    A WHEEL HOUSING FOR A VEHICLE AND A VEHICLE WITH SUCH WHEELHOUSING TECHNICAL FIELDThe invention relates to a wheel housing for a vehicle, and a vehicle with such awheel housing according to the appended claims.
    BACKGROUND AND PRIOR ART Wheels of vehicles, such as cars and heavy goods vehicles, require attention when itcomes to how the wheels interact with the driving surface as well as the connectionto the chassis of the vehicle, which occurs at the wheel housing of said vehicle. Thewheel housing partly covers the wheels of the vehicle allowing them to perform ac-tions such as the driving rotation and turning. The wheel housing further needs toprotect the other parts of the chassis from the dirt, moisture and potential debrisgenerated by the wheels when interacting with the driving surface. Wheel housingsare therefore generally provided with mudguards which covers parts of a circumfer-ential arch around the wheel. l/ludguards thereby act as a shield from incoming dirtand moisture being flung up towards the chassis and the cabin when the wheel ro-tates. However, such mudguards cannot be positioned to close to the circumferenceof the wheel as the wheel must have room for the movement based on the suspen-sion of the wheel. A gap is therefore always present between the wheel and themudguard. This gap is not ideal from an aerodynamic point of view and it is thereforedesired to at least partly cover said gap. Also, dirt, moisture and potential debrisgenerated by the wheels may be flung up towards the chassis and the cabin due tosaid gap. As the size of a wheel might vary for the same type of mudguard due tomanufacturing reasons, the different sizes of gaps may be covered by an additionalelement called a trim panel. A trim panel of correct size may thereby be mounted toa mudguard to bridge the described gap instead of manufacture the mudguards tocover the gap directly.
    Such a trim panel must be securely attached to the mudguard to avoid falling off as a result of bumps in the road or long exposure of driving the vehicle. The attachment of the two elements must therefore by reliable over a long period of time. The mountingprocess of a trim panel to a mudguard as known in the art is usually performed bymeans of different types of fastening elements such as screws, bolts or clasps orsimilar. This may lead to a time consuming mounting which therefore also increases costs for the manufacturing of such vehicles.
    SUMMARY OF THE INVENTION Despite prior art there is therefore a need to develop a wheel housing comprising amudguard and a trim panel which are easy and fast to assemble. There is also aneed to develop a wheel housing comprising a mudguard and a trim panel which arereliable and securely attached to each other. Furthermore, there is a need to developa wheel housing comprising a mudguard and a trim panel wherein the mounting ofthe trim panel to the mudguard may be performed without additional separate fas-tening elements and without the use of tools to achieve a fast and cost effective mounting of the wheel housing.
    An object of the present invention is thus to provide a wheel housing comprising amudguard and a trim panel which are easy and fast to assemble. Another object is toprovide a wheel housing comprising a mudguard and a trim panel which are reliableand securely attached to each other. A further object of the invention is to providewheel housing comprising a mudguard and a trim panel wherein the mounting of thetrim panel to the mudguard may be performed without additional separate fasteningelements and without the use of tools to achieve a fast and cost effective mounting of the wheel housing.
    The herein mentioned objects are achieved by a wheel housing comprising a mud-guard and a trim panel and a vehicle with such a wheel housing according to the in- dependent claims.
    According to an aspect of the invention a wheel housing for a vehicle, in particular aheavy goods vehicle is provided. The wheel housing comprises a mudguard and atrim panel. The mudguard is arranged to at least partly cover a portion of a wheel ar-ranged in said wheel housing, and the trim panel is arranged to at least partly cover a gap defined by a distance between a circumference of the wheel and the mud-guard. Further, the mudguard and the trim panel are arranged to be interlocked bymeans of a snap lock arrangement comprising a first connection element and a sec-ond connection element, wherein one of the connection elements is arranged on themudguard and the other corresponding connection element is arranged on the trim paneL This has the advantage that the mudguard and the trim panel can be attached toeach other without the need to use tools by means of the snap lock arrangement.This further has the advantage that the attachment of the trim panel to the mudguardis fast and therefore cost effective to perform. The cost of such an assembly is fur-ther lowered by means of eliminating additional fastening elements, which is benefi- cial for a manufacturing process of such a wheel housing.
