MOTOR VEHICLE WITH ROOF SPOILER

Description

[0001] The invention relates to a motor vehicle, preferably a commercial vehicle, with a roof spoiler.

[0002] Motor vehicles, especially trucks, can have a height-adjustable roof spoiler. The height adjustment allows the roof spoiler to be aligned relative to the front upper edge of a loading body, semitrailer, or trailer. The height adjustment is traditionally performed manually on the rear wall of the truck's cab.

[0003] Motor vehicles can be equipped with a windshield cleaning system. The windshield cleaning system can include cleaning nozzles, a pump, and a tank. The cleaning nozzles are directed at the windshield and can be supplied with cleaning fluid from the tank by the pump. Space must be provided for the tank. Easy access to the tank for filling is also advantageous.

[0004] Conventional brackets for height-adjustable roof spoilers are known, for example, from EP 2 020 366 A2 and EP 1 055 589 A2.

[0005] Regarding the state of the art, reference is also made to DE 10 2014 017 732 A1, which discloses a tractor with two lateral wind deflectors and a fluid tank, preferably a reducing agent tank, located therebetween.

[0006] From US 4,904,015 A, a tractor and a trailer are known which are coupled together in a tandem towing relationship. An air deflector system is attached to the tractor to aerodynamically reduce the air resistance of such a combination by enclosing a space between a cab of the tractor and the trailer. A bracket is attached to a support device of the tractor. An upper air fairing is movably attached to the support device and extends from the top of the cab to the top of the trailer. Two side fairings are movably attached to the support device and extend from the rear of the cab to the trailer, the side fairings mate with the upper fairing. Means is provided for moving the fairings from one position to another depending on the alignment between the trailer and the tractor.

[0007] WO 2007 / 090172 A2 discloses an air shield comprising a sidewall assembly pivotally connected to each rear edge of a tractor sidewall, and an actuation assembly. The actuation assembly includes a hub pivotally engaged with the tractor frame, the hub being disposed between a cab and a fifth wheel of the tractor. The actuation assembly further includes a lever having an adjustable length engaging the hub at a first end and the sidewall assembly at a second end. The actuation assembly further includes a spring having a first end connected to the sidewall assembly and a second end connected to the tractor frame between the hub and the rear of a trailer frame.

[0008] US 4,779,915 A discloses an air foil system for removably and adjustably mounting to a tractor frame behind the cab for reducing the aerodynamic drag experienced by a trailer pulled by the tractor. The air foil system comprises an upright support member having at its base fasteners adapted to removably secure the support member to the tractor frame behind the cab, the support member having a transverse dimension approximately equal to the width of the cab. The air foil system further comprises an air foil adjustably mounted on top of the support member, the air foil being adapted to extend over the cab. The air foil system further comprises an adjustable side wall mounted at each end of the support member, each side wall extending downwardly from the top of the support member toward the base.Each side wall has a height that is greater than its width.

[0009] US 6,428,084 B1 discloses a fuel-efficient tractor-trailer system for improving the fuel consumption of a tractor-trailer combination by reducing the drag that occurs in the area between the rear of the tractor and the front of the trailer. The fuel-efficient tractor-trailer system features an improved roof extension that automatically raises when the tractor is shifted into reverse, as well as an improved wheel mechanism that assists the sliding of the side extensions around the ends of the trailer when the tractor and trailer turn.

[0010] The invention is based on the object of creating an alternative and / or improved motor vehicle with a roof spoiler, and preferably additionally with a windscreen cleaning system.

[0011] The problem is solved by the features of the independent claim. Advantageous further developments are specified in the dependent claims and the description.

[0012] According to one aspect, a motor vehicle, preferably a commercial vehicle (e.g., a truck), is disclosed. The motor vehicle has a body and an outer side panel arranged on a longitudinal outer side of the motor vehicle and connected to the body (e.g., directly or indirectly) so as to be movable, preferably pivotable, between a closed position and an open position. The motor vehicle has a (e.g., pivotable) roof spoiler and an (e.g., manual) adjustment device by means of which the roof spoiler is height-adjustable. When the outer side panel is in its closed position, the adjustment device is concealed behind the outer side panel. When the outer side panel is in its open position, the adjustment device is accessible from the outside.

