Description

DEVICE FOR THE OPERATION OF A VEHICLE WING FIELD OF INVENTION The invention relates to the operation of a vehicle flap, in particular a rear spoiler or spoiler, between a stationary operating position and an established working position, with a control member acting in conjunction with a curve path on the base position of a vehicle. linear relative movement parallel to a first pivot axis of the vehicle spoiler, with the actuation of the vehicle spoiler.

Such a device for driving a vehicle spoiler is known from German patent application DE-AS 26 58 433. In this device is the spoiler mounted rotatably on a transverse edge on a hinge and on this edge is shaped towards in exceeding the curve path. The control member acting together as the curve path is firmly connected with a drive cable which serves for linear adjustment of the control member that runs on the control surface of the control curve, and results in an elevation or lowered from the vehicle spoiler, this relatively simple opening and closing movement of the spoiler is appropriate for the purpose of vehicle application in the movable roof area. However, it is not appropriate for a wing that must perform a complex movement approximately one vehicle spoiler in the conformation of a rear or aft spoiler.

DETAILED DESCRIPTION OF THE INVENTION It is an object of the present invention to manufacture a drive device for a vehicle spoiler that allows to perform a complex tilting movement of the spoiler with simple means. This object is achieved by the features set forth in claim 1. Further advantageous embodiments of the invention are characterized in the following claims. In this way, the invention is created, in other words a drive device with a spoiler with two axes displaced in the transverse direction, for a vehicle spoiler which, in addition to a trajectory along a path of different bends, is also adjustable. in space, so that it adjusts to a relatively complex tilting position compared to the state of the art and meets the special requirements of the practice. This adjustment of the vehicle's spoiler in the tilting is carried out because, contrary to the current state of the art, no fixed connection has been provided between the curve and spoiler path of the vehicle, but a connection through a lever where it has been provided an additional lever or an auxiliary lever that is independent of the control curve and that to a certain extent causes a greater precision of the pivoting adjustment of the aileron caused by the first lever. By means of such a construction it is ensured that the drive device for the vehicle spoiler will need relatively little space and the vehicle spoiler will operate and can be adjusted to an optimum position for the current which is what is especially sought when used as a spoiler and spoiler and especially as a stern spoiler. The adjustment of the relative rotation between the control curve, which is perfectly constructed as an arrow of cross-members and the first lever of rotation to it coordinated, can be carried out in the way that is desired, properly for a first lever of rotation mounted stationary and a colisa of adjustable crossbar, and on the other hand, by a fixed stationary slider and linearly adjustable second and second levers. It is preferred, because of the embodiment of the variants, a linearly adjustable curve and curve path.

In the following, the invention will be described in detail by means of an example shown in the drawings, in which: FIG. 1 shows a schematic side view of an embodiment of the device according to the invention for operating the flap of a vehicle that serve as spoiler or stern spoiler; Figure 2, a perspective view of Fig. 1, without representation of the vehicle spoiler. In Fig. 1, the sloping end of the outer roof covering of a vehicle with the reference figure 1, a tank marked with the reference figure 2, is indicated in that place it is closed by the front end of the vehicle. vehicle hinge 3, when it is in the resting position. In the rest position the vehicle flap 3 is indicated by 3A, while in its working position, that is, in a fully exposed position, it is indicated by 3D. Two intermediate positions of the flap or aileron are indicated with 3B and 3C, in the tank 2, there is arranged a profiled frame 4, in the form of a trough, consisting of several individual sheets that serves as a mounting frame for a fixing of the strips of fixing 24, of the device for the actuator of the spoiler 3, of the vehicle.

The structure of this drive device is explained in particular below in reference to Fig.

