    In addition, the superstructure is often resiliently suspended at the chassis and a gap is formed between the superstructure and the chassis to allow relative movement between them. A driver's compartment is arranged in the superstructure, usually at a relatively high height above the ground. To facilitate ascent to and descent from the driver's compartment, the vehicle has therefore often been fitted with steps, either on both sides of the superstructure or only on one side.
    A radiator is arranged in front of the engine in the direction of travel of the vehicle. With such a location of the radiator, a cooling air flow is obtained through the radiator, through the engine compartment and out of the engine compartment through an opening in the rear wall of the cab or body while driving as the vehicle is then exposed to speed wind.
    The radiator, the engine and the restriction surfaces make it relatively cramped in the engine compartment, which results in a significant flow resistance and pressure drop for the air that passes through the engine compartment. This causes some of the air flow to leak from the engine compartment, e.g. in the area around the entrance and through the gap between the superstructure and the chassis and affects the air flow around the cab or body corners by e.g. push this out of its position near the cab or body side. This results in that the air resistance and thus also the fuel consumption increases and that the side is only flushed by a limited air flow or that the air flow passes the side without a cleaning effect.
    SUMMARY OF THE INVENTION An object of the present invention is to improve the aerodynamic properties of a commercial vehicle by providing means for redirecting an air stream which reduces the air resistance of the vehicle and thus also fuel consumption.
    Another object is to provide means for redirecting an air stream which reduces the degree of soiling of a superstructure side of a vehicle. These and other objects are achieved by the features set forth in the appended claims.
    By utilizing the redirecting means according to the invention, the disordered leakage flow from the engine compartment out to the cab or body side is reduced, which means that the air flow, ie. the wind, which is controlled around the corner and along the side is not pushed out but instead 10 15 20 25 30 3 is allowed to pass close to the side which reduces the vehicle's air resistance and thus also its fuel consumption and effectively prevents splashes and other dirt particles from the wheels when the cab and the side of the vehicle door.
    In an advantageous embodiment, the redirecting means is arranged at a transition area between the corner portion of the vehicle and the side portion. This is a favorable location because the road from the air inlet openings from the front part to the transition area means the shortest distance and the least resistance to the leakage flow.
    In a further advantageous embodiment, the redirecting means is arranged on one step. This facilitates the assembly of the vehicle because the redirecting means can be pre-assembled on the step which is then mounted on the vehicle as a unit.
    The redirecting means can advantageously be arranged on a vehicle whose cab is resiliently suspended from a chassis. The redirecting means then covers at least a part of the clearance formed between the cab and the chassis to enable the cab to spring relative to the chassis and prevent leakage flows through the clearance.
    In addition, the redirecting means can advantageously be arranged on a vehicle with a vortex generator adapted to convert an air flow generated by the wind wind into a vortex flow which follows the side portion of the vehicle adjacent to the corner portion.
    The vortex generator reduces the degree of soiling of the cab or body side without increasing the vehicle's air resistance, but the vortex flow cleaning effect increases while the vehicle's air resistance decreases by allowing the vortex flow due to the redirector to pass close to the side and not be pushed out from the side by a leakage flow from the engine.
    Other features and advantages of the invention will be apparent from the claims, the description of exemplary embodiments and the accompanying figures.

    DETAILED DESCRIPTION OF EMBODIMENT FORVIVES OF THE INVENTION Figure 1 shows the front part of a vehicle 1, in this case a truck in the form of a tractor intended to tow a semi-trailer (not shown). The vehicle 1 comprises a superstructure in the form of a cab 2 with a front surface 6 directed forwards in the direction of travel of the vehicle 1. The cab 2 is resiliently arranged in a manner not further shown on a chassis 3 in the form of a chassis 3.
    On each side of the front surface 6 at least one front corner portion 4 is arranged, of which only one corner portion 4 is shown in Fig. 1. The respective front corner portion 4 is formed at the cab 2 by a curved corner panel 5 which is arranged between an upper front cover 7 included in the front surface 6. and a side portion 8 extending from the corner portion 4 backwards in the direction of travel of the vehicle 1 and comprising a vehicle door 9. At the chassis 3, the corner portion 4 is formed by a curved portion 10 of a bumper 11. The upper part of the curved portion 10 part extends between a lower front door 12 included in the front surface of the vehicle 6 and an entrance 16 with stair elements in the form of footsteps 13 arranged in a step well 14 below the door 9. The lower part of the curved portion 10 extends between a front part 15 of the bumper 11 and entered 16.
