A drive belt (3) includes an endless carrier (31) and a plurality of transverse members (32) of varying thickness, i.e. of varying dimension measured in the circumference direction “L” of the belt (3), which transverse members (32) are provided with a rocking edge (18) in the form an axially and radially extending section of a respective main body surface (38; 39) of the transverse member (32) that is convexly curved in radial direction. According to the invention, the design of such drive belt (3) can be improved, at least in terms of durability, by shaping the rocking edge (18) of the thinner transverse members (32) of such drive belt (3) according a larger radius of curvature in comparison with the radius of curvature of the rocking edge (18) of thicker transverse members (32) thereof.
Drive belt (3) with an endless carrier (31) and a number of consecutive transverse members (32) mounted slidable on the endless carrier (31), each provided with a front main body surface (39) and with a rear main body surface (38), where between the transverse member (32) extends in thickness direction and whereof at least one is provided with a convexly curved part (18), of which transverse members (32) at least two types having a mutually different dimension in the thickness direction are included in the drive belt (3), characterized in that a radius of curvature of the convexly curved part (18) of the type of transverse members (32′) having the largest dimension in the thickness direction is smaller than the radius of curvature of the convexly curved part (18) the type of transverse members (32″) having the smallest dimension in the thickness direction.
