Hydraulische Handpumpe, insbesondere zum Kippen von FahrzeugkabinenHydraulic hand pump, especially for tilting vehicle cabins

BESCHREIBUNGDESCRIPTION

Die Erfindung betrifft eine Handpumpe gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a hand pump according to the preamble of the main claim.

Solche Handpumpen sind ein einer Vielzahl von Ausführungsformen bekannt. Die wichtigsten Bauteile sind Betätigungselemente, Zylinder und Kolben, Saug- und Druckventil, Überdruckventil sowie ein Wegeventil zur Steuerung des Hydraulikzylinders, angeordnet in einem Gehäuse, das auch als Ölbehälter dient.Such hand pumps are known in a variety of designs. The most important components are actuating elements, cylinders and pistons, suction and pressure valves, pressure relief valves and a directional valve for controlling the hydraulic cylinder, arranged in a housing that also serves as an oil tank.

An diese Baueinheit werden Anforderungen an Größe, Gewicht, Preisgünstigkeit und an Zugänglichkeit in Verbindung mit engen räumlichen Verhältnissen im Fahrzeug gestellt.This unit has to meet requirements in terms of size, weight, affordability and accessibility in conjunction with the limited space available in the vehicle.

Der Erfindung liegt die Aufgabe zugrunde, durch Anordnung der Komponenten zueinander und Reduzierung der Anzahl der Teile eine optimale Lösung der Forderungen zu finden.The invention is based on the task of finding an optimal solution to the requirements by arranging the components in relation to one another and reducing the number of parts.

Bevorzugte Ausfuhrungsbeispiele werden nachfolgend erläutert:Preferred examples are explained below:

Figur 1 Handpumpe in schematischem Querschnitt in horizontaler AnordnungFigure 1 Hand pump in schematic cross section in horizontal arrangement

Figur 2 Einen schematischen Schnitt durch das VentilelementFigure 2 A schematic section through the valve element

Figur 3 Handpumpe in schematischem Querschnitt in vertikaler AnordnungFigure 3 Hand pump in schematic cross section in vertical arrangement

Beschreibung zu Figur 1Description of Figure 1

Im Gehäuse (1) ist integriert Zylinder (2). Dieser Zylinder gehört zu Kolben (3) und Ventilelement (4).Cylinder (2) is integrated into the housing (1). This cylinder belongs to the piston (3) and valve element (4).

Das Ventilelement ist drehbar mittels Hebel (5). Die Betätigung des Kolbens erfolgt über Hebel (6).The valve element can be rotated using a lever (5). The piston is actuated using a lever (6).

Das Gehäuse ist Ölbehälter. Das Öl wird gefüllt über Einfüllbohrung (7). Der Ölstand ergibt sich durch die Lage der Bohrung (8). Das Ansaugen geschieht über Bohrungen und Filter (9) und (10). Alle Funktionen sind in einem einzigen Gehäuse integriert. Verschlossen wird das Ganze über mindesten einen, hier nicht dargestellten Deckel.The housing is an oil container. The oil is filled via the filling hole (7). The oil level is determined by the position of the hole (8). The suction takes place via holes and filters (9) and (10). All functions are integrated in a single housing. The whole thing is closed with at least one cover, not shown here.

Dieser Deckel kann auch die Lagerung für die Antriebswelle des Hebels (6) tragen.This cover can also support the bearing for the drive shaft of the lever (6).

Beschreibung zu Figur 2Description of Figure 2

Das Ventilelement (4) beinhaltet Druckventil (11), Saugventil (12), Überdruckventil (13) und Hebel (5).
Die Ventile können auch als Einheit im Ventilelement, dessen Hauptfunktion die Steuerung eines Hydraulik-Zylinders ist, integriert sein.The valve element (4) includes pressure valve (11), suction valve (12), pressure relief valve (13) and lever (5).
The valves can also be integrated as a unit in the valve element, whose main function is to control a hydraulic cylinder.

Über die Bohrung (14) und das Dichtelement (15) wird eine druckdichte Verbindung zu den Räumen eines Hydraulikzylinders hergestellt. Durch Drehen des Ventilelementes z.B. über den Hebel (5) wird Verbindung zu den Zylinderräumen hergestellt und die Bewegungsrichtung des Zylinders bestimmt.A pressure-tight connection to the chambers of a hydraulic cylinder is established via the bore (14) and the sealing element (15). By turning the valve element, e.g. via the lever (5), a connection to the cylinder chambers is established and the direction of movement of the cylinder is determined.

Beschreibung zu Figur 3Description of Figure 3

Der schematische Querschnitt zeigt eine Anordnung in vertikaler Anordnung. Im Gehäuse (1) ist eine Zylinder-Ventileinheit (16) angeordnet. In dieser, um die Achse des Kolbens (3) drehbaren Einheit, finden sich Kolben und Ventile, somit für sich eine vollständige, vormontierbare Einheit.The schematic cross-section shows a vertical arrangement. A cylinder valve unit (16) is arranged in the housing (1). This unit, which can be rotated around the axis of the piston (3), contains pistons and valves, thus forming a complete, pre-assembled unit.

In dieser Darstellung sind die Ventile (12), (13), (14) in einem Körper zusammengefaßt und konzentrisch zur Achse des Kolbens montiert und druckdicht befestigt.In this illustration, the valves (12), (13), (14) are combined in one body and mounted concentrically to the axis of the piston and secured in a pressure-tight manner.