    During travel, a first air flow f1 folded by the wind wind is controlled around the corner portion 4 and along the side portion 8 in order to reduce the air resistance and ensure that the side portion 8 is continuously flushed by an air gap f1 which prevents it from being contaminated from below by splashes and dirt particles.
    At the respective corner portion 4 between the cab 2 and the chassis 3 there is an outwardly open recess 19 which extends around and along substantially the entire corner portion 4 and continues along the lower edge of the door 9. The recess 19 is formed as a consequence of the fact that the cab 2, which is resiliently suspended with overlap on the outside of the chassis 3, needs to have a vertical clearance for its suspension movements with respect to the chassis 3. The recess 19 itself constitutes and thus leaves the necessary clearance which makes it possible for the cab 2 to spring relative to the chassis 3 without the cab 2 and the chassis 3 colliding with each other.
    In an alternative embodiment, a schematically shown air deflector 20 is arranged in the recess 19. The air deflector 20 is of the type called vortex generator and comprises an aerodynamically acting surface such as e.g. a wing or the like which creates a second air flow, an air vortex v which is capable of adhering or being pulled to the side portion 8, in order to further reduce the air resistance and improve the cleaning effect. The air outlet 31 (Fig. 7) of the air deflector 20 is advantageously located in the longitudinal direction of the vehicle at or substantially at a corner transition area 48 between the front corner portion 4 and the side portion 8.
    The air deflector 20 includes a downwardly open elongate air conducting channel. Figure 2 shows a cross section of the channel 21 in a position near the front surface 6. The channel 21 is connected to the front corner portion 4 of the cab 2 and extends curved around substantially the entire corner portion 4 from the front surface 6 of the cab 2 to its side portion 8. The channel 21 comprises, as best seen in Figure 3 showing a cross section of the channel 21 in a position AA (Figure 2), two downwardly directed substantially vertical opposite sides 22, 23 with each free lower end edge 24, 25 and an upper arcuate portion 26 which connects the sides 22, 23.
    The first side 22 faces the outside of the vehicle 1 and the second side 23 faces an engine 32 arranged in the vehicle 1. The sides 22, 23 extend towards the chassis 3 down into the outwardly open recess 19 but leave a clearance 18 which makes it possible for the cab 2 to spring relative to the chassis 3 without the cab 2 and the chassis 3 colliding with each other.
    Figure 4 shows an alternative embodiment of the air deflector 20. In this embodiment the second side 23 of the downwardly open duct 21 is connected to the chassis 3 and thus has no free lower end edge but instead a free upper end edge 27. The other side 23 extends from the chassis 3 towards the cab 2 but leaves a clearance 18, which has the shape of an opening in the arcuate portion 26 and which enables the cab 2 to spring relative to the chassis 3 without the cab 2 and the chassis 3 colliding with each other.
    During travel, as shown in Fig. 1, an air flow f2 forged by the speed wind is controlled into the recess 19 and further through the air deflector 20 which converts the air flow f2 into a second air flow, a vortex flow v which after moving the air deflector 20 is moved along the side portion 8 .
    More specifically, in the example shown, the vortex flow is moved substantially along the lower part of the vehicle door 9 and is then guided upwards along an inclined plane of a mudguard 29 mounted over a wheel 30. The vortex v reduces the air resistance and prevents splashes and other dirt particles from the wheel. 30 reaches the cab 2 and the side of the vehicle door 9.
    A problem with known corner portions 4 and air deflector 20 is that the first air flow f1 and / or the second air flow i.e. the vortex flow v can be affected and disturbed by other air flows that may occur in vehicles 1 whose engine is located in the chassis 3 under the cab 2.
    To illustrate this, Figure 5 shows a side view with broken away parts of the vehicle 1 shown in Figure 1. An engine 32, in this example a diesel engine, is arranged in a space, an engine compartment 33, under the floor 34 of the cab 2 behind the front surface. 6. The floor 34 then constitutes an upper limit on the size of the engine compartment 33. The motor 32 and is mounted in the chassis of a vehicle frame 36 comprising two elongate parallel frame side beams 37, only one of which is shown in the figure, which are connected to each other by a number of crossbeams (not shown) and are arranged to via a drive line (not shown) transmits drive torque to drive wheels (not shown). A noise cap 38 is arranged between the frame side beams 37 in a position below the motor 32 and constitutes a lower limitation of the size of the engine compartment 33.