[0013] This makes the adjustment mechanism particularly easy to access. At the same time, the adjustment mechanism is protected and visually appealingly located behind the outer panel.

[0014] According to the invention, the body has a longitudinal side wall, and the adjusting device is arranged and / or fastened to the longitudinal side wall. Preferably, the longitudinal side wall can be aligned parallel to a longitudinal axis of the motor vehicle and / or can be concealed by the outer side panel in the closed position of the outer side panel and accessible from the outside in the open position of the outer side panel.

[0015] In a further embodiment, the adjustment device comprises a (e.g., vertically oriented) rail by means of which the roof spoiler is height-adjustable. The rail can preferably be designed as an elongated hole and / or have several superimposed projections (e.g., serrated, claw-shaped, or tooth-shaped) to which the roof spoiler can be detachably attached indirectly (e.g., by means of an elongated connecting element), preferably by means of a screw connection.

[0016] In a further exemplary embodiment, the motor vehicle further comprises an elongated (e.g., rod-shaped, tubular, or beam-shaped) connecting element that connects the roof spoiler to the adjustment device in a height-adjustable manner and is preferably pivotably connected to the roof spoiler. Optionally, the motor vehicle can further comprise a trim part arranged between the roof spoiler and the outer side panel, wherein the elongated connecting element is arranged at least partially concealed behind the trim part. Thus, the entire adjustment mechanism for the roof spoiler can be arranged in a manner that is not visible from the outside, protected, and does not negatively impact the aerodynamics of the motor vehicle.

[0017] In one embodiment, the body has a roof with a recess (e.g., a roof ditch), and a leading edge of the roof spoiler dips into the recess as the roof spoiler is raised, e.g., increasingly. This can improve airflow to the roof spoiler.

[0018] In one embodiment, the roof spoiler can be adjusted to a substantially vertical orientation for installation or removal using the adjustment device. This can, for example, allow for installation and removal without having to dismantle a vehicle's cargo area.

[0019] In a further development, the recess extends across the entire width of the roof. Preferably, a bottom surface of the recess can be curved, bent, and / or slope down toward both outer longitudinal sides of the vehicle (or have a gradient). This allows water to drain away easily and does not remain on the roof.

[0020] In one embodiment, the motor vehicle further comprises a windshield washer system (e.g., with a cleaning nozzle for a windshield and / or a headlight lens) with a washer fluid tank and a filler neck for filling the washer fluid tank. When the outer side panel is in the closed position, the filler neck is concealed behind the outer side panel, and when the outer side panel is in the open position, the filler neck is accessible from the outside. This allows the filler neck to be concealed from the outside, protected, and positioned in a way that does not negatively impact the aerodynamics of the motor vehicle. Several functions can thus be concealed behind the outer side panel. This also opens up new possibilities for arranging the washer fluid tank.

[0021] In a further development, the filler neck is arranged and / or fastened to the longitudinal side wall, preferably in an opening in the longitudinal side wall, preferably below the adjusting device.

[0022] In a further embodiment, the cleaning fluid tank is accessible and / or mountable (e.g., installable, removable, replaceable) from underneath the vehicle. This simplifies the installation and, if necessary, replacement of the cleaning fluid tank.

[0023] In one embodiment, the cleaning fluid tank is arranged at least partially in a section between an inner fender of the motor vehicle and an outer fender of the motor vehicle. Alternatively or additionally, the cleaning fluid tank is arranged behind a door of the motor vehicle with respect to a forward direction of travel of the motor vehicle. Alternatively or additionally, the cleaning fluid tank is arranged inside on or from a rear wall of the body. Thus, the cleaning fluid tank can advantageously be arranged in a previously unused space in the body.

