Contact pressure control device for link chain of infinitely variable change speed gear for motor vehicles has transmission device to apply contact pressure, of length-adjustable levers connected to drive and driven transmission elements

摘要

The device has drive pulley and driven pulley pairings, with one travel pulley of a pairing being axially adjustable. A transmission device in the drive train consists of two or more levers (32), which are connected to the driving transmission element (52) and the driven transmission element (20,26). Each lever acts via roller elements (58) on an axially moveable transmission element (36), which applies direct or indirect contact pressure. Lever length required for contact pressure is dependent upon the set travel pulley position.
