Definitions
- the invention relates to a vehicle component with a cavity having at least one opening for receiving hydraulic fluid and a means sealingly closing the opening.
- the invention is therefore based on the problem of specifying a vehicle component with a means sealingly sealing the opening, which can be produced inexpensively and ensures reliable sealing.
- the means is formed as a curved closure disk which can be inserted into the opening and deformed by applying an axial force under radial expansion.
- the vehicle component according to the invention has the advantage that instead of a complicated screw plug or a specially made Ab ⁇ sealing cover a comparatively simple and thus pronouncedi ⁇ ge closure plate is used, which does not have to be pressed, but placed loosely in the bore and then by an axial Force is deformed so that it seals the opening of the bore.
- the step of attaching a separate seal is dispensed with. insurance, for example, a security ring. It is also advantageous that the closure disc does not have to be positioned accurately in the bore.
- a particularly good seal can be achieved in the vehicle component according to the invention if the cavity or the bore has a shoulder in the region of the opening, onto which the closure disk with its edge can be placed prior to pressing.
- the bore may have a certain diameter, which is increased in the region of the opening.
- the invention provides that the closure disk after deformation is either flat or at least has a flat annular surface in the region of its outer circumference.
- the closure disk is predominantly radially expanded, so that it is positively and / or non-positively connected to the vehicle component.
- Such a bonded connection retains its sealing properties even in the event of temperature fluctuations.
- closure disc and the vehicle component consist of different materials. If different materials are used, the formation of chips is effectively prevented. It may be provided, for example, that the closure disc is made of steel, also the closure disc may be provided with a surface protection to prevent the formation of corrosion.
- Closing disks which have been produced in accordance with standard DIN 470 are particularly well suited, since such closure disks have proven to be particularly reliable; moreover, standardized closure disks are cost-effective.
- the vehicle component consists of a light metal alloy, in particular of an aluminum alloy, which is preferably sealed with a steel closure disc.
- the Curvature of the shutter disc causes after forming a certain bias remains, so that the material combination of steel and aluminum reliably seals despite the different thermal expansion coefficients even with temperature fluctuations.
- the vehicle component may be used as a component of an internal combustion engine, for example, it may be a chain tensioner. Further areas of use are, for example, camshaft adjusters or components of a vehicle transmission or a vehicle steering system. In general, the vehicle component according to the invention can be used everywhere where a hydraulic opening has to be sealed.
- Fig. 1 is a sectional view of a vehicle component with a in the
- FIG. 2 shows the vehicle component of FIG. 1 after forming
- Fig. 3 shows a variant in which the closure disk after Umfor ⁇ men is almost flat.
- the shutter disc 1 has a round, provided with a curvature basic shape.
- a closure disk according to DIN 470 is used, which has a thickness of 1.6 mm and a radius of curvature of 22 mm, for example, with a diameter of 16 mm.
- the closure disk 1 is provided with a galvanic Ober ⁇ surface protection, they can, for. B. be phosphated.
- the closure disk 1 rests on a shoulder 2 of a vehicle component 3 during assembly.
- vehicle component 3 is a module carrier for a chain tensioner which has been provided with a bore 4 in order to produce internal oil passages of a hydraulic system.
- the closure disk 1 is loosely placed in the opening 5 of the vehicle component, as shown in FIG. 1, with its convex surface outward, wherein the inner diameter of the opening 5 is selected to be slightly larger than the outer diameter of the closure disk 1 is. Since there is a small distance between the closure disk 1 and the inner circumference of the opening 5, the insertion of the closure disk 1 can be carried out easily with an automatic assembly machine. It is not necessary to accurately position the closing disk 1 in the opening 5.
- a stamp is used whose shape is adapted to the curvature of the closure disk 1.
- the stamp acts primarily on the edge 6 of the closure disk 1, wherein the edge 6 is pressed down radially by the applied axial force and re-formed.
- the vehicle component 3 consists of an aluminum alloy and the VerMED ⁇ disc 1 made of steel, the edge 6 digs on the entire circumference the shutter disk 1 in the aluminum material, so that a particularly secure connection of these two components is formed.
- Fig. 2 shows the vehicle component 3 after forming.
- the edge 6 of the reference disc 1 rests on the shoulder 2 over the entire circumference, so that a hydraulic fluid present in the bore 4 can not escape from the vehicle component 3 to the outside.
- the closure disk 1 After forming, the closure disk 1 has an almost flat annular surface. Since there is still a certain residual curvature of the closure disk 1, there is a permanent bias, which ensures a secure seal even at an elevated temperature.
- Fig. 3 shows a variant in which the shutter disc is almost flat after forming.
- the closure disk 7 has been formed with a higher forming force than the closure disk 1 shown in FIGS. 1 and 2. Furthermore, another forming tool was used, so that the almost flat surface of the closure disk 7 shown in FIG. 3 results. This increased deformation causes the edge 8 of the closure plate 7 digs even further into the bottom of the opening 5, so that these compounds Polg results in a reliable sealing of the bore 4.
