    On the pendulum double-axle unit (1) with mounted ball-bearing turntable (4), a double-frame construction (2) with stanchions or loading area is set up. The turntable (4) is screwed to the lower bearing area with the pendulum double-axis unit (1) and to the upper bearing area with the double-frame construction (2). The rotational movement of the slewing ring (4) is effected by means of two double-acting hydraulic cylinders (3) which are each articulated to the pendulum double-axle unit (1) and the double-frame construction (2). The double-acting hydraulic cylinders (3) are controlled by the tractor from a double-acting control unit, which is connected to hydraulic hoses with the double-acting hydraulic cylinders (3). A equipped with a return spring hydraulic cylinder (5) which engages in straight ahead without hydraulic pressure via a guide iron, which is fixed to the pendulum double unit (1), is attached to the double frame construction (2).

    Description OF THE PREFERRED EMBODIMENT: [0001] A double-frame construction (2) with stanchions or loading surface is set up on the pendulum double-axle unit (1) with mounted turntable (4). The slewing ring (4) is bolted to the lower support area with the pendulum double-axis unit (1) and to the upper support area with the double-frame construction (2). The rotational movement of the turntable (4) by means of two double-acting hydraulic cylinder (3) each on one side with bolts 30 ° on Pendel Doppelachsaggregat (1) and in each case on the opposite side with bolts 30 o on the Dop¬pelrahmenkonstruktion (2) are effected causes. The double-acting hydraulic cylinders (3) are controlled by the tractor from a double-acting control unit, which is connected to hydraulic hoses with the hydraulic cylinders. When the two hydraulic cylinders (3) are acted upon, a hydraulic cylinder (3) pulls in up to about 200 mm, the opposite hydraulic cylinder (3) extending by up to about 200 mm.
    A hydraulic cylinder (5) equipped with a return spring, which engages in the direction of travel without hydraulic pressure via a guide bar fixed to the pendulum double-axle unit (1), is fixed to the double-frame structure (2).
    The single FIGURE shows a schematic representation of the subject invention. REFERENCE LIST: BZ 1: Pendulum double axle unitBZ 2: Double frame constructionBZ 3: Double-acting hydraulic cylinderBZ 4: Slewing ring BZ 5: Hydraulic cylinder equipped with a return spring

    Claims (4)
    [1]
    Claims 1. Steering tractor trailer with central axis, eg rear wagons, gekenn¬zeichnet that on the Pendeldoppelachsaggregat (1) with attached ballgelagertem slewing ring (4), a double frame construction (2) is constructed with stanchions or loading area, wherein for producing a rotatable connection between Pendeldoppelachsaggre¬ gat (1) and double frame construction (2) of the turntable (4) is screwed to the lower bearing area with the pendulum double-axis unit (1) and at the upper bearing area with the double frame construction (2).
    [2]
    2. Steerable tractor trailer with central axle, e.g. Rear wagons, according to claim 1, characterized in that for a rotary movement of the steering function serving Drehzranzes (4) two double-acting hydraulic cylinders (3) are each hinged to the Pendeldoppelachsaggregat (1) and the double frame construction (2).
    [3]
    3. Steerable tractor trailer with central axle, e.g. Rear wagon, according to one of the preceding claims, characterized in that for controlling the two-double-acting hydraulic cylinder (3) a control device is provided on the towing vehicle, which is wirkver¬bunden via hydraulic hoses with the double-acting hydraulic cylinders (3).
    [4]
    4. Steerable tractor trailer with central axle, e.g. Rear wagon, according to one of the preceding claims, characterized in that a hydraulic cylinder equipped with a return spring and attached to the double frame construction (2) for determining straight ahead travel is equipped with a latching mechanism.
