Definitions

  • the invention relates to a between a rocker arm and a valve stem of an internal combustion engine ball joint, consisting of a cooperating with the rocker arm pin with a spherical end face, which cooperates with a spherical cap of a joint shell, which on its side opposite the spherical cap has a flat surface with which it opposes the valve stem rests, with the pin or a component connected to it starting from a holding element which engages behind the outer surface of the joint shell in such a way that it is held captively on the pin.
  • the invention has for its object to avoid with a simple structural measure unwanted play between the cooperating with the rocker arm pin with a spherical end face on the one hand and the spherical cap of a joint shell on the other hand and at the same time to achieve that on the flat surface of the joint shell, which cooperates with the valve stem , no unwanted wear occurs.
  • the holding element is designed as a spring element which rests under elastic prestress on the joint shell and thus holds the spherical end face of the pin in play-free contact in the spherical cap, the spring element being shaped and / or at such a point the joint cup rests that it is pivoted by such an angular amount with respect to the longitudinal axis of the pin that its flat surface runs parallel to the end face of the valve stem.
  • FIGS. 4, 6 and 8 plan views of the embodiments according to FIGS. 3, 5 and 7.
  • a known hydraulic lash adjuster 2 is arranged in a rocker arm 1 and has a pin 4 with a spherical end face 5 at its end facing the valve stem 3.
  • This spherical end face 5 engages in the spherical cap 6 of the joint shell 7, which has a flat face 8 at its opposite end, with which it is in contact with the end face of the valve stem 3.
  • the jacket surface 9 of the joint shell 7 is spherical.
  • a leaf spring 10 is provided, which sits on the one hand with a cylindrical collar 11 on the end of the piston of the hydraulic play compensation element 2 and is fastened there by rolling into a circumferential groove, while on the other hand has a bow-like leg 12, which has a circular bore, with the edge of which it rests on the spherical lateral surface 9 and thereby ensures play-free contact between the spherical cap 6 and the spherical end surface 5.
  • the edge of the circular bore is slightly shaped in the form of a spherical cap to form a contact surface, the surface of which is adapted to the lateral surface 9 of the joint shell 7.
  • FIG. 2 shows an embodiment of the type that can be used in motors with manual play adjustment.
  • the rocker arm 13 has a bore 14 into which an extension 15 of the Pin 4 is inserted.
  • the pin 4 is here, as in the example described above, in contact with the joint shell 7, which in this case, however, has no spherical outer surface. Rather, it has at its end adjacent to the spherical cap of the pin 4 a radial flange 16, against whose radial surface 17 facing away from the pin 4 the first leg 18 of the leaf spring 19 bears.
  • the second leg 20 of the leaf spring 19 is embedded on the one hand between a flat surface of the rocker arm 13 and on the other hand a radial surface 21 of a radial flange 22 which is arranged on the pin 4 at a distance from its spherical end face.
  • Figure 2 shows that the leg 18 of the leaf spring 19 in this embodiment acts so eccentrically on the radial surface 17 of the radial flange 16 that the joint shell 7 is pivoted by such an angular amount relative to the longitudinal axis of the pin 4 that its flat surface 8 parallel runs to the end face of the valve stem 3. This ensures that when the joint shell 7 is placed on the valve stem 3, no additional wear-promoting tilting movement of the joint shell is required.
  • Figures 3 and 4 corresponds essentially to the embodiment of Figure 2.
  • Figures 3 and 4 show that the second leg 20 of the leaf spring 19 surrounds the extension 15 of the pin 4 fork-like and that the ends 23 of the fork arms so are angled so that they engage behind the radial flange 22 and thus prevent the leaf spring from slipping.
  • FIGS. 5 and 6 largely corresponds to the overall structure. Design according to Figure 1, while the attachment of the leaf spring largely corresponds to Figures 3 and 4.
  • FIGS. 7 and 8 show constructions in which the spring element is formed from round wire. Otherwise, this construction also corresponds in its basic structure to the previously described exemplary embodiments.
  • FIGS. 9 and 10 show a further variant, which differs from the previous one in that the flat surface 8 of the joint shell 7, with which it rests against the valve stem 3, has a larger diameter than the valve stem 3
  • Both legs 18 of the leaf spring 19 bifurcated at their ends abut on both sides of the valve stem 3 against the region of the flat surface 8 which projects beyond them and thus hold the joint shell 7 in contact with the spherical end surface of the pin 4.