    According to another aspect of the invention the first connection element comprisestwo extending first ribs, an upper first rib and a lower first rib, and the second con-nection element comprises one extending second rib, wherein the second rib is ar-ranged to be inserted between the two first ribs so as to establish upper and lowercontact surfaces between the two first ribs and the second rib.
    This has the advantage that the connection elements are simple in their design and therefore easy to both manufacture and use.
    According to yet another aspect of the invention the contact surfaces between thefirst and second ribs comprises snap locking means comprising a plurality of recess-es and corresponding extending projections, arranged to interlock with each other.
    This has the advantage that the snap locking means are designed in a non-complexway which provides an easy and cost effective arrangement to manufacture. Fur-thermore, as the contact surfaces and therefore the snap locking means are distrib-uted on both upper and lower sides of the intermediate extending second rib the in-terlocking of the mudguard and the trim panel is achieved in a secure and reliable manner.
    According to a further aspect of the invention each projection comprises a s|antingfront surface and a Iocking hee|, wherein an angle of the Iocking hee| is in the rangeof about 70°to about 90° relative to the rib whereon it is situated.
    This has the advantage that the s|anting front surface provides an easy way for theextending ribs to be fitted together as the contact surfaces will be established andslide upwards said s|anting surface. Thereafter the ang|ed Iocking hee| provides asecure attachment of the projection within the corresponding recess which is benefi- cial as the interlocking of the two snap Iocking means thereby is established and up- held in a likewise secure manner.
    According to an even further aspect of the invention each projection may be U- shaped, wherein the Iocking hee| is arranged at a base of the U-shape.
    This has the advantage that a less bulky projection can be provided due to no mate-rial being needed within the U-shape. This is beneficial as it brings down the manu-facturing costs while still providing a stable projection which can abut edges of eachcorresponding recess in which each projection is inserted by means the outer sidesof the U-shape.
    According to an aspect of the invention the second rib is a staggered rib, comprisingat least one upper portion and at least one lower portion, wherein the at least oneupper portion comprises upper contact surfaces between the upper first rib and thesecond rib and the at least one lower portion comprises lower contact surfaces be-tween the lower first rib and the second rib.
    This has the advantage that the staggered shape of the second rib provides me-chanical stability using less material compared to a thicker flat rib. This is beneficialas it brings down manufacturing costs for the snap lock arrangement. A further ad-vantage is that the upper and lower portions of the staggered rib are easier to flexcompared to if the second rib would be solid and extending from the upper to thelower first rib. When a staggered rib is being inserted between the two first ribs theupper portion may flex downwards and the lower portion may flex upwards duringthe initiated interlocking of the snap lock arrangement. Thus the total flex needed is divided between the first and second ribs which lower the mechanical stress on thetwo first ribs. Thereby the interlocking of the snap lock arrangement is easier to initi-ate without diminishing the mechanical integrity of the first two ribs.
    According to another aspect of the invention the two first ribs are extending longerthan the second rib extends, and wherein the first ribs further comprises at least oneinner protrusion, arranged to bridge the two first ribs, wherein a front end of the sec-ond rib is arranged to abut against said protrusion when the second rib is fully insert-ed between the two first ribs.
    This has the advantage that the fitting of the first two ribs and the second rib is easierto manage than compared to if the first and second ribs having an equal length. Astolerances are always an issue when manufacturing form fitted mechanical compo-nents, it is easier to manage such fit tolerances by means of limiting the fit tolerancesto the inner protrusions rather than having the front end of the second rib being fullyin contact with a surface being intermediate of the two first ribs. lf the fit of the twofirst ribs and the second rib is not perfect after manufacturing of the snap lock ar-rangement, a following process step adjusting the fit of the components is faster andtherefore more cost effective if less material needs to be exposed to a follow-up pro-cess step.
