of said second portion, and a fourth portion, formed by rolling the free edge of the flange over in a manner similar to the edge of the flange 10 over in a manner similar to the edge of the flange 6, which fourth portion is thus disposed further from the wheel axis than said second portion and, in axial section, curves arcuately away from said imaginary plane passing through the well and perpendicular to the wheel axis to provide a radially outwardly facing ground engaging surface 14 of

Abstract

La présente invention concerne une roue pour un pneumatique, destinée à être utilisé sur un véhicule, comprenant une jante comportant un puits, des sièges de talon et des brides de retenue de talon s'étendant à partir de ces sièges de talon respectifs à l'opposé de l'axe de roue. L'une desdites brides de retenue de talon comprend une première partie s'étendant sensiblement radialement à partir du siège de talon respectif jusqu'à une deuxième partie qui, dans la section axiale à travers la roue, s'incurve à l'opposé d'un plan imaginaire passant à travers le puits et perpendiculaire à l'axe de roue. Une troisième partie s'étend à partir de la deuxième partie et à un angle supérieur en relation à l'axe de roue par rapport à la partie adjacente de ladite deuxième partie, et une quatrième partie s'étend à partir de la partie radialement extérieure de ladite troisième partie et est disposée plus loin de l'axe de roue que ladite seconde partie. Ladite quatrième partie, en coupe axiale à travers la roue, s'incurve de manière arquée à l'opposé dudit plan imaginaire passant à travers le puits. Ladite quatrième partie fournit une surface de contact avec le sol orientée radialement vers l'extérieur qui est de plus grand diamètre d'environ au moins 6/8 èmes de pouce que l'autre bride de retenue de talon.
