Description

[0001] The present invention relates to a set for producing a wheel house arrangement for a wheel house of a motor vehicle, comprising a wheel house shell with a cooling channel, wherein the cooling channel is designed, in an installed state of a wheel house arrangement produced with the set in a motor vehicle, for guiding cooling air to a brake system of the motor vehicle, wherein the wheel house shell has an inlet opening for the cooling channel.

[0002] Furthermore, the present invention relates to a wheel house arrangement for a wheel house of a motor vehicle, a motor vehicle with a wheel house arrangement and a method for providing a wheel house arrangement on a motor vehicle.

[0003] Motor vehicles have so-called wheel arches to accommodate the wheels. Depending on the vehicle's engine power, the wheel arches can also serve to supply cooling air to the braking system, particularly the front-wheel braking system.

[0004] For example, cooling the brake system may be omitted in vehicles with comparatively low engine power. In high-powered vehicles, cooling is usually essential to achieve the necessary deceleration values.

[0005] Due to the different cooling requirements, the current state of the art provides for several wheel house variants depending on the engine power, even for otherwise identical vehicles. One wheel house variant is intended for vehicles with lower engine power and features no or only a small cooling duct. Due to the lack of a cooling duct or its small size, this variant also reduces the vehicle's drag coefficient. A second variant is provided for vehicles with higher or higher-powered engines. This variant is equipped with a sufficiently sized cooling duct, but also increases the vehicle's drag coefficient.

[0006] The design and manufacturing effort associated with the required variants is disadvantageous for cost reasons.

[0007] DE 10 2010 055 639 A1 discloses a motor vehicle with at least one cooling air duct formed in a floor plate thereof for supplying a wheel brake device of the motor vehicle with a cooling air flow, wherein the at least one cooling air duct is assigned an adjustable closure element in the form of a closure plate which, in turn, can be transferred as a function of a sensed operating state of the wheel brake device and / or as a function of the driving speed of the motor vehicle into an operating position in which the cooling air duct is at least partially opened and the cooling air flow is permitted and can further be transferred into an operating position in which the cooling air duct is closed and said cooling air flow is prevented.

[0008] DE 10 2014 215 732 A1 discloses an air guide assembly for a vehicle wheel functionally connected to a braking system. The assembly is arranged in the area in front of the vehicle wheel and projects downwards toward the roadway. The air guide assembly comprises at least one air guide body, at least one baffle lip, and at least one channel designed to direct air toward the braking system.

[0009] WO 2018 / 096 113 A1 discloses an air guiding device for use on the underside of a motor vehicle in front of a vehicle wheel, comprising at least one air guiding body, wherein the air guiding body has at least two air guiding body elements by means of which the width extension of the air guiding body can be changed in the transverse direction of the vehicle.

[0010] DE 10 2014 206 364 A1 discloses an arrangement of a closure element in an opening in a wheel house of a motor vehicle, which serves to cool a brake system. When the closure element is arranged in an opening in a wheel house of a motor vehicle, which serves to cool a brake system, the closure element is made of a flexurally elastic material and is arranged and designed in the opening such that, due to its elasticity, it can be inserted into and / or removed from the opening without causing damage.

[0011] The present invention is based on the object of providing a set for producing a wheel house arrangement for a wheel house of a motor vehicle with which different wheel house variants can be produced.

[0012] To achieve the object underlying the invention, a set for producing a wheel house arrangement for a wheel house of a motor vehicle is proposed, comprising a wheel house liner with a cooling channel, wherein the cooling channel is designed, in an installed state of a wheel house arrangement produced with the set in a motor vehicle, for guiding cooling air to a braking system of the motor vehicle, wherein the wheel house liner has an inlet opening for the cooling channel, wherein the inlet opening is arranged on an underside of the wheel house liner in the installed state of a wheel house arrangement produced with the set, wherein it is further provided that the set comprises a stop body, wherein the stop body can be arranged or is arranged on the wheel house liner in such a way that the inlet opening is completely covered or closed.

[0013] The set thus comprises a wheel house liner which is always designed with a cooling channel, wherein the cooling channel is preferably designed according to the requirements for the cooling performance of the braking system, more particularly for the braking system of a front wheel, of a high-powered motor vehicle.

[0014] According to the invention, the set comprises a thrust body, wherein the thrust body can be or is arranged on the wheel house liner in such a way that the inlet opening is partially or completely covered or closed. By arranging the thrust body on the wheel house liner in the region of the inlet opening, its cross-section can thus be adjusted such that only little or no cooling air is supplied to the braking system of the motor vehicle through the cooling channel of a wheel house arrangement produced with the set when installed. This variant is particularly suitable for vehicles with low engine power which have little or no cooling requirements for the braking system. In a wheel house arrangement in which the thrust body is arranged on the wheel house liner, the drag coefficient, also known as the cW value, is also reduced and, as a result, the energy consumption of the motor vehicle is also reduced.

[0015] For larger or high-powered vehicles, the kit can be used to create a wheel house assembly for a motor vehicle's wheel house in which the thrust body is not positioned at the inlet opening, thus leaving the inlet opening for the wheel house liner's cooling channel uncovered or unblocked. In this version, sufficient cooling air can be directed to the vehicle's braking system when installed.

[0016] The design of the inlet opening on the underside of the wheel house liner provides advantageous cooling air supply to the braking system, particularly for high-powered vehicles.

[0017] In the set according to the invention for producing a wheel house arrangement for a wheel house of a motor vehicle, preferably only a single wheel house liner is provided, which can be used for both variants.

[0018] This reduces the costs for a wheel house arrangement comprising a wheel house liner of a motor vehicle.

[0019] Preferably, the wheel house arrangement is designed for a wheel house for a front wheel of the motor vehicle.

