Abstract:
1. A telescopic shaft for transmitting torques, comprising: an inner profile tube, an intermediate profile tube and an outer profile tube, the inner, intermediate and outer profile tubes are displaceably arranged with respect to each other for length adjustment; a connection element includes at least one axial elongated opening for coupling with the inner profile tube for transmitting torque, the connection element is axially non-displaceably held inside the intermediate profile tube and coupled with the intermediate profile tube for transmitting torque, and the connection element is axially displaceable inside of the inner profile tube; an engagement mechanism is connected to the inner profile tube, the engagement mechanism engages the at least one axial elongated opening of the connection element to limit a displacement path between the inner profile tube and the connection element and to transmit torque between the connecting element and inner profile tube, and the outer profile tube is coupled with the intermediate profile tube for torque transmission.
