AI Technical Summary
The existing technologies face challenges in efficiently producing cab variants of commercial vehicles with varying widths and lengths, as they require different components and production methods, making it difficult to create a comprehensive cab portfolio that balances aerodynamics and customer requirements.
A kit system for commercial vehicle cabs that uses a common front wall and first longitudinal section, with a second longitudinal section that can be adjusted in length and width to create different cab versions, allowing for the same front width and aerodynamic design, while using the same rear wall, side flaps, and doors across all versions.
This approach enables the production of cabs with varying widths and lengths using common parts, ensuring a consistent front width and aerodynamic design, particularly benefiting narrow cabs and allowing for the creation of both narrow and wide cab versions with improved aerodynamics.

[0001] Cab kit system and associated manufacturing process
[0002] Description
[0003] The invention relates to a kit system for differently dimensioned cab versions of a commercial vehicle, preferably a truck. The invention further relates to a method for manufacturing a commercial vehicle, preferably a truck, cab.
[0004] Aerodynamics are playing an increasingly important role in the design of truck cabs. Cabs should preferably be relatively narrow at the front. Furthermore, due to different customer requirements, different cab widths are required, so a cab portfolio requires both narrow and wide cabs. For example, narrower designs are preferred for shorter cabs, while wider designs are preferred for longer cabs.
[0005] However, the variance in components and manufacturing methods argues against a large cab portfolio with narrow and wide cabs. Traditionally, various widths are used, starting from the cab front.
[0006] DE 101 18 344 A1 relates to a modular cab series for trucks for creating cab variants of different lengths, with a basic module that is uniformly constructed for all cab variants and with an add-on module that can be attached to it and has different lengths for each cab variant. The basic module has a front wall, two side walls with a door and door frame, a floor, and a roof. It is open to the rear and has a first, closed-ring attachment area at the rear. The add-on module has a rear wall, two side wall sections, a floor section, and a roof section. It is open to the front and has a second, closed-ring attachment area at the front that complements the first attachment area.In the add-on module, the side wall sections, the floor section and the roof section have different length measurements for each cab variant.
[0007] DE 10 2014 008 631 A1 discloses a kit for a commercial vehicle cab with front-wheel drive, comprising at least a narrow version and a wide version, formed with at least the following components that enclose an interior space: a front wall, a rear wall, two flat side walls adjacent to the rear wall, and two curved doors with a first connection to the front wall and a second connection to the side walls. The narrow version has a narrow rear wall, and the wide version has a wider rear wall than the narrow version. Both versions have the same front wall; the two flat side walls are aligned perpendicular to the front wall and rear wall. The two curved doors in the narrow version are aligned at a smaller interior angle to the front wall than in the wide version.
[0008] The invention is based on the object of creating an improved technology for producing different cab versions, which preferably uses a common parts strategy.
[0009] The problem is solved by the features of the independent claims. Advantageous further developments are specified in the dependent claims and the description.
[0010] One aspect of the present disclosure relates to a kit system for differently dimensioned (e.g., wide and / or long) cab versions of a commercial vehicle, preferably a truck. The kit system has a front wall that is the same for the different cab versions. The kit system has a first (e.g., front) cab shell longitudinal section that is the same for the different cab versions, is connectable (e.g., directly), preferably weldable, to the front wall, has two opposing B-pillars, and widens outwards, preferably substantially continuously, from the front wall to the B-pillars. The kit system has a second (e.g., rear) cab shell longitudinal section that has different dimensions depending on the version, preferably long and / or wide, with the first cab shell longitudinal section for extending the cab rearward (e.g.,directly) connectable, preferably weldable, and widens outwards, preferably substantially continuously, from the first cab shell longitudinal section towards a rear end of the second cab shell longitudinal section.
[0011] Advantageously, the various versions and thus floor plans of the cab according to the present disclosure can always originate from the same front width due to the always identical front wall and then taper or widen outwards towards the rear wall of the cab. The extension / widening to the rear extends over both the first longitudinal section of the cab shell and the second longitudinal section of the cab shell. The widening can be the same for all versions up to at least the B-pillar, which has proven particularly advantageous. In this way, with the different cab lengths, different widths of the second longitudinal sections of the cab shell can be created. Because the front wall is narrower than required for the narrowest cab, a kit system is created from which even narrow cabs can arise.In addition, wide cabs can be particularly aerodynamic thanks to their narrow front.
