Abstract

A charging device may include a turbine housing and a bearing housing. The bearing housing may have a bearing arrangement for a shaft carrying a turbine wheel and a compressor wheel. A gasket may be arranged by metal-to-metal connection between a radially orientated flat surface of the turbine housing and a radially orientated flat surface of the bearing housing. The gasket may be resilient.

Claims (28)

1. A charging device comprising:

a turbine housing,

a bearing housing having a bearing arrangement for a shaft carrying a turbine wheel and a compressor wheel, a gasket arranged by metal-to-metal connection between a radially orientated flat surface of the turbine housing and a radially orientated flat surface of the bearing housing, wherein the gasket is resilient; and

a guide vane cage disposed between the turbine housing and the bearing housing by a floating contact connection, wherein the guide vane cage forms a radially extending side wall of a nozzle.

2. The charging device according to claim 1 , wherein the gasket is a disc spring.

3. The charging device according to claim 1 , wherein the gasket is at least one of a heat-resistant steel material and a nickel-based alloy.

4. The charging device according to claim 2 , wherein the disc spring is disposed at a contact point with the turbine housing and the bearing housing comprises rounded contact surfaces.

5. The charging device according to claim 1 , wherein the gasket is disposed in a radial recess in a flange of the bearing housing.

6. The charging device according to claim 4 , wherein the gasket includes a contact surface having a heat-resistant coating.

7. The charging device according to claim 1 , wherein the gasket is formed by at least two disc springs.

8. The charging device according to claim 1 , wherein the gasket is a heat-resistant steel material.

9. The charging device according to claim 8 , wherein the gasket is disposed in a radial recess in a flange of the bearing housing.

10. The charging device according to claim 8 , wherein the gasket includes a contact surface having a heat-resistant coating.

11. The charging device according to claim 1 , wherein the gasket is a nickel-based alloy.

12. The charging device according to claim 11 , wherein the gasket is disposed in a radial recess in a flange of the bearing housing.

13. The charging device according to claim 2 , wherein the gasket is disposed in a radial recess in a flange of the bearing housing.

14. The charging device according to claim 2 , wherein the gasket is formed by at least two disc springs.

15. The charging device according to claim 3 wherein the disc spring is disposed at a contact point with the turbine housing and the bearing housing comprises rounded contact surfaces.

16. The charging device according to claim 5 , wherein the gasket includes a contact surface having a heat-resistant coating.

17. A charging device comprising:

a turbine housing; and

a bearing housing having a bearing arrangement for a shaft carrying a turbine wheel and a compressor wheel, a gasket arranged by metal-to-metal connection between a radially orientated flat surface of the turbine housing and a radially orientated flat surface of the bearing housing, wherein the gasket is resilient and includes a contact surface having a heat-resistant coating.

18. The charging device according to claim 17 , wherein the gasket is a disc spring.

19. The charging device according to claim 18 , wherein the disc spring is disposed at a contact point with the turbine housing and the bearing housing comprises rounded contact surfaces.

20. A charging device comprising:

a turbine housing; and

a bearing housing having a bearing arrangement for a shaft carrying a turbine wheel and a compressor wheel, a gasket arranged by metal-to-metal connection between a radially orientated flat surface of the turbine housing and a radially orientated flat surface of the bearing housing, wherein the gasket is resilient;

wherein the gasket is disposed at a contact point with the turbine housing and the bearing housing comprises rounded contact surfaces.
