  • EP 2 233 343 A2 shows a flap arrangement which is provided for varying the inflow of cooling air into the engine compartment of a vehicle. The actuation of the flaps takes place there via a side of the flaps arranged lever mechanism. In this blind the lever mechanism used to adjust the flaps is open
  • Flaps of the air flow which flows through the blind exposed. In a vehicle, this air flows in through the grille and may contain dust, dirt and sand. In this blind there is therefore the danger that the Ver adjusting mechanism thereby heavily contaminated.
  • forces for opening and closing the flaps only act on a narrow side of each flap.
  • the flaps of the blind are to be long and / or comparatively thin and thus lightweight, such introduction of force can cause problems. In particular, it may happen that the actuated flap is twisted around its longitudinal direction and possibly no longer closes properly in an end region facing away from the adjustment mechanism.
  • the present invention seeks to provide an improved air damper assembly.
  • an air damper assembly which is particularly suitable for regulating the flow of air to a radiator of a motor vehicle having a first flow passage having a first flap pivotable about a first pivot axis between an open position and a closed position rotatable shaft, which has a first eccentric, with a first coupling element which is coupled to the first eccentric and connected via a first joint to the first flap, wherein the first eccentric, the first coupling element and a between the first joint and the first pivot axis extending portion of the first flap a rotational movement of the shaft as a four-bar linkage for pivoting the first flap are movable such that a first angle, which includes the first coupling element with the first eccentric increases in the pivoting of the first flap from the open to the closed position.
  • the idea underlying the invention is to actuate the first flap by means of a four-bar joint, which is formed by the first eccentric, the first coupling element and a portion of the first flap, which extends between the first joint and the first pivot axis.

  • this makes it possible to arrange the first joint, the first eccentric and the first coupling element for actuating the flap at any one or more arbitrary locations across the width of the flap, viewed in the longitudinal direction thereof. A twisting or twisting of the flap about the longitudinal direction and consequent leakage problems can be avoided in this way.
  • the first angle increases when closing the first flap, at a constant rotational speed of the shaft at the beginning of the closing process
  • a relatively large pivoting speed of the first flap at relatively low operating forces and at the end of the closing operation when the first flow channel is already almost completely closed by the first flap, to achieve a relatively low pivoting speed of the first flap at relatively high operating forces.
  • This is particularly advantageous because with continued closing of the first flap on this by the damming of the airstream before the first flap acting resistance forces for further pivoting in the fully closed position increasing actuating forces required.
  • the air flap arrangement according to the invention is thus adapted to the loads actually acting on the first flap during operation.

In the open position of the second flap this releases the second flow channel, while the second flap substantially closes the second flow channel in its closed position.
  • the shaft has a second eccentric in this embodiment. It is provided a second coupling element, which is coupled to the second eccentric and connected via a second joint with the second flap. In this case, the second eccentric, the second coupling element and a section of the second flap extending between the second joint and the second pivot axis can be moved as a four-bar linkage for pivoting the second flap by a rotary movement of the shaft.
  • a second angle, which the second coupling element encloses with the second eccentric, increases during the pivoting of the second flap from the open position to the closed position.
  • a bending of the shaft can be avoided or at least reduced.
  • first and the second pivot axis extend parallel to each other.
  • the first pivot axis and the second pivot axis can also be arranged in parallel and spaced from each other.
  • a parallel arrangement of the pivot axes can facilitate a windproof coupling of the flaps moving in opposite directions to one another on the windward side.
  • the first flap and the second flap form a closed wing profile, in particular a convex symmetrical wing profile, when the first flap and the second flap are each in the open position.
  • first and the second flap in the opened state form a closed, preferably aerodynamically favorable, profile.
  • first and second flap in the opened state form a closed, preferably aerodynamically favorable, profile.
  • Swivel axis advantageously arranged in the region of a leading edge of the sash profile.
  • the front edge of the wing profile is rounded and thus provides sufficient space for the pivotable mounting of the first and second flap.
  • a rounded front edge is aerodynamically favorable.
  • downstream edge regions of the first and second flaps lie on one another such that the airfoil profile has a closed rear edge when the first and second flaps are each in the open position.
  • the air masses flowing in the first flow channel and the second flow channel can be brought together again at a closed trailing edge while avoiding large flow separations.

  • the first and the second eccentric, the first and the second coupling element and at least a portion of the shaft are received in an interior of the airfoil when the first and the second flap are each in the open position.
  • the eccentric, the coupling elements and the shaft are well shielded from the incoming air, and entrained by the air entrained dusts, sand and the like can less easily attach to the eccentrics and the coupling elements and pollute them.
  • An impairment of the mobility of the coupling elements, the eccentric and the shaft against each other and against the flaps by such contamination is avoided.

Abstract

L'invention concerne un agencement de volets d'aération destiné, en particulier, à réguler l'afflux d'air vers un radiateur d'un véhicule automobile. L'agencement de volets d'aération comprend un premier canal d'écoulement, un premier volet, un arbre muni d'un premier excentrique et un premier élément de couplage. Le premier volet peut pivoter entre une position ouverte et une position fermée autour d'un premier axe de pivotement. En position ouverte, le premier volet ouvre le premier canal d'écoulement, tandis qu'en position fermée ledit volet ferme sensiblement le premier canal d'écoulement. L'arbre est rotatif autour d'un axe de rotation. Le premier élément de couplage est couplé avec le premier excentrique et relié au premier volet par le biais d'une première articulation. Le premier excentrique, le premier élément de couplage et une partie du premier volet, qui s'étend entre la première articulation et le premier axe de pivotement, peuvent être déplacés par un mouvement de rotation de l'arbre sous forme de quadrilatère articulé pour faire pivoter le premier volet, de sorte qu'un premier angle, formé par le premier élément de couplage avec le premier excentrique, s'accroît lorsque le premier volet pivote de la position ouverte à la position fermée.