[0012] In one embodiment, at least two, at least three or at least four different lengths and / or different widths of the second cab shell longitudinal section are included.
[0013] In a preferred further development, the different length versions of the second cab shell longitudinal section also have different widths.
[0014] In a further embodiment, the second cab shell longitudinal section is an end section for a rear end of the cab.
[0015] In a further embodiment, the second longitudinal section of the driver's cab shell can be connected to the first longitudinal section of the driver's cab shell (e.g. directly) at the B-pillars or in the area of the B-pillars, and / or the first longitudinal section of the driver's cab shell ends at the two B-pillars.
[0016] In one embodiment, the first cab shell longitudinal section and the second cab shell longitudinal section widen substantially uniformly relative to one another.
[0017] In a further embodiment, the second cab shell longitudinal section widens outwardly (in a different width or width) from the first cab shell longitudinal section to a rear end of the second cab shell longitudinal section, preferably substantially continuously, depending on the version. This advantageously allows for the creation of cabs of different widths.
[0018] In a further embodiment, the second longitudinal section of the cab shell has a rear wall flange for connecting a rear wall to the second longitudinal section of the cab shell. The rear wall flange can preferably have a distance from a central longitudinal axis of the second longitudinal section of the cab shell that is the same for the different cab versions. This advantageously allows the same rear wall to be used for all versions of the cab. In one embodiment, the kit system further comprises a rear wall that is the same for the different cab versions and / or that can be connected (e.g. directly), preferably welded (e.g. to the rear wall flange), to the second longitudinal section of the cab shell.
[0019] In a further embodiment, the second cab shell longitudinal section has at least one side flap flange (or side wing flange) for connecting at least one side flap (or side wing) to the second cab shell longitudinal section. Preferably, the at least one side flap flange can be the same for the different cab versions. This advantageously allows the same side flaps to be used for all versions of the cab.
[0020] In a further embodiment, the kit system further comprises at least one side flap (or side wing) which is the same for the different cab versions and / or which can be connected (e.g. directly), preferably fastened (e.g. on at least one side flap flange), to the second cab shell longitudinal section.
[0021] In one exemplary embodiment, the first longitudinal section of the cab shell and / or the front wall has a door flange for connecting a cab door to the first longitudinal section of the cab shell and / or the front wall. Preferably, the door flange can be the same for the different cab versions. This advantageously allows the same cab door to be used for all versions of the cab.
[0022] In a further embodiment, the kit system further comprises a driver's cab door which is the same for the different driver's cab versions and / or which is movably, preferably pivotably, connectable (e.g. directly) to the first driver's cab shell longitudinal section and / or the front wall (e.g. on the door flange).
[0023] In a further exemplary embodiment, the kit system further comprises a driver's cab floor which is of different lengths depending on the version and / or which can be connected, preferably welded, to the front wall, the first driver's cab shell longitudinal section and the second driver's cab shell longitudinal section (e.g. directly).
[0024] In one embodiment, the kit system further comprises a driver's cab roof that varies in length depending on the version and / or that can be connected (e.g., directly), preferably welded, to the first driver's cab shell longitudinal section and the second driver's cab shell longitudinal section. A further aspect of the present disclosure relates to a method for producing a driver's cab of a commercial vehicle, preferably a truck. The method comprises producing the driver's cab using a kit system as disclosed herein. Advantageously, the same advantages that have already been explained with reference to the kit system can be achieved with the method.
[0025] 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:
[0026] Figure 1 is a perspective view of a commercial vehicle;
[0027] Figure 2 is a perspective view of a cab shell of the commercial vehicle;
[0028] Figure 3 shows a schematic cross-section of components of a kit system for a commercial vehicle cab or cab shell according to an embodiment of the present disclosure; and
[0029] Figures 4 to 8 show schematic cross sections of a commercial vehicle cab or cab shell in different versions, which were manufactured with the kit system according to the present disclosure.
[0030] 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.
