ABSTRACT:
Belt for a continuous variable transmission, comprises an endless carrier for taking up tensile forces, and a plurality of transverse elements moveable in the longitudinal direction along the carrier. The elements are provided with at least one saddle surface for contacting the carrier. The saddle surface defines an ultimate mutual position of the carrier and the elements relative to each other within the belt in radial direction, with a tapered lower part including a rocking edge and an upper part extending radially above the edge and beyond the carrier, when the carrier and surface are in mutual contact. A thickness of the upper part of a majority of the elements in the longitudinal direction is larger than a largest thickness of the tapered lower part, such that an array of elements pushed against one another within the belt when mutually contacting through their upper parts assumes an arc-like shape.
