  • Tool engraving of a deformation tool for deforming with an active medium
    Patent number: 6286351
    Abstract: The invention concerns an engraved surface of a deformation tool which deforms a workpiece with an active medium, wherein the deformation tool has a pressure agent feed for the active medium and an engraved surface according to the desired final contour of the workpiece. Accordingly deformation methods are performed with hydro-deforming as well as of internal high-pressure metal forming of a wall of a workpiece by the engraved surface of the tool by way of the pressure medium. Upon withdrawal of the workpiece the pressure medium can pass to the engraved surface of the tool, during the deformation of the following workpiece no contact between the engraved surface and the workpiece wall occurs due to the pressure agent adhering to the engraved surface, whereby undesired deformations occur on the workpiece.

  • Spring strut for a motor vehicle having a bearing for a coil spring
    Patent number: 6273407
    Abstract: A bearing for a spring strut as well as for a coil spring of the spring strut is provided by way of spring supports which rest against supporting elements and are held in a mutually non-rotatable manner by twist fixations. The spring elements are constructed such that the same stiffnesses are formed over the circumference of the spring winding even though the twist fixation is provided. Furthermore, a spring plate of the lower bearing of the spring is provided. The spring plate is adjustably arranged on the shock absorber tube, and thus springs which have different lengths can be used.

  • Locking device for a rotatable latching element of a selecting device
    Patent number: 6269710
    Abstract: A locking device for a rotatable latching element with a bending spring is provided for a gear selecting system of a motor vehicle. In order to improve such a locking device in terms of the structural cost required, it is proposed to locate the bending spring on the latching element. A first end of the bending spring is mounted in a fixed location on the latching element and the bending spring rests at a distance from its second free end on a support located on the latching element. Corresponding to the free end of the bending spring, a shoulder is provided in the vicinity of a rotational axis of the latching element on the housing of the selecting device. To unlock the locking device, an actuating element engages between the fixed bearing and the support for the bending spring.

  • Cylinder head for a valve-controlled internal combustion engine
    Publication number: 20010009146
    Abstract: A cylinder head for a valve-controlled internal combustion engine with a cylinder head housing, in which there are bearing blocks for the inlet or outlet camshaft. At least one camshaft has a camshaft adjuster, by way of which the position of the drive wheel of the camshaft can be changed relative to the axis of rotation of the camshaft. At least the bearing block, which is provided next to the camshaft adjuster and is intended for the camshaft, exhibits a segment, whose width is reduced owing to a recess for the screw connection of the cylinder head housing. The bearing site, arranged next to the camshaft adjuster, provides a bearing sleeve for the camshaft, in such a manner that the segment of the bearing block that is provided with a reduced bearing block width is expanded to the actual bearing block width. The sleeve exhibits openings to supply oil for the camshaft adjuster.
