Definitions

  • the invention relates to a camshaft adjuster.
  • Camshaft adjusters are used in internal combustion engines for varying the timing of the combustion chamber valves. Adjusting the timing to the current load lowers fuel consumption and emissions.
  • a common type is the wellgelzellenversteller.
  • Vane adjusters include a stator, a rotor and a drive wheel. The rotor is usually non-rotatably connected to the camshaft. The stator and the drive wheel are also interconnected with the rotor coaxial with the stator and within the stator. Rotor and stator characterize oil chambers, which can be acted upon by oil pressure and allow a relative movement between the stator and rotor. Furthermore, the vane cell adjusters have various sealing lids. The composite of stator, drive wheel and sealing cover is formed by a plurality of screw connections.
  • the object of the invention is to provide a camshaft adjuster, which is particularly simple in construction and has a reliable connection to the camshaft.
  • the camshaft adjuster comprises a drive wheel, a stator and a rotor, wherein the rotor relative to the stator has a rotational degree of freedom and the rotor is fixed axially relative to the stator, wherein the camshaft adjuster arranged coaxially to the axis of rotation of the drive wheel an adapter sleeve and a connecting sleeve, wherein the adapter sleeve and the connecting sleeve are connected to one another on the one hand and on the other hand form an axial fixation of rotor, stator and drive wheel.
  • the rotor, the adapter sleeve and the connecting sleeve form a rotationally fixed unit, which is connectable to a camshaft end. This can be omitted a variety of screws, rivets, pins.
  • the adapter sleeve is formed connectable with a camshaft end.
  • the camshaft end is designed such that the adapter sleeve is centered over a collar or paragraph. This centering minimizes coaxiality errors.
  • the end-side, camshaft-facing end of the adapter sleeve forms an advantageously planar contact surface with the camshaft in order to absorb high forces.
  • the centering and the contact surface can be achieved by e.g. Knurled be such a surface that the reliability of the connection is increased.
  • the adapter sleeve is designed to carry oil.
  • the pipe of oil through the adapter sleeve forms oil paths short and it is low oil losses achieved by a small number of sealing points coupled components.
  • Other sleeves used in the camshaft adjuster may also be formed oil leading.
  • the sleeves used can be provided with sealing elements.
  • the adapter sleeve and the connection sleeve have one or more axial stops. These stops form a position fixing, wherein the rotor is braced and the drive wheel and the stator are provided with little axial play.
  • the advantage here is the integral design of these attacks as changes in diameter on the outer circumferential surfaces of the adapter sleeve and the connecting sleeve.
  • the adapter sleeve has a bearing for the drive wheel.
  • the adapter sleeve with the bearing is formed directly connectable to the camshaft end. Since a camshaft bearing is usually arranged at the end of the camshaft, forces are advantageously absorbed on the cylinder head.
  • the adapter sleeve is connected to the connecting sleeve by a thread.
  • the advantage here is the disassembly option. Internal and external threads as well as left and right-hand threads can be used. Furthermore, a thread-forming design on one of the two sleeves is conceivable.
  • connection sleeve with the adapter sleeve by an oversize connection, or press fit, braced. This ensures that when mounting the camshaft adjuster with the camshaft end, the central screw further strengthens and secures the interference fit.
  • the press fit can be made more efficient by knurling the surfaces of the sleeves.
  • the stator is positively connected to the drive wheel and centered on this.
  • the form fit transfers the torque from the drive wheel to the stator.
  • a seal can be provided, which forms an oil-tight space in the stator.
  • the axial cohesion between the stator and the drive wheel is formed via axial stops and through the connection between the adapter sleeve and the connecting sleeve.
  • pins, rivets or other standard parts can be used to form the torque transmission between the stator and the drive wheel.
  • Advantageous in the use of standard parts are low production costs.
  • the drive wheel, the stator and the rotor are particularly well centered to each other and achieved a very accurate positioning each other.
  • the outer diameters are formed differently in diameter.
