Problems solved by technology

It is also important to point out that in individual cases chips can form during the pressing, which can block the hydraulic channels again
Another disadvantage that can be seen here is that the cover plate is a special turned part, so the costs of this solution are relatively high

Embodiment Construction

[0019] The sealing disc 1 has a round basic shape with a dome. In the exemplary embodiment shown, a sealing disc according to DIN 470 is used which, for example, has a thickness of 1.6 mm and a bending radius of 22 mm at a diameter of 16 mm. The sealing sheet 1 is provided with an electroplated surface protection layer, which can be phosphated, for example.

[0020] as in figure 1 It can be seen from the figure that the sealing sheet 1 rests on the shoulder 2 of the vehicle component 3 during installation. This vehicle component 3 is a module carrier for a chain tensioner, which is provided with an orifice 4 for creating a built-in oil sump for the hydraulic system.

[0021] Such as figure 1 As shown, for mounting, the sealing disc 1 is inserted loosely with its convex side outwards into the opening 5 of the vehicle component, wherein the inner diameter of the opening 5 is chosen to be somewhat larger than the outer diameter of the sealing disc 1 . Since there is a small g...

Abstract

The invention relates to a vehicle component, comprising a cavity with at least one opening for containing hydraulic fluid and a closing means, sealing said opening, whereby the means is embodied as a domed closure disc (1, 7) which may be inserted in the opening (5) and deformed with radial extension by application of an axial force.

Description

technical field [0001] The invention relates to a motor vehicle component comprising a cavity having at least one opening for receiving hydraulic oil and means for sealingly closing said opening. Background technique [0002] The problem often arises in the automotive industry that the openings must be closed oil-tight. It is necessary to install orifices in a series of hydraulic vehicle components in order to create passages for hydraulic oil. In connection with this, these openings must be reliably sealed, which in practice entails high costs. [0003] DE 86 14 676 U1 proposes a screw-in fitting with a plastic sealing ring. However, this solution has the disadvantage that the opening of the vehicle component to be sealed must be provided with an internal thread, and the production of such screw-in fittings is relatively cumbersome and therefore expensive. [0004] A locking screw is described in DE 101 56 507 A1 for the tight closing of openings. In order to be able to...
