Definitions

  • the invention relates to a switchable rocker arm of a valve train of an internal combustion engine, with an outer lever which includes an inner lever with its arms, which components pivotally movable relative to each other on a common axis applied to a valve end and the inner lever at an underside at the valve end Plant for a gas exchange valve and at the other end has a complementary surface for storage on a head of a support element, wherein the outer and inner levers are selectively connectable via coupling means to achieve a large valve lift, with decoupling a small or 0-valve stroke can be displayed, at least the outer lever has on its upper side at least one contact surface for a lifting cam and wherein the system is bounded laterally by two projecting from the cam follower in the valve direction guide plates for the gas exchange valve.
  • the object of the invention is therefore to provide a switchable drag lever of the aforementioned type, in which the cited disadvantages are eliminated.
  • the guide tabs emanate from the underside of the outer lever.
  • these tabs should be integrally formed with the inner lever and their outer sides are aligned with outer surfaces of the arms of the outer lever.
  • the guide tabs may be formed on the outer lever as separate components and connected by a suitable connection method such as welding, joining, etc. with the outer lever.
  • the inner lever and thus the entire drag lever can be made narrower at least at the valve end.
  • less space is required, so that a subsequent installation in cramped cylinder head concepts is possible.
  • the total mass of the finger lever is lowered. The moment of inertia is reduced compared to previous versions.
  • lever parts can be produced by punching and bending, for example, from sheet steel / steel strip, wherein the projecting guide straps can be punched out or bent in one operation.
  • the axis with stumps at both ends protrudes beyond the outer surfaces of the arms of the outer lever and that exactly at this projecting area at least one Lost Motion spring as a torsion leg spring in per se known Way is applied.
  • This may be another contribution towards “narrowing" the rocker arm on its valve side (as compared to incorporating the lost-motion springs about the axis between outer surfaces of the inner lever and inner sides of the arms of the outer lever or generally within the arms of the outer lever).
  • the contact surfaces for the Qundnocken on the outer lever are formed as projecting from the upper sides to the outside collar, which thus represent a sliding surface as a contact partner.
  • a roll can be applied here in each case.
  • the inner lever may have a role as a contact surface.
  • a sliding surface can also be applied here.
  • outer lever box-like so that it is connected by a respective double-ended crossbar.
  • This training has advantages in terms of stiffness and stability of the outer lever.
  • the arms of the outer lever in the region of the other end (support element side) are connected by a cross bar, this can be attacked for the coupling case of a longitudinally extending from the inner lever slide as a coupling agent.
  • This slide extends above the complementary surface of the inner lever for the support element.
  • the rocker arms parts or at least one of the arms (possibly except for an insert with the complementary surface) of the drag lever can also be made by casting.
  • a lightweight material such as plastic, which is optionally fiber or particle reinforced.
  • a particularly narrow-built rocker arm is present when dispensed to the aforementioned collar, which protrude from the top of the arms, and thus only the width of the top of the arms is used as Nockenanlauf phenomenon.
  • a switchable drag lever 1 of a valve train of an internal combustion engine This consists of a box-like outer lever 2 with two arms 3.
  • the arms 3 are connected at a valve-side end 5 and at an opposite other end 9 by a respective cross bow 17, 18.
  • the outer lever 2 includes an inner lever 4, wherein both levers 2, 4 are pivotally movable relative to each other. For this purpose, they run on an axis 6, which is applied approximately in the area above a gas exchange valve 8a.
  • the axis 6 projects beyond each with a stump 15 outer surfaces 14 of the arms 3 of the outer lever 2. Exactly in this area, each stump 15 can be surrounded by a torsion leg spring o. The like.
  • the inner lever 4 has in the region of the valve-side end 5 on a lower side 7 a system 8 for the gas exchange valve 8a.
  • a dome-shaped here complementary surface 10 for storage on a head of a support element.
  • This complementary surface 10 may be provided in the inner lever 4 is a hydraulically displaceable in at least one direction slide as coupling means.
  • the inner lever 4 has a role as a contact surface 19 for a low-lift cams. This is flanked on both sides by sliding surfaces as contact surfaces 11 on upper sides 10a of the arms 3 of the outer lever 2.
  • the contact surfaces 11 are formed as outwardly projecting, thin-walled longitudinal collar, which are preferably integrally connected to the outer lever 2. Run against these contact surfaces 11 respectively petitionhubnocken.
  • the outer surfaces 14 of the arms 3 of the outer lever 2 are stepped. In the area of the valve-side end 5, they have their smallest thickness. Behind the axis 6, viewed in the direction of the other end 9, the outer surfaces 14 thicken each via a step 16. As out FIG. 2 closer, the respective step 16 encloses the corresponding stump 15 half-shell similar with a small distance.
