Description

Technical Field

[0001] The invention relates to a kit system for cab versions of different sizes for a cab of a commercial vehicle, preferably a truck. The invention also relates to a method for manufacturing a cab of a vehicle, preferably a truck. Background Art

[0002] Aerodynamics plays an increasingly important role in the design of truck cabs. Preferably, the front of the cab should be relatively narrow. In addition, different customer requirements require different cab widths, so the cab portfolio (Fahrerhausportfolio) requires narrow and wide cabs. For example, short cabs tend to have a narrow design, while long cabs tend to have a wide design.

[0003] However, differences in components and manufacturing processes have prevented the adoption of a large cab portfolio that includes narrow and wide cabs. Traditionally, different widths have been used starting at the front of the cab.

[0004] DE 101 18 344 A1 relates to a modularly constructed series of truck cabs for forming cab variants of different length dimensions, with a basic module of uniform design for all cab variants and an additional module of different length dimensions for each cab variant and attachable to the basic module. The basic module has a front wall, two side walls with doors and door frames, a floor and a roof, is open at the rear and has a first annularly closed flange area at the rear. The additional module has a rear wall, two side wall sections, a floor section and a roof section, is open at the front and has a second annularly closed flange area complementary to the first flange area at the front. In the additional module, the side wall sections, the floor section and the roof section have different length measurements for each cab variant.

[0005] DE 10 2014 008 631 A1 discloses a kit for a cab of a commercial vehicle with front-wheel steering, which comprises at least a narrow version and a wide version and is formed by at least the following components enclosing an interior space: a front wall, a rear wall, two flat side walls adjacent to the rear wall, and two curved doors, the curved doors having a first connection portion for the front wall and a second connection portion for the side walls. The rear wall of the narrow version is narrower, while the rear wall of the wide version is wider than the rear wall of the narrow version. Both versions have the same front wall, and the two flat side walls are vertically aligned with the front wall and the rear wall. The inner angles of the two curved doors in the narrow version relative to the front wall are smaller than those in the wide version. Summary of the invention

[0006] The object of the present invention is to propose an improved technology for manufacturing different cab versions, preferably using a common parts strategy.

[0007] This object is achieved by the features of the independent claim. Advantageous developments are specified in the dependent claims and in the description.

[0008] One aspect of the present disclosure relates to a kit system for cab versions of different sizes (e.g., varying width and / or length) of a cab of a commercial vehicle (preferably a truck). The kit system has a front wall, which is the same for the different cab versions. The kit system has a first (e.g., front) cab frame longitudinal section, which is the same for the different cab versions, can be (e.g., directly) connected (preferably, welded) to the front wall, has two opposite B-pillars, and widens (preferably, substantially continuously) from the front wall toward the B-pillars. The kit system has a second (e.g., rear) cab frame longitudinal section, which has different sizes (preferably, length and / or width) depending on the version, can be (e.g., directly) connected (preferably, welded) to the first cab frame longitudinal section to extend the cab rearwards, and widens outwards (preferably, substantially continuously) from the first cab frame longitudinal section toward the rear end of the second cab frame longitudinal section.

[0009] Advantageously, due to the always identical front wall, the different versions of the cab according to the invention and therefore the profile can always originate from the same front width and then extend or widen outwards in the direction of the rear wall of the cab. The widening / widening towards the rear is present on the first cab frame longitudinal section and on the second cab frame longitudinal section. The widening is identical for all versions at least until the B-pillar, which has proven to be particularly advantageous. In this way, by using second cab frame longitudinal sections of different lengths, cab versions of different widths can be created depending on the different cab lengths. Since the front wall is narrower than would be necessary for the narrowest cab, a kit system is created with which even narrow cabs can be manufactured. In addition, due to the narrow front section, the wide cab also has particularly good aerodynamic properties.

[0010] In an embodiment, at least two, at least three or at least four versions of different length and / or different width of the second cab frame longitudinal section are comprised.

[0011] In a preferred development, the different length versions of the second cab frame longitudinal section also have different widths.

