There is a need for a front part of a motor vehicle which, for a low coefficient of air resistance, allows a sufficiently large or high cooling air flow. The object of the invention is to provide such a front part of a motor vehicle.
    [0003] This object is formed by a front part of a motor vehicle, comprising a plurality of cooling air apertures arranged next to each other and separated from each other by ribs, comprising several flaps or valves arranged next to one another others associated with the cooling air openings, which can be moved between a first position in which they suppress a flow of cooling air through the cooling air openings and a second position in which they release a cooling air flow. cooling air flow through the cooling air apertures, characterized in that reinforcing edges 3031938 - 2 - extend in the region of the ribs at one side thereof facing towards the interior, and in that the flaps are rotatably supported at the reinforcement edges so that corresponding landing points The flaps are located at the reinforcing edges outside the cooling air apertures and therefore outside the cooling air flow when the flaps are moved to the second position. The front part according to the invention therefore has a plurality of cooling air apertures arranged next to one another and separated from one another by ribs, and several flaps arranged next to one another and associated with the air openings. which can be moved between a first position in which they suppress a flow of cooling air through the cooling air apertures, and a second position in which they release a cooling air flow through them. cooling air apertures, reinforcing edges extending in the region of the ribs at one side thereof facing inwards, and the flaps being rotatably supported at the reinforcing edges of the ribs; such that corresponding bearing points of the flaps are located at the reinforcing edges outside the openings cooling air and therefore outside the cooling air flow when the flaps are moved to the second position. The front part according to the invention makes it possible to ensure a low coefficient of resistance of the air as well as the provision of a sufficiently large cooling air flow. According to an advantageous development of the invention, several flaps can be moved in common between the first position and the second position around a common axis of rotation, which extends through bearing points flaps and substantially parallel to the lower end of the flaps, so that in the first position, a front end of each flap is pivoted upwards and in the second position, the front end of each flap is pivoted downwards. This feature of the invention is particularly advantageous. For opening the cooling air openings, the flaps are pivoted about the common axis of rotation so that the front ends of the flaps are pivoted from top to bottom so that the front ends of the flaps, seen in driving direction, are located at the front. In this way, particularly effective guiding of the airflow through the cooling air apertures can be ensured. Preferably, a lip is formed at the front end of each flap, which, in the first position, stiffens the respective flap 5 and, in the second position, serves to guide the cooling air flow through the flap. respective cooling air aperture. The lip at the front end of each flap, when the cooling air openings are open, serves as a cooling air collector and causes a particularly efficient flow of cooling air through the air openings. cooling. In the closed state of the cooling air openings, the lips stiffen the flaps to retain them in a defined manner in the closed state. Preferably, the flaps arranged next to each other are connected or connected to each other at the lower end by projections, the axis of rotation of said flaps preferably extending through these projections, and the flaps. being, preferably, directly clipped through these protrusions into recesses of the reinforcing edges. According to this feature of the invention, it is possible to do without a retaining frame for the shutters. As a result, a particularly simple form of construction of the front part is ensured. The invention is further characterized in that: - a common motor for the common movement of several flaps between the first position and the second position is associated with flaps that can be moved in common between the first position and the second position the motor being positioned at one side laterally beside the plurality of flaps arranged next to each other, - that on each side of a longitudinal central axis of the motor vehicle is each time positioned a group consisting of flaps 30 can be moved in common between the first position and the second position, which is each time associated with a common motor for moving the flaps together between the first position and the second position. Preferred improvements of the invention also result from the following description. Embodiments of the invention will be explained in more detail with the help of the drawings, but not limited thereto: FIG. 1 illustrates a partial front perspective view of a front portion of a motor vehicle according to the invention with open cooling air openings; Figure 2 illustrates a partial perspective rear view of the front portion according to the invention with open cooling air apertures; Figure 3 illustrates a partial perspective view of the back of the front portion according to the invention with closed cooling air openings; and Figure 4 illustrates a side view of the front portion according to the invention with closed cooling air apertures. The invention relates to a front part of a motor vehicle, in particular a front part for a high performance vehicle such as a sports car.