    According to yet another aspect of the invention the first connection element is ar-ranged on an outer edge of the mudguard and the second connection element is ar-ranged on an inner edge of the trim panel.
    This has the advantage that first connection element which requires more material tomanufacture is arranged on the mudguard. This is beneficial as the mudguards, be-ing more complex in their design may be used for several types and models ofwheels. To adjust for the different sizes and shapes of gaps, being the result of dif-ferent shapes and sizes of wheel mounted in a specific mudguard, a different trimpanel may be mounted to said mudguard. As the trim panels are a less complex el-ement compared to the mudguard, it is more cost effective to change trim panel thanto change a mudguard. lt is thus further cost effective to manufacture the trim panelwith the one second rib as the manufacturing processes of the various different trim panels are made less complex and requires less materials to be manufactured. Also,if for example the trim panels are moulded, a smooth surface opposite to the surfaceprovided with the projection of the trim panel is easier to achieve when only one rib,the second rib, is arranged on the trim panel due to a lesser mass of material solidi- fying behind said surface.
    According to another aspect of the invention the first connection element is arrangedon an inner edge of the trim panel and the second connection element is arranged on an outer edge of the mudguard.
    This has the advantage that the outer edge of the mudguard may be designed withsmaller dimensions and thus less material is needed to manufacture the mudguard.This is beneficial for application where the dimensions of the mudguard are of im- portance, such might be the case for smaller types of vehicles.
    According to a further aspect of the invention a vehicle is provided, which vehicle comprises a wheel housing according to the present invention.
    This has the advantage that a vehicle with a wheel housing is provided, which wheelhousing is cost effective to manufacture and fast and easy to assemble, without the need for tools for the assemble process.
    BRIEF DESCRIPTION OF THE DRAWINGSBelow is a description of, as examples, preferred embodiments of the invention with reference to the enclosed drawings, in which: Figure 1 schematically illustrates a vehicle provided with a wheel housing comprising a mudguard and a trim panel according to the invention, Figure 2 schematically illustrates a perspective view of a mudguard provided with afirst connection element comprising two extending first ribs according to the inven- tion, Figure 3 schematically i|ustrates a perspective view of a trim panel provided with asecond connection element comprising one extending second rib according to the invenfion, Figure 4 schematically i|ustrates a plan view of snap lock arrangement comprising arecess and a projection, interlocked with each other according to the invention, Figure 5 schematically i|ustrates a cross-sectional side view of a recess and a pro- jection, interlocked with each other according to the invention, and Figure 6 schematically i|ustrates a cross-sectional side view of first and second con-nection elements interlocked with each other according to the invention.
    DETAILED DESCRIPTION OF PREFERRED El/|BODl|/IENTS OF THE lNVENTlONFigure 1 schematically i|ustrates a vehicle 1 provided with a wheel housing 3 com-prising a mudguard 5 and a trim panel 7 according to the invention. The vehicle 1shown in figure 1 further comprises a chassis 9, a cabin 11 and three wheels 13. lnthis example only the front wheel 13 is covered with a mudguard 5 and trim panel 7according to the invention but all three wheels 13 can of course have such mud-guards 5 and trim panels 7. The mudguard 5 is not directly seen in figure 1 as it islocated behind, and therefore covered by, the trim panel 7. The main function of themudguard 5 and the trim panel 7 is to act as shields for the chassis 9 and the cabin11, shielding them from dirt and water being flung up from the road or ground bymeans of the driving rotation of the wheel 13. The trim panel 7, being the elementplaced the furthest out towards the surrounding environment, further has the addi-tional function of affecting the aerodynamics of the vehicle 1. As the suspension (notshown) of the vehicle 1 holds the wheel 13 at a distance from the mudguard 5, creat-ing a gap between the two, the airflow around the vehicle 1, and therefore the wheel13, generated by the driving speed, may flow into said gap and cause turbulenceand resistance. The shape and design of the trim panel 7 may therefore be used tolower said turbulence and resistance to in turn lower the fuel consumption of the ve-hicle 1. Furthermore, as the trim panel 7 is the object seen from outside of a vehicle1, it is also desirable for the trim panel 7 to have a pleasant design from an esthetical point of view.
