The invention relates to a drive train () between a power take-off shaft () of a tractor unit () and the gearbox () of a trailer vehicle (), the drawbar of which is coupled in a bottom hitching arrangement to the hitch () of the tractor unit (), wherein the drive train () extends above the drawbar beam. Depending on the rotational speed and length of the propeller shaft, a long propeller shaft may result problems in revolution that is agitated and vibratory. The novel drive exhibits smooth running properties and allows for easy handling.

Drive train between the power take-off shaft of a tractor unit and the gearbox of a trailer vehicle

A torque transmitting telescopic shaft () has an inner profile tube (), an intermediate profile tube () and an outer profile tube. The tubes () are displaceably arranged with respect to each other for length adjustment. A connection element (), with at least one axial elongated hole (), is axially non-displaceably held in the intermediate profile tube (). An engagement mechanism () connects with the inner profile tube (). The engagement mechanism () engages the at least one axial elongated hole () of the connection element () to limit a displacement path between the inner profile tube () and the connection element ().
