  • the fiber composite material is preferably made of laminates in the form of carbon fiber material.
  • the rigid foam which is particularly resistant to tension and compression, consists for example of PUR, PP, acrylic, acrylate.
  • a fiber-reinforced rigid foam can be used, which has, for example, glass fibers, carbon fibers, aramid fibers, etc.
  • the central hub element (star element) has on its outer circumference a star-shaped structure or a tooth structure with which the foam core (s) are in operative connection.
  • Such wheel rims are used in particular for sporty cars and sports cars or in racing.

Abstract

L'invention concerne un système de jante comprenant un obturateur central comprenant une jante de roue, qui comprend un premier rebord de jante avant et un deuxième rebord de jante arrière pointant vers le véhicule, ainsi qu'un lit de jante s'étendant entre les deux, ainsi qu'une étoile de jante comprenant plusieurs rayons ou un disque de jante ainsi que des moyens pour une réception centrale sur un véhicule, situés sur le diamètre interne de l'étoile de jante ou du disque de jante, la jante de roue selon l'invention étant réalisée en construction hybride et des moyens pour la réception centrale de la jante de roue sur un véhicule étant réalisés sur l'élément de moyeu métallique ou la jante de roue pouvant être connectée au véhicule au moyen d'un élément adaptateur pouvant être mis en liaison active avec l'élément de moyeu métallique, un système de sécurisation pour la jante de roue étant au besoin présent, au moyen duquel un écrou central qui est vissé sur un filetage extérieur d'une réception de jante de l'élément adaptateur est sécurisé contre la perte et/ou l'élément adaptateur étant au besoin réalisé sous la forme d'un élément adaptateur de refroidissement comprenant un dispositif de refroidissement. L'invention concerne en outre un élément adaptateur et un système de sécurisation pour le système de jante.