[0024] In a further embodiment, the motor vehicle further comprises at least one tool (e.g. towing eye, wiper rod, wheel nut wrench, car jack), at least one container and / or at least one storage compartment which is concealed by the outer side panel in the closed position of the outer side panel and is accessible from the outside in the open position of the outer side panel.

[0025] In one embodiment, the outer side panel can be unlocked and / or moved from the closed position by means of a Bowden cable accessible within the body.

[0026] In a further embodiment, the body is designed as a cab body of a truck.

[0027] In one embodiment, the outer side panel is designed as a side flap.

[0028] In a further embodiment, the outer side panel is arranged in a closed position at an angle obliquely outwards to a longitudinal axis of the motor vehicle, so that preferably a rear edge of the outer side panel is aligned with a side wall of a loading structure of a trailer or semi-trailer of the motor vehicle, preferably substantially flush.

[0029] In one embodiment, the outer side panel is arranged above an outer fender and / or a front axle of the motor vehicle.

[0030] In a further embodiment, the outer side panel extends between an outer fender of the motor vehicle and a roof of the motor vehicle.

[0031] In one embodiment, the outer side panel can be pivoted from the closed position backwards into the open position with respect to a forward direction of travel of the motor vehicle.

[0032] In a further embodiment, the outer side panel has a straight rear edge and a front edge that is at least partially curved with respect to a forward direction of travel of the motor vehicle.

[0033] In a further embodiment, the motor vehicle has a door (e.g., driver's door or passenger door) that is movably connected to the body. The outer side panel is arranged behind the door with respect to a forward direction of travel of the motor vehicle.

[0034] The above-described preferred embodiments and features of the invention can be combined with one another as desired. Further details and advantages of the invention are described below with reference to the accompanying drawings. They show: Figure 1 shows a side view of a front section of an exemplary motor vehicle; Figure 2 shows a further side view of the front section of the exemplary motor vehicle with a pivoted-up outer side panel; Figure 3 shows a detailed view of a detail A from Figure 2; Figure 4 shows a horizontal sectional view through the outer side panel of the motor vehicle at the level of a lower hinge, wherein the outer side panel is shown in an open position and a closed position; Figure 5 shows a further horizontal sectional view through the outer side panel of the exemplary motor vehicle at the level of a locking device, wherein the outer side panel is shown in an open position and a closed position; Figure 6 shows a rear view of a driver's side of the exemplary motor vehicle; Figure 7 shows a further rear view of the driver's side of the exemplary motor vehicle without showing a wall element of a rear wall of the motor vehicle; Figure 8 shows a further rear view of the driver's side of the exemplary motor vehicle with a schematic illustration of a (dis)assembly of a cleaning fluid container of a windshield washer system of the exemplary motor vehicle;Figure 9 shows a vertical sectional view along a longitudinal axis of the exemplary motor vehicle through a height-adjustable roof spoiler of the motor vehicle, wherein the roof spoiler is shown in three different height settings; and Figure 10 shows a perspective rear view of a roof of the exemplary motor vehicle without showing a roof spoiler of the motor vehicle.

[0035] The embodiments shown in the figures correspond at least partially, so that similar or identical parts are provided with the same reference numerals and for their explanation reference is also made to the description of the other embodiments or figures in order to avoid repetition.

[0036] The Figures 1 to 10show different views of different sections of a motor vehicle 10, preferably designed as a truck. It is understood that techniques disclosed herein can also be used in motor vehicles or commercial vehicles of other designs.

[0037] As in particular the Figures 1 and 2 As shown, the motor vehicle 10 has a body 12. The body 12 is preferably designed as a driver's cab body of a driver's cab of the motor vehicle 10. The body 12 can be supported on a vehicle frame, for example, a ladder frame.

[0038] The motor vehicle 10 can have a loading structure 14 for transporting goods. The loading structure 14 is arranged behind the body 12. The loading structure 14 can have a front wall 18 that directly adjoins a rear wall 16 of the body 12. It is also possible for the front wall 18 of the loading structure 14 to be spaced from the rear wall 16 of the body 12. The loading structure 14 can be supported on the vehicle frame. For example, it is also possible for the motor vehicle 10 to have a towed trailer or semi-trailer as an alternative to the loading structure 14, the front wall of which is expediently spaced from the rear wall 16.