    A number of spring means 40 in the form of gas springs are arranged between the cab 2 and the vehicle frame 36. One end of each gas spring 40 abuts the vehicle frame 36, either directly or via an intermediate bracket 41, while its other end supports the cab 2. The spring means 40 carry the cab 2 and balances it in a resilient position during operation of the vehicle 1.
    In the upper and lower front cover (7, 12) of the front part 6, inlet openings 42 are formed intended to supply the air gap f generated by the wind wind to a cooling system 43.
    The cooling system 43 comprises a circulating coolant which is circulated in a pipe system (not shown). The circulating coolant is arranged to cool the engine 32 and emits its heat in a cooler 44 located near the front portion 6. The circulating coolant is cooled in the cooler 44 by the air flow f which after passing the inlet openings 42 flows further through passages in the cooler 44 and further. through the engine compartment 33 which is tunnel shaped. After passing the engine compartment 33, the air flow f the engine compartment 33 leaves through an opening 45 at the rear edge of the cab 2.
    The path of the air flow through the engine compartment 33 is symbolically shown by means of arrows fa, fb.
    A fan 46 may be provided at the radiator 44 to increase the air flow f towards the radiator 44.
    The fan 46 may or may not be active, but in both cases the air flow f passes through the engine compartment 33 when driving the vehicle.
    The vehicle's drive unit, ie. the radiator 44, the engine 32 and a gearbox 35 but also, the cab floor 34, the noise cap 38 and other components around the engine 32 cause it to be relatively cramped in the engine compartment 33 resulting in a substantial flow resistance and pressure drop for the air flow f passing through the engine compartment 33. causes an air flow f3 which forms at least a part of the air flow f to leak from the engine compartment 33, e.g. in the area around the entrance 16 shown in Figure 1 and / or through the recess 19 and the clearances 18 between the cab 2 and the chassis 3, since the path to the entrance 16, the recess 10 and the clearances 18 means the shortest distance and least resistance to the air flow f3.
    The leaking air flow f3 can weaken and change direction of the first air flow f1 and / or the second air flow, ie. the vortex flow v which results in the cleaning effect of the air flows f1, v decreasing or even failing and that the air resistance and thus also the fuel consumption increases.
    Figure 6 shows a summary schematic picture of the different air flows. During travel, the first air flow f1 folded by the wind is controlled around the corner portion 4 and along the side portion 8. In an alternative embodiment, the air flow f2 folded by the wind is guided into the recess 19 and further through the air deflector 20 which converts the air flow f2 to a second air flow. the air flow v. The air flow also passes the inlet openings 42 in the front surface 6 and flows further through the engine compartment 33 past the engine 32 and out through the opening 45 at the rear edge of the cab. The leaking air flow f3 can collide with and thereby weaken and change direction of the first air flow f1 and / or the second air flow, ie. the vortex flow v which when this happens results in the air flow f1, v cleaning effect decreasing or even failing and that the air resistance and thus also the fuel consumption increases.
    According to the invention, as shown in Fig. 7, at least one redirecting means 50 is adapted to redirect the air flow f3 which forms at least a part of the air flow f in a direction f5 where it does not affect and disturb the first air flow f1 and / or the second air flow i.e. the vortex flow v flowing along the side portion 8. Such a direction may be rearward in the direction of travel of the vehicle 1 towards the opening 45 at the rear edge of the cab. Although only one front corner portion 4 is shown in FIG. 7, there is at least one redirecting member 50 at the second, not shown, front corner portion 4 of the vehicle 1.
    The redirector 50 can be made of any material that has the right properties in terms of material strength, resistance to the environment in which it is located, etc. The redirector 50 can e.g. be made of a plastic material or of a metal alloy with suitable properties, preferably in the form of a metal sheet.
    The redirecting means 50 is arranged between the drive assembly 44, 32, 35 (Fig. 5) and the side of the side portion 8 facing the engine compartment 33 (Fig. 7) and may be arranged at different positions in the longitudinal direction. By longitudinal direction is meant a direction which is substantially parallel to a direction from the inlet openings 42 where incoming air f flows in, to the opening 45 at the rear edge of the cab 2 where the air escapes the engine compartment 33.
    The redirecting means 50 is advantageously arranged in the longitudinal direction at or substantially at a corner transition area 48 between the front corner portion 4 and the side portion 8 and in the vertical direction in or substantially in the area at the clearance 19,18 between the cab 2 and the chassis 3.
