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.
