Definitions

  • the invention relates to a cam follower for actuating a gas exchange valve of an internal combustion engine, comprising a housing and a cam roller mounted in a recess of the housing for tapping a cam of a camshaft.
  • the cam roller is radially supported by means of a needle bearing running in its bearing bore on a pin spanning the recess and supported on the housing, and the width of the needle bearing is significantly greater than the width of the cam roller in the region of the cam tappet.
  • a cam follower with such a cam roller is considered from the generic DE 101 21 798 A1 is known and is particularly suitable for use in variable stroke valve trains with axially displaceable cam groups whose different cam lobes are selectively transmitted by means of the cam follower on the gas exchange valve.
  • the Hertzian pressure in the needle bearing does not exceed the allowable load limits, corresponds to the width of the cam roller in the region of the cam tap in the essentially the width of a cam and in the region of the needle bearing whose width is significantly greater than the width of a cam.
  • the known from the cited prior art cam follower is provided with a stepped on both sides in diameter cam roller whose diameter stages have a correspondingly large width.
  • Object of the present invention is to provide a cam follower of the type mentioned with a manufacturing technology favorable cam roller.
  • the width of the needle bearing should be clearly and expediently 30% to 60% greater than the width of the cam roller in the bearing bore and significantly larger than the clear distance of Rollenanlauf vom which limit the recess and where the cam roller starts axially with their faces.
  • the cageless full complement or cage-guided needle bearing protrudes from the bearing bore.
  • the basis for this embodiment according to the invention is the fact that the Hertzian stresses on the comparatively strongly curved inner race are significantly greater than on the comparatively slightly curved outer race of the needle bearing, so that the width of the cam roller in the region of the bearing bore, i. the width of the outer race, significantly smaller than the width of the needle bearing, which is decisive for the Hertzian pressure, i. the width of the inner race, can be dimensioned.
  • the cam roller should have flat end faces. This means that the cam roller has the same width in the area of the cam tap and in the area of the bearing bore and, apart from transitional chamfers or fillets to the cam tap face and the bearing bore, has no production-consuming diameter steps.
  • roller contact surfaces whose clear distance is significantly smaller than the width of the needle bearing and is selected so that the cam roller is mounted with predetermined axial play in the recess.
  • the roller abutment surfaces are preferably positioned so that the cam roller and the needle bearing have a common transverse symmetry plane. Neglecting the axial play of the needle bearing and the cam roller means that the axial projection of the needle bearing from the bearing bore is identical on both faces of the cam roller.
  • the roller contact surfaces can also be positioned so that the cam roller eccentrically rotates with respect to the needle bearing, so that, for example, the needle bearing protrudes from the bearing bore only on that end side of the cam roller on which clearance for an adjacent cam is required.
  • the needle bearing can roll either directly on the bearing pin or on a recorded on the bearing pin bearing bush, which is preferably received radially slidably on the bearing pin.
  • the cam follower is a linearly guided ram or a tilting, oscillating or drag lever mounted centrally or end pivotally mounted.
  • the rocker arm whose elongated housing at its first end portion a socket for receiving a condyle of the rocker pivotally supporting support member, at its second end portion an actuating surface for the gas exchange valve and in its central portion of the recess two limiting and the bearing pin supporting housing sections should where the roller contact surfaces run.
  • the housing should be a sheet-metal forming part with a U-shaped cross-sectional profile which is composed of side walls extending on both sides of the cam roller and a bottom connecting the side walls with the joint socket and the actuating surface.
  • the bottom is provided with an opening for the cam roller, and the Rollenanlauf vom are formed by extending in the longitudinal direction of the housing portions inner edges of the opening.
  • the roller contact surfaces are by punctual elevations on the facing each other Inner sides of the side walls formed. While a survey for the axial guidance of the cam roller is sufficient per side wall, more surveys per side wall can be provided.
  • the elevations expediently produced by embossing the side walls can be in point or surface contact with the end faces of the cam roller.
  • the U-shaped cross-sectional profile is preferably oriented such that, with respect to the bottom, the side walls and the socket rise in the same direction.
  • the U-profile of the cam follower is closed to the gas exchange valve.
  • FIGS. 1 to 3 a first embodiment of a cam follower according to the invention for a gas exchange valve drive of an internal combustion engine is disclosed in various views.
  • a follower lever 1 cam follower comprises an elongated housing 2, which is made of sheet metal material in a cold forming process, and a cam roller 3, which is mounted in a recess 4 of the housing 2 and serves for low-friction picking a cam of a camshaft.
  • the housing 2 has at its first end portion a dome-shaped socket 5 for receiving a spherical condyle of a rocker arm 1 pivotally supporting support member at its second end portion an actuating surface 6 for a gas exchange valve and in its central portion two the recess 4 limiting housing sections 7, in which a bearing pin 8 spanning the recess 4 and supporting the cam roller 3 radially is supported by means of end caulking.
  • the housing 2 has a U-shaped cross-sectional profile, which consists of both sides of the cam roller 3 extending side walls 9 and the side walls 9 connecting bottom 10 with the joint socket 5 and the actuating surface 6.
  • the cross-sectional profile is closed to the gas exchange valve and thus oriented so that rise with respect to the bottom 10, the side walls 9 and the socket 5 in the same direction.
  • the bottom 10 is provided with an opening 11 for the cam roller 3.
  • FIG. 4 takes place the bearing of the cam roller 3 on the bearing pin 8 both by means of a full complement, ie cageless needle bearing 12 whose outer race is formed by the bearing bore 13 of the cam roller 3, as well as by means of a bearing bush 14 which is radially slidably received on the bearing pin 8 and the Inner raceway of the needle bearing 12 forms.
  • a full complement, ie cageless needle bearing 12 whose outer race is formed by the bearing bore 13 of the cam roller 3, as well as by means of a bearing bush 14 which is radially slidably received on the bearing pin 8 and the Inner raceway of the needle bearing 12 forms.
  • the width B1 of the needle bearing 12 is not only significantly greater than the width B2 of the cam roller 3 in the region of the Nockenabgriffs, ie the width of its outer circumferential surface 15, but also significantly greater than the same width B2 of the cam roller 3 in the region of its bearing bore 13 , so that the needle bearing 12 and the bearing bush 14 with respect to the end faces 16 of the cam roller formed just here 3 protruding.
  • B1 is about 40% larger than B2.
  • FIG. 6 shows, in which only the housing 2 'of the cam follower also designed as a follower lever 1' is shown in cross section.
  • the drag lever 1 ' differs from the drag lever 1 only by the Rollenanlauf vom 17', which are formed in this case by embossed punctiform elevations on the mutually facing inner sides of the side walls 9 '.
  • a further, but not shown alternative with respect to the roller contact surfaces is that the distance of the side walls 9 not at the second end portion of the housing 2, (as in FIG. 3 shown), but already in its middle section to the width B3 to zoom out.
  • the end faces 16 of the cam roller 3 would start axially against the converging inner sides of the side walls.