[0012] In another embodiment, the second cab frame longitudinal portion is an end portion of the rear end of the cab.

[0013] In a further embodiment, the second cab frame longitudinal section can be connected to the first cab frame longitudinal section at or in the region of the B-pillars (eg directly) and / or the first cab frame longitudinal section ends at two B-pillars.

[0014] In an embodiment, the first cab frame longitudinal section and the second cab frame longitudinal section are substantially uniformly widened relative to each other.

[0015] In another embodiment, the second cab frame longitudinal section widens outwards (widely or widely) from the first cab frame longitudinal section towards the rear end of the second cab frame longitudinal section to different degrees depending on the version, preferably substantially continuously. This can advantageously enable the creation of cabs of different widths.

[0016] In another embodiment, the second cab frame longitudinal section has a rear wall flange for connecting the rear wall to the second cab frame longitudinal section. Preferably, the distance between the rear wall flange and the central longitudinal axis of the second cab frame longitudinal section may be the same for different cab versions. This may advantageously enable all cab versions to use the same rear wall.

[0017] In an embodiment, the kit system further comprises a rear wall which is identical for the different cab versions and / or which can be connected (e.g. directly) to the second cab frame longitudinal section, preferably by welding, e.g. to the rear wall flange.

[0018] In another embodiment, the second cab frame longitudinal section has at least one side dam flange (or wing flange) for connecting at least one side dam (or wing) to the second cab frame longitudinal section. Preferably, the at least one side dam flange may be identical for different cab versions. This may advantageously enable all cab versions to use the same side dam.

[0019] In another embodiment, the kit system further comprises at least one side dam (or side wing) which is identical for the different cab versions and / or which can be connected (e.g. directly) to the second cab frame longitudinal section, preferably fixed to the second cab frame longitudinal section, e.g. fixed to at least one side dam flange.

[0020] In one embodiment, the first cab frame longitudinal section and / or the front wall has a door flange for connecting the cab door to the first cab frame longitudinal section and / or the front wall. Preferably, the door flange can be the same for different cab versions. This can advantageously allow all cab versions to use the same cab door.

[0021] In another embodiment, the kit system further comprises a cab door which is identical for different cab versions and / or can be movably, preferably pivotably connected (e.g. directly connected) to the first cab frame longitudinal section and / or the front wall, e.g. to a door flange.

[0022] In another embodiment, the kit system further comprises a cab floor which has different lengths depending on the version and / or can be connected (preferably welded) (eg directly) to the front wall, the first cab frame longitudinal section and the second cab frame longitudinal section.

[0023] In an embodiment, the kit system further comprises a cab roof which has different lengths depending on the version and / or can be connected (preferably welded) (eg directly) to the first cab frame longitudinal section and the second cab frame longitudinal section.

[0024] Another aspect of the invention relates to a method for manufacturing a cab for a commercial vehicle, preferably a truck. The method comprises manufacturing the cab using the kit system disclosed herein. Advantageously, the method can achieve the same advantages as explained with reference to the kit system.

[0030] Since the embodiments shown in the figures correspond at least partially, similar or identical components are provided with the same reference signs, and for their explanation reference is also made to the description of the other embodiments or figures in order to avoid repetitions.

[0031] The present invention is characterized in that a kit system 58 is provided for producing commercial vehicle cabs 12 in different size versions 12A-12E. Figure 3 The following figures illustrate the kit system 58 by way of example. For a better understanding, refer to Figure 1 and Figure 2 A cab 12 that can be manufactured using the kit system 58 and a commercial vehicle 10 having a corresponding cab 12 are described by way of example.

[0032] Figure 1 A commercial vehicle 10 is shown having a (commercial vehicle) driver's cab 12 having a driver's cab frame 26 .

[0033] like Figure 1 As shown, the commercial vehicle 10 is preferably designed as a truck (Lastkraftwagen). Therefore, the cab frame 26 can preferably be designed as a truck cab frame. For example, the truck can be designed as a tractor. The truck can also be modified, for example, to have a (for example, loading) compartment.