[0020] With further advantage, it can be provided that the starting body comprises a flexible and / or elastic material and / or consists of a flexible and / or elastic material.

[0021] In particular, it can be provided that the flexible and / or elastic material is a plastic.

[0022] With further advantage, it can be provided that the cooling channel is an open cooling channel, in particular a cooling air channel, or a closed cooling channel, in particular a cooling air tunnel.

[0023] The cooling channel can thus be designed as an open cooling channel that is not closed in the circumferential direction, thus being configured somewhat like a cooling air channel formed on the underside of the wheel house liner. Alternatively, the cooling channel can also run entirely within the wheel house liner, penetrating it in the form of a cooling air tunnel or cooling air tube. In this case, the cooling channel is closed in the circumferential direction.

[0024] Preferably, it can be provided that the wheel house liner has a formation which, in the installed state, protrudes in a forward direction of the motor vehicle, wherein the formation at least partially encompasses or forms the cooling channel.

[0025] With further advantage, it can be provided that the formation at least partially encompasses or forms the inlet opening.

[0026] The protruding shape in a forward direction of the vehicle ensures that the beginning of the cooling duct, in particular the inlet opening, is positioned spatially in front of the brake system and the rest of the wheel house liner. This enables better cooling air flow.

[0027] Furthermore, it can be provided that the starting body can be arranged or is arranged on the formation.

[0028] It is further preferably provided that the starting body has a first edge region and that the formation has a second edge region, wherein the first edge region has first connecting means, wherein the second edge region has second connecting means complementary to the first connecting means, wherein the starting body can be connected or is connected to the formation by forming a connection between the first connecting means and the second connecting means.

[0029] The first connecting means of the thrust body and the second connecting means of the molding are particularly designed to enable quick and easy mounting of the thrust body to the wheel house liner. This enables quick and cost-effective production of the wheel house assembly.

[0030] Furthermore, it can be provided that the connection is a screw connection or a snap connection.

[0031] A snap-in connection is particularly advantageous because it allows for fewer manual steps when producing a wheel house assembly from the components of the set.

[0032] It can further advantageously be provided that the formation and / or the thrust body have a substantially triangular, trapezoidal, elliptical, or semicircular basic shape. In principle, any suitable basic shape for the design of the thrust body and / or the formation is conceivable. The basic shape of the thrust body and / or the formation is preferably the shape that it has in the installed state in a top view of the underside of a wheel house assembly manufactured with the set.

[0033] A substantially triangular, trapezoidal, elliptical, or semicircular basic shape is understood to be a basic shape that can be roughly understood as a triangle, trapezoid, ellipse, or semicircle. Deviations from the geometric shape at the corners and / or sides in the form of rounded or curved sections are included in these basic shapes.

[0034] As a three-dimensional body, the thrust block is essentially conical or semi-conical. This means, in particular, that the thrust block, when installed, is narrower in the front area, facing the front of the vehicle, than in the rear area, facing the tire or wheel house liner.

[0035] A further solution to the problem underlying the invention consists in a wheel house arrangement for a wheel house of a motor vehicle, in particular producible or produced with a set as described above, comprising a wheel house liner with a cooling channel, wherein the cooling channel is designed, in an installed state of the wheel house arrangement in a motor vehicle, to guide cooling air to a braking system of the motor vehicle, wherein the wheel house liner has an inlet opening for the cooling channel, wherein the inlet opening is arranged on an underside of the wheel house liner in the installed state, wherein it is further provided that the wheel house arrangement comprises a stop body, wherein the stop body is arrangeable or arranged on the wheel house liner in such a way that the inlet opening is completely covered or closed.

[0036] The wheel house arrangement according to the invention can thus particularly preferably be manufactured using a previously described set, meaning that the wheel house arrangement can be available in two different variants. In a first variant, the stop body can be arranged on the wheel house liner. In this first variant, the stop body at least partially or completely covers or closes the inlet opening. This variant is particularly suitable for vehicles with lower engine power, as these require little cooling air for the braking system. In a second variant, the wheel house liner is provided without a stop body and is then particularly suitable for a motor vehicle with a higher engine power.

[0037] Furthermore, it can be provided that the starting body comprises a flexible and / or elastic material and / or consists of a flexible and / or elastic material.

[0038] It is preferably provided that the flexible and / or elastic material is a plastic.

[0039] In addition, it can be provided that the cooling channel is an open cooling channel, in particular a cooling air channel, or a closed cooling channel, in particular a cooling air tunnel.

[0040] Preferably, the wheel house liner has a protruding shape in a forward direction of the motor vehicle in the installed state, wherein the protrusion at least partially encloses or forms the cooling channel.

[0041] The formation can at least partially encompass or form the inlet opening.

[0042] Furthermore, the starting body can be arranged or arranged on the formation.

[0043] It is preferably provided that the starting body has a first edge region and that the formation has a second edge region, wherein the first edge region has first connecting means, wherein the second edge region has second connecting means complementary to the first connecting means, wherein the starting body can be connected or is connected to the formation by forming a connection of the first connecting means with the second connecting means.

[0044] The connection is preferably a screw connection or a snap connection.

[0045] The formation and / or the starting body can have a substantially triangular, trapezoidal, elliptical or semicircular basic shape.

[0046] A further solution to the problem underlying the invention consists in a motor vehicle with a wheel house arrangement as described above.

[0047] A further solution to the problem underlying the invention consists in providing a method for providing a wheel house arrangement on a motor vehicle, carried out with a set as described above, comprising the steps: - Provision of the wheel house liner, - Arranging the thrust body on the wheel house liner, and - Mounting the wheel house liner with or without thrust body to the vehicle.
