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.

Abstract

L'invention concerne un basculeur (1) d'un mécanisme de distribution d'un moteur à combustion interne, comprenant deux parois latérales (3, 4) reliées par une section transversale (2). A une extrémité (6) d'une face inférieure (5) de cette section transversale (2) est ménagée une cavité sphérique (7) conçue pour loger, par accouplement complémentaire, une tête d'un élément d'appui, et au niveau de cette même extrémité (6) est disposé un logement (8) destiné à des moyens d'accouplement (8a) pour accoupler sélectivement ledit basculeur (1) avec un levier (9) supplémentaire afin d'obtenir différentes levées de came. Selon l'invention, ces deux sections (7, 8) sont configurées en tant que composant distinct sous la forme d'une unité structurale, ce qui présente des avantages en termes de production, en particulier lorsque le basculeur (1) et le levier supplémentaire (9) sont constitués de tôle.
