Definitions
- the invention relates to a roller tappet, in particular for a high-pressure fuel pump or for a valve train each of a quality or quantity-controlled internal combustion engine, with a housing which is immanent at its drive-side end of a startup of a cam or eccentric slide-bearing roller, wherein, in the housing direction seen, the housing below the roller has a bridge piece, which bridge piece on its one output side end of the housing facing an end face has a plant for a ram successor part.
- a generic roller tappet is disclosed in DE 32 47 026 A1.
- a roller sits in a cylindrical pocket of a drive side of a housing. The latter protrudes with its drive-side end half the height of the roller to the holder, which role is taken in a one-piece connected to the housing bridge piece.
- An axial securing of the roller is provided by separate pins. It is disadvantageous in the case of the aforementioned roller tappet that it can only be produced in a complicated manner in mass production. So must be extremely tight, for example, in the holding area for the role to be tolerated.
- the invention has for its object to provide a roller tappet of the aforementioned type, in which the cited disadvantages are eliminated.
- a roller tappet is to be created, which can be mass-produced extremely inexpensive.
- this object is achieved in that in an indentation of a drive-side further end face of the bridge piece, a shell piece separated from a ring such as a rolling ring sits like a half or third shell, in which the roller is slidably mounted directly.
- a roller tappet in which the aforementioned disadvantages are eliminated. It is applied to initiate the forces a separated from a present as a mass of Wälzring shell piece.
- Wälzring can, for example, a cam follower ring from the valve train technology use, as it is found, inter alia, with rocker arms or roller tappets.
- the standard component is subjected to a separation process such as cracking so that, for example, two or three shell pieces are present per rolling ring.
- the indentation for the shell piece can, for example, describe a cylindrical or Gothic profile.
- the proposed roller tappet should, for example, follow a periodic lift generator such as a cam or eccentric in a high-pressure fuel pump.
- the roller tappet can also be used as a cam follower in a valve train of an internal combustion engine (cup or roller tappet with top or bottom camshaft).
- the roller tappet is excellently suited for use in today's high-speed pumps.
- the housing of the roller tappet is made of a lightweight material such as steel by deep drawing technology.
- the opposing flax are expediently introduced for a lateral start of end faces of the roll.
- these flax, but also other jacket areas of the housing may be provided with respective recesses.
- one-piece loss prevention areas such as projections for the slightly axially movable roller. It is clear to the person skilled in the art that it is not necessary to work with very high precision at this point, so that this makes a further contribution towards lowering the production costs.
- protrusions for holding the roller come after a specification of the invention, for example.
- Knob-like projections in question which are slightly from the insides of the flax over the end-side end portions of the role.
- Verlierschs Symposiume can also exist as emanating from the inner shell of the housing and diametrically opposed, finger-like approaches, the lower sides engage in sections on the role. It is clear that a vertex of the roll protrudes over tops of the lugs.
- the roller can also be held in the face area by notch-like indentations which extend from the outer casing of the housing and run radially inwards. More specifically, the role of formed by the indentations, inner roof segments is fixed.
- the bridge piece in which the shell piece is received, is expediently shown as a separate component, but may also be integrally connected to the housing.
- bridge piece consists for example of thin-walled steel sheet. This is another contribution towards lightweight construction and reduction of manufacturing costs.
- a nasenar- term approach of the bridge piece project through a corresponding opening in the housing.
- a simple rotation for the roller tappet is shown. It can be dispensed with a separate VerFommeskorper shirt of the roller tappet.
- the latter can also be produced by extrusion or machining.
- it is proposed according to the invention to generate a knob-like projecting system for the ram succession part on an end face of the bridge piece, which faces a driven-side end of the housing.
- This system can be represented, for example, as sections of material suppression / embossing, which starts from a further end face of the bridge piece.
- the roll may be in the form of a ring or cylinder.
- FIG. 1 is an exploded view of a roller tappet with a shell piece
- FIG. 2 shows the roller tappet as previously mentioned in the assembly
- FIGS. 4, 6 and 8 show the roller tappet in assembly, in each case matching the variants of the tethering device according to FIGS. 3, 5 and 7.
- DETAILED DESCRIPTION OF THE DRAWING FIG. 1 discloses a roller tappet 1 used as a counter cam or eccentric cam in a high pressure fuel pump (for example, diesel fuel delivery).
- the roller tappet 1 has a substantially cylindrical housing 2, via whose outer casing 21 a guide takes place in a receptacle of the high-pressure fuel pump or an environmental design.
- the housing 2 is projected transversely by a roller 4.
- the roller 4 runs with their end faces 14 according to the solutions according to the figures 1 to 6 on inner sides of respective flax 13 at. The latter are designed as material impressions.
- the roller 4 is slidably mounted in a shell piece 1 1, which is separated from a present as a standard element Wälzring.
- a separation process for example, cracking comes into question, so that each Wälzring two or three shell pieces can be generated.
- the shell piece 1 1 is received in a complementary indentation 9 an end face 10 of a separate, thin-walled bridge piece 5.
- the bridge piece 5 is made of sheet steel and rests with edge regions of its end face 10 on undersides of the flax 13.
- the bridge piece 5 has a nose-like projection 23. This protrudes through (see Figure 2) a window-like opening 24 in the housing 2 and thus forms a rotation 22 for the housing 2.
- a button-like projecting system 8 which is present as an approaching starting from the end face 10 material Fudschreibung.
- a shaft of a pump piston is located in the installation case.
- the roller 4 is held by Verliertechnischs Kunststoffe 15. These are formed as projecting from the flax 13 outgoing projections 16 and consist according to FIGS. 1, 2 of knob-like projections 17, which point in the axial direction of the roller 4.
- Verliertechnisches Symposium 15 reveal the figures 3, 4. Accordingly, the supernatants 16 per flat 13 by a roof portion 18 of a shell-like indentation 19 are formed.
- the captive securing regions 15 are designed as two opposing finger-like projections 20. These start from the inner shell 12 of the housing 2 at the drive-side end 3 and extend orthogonal to the axial line of the roller 4th
- two circumferentially spaced, notch-like indentations 25 are provided for representing the captive securing regions 15 in the outer casing 21 of the housing 2 at the drive-side end 3, which form inner roof segments 26, under which the roller 4 is held.
- the roller tappet 1 whose housing 2 and bridge piece 5 consist of thin-walled sheet steel and in which at the same time an unobtrusive sliding bearing of its roller 4 is realized in a shell piece 1 1 separated from a rolling ring, has a simple construction and can be mass-produced inexpensively.
- the roller tappet 1 is ideal for use in a diesel or petrol pump according to the latest state.