[0034] The cab 12 or the cab frame 26 can be supported on the frame 14 of the commercial vehicle 10, for example, by means of springs and / or shock absorbers. The frame 14 can be designed, for example, as a ladder frame. The cab 12 or the cab frame 26 can be pivoted relative to the frame 14, preferably forwardly, by means of a tilting or pivoting device, so that at least one component arranged below the cab 12 or the cab frame 26 is accessible. The at least one component can, for example, be supported on the frame 14. The at least one component can, for example, include an internal combustion engine, a transmission, an auxiliary device, a traction battery and / or an electric drive, etc.

[0035] The cab 12 may, for example, have a front panel 16 , a cab roof 18 , at least one cab door 20 and / or at least one side panel or wing 22 , 24 .

[0036] The front panel 16 may cover the front portion of the cab frame 26. The front panel 16 may be disposed below a windshield of the cab 12, for example.

[0037] The cab roof 18 can cover the cab frame 26 from above. The cab roof 18 can extend substantially over the entire cab frame 26. The cab roof 18 can have a preferably pivotable roof spoiler.

[0038] The at least one cab door 20 is preferably pivotally connected to the cab frame 26. Preferably, two cab doors 20 ( Figure 1 For example, the at least one cab door 20 may include a door on the driver's side of the cab 12 (eg, a driver's door) and / or a door on the passenger's side of the cab 12 (eg, a passenger's door).

[0039] The at least one side guard 22, 24 may be disposed at the rear side of the cab 12. The at least one side guard 22, 24 may be attached to a cab frame 26. The at least one side guard 22, 24 may extend the cab 12 rearward in an aerodynamic manner. For example, the first side guard 22 may extend the longitudinal outer side of the cab 12 rearwardly. The second side guard 24 may extend the longitudinal outer side of the cab 12 rearwardly.

[0040] Figure 2 A cab frame 26 of the cab 12 is shown, which is preferably made of sheet metal.

[0041] The cab frame 26 has a front wall 28, a first cab frame longitudinal portion 30, and a second cab frame longitudinal portion 44. The cab frame 26 may also include a rear wall 54 and a cab floor 56.

[0042] The front wall 28 may form the front end of the cab frame 26. The front wall 28 may also be referred to as a so-called engine baffle (Firewall). The front wall 28 may have, for example, an inverted U-shape. The front wall 28 may be aligned transversely with respect to the central longitudinal axis of the cab frame 26. The front wall 28 may be arranged below the windshield of the cab 12. The front wall 28 may be covered by the front panel 16 (see Figure 1 ). Preferably, the front wall 28 is a sheet metal component. The front wall 28 can extend substantially over the entire front width of the cab frame 26.

[0043] The first cab frame longitudinal portion 30 is connected to the front wall 28, preferably using a welded connection. Preferably, the first cab frame longitudinal portion 30 is connected to opposite ends of the front wall 28. Preferably, the first cab frame longitudinal portion 30 may be formed from sheet metal.

[0044] The first cab frame longitudinal portion 30 may have A-pillars 32, 34. Alternatively, the A-pillars 32, 34 may be formed separately from the first cab frame longitudinal portion 30, for example, and may be connected (preferably welded) to the first cab frame longitudinal portion 30 and / or the front wall 28, for example, when the cab frame 26 is joined.

[0045] The first cab frame longitudinal portion 30 may further include a cross beam 35 disposed between the upper ends of the A-pillars 32, 34. Alternatively, the cross beam 35 may be formed, for example, separately from the first cab frame longitudinal portion 30 and may be connected (preferably welded) to the first cab frame longitudinal portion 30, for example, when the cab frame 26 is joined.

[0046] The first cab frame longitudinal section 30 has B-pillars 36, 38. The first B-pillar 36 can be arranged on the driver's side of the cab frame 26. The second B-pillar 38 can be arranged on the passenger side of the cab frame 26. The B-pillars 36, 38 can be arranged opposite to each other. Preferably, the first cab frame longitudinal section 30 ends at the B-pillars 36, 38.

