Title
(EN) MULTI-RIBBED CVT BELT
(FR) COURROIE DE TRANSMISSION VARIABLE EN CONTINU A CANNELURES MULTIPLES
Abstract
(EN)
The invention comprises a plurality of clips (10) arranged about a tensile member (20) or core belt. The tensile member comprises a multi-ribbed belt. The multi-ribbed belt may comprise any standard multi-ribbed belt readily available in the art. The clips are generally u-shaped and have opposing inclined sides that cooperate with the sides of a CVT pulley. The opposing inclined sides of each clip can have a thermoset, thermoplastic or phenolic coating to provide a predetermined coefficient of friction. Each clip has a multi-ribbed profile bearing surface that cooperates with the multi-ribbed portion of the core belt. The clips are held in proper orientation to the multi-ribbed belt by elastomeric bands (22, 31). The elastomeric bands are routed through a slot (11, 18) in each clip which then compresses the clips together.
(FR)
La présente invention concerne une pluralité de brides (10) agencées autour d'un élément de traction (20) ou d'un filin. Cet élément de traction comprend une courroie à cannelures multiples. Cette courroie à cannelures multiples peut consister en n'importe quelle courroie à cannelures multiples immédiatement disponible sur le marché. Ces brides sont généralement en forme de U et présentent des côtés opposés inclinés qui coopèrent avec une poulie de transmission variable en continu. Les côtés opposés inclinés de chaque bride peuvent posséder un revêtement thermodurci, thermoplastique ou phénolique de façon à offrir un coefficient de frottement prédéterminé. Chaque bride possède une surface de support à profil à cannelures multiples qui coopère avec la partie à cannelures multiples du filin. Les brides sont tenues dans l'orientation correcte sur la courroie à cannelures multiples par des bandes élastomères (22, 31). Ces bandes élastomères sont guidées à travers une fente (11,18) dans chaque bride, ce qui comprime ensuite les brides entre elles.