[0031] A special feature of the present disclosure is a kit system 58 for producing commercial vehicle cabs 12 in differently dimensioned versions 12A-12E. The kit system 58 is described herein by way of example with reference to Figures 3 et seq. For better understanding, cabs 12 that can be produced using the kit system 58 and commercial vehicles 10 with a corresponding cab 12 are first described below by way of example with reference to Figures 1 and 2. Figure 1 shows a commercial vehicle 10 with a (commercial vehicle) cab 12 having a cab shell 26.
[0032] As shown in Figure 1, the commercial vehicle 10 is preferably designed as a truck. Accordingly, the cab shell 26 can preferably be designed as a truck cab shell. The truck can, for example, be designed as a tractor unit. It is also possible for the truck to be modified such that it has, for example, a (e.g., loading) body.
[0033] The driver's cab 12 or the driver's cab shell 26 can be supported on a vehicle frame 14 of the commercial vehicle 10, for example, with springs and / or dampers. The vehicle frame 14 can be designed, for example, as a ladder frame. It is possible for the driver's cab 12 or the driver's cab shell 26 to be pivoted relative to the vehicle frame 14 by means of a tilting or pivoting device, preferably forward, to provide access to at least one component arranged below the driver's cab 12 or the driver's cab shell 26. This at least one component can, for example, be supported on the vehicle frame 14. This at least one component can, for example, comprise an internal combustion engine, a transmission, an auxiliary unit, a traction battery, and / or an electric drive device, etc.
[0034] The driver's cab 12 can, for example, have a front panel 16, a driver's cab roof 18, at least one driver's cab door 20 and / or at least one side flap or side wing 22, 24.
[0035] The front panel 16 can cover the front of the cab shell 26. The front panel 16 can, for example, be arranged below a windshield of the cab 12.
[0036] The cab roof 18 can cover the cab shell 26 from above. The cab roof 18 can extend substantially over the entire cab shell 26. It is possible for the cab roof 18 to have a, preferably pivotable, roof spoiler.
[0037] The at least one cab door 20 is preferably pivotably connected to the cab shell 26. Preferably, two cab doors 20 are included (only one is visible in Figure 1). For example, the at least one cab door 20 can have a (e.g., driver's) door on a driver's side of the cab 12 and / or a (e.g., passenger's) door on a passenger side of the cab 12.
[0038] The at least one side flap 22, 24 can be arranged at a rear side of the driver's cab 12. The at least one side flap 22, 24 can be attached to the driver's cab shell 26. The at least one side flap 22, 24 can aerodynamically extend the driver's cab 12 rearward. For example, a first side flap 22 can extend a driver's longitudinal outer side of the driver's cab 12 rearward. A second side flap 24 can extend a passenger's longitudinal outer side of the driver's cab 12 rearward.
[0039] Figure 2 shows the cab shell 26 of the cab 12, preferably made of sheet metal.
[0040] The cab shell 26 has a front wall 28, a first cab shell longitudinal section 30, and a second cab shell longitudinal section 44. The cab shell 26 can further have a rear wall 54 and a cab floor 56.
[0041] The front wall 28 can form a front end of the cab shell 26. The front wall 28 can also be referred to as a so-called firewall. The front wall 28 can, for example, have an inverted U-shape. The front wall 28 can be aligned transversely to a central longitudinal axis of the cab shell 26. The front wall 28 can be arranged below a windshield of the cab 12. The front wall 28 can be covered by the front panel 16 (see Figure 1). The front wall 28 is preferably a sheet metal part. The front wall 28 can extend substantially across the entire front width of the cab shell 26.
[0042] The first cab shell longitudinal section 30 is connected to the front wall 28, preferably by means of welded joint(s). Preferably, the first cab shell longitudinal section 30 is connected to opposite ends of the front wall 28. Preferably, the first cab shell longitudinal section 30 can be formed from sheet metal.
