Definitions

  • the invention relates to an actuator with an electromotive drive, from which, via a gear transmission, in particular a reduction gear, a toothed segment rotatably arranged on a shaft can be pivoted from a first position limited by a first stop to a second position limited by a second stop is drivable.
  • Such actuators can be used in many ways. For example, they can be used for devices in which a swivel drive is electromotive in one swivel direction, while in the other direction a return spring moves the shaft back to its starting position.
  • a swivel drive is electromotive in one swivel direction
  • a return spring moves the shaft back to its starting position.
  • the shaft is the throttle valve shaft which carries the throttle valve and can be moved by an electric motor from a closed position to an open position, while the return movement to the closed position is carried out by a return spring.
  • actuators which recognize the striking of the stops via an implemented intelligence and store these end positions, so that when the end positions are reached further no striking takes place. However, this learning process is carried out each time the actuator is started up again.
  • the object of the invention is therefore to provide an actuator of the type mentioned which, with a simple construction and avoidance of damage due to overloading and avoidance of operational disturbances, enables a minimized design of the transmission and drive.
  • toothed segment can be pivoted relative to the shaft by a limited pivoting angle against a spring force in one and / or in the other pivoting direction of the toothed segment.
  • the toothed segment and shaft are connected to one another in a defined position assignment without play.
  • the toothed segment is a toothed ring section which is arranged so as to be displaceable in its radially circumferential circumferential direction on a hub part rigidly connected to the shaft, the toothed ring section being acted upon by the spring force in one and / or in the other pivoting direction is.
  • toothed ring section can be acted upon by the spring arms of a clamp spring with opposite bias in a rest position, in which each spring arm both acts on the toothed ring section and is in contact with a stop of the hub part, a reduction in the required components is achieved.
  • the play-free, defined position assignment of the toothed segment and the shaft to one another takes place.
  • the displaceability of the toothed ring section from the rest position in one and / or in the other pivoting direction is preferably limited by pivoting stops.
  • a simple embodiment of the clip spring consists in that the clip spring is a V-shaped leaf spring which is arranged pivotably on the hub part in the connecting region of its legs forming the spring arms. To determine an increasing spring characteristic, the legs can be started from Hub part have a reducing width towards their free legs.
  • the clip spring preferably consists of a CuBe alloy.
  • the leaf spring can be pivotally supported on the inside of the connecting region of its legs on the hub part and have a continuous recess through which a radial arm of the hub part projects , wherein the leaf spring is supported with the outside of its connecting region on a support connected to the radial arm.
  • a particularly small number of components are required for holding and guiding the clamp spring if the continuous recess is a slot extending in the direction of the longitudinal extension of the leaf spring, through which the radial arm projects through approximately the same cross-section, and if the support is a bolt extending axially to the longitudinal axis.
  • the hub part can have a hub that can be arranged fixedly on the shaft, from which a sector-like guide region extends radially with a peripheral, arc-like guide path on which the toothed ring section is slidably guided with a guide encompassing the guideway.
  • the hub part is a flat sheet metal stamped part, this can be produced particularly easily and inexpensively. If the swivel angle of the toothed ring section relative to the shaft is limited by swivel stops which are firmly connected to the toothed ring section and which can be abutted against counter stops formed on the hub part in their path of movement, a construction with few components is achieved.
  • the hub part can have an arcuate recess in its area radially between its hub and its guideway, into which stop arms of the toothed ring section projecting the pivot stops protrude and against which the ends of the arcuate recess which form in the circumferential direction and form the counter stops can be abutted.
  • the toothed ring section can be easily mounted by plugging onto the guide track and snapping the stop arms into the arcuate recess.
  • toothed ring section is a plastic part, then only minimal friction losses occur when it is displaced on the guideway.
  • a component can also be produced simply and cheaply as an injection molded part.
  • the shaft is preferably a throttle valve shaft of a throttle valve connector for an internal combustion engine, a throttle valve being attached to the throttle valve shaft and being pivotably arranged in a throughflow opening of the throttle valve connector between a closed position and an open position. If the throttle valve shaft can be pivoted against the force of a return spring from the closed position into the open position, the force of the return spring can no longer lead to a hard stop of the toothed segment on a rigid stop defining the closed position.
  • the return spring can act on the radial arm of the hub part in the closing direction of the throttle valve shaft.

  • a throttle valve is fixedly arranged in the flow opening on the throttle valve shaft 11. By pivoting the throttle valve shaft 11 between the closed position and the open position, the throttle valve also pivots between its closed position blocking the throughflow opening and its open position at least largely opening the throughflow opening.
