CA 2323264
The invention provides a disc brake backing plate with an integrally formed spring hole plug. A blind hole is defined within the plate, terminating at a closed boss (plug) on the friction material- receiving surface of the plate. The blind hole is adapted to receive and secure an end of a conventional shoe retaining spring for mounting the finished brake pad within a disc brake caliper. The integral boss prevents friction material from entering the hole at the friction molding stage, relieving the manufacturer of the need to add separate blocking hardware. A method of manufacturing the plate with an integrally formed spring hold plug is also provided.
L'invention concerne une flasque de frein à disque incorporant un bouchon à ressort. Un trou borgne est défini à l'intérieur de la flasque, se terminant à un bossage fermé (bouchon) sur la surface réceptrice du matériau de friction de la flasque. Le trou borgne est conçu pour recevoir et fixer une extrémité d'un ressort de retenue de patin conventionnel pour insérer la plaquette de frein finie dans un étrier de frein à disque. Le bossage intégral empêche l'entrée du matériau de friction au niveau du moulage de friction, ce qui libère le fabricant du besoin d'ajouter un matériel de blocage séparé. Est également présenté un procédé de fabrication de la flasque incorporant un bouchon à ressort.