[0043] It is possible for the first longitudinal section 30 of the driver's cab shell to have the A-pillars 32, 34. Alternatively, the A-pillars 32, 34 can be formed separately from the first longitudinal section 30 of the driver's cab shell and connected, preferably welded, to the first longitudinal section 30 of the driver's cab shell and / or the front wall 28, for example, when the driver's cab shell 26 is joined. It is also possible for the first longitudinal section 30 of the driver's cab shell to have a cross member 35 arranged between the upper ends of the A-pillars 32, 34. Alternatively, the cross member 35 can be formed separately from the first longitudinal section 30 of the driver's cab shell and connected, preferably welded, to the first longitudinal section 30 of the driver's cab shell, for example, when the driver's cab shell 26 is joined.
[0044] The first cab shell longitudinal section 30 has the B-pillars 36, 38. The first B-pillar 36 can be arranged on a driver's side of the cab shell 26. The second B-pillar 38 can be arranged on a passenger side of the cab shell 26. The B-pillars 36, 38 can be arranged opposite one another. The first cab shell longitudinal section 30 preferably ends at the B-pillars 36, 38.
[0045] Starting from the front wall 28, the first cab shell longitudinal section 30 widens outward toward the B-pillars 36, 38 (transverse to the longitudinal axis of the first cab shell longitudinal section 30). The widening is preferably continuous or essentially uniform over the length of the first cab shell longitudinal section 30. In other words, the first cab shell longitudinal section 30 can taper from the B-pillars 36, 38 toward the front wall 28.
[0046] Specifically, a driver-side outer contour of the first cab shell longitudinal section 30 can lie substantially in a plane that forms an interior angle greater than 90° with a plane in which the front wall 28 lies. A passenger-side outer contour of the first cab shell longitudinal section 30 can lie substantially in a plane that forms an interior angle greater than 90° with a plane in which the front wall 28 lies.
[0047] The first longitudinal section 30 of the cab body shell can have at least one door flange 40, 42. The at least one cab door 20 (see Figure 1) can be attached, preferably pivotably, to the at least one door flange 40, 42. For example, a driver's door 20 (see Figure 1) can be attached to a driver-side door flange 40. A passenger door can be attached to a passenger-side door flange 42. Alternatively or additionally, the at least one door flange 40, 42 can be incorporated into the front wall 28, e.g., arranged at the outer ends of the front wall 28.
[0048] The second cab shell longitudinal section 44 is connected to the first cab shell longitudinal section 30, preferably by means of welded joint(s). Preferably, the second cab shell longitudinal section 44 is connected to the first cab shell longitudinal section 30 at or in the region of the B-pillars 36, 38. Preferably, the second cab shell longitudinal section 44 can be formed from sheet metal.
[0049] The second cab shell longitudinal section 44 can extend the cab shell 26 rearwardly from a rear end of the first cab shell longitudinal section 30. The second cab shell longitudinal section 44 can directly follow the first cab shell longitudinal section 30 with respect to a forward direction of travel of the commercial vehicle 10. The second cab shell longitudinal section 44 can be an end section arranged at a rear end of the cab 12 or the cab shell 26.
[0050] Starting from a rear end of the first cab shell longitudinal section 30, the second cab shell longitudinal section 44 widens outward toward a rear end of the second cab shell longitudinal section 44 (transverse to the longitudinal axis of the second cab shell longitudinal section 44). The widening is preferably continuous or substantially uniform over the length of the second cab shell longitudinal section 44. In other words, the second cab shell longitudinal section 44 can taper from its rear end toward the first cab shell longitudinal section 30.
[0051] For example, the driver's cab 12 or the driver's cab shell 26 can have a tapered shape across the cab shell longitudinal sections 30, 44, with an extension / widening towards the rear or a taper / narrowing towards the front. Preferably, the widening of the driver's cab 12 or the driver's cab shell 26 can be uniform across the first and second cab shell longitudinal sections 30, 44.
[0052] Preferably, a plane in which a driver-side outer contour of the second cab shell longitudinal section 44 essentially lies can enclose an interior angle with a plane in which the front wall 28 lies that is greater than 90°. For example, a driver-side outer contour of the second cab shell longitudinal section 44 and a driver-side outer contour of the first cab shell longitudinal section 30 can essentially lie in the same plane.
