A drawbar unit for a drawbar governed floor conveyor, in which a drawbar head is coupled to a vertical steering shaft, which optionally co-operates with a swiveling angle transmitter for an electronic steeling of the floor conveyor, wherein the steering shaft can be rotatably and axially fixedly mounted in a stationary bearing arrangement of the floor conveyor, wherein the drawbar head is connected to the upper end of a longitudinal guiding member, on which an upper portion of the steering shaft is axially guided, a lever is pivotably mounted on the guiding member, which engages with one arm into an axis parallel guiding channel on the steeling shaft such that a rotary union is produced, and an adjustment means mechanism acts on the lever in order to selectively bring the arm into clamping engagement with the steering shaft and to couple guiding member and steering shaft even axially.
