Link belt for continuously variable cone-pulley transmissions

摘要

The invention relates to a link belt for continuously variable cone-pulley transmissions, the said belt comprising a multiplicity of trapezoidal plate elements which follow one another closely and, in the region of their narrower trapezium base, are provided with an oblique flat and are held together in contact with one another by tensile elements to form an endless drive belt. A multiplicity of joint pins extending in the direction of tension of the drive belt, arranged midway up the trapezium and in each case connecting two adjacent plate elements are arranged pairwise as tensile elements, the pairs of joint pins being arranged alternately on the inside and on the outside of successive plate elements, the contact surface (21) satisfies a convex cosine function at the transition from the zero line (M1-M2) to the flat (24). <IMAGE>
