Definitions
- the invention relates to a rocker arm of a valve train of an internal combustion engine with two connected by a transverse section side walls, wherein a) either at an underside of the transverse section at one end only a complementary Einformu ⁇ g for a head of a support element runs or b) at an underside of the transverse section on a End on the one hand a complementary indentation for a head of a support element and in addition to the one end a receptacle for coupling means for selectively coupling the drag lever with another lever to achieve different cam lifts is applied.
- Such a drag lever is apparent for the case b) from DE 101 58 703 A1. This is designed here as an external lever of a switchable lever system to achieve different cam strokes.
- the object of the invention is therefore to provide a drag lever of the aforementioned type, in which the cited disadvantages are eliminated.
- this object is achieved by the features of the characterizing part of claim 1, wherein in case a) the end is formed with the indentation as a separate component or which in case b) either only one of the sections end with the indentation / recording for coupling agent or both Sections are formed in a structural unit as a separate component or are.
- the component formed separately according to the invention can either be installed in a "classic" drag lever on one end, which preferably consists of sheet metal or in a drag lever, which is part of a schaltba- lever system and is also preferably made of sheet metal.
- this component can have the indentation for the head of the support element and at the same time the receptacle for the preferred longitudinal displacement of coupling means.
- the drag lever is made of sheet metal, preferably processed by forming technology.
- a massively transformed rocker arm which is desired in any case a lightweight construction.
- a U-shaped or H-shaped design of the finger lever is not required in each case.
- the drag lever may also have only a bar-shaped geometry.
- other materials such as cast iron, plastics, fiber-reinforced plastics, etc. will also be available to the person skilled in the art at this point in order to form the rocker arm.
- Another subclaim relates to appropriate connection method of the separate component with the cam follower.
- measures as clinching, caulking, welding, etc. are intended.
- the receptacle for the coupling means extend longitudinally.
- included with the scope of the invention is also a Solution with two only laterally adjacent levers, which can be selectively connected via a then transversely extending recording with coupling means.
- Another subclaim relates to a simple manufacturing method for the separate component. Here again is thought to sheet metal or massive forming.
- Figure 1 in a three-dimensional view of the drag lever as part of a switchable drag lever system
- FIG. 2 shows a longitudinal section along a longitudinal central axis through the drag lever according to FIG. 1.
- Figure 1 discloses a drag lever 1 with side walls 3, 4, which are interconnected by a lower transverse section 2.
- the drag lever 1 is installed in a longitudinal recess 13 of a further lever 9 and connected in the region of an end 11 with this articulated.
- the drag lever 1 with lever 9 thus forms a switchable drag lever system, which need not be explained in detail at this point.
- a dome-shaped here complementary indentation 7 for support on a head of a supporting element.
- the indentation 7 are formed together with the receptacle 8 in a structural unit as a separate component.
- this component is connected to the drag lever 1 by means of welding technology, wherein the latter has a connecting surface or recess 10 extending orthogonally to its longitudinal extent for this purpose.
- the manufacturing costs for such a finger follower are relatively low. This is especially true when the drag lever 1 (preferably also with the other lever 9) is made from a sheet metal forming material.
- the separate component with the indentation 7 and the receptacle 8 should also be produced in a sheet metal forming process such as deep drawing or in a massive forming process such as extruding.
