Abstract:
1. Push belt for a continuously variable transmission, which is particularly destined to be arranged around pulleys of the continuously variable transmission, wherein pulley sheaves are part of the pulleys, the pulley sheaves having contact surfaces, and which push belt comprises a number of transverse elements and ring-shaped carriers for carrying the transverse elements, wherein the transverse elements have carrying surfaces for supporting the carriers, wherein the transverse elements have retaining surfaces facing the carrying surfaces, wherein the position of the carriers is delimited in a radial direction of the push belt by the carrying surfaces at one side, and by the retaining surfaces at another side, and wherein the transverse elements have contact surfaces for engaging the contact surfaces of the pulley sheaves which are part of the pulleys of the continuously variable transmission, wherein the contact surfaces of the transverse elements are provided with a profile, wherein there are at least two types of transverse elements present in the push belt, wherein the profile on the contact surfaces of transverse elements of one type is different than the profile on the contact surfaces of transverse elements of another type, wherein the profiles on the contact surfaces of the transverse elements comprise the same pattern of alternating elevations and recesses, and wherein, in respect of at least a part of the total number of transverse elements, the patterns of elevations and recesses of adjacent transverse elements of a different type are shifted with respect to each other, in the radial direction.
