Pneumatically adjustable continuously variable transmission

For a CVT comprising a cone pulley pair (2) having at least one axially movable cone pulley (21), an adjusting device (5) for adjusting a position of the axially movable cone pulley (21), and a control unit (6), which is designed to actuate the adjusting device (5) in order to vary the position of the axially movable cone pulley (21), wherein the adjusting device (5) comprises a pneumatic space (50), which is arranged on a rear side (22) of the axially movable cone pulley (21), with the result that a change in a pressure in the pneumatic space (50) brings about an axial movement of the axially movable cone pulley (21) in the axial direction (X-X), wherein centrifugal elements (3) are arranged on the axially movable cone pulley (21), wherein the pneumatic space (50) is defined by the rear side (22) of the axially movable cone pulley (21) and a front side (31) of a pulley housing (30), it is proposed that ramp-shaped supporting regions (32) are formed on the front side (31) of the pulley housing (30), wherein t