[0047] Starting from the front wall 28, the first cab frame longitudinal section 30 widens outwardly toward the B-pillars 36, 38 (transversely with respect to the longitudinal axis of the first cab frame longitudinal section 30). This widening is preferably continuous or substantially uniform over the length of the first cab frame longitudinal section 30. In other words, the first cab frame longitudinal section 30 may gradually narrow from the B-pillars 36, 38 toward the front wall 28.

[0048] Specifically, the plane where the driver's side outer contour of the first cab frame longitudinal portion 30 is located can substantially form an inner angle greater than 90° with the plane where the front wall 28 is located. The plane where the passenger's side outer contour of the first cab frame longitudinal portion 30 is located can substantially form an inner angle greater than 90° with the plane where the front wall 28 is located.

[0049] The first cab frame longitudinal section 30 may have at least one door flange 40, 42. The at least one cab door 20 (see Figure 1 ) can preferably be attached to the at least one door flange 40, 42 in a pivotable manner. For example, the driver's door 20 (see Figure 1 ) may be attached to the driver's side door flange 40. The passenger door may be connected to the passenger's side door flange 42. Alternatively or additionally, the at least one door flange 40, 42 may be included in the front wall 28, for example arranged at an outer end of the front wall 28.

[0050] The second cab frame longitudinal section 44 is connected to the first cab frame longitudinal section 30, preferably using a welded connection. Preferably, the second cab frame longitudinal section 44 is connected to the first cab frame longitudinal section 30 at the B-pillars 36, 38 or in the region of the B-pillars 36, 38. Preferably, the second cab frame longitudinal section 44 can be formed from sheet metal.

[0051] The second cab frame longitudinal portion 44 may extend the cab frame 26 rearward starting from the rear end of the first cab frame longitudinal portion 30. The second cab frame longitudinal portion 44 may directly follow the first cab frame longitudinal portion 30 in the forward travel direction of the commercial vehicle 10. The second cab frame longitudinal portion 44 may be an end portion arranged at the rear end of the cab 12 or the cab frame 26.

[0052] Starting from the rear end of the first cab frame longitudinal portion 30, the second cab frame longitudinal portion 44 widens outwardly toward the rear end of the second cab frame longitudinal portion 44 (transversely with respect to the longitudinal axis of the second cab frame longitudinal portion 44). This widening is preferably continuous or substantially uniform over the length of the second cab frame longitudinal portion 44. In other words, the second cab frame longitudinal portion 44 may gradually narrow from its rear end toward the first cab frame longitudinal portion 30.

[0053] For example, the cab 12 or cab frame 26 may form a wedge-shaped profile on the longitudinal portions 30, 44, which expands / widens toward the rear or narrows / taperes toward the front on the cab frame longitudinal portions 30, 44. Preferably, the widening of the cab 12 or cab frame 26 may be uniform on the first and second cab frame longitudinal portions 30, 44.

[0054] Preferably, the plane where the driver's side outer contour of the second cab frame longitudinal portion 44 lies can substantially enclose an inner angle greater than 90° with the plane where the front wall 28 lies. For example, the driver's side outer contour of the second cab frame longitudinal portion 44 and the driver's side outer contour of the first cab frame longitudinal portion 30 can be substantially located in the same plane.

[0055] Preferably, the plane where the passenger side outer contour of the second cab frame longitudinal portion 44 is located can substantially enclose an inner angle greater than 90° with the plane where the front wall 28 is located. For example, the passenger side outer contour of the second cab frame longitudinal portion 44 and the passenger side outer contour of the first cab frame longitudinal portion 30 can be substantially located in the same plane.

