Title
(EN) DRIVE BELT COMPRISING DIFFERENT TYPES OF TRANSVERSE MEMBERS FOR A CONTINUOUSLY VARIABLE TRANSMISSION
(FR) COURROIE D'ENTRAÎNEMENT COMPRENANT DIFFÉRENTS TYPES D'ÉLÉMENTS TRANSVERSAUX POUR UNE TRANSMISSION À VARIATION CONTINUE
Abstract
(EN)
The invention relates to a drive belt (3) including an endless carrier (31) and a plurality of transverse members (30) that are mounted on and arranged along the circumference of the carrier (31) in an essentially contiguous row. This type of drive belt (3) is well-known, in particular from its application in the friction-type belt-and-pulleys transmission. According to the invention, the efficiency of such a transmission is improved when not all transverse members (30) of the drive belt (3) take part in the frictional contact with the transmission pulleys (1, 2). This technical effect is realized, in accordance with the invention, by providing the drive belt (3) with two types of transverse members (30), whereof the second type is less wide than the first type.
(FR)
L'invention porte sur une courroie d'entraînement (3) qui comprend un support sans fin (31) et une pluralité d'éléments transversaux (30) qui sont montés sur le support (31) et disposés le long de la circonférence de ce support en une file sensiblement continue. Ce type de courroie d'entraînement (3) est bien connu, en particulier pour son application à la transmission par friction du type à courroie et poulies. Selon l'invention, le rendement d'une telle transmission est amélioré lorsque tous les éléments transversaux (30) de la courroie d'entraînement (3) ne participent pas au contact de frottement avec les poulies de transmission (1, 2). Selon l'invention, cet effet technique est réalisé par le fait que la courroie d'entraînement (3) est équipée de deux types d'éléments transversaux (30), dont le second type est moins large que le premier type.
