Definitions
- the invention relates to a housing cover according to the preamble of claim 1.
- EP 0 268 200 B1 discloses a generic valve cover for the Cylinder head of an internal combustion engine.
- the lid has holes in its bottom for carrying out threaded bolts designed as stud bolts. In the Holes extend through rubber sleeves. On the one hand, these are used for sealing the stud and on the other hand they dampen the transmission of structure-borne noise.
- threaded bolts designed as stud bolts. In the Holes extend through rubber sleeves. On the one hand, these are used for sealing the stud and on the other hand they dampen the transmission of structure-borne noise.
- the rubber sleeves act as rubber springs and ensure that one sufficient sealing is generated.
- the invention has for its object a generic housing cover to improve with regard to the sealing effect of the seal on the edge of the lid.
- the spring body When tightening the fastening screws or nuts, a defined one can be used Preload is generated, the spring body is so with the Rubber sleeve connected so that the fastening screw is on the spring body axially supported.
- the spring body should preferably consist of steel.
- the spring body as a leaf spring.
- Other spring bodies which are formed, for example, from spring band steel, could also be used reach.
- the spring body should be at least in the range Contact points with the cover have a sound-absorbing pad.
- FIG. 1 shows a housing cover (1) in the form of a valve cover for Internal combustion engines.
- the housing cover (1) is made of aluminum.
- For Sealing of the cylinder head (2) is an elastomer seal on the edge of the cover (3) (4) arranged.
- Rubber sleeves (7) which are attached to the cover (1), are used to seal the stud bolts. are connected.
- the rubber sleeves (7) can be vulcanized in or pressed in.
- a spring body (8) made of steel strip is form-fitting with the Rubber sleeve (7) connected.
- the spring body (8) is supported on the metal surface (9) of the cover (1).
- the spring body (8) When tightening the nut (10) of the stud (6) the spring body (8) axially pressed and thus generates a biasing force on the Seal (4).
- the spring body (8) Since the spring body (8) is made of metal, the contact pressure remains largely over a long period of time and over a wide temperature range constant. In contrast to the rubber sleeve (7), no aging occurs. In addition, this spring body (8) can flow / set the seal (4) compensate. A sound attenuation can be found on the underside of the spring body (8) thin sound-absorbing layer (11) can be applied.