[0053] Preferably, a plane in which a passenger-side outer contour of the second cab shell longitudinal section 44 lies can enclose an interior angle with a plane in which the front wall 28 lies that is greater than 90°. For example, a passenger-side outer contour of the second cab shell longitudinal section 44 and a passenger-side outer contour of the first cab shell longitudinal section 30 can lie essentially in the same plane.
[0054] The second cab shell longitudinal section 44 can have at least one rear wall flange 46, 48 for the rear wall 54. The at least one rear wall flange 46, 48 can be arranged at a rear end of the second cab shell longitudinal section 44. The at least one rear wall flange 46, 48 can extend intermittently or continuously over substantially the entire height of the second cab shell longitudinal section 44. The at least one rear wall flange 46, 48 can be aligned in a plane transverse to a central longitudinal axis of the cab 12 or the cab shell 26.
[0055] The rear wall flange 46 and the rear wall flange 48 can be opposite one another. The rear wall flange 46 can be assigned to a driver's side of the second cab shell longitudinal section 44. The rear wall flange 48 can be assigned to a passenger side of the second cab shell longitudinal section 44.
[0056] The second cab shell longitudinal section 44 can have at least one side flap flange 50, 52. The at least one side flap flange 50, 52 can be arranged at a rear end of the second cab shell longitudinal section 44. The at least one side flap flange 50, 52 can be aligned in a plane transverse to a central longitudinal axis of the cab 12 or the cab shell 26.
[0057] The sideflap flange 50 can be assigned to a driver's side of the second cab shell longitudinal section 44. The sideflap 22 (see Figure 1) can be detachably attached to the sideflap flange 50, e.g., fixedly or pivotably. The sideflap flange 52 can be assigned to a passenger side of the second cab shell longitudinal section 44. The sideflap 24 (see Figure 1) can be detachably attached to the sideflap flange 52, e.g., fixedly or pivotably.
[0058] The rear wall 54 can be connected to the rear wall flange 46, 48, preferably by means of welded joint(s). The rear wall 54 can be arranged between the rear wall flange 46 and the rear wall flange 48.
[0059] The cab floor 56 can define the cab shell 26 on the floor side. The cab floor 56 can be connected to the front wall 28, the first cab shell longitudinal section 30, the second cab shell longitudinal section 44, and / or the rear wall 54, preferably by means of welded joint(s).
[0060] Figure 3 shows, purely schematically, components of a kit system 58 according to an exemplary embodiment of the present disclosure. As already mentioned, a special feature of the kit system 58 is that it advantageously enables the construction of differently dimensioned versions 12A-12E of the driver's cab 12 or the driver's cab shell 26, wherein the different versions have some common parts.
[0061] Specifically, the kit system 58 includes the front wall 28 and the first cab shell longitudinal section 30. The front wall 28 is the same or a common part for all different versions of the cab shell 26 or the cab 12. The first cab shell longitudinal section 30 is the same or a common part for all different versions of the cab shell 26 or the cab 12. Consequently, the front wall 28 and the first cab shell longitudinal section 30 can form a basic or base module that is the same across all versions.
[0062] As can be seen from Figure 3, each cab shell 26 derived from / manufactured from the kit system 58 has a widening from front to rear. The widening can be essentially continuous and / or uniform. The widening can be designed as an arrowhead (a longitudinal section of an arrow shape).
[0063] Specifically, the front panel 16 and / or the front wall 28 has, for example, a width B0, which is measured relative to a transverse axis of the driver's cab 12 or the driver's cab shell 26. A rear end of the first driver's cab shell longitudinal section 30 has a width B1, which is measured relative to a transverse axis of the driver's cab 12 or the driver's cab shell 26. The width B1 is greater than the width B0. The first driver's cab shell longitudinal section 30 thus widens from the front wall 28 toward a rear end of the first driver's cab shell longitudinal section 30, e.g., the B-pillars 36, 38. A common length L1 of the front wall 28 and the first driver's cab shell longitudinal section 30 can preferably extend to the B-pillars 36, 38.
[0064] Figures 4 to 8 show, by way of example, a first cab version 12A, a second cab version 12B, a third cab version 12C, a fourth cab version 12D, and a fifth cab version 12E. The cab versions 12A-12E each have the front wall 28, the first cab shell longitudinal section 30, and a respective version of the second cab shell longitudinal section 44A-44E. The second cab shell longitudinal sections 44A-44E have different dimensions depending on the version. In addition, the cab versions 12A-12E can each also have, for example, the front panel 16, the rear wall 54, and / or the side flaps 22, 24.
