Definitions

the invention relates to a wellgelzellennockenwellenversteller according to the preamble of claim 1.
the object of the invention is to provide a wellgelzellennockenwellenversteller whose restoring moments are set very precisely.
a vane-type camshaft phaser is used.
This creategelzellennockenwellenversteller builds axially very short, which benefits the tight space conditions of both transversely and longitudinally installed drive trains.
a spiral spring with a rectangular profile holds the rotor with respect to the stator in a certain angular position.
the rotor in a necessary for the engine start early exhaust camshaft position are brought.
the alternating torques of the camshaft can be compensated, which are different degrees of effectiveness in the two directions of torque of the camshaft.
the coil spring can be twisted in a particularly advantageous manner in the rest position in the torque direction "early”, since the adjustment of the copezellennockenwellenverstellers in the torque direction "late” due to the supporting effect of the alternating moments anyway faster.
the spiral spring it is achieved by means of the spiral spring, that the adjustment in "early” as fast as in "late".
a spiral spring with a rectangular profile can be manufactured with very low tolerances.
the rectangular wire of the coil spring can be particularly well grasped by a jig and then angled. Then, the angled bent portion makes it possible to further hold the coil spring at this angled corner portion with a jig and to wind the spring to an exact dimension.
a round wire would be difficult to grip here with a clamping device, since such a round wire is only frictionally engaged and not form-fit to grip. The winding takes place substantially around the central axis of the spiral spring.
the coil spring is not wound exactly evenly, since some of the turns of the coil springs should abut each other, so that there is generated during the tension of the coil spring, a friction torque that prevents a swinging of the coil spring. This damping effect thus acting friction can also be adjusted exactly as a result of the rectangular profile.
the bent or angled region can be in a particularly advantageous manner the radially outer end of the spiral spring relative to the central axis.
the angle can be selected in a particularly advantageous development so that the coil spring rests already in the unloaded state of the Nockwellenverstellers on the side plane.
This damping and operationally secure measure according to claim 4 is of particular advantage when the coil spring is open - i. without protective cover - rests on the camshaft adjuster. This angle of less than 90 °, due to its rigidity during operation, bends only so slightly that an anti-rotation lock against the stator is still ensured.
the radially inner end can be fixed against rotation relative to the rotor.
the inner end can be inserted, for example through the side plane in a receiving recess of the rotor.
a rotatably connected to the rotor component is the so-called spring adapter.
Claim 9 shows a particularly advantageous embodiment of the invention. Consequently, the rectangular profile of the spiral spring has two opposite edge lengths, deviate from the other two edge lengths, the shorter edge lengths facing the side or facing away from this. Simplified, this means that the rectangular profile of the spiral spring "upright" stands on the page level.
the coil spring is bent in a particularly advantageous manner at the angled portion in the stiffer direction.
this angled area on the one hand during operation of the viagelzellennockenwellenverstellers also heavier auzubiegen so that the spring can not slip out of the attachment to the stator.
the coil spring is softer in the direction of rotation about the central axis, which improves their function. It is also possible with this orientation of the profile to accommodate more turns with more friction in the same space.
the wellgelzellennockenwellenwellenversteller With a wellgelzellennockenwellenwellenversteller the angular position between the crankshaft and the camshaft is changed during operation of an internal combustion engine. By turning the camshaft, the opening and closing times of the gas exchange valves are shifted so that the internal combustion engine brings its optimal performance at the respective speed. Of the wellgelzellennockenwellenversteller allows infinite adjustment of the camshaft relative to the crankshaft.
the wellgelzellennockenwellenwellenversteller has a cylindrical stator 1, the rotation with a in Fig. 2 apparent gear 2 is connected.
the gear 2 is a sprocket over which a chain, not shown, is guided.
the gear 2 may also be a toothed belt wheel over which a drive belt is guided as a drive element.
the stator 1 is drivingly connected to the crankshaft in a known manner.
the stator 1 and the gear 2 may alternatively be integrally formed with each other when the other side of the stator 1 is openable.
the stator 1 and the gear 2 may also be made of metallic material or of hard plastic.
metallic materials u. a. Sintered metals, steel sheets and aluminum in question.
