Description

Title of the invention: Vehicle body comprising a crossbar warning of an obstacle on the road by contact with the crossbar.

[0001] The invention relates to a body comprising a crossmember extending downwards and adapted to come into contact with an obstacle extending vertically from the roadway. The invention further relates to an arrangement comprising such a body and a fuel tank. The invention further relates to a vehicle comprising such an arrangement or such a body.

[0002] A vehicle, particularly a motor vehicle, has a ground clearance, that is to say, a height between the lowest point of its body and the road surface, determined in particular according to the type of vehicle. For example, a road-type motor vehicle has a low ground clearance, notably to improve aerodynamics. Conversely, an off-road vehicle has a significant ground clearance due to its potential use on tracks, for example. Regardless of the type of vehicle, it is essential to avoid contact between the vehicle's body and the road surface so as not to damage or deteriorate the body.

[0003] However, in certain vehicle body configurations, the lower part of a fuel tank extends to approximately the same level as the lowest point of the body, for example, with a vertical difference of around 15 mm between the body and the fuel tank. Thus, in the event of a collision between such a tank and a bump or protrusion protruding vertically from the road surface, the tank could be damaged, dented, or even punctured. This would result in a fuel leak and consequently a loss of vehicle range, potentially very rapid. Furthermore, in the case of highly flammable fuel, such as gasoline or a similar product, this creates a risk of fire. Such leakage risks can be increased if the tank is made of plastic.

[0004] Such a situation is not optimal, particularly in terms of safety.

[0005] The objective of the present invention is to provide a box that remedies the disadvantages mentioned above. The invention also allows the vehicle to lean on such an obstacle protruding from the roadway if necessary, without damaging the vehicle, or at least with minimal damage. Summary of the invention

[0006] To achieve this objective, the invention relates to a body for a vehicle, in particular for a motor vehicle, the body comprising a cross member intended to be arranged behind a front wheel assembly of such a vehicle, the cross member extending transversely and projecting downwards so that the cross member comes into contact with an obstacle extending from the roadway to a height greater than the ground clearance of such a vehicle.

[0007] The crossbar can be made of steel.

[0008] The cross member may include a U-shaped or substantially U-shaped section along a vertical and longitudinal plane, the inside of the U being able to form a cavity, the cavity being able to be oriented upwards.

[0009] The crossbar may include a central part and two distal parts, each distal part possibly including a means for fixing the crossbar, in particular a hole.

[0010] The central part of the cross member may include stiffening grooves, in particular obtained by stamping, which may extend along the longitudinal direction.

[0011] The central part of the cross member and / or the two distal parts may include at least one stiffening groove, in particular obtained by stamping, in particular extending transversely.

[0012] The central part of the cross member may include a first extension extending forward and a second extension extending backward, the first extension being able to be of larger dimensions in the transverse and / or longitudinal directions than the second extension.

[0013] The case may include a cradle, the crossbar being able to be fixed to the cradle.

[0014] The case may include a protective shoe, in particular a protective shoe intended to protect an oil pan of an internal combustion engine, the protective skid and the cross member can be fixed to the cradle by means of common fixing means, in particular two screws.

[0015] The invention further relates to an arrangement comprising the body as defined above and a liquid and / or gaseous fuel tank, the ground clearance at the level of the tank being greater than the ground clearance at the level of the crossmember.

[0016] The invention further relates to a vehicle, in particular a motor vehicle, comprising a body as defined above, or an arrangement as defined above. Presentation of the figures

[0025] The direction in which a vehicle, particularly a motor vehicle, moves in a straight line is defined as the longitudinal direction X. By convention, the direction perpendicular to the longitudinal direction, located in a plane parallel to the ground, is called the transverse direction Y. The third direction, perpendicular to the other two, is called the vertical direction Z. Thus, a right-handed coordinate system XYZ is used in which X is the longitudinal direction in the front-to-back direction of the vehicle, i.e., directed towards the rear, Y is the transverse direction directed to the right, and Z is the vertical direction directed upwards. The forward direction corresponds to the direction in which the vehicle usually moves in the longitudinal direction and is opposite to the backward direction.

