Continuously-variable-ratio transmission belt

摘要

A continuously-variable-ratio transmission belt (1) includes a beltlike continuity element (2) having a body (5) made of elastomeric material and in turn having inner teeth (6) and outer teeth (7) and a number of threadlike longitudinal inserts (8) embedded inside the body (5); and a number of separate friction blocks (3) which are made of plastic material, are co-molded onto the continuity element (2) so as to each incorporate one tooth (10) of the inner teeth (6) and one tooth (12) of the outer teeth (7), and are each defined by two lateral surfaces (4) converging inwards of the belt (1) and cooperating with respective sides of a groove of a trapezoidal-grooved pulley. <IMAGE> <IMAGE>