[0039] The motor vehicle 10 has at least one door 20. The door 20 provides access to an interior of the motor vehicle 10. The at least one door 20 expediently comprises a driver's door on a driver's side of the motor vehicle 10 and a passenger door on a passenger side of the motor vehicle 10. The door 20 is movably, preferably pivotably, connected to the body 12 for opening the door 20.

[0040] The motor vehicle 10 has at least one outer side panel 22. The outer side panel 22 is designed as an elongated panel. A longitudinal axis of the outer side panel 22 expediently runs parallel to a vertical axis / vertical axis of the motor vehicle 10. The outer side panel 22 is preferably arranged behind the door 20 with respect to the forward direction of travel of the motor vehicle 10. The outer side panel 22 is arranged above an outer fender 24 of a front axle 26 of the motor vehicle 10. In particular, the outer side panel 22 can extend between the outer fender 24 and a roof 28 of the motor vehicle 10. A further outer side panel 22 can be arranged and configured accordingly on the opposite side of the vehicle, for example, the passenger side.

[0041] The outer side panel 22 is movably connected to the body 12, directly or indirectly. Preferably, the outer side panel 22 is pivotably connected to the body 12. The outer side panel 22 can be moved between a closed position, e.g., a pivoted-in position, and an open position, e.g., a pivoted-out position. Figures 1 , 4 to 9 and 10 show the outer side panel 22 in the closed position. Figures 2 to 5 show the outer side panel 22 in the open position. The movement of the outer side panel 22 can conveniently be effected manually. For this purpose, a handle, for example in the form of a recessed grip, can preferably be integrated into an outer side of the outer side panel 22.

[0042] The outer side panel 22 is expediently designed as a so-called side flap. One function of the outer side panel 22 is thus, in particular, to improve the aerodynamics of the motor vehicle 10, in particular by improving the airflow around the motor vehicle 10 at the transition to the loading body 14 (or trailer or semi-trailer). Therefore, in the closed position, the outer side panel 22 can expediently be arranged at an angle obliquely outward to a longitudinal axis of the motor vehicle 10. A rear edge of the outer side panel 22 can thus be aligned, preferably flush, with a front edge of a side wall 30 of the loading body 14. This allows the transition between the narrower driver's cab and the wider loading body 14 to be aerodynamically improved.In embodiments in which, for example, the loading body 14 is spaced apart from the body 12 or a trailer or semi-trailer is towed by the motor vehicle 10, the outer side panel 22 designed as a side flap can additionally or alternatively at least partially, preferably substantially completely, bridge a distance between the rear wall 16 of the (driver's cab) body 12 and the front wall 18 of the loading body 14, the trailer, or the semi-trailer. The outer side panel 22 can therefore protrude beyond the rear wall 16 opposite a forward direction of travel of the motor vehicle 10 or be arranged behind the rear wall 16.

[0043] The Figure 3 , which represents detail A from Figure 2 enlarged, shows the outer side panel 22 in the open position.

[0044] In the illustrated embodiment, the outer side panel 22 is pivotally connected to an outer longitudinal side wall 34 of the body 12 by means of two hinges 32. The outer side panel 22 can be locked in the closed position by means of a locking device 36. The locking device 36 can expediently be unlocked by means of a Bowden cable 38 to release the outer side panel 22. The Bowden cable 38 can preferably be actuated from inside the motor vehicle 10. The outer side panel 22 on the other side of the vehicle (e.g., passenger side) can preferably be unlocked using a different, simpler mechanism.

[0045] The Figure 4 shows a schematic horizontal sectional view along a line BB of Figure 3 through one of the hinges 32. The Figure 4 shows the outer side panel 22 in the open position with a dashed line and in the closed position with a solid line.

