Double-sided sliding button for use in a continuously variable transmission
The double-sided sliding button comprises two spaced-apart sliding button halves configured and disposed with reference to a curved medial axis. Each half has a front side, provided with a contact surface, and a rear side. Both contact surfaces are mutually opposite and both sides of each half intersect the curved medial axis. A bridge member allows to rigidly connect the rear side of the two halves. With this configuration, each sliding button can be easily installed and secured in a clamp attached to a part of the driven pulley. Each double-sided sliding button is capable of working in both directions, thereby reducing the number of individual sliding buttons to be installed by 50%.
