Definitions
- the invention relates to a valve train of an internal combustion engine.
- a valve train of an internal combustion engine is generally known for example from DE 37 11 436 C1.
- the valve train includes one Valve stem seal, a valve spring plate and a valve spring, which are used for Simplification of assembly are mechanically jammed together.
- For The production of the mechanical clamp connections is a special one Design of the parts to be clamped together, both the valve stem seal as well as the valve spring plate each in axial Direction extending extensions that interlock and thereby form a preassembled unit. The unity is just before and during its assembly with the other components of the valve train jammed.
- the invention has for its object a valve train of the input to further develop the type mentioned in such a way that assembly is further simplified is that the components forming the valve train are each simple and thereby have an inexpensive structure and that the Valve stem seal, the valve spring plate and the valve spring each without structural changes and / or without additional fastening devices can be assembled into the pre-assembled unit.
- valve train of an internal combustion engine comprising a valve stem seal, a valve spring plate and a valve spring, each of which is guided in a valve stem guide enclose the circumference and only before and during their assembly with the Valve stem guide and the valve to the valve train a pre-assembled unit form, the components of the unit being adhesively bonded.
- valve spring retainer and the valve spring to the pre-assembled unit becomes a simple and Achieved inexpensive construction of the valve train. Because the Components of the unit glued together are additional Fastening devices, such as in the axial direction extending protrusions that additionally on the components of the unit would be dispensable.
- the components of the unit are compared to conventionally used valve stem seals, Valve spring plates or valve springs, each separate from the valve train be completed, not changed. There is therefore the possibility without constructive changes to existing valve train components pre-assembled unit by gluing the components together to manufacture.
- the valve train is installed, for example, in such a way that in one first process step the valve stem seal, the valve spring plate and the Valve spring through an adhesive connection to the pre-assembled unit be connected to the pre-assembled unit in a second Process step essentially concentric to the valve stem guide a cylinder head of the internal combustion engine is positioned that the Valve in a third step through the valve stem guide and Unit is carried out in a fourth process step under compression the valve spring of the valve spring plate on the valve stem by means of valve cone pieces is attached and that in a fifth step the camshaft Actuation of the valve is mounted in the cylinder head.
- the valve stem seal is preferably made of an elastomeric material, encloses the valve stem of the valve with at least one sealing lip and preferably has a support body made of a tough, hard material.
- the Support body preferably consists of a deep-drawn metal part and can be designed such that it is the abutment for the end face of the valve spring forms, which faces the valve plate. The advantage here is that a Relative movement between this end face of the valve spring and the Cylinder head is omitted. Even cylinder heads made of light metal can do this come into use, and yet the Cylinder head surface excluded by the valve spring.
- the support body preferably consists of a deep-drawn metal part. On Sheet steel has proven itself particularly well for these applications.
- the adhesive bond is preferably formed by an adhesive, wherein as an adhesive commercially available adhesive for connecting metallic materials Application.
- an adhesive commercially available adhesive for connecting metallic materials Application.
- the surfaces of Need support body of the valve stem seal, valve spring and valve spring plate not to be coated with adhesive over the entire surface, since the adhesive bond only needs to exist before and during assembly and during the Operation of the internal combustion engine should solve. Due to the only selective applied glue is saved glue, so that the production of the preassembled unit is cheaper overall.
- the unit is preferably formed such that the valve spring on the Valve plate of the end facing away from the valve with the valve spring plate and on the end facing the valve plate with the support body of the Valve stem seal is glued. This will pre-assemble the unit and held together during assembly.
- FIG. 1 and 2 is a section of the valve train Internal combustion engine shown, wherein in this embodiment Rocker arm 14 for actuating valve 5 in the direction of movement 15 is provided.
- the valve 5 is guided in the valve stem guide 4, the Valve stem guide 4 in the cylinder head 16 of the internal combustion engine is pressed.
- the pre-assembled unit 6 consists of the valve stem seal 1, the Valve spring plate 2 and the valve spring 3, the valve spring 3 in the area their end faces 12, 13 with the axially adjacent components, the Valve stem seal 1 and the valve spring plate 2 only before and during the Assembly is adhesively connected.
- the adhesive connection is made by the Adhesive 10, wherein the gluing during the intended Use of the valve train releases as soon as valve 5 is actuated for the first time becomes.
- the preassembled unit 6 is thereby held in its installed position, that the support body 9 of the valve stem seal 1 the outer circumference of the Valve stem guide 4 encloses.
- the valve stem seal 1 has a sealing lip 8 made of elastomeric material on, the valve stem 7 of the valve sealing under elastic bias encloses.
- the valve stem seal 1 prevents lubricant on Valve stem 7 along, between the valve stem guide 4 and the Valve stem 7 into the combustion chamber of the internal combustion engine arrived and burned there.
- the sealing lip 8 of the valve stem seal 1 is provided with a support body 9 connected, which consists of deep-drawn sheet metal.
- the support body 9 has the axially facing the valve plate 11 a in the radial direction extending flange projection 17, which the end face 13 of the valve spring 3rd engages in the radial direction. Direct contact between the Valve spring 3 and the existing, for example, of light metal This excludes cylinder head 16.
- valve spring 3 On the side axially facing away from the valve plate 11, the valve spring 3 is on Valve spring plate 2 supported by two valve cone pieces 18, 19 with the Valve stem 7 is connected.
- the valve train is installed in a first Process step the valve stem seal 1, the valve spring plate 2 and the Valve spring 3 connected by adhesive 10 to preassembled unit 6 be that the pre-assembled unit 6 in a second step essentially concentric with the valve stem guide 4 on a cylinder head 16 the internal combustion engine is positioned that the valve 5 in one third step through the valve stem guide 4 and the unit 6 is carried out that in a fourth process step with compression of the Valve spring 3 of the valve spring plate 2 on the valve stem 7 by means of Valve plug pieces 18,19 is attached and that in a fifth Process step the camshaft for actuating valve 5 in the cylinder head 16 is mounted.
- valve plate 11 facing away End face 12 of the valve spring 3 with the valve spring plate 2 and the Valve plate 11 facing end face 13 of the valve spring 3 with the support body 9 of the valve stem seal 1 is glued.
