Description

The invention relates to a front part for a motor vehicle.

Motor vehicles have nose portions which form the nose of the vehicle and which are provided as a fairing, for example, of the bumper with a bumper cover. Also, air inflow openings are usually provided in the front part, through which air flows / is supplied for cooling of units, heat exchangers or brakes. Thus, the front part is also part of the aerodynamic concept of the vehicle, so that depend on the design of the bow part both the flow and the flow around the vehicle. Such Bugteile are for example by the US 8 210 600 B1 or the WO 2014/044490 A1 known.

The lower edge of the front section defines with the wheel contact point the angle of repose of the vehicle, which defines the maximum steepness of a ramp that can drive the vehicle without causing damage.

In more off-road motor vehicles, such as the so-called SUVs, the nose piece is pulled upwards rather, so that the slope angle is rather large, thereby less air flows through the nose piece or by the vehicle. In more sporty designed vehicles, the nose piece is pulled further downwards, so that the air flow around and through the vehicle is more affected, so that the related output is increased.

Since the nose piece is fixedly mounted on the motor vehicle, the vehicle manufacturer always has to find a compromise between the respective possible designs of the nose piece to select the nose piece with regard to the intended use of the motor vehicle. However, this always represents only a compromise, which always represents a deficit in the specific driving situation compared to the special solution.

Therefore, it is the object of the present invention to provide a nose piece for a motor vehicle, which is better adapted to the respective needs compared to the prior art. It is also the task of creating a motor vehicle with an improved, adapted nose piece.

The object is achieved with the features of claim 1.

An embodiment of the invention relates to a front part for a motor vehicle with an upper nose section element, which comprises substantially the entire upper front of the motor vehicle with introduced air flow openings, with a lower nose section element, which is disposed below the upper nose section element, and the lower edge of the bow portion, wherein the lower bow section element is designed to be interchangeable, and the lower bow section element is present in at least two variants, so that the lower bow section element mounted below the upper bow section element can be selected from the existing variants. As a result, depending on the desired needs with regard to the use of the vehicle, an adapted lower bow part element can be installed. If no off-road use is desired, the front part can be adapted to the desired road use. Thus, a lower bow part element can be installed, which only allows a smaller angle of repose. This causes in the present adjustment, however, no change in the balance of the vehicle, because the alternative lower front bumper elements can cause a respective comparable output.

It is particularly advantageous if, in a first variant, the lower bow part element is present as the first lower bow part element which allows a larger angle of slope and, in a second variant, is present as a second lower bow part element which allows a smaller angle of slope. So can be distinguished between rather off-road use and more street use.

It when the first lower bow part element has a front lower edge, which is arranged higher in the mounted state than the front lower edge of the second lower bow part element is particularly advantageous. This results in the first lower bow part element a larger allowable slope angle compared to the second lower bow part element.

It is also advantageous if the first lower bow part element has a front lower edge, which is arranged in the assembled state further back than the front lower edge of the second lower bow part element. This also increases the allowable slope angle at the first lower bow section element. Also, the flow or the flow around is varied, so that the second lower bow part element would cause an increased downforce without additional flow openings.

It is also advantageous if the first lower bow section element has no throughflow opening for the flow of air and the second lower bow section element has at least one throughflow opening for the flow of air. Thus, in the second lower bow part element, the flow is increased, so that thereby a shape-related increase in output can be compensated again.

It is also advantageous if the first lower bow section element has at least one throughflow opening for the flow of air and the second lower bow section element has at least one throughflow opening for the flow of air, wherein the flow cross section of the at least one flow opening of the first lower bow section element is smaller than the flow cross section the at least one throughflow opening of the second lower bow part element. Thus, in the second lower part of the bow element, the flow is increased, so that as well as a shape-related increase in output can be compensated again.

It is also advantageous if the second lower bow part element has a recess at its front upper edge, which forms a throughflow opening with the front lower edge of the upper bow part element. Even so, the flow between the lower and the upper part of the bow member is increased in the second lower bow part element, so that thereby a shape-related increase in output can be compensated again.

Furthermore, it is expedient if the second lower bow part element forms a flow channel starting from at least one throughflow opening, the outflow having a substantially ground-parallel outflow direction. Even so, in the second lower bow section element the flow is influenced downstream, so that thereby a shape-related increase in output can be compensated again.

The object is achieved with the features of claim 9.

An embodiment of the invention relates to a motor vehicle with a bow part according to the invention.

In the following the invention will be explained in detail by means of an embodiment with reference to the drawing. In the drawing shows:

1 a schematic view of a front part of a motor vehicle,

2 2 a side view of a bug of a motor vehicle with a front part with a first lower front part,

3 a side view of a bug of a motor vehicle with a nose piece with a second lower Bugteilelement,

4 a side view of a front part of a motor vehicle with a first lower Bugteilelement,

5 a side view of a front part of a motor vehicle with a second lower bow part element, and

6 a schematic sectional view of a bug of a motor vehicle with a nose piece.