    Figure 2 schematically illustrates a perspective view of a mudguard 5 provided with afirst connection element 15 comprising of two extending first ribs 17 according to theinvention. The mudguard 5 depicted in figure 2 is arranged to cover a portion of awheel 13, as shown in figure 1, when said wheel 13 is mounted in the wheel housing3. Thereby the mudguard 5 will act as a shield for mud, dirt and water being f|ungagainst the chassis 9 and the cabin 11 situated above the mudguard 5, as shown infigure 1, when the wheel housing 3 is assembled to said chassis 9. The mudguard 5may be of another shape and size than depicted to cover a longer or a shorter archover a wheel 13 without deviating from the inventive concept of the invention. Asseen in figure 2, the two extending first ribs 17 are arranged on an outer edge 19 ofthe mudguard 5. Further, the two extending first ribs 15, being an upper first rib 17'and a lower first rib 17", comprises first snap locking means 21 in the form of a plu-rality of recesses 23 which are to accommodate respective second snap lockingmeans in the form of projections situated on a respective second connection ele-ment, wherein the projections are arranged to fit said recesses 23 (a second connec-tion element comprising projections is shown in figure 3). The recesses 23 are in thisexample of the invention through holes in the two first ribs 17 but may also be inden- tations or similar in said first ribs 17.
    Figure 3 schematically illustrates a perspective view of a trim panel 7 provided with asecond connection element 25 comprising one extending second rib 27 according tothe invention. The trim panel 7 depicted in figure 3 is shaped in regards to size andshape to fit to the mudguard seen in figure 2. The second connection element 25 inthe form of the extending second rib 27 is in this example of the invention a stag-gered rib. The staggered rib in this example comprises a plurality of upper portions29 and a plurality of lower portions 31. Each upper portion 29 comprises an uppercontact surface 33, arranged to abut an upper first rib 17” and each lower portion 31comprises a lower contact surface 35, arranged to abut a lower first rib 17", whenthe second rib 27 is being inserted between two first ribs 17”, 17", such as the upperand lower first ribs 17”, 17" shown in figure 2. Further, each upper and lower contactsurfaces 33, 35 of the second rib 27 comprises second snap locking means 37 in theform of an extending projection 39, the projections 39 of the upper portions 29 ex-tending in a direction essentially outwards and towards a corresponding recess 23 of the upper first rib 17” of the mudguard 5 as seen in figure 2. The term outwards ismeant to be viewed as outwards in regards to the arched shape of the wheel hous-ing. Respectively, the projections 39 of the lower portions 31 extend in a directiontowards corresponding recesses 23 arranged in the lower first rib 17", shown in fig-ure 2. By having a staggered shape, the second rib 27 will further be more flexiblewithout losing mechanical stability. Both the upper and lower portions 29, 31 will beable to flex inwards at the same time as the two first ribs 17 flex outwards when thefirst and second snap locking means 15, 25 are coupled together. Thereby the flexneeded to slide the projections 39 into the recesses 23 is divided by the first andsecond ribs 17, 27 resulting in that no rib alone must be able to flex the neededamount. For a more detailed description of a snap lock arrangement 41 comprisingthe first and second snap locking means 21, 37, further see the description with ref-erence to figures 4-6. Furthermore, the staggered shape gives mechanical stability tothe second rib 27 which hinders the rib 27 from bending or breaking when exposedto forces acting on the assembled wheel housing 3. The staggered shape of thesecond rib 27 may vary from having rounded bends to have more sharp angledbends in the rib 27 without deviating from the inventive concept of the invention. Thetotal number of upper and lower portions 29, 31 may also vary depending on the sizeof the mudguard 5 and the trim panel 7, which naturally may vary depending on thesize of a vehicle 1 for which they are manufactured. The staggered rib in the embod- iments herein may also be referred to as a corrugated rib.
