Abstract

A hood module for attachment on a cylinder head of an internal combustion engine may include a hood body comprised of plastic and a bearing bracket comprised of metal as a rotatable holder for a camshaft in the hood module. The bearing bracket may be attached to the hood body with position accuracy by a joint connection so that the bearing bracket is aligned for attachment on the cylinder head through the hood body. In some examples, a joint element in the form of a sleeve may be used as part of the joint connection between the bearing bracket and the hood body.”

First claim

1 .- 13 . (canceled)

14 . A hood module for attachment on a cylinder head of an internal combustion engine, the hood module comprising:
a hood body comprised of plastic; and a bearing bracket comprised of metal for holding a camshaft in a rotatable manner, wherein the bearing bracket is connected to the hood body by a joint connection so that the bearing bracket is aligned by the hood body for attachment on the cylinder head of the internal combustion engine.

15 . The hood module of claim 14 wherein the bearing bracket is connected to the hood body with position accuracy by the joint connection.

16 . The hood module of claim 14 wherein the joint connection between the bearing bracket and the hood body comprises at least two joint locations.

17 . The hood module of claim 14 wherein the joint connection is formed by at least one joint element.

18 . The hood module of claim 17 wherein the at least one joint element comprises a sleeve that is glued into or pressed into at least one of the bearing bracket or the hood body.

19 . The hood module of claim 17 wherein the at least one joint element is configured to form a melting zone in the plastic of the hood body or in an auxiliary element.

20 . The hood module of claim 14 further comprising at least two mounting holes disposed in at least one of the hood body or the bearing bracket, wherein each of the at least two mounting holes is configured to receive a fastener for fastening the hood module to the cylinder head.

21 . The hood module of claim 14 wherein the joint connection is formed by a joint element that comprises a sleeve, the hood module further comprising at least two mounting holes disposed in at least one of the hood body or the bearing bracket, wherein each of the at least two mounting holes is configured to receive a fastener for fastening the hood module to the cylinder head, wherein the joint element is aligned with one of the at least two mounting holes.

22 . The hood module of claim 21 wherein the sleeve forms a part of one of the at least two mounting holes.

23 . The hood module of claim 14 wherein the joint connection is formed by at least one joint element, wherein the at least one joint element and the bearing bracket comprise a single piece.

24 . The hood module of claim 14 wherein the joint connection is formed by at least one joint element, wherein the at least one joint element is formed in one piece with the bearing bracket and with the hood module in a casting process.

25 . The hood module of claim 14 wherein the bearing bracket is configured to hold the camshaft, wherein the bearing bracket includes a bearing ring that is inserted in a fitting aperture in the bearing bracket and is used as a rotatable holder for the camshaft.

26 . A method of forming a hood module for attachment on a cylinder head of an internal combustion engine, the method comprising:
providing a hood body comprised of plastic and a bearing bracket comprised of metal for holding a camshaft in a rotatable manner; aligning the bearing bracket on the hood body; joining the bearing bracket to the hood body using a joint connection so that the bearing bracket is aligned for arrangement on the cylinder head of the internal combustion engine.

27 . The method of claim 26 wherein the bearing bracket is joined to the hood body with position accuracy so that the bearing bracket is aligned for arrangement on the cylinder head of the internal combustion engine.

28 . The method of claim 26 further comprising:
providing a plurality of bearing brackets;
aligning the plurality of bearing brackets with one another and on the hood body; and
joining the plurality of bearing brackets to the hood body using joint connections.

29 . The method of claim 26 further comprising providing a joint element for formation of the joint connection between the bearing bracket and the hood body.

30 . The method of claim 29 further comprising:
heating the joint element;
heating a region near the joint connection so as to form a melting zone in the plastic of the hood body or in an auxiliary element; and
fitting the joint element to the melting zone in the hood body or the auxiliary element.

31 . The method of claim 29 wherein a joint location and the joint element are heated so that the joint element is brought into contact with the joint location to form a melting zone in the plastic material of the hood body or in an auxiliary element, wherein the joint element is fitted in or to the melting zone.
