Definitions

  • the invention relates to a valve train for a cylinder head of an internal combustion engine with the features of the preamble of patent claim 1.
  • sliding cams is from the German disclosure document EN 10 2005 006 489 A1 known. It is a camshaft arrangement that has a base shaft and cam carriers arranged on it that are axially displaceable but held in a rotationally fixed manner. Cams with several cam curves are formed on the cam carriers, each of which has a common base circle and different cam curves that have different curve profiles. The cams actuate valve actuating means of associated cylinders. Actuators are provided for carrying out switching processes, whereby during the switching processes, another of the cam curves of the cam comes into contact with the valve actuating means by axially displacing cam carriers on the base shaft.
  • valve train for an internal combustion engine is known.
  • This valve train comprises a camshaft with a sliding cam device, which has adjacent cam tracks acting on valves with different cam shapes and lifting curves, which lifting curves work together with actuating elements having control pins for adjusting the sliding cam device.
  • a valve train for a cylinder head of an internal combustion engine is known, with a first camshaft rotatably mounted in a first and a second camshaft bearing, with at least one cam with a first cam curve and a second cam curve that is different from the first cam curve.
  • a gas exchange valve can be actuated with the first or the second cam curve, wherein a camshaft section is provided with which the cam can be displaced via an adjusting means such that the gas exchange valve can be actuated via either the first or the second cam curve.
  • the first camshaft and the cam have a fixed position relative to one another and the first camshaft can be axially displaced in the first and the second camshaft bearing, wherein an axial lock is provided for the camshaft.
  • German Disclosure Document EN 10 2015 012 287 A1 the international patent application WO 2012/079794 A1 , the US patent application US 2016/0090921 A1 and the German Disclosure Document EN 10 2007 061 353 A1 deal with axially sliding camshafts.
  • valve trains A disadvantage of the above-mentioned valve trains is their axial locking mechanisms, which are susceptible to wear.
  • the object of the present invention is to avoid the above-mentioned disadvantage.
  • a further object of the present invention is to prevent axial displacement of the camshaft during operation of the internal combustion engine.
  • the proposed axial locking mechanism can minimize the relative movement of the camshaft to the actuating means that occurs when the internal combustion engine is operating.
  • a particular advantage is that the axial locking mechanism is a guide rail that runs radially around the camshaft with a first and a second guide rail that are axially adjacent to one another and into which a locking element pre-tensioned by a spring element engages. Simple switching of the switching camshaft with simultaneous locking in the end positions is possible because the first and second guide rails are spaced apart from one another by a cylindrical section.
  • the angular range according to claim 2 is a particularly preferred angular range.
  • Figure 1 shows a top view of a valve train 1 according to the invention for a cylinder head of an internal combustion engine.
  • the cylinder head which is not numbered, is shown without a valve cover so that the valve train 1 is visible.
  • the valve train 1 is arranged on the inlet side and is designed for two cylinders with four equally acting, Fig.2 shown gas exchange valves are provided.
  • the valve train 1 has a first camshaft 4 which is rotatably mounted in a first and a second camshaft bearing 2, 3 and further camshaft bearings which are not numbered.
  • a second camshaft which is not numbered is provided on the exhaust side.
  • the first camshaft 4 has four cams 5 for four gas exchange valves (not shown) for two cylinders of the internal combustion engine, with only one cam 5 being numbered.
  • the cam 5 has a first cam curve 6 and a second cam curve 7 which is different from the first cam curve 6.
  • the gas exchange valve can be actuated by either the first or the second cam curve 6, 7 via an intermediate element, such as a sliding rocker arm.
  • a camshaft section 8 is provided, with radially outwardly encircling control grooves into which an invisible pin of an actuating means 9 engages, so that the camshaft 4 with the cam 5 can be displaced in such a way that the gas exchange valve can be actuated either via the first or the second cam curve 6, 7.
  • the camshaft 4 and the cam 5 are preferably made of the same material and are one piece. In a further embodiment, the cam can also be shrunk or joined onto the camshaft 4.
  • a spur gear 17 is provided to drive the camshaft 4, which can be driven by another, unnumbered gear.
  • an axial locking device 10 shown in the following figures is provided for the axially displaceable camshaft 4.
  • FIG 2 shows a top view of the axial locking device 10 for the first camshaft 4.
  • the first camshaft 4 has Figure 2 two cams 5, whereby only one cam 5 is numbered.
  • Gas exchange valves 19 can also be seen, each with a valve spring 20, of which only one is numbered.
  • a drive gear, the spur gear, for the camshaft 4 is again numbered 17.
  • the axial locking 10 is a Figure 4 shown radially encircling the camshaft 4 with a first and a second, axially adjacent guide track 12, 13, into which a locking element 15 pre-tensioned by a spring element 14 engages.
  • the locking element 15 pre-tensioned by the spring element 14 is arranged in a bracket 21.
  • the axial locking 10 is mounted on the first camshaft 4 with a screw connection 18.
  • Figure 3 shows a section through the bracket 21 with the locking element 15 pre-tensioned by the spring element 14.
  • the bracket 21 has two fastening holes 23.
  • the locking element 15 is a pin pre-tensioned by the spring 14, the pre-tension being adjustable by a cap nut 22.
  • Figure 4 shows a section through the axial locking mechanism 10 without the pre-tensioned locking element 15.
  • the guide 11 with the first and second axially adjacent guide tracks 12, 13 is mounted radially on the camshaft 4 in the present exemplary embodiment via a roller bearing 25, in the present exemplary embodiment a ball bearing. In another exemplary embodiment, it can also be a plain bearing.
  • a camshaft axis is numbered 16.
  • An angle between the second guide track 13 and the camshaft axis 16 is designated ⁇ .
  • the first and second guide tracks 12, 13 are axially spaced from one another by a cylindrical section 24.
  • the first and second guide tracks 12, 13 form an angle of between 2° and 45° with the camshaft axis 16.
  • Figure 5 shows a section through the locking element 15 and the guide 11.
  • the preload by the spring element 14 is shown by an arrow on the locking element 15 in the direction of the guide 11.
  • a displacement path of the locking element 15 over the guide 11 is numbered 26.
  • This displacement path 26 corresponds to the width of a cam curve 6, 7.
  • An angle between the guide tracks 12, 13 is numbered ⁇ .
  • the guide 11 has an axial groove via the guide tracks 12, 13 and the cylindrical section 24, in which the locking element 15 is axially displaceable.