[0026] As illustrated in [Fig. 1], a vehicle 1, preferably a motor vehicle, comprises a body 2. By "body" is meant a structure, a chassis, for example, comprising a floor extending substantially in a longitudinal and transverse plane. The vehicle 1 preferably comprises at least one front wheel assembly 7 and at least one rear wheel assembly 8. The vehicle 1 preferably comprises a fuel tank 3. For example, the tank 3 is intended to store a liquid fuel and / or a gaseous fuel. The vehicle 1 preferably comprises an arrangement 9. The arrangement 9 comprises the body 2 and the tank 3. Note that the arrangement 9 has a ground clearance G3 at the level of the tank 3. In other words, the lowest point of the arrangement 9 relative to the road surface R is at the level of the tank 3.

[0027] As illustrated in Figures 1, 2 and 3, the body 2 comprises a cross member, a reinforcement, and a warning device 10. In the illustrated embodiment, the cross member 10 is arranged behind the front wheel assembly 7. By "behind the front wheel assembly 7", we mean "behind an axis A7 in the longitudinal direction passing through the axes of the hubs of the front wheels, front wheels not turned", as illustrated in [Fig.3].

[0028] More specifically, the cross member 10 extends transversely or substantially transversely. The cross member 10 further projects downwards from the body 2. As illustrated in [Fig. 1], the cross member 10 extends below the body 2 or below a floor of the body. Advantageously, between the two wheels of the front wheel assembly 7 and between the two wheels of the rear wheel assembly 8 in the transverse direction, the lowest point of the body 2 is located on the cross member 10. In other words, a ground clearance G10 below the cross member 10 is preferably the lowest ground clearance of the vehicle 1.

[0029] Preferably, the ground clearance G10 under the cross member 10 is less than, or at least equal to, the ground clearance G3 under the tank 3.

[0030] Preferably, the cross member 10 is made of steel. Alternatively or in addition, the cross member 10 comprises composite materials, for example comprising fiberglass and / or carbon fiber and / or Kevlar (Registered Trademark).

[0031] The cross member 10 preferably comprises a central portion 12 and two distal portions 13. Each distal portion 13 then comprises a means 135 for attaching the cross member 10. Preferably, each attachment means 135 is a hole. For example, at least one of the two holes is oblong. As illustrated in [Fig. 7], each hole 135 can be oblong; for example, one oblong hole has its long axis extending substantially longitudinally and the other oblong hole has its long axis extending substantially transversely. In this case, attaching the cross member is facilitated by clearances in several directions.

[0032] Preferably, as illustrated in particular in Figures 1 and 6, the cross member 10 comprises a U-shaped or substantially U-shaped section along a vertical and longitudinal plane. The interior of the U then forms a cavity 11, and the cavity 11 is oriented, directed, and open upwards. As illustrated, preferably, the central portion 12 has a curved U-shape, while the distal portions 13 each have a U-shape with two right angles 103, or substantially two right angles, as illustrated in Figures 6 and 7.

[0033] Preferably, the central portion 12 of the cross member 10 comprises a first extension, a forward extension 14. The central portion 12 preferably also comprises a second extension, a rearward extension 15. Preferably, as illustrated in [Fig. 7], each extension 14, 15 has an overall rectangular shape when viewed from above. For example, the first extension 14 has larger dimensions T14, L14, respectively in the transverse and longitudinal directions, than the dimensions T15, L15 of the second extension 15. Preferably, each extension 14, 15 is curved, so as to create the upward-facing U-shaped curve of the central portion 12. Alternatively, the first extension may be the same size, or even have the same dimensions, as the second extension. Alternatively again, the second extension may be larger than the first extension.

[0034] Preferably, the central portion 12 of the cross member 10 comprises at least one stiffening groove or embossed groove 101 extending along the longitudinal direction. For example, the central portion 12 comprises two, three, or even more grooves 101 extending longitudinally. For example, as illustrated in [Fig. 7], the front extension 14 comprises three grooves 101, for example, distributed along the transverse direction such that the central groove is centered on the vertical and longitudinal median plane P illustrated in [Fig. 3]. For example, as illustrated in [Fig. 7], the rear extension 15 comprises three grooves 101, for example, distributed along the transverse direction such that the central groove is centered on the median plane P illustrated in [Fig. 3]. Thus, in the illustrated embodiment, the number of grooves for each extension 14, 15 is identical.For example, extensions 14 and 15 have the same number of grooves, for example two grooves, four grooves, or even more. Alternatively, the front extension and the rear extension have a different number of grooves.

