Definitions
- the invention relates to a rocker arm of a valve train of an internal combustion engine, which can be switched to different strokes for at least one gas exchange valve, with an outer lever and an inner lever extending between its arms, both levers being pivotable relative to one another and coupled with one another via coupling means, so that at Coupling generates a large and, when decoupled, a small or O-valve stroke, whereby on one underside of the rocker arm a system for a gas exchange valve is applied at one end and a complementary surface for a support element at the other end, and at least one counter surface on an upper side of the outer lever for a large stroke and a counter surface for a small or O-lifting cam is provided on an upper side of the inner lever.
- rocker arm is already known from DE 27 53 197 A 1, which is considered to be generic.
- a pawl is provided as the coupling means, which engages below the inner lever and is connected via an elaborate linkage.
- the pawl disadvantageously increases the overall height of the switchable rocker arm.
- the external application via the linkage proves to be relatively expensive.
- sliding surfaces are provided as counter surfaces on the upper sides of the rocker arm. Because of these sliding surfaces, the friction work is increased
- the object of the invention is therefore to provide a compact rocker arm of the aforementioned type, in which the disadvantages cited are eliminated with simple means
- this object is achieved in that the levers have approximately the same length and do not protrude essentially at the end, the inner lever having the contact and the complementary surface and projecting above its contact with a transverse axis, on each transverse axis one Arm of the outer lever is pivotally mounted, the coupling means positioned in the area above the complementary surface in the inner lever and for the coupling case with at least one relative position of the are displaceable transversely to one another in such a way that they run in sections in a recess in the outer lever and a crossbar connecting them emerges from the arms of the outer lever.
- the arms of the outer lever are held over the crossbar, at least before final assembly.
- a simple end stop for the outer lever is realized by a decoupling movement in the direction of the cam base circle back on the inner lever, so that the coupling means can assume their coupling position after the stop and if desired.
- At least one counter surface of the outer lever can be contacted by a large lift cam.
- only a slide can be provided as a coupling means in the area of the complementary surface of the inner element, which is displaced axially outwards.
- two slides arranged in the inner element as coupling means, which can be moved axially outwards for coupling purposes.
- the aforementioned crossbar can also be arranged on another length section of the outer lever and can also be designed such that it only holds the arms of the outer lever, in which case stops can be provided in some other way. It is particularly advantageous to provide the crossbar in one piece with the outer lever. However, it is also conceivable to form the arms of the outer lever separately and then to connect them via a crossbar, for example welded on.
- all of the mating surfaces or only the mating surfaces of the outer lever can also be provided with rollers.
- At least one torsion spring is preferably provided as the lost motion spring, which, owing to its compactness, can be excellently adapted in the finger lever according to the invention.
- the torsion spring should enclose the transverse axis and act with its corresponding leg on the outer lever in the cam direction. Depending on the application, several torsion springs can also be applied.
- the slides can be present as coupling means locked or unlocked without pressure.
- the hydraulic fluid pressure in the opposite direction the slide should be displaceable via compression spring force.
- a displacement in both directions via hydraulic means or another suitable servo device is also conceivable.
- the slide should preferably have piston-like geometry are pawls and similar coupling members enclosed by the protection area, wherein instead of the bore for the slide, cross-section-like cross-sections etc. are also conceivable, which are preferably complementary to the slide
- the levers from a lightweight construction material, such as sheet metal.
- a lightweight construction material such as sheet metal.
- FIG. 1 in a spatial view according to the invention
- FIG. 2 shows a bottom view of the rocker arm according to FIG. 1,
- Fig. 3 is a plan view of the rocker arm of Figure 1 and the
- Figure 1 discloses a switchable rocker arm 1 This consists of two parallel arms 3 a, 3 b, which form an outer lever 2. On their underside 7, the arms 3 a, 3 b are connected via a crossbar 16
- An inner lever 5 runs between the arms 3 a, 3 b, approximately with the same length.
- the outer lever 2 experiences a stop on the inner lever 5 in the cam direction via the crossbeam 16.
- the inner lever 5 (see also FIG. 2) has one at one end System 8 for acting on a gas exchange valve At the opposite end a complementary surface 9 for a head of a support element is produced in the bottom 7 in the form of a spherical cap.
- the rocker arm 1 is mounted on the aforementioned head via the complementary surface 9.
- Top surfaces 10 a, 10 b of the arms 3 a, 3 b are produced according to FIG. 1 with counter-running surfaces 11 a, 11 b designed as sliding surfaces for large-lift cams.
- the inner lever 5, on the other hand, has a rotatable roller on its top 12 as counter-running surface 13 here a low-lift or 0-stroke cam can be considered
- a transverse axis 14 extends in the area of the system 8. This goes directly through a bore in the inner lever 5 approximately above the system 8 (different configurations are also conceivable) between the arms 3 a, 3 b and the inner lever 5 there is still enough space in this area on the transverse axis 14 to arrange two torsion springs 17 a, 17 b. These each engage with one arm 18 a, 18 b of the corresponding arm 3 a, 3 b of the External lever 2 and act as lost motion springs For special applications However, helical compression springs or the like are also conceivable and provided.
- a transverse bore 27 is applied in the inner lever 5 (see in particular FIGS. 4, 5).
- two opposing coupling means 6 a, 6 b (FIG. 4) and 6 c, 6 d (FIG. 5) run completely in this bore 27 and are designed as piston-like slides.
- the slide 6 a, 6 b are shifted according to Figure 4 in their coupling direction via hydraulic fluid. This can be guided from the head of the support element (not shown in the drawing) and further through a feed 33 arranged in the inner lever 5 directly in front of end faces 22 a, 22 b of the corresponding slide 6 a, 6 b. If there is a sufficiently high pressure of hydraulic medium, the slides 6 a, 6 b are shifted in sections into a corresponding recess 15 a, 15 b of the opposite arm 3 a, 3 b.
- the slide 6 c, 6 d is displaced in their coupling direction via the force of at least one compression spring 30.
- a relocation takes place here via hydraulic medium, which in turn can be conducted from the head of the support element via the complementary surface 9 through the inner lever 5 in front of outer end surfaces 29 a, 29 b of the slide 6 c, 6 d.
- the cutouts 15 a, 15 b for the coupling means 6 do not necessarily have to consist of a bore. According to this, it is provided that a finger-like extension 21 a, 21 b of the upper sides 10 a, 10 b Provide arms 3 a, 3 b at the end of the support element. These have on their underside 20 a, 20 b corresponding cutout segments 15 a, 15 b.
- the counter-running surfaces 11 a, 11 b of the arms 3 a, 3 b can also be provided with rollers.
- the counter-running surface 13 of the inner lever 5 is then designed as a sliding surface.
- a diameter of the rolls can be grouped.
- the coupling means 6 can be grouped or grouped using the outer lever 2.
