beats. The piston 6 presses with the piston rod 7 This prevents the piston rod head 8 from catching the side flaps via the crank arm 5 when the amount is limited against the dead-center position, which prevents the hydraulic cylinder 4 from initially resisting the hydraulic cylinder swings back; opposed by this measure. 5 an excessive shock load is excluded. As a result of the reaction force of the hydraulic cylinder in the unloading position, the side flaps 2 of FIG. 4 are held around its pivot point 12 by the hydraulic cylinder 4, the oil of which is pivoted downwards until it is blocked with its inlet or outlet. If the side impact 11 α is to be closed again on the downwardly directed surface of the flap, the stop 15 is applied. In this way, the rod side of the piston 6, acted upon by pressure, receives the abutment 13 mounted by means of the lever 11 so that the locking shaft 1 rotates. If a rotary hydraulic cylinder is a fixed support. At the same time, an angle of about 10 ° is reached before the end position, so the locking pawl 17 through the pull rod 19 touches the bolt 9 the guide lever 24, pushes the system on the piston rod head 8 withdrawn. By means of the coupling 22, the stop lever 20 can now be locked in its locking position against the abutment 15 and, before the locking-assisted, pressurized hydraulic cylinder 4 reaches the dead center position, it locks the shaft 1 in the "open" direction . After renden lever 11 free. The hydraulic cylinder 4 can now fully retract with a small rotational path of the locking shaft 1 and the locking device 11 is locked by the stop lever 20, guide it over the dead center position, so that the side of the latter closes completely through the 2 flaps with the guide lever 24. The safety-bound coupling 22 when the crank pawl 17 is pivoted is rotated accordingly with the lever arm 5 pivoting back (FIG. 2). 11 withdrawn to the holding position.

with one in one with the bearing point of 20. The invention is explained in more detail on the basis of a fixed embodiment shown in each drawing, which corresponds to the securing pawl (17), point (16) mounted on the carriage guide lever. It shows (24) is connected, the stop (lla) Fig. 1 parts of the locking device at gcschlos- of the lever (11) in the safety position and in the actuated side flaps viewed in the longitudinal direction of the car situation with different vehicle fixed 25 in view and Stops, the locking pawl (17) in see Fig. 2 in the same representation the locking position with the head (8) of the hydraulic cylinder with the side flaps open,
cylinder piston (6) and the guide lever (24) in the direction running in the longitudinal direction of the carriage. Securing position, at the beginning of the actuation and final wave 1 of a semi-trailer bulk wagon are the towards the end of the closing process with the joint 30 side flaps 2 hinged by means of handlebars 3, steering pin (26) between the crank arm (5) and The locking shaft 1 is actuated by the hydraulic cylinder piston (6) together a hydraulic cylinder 4, which is connected to the Verken. ■ end shaft 1 firmly connected crank arm 5 engages. In the hydraulic cylinder 4, the piston 6 is mounted, 35 whose piston rod 7 at the free end has a straight surfaces 8 α provided head 8 carries which is rotatably connected to the crank arm 5 by means of a bolt 9. The bolt 9 protrudes from the head 8 The invention relates to a closure device a little further. The hydraulic cylinder 4 For semi-trailer bulk goods wagons with actuation of the locking shaft, the locking shaft is operated by means of an eye 10 in a lever 11 Via crank arms by hydraulic cylinders, which are rotated around a pivot point 12 on a barbarrel of the linkage and automatically acting mechager 13 is pivotably mounted. The abutment 13 is Nischer security device against unintentional attached to a carrier 14 of the wagon and with open the side flaps .. a stop 15 is provided against which the handle Semitrailer bulk goods wagons are known in which 45 can create at 11. A securing pawl device which can be pivoted in one of the side flaps attached to the wagon when the hydraulic fixed point 16 is actuated without an intermediate position from the 17 can move with its straight surface 17 α to the closed into the fully open state. Place the straight surface 8 a of the piston rod head 8. In this case, a locking device is attached, at a pivot point 18 of the lever 11 a pull of a pre-unlocking is articulated by an elongated hole rod 19, which is the connection between the stroke. With this device, the sides may making the lever 11 and the securing pawl 17, tenklappen not actuated such that they α and the long hole 19 by means of pin 19 carried b ge-amount limiting be unloaded good. is articulated. A stop lever 20 is in this known device can not intercept a pivot point 21 articulated on the carrier 14 positions of the side flaps, since the subsequent 55 and by a load in a joint 20 α on the slipping load when suddenly stopping the hammer 20 and a Joint 23 on a Füh side flap causes a high impact load. lever 24 articulated coupling 22 with this The invention is therefore based on the object tied; The guide lever 24 is to be created in a rotating locking device, in which the point 16 a of the fixed point 16 on the wagon body is supported idle stroke for pre-unlocking the safety pawl 60 and is temporarily locked with the bolt 9 by the hydraulic cylinder and thus a form-fitting connection (Fig. 1). The stop, the side flaps in every intermediate position without lever 20 and the safety pawl 17 are connected to one another by the large impact load from the closed to the full spring linkage 25. The lig open state can be kept. Spring linkage 25 is in the pivot points 20 α or * As a solution to this problem, 65 17 b is articulated according to the invention. It is provided that the hydraulic cylinder of each device works as follows: device on its abutment via a with an To open the side flaps 2, the piston stroke provided lever is articulated, which is pressurized via one side of the hydraulic cylinder 4.