[0035] Preferably, the central portion 12 of the cross member 10 and the two distal portions 13 comprise at least one stiffening groove, or embossed groove, 102. Preferably, the groove(s) 102 extend transversely. Preferably, a space is left between each hole 135 and the transversely extending groove(s) 102, in particular to provide a flat or substantially flat surface for the passage of the fastening means 35 through the holes 135. Thus, reliable support around such holes 135 is possible. Preferably, the fixing means are two screws 35. Each screw 35 then cooperates, passing through each hole 135, a screw head 35 bearing around each hole 135. In addition, it is preferable to provide unstamped, ungrooved material between each hole and a groove 102 so as to maintain the strength properties of the material of the cross member 10.

[0036] Preferably, the grooves 101, 102 are obtained simultaneously with the process for obtaining the cross member 10. Thus, in the case of a process for obtaining the cross member from a steel sheet by stamping, for example, the grooves 101, 102 are obtained by stamping. For example, the thickness of the sheet and consequently of the cross member is between 1.5 mm and 3 mm, preferably 2 mm or 2.5 mm. In the case of grooves 101, 102 extending vertically or substantially vertically upwards, particularly at the extensions 14, 15, The grooves create cavities as illustrated in [Fig.7]. At least one hole 104 is then provided in each cavity.

[0037] For example, the body 2 includes a cradle 20. Such a cradle or support 20 is, for example, intended to help secure an engine 5, possibly an internal combustion engine. In this case, preferably, the cross member 10 is fixed to the cradle 20. In this case, preferably, additional nuts, for example welded, are provided on the cradle 20, for example on an upward-facing side of the cradle. Thus, two screws 35 pass through the holes 135 in the cross member 10 and are screwed into the nuts or threaded holes provided in the cradle. Alternatively, a further screw-nut system may be suitable. Alternatively, threaded rods or studs may extend from the cradle, and nuts are provided to secure the cross member to the cradle. Other fastening methods are possible, for example, including pins.

[0038] Preferably, as illustrated in [Fig. 6], a gap or clearance E14 in the vertical direction is provided between the first extension 14, in particular between a front end of the first extension 14, and the cradle 20. Alternatively, or preferably in addition, a gap or clearance E15 in the vertical direction is provided between the second extension 15, in particular between a rear end of the second extension 15, and the cradle 20. For example, the clearances E14 and E15 are each between 3 mm and 10 mm, preferably between 5 mm and 6 mm.

[0039] As illustrated in [Fig. 5], the housing 2 may include a protective skid plate, a plate 30, for example intended to protect an oil pan 51 of an internal combustion engine 5, if applicable. In this case, preferably, the protective skid plate 30 and the cross member 10 are fixed to the cradle 20 by means of the fastening means 35 seen previously. Thus, the fastening means are common for securing the skid plate 30 and the cross member 10 to the cradle 20. Preferably, as illustrated in [Fig. 5], the skid plate 30 comprises two arms 31 extending longitudinally. Each arm 31 then extends rearward to one end 32 of each arm. Each end 32 is drilled for the passage of the fixing means 35. Preferably, each distal part 13 of the cross member 10 comes into contact with the cradle 20 and each end 32 covers the cross member 10 at the level of the holes 135.Thus, the cross member 10 is sandwiched between the ends 32 of the arms 31 and the cradle 20 via the fixings 35. Alternatively, the arms 31 come into contact with the cradle and the cross member 10 covers the ends 32 so that the cross member and the cradle sandwich the arms 31 of the shoe 30 via the fixings 35.

[0040] Given the configuration of the body 2, including the cross member 10 extending downwards, the presence of an obstacle 4 having a height H4 greater than the ground clearance G10 at the cross member 10 results in contact between obstacle 4 and crossmember 10. In other words, if vehicle 1 moves towards an obstacle 4 whose height exceeds the ground clearance of the crossmember 10, there will be contact, impact, or collision between the crossmember 10 and the obstacle 4. Note that this generally assumes that the obstacle 4 is located between each wheel of each wheel assembly 7, 8, that is, in a zone A under the vehicle with a width E in the transverse direction and a length L in the longitudinal direction, as illustrated in [Fig. 3]. The width E is, for example, between 150 mm and 300 mm. Preferably, the length L is approximately equal to the length of the vehicle. Preferably, the width E is centered or approximately centered with respect to the median plane P.

