Push belt for a continuously variable transmission, comprising different types of transverse elements

Abstract

A push belt () for a continuously variable transmission comprises transverse elements () of at least two different types, wherein the differences between the transverse elements () reside in a profile () which is present at pulley sheave contact surfaces () of the transverse elements (). On the basis of the use of at least two different types of transverse elements () as mentioned, many advantages are achieved, including improved traction, reduction of wear, and noise reduction. The design of the profile () can be such that a pattern of voids () is created at a contact side of the push belt (), which voids () are used for receiving oil. The pattern of voids () can be random, or not. In the latter case, it is possible to have a path () for discharging oil, extending along the contact side of the push belt ().