the stator 1 comprises a cylindrical stator base body 3, on the inside of which protrude webs 4 at equal intervals radially inwardly. Between adjacent webs 4 pressure chambers 5 are formed, in which, controlled by a non-illustrated 4/3-way valve, pressure medium is introduced. Between adjacent webs 4 protrude wings 6, which protrude radially outward from a cylindrical rotor body 7 of a rotor 8. These wings 6 divide the pressure chambers 5 between the webs 4 in each case in two pressure chambers 9 and 10th
the webs 4 lie with their end faces sealingly against the outer circumferential surface of the rotor base body 7.
the wings 6 in turn lie with their end faces sealingly against the cylindrical inner wall of the stator main body 3.
the rotor 8 is rotatably connected to the camshaft, not shown. In order to change the angular position between the camshaft and the crankshaft, the rotor 8 is rotated relative to the stator 1. For this purpose, depending on the desired direction of rotation, the pressure medium in the pressure chambers 9 or 10 is pressurized, while the respective other pressure chambers 10 or 9 are relieved to the tank.
the stator 1 is in one piece as an in Fig. 2 apparent pot-shaped stator cover running, which is firmly bolted to the gear 2.
the stator cover is designed as a casting with a cast edge 20.
the end faces of the webs 4 and the wings 6 are on the one hand close to the gear 2 and on the other hand close to the stator cover.
This stator cover and the gear 2 also limit the pressure chambers 5 between the wings 4 in the axial direction.
a lock between the rotor 8 and the stator 1, for example, by a spring-loaded locking pin 21 This is accommodated in one of the wings 6.
this locking bolt 21 is moved by the spring force of a helical compression spring, not shown, into a locking position in which it engages in a locking opening of the stator 1.
the locking bolt 21 is loaded by the pressure medium against the spring force and pushed back, so that the rotor 8 is unlocked from the stator 1 and the viagelzellennockenwellenversteller can get into its control position.
the coil spring 12 rests on a side plane 22 arranged perpendicular to the central axis of the vane-cell camshaft adjuster on the stator cover.
the coil spring 12 is rotatably connected to the rotor 8 with a radially inner end 14.
the radially outer end 15 of the coil spring 12 is rotatably and positively supported on the stator 1.
the radially outer end 15 of the coil spring 12 in the unloaded state of the rempligelzellennockenwellenverstellers angled at an angle ⁇ of 88 °. This angled end 15 is inserted into a receiving recess 16 of the stator 1.
the radially inner end 14 of the coil spring 12 is bent radially inwardly and engages in a radially aligned receiving recess 24 of a rotatably connected to the rotor 8 spring adapter 23 a.
This spring adapter 23 has an unspecified pin, which by means of a press fit into a Hub of the rotor 8 is inserted.
the spring adapter 23 is rotationally fixed relative to the rotor 8.
the radially inwardly bent end 14 and the radial receiving recess 24 in this case point to the central axis 25 of the copegelzellennockenwellenverstellers.
the coil spring 12 has a rectangular profile which rests "edgewise" on the side plane 22. That is, two opposite edge lengths 26a, 26b of the rectangular profile deviate from the other two edge lengths 27a, 27b.
the one short edge length 26a faces the side plane 22, whereas the other short edge length 26b faces away from the side plane 22.
the one long edge length 27a points radially inwards, whereas the other long edge length 27b faces radially outward.
the vane camshaft adjuster may be applied to an intake camshaft and / or an exhaust camshaft.
the vane cam phaser may apply to a single camshaft find that both the inlet gas exchange valves and the outlet gas exchange valves adjusted.
the inner end of the coil spring is connected to a component which is rotationally fixed to the rotor.
This component can thus be the rotor itself.
it may be a pin or a sleeve which is positively connected to the rotor or via a press fit with or without corrugation.
a pin or such a sleeve is also referred to as a spring adapter, since at least one of their functions is the connection between the rotor and the coil spring.
the rectangular profile of the coil spring can also be square.
an additional spring cover which protects the coil spring on the one hand against dirt and other Umwalteinflüssen and on the other hand can form a friction partner and a "captive" for the coil spring.
this guard can also be made for example of plastic.
the diegelzellennockenwellenwellensteller protected anyway by a chain case or belt box, so u. U. no additional protective cover necessary.
the camshaft adjuster is not driven by a toothed belt or a chain but by a gear of an axially offset second camshaft adjuster.
