Description

The invention relates to a device for draining spray water in vehicles with a subfloor and at least one edge arranged on the vehicle wheel, at least in the direction of travel behind the wheel means for collecting the spray water are arranged, which derive the spray to the vehicle center.

Such devices are used in vehicle construction to catch spray water, which is whirled up by the wheels during driving from a wet roadway, and to drain at a suitable location. This should be avoided in particular a disruptive to the subsequent traffic spray formation and excessive pollution of the vehicle.

The generic FR 2 675 108 A1 discloses a device for discharging spray water according to the preamble of claim 1. A disadvantage of this device is that the means for collecting the spray water profiling the vehicle floor strong.

The DE 297 13 764 U1 shows an arranged in the direction of travel behind the wheel extension of the wheel housing shell on the bounced splash water splashes while driving and is discharged via the introduced grooves in the direction of the vehicle center. The disadvantage, however, is that the spray drips on the extension of the wheel housing shell so that it drips in front of a running in the direction behind it back wheel on the road and thus can lead to a deterioration of the liability of this wheel.

It is therefore an object of the present invention to provide a low-noise device for discharging spray water in a vehicle, by means of which a spray formation and the risk of a wheel floating on precipitation is reduced and whose air resistance is low.

This object is solved by the features of patent claim 1.

A vehicle with a device according to the invention is claimed in claim 10.

An apparatus for draining sprayed water in vehicles has a lower floor and at least one rim arranged on the vehicle wheel, at least in the direction of travel behind the wheel means for collecting the spray are arranged, which derive the spray to the center of the vehicle and means for discharging water spray are arranged on the subfloor, which receive the spray water from the means for catching and divert to a rear in the direction of travel of the vehicle.

By arranged on the underbody means for deriving, which receive the spray water from the means for catching and divert to a rear in the direction of travel of the vehicle, passes significantly less water spray in front of a wheel behind it, which does not deteriorate its adhesion properties in rain excessively. In addition, the spray water can drip off centrally in the rear part of the vehicle and thus leads to less disturbing spray formation behind the vehicle.

Here are the means for draining when not in use submerged. Thereby, a possible aerodynamic or acoustic impairment can be limited by the means for deriving the essentials.

In a preferred embodiment, the means for deriving at an outside temperature below a threshold in the subsoil are sunk. The threshold value is particularly preferably in a temperature range in which freezing spray water is to be expected. This can prevent the means of discharge by ice or snow being damaged or impaired in their function.

In a preferred embodiment, the means for discharging protrude from the subfloor in a rainfall detected by a rain sensor. Since the means for deriving only have to fulfill a function during precipitation, the operating time can be reduced by the measurement data of a vehicle-side rain sensor.

In a preferred embodiment, the means for catching are formed as part of a Radhausschale. In particular, the means for catching form an extension of the wheel housing shell in front of and / or behind the respective wheel, these extensions being chamfered towards the center of the vehicle.

In a preferred embodiment, the means for deriving are formed as strips. The strips are very easy to lower in the underbody. In addition, the strips may have gutters for better drainage of the spray water. Otherwise, the wind provides for a derivative of the drops of water on the last.

In a preferred embodiment, the means for deriving comprises a continuous central strip, which dissipates the spray of all tires at least one side of the vehicle. On the central rail, which is aligned substantially in the vehicle longitudinal direction, the water drops collected to water drops as quickly as possible from a front to the rear of the vehicle, where it can drip.

In a preferred embodiment, the means for discharging comprise at least one feed bar per wheel, which derives the spray water from the means for catching to the central bar. Depending on the need, several such feed bars can be arranged per wheel, so that as much spray water as possible reaches the central bar. At the rearmost wheels, the feed bar can also be omitted, since a discharge of the spray water to achieve the advantages of the invention is not absolutely necessary here.

In a preferred embodiment, the central strip ends at the rearmost in the direction of travel wheel.

Further details and advantages of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings.

Therein, the figure shows a schematic view of a subfloor of a vehicle.

According to the figure has a vehicle 1 an underbody 2 with four peripheral recesses in which wheels 3 be able to walk. Every bike 3 is partially edged by a wheel arch, with parts of the wheel arch as a means of catching 4 are formed, that of the wheel 3 can catch up swirled splashing water. Here are the means for catching 4 both in the direction of travel FR before, and behind the wheel 3 arranged. The means to catch 4 are beveled so that the wind blows away the spray water to the vehicle center FM out. Between the FR front and rear wheels 3 are sloping feeders 5b arranged that the spray water from the means for catching 4 record and a central bar 5a forward. Each vehicle side has a central bar 5a essentially in the vehicle longitudinal direction at the wheels 3 past. The central bar 5a ends with the rear wheel in direction FR 3 where the splashing water can drip off. The feed bars 5b and the central bars 5a can in the subsoil 2 be sunk so that no aerodynamic or acoustic impairments arise. This is preferably done at outside temperatures below 5 ° Celsius as protection against frost and / or in the absence of precipitation, determined by a rain sensor.
