Definitions

  • the present invention relates to a segmented motor having the features of the preamble of claim 1.
  • Linear actuators which are similar to those described in DE 19825728, are known. These consist of two electromagnets. Between the electromagnets is the magnetic anchor, which moves between the pole faces of the two electromagnets. The armature is in connection with the valve of an internal combustion engine and is accelerated by two springs. nigt. Lever actuators, also based on the resonant oscillating principle according to DE 19712063 and DE 19854020 are known. The actuators operate on the same physical operating principle with the difference that the valve is not actuated directly, but via a lever and the lever between the pole faces of two magnets emotional.
  • valve lift can not be adjusted as desired.
  • Actuators are adjusted only small pitch and a large stroke.
  • dynamics of the actuators described above are determined by the springs and can not be varied. These possibilities of the actuators is not sufficient for the implementation of novel combustion methods. These require full variability of the valve lift and very accurate timing accuracy.
  • EP 1144813 a rotary motor, which is suitable in principle for the actuation of gas exchange valves, is shown.
  • the motor structure as well as the motor acting principle is not closer.
  • a reluctance principle or a synchronous motor concept is used.
  • the rotor design it is assumed that permanent magnets are embedded in the rotor and the magnetic feedback occurs via the rotor. This corresponds to the classic structure of synchronous machines. With this operating principle, the precise and stepless control of valves is possible.
  • the drive has a high mass of inertia. Therefore, the required dynamics for the operation of gas exchange valves can not be achieved. Therefore, it makes sense to use springs to assist the acceleration. This is embodied in FIGS. 6a to 7 of the patent EP 1144813. In order not to hold too high To achieve currents in the end positions, a holding means is provided in EP 1144813, which may also be a spring.
  • Such a segment motor further includes, as is apparent from FIG. 3 of DE 102005040389.1, a rotor design in which the rotor carrier is designed as a thin-walled pot, on the outside of which permanent magnet elements are arranged.
  • the rotor structure has basically proven to be robust.
  • the power transmission takes place via a transmission member that is connected to a shaft.
  • a recess on the bell is required.
  • the recess for the lever for valve coupling is expensive and reduces the rigidity of the rotor.
  • the requirements regarding temperature environment, vibration and shock load for the valve train are very high.
  • the impact load when the valve is set unmanently is very high.
  • the rotor impinges on a maximum stop.
  • the requirements for the highly dynamic function require in particular Diesel engine high forces.
  • the length of the actuator is limited by the cylinder and the valve distance.
  • the valve plane or axis is not symmetrical to the actuator, which means an eccentric mounting of the valve coupling to the rotor. This space available for the actuator must therefore be fully utilized in order to achieve a high power and torque yield.
  • the object of the invention is to provide a compact design of a segment drive.
  • the segment drive Due to the advantageous structure of the inventive segment drive this can be made compact and lightweight. In addition, it is highly dynamic, mechanically highly loadable and cost-effective to manufacture. He also has a low electrical power consumption.
  • the segment drive is advantageous very small.
  • the invention provides for two, three, four or more drives to be arranged in a modular housing to form a segment drive for a plurality of valves.
  • the advantageous provision of one or more housing intermediate parts, which carry parts of the inner stators of adjacent drives and in particular also receive or support the common bearing shaft for the adjacently arranged rotors, makes it easy to assemble by advantageously a few parts. Also, let the segment drive advantageously produce cost-effective with a reduction of the parts.
  • the housing of the segment drive is limited by Gehauseplatten that can accommodate part of an inner stator. Also, the outer Gehauseplatten serve to support the rotor of the adjacent drive.
  • the invention further provides for arranging several segment drives side by side as so-called benches on a cylinder block of an internal combustion engine.
  • the segment drive according to the invention fulfills the following requirements:
  • Construction is suitable for both a gasoline engine and a diesel engine
  • the rotor of the segment drive according to the invention has a low inertial mass, at the same time minimizing the losses of the magnetic circuit.
  • the magnetic circuit can be optimized primarily by minimizing the leakage losses. This is achieved by shortening the length of the iron loop and optimally enclosing the coils with soft iron. Furthermore, it is important to ensure that the permanent magnet elements are always in the magnetic circuit during the lifting movement.
  • the structure of a segment motor described in Fig. 1 of PCT / EP2005 / 000567 has the disadvantage that the outer coils and permanent magnets are not so effective.
  • the excitation yoke should be designed approximately as a three-quarter circle, whereby the magnetic field is homogeneous and the loss of power during a rotational movement is lower.
  • the rotor can then be made in the form of a pot and made more homogeneous, i. be embroidered with magnets over a larger segment. This reduces the structural load and thus enables mass reduction of the rotor.
  • the doubling of the number of poles allows approximately a force doubling compared to the embodiment in Fig. Ia of PCT / EP2005 / 000567.
  • the actuator can be made shorter with the same force demand. This in turn has an advantageous effect on the structural load of the rotor. As a result, the air gap between the rotor and the stator can be reduced, which advantageously leads to a power increase.
  • the energy efficiency can be more than doubled compared to the structure shown in Fig. 1 of PCT / EP2005 / 000567 by the measures described.

  • the actuators can be advantageously arranged in series, for example, on the inside of the valves. This allows a narrow and compact design on the cylinder head.
  • the one-sided coupling of the valves is very easy to install. Even in diesel engines, where the valves are usually vertical, the arrangement is very advantageous. In this case, the actuators are arranged on the outside of the valves. The spark plug is located between the valves.
  • the housing structure with rotor mounting and fixation of the outer and inner stator is crucial for the robustness of the structure and the cost of the mechanics.
  • the design must ensure that a lot of space is provided for the magnetic circuit, but at the same time the high forces acting on the bearing and the stator must be truncated to ensure long-term stability. Also, the manufacturing and installation tolerances are taken into account to allow the smallest possible air gaps on the rotor. For this purpose, various possibilities of housing construction and storage are shown.
  • the Gehauseomee provide that the actuators modular as a bank or alternatively as a twin or four-valve unit can be constructed. For cost reasons, it makes sense to combine all the actuators of the intake and exhaust valve side into a bank. It is also possible, in particular with a small valve angle, to combine two inlet actuators and two exhaust valve actuators in one housing. For reasons of ease of maintenance, however, it may also be expedient that only two or four adjacent actuators are combined into one unit. Adjacent ac- In this case, each tuatoren share an intermediate housing part or a common bearing part, in which a rotor or several rotors of adjacent actuators are partially stored. The housing of the segment drive is completed by a wider end wall.

This allows the contacts to be reduced and the cost of construction and electrical connection ⁇ rule to reduce the number. In addition, the rotation angle sensor allows better control, since a possible me ⁇ chanic clearance between the rotor and valve does not adversely affect the control.
  • each tooth of the yoke each carry an exciter coil.
  • the exciter coils are advantageously made of baked enamel wire in a step winding, so that the winding space is optimally filled. Also conceivable is a winding with hexacoils, which allow a good fullfactor.

  • the swivel allows the valve to turn around its axis, the bending shaft absorbs the axial misalignment.
