Definitions
- Field of the invention Pump in particular piston pump for high or low pressure, for quality or quantity-controlled internal combustion engines, in particular for motor vehicles, with at least one piston unit, which is actuated with the interposition of a roller or cup tappet of at least one cam or eccentric camshaft, wherein the Pump is designed as a plug-in pump with plug pump housing and is operatively connected to at least one cam or eccentric camshaft of the internal combustion engine or a non-rotatably connected to a component of the internal combustion engine cam portion or wherein the pump pump elements and a housing with guided therein by means of rolling or sliding bearings Has camshaft, wherein the housing attached to the internal combustion engine and the camshaft is rotatably connected to the internal combustion engine.
- Such piston pump designed as a plug-in pump is by the 1, 8 liter four-cylinder T-FSI engine from Audi, published as Part 1 in MTZ 10/2006 from page 734 and as part 2 in MTZ 1 1/2006 from page 884 known.
- the housing designed as a high-pressure pump for gasifying fuel Piston pump consists of a solid metal body, which is machined from the solid and flanged to the engine. It is correspondingly complex and expensive.
- the roller tappet is in communication with a cam portion rotatably connected to a camshaft for gas exchange valves of the engine.
- piston pumps are known as diesel high-pressure pumps from the "Motor News Europe” from 17.1 1 .2007 in connection with the essay "Volkswagen relies on common-rail systems from Bosch", published under www.motornews.at.
- generic pumps are shown, which are designed as single or multi-cylinder radial pumps and have a central camshaft in the housing of the pump, which is non-rotatably connected, in particular with a camshaft of the internal combustion engine.
- the housing is made of cast iron or an aluminum casting, which is machined, and attached via a flange to the internal combustion engine.
- the object of the invention is to modify a generic pump so that even at relatively low quantities per individual variant, a cost-effective production is possible. In this case, even a cost-effective production in a variety of different installation situations and different individual functions, such as drive and fixation as high pressure or low pressure or as a vacuum pump should be possible. Summary of the invention
- the object of the invention is achieved in that the housing has a plurality of components which are manufactured individually and assembled into a structural unit.
- the housing consists of core components and variation components, which are joined together to form an end housing.
- the core components are designed to be constant depending on the pump used as high pressure, low pressure or vacuum pump and in single or multi-cylinder design, and are maintained unchanged, the variation components corresponding to the connections of the pump to its drive point, z. B. to the cylinder head or the unit drive, or vary according to the uses.
- the core components of the housing consist of at least two shell parts, which are interconnected.
- This housing core which is formed by the core components, serves to receive the plungers and the piston unit (s) or to receive the camshaft or attach or form a flat in plug-in pumps.
- the variation components represent the transitional parts with which the pump is adapted to a variety of growing conditions or the various uses.
- the core and / or variation components are made of different materials, which correspond to the load or force requirements or are adapted to the wear loads.
- the components can therefore be made of steel or stainless steel, aluminum or another material.
- the components can be coated to z. B. wear, friction or corrosion to minimize or prevent.
- PVD, CDV or electroplated coatings come into question.
- the core and / or variation components as sheet metal parts, in particular sheet steel parts, executed and manufactured by means of metal forming. This results in a very simple and cost-effective production of the individual components. They are then fastened together by known joining methods such as welding, riveting, punching rivets or screws, taking into account whether these fasteners must be tight or permeable.
- Figure 2 a likewise perspective view of a reshaped
- FIG. 3 is a perspective view of a housing core made from the
- FIGS. 1 and 2 Shells according to FIGS. 1 and 2 is assembled, Fig. 4 u. 5 designed as flanges variation components for connection to the housing core depending on the intended use of the pump, Fig. 6 u. 7 different perspective views of a housing, which is composed of the components according to FIGS. 1 to 5,
- FIG. 8 is a perspective view of a basic component with attached variation components;
- FIG. 9 shows a shell component suitable for FIG. 8,
- FIG. 10 u. 1 different perspective views of a housing, which is assembled from the parts of Figs. 8 and 9,
- FIG. 12 shows a housing core on which a variation component is formed
- FIG. 13 u. 14 different perspective views of a variation component composed of individual parts
- FIG. 15 u. 16 different perspective views of a housing, which is assembled from the parts according to the figures 12 to 14, a perspective view of a finished housing of a pump, which is assembled from core and variation components and a section through the housing according to Figure 17 withlichbau th rolling bearings ,
- 1 and 2 designate core components, which are designed as shell parts of different shapes.
- 3 and 4 designate variation components which are designed as flange pieces in FIGS. 4 and 5 and as flange extensions in FIGS. 13 and 14.
- the variation components 3 and 4 according to FIGS. 4 and 5 are connected to the core components 1 and 2 according to FIG. 3, so that a complete housing 5 according to FIGS. 6 and 7 is produced.
- the core components 1 and 2 according to the figures 8 and 9 are also formed, with variation parts 3 and 4, which are formed as flanges similar to Figures 4 and 5, are attached to the core member 2 and secured, for. B. by welding. After joining the parts, the housing 5 according to FIGS. 10 and 11 is ready.
- the core component 2 according to FIG. 12 is designed like a pot and provided with an integrally formed variation part 4 corresponding to the flange in FIG. Attached thereto is then the variation component 3 according to FIG. 13 or 14, so that a housing 5 according to FIG. 15 or 16 is produced.