The 1 shows nose piece 1 for a motor vehicle with an upper nose piece element 2 , Which essentially the entire upper front of the motor vehicle with introduced air flow openings 3 . 4 includes. It can also be seen that a radiator grille 5 and lights 6 in the upper nose section element 2 are arranged integrated. Under the lower edge 7 of the upper nose piece element 2 is a lower bow part element 8th arranged, which in particular the lower end of the bow part 1 forms. In the lower nose section element 8th is still a spoiler-like bulge 9 and a flow opening 10 intended for air.

The lower bow section element 8th is thus below the upper bow part element 2 arranged and executes the bow of the motor vehicle in the lower portion.

Here is the upper part of the bow 2 firmly connected to the vehicle and in particular not or only for repair etc. interchangeable. By contrast, the lower bow part element 8th designed to be interchangeable so that it can be replaced quickly by loosening provided connecting means. The interchangeability of the lower nose section element 8th is therefore provided because by the replacement of the lower nose section element 8th An adaptation of the vehicle can be made in particular to the wishes of the driver. For this lies the lower bow part element 8th in at least two variants before, so that under the upper Bugteilelement 2 mountable or mounted lower bow part element 8th from the existing variants is selectable.

The 2 and 3 respectively. 4 and 5 show different views of a bug of a motor vehicle 20 or a nose piece 30 . 40 with upper bow part element 31 . 41 and with lower bow part element 32 . 42 ,

In 2 is a bug part 30 shown, which with its lower edge 33 allows a slope angle α1, as the angle, which through the ground 34 and the line 35 between the wheel contact point 36 and the bottom edge 33 is formed. In 3 is a bug part 40 shown, which with its lower edge 43 allows a slope angle α2, as the angle, which through the ground 44 and the line 45 between the wheel contact point 46 and the bottom edge 43 is formed. The slope angle α1 is greater than the slope angle α2. This means that with a motor vehicle 20 with a bug with one lower nose piece element 32 larger embankments are passable than with a lower bow part element 42 , The lower bow section element 32 therefore allows in a first variant as the first lower Bugteilelement 32 a larger slope angle α1 than the lower bow section element 42 in a second variant, which allows only a smaller slope angle α2.

The 4 and 5 show the nose parts 30 respectively. 40 in an enlarged view. Each identifies the identical upper noseboard element 31 . 41 which is the same in both representations. below the upper bow part element 31 . 41 In each case, a lower bow part element is shown mounted, which exists in two variants. The first lower bow section element 32 is a lower bow part element, which allows a larger slope angle α1 and the front lower edge 37 is pulled up stronger while the second lower bow part element 42 a lower bow part element is, which allows a smaller slope angle α2 and the front lower edge 47 is pulled up less strongly. The first lower bow section element 32 thus has a front lower edge 37 on, which is higher in the assembled state than the front lower edge 47 the second lower bow part element 42 ,

Also in the 4 and 5 to realize that the first lower bow part element 32 a front lower edge 37 has, which is arranged in the assembled state further back than the front lower edge 47 the second lower bow part element 42 , The leading edge of the front lower edge 47 is thus more forward than the front lower edge 37 the first lower bow part element 32 ,

The first lower bow section element 32 is therefore more suitable for motor vehicles that are driven away from normal roads, it thus represents an off-road variant, while the second lower bow section element 42 is more suitable for motor vehicles that are not driven away from normal roads, so it represents an on-road variant.

In the 4 and 5 it can also be seen that the first lower bow part element 32 has no flow opening for the flow of air. In contrast, the second lower nose section element 42 at least one flow opening 48 for the flow of air on. This is the second lower bow part element 42 at its front upper edge 49 with a return 50 formed, which with the front lower edge 51 of the upper bow part element a flow opening 48 forms.

Alternatively, also the first lower bow part element 32 Have at least one flow opening for the flow of air, wherein the second lower bow part element 42 has at least one flow opening for the flow of air, wherein the flow cross-section of the at least one flow opening of the first lower bow part element 32 smaller than the flow cross-section of the at least one flow opening of the second lower bow part element 42 ,

The 6 shows a bug 60 a motor vehicle with a nose piece 61 with an upper nose piece element 62 and a lower nose piece element 63 , In the bow 60 is still a bumper 66 and a radiator assembly 67 and a hood 68 arranged. The lower bow section element 63 is under the upper bow section element 62 attached and has a flow opening 64 and a flow channel 65 on, through which air can flow according to the arrow shown. The outflow of air in this case essentially has a ground-parallel outflow direction.
