The block type CVT belt according to the present invention comprises at least one endless load carrier having tensile members. A plurality of blocks (20) are transversely engaged with the load carrier in a lengthwise direction of the belt. The center of gravity of each block is asymmetrically located in each block. Each block has termostet or thermoplastic over-molding. The over- molding is attached to the metal block (10) by use of an adhesive. The preparation of the metal reinforcing member is accomplished by mechanical tumbling means, as opposed to chemical preparation. Each block also comprises at least one slot for receiving the load carrier. Each slot having an upper concave surface (22) and a lower surface (23) having a complex shape. The upper concave surface receives a corresponding convex surface or tooth on an upper surface of the tensile member. Each slot is provided with a complex radius between a central pillar and an upper and lower arm in order to avoid stress risers. The load carriers are slightly compressed in each groove to significantly reduce skew.

Courroie de transmission variable continue (CVT) de type bloc comprenant au moins un support de charge sans fin possédant des éléments de traction. Une pluralité de blocs (20) est accouplée au support de charge dans un sens transversal sur la longueur de la courroie. Le centre de gravité de chaque bloc est situé de façon asymétrique dans chacun de ces blocs. Chaque bloc possède un surmoulage thermodurci ou thermoplastique. Ce surmoulage est fixé au bloc (20) de métal au moyen d'un adhésif. La préparation de l'élément de renforcement métallique s'effectue par des moyens de culbutage mécanique, contrairement à la préparation chimique. Chaque bloc comporte également une fente au moins servant à recevoir le support de charge. Chaque fente possède une surface supérieure (22) concave et une surface inférieure (23) de forme complexe. La surface supérieure concave reçoit une surface convexe ou une dent correspondante placée sur une surface supérieure de l'élément de traction. Chaque fente est pourvue d'un rayon complexe entre un pilier central et un bras supérieur et inférieur, de façon à éviter l'apparition de contraintes. Les supports de charge sont légèrement comprimés dans chaque rainure, de manière à limiter considérablement l'inclinaison.
