Definitions

  • the invention relates to a connecting rod for a variable compression internal combustion engine, and to a variable compression internal combustion engine having a connecting rod.
  • a high compression ratio has a positive effect on the efficiency of the internal combustion engine.
  • compression ratio is generally understood the ratio of the entire cylinder space before compression to the remaining cylinder space after compression.
  • the compression ratio may only be selected so high that a so-called "knocking" of the internal combustion engine is avoided during full load operation.
  • the compression ratio could be selected with higher values without "knocking" occurring.
  • the important part load range of an internal combustion engine can be improved if the compression ratio is variably adjustable.
  • systems with variable connecting rod length for example, are known, which actuate an adjusting device of a connecting rod with the aid of hydraulic changeover valves.
  • a generic switching valve is for example from the DE 10 2012 112 461 A1 refer to.
  • the switching valve is designed as a cartridge solution. This has the advantage that the changeover valve can be checked for leaks independently of the connecting rod arrangement in which the changeover valve is installed. The changeover valve is pressed into the connecting rod body.
  • An object of the invention is to provide an improved, and inexpensive connecting rod for a variable compression internal combustion engine, which is process reliable to manufacture.
  • Another object is to provide an internal combustion engine with variable compression with such a connecting rod.
  • a connecting rod for an internal combustion engine with variable compression with an adjusting device for adjusting an effective connecting rod length, wherein an adjustment of the adjusting device by means of a switching valve is adjustable.
  • a valve housing of the changeover valve is axially secured in a bore of the connecting rod.
  • the connecting rod comprises a Pleuel Sciences and a connecting rod cover arranged thereon, which enclose a Bublagerauge.
  • a connecting rod bearing eye can be arranged with the eccentric adjusting device.
  • As a connecting rod length the distance of a central axis of the Hublagerauges is defined to a central axis of the connecting rod bearing eye.
  • a press fit can be interpreted only with such a degree of excess as the structural mechanics of the connecting rod and the valve due to mounting voltages allowed.
  • the valves can rotate axially with weak press dressings and low friction.
  • the orientation of the switching valve in the bore can be of crucial importance for the operation of the valve, for example, if the tap of the valve is not arranged in the valve axis. This results in a conflict of objectives for the press dressing design: sufficient axial holding force, position fixation and low leakage against impermissibly high mounting voltage superimposed by operating voltages.
  • the valve housing of the changeover valve is axially secured in the bore of the connecting rod.
  • the valve housing can not loosen and move or rotate out of its intended position in the connecting rod body.
  • the upper limit of the press fit valve housing in the connecting rod body can be adapted to the maximum allowable mounting voltages and the lower limit shifted to an economical production.
  • the risk of axial displacement or rotation of the reversing valve in the connecting rod during engine operation can be advantageously reduced by means of the end-side axial securing of the valve housing in the connecting rod described here.
  • a simple axial securing can take place via a weld or weld points between the valve housing and connecting rod body or connecting rod cover.
  • an adhesive or an end coating, such as paint can be used as a backup.
  • the connecting rod may have one or more axial counterbores whose protrusions for axial securing of the changeover valve are formed in one or more end-side recesses of the valve housing.
  • This variant uses a countersink hole in the connecting rod and frontal cut-outs in the valve.
  • the countersink holes serve as a centering for a forming tool, for example, with a hard ball head, which presses the projection of the countersink hole in the cutout of the valve, so as to securely fix the valve axially and against rotation.
  • a countersink can be assigned to several cutouts of different valves.
  • the axial lock can be selected independently of the valve position in the connecting rod. Likewise, several milled or reshaping operations can be applied.
  • Countersink bores which are arranged in the connecting rod sufficiently close to the bore in the connecting rod for receiving the changeover valve, can be sufficiently thin Have wall thickness to the bore as a supernatant out, so that the material of these supernatants can be displaced by mechanical pressure to the bore. If the valve housing has end-side recesses at this point, then the material of the projections can be pushed into these recesses. As a result, a toothing between Pleuel stresses or Pleueldeckel and valve housing takes place. The valve housing is secured in this way in the bore against axial displacements. If the recesses in the valve housing are not circumferential but are arranged over a limited angular range, then the valve housing and thus the changeover valve can also be secured against rotation in the bore.
  • the valve housing may have axial countersink holes, the supernatants for axial securing of the changeover valve are formed into one or more end-side recesses of the connecting rod.
  • the counterbores can also be arranged in the valve and the frontal cut-outs in the connecting rod body.
  • the projections of the counterbores can be pressed by means of a forming tool in the recesses.
  • the material of the supernatants can be pressed into the recesses by exerting a mechanical pressure, as can be generated, for example, by means of a forming tool.
  • the connecting rod balls can be pressed into the countersink holes, whereby the supernatants are pressed into the recesses.
  • a variant of this technical solution is the injection of a ball in the countersink hole. The supernatant is so far deformed when pressing the ball in the countersink hole that an axial and Anti-rotation occurs, but also the ball is prevented from loosening.
  • the desired toothing between Pleuel stresses or connecting rod cover and valve housing can be achieved in a suitable manner.
  • conical or frusto-conical bodies could be pressed into the counterbores to achieve the desired effect.
  • the recesses may be provided as on a peripheral edge of the valve housing chamfer.
  • a simple embodiment of the recesses of the valve housing can be achieved in the form of a peripheral on the outer edge of the valve housing chamfer. This makes it possible to achieve axial securing of the reversing valve in the bore of the connecting rod. If the material of the supernatants with a suitable pressure in the chamfer and pressed against the valve housing, then it can also be used to secure against rotation of the valve housing in the bore.
  • the valve housing may have on at least one end face an axial projection, wherein for the axial securing of the changeover valve, the supernatant is fixed with a retaining ring.
  • Another variant of the frontal axial securing is in projecting valves, which are fixed by means of retaining rings in their axial position. DIN standard parts can also be used as circlips.
  • the retaining ring can be fixed to the valve via a fit, a weld, in a groove, a thread or a similar fixation possibility.
  • the valve housing may have on a first end face an axial shoulder and on a second end face an axial projection, wherein for the axial securing of the changeover valve, the supernatant is fixed with a retaining ring.
  • the valve may alternatively be provided with an axial shoulder on an end face, which comes to rest on the connecting rod or connecting rod cover and a locking ring on the axial projection of the second end face, as a counterhold on the other end face of the connecting rod for fixing the valve housing serves.
  • the circlip can be fixed to the valve via a fit, a weld, in a groove, a thread, or similar fixation capability.
  • the connecting rod of the circlip may be mounted on the supernatant by means of a press fit, a weld or a thread.
  • the securing ring can expediently be fixed to the valve via a fit, a weld, in a groove, a thread or a similar fixation possibility.
  • the connecting rod of the locking ring may have at least one rotation.
  • an additional anti-rotation of the locking ring can be secured against rotation, for example, as a ring with retaining tabs, which engage in a counterpart or both sides, executed.
  • the anti-rotation may comprise at least one of the locking ring radially outwardly standing tab, which is fixed to the connecting rod, in particular to the connecting rod cover.
  • the tab can be materially connected to the connecting rod, for example, be welded.
  • the tab can engage in a recess of the connecting rod.
  • the tab can engage in a recess of the connecting rod.
  • the valve housing may have on at least one end face an axial projection, wherein for the axial securing of the changeover valve, the supernatant is provided reshaped after the assembly of the valve housing.
