Abstract
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.
