Definitions
- the invention relates to a roller tappet, in particular for a high-pressure fuel pump or for a valve train of a quality- or quantity-controlled internal combustion engine, with a housing, at its drive-side end two diametrically opposite and depressed by an outer shell of the housing flax, each with a receptacle are applied, in which a cam roller bearing bolt is mounted, wherein an inner casing of the housing, viewed in the drive-remote direction axially below the cam roller, is penetrated by a bridge piece, the output-side end has a system for a ram follower part.
- a generic roller tappet is shown in FIG. 1 of DE 10 2006 028 851 A1. Its bolt for the cam roller is attached either by frontal caulking or by radial point or wobble riveting form and locks.
- this object is achieved in that, except for the flax, at least largely uncontrolled outer shell of the housing, seen in the drive direction immediately above arcuately similar by the quiver longs running through the housing tops of the flax is shown as a closed circumferential ring, followed by the drive-side end connects the receptacles in the flax are in the form of recesses emanating from their upper sides and surrounding the bolts in a manner similar to a half-shell.
- the preferably made of inexpensive sheet steel housing of the roller tappet whereby its massive training is conceivable, thus can be tamper-free finely processed in a centerless grinding process on its outer shell.
- the lying at the drive-side end closed circulation ring has an outer diameter as the other housing.
- the bolt lies in the half-shell-like shots of the flax over its ends either Jose "or he is held according to a further concretization of the invention by slightly over its tops cantilevered ends of side surfaces of the recordings, so that at least a good transport security is created Specialist is clear that is an assembly of the bolt with cam roller by simply inserting / snapping "from above” as conceivable inexpensive.
- the bolt undergoes an axial guidance over start-up of its respective end on an inner side of a bow-like segment of the peripheral ring in the corresponding flat.
- the bolt with only one ring segment of its respective forehead on the circulating ring and is axially slightly movable.
- the flax with the receptacles are preferably connected in one piece to the housing and are generated, for example, by inserting a jacket region of the housing radially inwards.
- a particularly easy to perform heat treatment process for the bolt is the subject of another subclaim. Accordingly, this should be through hardened.
- the bridge piece with the system for the ram following part can be integrally connected to the inner casing of the housing.
- it is preferably shown as a separate and thin-walled element such as a sheet metal component, which abuts on lower surfaces of the flax in the drive direction and in the output direction behind one or more of the inner shell of the housing outgoing snap-lugs o. The like.
- FIG. 1 is a perspective view of a roller tappet with an explosively illustrated cam roller
- FIG. 2 is a plan view of the roller tappet
- Fig. 3 is a partially sectioned side view of the roller tappet
- roller tappet 1 for a high-pressure fuel pump of an internal combustion engine.
- the roller tappet 1 consists of a housing 2, in whose drive-side end 3 two diametrically opposite and pressed by an outer casing 4 of the housing 2 flax 5 are each applied with a receptacle 6.
- a bolt 8 is mounted in the receptacles 6, a bolt 8 is mounted.
- An inner jacket 9 of the housing 2 extends axially below the cam roller 7 through a thin-walled bridge piece 10 made of sheet steel. From the outer circumferential surface 24 protrudes integrally a finger-like projection 25 from. This extends to illustrate an anti-rotation through an opening 26 of the housing 2.
- a driven-side end 11 of the bridge piece 10 has a system 12 for a ram following part (here pump piston).
- the up to the flax 5 ungestufte outer sheath 4 of the housing 2 is shown above in plan view similar to the bow string through the housing 2 running tops 13 of the flax 5 as a closed circumferential ring 14.
- the recordings 6 in the flax 5 are formed as outgoing from the tops 13, the bolt 8 half-shell-like umschmiegende recesses.
- the housing 2 in the centerless grinding its outer shell 4 is no longer, as stated above, tilt. s
- the bolt 8 with cam roller 7 is simply inserted in the mounting case from above into the receptacles 6 and snapped behind slightly projecting ends 18 of side surfaces 19 of the receptacles 6. As can best be seen from FIGS. 2, 4, the bolt 8 experiences an axial guidance over the start of its respective forehead 15 on an inner side 16 of a bow-like segment 17 of the revolving ring 14 in the corresponding flat 5.