As can be seen from Fig. 1, it makes the vehicle spoiler 3, a relatively complex movement compared to the current state of the art, the flap not only scales around a single axis next to a transverse edge, but makes a movement combined tilt and displacement, which is characterized in that its leading edge in the direction of travel, moves along a curved path that rises from the resting position rises relatively strongly, then reaches a maximum and falls below the point starting, as shown in Fig. 1, in the different stages of movement schematically by means of an x. The back edge 6, performs the opposite as shown by a dotted straight line, essentially a steep ascent movement, and leaves behind a section essentially greater than the front edge 5. This movement is caused by the control device according to the invention, which is based on two turning levers of which one runs with one end on a curved path, while the other lever indirectly through the flap 3 of the vehicle controls a simple auxiliary tilting movement. As shown in FIG. 2, the actuating device for the vehicle spoiler 3, according to the invention, presents a curve path in the form of a crosspiece slide 7, which is linearly adjustable on a rail. hollow profile guide 8, which runs transversely to the longitudinal axis of the vehicle. The slide 7, and the guide rail 8, are shown in a cross section in Fig. 1. The cross piece 7 is provided at the lower end with a guide rod 9, which runs transversely and grips in a space hollow 10, constructed in addition to this of the guide rail 8. This hollow space 10, further presents a cut 10a, which in cross section has a circular shape, in which a driving agent is introduced to move the colisa 7, for example, a discharge cable, not shown, which will pass through a guide tube 11, at one end of the guide rail 8. The cross-piece of the cross-piece 7 is constructed in a circular manner in its protruding part on the guide rail 8, and ends in a rod 12, which fixes the curved path to the sill and runs along a spatial curve, which allows the tilting adjustment of a control member forcibly driven in a pivotable manner. In the present case, it is treated in the control member, working in conjunction with the control curve or with the slide 7, of a first pivoting lever 13, which is mounted on one side of the guide rail 8, and is pivotable by means of a first pivot lever axis 15 in a pivotable assembly 14. The first pivot lever axis 15, runs parallel to the guide rail 8. Approximately half the height presented the first pivot lever 13, a cut 16, in the form of a claw, which is constructed complementary to the rod 12, of the cross piece 7, holding the cross piece 12 from above, and riding on it. In Fig. 2, it is shown in two positions, the turning lever 13, properly in its operating position in which the pivoting lever 13, rides on the ends of the crossbar stud 7, and in a rest position in which the pivoting lever 13 rests on the lower ends of the cross member 7. In the working or operating position, the turning lever 13 is indicated, with the reference figure 13, and in the position at rest with the reference figure 13 '. The same applies to the cross bar that in its extreme left position shown in Fig. 2, which corresponds to the working position of the first turning lever 13, is indicated with the reference figure 7, while in the another extreme position corresponding to the rest position of the turning lever 13 ', it is marked with 7 '. At the upper end of the first turning lever 13, another support or pivot bearing is provided which in FIG. 2, is schematically indicated with the digit 17. This support also pointing as the first upper bearing 127, fixes a first axis of tilting 18, for the vehicle spoiler 3. This pivoting axis 18, is schematically indicated in Fig. 2, in general, consisting of the upper bearing 17, of a corresponding bore in the upper end of the first turning lever 13, and of a corresponding pin that is provided on the inner side of the spoiler 3, and fixedly attached thereto. As can also be seen in FIG. 2, there is the first pivot lever axis 15, below the guide path of the cross member 7, while the upper pivot lever axis coincides with the first Tilting axle 18, of the vehicle spoiler 3, in all positions of the first turning lever 13, comes to rest above the crossbar stud 7. Opposite the first turning lever 13, there is a second turning lever , which at the lower end is rotatably mounted by means of a second axis 20, of pivoting lever on a pivotable support 21, which on its other lateral edge has fixedly the guide rail 8, and precisely slightly above the bearing or support of tilt 14, for the lower end of the first pivot lever 13. The second pivot lever axis 20, runs parallel to the first pivot lever axis or to the first pivot axis 18, the second pivot lever 19, has fork shape and c On this, another coaxial tilt bearing, which is not shown in Fig. 2, for fixing the second pivot lever axis 20.

At the upper end of the second turning lever 19, there is an upper rotary support 22, for the pivoting connection with a corresponding pivoting support member on the inner side of the vehicle spoiler 3. This pivoting support member is located viewing in the longitudinal direction of the vehicle, distanced from the tilt support for the upper end of the first turning lever 13. The upper pivoting bearing or support 22, fixed to the second tilting axis 23, for the vehicle spoiler 3. The second pivoting lever 19, is not opposite to the first pivot lever 13, in grip with the crossbar stud 7, and performs its pivoting movement indirectly by means of the vehicle spoiler 3, using its tilt adjustment by means of of the first turning lever 13, as best seen in Fig. 1. This forced driving of the upper end of the second turning lever 19, is indicated in Fig. 1, with the sequence 23A, 23B, 23C and 23D. The upper end of the second turning lever 19 leaves behind in the adjustment of the vehicle spoiler 3, between its rest position and its working or operating position, essentially a circular path. The upper end of the first pivot lever 13 also runs in the same direction a circular path with turns as shown by the succession of the figures 18A, 18B, 18C and 18D. These two curved trajectories have such a shape that the previously explained movement of the front edge 5, and of the rear edge 6, of the vehicle spoiler 3, can be realized. The actuating device explained above can be provided, either as a single part in the center of the vehicle spoiler, or also as two such parts on both sides of the vehicle spoiler. The arrangement is suitable for the most different vehicle hinges, such as Coc pitchable roofs motor wheel discs, engine chests, wind flaps and other similar parts
