Embodiment Construction

[0019] figure 1 A representation of a vehicle floor 1 of a motor vehicle 2 is shown from below, wherein in figure 1 Above the figure, the opening 3 is closed by the shutter 4. exist figure 1 In the lower part of the figure, the flap is not shown, whereas the opening 3 in the vehicle floor 1 can clearly be seen. The opening 3 in the floor 1 or in the floor lining 6 serves as a play space for a rear axle control lever 5 of the rear axle or rear wheel suspension of the motor vehicle 2 .

[0020] figure 2 Shown is a perspective view of a vehicle floor 1 with a control lever 5 for the rear axle (however in figure 2 The opening 3 of the rear axle control lever is not shown in the figure and has a flap 4 for covering the opening 3, wherein two different positions of the flap 4 are schematically shown.

[0021] The vehicle floor 1 is equipped with a floor lining 6 in order to form it as flat and closed as possible, so that as few air flow turbulences as possible form below the ...

Abstract

The invention relates to a vehicle underbody (1) that has an underbody paneling (6) with at least one opening (3) for the at least temporary extension of a rear axle link (5) therethrough. The opening(3) is covered by a shiftable flap (4). The flap (4) can be shifted counter to a restoring force of the force accumulator (9) to at least temporarily open the opening (3).

Description

technical field [0001] The invention relates to a vehicle floor having an opening, in particular an opening for a rear axle control lever of a motor vehicle. Background technique [0002] Flow-friendly configurations are becoming more and more important in motor vehicles. For a favorable drag coefficient (cw value), it is therefore advantageous if the vehicle floor is covered as completely as possible, so that a favorable air flow can be created through the underside of the vehicle. However, two opposite openings are provided in the region of the rear axle control lever, through which the rear axle control lever can be deflected, for example in the case of a corresponding movement of the chassis or in the suspension ejected state of the motor vehicle on the lifting frame. superior. These openings are therefore necessary for the movement of the chassis, but they represent an aerodynamically unfavorable area of ​​the floor since they lead to increased air turbulence. Conte...
