  • Rim shoulder and the wheel disc is housed. This was required by the introduction of disc brakes on commercial vehicles. Since the space was very limited in this area, a hump (bead) was introduced as a security element in the rim and the cylindrical seat on which the wheel disc is welded, in the direction Rim center shifts. These changes allowed a curved valve to be located in the protected area between the rim shoulder and the wheel disc.
  • the disadvantage of this construction is that the connecting weld lies in a critically stressed area of the rim. In order to ensure the required operational strength during driving, the rim thickness as well as the wheel disc thickness had to be manufactured in a reinforced version. In addition, the height of the wheel, due to the Humpab distren and the required overlap of rim and disc, very high. All these features mean that the weight of such wheels is significantly higher than it was before the introduction of the brake discs and the associated displacement of the valve.
  • Invention designed a weight-optimized Steilschulterrad for commercial vehicles with external valve with the aim of reducing feedstock, weight and cost.

Abstract

L'invention concerne une roue de véhicule utilitaire comportant une jante à bord oblique pour pneus sans chambre à air, et un corps de roue soudé au moyen d'un joint bout à bout dans l'arc de courbure de la base creuse (4) vers la paroi latérale (8a). Sur des roues à bord oblique, cette zone est la plus rigide de telle manière que des roues comportant une telle liaison jante/corps sont soumises aux sollicitations alternées les plus faibles en marche et présentent par conséquent une meilleure résistance à la fatigue. Le soudage n'est réalisé que depuis le côté intérieur. Ce soudage (11) est caractérisé en ce que la jante est pourvue d'une sécurité de bain de soudage (19) disposée de façon particulière permettant une liaison par soudage (11) très sûre de la jante (1) et du corps de roue (2). La modification de la position du cordon de soudure (11) permet diverses modifications de la jante, de la cuvette (2) et de la position (7) de la valve de telle manière qu'il est possible de réduire de 15 % la quantité de matière employée, ce qui entraîne une réduction de poids et de coût des roues. La disposition de la valve peut être choisie de telle manière qu'il est possible d'employer un tuyau droit (12) en tant que valve extérieure.