    Both the mudguard 5 and the trim panel 7 may be made of a polymer material suchas a strong and wear resistant plastic material, but may also be made of metallic orcomposite materials. When made of a plastic material, the mudguard 5 and the trimpanel 7 are usually moulded or casted wherein the non-complex design of the snaplock arrangement 41 according to the invention is beneficial as the designs are easy to implement into moulds and casts.
    When assembling the mudguard 5 shown in figure 2 and the trim panel 7 shown infigure 3, the snap lock arrangement 41, comprising of the first and second ribs 17, 27with the recesses 23 and projections 39 respectively, is interlocked by inserting thesecond rib 27 in between the two first ribs 17. The projections 39 of the second rib 27 further comprises a slanting front surface (shown in more detail in figure 5) which assists in getting the two first ribs 17 to slide over the projections 39 until the recess-es 23 align with the projections 39 and the snap lock arrangement 41 interlocks.Such an assembly is thereby achieved, which is securely attached and mechanicallystable, and is achievable without the use of additional separate fastening elements.Furthermore, the assembly of the mudguard 5 and the trim panel 7 is performedwithout the need for tools which makes the process fast and easy to perform. lt should be noted the examples of the invention shown in figure 2 and 3 are de-signed with the first connection element 15, being the two first ribs 17, arranged onthe mudguard 5 and the second connection element 25, being the second rib 27, ar-ranged on the trim panel 7. As should be obvious, the first connection element 15may instead be arranged on the trim panel 7, and the second connection element 25consequently arranged on the mudguard 5 without deviating from the inventive con-cept of the invention. Similarly, according to the examples shown in figure 2 and 3,the projections 39 and the recesses 23 of the snap lock arrangement 41 are ar-ranged on the second and the two first ribs 27, 17 respectively. The projections 39may instead be arranged on the two first ribs 17, and the recesses 23 may be ar-ranged on the second rib 27, without deviating from the inventive concept of the in-vention. For convenience, all examples shown and described within the descriptionare however shown as in figure 2 and 3, but it should be realized that all possiblecombination of the above described arrangements may be used for the wheel hous- ing 3 according to the invention.
    Figure 4 schematically illustrates a plan view of a snap lock arrangement 41 com-prising a recess 23 and a projection 39, interlocked with each other according to theinvention. The projection 39 shown in figure 4 comprises two slanting front surfaces43 and a locking heel 45. The slanting front surfaces 43 are arranged to push thefirst and second ribs 17, 27 away from each other when the snap lock arrangement41 is being assembled. When the second rib 27 is fully inserted between the two firstribs 17, the projections 39 falls into their corresponding recesses 23 and the inter-locking of the snap lock arrangement 41 is thereby established. The projection 39shown in figure 4 may be U-shaped, wherein the locking heel 45 is arranged at thebase of the U-shape. Thereby the total amount of material needed to manufacturethe projection 39 is lowered while still ensuring a large locking heel 45 for the ar- 11 rangement. As the assembly of a mudguard 5 and a trim panel 7 using a snap lockarrangement 41 with a plurality of projections 39 and recesses 23 as the ones shownin figure 4 needs to be held together tightly by means of a snug fit, the shape of therecess 23 is designed to correspond to the circumference of the projection 39. Whenassembled the locking heel 45 is in direct contact with a front edge 47 of the recess,and side walls 49 of the projections are in direct contact with, or close to, side edges51 of the recess. Thereby the projection 39 is hindered from moving when it is in-serted into, and interlocked with, its respective recess 23. The U-shape further hasan additional advantage in the case of the wheel housing 3 being moulded from aplastic material when manufactured. A too large mass of liquid plastic material solidi-fying may risk shrinking too much and thereby also affecting the shape of the surfaceof the rib directly opposite of the projection. By using a U-shape the amount of mate-rial used for a projection 39 is lowered and thus the issue of changing shape duringthe solidification of the plastic is reduced. This is beneficial as the end product ismore in line with its designed shape and the tolerances of the snap lock arrangement 41 may thus be designed smaller.
