Abstract: Drive belt (3) including several hundred transverse elements (20) provided on and in sliding relationship with an endless carrier (10) and having a head part (21) that is bent such that it protrudes in longitudinal direction relative to a body part (23) of the elements (20). On average between the transverse elements (20) of the drive belt (3), the longitudinal protrusion LP of the head parts (21) thereof combines to between 4 and 40 times an amount of play present in longitudinal direction between the transverse elements (20) of the drive belt (3) when placed in a circular posture at the radial position of the rocking edges (25).

Abstract: Adjustable pulley (7), in particular for a continuously variable transmission, with a pair of pulley sheaves (9), whereof a first pulley sheave (9) is attached to a pulley shaft (6) of the adjustable pulley (7) and whereof a second pulley sheave (8) is attached to a sleeve (25) of the pulley shaft (6) that is axially displaceable relative to such shaft (6). The adjustable pulley (7) being provided with a conically shaped coil spring (101) that is placed between the second, displaceable pulley sheave (8) and the pulley shaft (6) or a component (26) of the adjustable pulley (7) that is fixed to such shaft (6).

Abstract: A drive belt for continuously variable transmission for motor vehicles is provided with two pulleys, each including two substantially conical pulley sheaves, between which the drive belt can be held at a variable radial position, which drive belt is provided with transverse elements (32), which on both lateral sides are provided with a flank (40) that is intended for frictional contact with the pulleys, and which, at least in its height direction, i.e. radially relative to the pulleys (1, 2), is provided with a convex curvature, in which flank (40) one or more grooves (41) are provided.
