Abstract

A flywheel housing assembly for an internal combustion engine includes a flywheel housing for accommodating a flywheel. The flywheel housing is configured to connect with a part of the internal combustion engine, the flywheel housing further having an outer side region intended to face an oil pan of the internal combustion engine, wherein the outer side region comprises a through hole and a vibration absorbing material portion arranged to seal the through hole.

First claim

The invention claimed is:

1. A flywheel housing assembly for an internal combustion engine, said flywheel housing assembly comprising a flywheel housing for accommodating a flywheel, the flywheel housing being configured to connect with a part of the internal combustion engine, the flywheel housing further having a solid outer side region intended to face an oil pan of the internal combustion engine, wherein the solid outer side region comprises a through hole and a vibration absorbing material portion arranged to seal the through hole.

2. Flywheel housing assembly according to claim 1 , wherein the through hole and the vibration absorbing material portion are complementary in shape.

3. Flywheel housing assembly according to claim 2 , wherein the vibration absorbing material portion is arranged inside the through hole.

4. Flywheel housing assembly according to claim 1 , wherein the vibration absorbing material portion is securely attached to the solid outer side region.

5. Flywheel housing assembly according to claim 1 , wherein the vibration absorbing material portion is a plate-shaped material portion.

6. Flywheel housing assembly according to claim 1 , wherein the vibration absorbing material portion is made by an elastic material.

7. Flywheel housing assembly according to claim 6 , wherein the elastic material is rubber.

8. Flywheel housing assembly according to claim 1 , wherein the solid outer side region is part of a longitudinal end portion of the flywheel housing.

9. Flywheel housing assembly according to claim 1 , wherein the flywheel housing comprises a connection portion configured to connect the flywheel housing to the ICE, and wherein the solid outer side region is further arranged spaced apart from the connection portion.

10. An internal combustion engine (“ICE”) system, comprising an ICE and a flywheel housing assembly according to claim 1 , wherein the solid outer side region is arranged with a distance from the oil pan so as to form a gap therebetween.

11. ICE system according to claim 10 , wherein the solid outer side region is arranged to face the oil pan such that the through hole and the vibration absorbing material portion being located along a vertical side of the flywheel housing.

12. A vehicle comprising a flywheel housing assembly according to claim 1 .

13. A method for producing a flywheel housing assembly according to claim 1 , comprising: providing a flywheel housing for accommodating a flywheel, the flywheel housing having the solid outer side region intended to face an oil pan of the internal combustion engine; forming the through hole at a solid portion of the outer side region; and arranging a vibration absorbing material portion at the through hole, such that the vibration absorbing material portion is arranged to seal the through hole.