[0065] As can be seen from Figures 4 to 8, the cab versions 12A-12E have a preferably substantially continuous and / or uniform widening from front to rear. The widening can be designed as a sweep (a longitudinal section of an arrow shape).
[0066] Specifically, the respective widths B2 to B6 at a rear end of the respective second cab shell longitudinal section 44A-44E are greater than the width B0 and greater than the width B1 (see Figure 3). The cab versions 12A-12E thus widen from the front wall 28 to a rear end of the respective second cab shell longitudinal section 44A-44E, which may, for example, end at the rear wall 54.
[0067] The second cab shell longitudinal section versions 44A-44E and thus the cab versions 12A-12E can be of different lengths. For example, the second cab shell longitudinal section 44A and thus the cab 12A can be shorter than the second cab shell longitudinal section 44B and thus the cab 12B (see Figures 4 and 5). The second cab shell longitudinal section 44B and thus the cab 12B can be shorter than the second cab shell longitudinal section 44C and thus the cab 12C (see Figures 5 and 6), etc.
[0068] The cab shell longitudinal sections 44A-44E can, for example, widen differently due to their different lengths L2-L6. For example, a width B2 of the rear end of the second cab shell longitudinal section 44A and thus of the cab 12A can be less wide than a width B3 of the rear end of the second cab shell longitudinal section 44B and thus of the cab 12B (see Figures 4 and 5). A width B3 of the rear end of the second cab shell longitudinal section 44B and thus of the cab 12B can be less wide than a width B4 of the rear end of the second cab shell longitudinal section 44C and thus of the cab 12C (see Figures 5 and 6), etc.
[0069] Figures 4 to 8 thus show several versions 44A-44E of the second cab shell longitudinal section 44, each with different lengths and widths. Preferably, all cab versions 12A-12E have the same rear wall 54. This can preferably be achieved by connecting, preferably weldable, the rear wall 54 to the different versions 44A-44E of the second cab shell longitudinal section 44 via the rear wall flange 46, 48. The rear wall flange 46, 48, in turn, can be designed identically for all versions 44A-44E of the second cab shell longitudinal section 44. In particular, the rear wall flange 46, 48 in all versions 44A-44E of the second cab shell longitudinal section 44 can have an equal distance (y-distance or distance in the transverse direction of the cab) to a central longitudinal axis of the second cab shell longitudinal section 44A-44E.
[0070] Preferably, all or at least some of the cab versions 12A-12E can have the same side flaps 22, 24. This can preferably be made possible by the side flaps 22, 24 being connectable, preferably attachable, to the different versions 44A-44E of the second cab shell longitudinal section 44 via the side flap flanges 50, 52. The side flap flanges 50, 52, in turn, can be designed identically for all versions 44A-44E of the second cab shell longitudinal section 44.
[0071] It is possible for all cab versions 12A-12E to have the same cab doors 20. This can preferably be made possible by the cab doors 20 being movably connected, preferably pivotably, to the first cab shell longitudinal section 30, which is designed as a common part, and / or the front wall 28, which is designed as a common part, via its at least one door flange 40, 42.
[0072] It is also possible that the kit system 58 comprises different length versions of the cab floor 56 and / or the cab roof 18 depending on a version 12A-12E of the cab 12 and thus depending on a version 44A-44E of the second cab shell longitudinal section 44.
[0073] The invention is not limited to the preferred embodiments described above. Rather, a multitude of variants and modifications are possible which also make use of the inventive concept and therefore fall within the scope of protection. In particular, the invention also claims protection for the subject matter and features of the subclaims, independent of the claims referred to. In particular, the individual features of independent claim 1 are each disclosed independently of one another. In addition, the features of the subclaims are also disclosed independently of all features of independent claim 1 and, for example, independently of the features relating to the presence and / or configuration of the front wall, the first longitudinal section of the driver's cab shell, and / or the second longitudinal section of the driver's cab shell of independent claim 1.