[0046] The hinge 32 is attached, on the one hand, to an inner side of the outer side panel 22. On the other hand, the hinge 32 is attached to the longitudinal side wall 34 of the body 12, for example, by means of a retaining bracket 40. Preferably, the outer side panel 22 is detachably attached to the longitudinal side wall 34, for example, by means of at least one screw connection.

[0047] The hinge 32 is arranged on a rear edge of the outer side panel 22. This allows the outer side panel 22 to be pivoted rearward from the closed position, counter to the forward direction of travel of the motor vehicle 10, into the open position. Such a connection can be preferred in that a front edge of the outer side panel 22 is curved at least in sections, while the rear edge of the outer side panel 22 is designed to be straight.

[0048] In the closed position, the outer side panel 22 can additionally be supported and / or centered on the longitudinal side wall 34 by at least one retaining element 42, preferably damped. The retaining element 42 can, for example, be pin-shaped or drop-shaped and engage in a corresponding opening in the outer side panel 22, as shown in Figure 4 The retaining element 42 holds the outer side panel 22 at a front section relative to the forward direction of travel of the motor vehicle 10. It is possible for the retaining element 42 to be rigid or elastic and / or to be rigidly or elastically mounted on the longitudinal side wall 34. Preferably, the retaining elements 42 ensure a secure hold of the outer side panel 22 during operation of the motor vehicle 10 and / or relieve the load on the hinges 32.

[0049] The Figure 5 shows a schematic horizontal sectional view along a line CC of Figure 3by the locking device 36. The Figure 5 shows the outer side panel 22 in the open position with a dashed line and in the closed position with a solid line.

[0050] The locking device 36 can comprise a bolt-shaped locking element 44, for example, and a receptacle or latch 46 for the locking element 44. The locking element 44 is attached to an inner side of the outer side panel 22. The latch 46 is attached to the longitudinal side wall 34. The latch 46 can be actuated by means of the Bowden cable 38 (see also Figure 3 ) can be unlocked.

[0051] It is again pointed out that Figure 3Reference is made. A special feature of the outer side panel 22 is that different functional components can be concealed behind the outer side panel 22 when the outer side panel 22 is in the closed position, and can be accessible from the outside when the outer side panel 22 is open.

[0052] For example, a filler neck 48 can be arranged behind the outer side panel 22. The filler neck 48 can be arranged in a (through) opening of the longitudinal side wall 34. The filler neck 48 can be closed by means of a detachable cover. It is also possible for an adjusting device 50 to be arranged behind the outer side panel 22 and attached to the longitudinal side wall 34. It is also possible for at least one other component 52 to be arranged behind the outer side panel 22 and attached, for example, to the longitudinal side wall 34, as shown schematically in Figure 3is indicated. The component 52 can be designed, for example, as a tool (e.g., towing eye, wiper rod, wheel nut wrench, car jack), a container, or a storage compartment.

[0053] With reference to the filler neck 48 mentioned, reference is made below to the Figures 1 to 3 and 6 to 8 Reference is made.

[0054] The motor vehicle 10 can have a windshield cleaning system 54. The windshield cleaning system 54 can have at least one cleaning nozzle arranged to spray a cleaning fluid onto a windshield of the motor vehicle and / or a lens of a headlight of the motor vehicle 10. The windshield cleaning system 54 further has a pump (not shown), a cleaning fluid tank 56, and the filler neck 48. The filler neck 48 is connected to the cleaning fluid tank via a line 58, for example, a pipe or hose line. The pump can suck a cleaning fluid from the cleaning fluid tank 56 and supply it to the at least one cleaning nozzle of the windshield cleaning system 54.

[0055] Such an arrangement of the filler neck 48 offers the advantage of easy accessibility. Additionally, the cleaning fluid tank 56 can be securely arranged in a previously unused space within the body 12. The cleaning fluid tank 56 is at least partially arranged in a section between an inner fender 60 of the motor vehicle 10 and the outer fender 24 of the motor vehicle. The cleaning fluid tank 56 is arranged behind the door 20 with respect to the forward direction of travel of the motor vehicle 10, preferably inside the rear wall 16 of the body 12.

