Abstract

A cam carrier module for vehicles may include a cam carrier coupled with a cylinder head, an injector penetrating through the cam carrier and the cylinder head, and a sealing device provided between the cam carrier and the cylinder head and enclosing the injector to implement sealing of the injector.

First claim

What is claimed is:

1. A cam carrier module for vehicles, comprising:
a cam carrier coupled with a cylinder head;
an injector penetrating through the cam carrier and the cylinder head;
a sealing device provided between the cam carrier and the cylinder head and enclosing the injector to implement sealing of the injector, wherein the sealing device includes:
an injector fixed part provided at a middle of the cam carrier, having a bottom surface adhered to the cylinder head and provided with an injector hole through which the injector is inserted;
a sealing groove formed on the bottom surface of the injector fixed part and enclosing the injector hole; and
a gasket provided in the sealing groove and made of an elastic material sealing between the cam carrier and the cylinder head; and

a detection groove provided on the bottom surface of the injector fixed part and having a first end connected to a portion of the sealing groove and a second end configured to open toward a side of the injector fixed part.

2. The cam carrier module of claim 1 , wherein the gasket is configured to protrude to an outside of the sealing groove to adhere the cylinder head.

3. The cam carrier module of claim 1 ,
wherein an edge part is provided to form an edge of the cam carrier,
wherein a bottom surface of the edge part and a top surface of the cylinder head are bonded by a sealing adhesive, and
wherein a width of the bottom surface of the edge part is narrower than a width of the top surface of the cylinder head to form a bonding band by the sealing adhesive along a line at which a side of the edge part meets the top surface of the cylinder head.

4. The cam carrier module of claim 3 , wherein the bonding band is configured to be formed by squeezing out a portion of the sealing adhesive applied between the cylinder head and the edge part when the top surface of the cylinder head is bonded with the bottom surface of the edge part.

5. The cam carrier module of claim 3 , wherein all of a top surface and the bottom surface of the edge part and the top surface of the cylinder head and a bottom surface of the cylinder head cover which adheres thereto have a flat shape.

6. The cam carrier module of claim 1 , wherein a plurality of journal parts each is configured to enclose a cam shaft so that the cam shaft is provided along a length direction of the cam carrier and the journal parts are integrally formed.

7. The cam carrier module of claim 6 , further comprising:
a first oil channel formed in the cylinder head and having a first end connected to a main gallery at a cylinder head side and a second end connected to the top surface of the cylinder head; and
a second oil channel formed in the cam carrier and having a first end connected to the second end of the first oil channel and a second end connected to an inner surface of a journal forming each journal part.

8. The cam carrier module of claim 7 , wherein the first end of the first oil channel and the main gallery at the cylinder head side are each connected to a cylinder head fastening bolt hole for fastening between the cylinder head and a cylinder block to facilitate oil flow.

9. The cam carrier module of claim 7 , wherein a bottom surface of the cam carrier is provided with a recess and the first end of the second oil channel and the second end of the first oil channel are connected to the recess to facilitate the oil flow.

10. The cam carrier module of claim 9 , wherein the recess is formed at an end of a cam carrier fastening bolt hole for fastening between the cam carrier and the cylinder head.

11. The cam carrier module of claim 7 , wherein the journal part adjacently disposed to a sprocket operated together with a crank shaft among the journal parts is provided with a rolling bearing to enable the cam shaft to perform a rolling friction.
