Abstract

A continuously variable transmission 1 has two saucer-shaped pulley parts (3, 5) that are connected to each other. One of the pulley parts (3) is a disc (7) that is fastened to a first input/output shaft (9) and is provided with an upright peripheral wall (11). The other pulley part (5) is a fixed ring (13) in the upright peripheral wall that can move axially and radially with respect to the disc (7). The saucer-shaped disc (7), and the ring (13) are situated with their concave sides facing each other. Furthermore, the continuously variable transmission (1) has a disc (15) made from one piece that is provided with a dovetail-shaped peripheral groove (17) in which are found the dovetail-shaped coupling parts (21) of the shift elements (19) that are coupled together and situated one behind the other in a ring round the disc. The disc (13) is connected to a second input/output shaft (23) and is situated between the two pulley parts (3, 5). Here a number of the shift elements (19) touch the pulley parts (3, 5) with their side surfaces (25).
