Definitions

  • a generic device for changing the timing of gas exchange valves of an internal combustion engine which is attached to the drive end of a camshaft mounted in the cylinder head of an internal combustion engine and is designed in principle as a hydraulic actuator that can be controlled as a function of various operating parameters of the internal combustion engine
  • This device essentially consists of a drive wheel which is in drive connection with the crankshaft of the internal combustion engine and an impeller which is connected in a rotationally fixed manner to the camshaft of the internal combustion engine, which are in power transmission connection with one another and transmit the torque of the crankshaft to the camshaft of the internal combustion engine.
  • the drive wheel has a hollow cylindrical peripheral wall and two side walls.
  • the impeller has on the circumference of its wheel hub five vanes which extend radially into the work spaces and which divide the work spaces into an A pressure chamber and a B pressure chamber, which, with optional or simultaneous pressurization with a hydraulic pressure medium, pivots or fixes the impeller against the drive wheel and thus the camshaft relative to the crankshaft.
  • the impeller can be mechanically coupled to the drive wheel by means of a separate locking element in a preferred base position within its adjustment range, in particular when the internal combustion engine is restarted until the required one is built up Pressure medium pressure to avoid a rattling of the impeller on the boundary walls of the drive wheel resulting from the alternating torques of the camshaft.
  • This locking element which is designed as a sleeve-like cylindrical pin, is arranged in a continuous axial bore in the wheel hub of the impeller and, by means of a spring element designed as a compression coil spring, which is supported on the one hand on the rear side of the locking element and on the other hand on a counterholder also inserted into the axial bore Locking position within a receptacle in the side wall of the drive wheel facing away from the camshaft.
  • the inclusion of the locking element is connected to one of the A pressure chambers of the device via a pressure medium feed groove incorporated into the side surface facing away from the inner side of the camshaft, so that when the A pressure chambers are pressurized, the locking element is hydraulically moved into an unlocking position within the axial bore in the wheel hub of the Impeller is movable.
  • a disadvantage of this known device is that the locking element for mechanically coupling the impeller to the drive wheel in its unlocked position also outside the base position of the impeller. gelrades via the pressure medium feed groove for receiving it in the side wall of the drive wheel is constantly in pressure medium connection with the corresponding A pressure chamber of the device, so that when the A pressure chambers are pressurized, the pressure medium pressure present and the pressure peaks of the pressure medium occurring also on the locking element or act on the entire locking mechanism.
  • the pressurized locking element is supported on its counter-holder arranged in the axial bore of the wheel hub, and the counter-holder, which is usually made of plastic, is supported on the side wall of the drive wheel that closes the axial bore, the pressure medium pressure permanently acting on the locking element leads through the constant rotation between the relative values Impeller and the drive wheel thus increased wear on the counter holder and on the side wall of the drive wheel.
  • this wear adversely affects the function of the locking mechanism and can lead to the failure of the function over the life of the device.
  • the invention is therefore based on the object of designing a device for changing the control times of gas exchange valves of an internal combustion engine, in particular a rotary piston adjusting device for adjusting the angle of rotation of a camshaft relative to a crankshaft, in which this results from the constant pressure medium connection of the locking element with one of the pressure chambers of the device or the adverse effects resulting from the permanent pressurization of the locking element on the entire locking mechanism can be avoided in a simple manner.
  • this object is achieved in a device according to the preamble of claim 1 such that within the pressure medium incorporated into the inner surface of the respective side wall of the drive wheel Feed groove a local lock is arranged through which the pressure medium supply for receiving the locking element is permanently interrupted when the impeller is pivoted out of the base position.
  • a bypass is additionally arranged in the side surface of the wheel hub of the impeller opposite the pressure medium supply groove in such a way that only when the impeller is pivoted into the base position can the local lock be bridged and a pressure medium supply for receiving the locking element is possible.
  • the locking element is designed in a known manner as a sleeve-like cylinder pin, which is arranged in a continuous axial bore in the wheel hub of the impeller and by a spring element designed as a compression coil spring, which is located on the one hand on the back of the locking element and on the other hand also in the axial bore supports the counterholder used, is displaceable in its locking position in the receptacle in one of the side walls of the drive wheel.
  • the receptacle of the locking element is accordingly also formed in a known manner as a local depression in the inner surface of the side wall opposite the locking element, which has a preferably square-shaped contour that is larger than the cross-sectional area of the locking element by a defined clearance and in which the preferably has an arcuate course Pressure medium supply groove opens.
  • the receptacle of the locking element designed in this way and its pressure medium supply groove are preferably arranged in the side wall facing away from the inner surface of the camshafts and are produced without cutting by stamping into this side wall, the local barrier in the pressure medium supply groove being preferred is formed as a material web remaining during embossing.
  • stamping it is also possible to produce the receptacle of the locking element and its pressure medium supply groove by milling into the corresponding side wall of the drive wheel, and also to form the local lock in the pressure medium supply groove as a remaining material web.
  • the bypass for the local lock in the pressure medium supply groove also in the side face of the wheel hub of the impeller facing away from the camshaft to be arranged and designed as an elongated hole-like depression. It has proven to be particularly advantageous to mold this slot-like depression in the usually powder-metallurgical manufacture of the wheel hub of the impeller into the corresponding side surface of the wheel hub, that is to say to design the press mold for the wheel hub of the impeller in such a way that no reworking of the bypass forming part is carried out Deepening are more necessary.
  • the slot-like depression forming the bypass is subsequently machined into the corresponding side surface by machining processes, such as milling the wheel hub of the impeller.

  • the hydraulic pressure medium When pressure is applied to those pressure chambers of the device, one of which is also connected to the pressure medium supply groove for receiving the locking element, such as when the internal combustion engine is restarted, the hydraulic pressure medium thus initially reaches the local lock in the pressure medium supply groove and then flows within the bypass in the wheel hub of the impeller over the local lock into the receptacle of the locking element and then shifts the locking element into its unlocked position within the axial bore in the wheel hub of the impeller.
  • the now unlocked impeller then pivots out of its base position due to the further pressurization of the pressure chambers, so that the bypass in its wheel hub also moves away from its bridging position to the local lock in the pressure medium supply groove and a further pressure medium supply for receiving the locking element by the is now interrupted at the local lock flat side surface of the wheel hub of the impeller.
