Turbocharger housing having a sealing device
A turbocharger housing is divided along the longitudinal direction into at least two housing halves. The turbocharger housing includes a sealing device between the two housing halves for sealingly connecting the two housing halves.
1. A turbocharger housing assembly, comprising:
a turbocharger housing having two housing halves dividing the turbocharger housing in a longitudinal direction thereof, each of said two housing halves including one half of a compressor housing, one half of a bearing housing, and one half of a turbine housing; and
a sealing device between said two housing halves for sealingly connecting said two housing halves to one another;
said sealing device including a first seal and a second seal being a different type of seal than said first seal;
said first seal extending in the longitudinal direction of said turbocharger housing along a first housing section including said turbine housing and said bearing housing of said turbocharger housing; and
said second seal extending in the longitudinal direction of said turbocharger housing along a second housing section including said compressor housing and at least a part of said bearing housing;
wherein said first and second seals overlap or intersect only partially in only one area.
2. The turbocharger housing assembly according to claim 1 , wherein said sealing device between said two housing halves comprises one or more seals selected from the group consisting of at least one beaded seal, an O-ring seal, and an elastomer seal.
3. The turbocharger housing assembly according to claim 2 , wherein said sealing device is fastened in a seal seat.
4. The turbocharger housing assembly according to claim 2 , wherein said one or more seals includes a flexible material that is a hard rubber, an elastomer, or a polymer.
5. The turbocharger housing assembly according to claim 1 , wherein said sealing device has a seal seat formed of a level surface or a level surface section, wherein said seal seat is provided on one or both sides of at least one said two housing halves to receive at least one seal of said sealing device.
6. The turbocharger housing assembly according to claim 5 , wherein a shape or cross section and/or dimensioning of said seal seat and/or of said seal is constant.
7. The turbocharger housing assembly according to claim 1 , wherein said sealing device has a seal seat formed of a depression, and said seal seat is formed on one or both sides of at least one of said two housing halves for receiving at least one seal of said sealing device.
8. The turbocharger housing assembly according to claim 7 , wherein said depression of said seal seat is one of a groove or a stepped profile.
9. The turbocharger housing assembly according to claim 7 , wherein said seal seat is molded or free formed in one of said two housing halves in the form of a depression, or is milled in one of said two housing halves by a milling cutter.
10. The turbocharger housing assembly according to claim 7 , wherein said seal seat is molded or free formed in said one or both sides of said at least one of said two housing halves in the form of a depression being a groove and/or a stepped profile.
11. The turbocharger housing assembly according to claim 1 , wherein:
said first seal is a beaded seal; and
said second seal is an elastomer seal.
12. The turbocharger housing assembly according to claim 1 , wherein said first seal and said second seal each contact both of said two housing halves.