[0056] This arrangement of the cleaning fluid tank 56 can provide the further advantage of easy assembly and disassembly (for example, in the event of a repair) of the cleaning fluid tank 56. For this purpose, reference is made to the Figure 8which shows how the cleaning fluid tank 56, preferably together with the filler neck 48 and the line 58, can be guided from underneath the motor vehicle 10 to the desired mounting position or removed from it (see double arrow in Figure 8 ). The cleaning fluid tank 56 is thus accessible and mountable from underneath the motor vehicle 10. The arrangement of the cleaning fluid tank 56 also offers the advantage that, in the event of a leak, the cleaning fluid does not flow downward over sensitive components, but can drip directly onto the ground.

[0057] With reference to the aforementioned adjustment device 50, reference is made below to the Figures 1 to 3 and 6 to 9 Reference is made.

[0058] The motor vehicle 10 may have a height-adjustable roof spoiler 62. The Figure 9shows example height settings of the roof spoiler 62. The steepest orientation of the roof spoiler 62 can be used, for example, when installing or removing the roof spoiler on the roof 28. The roof spoiler 62 can be installed and removed (e.g., in the event of damage) without requiring dismantling the loading structure 14, if present. The steepest orientation can be, for example, a vertical or nearly vertical orientation of the roof spoiler 62.

[0059] The roof spoiler 62 is arranged on the roof 28. The roof spoiler 62 can be pivotably mounted on the roof 28 in the region of its front edge. The height of the roof spoiler 62 can be adjusted using the adjustment device 50. By arranging the adjustment device 50 behind the outer side panel 22, good accessibility of the adjustment device 50 can be ensured when the outer side panel 22 is moved into the open position. An adjustment device 50 can be arranged behind a corresponding outer side panel 22 on each of the two longitudinal outer sides of the motor vehicle 10.

[0060] The adjustment device 50 can have a rail 64. The rail 64 is designed as an elongated hole. The rail 64 is vertically aligned. A longitudinal edge of the elongated hole can have several projections 66 arranged one above the other. The projections 66 can enable different possible height adjustments of the roof spoiler 62. The projections 66 can be designed, for example, as prongs, claws, or teeth.

[0061] An elongated connecting element 68 (hidden in Figures 7 and 8 ) can be releasably attached, e.g., by means of a screw connection, to a desired projection 66 of the projections 66. The connecting element 68 connects the adjustment device 50 to the roof spoiler 62. For example, the connecting element 68 can be pivotally attached to an inner side of the roof spoiler 62. The connecting element 68 is preferably designed as a rod, tube, or beam.

[0062] The motor vehicle 10 can also have a trim part 70. The trim part 70 can be arranged between the roof spoiler 62 and the outer side panel 22 and, for example, bridge a gap between a lower edge of the roof spoiler 62 and the roof 28. The gap can be present depending on a height adjustment of the roof spoiler 62. The connecting element 68 can be arranged behind the trim part 70. Thus, the entire mechanism for adjusting the height of the roof spoiler is arranged in a visually appealing manner and protected from the effects of the weather, not visible from the outside. Only when the outer side panel 22 is moved into the open position do the adjustment device 50 and a lower section of the connecting element 68 become visible and accessible.

[0063] The Figures 9 and 10 show the roof 28 of the motor vehicle 10.

[0064] The roof 28 has a roof trench or recess 72. The recess 72 can extend across the entire width of the roof spoiler 62 or the roof 28. The recess 72 serves to partially accommodate the roof spoiler 62 and can also enable its pivoting for height adjustment. A front edge of the roof spoiler 62 dips ever deeper into the recess 72 as the roof spoiler 62 is increasingly tilted. This allows for a uniform and uninterrupted airflow to the roof spoiler 62 during operation.

[0065] The recess 72 can have a curved or bent bottom surface that slopes downwards, at least in sections, toward both longitudinal outer sides of the motor vehicle 10, i.e., is directed diagonally downwards. This prevents water from accumulating on the roof 28. Instead, the water can simply flow away toward the longitudinal outer sides. List of reference symbols
