Description

Die Erfindung betrifft eine Hebevorrichtung für Fahrzeuge, die durch ein seitlich vorstehendes Huborgan der Hebevorrichtung angehoben werden. Das Huborgan ist am unteren Ende einer Schraubenspindel angebracht; die durch Drehen einer in axialer Richtung nicht verschiebbaren, am oberen Ende des Hebers angeordneten Spindelmutter gehoben und gesenkt wird. Diese Heber zeichnen sich dadurch aus, daß die Spindel beim Heben nicht auf Knicken, sondern auf Zug beansprucht wird.The invention relates to a lifting device for vehicles by a laterally protruding lifting device of the lifting device can be raised. The lifting device is attached to the lower end of a screw spindle; which by turning one in axially non-displaceable, arranged at the upper end of the lifter spindle nut is raised and lowered. These jacks are characterized by the fact that the spindle when lifting is not subjected to buckling, but rather to tension.

Wird das seitlich vorstehende Huborgan mit der Schraubenspindel starr verbunden, so kann das Fahrzeug bei starkem Gefälle, Glatteis, oder bei zu schrägem Ansetzen der Hebevorrichtung, nach der gehobenen Seite kippen.If the laterally protruding lifting element with the screw spindle becomes rigid connected, the vehicle can be used on steep slopes, black ice, or on slopes that are too sloping Apply the lifting device, tilt it on the raised side.

Um das zu verhindern, wird erfindungsgemäß das seitlich vorstehende Huborgan mit dem unteren Ende der Schraubenspindel mit einem in der Längsachse .der Schraubenspindel angreifenden Kugelgelenk allseitig beweglich verbunden.In order to prevent this, according to the invention the laterally protruding Lifting element with the lower end of the screw spindle with a .der in the longitudinal axis Ball joint attacking the screw spindle connected to be movable on all sides.

Dadurch, daß das Kugelgelenk in der Spindelachse angreift, können in der Hebevorrichtung während des Hebevorganges keine Spannungen auftreten.The fact that the ball joint engages in the spindle axis can no tension occurs in the lifting device during the lifting process.

In der Zeichnung ist ein Ausführungsbeispiel der Hebevorrichtung dargestellt.In the drawing, an embodiment of the lifting device is shown.

Abb. i zeigt einen senkrechten Schnitt durch die Hebevorrichtung, Abb. 2 eine Ansicht von vorn und Abb. 3 eine Teilansicht der Vorrichtung.Fig. I shows a vertical section through the lifting device, Fig. 2 is a front view and Fig. 3 is a partial view of the device.

Ein kräftiger zylindrischer Schaft 7 mit einem Fuß ist von unten in eine Hülse 4 eingesteckt. Dieser Schaft 7 hat zwei Bohrungen ii, während die Hülse 4 nur eine Bohrung hat, durch die ein Bolzen 6 gesteckt werden kann, und zwar wahlweise durch die untere oder die obere. der Bohrungen ii, so daß die Hül-,e entweder in die Stellung gemäß Abb. i oder Abb. 2 der Zeichnung kommt.A sturdy cylindrical shaft 7 with a foot is in from below a sleeve 4 inserted. This shaft 7 has two bores ii, while the sleeve 4 has only one hole through which a bolt 6 can be inserted, optionally through the lower or the upper. of the holes ii so that the sleeve, e either in the position according to Fig. i or Fig. 2 of the drawing comes.

Die das Gehäuse der Hebevorrichtung bildende Hülse 4 hat am oberen Ende eine Lagerung 13 für zwei Kegelräder i und io. Die Achse des Kegelrades io hat einen Vierkant zum Aufstecken einer Handkurbel. Die Nabe des Kegelrades i ist als Spindelmutter für die Schraubenspindel 2 ausgebildet. Am unteren Ende der Spindel 2 ist das Huborgan 3 mittels eines Kugelgelenkes 5 allseitig beweglich angelenkt. Für das Huborgan 3 ist in der Hülse 4 ein -Längsschlitz 9 vorgesehen, der. so breit ist, daß sich das Huborgan horizontal ausreichend verschwenken läßt.The sleeve 4 forming the housing of the lifting device has a bearing 13 for two bevel gears i and io at the upper end. The axis of the bevel gear io has a square for attaching a hand crank. The hub of the bevel gear i is designed as a spindle nut for the screw spindle 2. At the lower end of the spindle 2, the lifting element 3 is articulated to be movable on all sides by means of a ball joint 5. For the lifting member 3 a longitudinal slot 9 is provided in the sleeve 4, the. is so wide that the lifting element can be pivoted sufficiently horizontally.

Durch Drehen des Kegelrades io mittels der Handkurbel zieht die Spindelmutter des Kegelrades i die Spindel :2 nach oben, so daß die Spindel nie "auf Knicken beansprucht werden kann. Im Bedarfsfalle kann die schraubbare Höhe des Huborgans 3 dadurch verlängert werden, daß der Bolzen 6 gemäß Abb. 3 durch die obere Bohrung i i des Schaftes 7 hindurchgesteckt wird.The spindle nut is pulled by turning the bevel gear io with the hand crank of the bevel gear i the spindle: 2 upwards, so that the spindle is never "subject to buckling" can be. If necessary, the screwable height of the lifting member 3 can thereby be extended that the bolt 6 as shown in Fig. 3 through the upper bore i i of the shaft 7 is inserted through.