    Figure 5 schematically illustrates a cross-sectional side view of a recess 23 and aprojection 39, interlocked with each other according to the invention. Figure 5 furthershows an outer edge 19 of a mudguard 5 whereupon a first connection element 15,being two first ribs 17, is arranged. Even further figure 5 shows an inner edge 53 of atrim panel 7 whereupon a second connection element 25, being a second rib 27, isarranged. The two connection elements 15, 25 thereby constitute a snap lock ar-rangement 41 for establishing a connection between the mudguard 5 and the trimpanel 7. The cross-section is viewed a direction along the elongation of a mudguard5 assembled with a trim panel 7 by means of said first and second ribs 17, 27. Thesecond rib 27 is a staggered rib, wherein the cross section is taken through one ofthe upper portions 29 of said staggered second rib 27, comprising an upper contactsurface 33 to the upper first rib 17”. The projection 39 arranged on the upper portion33 of the second rib 27 comprises a slanting front surface 43, having an angle oi ofabout 45° as shown in figure 5. This angle might differ but may be an acute angleproviding an angled plane for the adjacent first rib 17' to slide upon. Furthermore, theprojection 39 comprises a locking heel 45, wherein an angle ß of the locking heel 45is in the range of about 70°to about 90° relative to the rib whereon it is situated, be- 12 ing the second rib 27 in this example. The locking heel 45 is thereby angled slightlybackwards, towards the inner edge 53 of the trim panel 7, to provide a secure inter-locking of the projection 39 and the recess 23 where the risk of the snap lock ar-rangement 41 unlocking is lowered. As is shown in figure 5, the two first ribs 17 arelonger than the second rib 27, and the first two ribs 17 further comprises an innerprotrusion 55, arranged to bridge the two first ribs 17. When the snap lock arrange-ment 41 is interlocked by means of fitting the projections 39 into their respective re-cesses 23, a front end 57 of the second rib 27 is arranged to abut against said innerprotrusion 55 when the second rib 27 is fully inserted between the two first ribs 17.Thereby a tight fit with small tolerances is easier to achieve as the abutment of thefront end 57 of the second rib 27 towards to inner protrusion 55 is constituted by asmaller surface area than if the first and second ribs 17, 27 would have an equallength. lf the first and second ribs 17, 27 would have equal length, any small error inthe shape of the surface between the two first ribs 17 could then potentially misalignthe projections 39 and the recesses 23 due to not being able to insert the second rib27 fully between the two first ribs 17. By have the abutment surfaces being smallerand focused on inner protrusions 55, a smaller area needs to be inspected and ad-justed by a suitable follow-up process step if it would show that the snap lock ar-rangement 41 would not fit perfectly. The inner protrusions 55 are therefore benefi-cial from a manufacturing point of view, which leads to a cost efficient design of awheel housing 3 comprising mudguard 5 and trim panel 7 comprising such a snaplock arrangement 41. A snap lock arrangement 41 according to the invention mayhave a single inner protrusion 55 or a plurality of inner protrusions 55. Depending onthe size of the wheel housing 3 being manufactured the design may easily be alteredin regards of the number on such inner protrusions 55 without deviating from the in- ventive concept of the invention.
    Figure 6 schematically illustrates a cross-sectional side view of first and second con-nection elements 15, 25 interlocked with each other according to the invention. Thecross section shown in figure 6 is taken through the interlocked projections 39 andrecesses 23 of the first and second connection elements 15, 25, and is viewed in adirection from the trim panel 7 towards the mudguard 5. Figure 6 shows in more de- tail how the staggered second rib 27 alternates up and down comprising upper and 13 lower portions 29, 31 whereupon the respective projections 39 are arranged on theupper and lower contact surfaces 33, 35 between the first and second ribs 17, 27.
    As should be realized, the components and features specified above may within theframework of the invention be combined between the different embodiments speci-fied.