[0056] Preferably, the second cab frame longitudinal section 44 may have at least one rear wall flange 46, 48 for the rear wall 54. The at least one rear wall flange 46, 48 may be arranged at the rear end of the second cab frame longitudinal section 44. The at least one rear wall flange 46, 48 may extend discontinuously or continuously over substantially the entire height of the second cab frame longitudinal section 44. The at least one rear wall flange 46, 48 may be aligned in a plane transverse to the central longitudinal axis of the cab 12 or cab frame 26.

[0057] The rear wall flange 46 and the rear wall flange 48 may be opposite to each other. The rear wall flange 46 may be assigned to the driver's side of the second cab frame longitudinal section 44. The rear wall flange 48 may be assigned to the passenger's side of the second cab frame longitudinal section 44.

[0058] The second cab frame longitudinal portion 44 may have at least one side dam flange 50, 52. The at least one side dam flange 50, 52 may be disposed at a rear end of the second cab frame longitudinal portion 44. The at least one side dam flange 50, 52 may be aligned in a plane transverse to a central longitudinal axis of the cab 12 or cab frame 26.

[0059] The side guard flange 50 can be assigned to the driver's side of the second cab frame longitudinal portion 44. The side guard 22 (see Figure 1 ) can be detachably attached to the side guard flange 50, for example fixedly attached or rotatably attached. The side guard flange 52 can be assigned to the passenger side of the second cab frame longitudinal portion 44. The side guard 24 (impact Figure 1 ) may be removably attached to the side guard flange 52, such as a fixed attachment or a swivel attachment.

[0060] The rear wall 54 can be connected to the rear wall flanges 46 , 48 , preferably using a welded connection. The rear wall 54 can be arranged between the rear wall flange 46 and the rear wall flange 48 .

[0061] The cab floor 56 may limit the cab frame 26 on the floor side. The cab floor 56 may be connected to the front wall 28, the first cab frame longitudinal section 30, the second cab frame longitudinal section 44 and / or the rear wall 54, preferably using welded connections.

[0062] Figure 3 Components of the kit system 58 according to an embodiment of the present invention are shown schematically only. As mentioned above, one feature of the kit system 58 is that it can advantageously construct different size versions 12A-12E of the cab 12 or cab frame 26, wherein the different versions have some common components.

[0063] Specifically, the kit system 58 includes the front wall 28 and the first cab frame longitudinal section 30. The front wall 28 is the same or common component for all different versions of the cab frame 26 or the cab 12. The first cab frame longitudinal section 30 is the same or common component for all different versions of the cab frame 26 or the cab 12. Therefore, the front wall 28 and the first cab frame longitudinal section 30 can form a basic module or base module that is the same for all versions.

[0064] from Figure 3 It can be seen that each cab frame 26 obtained / manufactured by the kit system 58 widens from the front toward the rear. The widening can be substantially continuous and / or uniform. The widening portion can be designed as a wedge-shaped profile (wedge-shaped longitudinal section).

[0065] Specifically, the front panel 16 and / or the front wall 28 have, for example, a width B0, which is measured on the transverse axis of the cab 12 or the cab frame 26. The rear end of the first cab frame longitudinal portion 30 has a width B1, which is measured on the transverse axis of the cab 12 or the cab frame 26. The width B1 is greater than the width B0. Therefore, the first cab frame longitudinal portion 30 widens from the front wall 28 toward the rear end of the first cab frame longitudinal portion 30 (e.g., the B-pillars 36, 38). The common length L1 of the front wall 28 and the first cab frame longitudinal portion 30 can preferably extend to the B-pillars 36, 38.

[0066] Figures 4 to 8 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 are shown as examples. The cab versions 12A-12E each have a front wall 28, a first cab frame longitudinal section 30 and a second cab frame longitudinal section 44A-44E of the corresponding version. The dimensions of the second cab frame longitudinal section 44A-44E differ depending on the version. In addition, the cab versions 12A-12E may also each have, for example, a front panel 16, a rear wall 54 and / or side guards 22, 24.

[0067] from Figures 4 to 8 It can be seen that the cab version 12A-12E preferably widens substantially continuously and / or uniformly from the front to the rear. The widening portion can be designed as a wedge-shaped profile (wedge-shaped longitudinal section).

