Abstract: A vibration damper includes a rebound, in particular a rebound spring. The vibration damper includes a piston which is formed on an axially movable piston rod and which separates two working chambers in a cylinder, the working chamber penetrated by the piston rod being closed off with a lid and containing the rebound. An out-stroke of the piston rod relative to the cylinder includes an idle-stroke which starts at a minimum out-stroke and in which the rebound does not counteract the piston rod movement, a working-stroke which ends at a maximum out-stroke and in which the rebound counteracts the piston rod movement, and a point of application at which the idle-stroke ends and the working-stroke begins. The vibration damper further includes an arrangement configured to adjust the point of application.

Abstract: The invention concerns a process and device for fitting wheel heads on a vehicle chassis. The chassis and wheel head are first brought into a reference position relative to one another. Wheel guide elements which have not yet been finally fitted are used to determine the securing positions for the reference position and secured.

Abstract: In a mounting arrangement for a torsion bar of a torsion bar vehicle wheel suspension wherein the torsion bar is mounted at its one end to a cross link of a vehicle wheel suspension the other end of the torsion bar is connected to a mounting shoe which is engaged with the vehicle chassis only by the torque forces transmitted through the torsion bar.

Abstract: A pressure relief valve for the working pressure of a servo-steering mechanism of a vehicle, with a pressure medium connection between a high pressure connection adapted to be placed under a working pressure and a zero connection adapted to be placed under a lower pressure, whose valve-adjusting member is retained in a normal rest position closing off the pressure medium connection during normal conditions by a control device operating as a function of an operating magnitude of the servo-steering mechanism and which upon exceeding a critical value of the operating magnitude is adapted to be displaced into a by-pass position more or less opening up the pressure medium connection; the control device thereby operates in dependence on the load of the servo-steering mechanism while the by-pass position is independent of the angle of rotation of the steering shaft of the servo-steering mechanism.

Abstract: A servo-steering mechanism for vehicles with a feedback of a load-dependent reaction moment onto the steering hand wheel by means of at least one reaction pressure cylinder connected with a working pressure chamber, in which a reaction pressure piston operating onto the steering hand wheel is adapted to be actuated in one direction of its piston axis by the working pressure and in the other direction of its piston axis is adapted to be supported at a support spring and is also adapted to come into abutment at a stop fixed relative to the reaction pressure cylinder, when the working pressure has been brought to a value corresponding to the prestress of the support spring; between its starting position with an unstressed support spring and its shut-off or turn-off position at the associated stop the reaction pressure piston thereby comes into additional abutment at least at one reducing spring counteracting the working pressure, whereby the reducing spring is adapted to be supported either directly or by way of

Abstract: A by-pass valve for servo-steering systems to turn off the working pressure in a cylinder chamber of a pressure medium cylinder, whose valve housing includes a valve connection adapted to be connected with the cylinder chamber, a valve connection adapted to be essentially pressure-relieved, and a valve seat for a check valve operatively connected between the two valve connections; the valve housing is thereby adjustable relative to the axis of a steering shaft for purposes of changing the position of its valve seat while the closure member of the check valve is thereby retained by springy means in its normal position closing-off the valve connections with respect to one another and is actuatable into its by-pass position connecting the valve connections with each other by way of a stem movable in unison with the closure member by way of a cam surface fixed for movement in unison with the steering shaft; the valve housing is thereby exclusively rotatable in relation to its valve housing axis but is immovably s
