Definitions

  • the invention relates to a pivot bearing for door holding rods of door locks for motor vehicle doors, consisting essentially of a two-armed, encompassing the articulated end of the door holding rod and attached to one of the door arrangement parts, door or door pillar, a bearing axis fixed therein axially immovable and a bearing recess in the articulated end of the Door support bar.
  • Swivel bearings of this type for the door support rods of motor vehicle door locks are generally used on the one hand, but on the other hand also have a number of disadvantages.
  • the two arms of the bearing block rest on the two broad sides of the door holding rod and the bearing axis of the bearing block is formed by a screw or rivet bolt passing through a pivot eye on the pivoting end of the door holding rod.
  • the door support bar usually formed by a flat material blank, only bears against the bearing axis over a width corresponding to its own material thickness, from which it follows that the door handle rod occurring, resulting from the braking and striking forces of the door arrester, is directed transversely to the bearing axis and in particular occurs suddenly Force peaks must be absorbed on a very small area on the one hand of the bearing axis and on the other hand of the articulation eye of the door holding rod. After a certain period of operation of the door arrester, this leads to a deflection, in particular the pivoting eye of the door holding rod, and thus to noise formation within the door arrester.
  • the invention has for its object to improve a pivot bearing for the door support rods of motor vehicle door locks in such a way that a significant increase in the storage area of the door support rod on the bearing axis is achieved without significant increase in manufacturing costs and the possibility of arranging maintenance-free storage is achieved .
  • the invention further proposes that the bearing sleeve passing through the bearing recess at the articulation end of the door holding rod is formed in one piece from a cylindrical tube material section and is connected to the door holding rod by means of a press fit.
  • the bearing sleeve can be formed by axially upsetting a cylindrical tube material section in a single operation and can be connected to each other with respect to each other with respect to the door holding rod opposite bulging by means of a press fit with the side surfaces of the door holding rod, with as a starting material for the bearing sleeve a relatively rough cutting of a pipe material, which in turn also does not need to be of high accuracy, since the bearing sleeve is brought to a dimensionally stable shape by upsetting.
  • the effort required for attaching the bearing sleeve according to the invention is therefore very low.
  • the bearing sleeve connected to the door holding rod also permits the arrangement of maintenance-free storage for the door holding rod, in such a way that the bearing bush is mounted on the bearing axis of the bearing block by means of a bushing made of maintenance-free bearing material, which is provided on both ends with a collar turned outwards.
  • the bushing for the maintenance-free mounting of the bearing sleeve on the bearing axis consists of a steel backing with a sintered bronze layer and a PTFE-filled bearing material.
  • the invention further proposes that the bearing axis is formed by a pin provided on one side with a head and then with a circumferential knurl, which on the other hand has a collar that rests against the inner surface of the second arm of the bearing block Arm of the pedestal Has pin extension and is riveted to the associated arm of the bearing block via the pin extension.
  • this also results in a simplified assembly of both the bearing block and the mounting of the door support rod.
  • the subject matter of the invention therefore provides a pivotable bearing for the door holding rod of motor vehicle door locks that can be machined with little effort and can also be designed maintenance-free as a result of enlarged bearing surfaces and therefore lower bearing pressures.
  • the door retainer 1 shown in the exemplary embodiment consists of a holder housing 3 fastened to a door arrangement part, door or door pillar by means of screw bolts 2, in which spring-loaded brake bodies, not shown in detail, cooperating with thickening 4 of the door holding rod 5 for applying braking and holding forces and for determining the Door in its open end position, an end stop 6 are arranged and a pivot bearing 7 for the door support rod 5, which on the other door arrangement part, Door or pillar is hinged.
  • the swivel bearing 7 comprises a bearing block 8 formed from a U-shaped sheet metal blank, one of which extends through arms 9 and 10 which extend through both arms and form the bearing axis for the door holding rod 5, and a bearing sleeve 13 connected to the bearing eye 12 of the door holding rod 5.
  • the bearing sleeve 13 13 is formed by a tube material blank deformed by means of upsetting and at the same time non-positively connected to the door holding rod 5 by means of a radial press fit, the tube material blank being provided with axial ridges 14 by means of axial upsetting, by means of which it is press fit and at the same time also form-fitting on the two broad sides 15 of the door holding rod 5 is set.
  • the bearing sleeve 13 is provided with a lining made of maintenance-free material, the lining being formed by a bushing 17 provided at both ends with a radially placed collar 16 and the bushing 17 made of a bearing material with a steel back and on this sintered bronze layer with a PTFE filling.
  • the bearing axis 11 of the pivot bearing is formed by a pin which is provided on the one hand with a head 18 and then with a circumferential knurl 19 and with the circumferential knurl 19 passes through one arm 9 of the bearing block 8.
  • the pin has a collar 20, by means of which it rests on the inside 21 of the other arm 10 of the bearing block 8.
  • the pin 20 is subsequently provided with a pin extension 22 by means of which it is riveted to the other arm 10 of the bearing block 8.