[0041] As schematically illustrated in [Fig. 1], the term "obstacle" means a protrusion 4, a projection, or a bump extending from the roadway or road R. The obstacle 4 is, for example, a curb, preferably a curb separating two distinct traffic lanes. Such a curb 4 has a height H4 of, for example, between 150 mm and 200 mm. Such a curb is, for example, designed so that a truck, bus, or coach can cross it without damage, for example, for maneuvering purposes. The height H4 of the curb 4 is, for example, too high to be crossed without damaging the vehicle 1. More precisely, the obstacle 4 has a height H4 greater than the ground clearance G3 at the level of the tank 3. Indeed, preferably, the vehicle 1 is a passenger car.For example, obstacle 4 has a height H4, in the vertical direction, of approximately 150 mm, and extends, for example, in the transverse or substantially transverse direction, over approximately 180 mm. Optionally, obstacle 4 has one or more radii or chamfers, for example, at least one radius of approximately 30 mm.

[0042] Thanks to the solution, the presence of an obstacle 4 extending from the roadway to a height H4 greater than the ground clearance G3 of the vehicle is not risky. More specifically, although the vehicle is moving forward so as to subsequently encounter the obstacle 4 in zone A under the vehicle and behind the front axle 7, the presence of the crossmember prevents any significant damage. In other words, although the arrangement 9 or the vehicle 1 includes the liquid and / or gaseous fuel tank 3, the driver of the vehicle is alerted to, hears, and feels the impact and / or friction between the crossmember 10 and the obstacle 4. The driver then instinctively brakes, stops, and / or reverses if the vehicle was moving forward. Thus, the vehicle does not continue its journey until the tank 3 comes into contact with the obstacle 4.We avoid damage to tank 3, possibly a dent, or even a perforation, which could be dangerous.

[0043] Thus, the solution provides that the ground clearance G3 at the level of the tank 3 is greater than the ground clearance G10 at the level of the crossmember 10 so that if the obstacle 4 can pass under the crossbeam 10, so the tank 3 cannot be snagged by this same obstacle. Preferably, a safety margin is provided so that the ground clearance G10 under the crossbeam 10 is significantly less than the ground clearance G3 under the tank 3.

[0044] If vehicle 1 is moving forward towards obstacle 4, with the obstacle 4 positioned between the front wheels in the transverse direction, it is the crossmember 10 that collides with the obstacle and not the tank 3, and / or the body 2, and / or any other equipment protruding below the body 2. Thanks to the clearances E14, E15 illustrated in [Fig. 6], the contact between the obstacle 4 and the crossmember 10, resulting in a deformation along the vertical direction of the crossmember 10 at its central portion 12, is inconsequential. Indeed, if the vertical deformation of the central portion 12 following an impact is less than the clearance(s) E14; E15, this impact has no effect on the subframe 20, which is then not affected. Preferably, these clearances are sufficient to absorb a permanent deformation of the crossmember due to an impact against an obstacle 4 at a vehicle speed of 4 km / h, for example.In other words, the permanent vertical deformation of the crossmember at its central section 12 is at most around 5 mm, which does not cause damage to the subframe, or at least not damage affecting its strength and / or reliability. This permanent deformation may also extend across the width of the obstacle along the vehicle's transverse direction, for example, approximately 180 mm. In such an impact, the permanent deformation of the central section of the crossmember, particularly along the longitudinal direction, is around 10 mm.

[0045] Note that the tank 3 is, for example, held in position relative to the body by a bar, or rod 6 extending, for example, obliquely in a transverse and longitudinal plane, as illustrated in [Fig. 3]. Such a retaining bar 6 is, for example, drilled at both ends so that two screws can pass through it, which then engage with threaded holes or nuts to secure it to the rest of the body. In this case, the ground clearance G3 under the tank extends under this retaining bar 6 and not under the tank 3 itself. Thus, the ground clearance G10 under the crossmember 10 is dimensioned so as not to risk snagging the bar 6 in the event of an impact against the obstacle 4.

[0046] In summary, the solution involves a fuel tank protector preferably positioned well upstream of the tank when moving forward. This protector, of the curved and / or U-shaped crossmember type, allows the integration of a tank 3 with low ground clearance, for example, a tank equipped with a specific pollution control system and / or specific valves. The solution is inexpensive, particularly because it uses simple and widely available production methods such as cutting and stamping in the case of a sheet metal crossmember. Preferably, Pre-drilled threaded holes and / or welded nuts on the cradle allow for the attachment of the crossmember, notably by simultaneously securing it with a protective bracket. This solution is easily industrialized given its minimal impact on an existing production line.

