Definitions

  • the present invention relates to a valve arrangement for a valve-controlled internal combustion engine.
  • the invention relates to a valve arrangement in which the reciprocating movement of the valve member is not effected and controlled by a camshaft. Rather, an electrically operated valve drive is used in the arrangement according to the invention.
  • DE 30 19 109 AI describes a valve arrangement which is based on a linear motor for actuating the valves.
  • the linear motor is controlled by a microprocessor depending on one or more motor parameters (speed, fuel quantity, etc.). However, no information on the design of the linear motor can be found in this document.
  • a gas valve control with a gas exchange valve which is actuated by an electromagnet arrangement.
  • a special configuration of the pole leg of the electromagnet arrangement generates a signal related to the movement of the armature in the control line of the electromagnet arrangement. This signal can be evaluated to identify any anchor position without additional sensors.
  • a major problem when using an electromagnet arrangement for actuating the valve is the high level of noise when the respective end positions are reached, the abrupt braking when the end positions are reached and the high holding currents required.
  • differential electromagnet arrangements which are also proposed in various ways and which are subjected to increasing currents in a targeted manner in order to achieve the required thrust of approximately 300-400 N for car internal combustion engines.
  • the valve which is loaded by a spring arrangement, therefore initially carries out an oscillating movement before an iron plate arranged on the valve stem bears against the armature of the electromagnet arrangement, so that a much lower holding current is required.
  • the maximum engine speed is considerably limited.
  • the start-up time is relatively long since it takes some time for the valve assembly to swing into its desired position due to the high dynamic force required.
  • EP 0 485 231 AI also shows a similar type of design of the stator, the stator coils and the rotor of a drive device for a valve arrangement in internal combustion engines.
  • teeth of the stator divided in the radial and tangential directions are each surrounded by a radially oriented 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 achieved.
  • the force generated by the linear motor can be precisely adjusted along the stroke of the valve member. It is therefore not necessary to apply considerable kinetic energy to the valve member so that it takes on its end position. This means that considerably less energy is required to actuate the valve member than in the arrangements known from the prior art. This also means significantly less noise and less wear.
  • the arrangement of the stator winding makes it possible to keep the vibrating forces acting on the winding low, so that vibrations of the winding or friction of the winding on the metal sheets are low. This makes it possible to make do with minimal insulation material or lining material of the winding chamber. This also contributes to the compactness and reliability of the overall arrangement. This also results in a high power density even with small linear motors, since the filling factor of the winding chamber (winding volume in the winding chamber in relation to 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.
  • the iron material can also be formed by iron particles which are pressed into the recesses in the metal sheets by means of synthetic resin or the like.
  • the invention enables the construction of an actuator in which the at least one winding contributes over its entire extent to the effective generation of force in the linear motor. This means that the winding has no end windings, as is the case with conventional motors. The reason for this is that the winding is completely accommodated between the sheets of the stator in the winding chambers and the winding does not protrude beyond the teeth of the stator in the axial direction or in the radial direction.
  • the valve arrangement according to the invention thus has an actuator which, compared to a conventional motor, has considerably less copper for generating a comparable magnetic field.
  • the rotor can be designed as an asynchronous rotor or as a synchronous rotor, or in particular as a reluctance rotor.
  • Valve arrangement the rotor is coupled to a sensor for path detection, preferably a moving coil arrangement.
  • the rotor can be coupled to a resonance spring arrangement.
  • the runner is preferably designed as a hybrid runner with an iron body in which copper or aluminum tires are inserted.
  • the invention relates to an internal combustion engine with at least one combustion cylinder, with at least one valve arrangement for intake or exhaust valves with one or more of the above features.
  • valve arrangement for a valve-controlled internal combustion engine is schematically illustrated in longitudinal section.
  • an electric linear motor 10 serves as an actuator for a valve member 12.
  • the linear motor 10 has a rotor 16 coupled to the valve member 12 via a rod 14 and a stator 18.
  • the stand 18 is constructed from circular iron sheets 20, the surface of which is oriented perpendicular to the direction of movement B of the rotor 16.
  • the stand 18 has teeth 22 facing the rotor 16, each of which has a closed lateral surface facing the rotor 16.
  • the individual teeth 22 have a circular cylindrical outer surface.
  • oval sheets or sheets with a polygonal shape for the construction of the stand 18.
  • the stator 18 has stator windings 24 which are oriented parallel to the surface of the sheets 20. For this purpose, some of the sheets 20 have a smaller diameter than those sheets which form the teeth 22. In this way, between two adjacent teeth 22, open winding chambers 26 are formed, in each of which there is a winding 24 which is concentric with the central longitudinal axis of the stator 18.
  • the type of connection of the individual windings gen 24 or its application of electrical current depends on the desired type of motor (single or multi-phase motor).
  • each of the sheets 20 has a recess 30 in which polymorphic iron material or packed iron wires for the magnetic connection of the sheets is contained.
  • each winding 24 is arranged over its entire extent in the winding chamber, it also contributes to the effective generation of force in the linear motor over its entire length.
  • the rotor 16 is a hollow cylindrical iron ring which, on its inner surface facing the stator 18, has recesses which are axially spaced apart and in which copper or aluminum rings 34 are received.
  • the rotor 16 thus works as a hybrid rotor.
  • the rotor 16 is coupled to a sensor 36 for detecting the path of the rotor 16 in the direction of movement B.
  • the rotor 16 is supported against the housing 40 with a resonance spring arrangement 42.