    [0004] In high performance vehicles, there is typically a conflict of objectives between a low coefficient of air resistance, also referred to as the cw value, and a necessary flow rate of the cooling air flow through openings. cooling air of the front part. The invention proposes a front part with which this conflict of objectives can be solved, that is with which on the one hand it is possible to obtain a low coefficient of resistance of the air and with which else A sufficiently large or large cooling air flow can be provided through the cooling air openings. Figures 1 to 4 illustrate different views of a front portion 10 according to the invention. The front portion 10 has a plurality of cooling air openings 11 which are positioned next to one another in at least one row. The respective row of the cooling air apertures 11 positioned next to each other extends in this case in the transverse direction of the motor vehicle. The cooling air apertures 11 positioned next to each other are separated from each other by ribs 12 of the front part 10. The front part 10 also has several flaps or valves 13 also positioned at each other. next to the others, associated with the cooling air openings 11 arranged next to each other. In the exemplary embodiment illustrated, a flap 13 is associated with each cooling air opening 11, the flaps 13 being movable by means of a motor 14 between a first position and a second position. flaps 13 in the first position, suppressing a flow of cooling air through the cooling air apertures 11, while the flaps 13 in the second position free cooling air flow at through the cooling air apertures 11. The cooling air apertures 11 or flaps 13 illustrated in FIGS. 1 and 3, with respect to a longitudinal central axis of the motor vehicle, are arranged on one side of that that is to say from the front, seen in the opposite direction of the driving direction, on the left side of the longitudinal median axis. On the opposite side of the longitudinal central axis, an identical number of cooling air apertures 11 with flaps 13 are preferably provided or provided. Several flaps 13, namely each time the shutters 13 positioned on one side of the longitudinal central axis, can be moved in common between the first position and the second position, namely around a common axis of rotation 15. The respective axis of rotation 15 of the flaps 13 extends in preferably, through a rear and bottom end 16 of the respective flaps 13. The respective flaps 13 may in this case be displaced around the respective axis of rotation 15 so that in the first position a front end 17 of the respective flaps 13 is pivoted upwards and that, in the second position, the front end 17 of the respective flaps 13 is pivoted downwards. In the region of the ribs 12 separating from each other the cooling air apertures 11 positioned next to each other, are formed, at one side thereof facing inwards, reinforcement edges 18. The flaps 13 are rotatably supported on the reinforcing edges 18 and such that corresponding bearing points of the flaps 13 are located at the reinforcing edges 18 outside the cooling air apertures 18. 11 and therefore outside the cooling air flow when the flaps 13 are moved to the second position. As a result, a particularly advantageous flow of cooling air through the cooling air openings is ensured when the flaps 13 are moved to the second position. Preferably, at the front end 17 of each flap 13 is produced in each case a lip 20. In the first position of the respective flap 13, the respective lip 20 serves to reinforce the respective flap 13 in order to maintain the flap 13. closed in a defined manner in the first position. Thus, when the respective flap 13 is transferred to the second position and releases the respective cooling air aperture 11, the respective lip 20 serves as a cooling air collector and consequently as an element for guiding the cooling air. cooling air flow to further improve the flow of cooling air through the respective cooling air aperture 11 when the flap 13 is transferred to the second position. As best seen in Fig. 2, the flaps 13 disposed adjacent to each other at the lower or rear end 16 are connected to each other by projections 21. Through these projections 21 extends the axis of rotation 15 of the flaps 13, the flaps 13 preferably being directly clipped through these projections 21 in corresponding recesses 19 of the reinforcing edges 18. In this way, the flaps 13 can be fixed simply to the part before 10 without additional retaining frame.
    [0005] The front portion 10 according to the invention for a motor vehicle therefore has a plurality of cooling air apertures 11 positioned next to each other, which are separated from each other by ribs 12. With each opening of Each cooling air 11 cooperates with a shutter 13 through which the cooling air flow through the respective cooling air opening 11 can be blocked or released. In the region of the ribs 12 which separate the cooling air apertures 11 from one another, extend, at each inwardly facing side thereof, reinforcing edges 18 which improve the rigidity ribs 12 with respect to bending and rotation or torsion during actuation or movement of the flaps 13 and at which the bearing points for the flaps 13 are made; The bearing points for the flaps 13 are therefore positioned outside the opening cross sections of the cooling air apertures 11, so that air can flow unobstructed through the openings of the cooling apertures 11. cooling air 11 when the flaps 13 are open. The guiding of the air or the flow of air through the cooling air openings 11, when the flaps 13 are open, is further improved by the lips 20 in the region of the front ends 17 of the flaps 13, these lips 20, in the closed state of the flaps 13, serving to reinforce them with respect to the forces of the air which are exerted. When the flaps 13 are open, the front ends 17 of the flaps 13 are lowered and are located forwardly in the driving direction, so that the lips 20 effectively collect the flow of cooling air and guide it in the direction of the cooling air apertures 11. As already explained, the shutters 13 are directly engaged in the reinforcing edges 18, namely in the corresponding recesses 19 thereof, by means of the projections 21, by which shutters 13 positioned next to each other are connected to each other, so that one can do without a retaining frame for the flaps 13. In parallel with the projections 21 through which flaps 13 positioned next to each other are connected to each other and are clipped into the recesses 19, are provided additional projections 22 at the rear end and lower 16 of the flaps 13, 20 which serve to connect the flaps 13 positioned next to each other at the rear and bottom end 16 thereof. The flaps 13 positioned on each side of a longitudinal median axis can preferably be moved in common between the first and second positions each time by a common control motor 14, the control motor 14 being positioned laterally beside the respective flaps 13. In this case, the respective control motor 14 can rest directly on the axis of rotation 15 and move the flaps 13. Alternatively, it can also be envisaged that the respective control motor 14 is not located on the rotation axis 15 but on the contrary, that it transfers, by means of levers and arms, the rotational movement to the flaps 13. In addition, a control motor in the form of a linear drive can also be used 13. Naturally, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of the invention.
