Definitions

  • the invention relates to an electromagnetic relay, in particular a motor vehicle relay, with a magnetic yoke and with a relay coil and with respect to at least a first fixed contact held moving contact, which is kept closed in currentless relay coil of a piezoelectric actuator as a result of its control.
  • a relay is from the WO 2005/001868 A1 known.
  • a relay as it is often used in particular in a motor vehicle as an electromagnetic switch is activated via a control circuit in which the relay coil is located, and usually switches at least one other circuit, in the example, an electric motor, a gasoline pump or often safety-related vehicle components , For example, a fuel injection system, is connected.
  • a monostable relay requires a permanent current flow through the relay coil (excitation winding) both to attract and hold the armature to assume and maintain the working position (ON). If the current flow is interrupted, the relay goes autonomously into its rest position (OFF).
  • a bistable relay may have two different stable states in the de-energized state, for which it switches over to a current pulse generated in the control circuit in the other switching state and this maintains until the next control pulse. The bistable relay must therefore be activated actively in order to reach a defined switching position.
  • the relay control is designed to control the exciter current in the relay energization by means of a switch such that first a pull-in current flows through the excitation winding and after the expiration of a holding current, which is smaller than the attraction current.
  • the invention has for its object to provide a preferably suitable as a motor vehicle relay electromagnetic relay that works as low as possible, especially in hold mode (ON).
  • the relay has a moving or changeover contact with currentless relay coil closed holding, hereinafter also referred to as a piezo actuator Piezostapelaktor with parallel to the axis of rotation of a hinged armature Krafthubides and thus forms a hybrid system with monostable behavior with only very low power consumption.
  • the moving or changeover contact is preferably kept closed in the currentless field winding by means of the piezoelectric actuator indirectly via the hinged armature against which the moving contact in the form of a spring contact, spring biased.
  • the relay according to the invention is thus comparable to a bistable system according to the principle of holding operation.
  • the relay coil or field winding is currentless in contrast to a conventional monostable relay.
  • the piezoelectric actuator only needs a short current flow when it is driven, while only a voltage has to be present thereafter at only a very small leakage current (holding operation). Since the piezoelectric actuator thus operates almost without power and the relay coil is de-energized, the relay according to the invention in the holding operation also operates practically without power.
  • the hybrid piezo relay system provided thereby is particularly suitable for safe switching.
  • the monostable behavior ensures that the piezo relay in case of power failure, especially in case of failure of the vehicle electrical system voltage of a motor vehicle, reliably autonomously passes into a defined state. Since the piezoelectric actuator only maintains the contact closure in the hold mode and in the case of a currentless relay coil, as long as its drive voltage is applied, a spontaneous contact opening takes place when the drive voltage drops as a result of the voltage drop of the supply or vehicle electrical system voltage.
  • the relay according to the invention is particularly advantageous in the automotive sector, since the low power loss associated with a corresponding CO 2 savings of the motor vehicle.
  • the temperature development the relay coil of the hybrid piezo relay system according to the invention ie the operating temperature compared to conventional relay considerably lower and approximately room temperature. This offers the considerable advantage of a particularly flexible or variable design of the installation space for the piezo relay.

  • a piezoelectric actuator piezoelectric Elongator
  • a piezoelectric actuator designed in particular as a piezoelectric bending transducer replaces the field winding or coil and acts directly on the normally open contact.
  • a piezoelectric actuator used, which acts in direct mechanical contact on the hinged armature.
  • the piezoelectric actuator is used, in addition to or as an alternative to a pole leg of a U-shaped magnetic yoke surrounding excitation winding for lifting the hinged armature of the pole face to support a flap armature acting on the mechanical return spring to overcome an undesirable adhesive force.
  • the piezoelectric actuator of the relay according to the invention is designed as a (piezo) stack actuator (stack) whose power stroke direction runs parallel to the axis of rotation of the hinged armature.
  • a lever transmission is suitably provided, which converts the power stroke into a clamping stroke for the releasable fixing of a tensioning element held on the movable contact.
  • the transmission ratio is suitably 2: 1, so that a force stroke of the piezoelectric actuator of, for example, ⁇ 15 ⁇ m leads to a clamping stroke ⁇ 30 ⁇ m.
  • the one-sided on the hinged armature or moving contact (changeover or changeover) held tension element is guided rudd lake in an advantageous embodiment in a nip and held there non-positively due to the activation of the piezoelectric actuator.
  • the nip is preferably provided on the magnetic yoke.
  • a slot is provided which extends radially relative to the relay coil and is interrupted or closed at a suitable location by a narrow web formed by the magnet yoke material.
  • the piezoactuator acting on the clamping lever is supported on a support leg whose distance from the clamping lever is adapted to the actuator height of the piezoactuator.
  • an axial functional leg extending at right angles to the radial pole leg is preferably provided with a U-shaped receiving pocket for the piezoactuator.
  • the mutually parallel U-legs go into the supporting leg or in the clamping leg of the pole leg over.
  • the hinged armature is articulated about the axis of rotation.
  • the relay coil on the one hand against the hinged armature and on the other hand on the magnetic yoke, that is attached to the opposite side of the hinged armature pole, for example, riveted.
  • this is formed by a bead-like clamping groove in which the tension element rests securely.
  • a clamping cam which engages in the clamping groove, is expediently provided on the clamping lever, while the clamping groove is then located on the opposite gap side on the remaining pole leg of the magnetic yoke.
  • the moving contact is preferably designed as a spring contact for generating a force acting on the hinged armature spring restoring force.
  • an approximately L-shaped spring element is suitably bent or shaped, wherein one of the bent spring legs are fixed to the functional leg of the magnetic yoke and the other spring legs on the hinged armature.
  • the piezoelectric actuator Since the piezoelectric actuator is known to behave similarly to a capacitor in the current consumption, on the one hand only at the moment of generation of the clamping force, a current flow is required. On the other hand, for safe release of the clamping in case of failure of the control voltage for driving the piezoelectric actuator that is connected in parallel with a suitable ohmic resistance. This ensures that the relay safely transitions to the predetermined state, in particular by a correspondingly reliable opening of the normally open contact or by a contact change in the case of a changeover contact.

  • the relay coil 7 can be controlled without current, without the hinged armature 4 drops and consequently the contact 5, 6a opens.
  • Fig. 2 shows in a side view of the pole leg 2a of the magnetic yoke 2 a clamping arm 12 formed on the pole leg 2a, which is formed by a longitudinal slot 13 extending in the radial direction y in the pole leg 2a.
