Definitions

  • the invention relates to a hydraulic lash adjuster according to the preamble of claim 1.
  • Such play compensation elements are arranged, for example, in bores of rocker arms.
  • the bore in the rocker arm is designed as a continuous bore in which a disc is arranged, which is supported, for example, against a snap ring and which in turn serves as a support for the hydraulic play compensation element.
  • the disk has depressions in its surface that cooperates with the play compensation element, which allow oil to pass from the outside into the interior of the inner piston.
  • the invention has for its object to create a mounting unit consisting of the hydraulic lash adjuster on the one hand and the disc on the other hand with the simplest technical means and thus eliminate assembly errors.
  • the invention solves this problem in that the disk engages in the bore of the inner piston with radially resilient clamping projections when it contacts the end of the inner piston facing away from the pressure chamber. In this way, a non-positive connection between the hydraulic lash adjuster and the disc is achieved.
  • a circumferential groove can be provided in the bore of the inner piston, into which the clamping projections engage, whereby a positive connection is established.
  • a hydraulic lash adjuster 1 is mounted in a bore 2 of a rocker arm 3.
  • the hydraulic lash adjuster 1 consists of an outer piston 4 which is closed at one end and which in a longitudinal bore with little play longitudinally displaceably receives the inner piston 5.
  • the two pistons 4 and 5 enclose between them the high-pressure chamber 6, which is connected to the oil reservoir 8 provided in the inner piston 5 by a check valve 7 arranged in the inner piston 5.
  • the hydraulic lash adjuster is supported with its end facing away from the high-pressure chamber 6 on a disk 9 which is inserted into the bore 2 and in turn is supported there against a snap ring 10.
  • the disk 9 has, on its surface facing the hydraulic lash adjuster 1, recesses 11 which allow oil to pass into the oil reservoir 8.
  • the oil supply to the hydraulic lash adjuster 1 takes place via the oil hole 12 in the rocker arm 3.
  • the disc 9 has a central bore 13, into which the central pin 14 of a plastic part is inserted, which has clamping projections 15 which engage under radial prestress in the bore 16 of the inner piston 5 and thereby fix the disc 9 to the hydraulic play compensation element 1.
  • the adhesion of the disk can be improved by the fact that the clamping projections 15 engage in a circumferential groove 17 of the bore 16.
  • the clamping projections 15 are designed as a plurality of spring pulls which are distributed over the circumference and are curved radially outwards.
  • the clamping projection is formed by a bead 18 which projects radially outwardly from a circumferential rim 19 which is connected by a plurality of spokes 20 to a central hub 21 which in turn carries the central pin 14, which in turn is inserted into the central bore 13 of the disk 9.
  • FIGS. 5 and 6 differs from the previous one essentially only in that the bead 18 extends only over part of the peripheral regions lying between two successive spokes.
  • a clamping projection is formed by a wire ring 22 which is open at a circumferential point and which at its one open end merges into a radially inwardly directed spoke 23 to which the axially extending central one is located Pin 24 connects.
  • the additional component is in the form of a sheet metal part which, starting from a central plate 25, is enlarged in diameter in two successive stages 26 and 27 and ends in a circumferential ring 28 with a projecting collar 29.
  • the sheet metal part is provided with openings 30 at several peripheral points in the area between the central plate 25 and the peripheral ring 28.
  • the sheet metal part is attached to the disk 9 by an additional rivet 31 which is inserted into a bore in the central plate 25 and is pressed into the central bore 13 of the disk 9.
  • FIGS. 11 and 12 differs from the previous one in that the openings 32 also interrupt the collar 29.
  • a collar 33 is provided for fastening the sheet metal part 4, which collar is put through directly from the central plate 25.