[0047] The U-shaped and / or curved sections of the crossmember, along vertical and longitudinal planes, reinforce it, i.e., improve its impact resistance for a given mass of material. This stiffening allows for relatively small clearances E14, E15 relative to the cradle 20. Furthermore, the slightly curved extensions 14, 15 improve the aerodynamics of the crossmember, for example, significantly in the middle of the vehicle along the transverse direction. Preferably, particularly in the case of a steel crossmember, the holes 104 within the cavities allow for the drainage and evacuation of water and / or moisture present in these cavities, notably to prevent corrosion.

[0048] The solution therefore relates to a fuel tank protector 10 arranged and fixed under the cradle 20, the cradle being intended to support at least partially the engine 5, for example. Preferably, the protective crossmember is in the form of a bar and extends in the transverse direction, for example, along the entire length of the cradle 20. As mentioned, where applicable, the ends 13 of the bar 10 are fixed to the cradle 20 using the same fixing points, preferably two screws 35, as those provided for the housing or skid plate 30 under the engine 5.

[0049] Thus, the protector 10 creates noise and / or vibrations upon contact with the obstacle 4 under the vehicle, which alerts and surprises the driver. The driver is therefore prompted to slow down, brake, stop, or at least be cautious, and possibly reverse. The driver thus becomes aware of the presence of the obstacle and / or the fact that the obstacle 4 is too high for their vehicle. The integration of the crossmember therefore prevents contact between the obstacle 4 and the vehicle's fuel tank 3. This eliminates the risk of damage to the tank, or even a leak, and removes all the risks inherent in a leak of flammable fuel, including fire and / or explosion. Furthermore, it prevents any loss of vehicle range.

[0050] If the vehicle is not stopped and continues moving forward, preferably the crossmember 10 is dimensioned to support up to 1 tonne or even more. Thus, the impact of the vehicle on the obstacle can generate a force lifting the front of the vehicle and the frame onto the obstacle through contact between the crossmember and the obstacle, followed by sliding and / or friction of the crossmember on the obstacle. Note that the curved shape of the first extension 14 of the crossmember 10 also contributes to this situation. Here again, the integration of the crossmember prevents contact between the obstacle 4 and the vehicle's fuel tank 3. Here again, we eliminate the need for Damage to the tank, or even a leak from the tank, is eliminated, along with all the risks inherent in a leak of flammable fuel, including fire and / or explosion. Furthermore, any loss of vehicle range is prevented.

[0051] In the illustrated embodiment, the tank 3 is protected, for example, at a forward speed of 4 km / h. For example, the maximum permanent deformation of the crossmember at a vehicle speed of 4 km / h is approximately 10 mm in the longitudinal direction. Since the fuel tank is located at the rear of the vehicle, the protector 10 is designed to prevent a collision between the obstacle and the tank if the vehicle continues forward.

[0052] Alternatively or in addition, in an embodiment not illustrated, a protective cross member is arranged in front of the A7 axis of the front wheel assembly 7.

[0053] Alternatively or in addition, in an embodiment not shown, a protective crossmember is arranged just in front of the rear wheel assembly 8. In this case, for example, the crossmember is arranged a few centimeters in front of the tank, or less. By "behind, respectively in front, the rear wheel assembly 8", is meant "behind, respectively in front, an axis A8 in the longitudinal direction passing through the axes of the hubs of the rear wheels 8, rear wheels not turned", as illustrated in [Fig. 3].

[0054] Optionally, such a protective crossmember may be provided behind the rear wheel assembly so as to warn in case of reversing over an obstacle in particular.

[0055] As mentioned, the solution prevents the tank from colliding with a bump or protrusion protruding vertically from the road surface. The tank is therefore not damaged, dented, or, most importantly, punctured. A fuel leak, and consequently a potentially very rapid loss of vehicle range, is thus avoided. Furthermore, safety is ensured even in the case of a tank containing highly flammable fuel, such as gasoline or an equivalent and / or a gas. The solution facilitates the integration of tanks made from plastic and / or protruding below the body. In the event of a collision with an obstacle, only the crossmember is impacted. Repair costs are therefore minimal, or even nonexistent.

[0056] As a note, the solution therefore achieves the objective of securing the installation of a tank protruding under a vehicle body by warning the driver and / or passengers of an obstacle too high on the road without resorting to major modifications, and has the advantage of being able to be used to install other fragile and / or risky equipment under a vehicle, for example a battery, elements of a braking circuit or others.
