This application claims priority under 35 USC 119 to German Patent Appl. No. 10 2017 104 237.7 filed on Mar. 1, 2017, the entire disclosure of which is incorporated herein by reference.
The invention relates to a wheel house with a wheel house cover, and to a wheel house cover of a motor vehicle.
Motor vehicles have a body that forms wheel houses to accommodate the wheels of the motor vehicle. The wheels with their running gear are accommodated in the wheel houses in a suspended and damped manner and optionally also steerable manner. Wheel house covers may be fastened to a body sheet to form a transition from the wheel house to a wing or side part of the vehicle.
EP 2 423 080 discloses a wheel house with a wheel house cover fastened to a body sheet. Protruding eyelet elements are formed both on the body sheet and on the wheel house cover, and a fastening clip is pushed through the eyelet elements to achieve an interlocking connection between the wheel house cover and the body sheet. Plural eyelet elements are arranged along the wheel house cover to achieve a stable defined arrangement of the wheel house cover on the body sheet.
DE 10 2009 042 845 A1 discloses a wheel house cover that also is fastened to the body sheet by fastening clips. For this purpose, both the body sheet and the wheel house cover have corresponding openings.
A tolerance situation of the wheel house cover of the prior art may cause an undefined, undesired position of the wheel house cover with respect to the body sheet.
It is therefore the object of the invention to provide a wheel house with a wheel house cover, and to provide a wheel house cover of simple design and to ensure a defined position of the wheel house cover relative to the body sheet.
The invention relates to a wheel house cover for a wheel house of a motor vehicle. The wheel house cover has a basic body that is substantially in the form of a segment of a circular ring with a visible side and a rear side. The wheel house cover is fastenable with the rear side to a body sheet such that the visible side is visible. The rear side of the wheel house cover is provided with fastening crosspieces that have a fastening opening and a fastening protrusion. The fastening opening serves for the interlocking connection of the wheel house cover to the body sheet by means of a fastening element, and the fastening protrusion engages in a positioning opening of the body sheet to position the wheel house cover relative to the body sheet. As a result, the wheel house cover can be fastened to the body sheet in a secure and positionally correct manner. The fastening protrusion can provide at least a slight pretension between the wheel house cover and the body sheet to improve the positioning.
The fastening protrusion may have a T-shape formed by three protruding ribs. Two of the ribs may define a surface or plane and the third rib is perpendicular or normal thereto. As a result, the first and second ribs can be positioned against an edge of the positioning opening, and the third rib can be supported on an opposite edge.
At least one rib may taper from a base on the wheel house cover toward the free end of the fastening protrusion to produce a ramp that can bring about bracing of the wheel house cover. The third rib also is referred to as a coordinating rib because it produces a pretension between the wheel house cover and the body sheet.
The fastening opening and the fastening protrusion may be adjacent to each other on the fastening crosspiece. As a result, in addition to the fastening of the wheel house cover by means of the fastening crosspiece, the bracing is undertaken directly adjacent to the fastening. This makes it possible to avoid or reduce unintentional effects due to an expansion of the wheel house cover.
Spacer ribs may be provided on the fastening crosspiece. The spacer ribs advantageously may be arranged adjacent to the fastening opening and/or to the dome. The spacer ribs may be placed against the body sheet, and therefore a defined distance between the body sheet and the wheel house cover is predetermined. The geometrical arrangement of the spacer ribs assures a uniformly distributed transmission of force between the wheel house cover and the body sheet.
The spacer ribs may be of rectilinear design, and individual spacer ribs or all of the spacer ribs may be parallel and/or perpendicular to one of the protruding ribs of the fastening protrusion. Thus, good distribution of forces can be achieved. The spacer ribs also form a framework for stabilizing the wheel house cover.
One spacer rib may be between the fastening protrusion and the fastening opening and may be parallel to the first and second ribs of the fastening protrusion.
The spacer ribs may have a first height (h) and the fastening protrusion may have a second height (H). The second height (H) may be greater than the first height (h). The effect achieved by this is that the fastening protrusion always engages in the positioning opening, even if the spacer ribs lie in contact against the body sheet.
The basic body may be of L- or C-shape. The basic body of the wheel house cover can thus be inserted in a drawn-back region of the body sheet, and therefore a type of joint of zero joint is formed between the body sheet and the wheel house cover.
The invention also relates to a wheel house with the above-described wheel house cover. The wheel house may have a body sheet with a region that is substantially in the shape of a segment of a circular ring and has plural opening pairs. The opening pairs have a fastening opening and a positioning opening. A circular ring does not strictly have to be provided for the feature of the region in the shape of a circular ring. Certain deviations therefrom should also be regarded as such a region.
The body sheet may be tapered so that it at least partially accommodates the wheel house cover. The effect achieved by this is that the wheel house cover can be arranged approximately flush or with an excess length or recess with respect to the wing or side part. The recess or the excess length can optionally also only be small.
The invention is explained in detail below using an exemplary embodiment with reference to the drawing.
The wheel house 1 has a body sheet 5, which, for example, forms the wing or a side part. However, the body sheet 5 can be formed separately therefrom.
As shown in
A circular ring does not strictly have to be perfectly circular, and certain deviations therefrom should also be regarded as such a region.
The fastening openings 8 cannot be seen directly in
The body sheet 5 is tapered in an approximate s shape for at least partially accommodating the wheel house cover 2, as shown in
The invention also relates to a wheel house cover 2 for a wheel house 1 of a motor vehicle. The wheel house cover 2 is formed with a basic body 13 that is substantially in the shape of a segment of a circular ring and has an outer side 14 and an inner side 15. The wheel house cover 2 can be fastened with the inner side 15 facing a body sheet 5 so that the outer side 14 is visible.
At least one of the rib 20, 21 and/or 22 may taper from a base 23 on the wheel house cover 2 toward the free end 24 of the fastening protrusion 18 to produce a ramp that can bring about bracing of the wheel house cover 2 when the fastening protrusion 18 is inserted into the positioning opening 19. The third rib 22 also is referred to as a coordinating rib because it produces a pretension between the wheel house cover 2 and the body sheet 5.
The fastening opening 17 and the fastening protrusion 18 are adjacent to each other on the fastening crosspiece 16. In addition to the fastening of the wheel house cover 2 by means of the fastening crosspiece 16, the bracing thereby also is provided directly adjacent to the fastening. It is thereby possible to avoid or reduce unintentional effects because of an expansion of the wheel house cover.
Spacer ribs 25 protrude from the fastening crosspiece 16 in the direction toward the body sheet 5 as shown in
As illustrated in
The spacer ribs 25 have a first height (h) and the fastening protrusion 18 has a second height (H) that is greater than the first height (h). Thus, the fastening protrusion 18 always engages in the positioning opening 19, even if the spacer ribs 25 contact the body sheet 5.
The basic body 13 is of C-shape, as shown in
The fastening crosspiece 16 also is approximately C-shaped, and therefore a clearance remains between the fastening crosspiece 16 and the wheel house cover 2 to accommodate the fastening element 10.