  • the drive wheel, stator and rotor are centered on a common outer diameter, which is simple and inexpensive to produce.
  • functions such as centering and axial fixation can be realized via additional sleeves.
  • one of the sleeves has a centering for a stator, another sleeve a centering for a rotor, etc. Any combination of the functions and the number of sleeves is conceivable.
  • the adapter sleeve, the connecting sleeve and possibly further sleeves can be interconnected with additional means.
  • additional means can screws, washers, rings, pins, or similar. be.
  • the sleeves have a passage opening for the penetrating arrangement of a central screw, the camshaft adjuster attached to the camshaft end.
  • a sealing cover or a cover can be arranged on the unit, which seals the unit oil-tight against the environment.
  • adjusting unit such as sealing covers, bearings, locking units or oil guide plates, can be fixed by the adapter sleeve and the connecting sleeve as well as by additional sleeves.
  • Locking means may be circlips, circlips, nuts, screws or, advantageously, the sleeve itself. In this case, material is crimped by the sleeve, bent or otherwise reshaped.
  • An embodiment of the sleeve in sheet metal is advantageous.
  • the adapter sleeve on the camshaft-side end face concentric to the central axis circumferential recess.
  • This recess is in communication with oil supply holes of the camshaft.
  • the adapter sleeve axially parallel bores extending cut this recess. The bore exits open at the other end of the adapter sleeve in a first oil chamber.
  • the adapter sleeve has a concentric passage opening. This passage opening is penetrated by a central screw. A gap remains between the central screw and the diameter of the passage opening. This gap represents another oil supply.
  • the adapter sleeve has radial oil holes that connect the outer diameter with the inner diameter of the through hole.
  • the radial oil holes are angularly offset from the axial oil holes, so that no overlap of the holes and thus no short circuit in the oil circuit is formed.
  • the radial oil holes can also open into a circumferential groove, from which the oil is then forwarded to the corresponding oil chamber.
  • the oil passages may be arranged in an oil-carrying sleeve angularly oriented to an oil supply source.
  • the sleeves In order to realize an angle-oriented oil supply between the sleeves, the sleeves have anti-rotation elements. Thus, a reliable arrangement of the oil passages can be formed.
  • a sleeve may have a thread for attachment to a camshaft. This advantageously can be dispensed with attachment to a central screw and the sleeves are formed without through hole for a central screw.
  • the thread may be formed as an internal or external thread and advantageously justified in the direction of rotation of the drive wheel have a left or right-hand thread.
  • the sleeves used to reduce the weight inside hollow, perforated, slotted or formed as a cage may be filled, e.g. made of metal foam.
  • a hub is formed on the stator, which is located at one end of the stator.
  • This hub can advantageously be determined by the sheet thickness of the stator.
  • the hub supports the stator on a sleeve, preferably the connecting sleeve.
  • a spring element is arranged between the stator and the rotor.
  • the spring element braces the stator with the rotor in an advantageous direction with each other.
  • the winding body of the spring is advantageously mounted or guided on an outer diameter of one of the sleeves used, for example the adapter sleeve.
  • the spring may also be guided on the hub of the rotor or the stator or other components.
  • the sleeves used, or at least one of them formed as a sheet metal part.
  • This lowers manufacturing costs.

  • the camshaft adjuster is fastened by a central screw at the camshaft end.
  • the central bolt penetrates the sleeves used, which hold the camshaft adjuster together.
  • the screw head contacted in the composite one of the sleeves, preferably the connection sleeve. It is advantageous that the camshaft adjuster can be pre-assembled by the use of sleeves and then attached to the camshaft with only a central screw.
  • the central screw has a concentric passage opening which extends from the screw head to the threaded end.
  • This passage opening serves to guide the oil.
  • the oil guide is designed as a vent or oil return of the exiting the stator in the cover oil in the cylinder head.
  • the oil tightness is ensured by means of a cover.
  • the cover is advantageously finally mounted after installation of the adjuster.
  • the cover may have a sealing ring.
