Definitions
- the present invention relates to a valve arrangement for a valve-controlled internal combustion engine.
- a valve arrangement in which the rear and movement of the valve member not by a camshaft is effected and controlled. Rather, the invention Arrangement of an electrically operated valve drive used.
- JP-A-3-92518 is a drive device for a Valve arrangement in internal combustion engines, in which the Stator is made up of two approximately semi-cylindrical shells, the both in the circumferential and longitudinal directions of each The shell has split teeth facing the rotor.
- the individual teeth of each shell are each of a winding surrounded, whose central longitudinal axis runs in the radial direction.
- a matching design of the stand, the stator coils and the rotor of a drive device for a valve assembly in internal combustion engines is in the US 5,129,369. Again are radial and tangential The teeth of the stand divided in the direction of surrounded a winding, the central longitudinal axis in radial Direction runs.
- EP 0 485 231 A1 also shows a similar type of design of the stator, the stator coils and the rotor one Drive device for a valve arrangement in internal combustion engines.
- the stator, the stator coils and the rotor one Drive device for a valve arrangement in internal combustion engines are in the radial and tangential directions divided teeth of the stand each by a radially oriented Surrounded winding.
- the invention teaches a valve arrangement for a valve-controlled internal combustion engine, with an electric linear motor as an actuator for a valve member, which is defined by the features of claim 1.
- This arrangement enables a very small pole pitch of the Linear motor, so that a very high force density can be realized is.
- the force generated by the linear motor can be adjusted exactly along the stroke of the valve member. So it is not necessary to use the valve member with considerable to apply kinetic energy so this takes its final position. This means considerably less Energy required to actuate the valve member is than in the arrangements known from the prior art. This also means a significantly lower noise level and less wear.
- the stator winding By arranging the stator winding, it is possible to keep vibrations acting on the winding low, so that vibrations of the winding or friction of the winding on the Sheets are low. It is possible with minimal insulation material or lining material of the winding chamber get along. This also contributes to compactness and reliability of the overall arrangement. It also causes a high one Power density even with small linear motors because of the fill factor the winding chamber (winding volume in the winding chamber based on the total volume of the winding chamber) is high.
- the sheets preferably have at least one recess, which contains iron material for connecting the sheets.
- This Iron material can be formed by (packed) iron wires that penetrate the sheets across their surface. alternative the iron material can also be caused by iron particles be formed by means of synthetic resin or the like. in the recesses the sheets are pressed.
- the invention enables the construction of an actuator in which the at least one winding over its entire extent contributes to the effective generation of force in the linear motor.
- the winding has no end windings, such as this is the case with conventional engines.
- the reason for this is that the winding is completely between the sheets of the Stator is included in the winding chambers and the winding neither in the axial direction nor in the radial direction protrudes beyond the teeth of the stand.
- the valve arrangement according to the invention thus has an actuator, compared to a conventional engine, significantly less Copper to generate a comparable magnetic field having.
- the rotor can be an asynchronous rotor or Synchronous rotor, or specifically designed as a reluctance rotor his.
- Valve arrangement is the rotor with a sensor for path detection, preferably coupled to a moving coil arrangement.
- Actuator also a partial stroke of the valve arrangement is possible. This partial stroke can be detected via the sensor.
- Runner can be coupled to a resonance spring arrangement.
- the rotor is preferred as a hybrid rotor with an iron body are used in the copper or aluminum tires, designed.
- the invention relates to an internal combustion engine with at least one combustion cylinder, with at least a valve assembly for intake or exhaust valves with one or more of the above features.
- valve arrangement for a valve controlled Internal combustion engine schematically illustrated in longitudinal section.
- An electric linear motor 10 is used in the invention Valve arrangement as an actuator for a valve member 12.
- the Linear motor 10 has one with the valve member 12 via a Rod 14 coupled rotor 16 and a stand 18th
- the stand 18 is constructed from circular iron sheets 20, whose surface is perpendicular to the direction of movement B of the Runner 16 is oriented.
- the stand 18 faces the rotor 16 facing teeth 22, each having a closed, the Runner 16 have facing surface.
- the individual teeth 22 a circular cylindrical surface.
- oval sheets or sheets with a polygonal shape for Structure of the stand 18 to use.
- the stator 18 has stator windings 24 that are parallel are oriented to the surface of the sheets 20. To do this, some have the sheets 20 have a smaller diameter than those Sheets that form the teeth 22. So that are each between two adjacent teeth 22 open to the outside Winding chambers 26 are formed, in each of which one 18 concentric winding to the central longitudinal axis of the stator 24 is located.
- each of the sheets 20 has a recess 30 in the polymorphic iron material or packed iron wires for magnetic connection of the sheets is included.
- each winding 24 over its entire extent in the Winding chamber is arranged, it also carries over its entire Length for effective force generation in the linear motor at.
- the rotor 16 is a hollow cylindrical one Eisenring, the one on the stand 18 facing Has inner recesses axially spaced from each other, in which copper or aluminum rings 34 are added are.
- the rotor 16 thus works as a hybrid rotor.
- the rotor is on the end face facing away from the valve member 12 16 with a sensor 36 for path detection of the rotor 16 in the direction of movement B coupled.
- the rotor 16 is against the housing 40 with a resonance spring arrangement 42 supported.
