Description

[0001] The invention relates to a flow guidance arrangement for a motor vehicle, comprising a wing device arranged in the rear region of the motor vehicle and a spoiler device arranged below the wing device.

[0002] EP 0 199 010 B1 discloses a flow-guiding arrangement comprising a wing device arranged in the rear area of ​​the motor vehicle and a spoiler device arranged below the wing device. The combination of the wing device and the spoiler device enables the flow-guiding arrangement to effectively generate downforce on the rear axle. However, the flow-guiding arrangement does not allow adaptation of the generated downforce to different driving situations. DE 10 2016 111 429 A1 and DE 10 2014 110 390 A1 each disclose flow-guiding arrangements for the rear area of ​​a motor vehicle, wherein both the wing device and the spoiler device are designed to be adjustable by electric motors.

[0003] Against this background, the object of the invention is to create a simply constructed flow guidance arrangement with a wing device by means of which a downforce is effectively generated on the rear axle, wherein the downforce can be adapted to different driving situations.

[0004] This object is achieved according to the invention by a flow guiding arrangement having the features of claim 1.

[0005] The flow guidance arrangement according to the invention comprises a vane device arranged in the rear region of the motor vehicle. The vane device is mounted on a vehicle body in such a way that airflow around the vane device is possible on both the top and bottom sides.

[0006] The flow-guiding arrangement further includes a spoiler device mounted on the vehicle body in the rear area of ​​the motor vehicle, below the wing device. Air flow only passes over the spoiler device at its upper side.

[0007] The combination of wing device and spoiler device in the rear area of ​​the vehicle can effectively generate downforce on the rear axle of the vehicle.

[0008] According to the invention, the wing device is designed to be movable by a motor between a first setting position and a second setting position and / or the spoiler device is designed to be movable by a motor between a rest position and a working position. In this case, the wing device in the first setting position and / or the spoiler device in the rest position is arranged in such a way that a low downforce is generated. The wing device and / or the spoiler device is / are arranged in the second setting position or the working position in such a way that a high downforce is generated. The wing device and / or the spoiler device can be moved by a motor, preferably continuously and electrically, between the first setting position and the second setting position or between the rest position and the working position in order to vary the downforce generated by the flow guidance arrangement on the rear axle.This enables adaptation of the generated downforce and thus the aerodynamic properties of the vehicle to different driving situations.

[0009] Preferably, the wing device and the spoiler device are designed to be motor-driven, whereby the generated downforce can be controlled particularly precisely and over a wide range.

[0010] According to a preferred embodiment, the wing device and / or the spoiler device has a pivoting element that can be pivoted relative to a vehicle body. By pivoting the pivoting element, the downforce generated by the flow-guiding arrangement can be easily changed.

[0011] The vehicle body preferably has a spoiler recess into which the spoiler device is at least partially, preferably completely, immersed in its rest position. This makes the spoiler device not immediately visible from the outside in its rest position, which can improve the overall visual appearance of the motor vehicle. Depending on requirements, the spoiler device can be extended, preferably continuously, from the spoiler recess to vary the generated downforce. In the working position, the spoiler device can be extended to a greater or lesser extent.

[0012] According to a preferred embodiment, the wing device and / or the spoiler device consists at least partially of plastic, whereby the wing device and / or the spoiler device is lightweight and can be produced cost-effectively.

[0013] Preferably, the spoiler device is arranged in the rear area above a bumper. Advantageously, the spoiler device is arranged in the rear area below a tailgate. This allows for particularly effective downforce generation on the rear axle.

[0014] According to a preferred embodiment, the wing device is arranged on a tailgate, so that the wing device folds away with the tailgate when it is opened. This allows unhindered access to a body space located beneath the tailgate when the tailgate is open.

[0015] An embodiment of the invention is explained in more detail below with reference to the accompanying figures. They show: Fig. 1 a highly simplified side view of a motor vehicle rear area with a flow guide arrangement according to the invention, wherein a movable wing device is in a first setting position and a movable spoiler device is in a rest position, and Fig. 2 the highly simplified side view of the rear area of ​​the vehicle with the flow guide arrangement from Fig. 1, wherein the movable wing device is in a second setting position and the movable spoiler device is in a working position.

[0016] In the Fig. 1 shows a flow guide assembly 10 according to the invention, which is arranged in a rear region 12 of a motor vehicle 14. The flow guide assembly 10 comprises a wing device 16 and a spoiler device 18. In the present embodiment, the wing device 16 is made at least partially of plastic.

[0017] The wing device 16 comprises a movable wing pivot element 17 and a stationary wing holding device 22, wherein the wing pivot element 17 is pivotally mounted on a cantilevered distal holding device end 20. The wing holding device 22 is fastened by the proximal holding device end 24 to a tailgate 26 of the motor vehicle 14. The wing device 16, specifically the wing pivot element 17 of the wing device 16, is motor-driven via a motor M1, which in the present embodiment is an electric motor.

[0018] Below the tailgate 26 and above a bumper 28, a spoiler recess 30 is formed in a vehicle body 29 of the motor vehicle 14. A spoiler pivot element 19, which in the present embodiment forms the spoiler device 18, is pivotably mounted in said spoiler recess. The spoiler device 18 is motor-driven via a motor M2, which in the present embodiment is an electric motor and is arranged in the spoiler recess 30. Devices not shown in detail for supporting the spoiler device 18 in the rest position can be provided in the spoiler recess 30.

[0019] In the Fig. 1, the wing device 16 is arranged substantially parallel to a vehicle floor 32. The spoiler device 18 is in the position shown in Fig. 1, the spoiler is completely immersed in the spoiler recess 30. Consequently, the flow guide arrangement 10 generates only a small downforce on a vehicle rear axle 34.

[0020] In Fig. 2, the wing pivot element 17 of the wing device 16 is pivoted on the holding device 22 into the second setting position, so that a rear pivot element end 36 of the wing pivot element 17 pointing away from the holding device 22 points away from the vehicle floor 32. Furthermore, the spoiler device 18 is pivoted out of the spoiler recess 30 with a rear spoiler device end 38 pointing away from the tailgate 26. The wing device 16 and the spoiler device 18 are positioned such that the flow guide arrangement 10 generates a high downforce on the vehicle's rear axle 32.

[0021] The wing device 16 and the spoiler device 18 are continuously adjustable via the motors M1, M2 between the Fig. 1 shown first setting position or rest position and the one in Fig. 2 in order to vary the downforce generated by the flow guide arrangement 10 on the vehicle's rear axle 34. Preferably, the wing device 16 and the spoiler device 18 can be moved independently of one another. Alternatively, the movement of the wing device 16 and the movement of the spoiler device 18 can be coupled.