    The redirecting means 50 is advantageously arranged at the chassis 3, but it is also possible to arrange it at the cab 2 without the inventive idea being lost. In such an embodiment, the redirecting means 50 is arranged in a manner not shown in a manner shown at the cab 2 and extends substantially in the vertical direction downwards into or substantially into the area at the clearance 18 in the recess 19 (Fig. 1) between the cab 2 and the chassis 3 on a in such a way that it redirects the air flow f3 and with retained function does not risk colliding with the corner portion 4 or other parts of the cab 2 during large vertical suspension movements of the cab 2. The redirecting means 50 is moreover advantageously arranged on an interior surface of the vehicle but it is possible to arrange it at an external surface without the inventive idea being lost.
    In the embodiment schematically shown in Figure 7, the redirecting means 50 is mounted at the step 16 with a bracket (not shown). Fig. 8 shows that the step 16 is in turn mounted to a supporting structure 51 which is attached to the chassis 3, or more precisely to the frame side beam 37. The step 16 has two opposite substantially vertical sides 52,53, a front side 54 and a back side 55 at which the supporting structure 51 is arranged and which connects the two vertical sides 52,53 to each other to form the step well 14. On the front side 54 the footsteps 13 are arranged but these are not shown in the figure. The redirecting means 50 is advantageously fixedly connected to the front vertical side 52 facing the corner portion 4 with suitable fastening means 56, but it is of course possible to connect the redirecting means 50 to the vertical side 53 facing the rear end portion of the vehicle or in another position at the entrance 16 without Is lost.
    Figure 1 shows that the outwardly open recess 19 extends around and along substantially the entire corner portion 4 and continues along the lower edge of the door 9 to enable the cab 2 to spring relative to the chassis 3 without the cab 2 and the chassis 3 collide with each other. The outwardly open recess 19 thus extends between the door 9 and the step 16. In Fig. 8 it is shown that the redirecting means 50 is connected to the front vertical side 52 in a position where it projects a distance X from the upper edge 17 of the step 16 towards the outward open the recess 19 (fig.1) to be able to redirect the third air flow f3 (fig.7). The redirecting means 50 extends substantially in the vertical direction upwards into or substantially into the area at the clearance 18 in the recess 19 (Fig. 1) between the cab 2 and the chassis 3 in such a way that with retained function it does not risk colliding with the corner portion 4 or other parts of the cab 2 during large vertical suspension movements of the cab 2.
    The redirecting means 50 in Figure 7 can be designed in a variety of ways without the inventive idea being lost, but the various embodiments have in common that they comprise a guide surface 58 which is adapted to receive and redirect at least a part of the third air flow f3. In an advantageous embodiment, the guide surface 58 extends substantially in a vertical plane, but it can be arranged so that at least a part of it is inclined relative to the vertical plane to redirect the flow f3 in the desired direction if this is more advantageous in the vehicle in question.
    The guide surface 58 has a main extension from the corner portion 4 in a direction 47 which forms an angle oi with an imaginary line 59 which is substantially perpendicular to the extension of the front surface 6 and which extends from the longitudinal direction of the vehicle 1 through the entrance 16.
    The angle oi may be between 0 ° and 90 ° but preferably between 20 ° and 70 ° or more advantageously between 30 ° and 50 °.
    The guide surface 58 may be substantially flat or comprise e.g. projections, ridges or raised edges to redirect the air flow f3. The guide surface 58 may also include various wavy or curved shapes. An example of such a curved shape is shown in Fig. 7 where the guide surface 58 is formed with a substantially planar section 60 and adjacent curved sections 61. In an alternative embodiment, the guide surface 58 may comprise a number of substantially planar sections 60 with adjacent curved sections 61.
    In one embodiment, the guide surface 58 may be formed on a component in the engine compartment in connection with e.g. the corner portion 4, the component itself constituting the redirecting means 50. The guide surface 58 may also be formed on containers for washer fluid or the like or on storage compartments or the like which are arranged in connection with the corner portion 4, the entrance 16 or these adjacent surfaces.
    Fig. 7 shows a second redirecting means 62 having the shape of a plate or the like extending in a horizontal plane between the vertical sides 52,53 at the upper edge 17 of the step 16 (Fig. 8). The redirecting means 62 comprises a guide surface for redirecting air currents f3 and preventing them from flowing down into the entrance 16 and further out past the side portion 8 and influencing the first air flow f1 and / or the second air flow, i.e. the vortex flow v. The second redirecting means 62 may be arranged at the cab 2 or at the chassis 3 but preferably at the entrance 16 which forms part of the chassis structure.
    The invention is not limited to the described embodiments, but a number of possibilities for modifications thereof should be obvious to the person skilled in the art without departing from the basic idea of the invention as defined in the claims.
