CVT GEARBOX HAVING IMPROVED CONTROLLABILITY

摘要

The invention relates to a CVT gearbox, comprising a conical disc pair (2) having a stationary conical disc (20) and an axially moveable conical disc (21), at least one centrifugal force element (3) that is moveably arranged in the axially moveable conical disc (21), a support element (4) which is arranged on the axially moveable conical disc (21) and which is connected to a crankshaft (11), wherein the centrifugal force element (3) is arranged between the support element (4) and a rear wall (22) of the axially moveable conical disc (21), and axially displaceable inner sleeve (53) that is connected to the axially moveable conical disc (21), a positioning device (5) for adjusting a position of the axially moveable conical disc (21), wherein the positioning device (5) is connected to the inner sleeve (53), and a control unit (6) that is designed to actuate the positioning device (5) in order to displace the moveable conical disc (21) in the axial direction (X-X) by means of the inner sleeve (53), in order to achieve a transmission change at the conical disc pair (2).
