Abstract
Description
Die Erfindung betrifft einen Horizontalregler, der bei Fahrtransporten im unebenen Gelände und in Schräglagen den Tragrahmen für die Last stets waagrecht stellt. Dies bringt Vorteile für den Energieverbrauch und die Kippstabilität des Gefährts, sorgt für eine gleichmäßigere Verteilung der Achslast und fuhrt zu einem besser verteilten, optimal schonenden Bodendruck.The invention relates to a horizontal controller, which is used in road transport uneven terrain and in inclined positions, the support frame for the load always horizontal. This brings advantages for energy consumption and the Tilt stability of the vehicle ensures a more even distribution of the Axle load and leads to a better distributed, optimally gentle Ground pressure.
Ein mit Halteplatte 19 mit Haltebogen 16 und mit Kreuzgelenk 15 am Tragrahmen 4 angebrachter, der Schwerkraft unterliegender Pendelschalter 14 mit elektrischer Umschaltung steuert einen zwischen Achse 8 und Tragrahmen 4 befindlichen Hydraulikzylinder 3 derart, daß bei Auf- und Abwärtsbewegung der Räder 1 und 2 die waagrechte Position des Tragrahmens 4 stets wieder hergestellt wird. Weitere Aufgaben werden durch die beschriebenen Merkmale der Patentansprüche gelöst.A with a mounting plate 19 with a mounting bracket 16 and a universal joint 15 attached to the support frame 4 , the gravity-dependent pendulum switch 14 with electrical switch controls a hydraulic cylinder 3 located between the axis 8 and the support frame 4 in such a way that when wheels 1 and 2 move up and down the horizontal Position of the support frame 4 is always restored. Further tasks are solved by the described features of the claims.

Der Hydraulikzylinder 3 drückt den Tragrahmen in Richtung waagrechte Lage. Zwischen den beiden Kolben 6 und 6a befindet sich ein Stromunterbrecher, wodurch jetzt der Strom wieder unterbrochen wird. Die Feder 11 drückt den Kolben 6 mit leichter Verzögerung, gebremst durch eine als Ölbremse fungierende Kolbenbohrung mit Federklappe, in die Sperrstellung zurück. Das Heben des Tragrahmens bis zur Unterbrechung des Hydraulikzylinders 3 wird solange wiederholt bis eine waagrechte Position erreicht ist und der Strom durch den Pendelschalter 14 abgestellt wird. Dieser Vorgang läuft schneller ab als das Heben des Rades.
Der analoge Regelungsvorgang spielt sich beim Heben von Rad 1 ab. Beim Fahren auf der Straße oder im ebenen Gelände kann der Regelmechanismus durch Abschalten des Stromes stillgelegt werden.Horizontal controller for maintaining a horizontal position of the support frame of transport vehicles when traveling over uneven ground and in inclined positions, characterized in that the load on the support frame 4 is always kept in a horizontal position by the cooperation between the pendulum switch 14 with electrical switchover and hydraulic cylinder 3 . Hydraulic cylinder 3 is attached to the support frame 4 with bolts 13 and on the axis 8 with bolts 12 . Brake piece 20 , fitting tube 22 , reinforcement 23 , adjusting screw 24 and locking nut 21 serve to brake the hydraulic cylinder 3 . The bearing pin 9 allows the axis 8 to be pivoted against the supporting frame 4 . A mounting plate 19 is attached to the supporting frame 4 , on which the pendulum switch 14 hangs on a universal joint 15 . The universal joint 15 has two functions. When there is an upward or downward gradient in the direction of travel of the vehicle, the retaining arch 16 fixed with the holding plate 19 follows the tilting movement, but does not produce any switching contact with the pendulum switch 14 . However, if the support frame 4 rises or falls transversely to the direction of travel, the pendulum switch 14 with its two current sensors 17 and 18 , following gravity, will attempt to maintain a vertically hanging position and hit against the current-carrying, fixed retaining arch 16 . One of the two separate current sensors 17 or 18 thus becomes live and controls on the hydraulic cylinder 3 an adjustment of the support frame to a horizontal position, ie until the pendulum switch 14 has become contactless again. Ties 16 and current sensors 17 and 18 control an electrical switch consisting of two separate circuits. The housing 5 with tension coil 10 , spring 11 with piston 6 or 6 a shows the locked electrical circuit. If, for example, wheel 2 is raised, the supporting frame 4 is also lifted on this side, and current will flow at the pendulum switch 14 between the holding bow 16 and the current collector 17 upon contact. The tension spool 10 pulls the piston 6 , which thus opens the way tOr the pressure oil.
The hydraulic cylinder 3 presses the support frame in the horizontal position. There is a circuit breaker between the two pistons 6 and 6 a, whereby the current is now interrupted again. The spring 11 pushes the piston 6 back with a slight deceleration, braked by a piston bore acting as an oil brake with a spring flap, into the locked position. The lifting of the support frame until the hydraulic cylinder 3 is interrupted is repeated until a horizontal position is reached and the current is switched off by the pendulum switch 14 . This process is faster than lifting the wheel.
The analog control process takes place when lifting wheel 1 . When driving on the road or on level ground, the control mechanism can be shut down by switching off the power.
