The invention relates to a method for reinforcing the attachment of a crosspiece (14) onto an arm (12), said crosspiece having an axis (B) transverse to a twistably resilient axle (10). A transverse end section (30) of the crosspiece (14) ends in a free end edge (32). The free edge (32) comprises at least one first portion (36A, 36B), that is attached to one surface (17) of the longitudinal arm (12), and at least one second portion (38A, 38B), that is attached to the surface (17) of the arm (12). Said method is characterized in that it comprises, after attachment of the crosspiece (14) onto the longitudinal arm (12): - an operation for carrying out intense heating then rapid cooling of at least one area (40) of the crosspiece (14) wall that is located transversely and at a distance relative to the slightly biased portion (38A, 38B) of the free edge (32).

Un enjoliveur (4) comprend un disque (41) pourvu d'au moins une ouverture (43), adaptée à une circulation d'air apte à un refroidissement de pièces disposées au niveau d'une roue (3), et au moins une pièce thermofusible (42) d'occultation de ces ouvertures. Cette occultation empêche la circulation d'air à travers les ouvertures, et les pièces thermofusibles sont adaptées à se décomposer et à dégager ainsi les ouvertures au-delà d'une température critique, avantageusement de l'ordre de 100 °C. Cet enjoliveur permet d'éviter des endommagements en cas de surchauffe accidentelle. Roue et véhicule, en particulier véhicule automobile, munis d'un tel enjoliveur.