[0068] Specifically, the respective widths B2 to B6 at the rear ends of the respective second cab frame longitudinal portions 44A-44E are larger than the width B0 and larger than the width B1 (see Figure 3 ). Thus, the cab versions 12A-12E widen from the front wall 28 towards the rear end of the respective second cab frame longitudinal portion 44A-44E, respectively; wherein the second cab frame longitudinal portion may end at the rear wall 54, for example.

[0069] The second cab frame longitudinal sections 44A-44E and thus the cab versions 12A-12E may have different lengths. For example, the second cab frame longitudinal section 44A and thus the cab 12A may be shorter than the second cab frame longitudinal section 44B and thus the cab 12B (see Figure 4 and Figure 5 The second cab frame longitudinal portion 44B and thus the cab 12B may be shorter than the second cab frame longitudinal portion 44C and thus the cab 12C (see Figure 5 and Figure 6 ),etc.

[0070] For example, the second cab frame longitudinal portions 44A-44E may be widened in different ways due to their different lengths L2-L6. For example, the width B2 of the rear end of the second cab frame longitudinal portion 44A and thus the width B2 of the cab 12A may be smaller than the width B3 of the rear end of the second cab frame longitudinal portion 44B and thus the width B3 of the cab 12B (see Figure 4 and Figure 5 ). The width B3 of the rear end of the second cab frame longitudinal portion 44B and thus the width B3 of the cab 12B may be smaller than the width B4 of the rear end of the second cab frame longitudinal portion 44C and thus the width B4 of the cab 12C (see Figure 5 and Figure 6 ),etc.

[0071] therefore, Figures 4 to 8 Several different length and width versions 44A-44E of the second cab frame longitudinal portion 44 are shown.

[0072] Preferably, all cab versions 12A-12E have the same rear wall 54. This can preferably be achieved by the fact that the rear wall 54 can be connected (preferably welded) to the different versions 44A-44E of the second cab frame longitudinal section 44 via the rear wall flanges 46, 48. Then, the rear wall flanges 46, 48 can be designed identically for all versions 44A-44E of the second cab frame longitudinal section 44. In particular, the rear wall flanges 46, 48 in all versions 44A-44E of the second cab frame longitudinal section 44 can have the same distance (y distance or distance in the cab transverse direction) from the central longitudinal axis of the second cab frame longitudinal section 44A-44E.

[0073] Preferably, all or at least some of the cab versions 12A-12E may have identical side dams 22, 24. This is preferably achieved by the fact that the side dams 22, 24 may be connected (preferably, fixed) to the different versions 44A-44E of the second cab frame longitudinal section 44 via side dam flanges 50, 52. The side dam flanges 50, 52 may then be designed identically for all versions 44A-44E of the second cab frame longitudinal section 44.

[0074] All cab versions 12A-12E can have the same cab door 20. This is preferably achieved by the fact that the cab door 20 can be movably, preferably pivotably connected by its at least one door flange 40, 42 to the first cab frame longitudinal section 30 designed as an identical component and / or the front wall 28 designed as an identical component.

[0075] Furthermore, the kit system 58 may include different length versions of the cab floor 56 and / or the cab roof 18 depending on the versions 12A-12E of the cab 12 and thus on the versions 44A-44E of the second cab frame longitudinal portion 44 .

[0076] The invention is not limited to the preferred embodiments described above. On the contrary, there are numerous variants and modifications which also exploit the idea of ​​the invention and therefore fall within the scope of protection. In particular, the invention also claims the subject matter and features of the dependent claims independently of the cited claims. In particular, the individual features of independent claim 1 are disclosed independently of one another. Furthermore, the features of the dependent claims are also disclosed independently of all the features of independent claim 1 and are disclosed, for example, independently of the features in independent claim 1 relating to the presence and / or configuration of the front wall, the first cab frame longitudinal portion and / or the second cab frame longitudinal portion.
