Abstract

Die zum Abziehen und Einpressen von Lagern und Hülsen von Achslagern an Kraftfahrzeugen dienende hydraulische Abziehvor­ richtung besteht aus einem Arbeitszylinder (4) mit einem Arbeits­ kolben (6) und einer die Stirnwand (2) des Arbeitszylinders (4) durchragenden Kolbenstange (7). Der Arbeitszylinder (1) steht mit wenigstens einem Druckzylinder (12, 15) kleineren Durchmessers in Verbindung, dessen Druckkolben (30) durch eine Gewindespindel (31) betätigbar ist. Um einerseits eine möglichst geringe axiale Baulänge und andererseits einen maximalen Arbeitshub des Arbeitskolbens (6) zu erzielen, der wenigstens annähernd gleich groß ist wie der Druckhub des Druckkolbens (30), sind neben dem Arbeitszylinder (4) in Parallellage dazu wenigstens zwei Druckzylinder (12, 15), die unterschiedliche Durchmesser haben können, in der Wandung des Arbeitszylinders (4) angeordnet, die jeweils durch Druckmittelkanäle (18, 21) einer gemeinsamen Stirnwand (2) mit dem Arbeitszylinder (4) verbunden sind. The for pulling and pressing bearings and sleeves from Hydraulic puller for axle bearings on motor vehicles direction consists of a working cylinder (4) with a working piston (6) and the end wall (2) of the working cylinder (4) protruding piston rod (7). The working cylinder (1) is smaller with at least one pressure cylinder (12, 15) Diameter in connection, the pressure piston (30) through a threaded spindle (31) can be actuated. On the one hand axial length as small as possible and on the other hand a maximum Achieve working stroke of the working piston (6), at least is approximately the same size as the pressure stroke of the pressure piston (30) are next to the working cylinder (4) in parallel at least two printing cylinders (12, 15), the different Can have diameters in the wall of the working cylinder (4) arranged, each through pressure medium channels (18, 21) a common end wall (2) with the working cylinder (4) are connected.
