Abstract
The invention relates to an infinitely variable friction gear with several frictional wheels which are to transmit via the driving power. The frictional wheels are rotationally mounted in combined axial-radial-bearings (), which comprises split bearings () which are inserted into the supports () for the friction wheels () and which are rotated at an pivoting axis angle (α) in relation to angle Y. The opposite-lying supports of each gear unit are connected to each other by an upper coupling rod () and a lower coupling coupling rod ().
