Description

Modular construction cab structure series

technical field

The invention relates to a modular driver's cab arrangement according to the preamble of claim 1 .

Background technique

From DE 101 18 344 A1 a series of modularly constructed driver's cab structures for trucks is known for forming driver's cab variants of different sizes. In this case, there is a base module, which is designed uniformly in all cab variants, and an add-on module which can be added to it and which has different length dimensions for each cab variant. The base module has a front wall, two side walls each with a door and a door frame, a base and a front roof section, which is designed to be open towards the rear and has a ring-shaped closed first flange area behind it . On the other hand, the add-on module has a rear wall, two side wall sections, a base section and a rear roof section, is designed to be open towards the front and has an annular closed second complementary to the first flange area at the front. Two flange areas. In the add-on module, the side wall sections, floor section and roof section have different length dimensions for each cab variant.

From DE 43 02 489 A1 known series of driver's cabs of modular construction for trucks, comprising cabs of different length, width and height dimensions. In this case, different roof racks are provided, which can optionally be connected to the common cab base part via or without an intermediate part, detachably or non-detachably. The side cab walls and the rear cab wall are formed in the connection area of the roof rack as a profile frame which is surrounded on three sides and reinforces the roof rack area and which is passed through a separate profile bow on the side of the cab front wall (Profilbügel) is completely closed.

Known from DE 38 23 161 A1 is an assembly of an air deflector for a cargo vehicle, in particular for a saddle tractor, which has cabs of different external dimensions and semi-trailers of different heights. In order to reduce the airflow resistance of the truck and to achieve an overall closed profile with the same airflow characteristics, it is recommended to use air guides at the transition between cabs of different external dimensions and connected semi-trailers of different heights. The wind deflector consists of a height-adjustable wind deflector which is arranged on the rear part of the cab roof and which is uniform in size for all cab variants, a uniform which is fixed adjustable to the side of the rear wall of the cab The wind deflector and the unified intermediate element that connects them are arranged between the wind deflector and the cab roof and between the wind deflector and the wind deflector.

From US 6,178,612 B1 a method is known for installing or removing a sleeping cabin (Schlafkabine) on a truck. For this purpose, the rear wall of the cab of the truck is designed to be removable and in the removed state can be replaced by a sleeping compartment which can be easily connected to the cab of the truck. The truck can thus be easily and quickly adapted to different requirements such as short-distance or long-distance transport. The conversion work that can be carried out on the truck cab is mainly limited to the removal or installation of the removable rear cab wall and the installation or removal of the sleeping and/or cabin.

Contents of the invention

The technical problem addressed by the invention is to provide an improved embodiment for a modular driver's cab series of the type mentioned at the outset, in which, in particular, the variant design for the driver's cab is simplified.

This object is solved by the subject-matter of the independent claims, advantageous configurations are the subject-matter of the dependent claims.

The invention is based on the general idea that for a modularly constructed series of cab structures with an essentially uniform cab base module, a modularly constructed cab roof is provided which is supported by a transverse bow frame (Querspriegel ) into a front roof area with a front roof module and a rear roof area with a rear roof module. Here, at least two different front roof modules and/or two different rear roof modules are provided, which differ from one another at least in terms of their shape and/or function and thus enable a variable structure of the driver's cab roof. possible.

The basic driver's cab module has a front wall, two side walls as well as a rear wall and a driver's cab floor, wherein the transverse bracket according to the invention connects the two side walls on the roof side in the region of the B-pillars of the two side walls. The two side walls, however the transverse bow frame are integral parts of the modular cab canopy.

The front roof module in the direction of travel and the rear roof module in the direction of travel are connected to the front of the transverse bow, which are of the same or different type and form a continuous connection with the transverse bow in one embodiment. The outer surface of the canopy.

This offers the advantage that the modularly constructed cab roofs of the cab construction series can be adapted to different requirements by simply exchanging one or two roof modules. In particular, it is thus possible to adapt a rear region of the roof to the vehicle body by means of a correspondingly designed rear roof module. The front roof module and the rear roof module can here independently of one another have different heights or different roof shapes.

The solution according to the invention overall provides the advantage that an identical basic module of the driver's cab series is used during the production process and is only passed through a differently designed transverse bracket and/or in subsequent production steps. Or adapt it to the requirements subsequently imposed by commercial vehicles by means of different roof modules. The possibility of subsequent variant formations in the production process makes the production process more flexible and additionally allows the production process to be simple and rational.

Thus, for example, the manufacturing process can be intervened at a very late stage of manufacture and the cab can be retrofitted into a cab with a very low roof by changing the transverse bow or roof modules of a cab with a standard roof (e.g. for car transporters).

According to a preferred embodiment of the solution according to the invention, a variant of the front roof module can be used as a rear roof module or vice versa. This makes it possible to provide roof modules not only for the rear roof opening but also for the front roof opening, which are respectively roof modules for the other roof opening. As a result, structurally identical roof modules with uniform dimensions are produced, so that the flexibility during the production process and also with respect to subsequent retrofitting of the driver's cab roof can be significantly increased. At the same time increasing the number of identical parts that can be manufactured more rationally and cheaply.

It can be expediently provided that the front roof module and/or the rear roof module are formed as an aggregate frame. This offers the advantage that the roof module can already be prepared at the factory and thus securely and securely fasten the assembly to be supported, for example a driver's cabin air-conditioning system, an additional heating system or a cooling system for the body. Subsequent complex and expensive retrofitting work on the subassembly frame can thus be dispensed with. At the same time, it is also possible in principle to adapt the truck to the new requirements by simply exchanging the roof module when it is repurposed.

Furthermore, it is provided that the front roof module and/or the rear roof module are formed as wind guide bodies. In particular, commercial vehicles with a large load space volume, such as furniture vans, present a high flow resistance and thus high fuel consumption. By forming the front roof module and/or the rear roof module as an air guiding body, the airflow resistance of the commercial vehicle can be significantly reduced and thus cost saved. It applies here that, analogously to the embodiment described above, the driver's cab can be adapted to changing usage requirements by exchanging the roof module during the manufacturing process and in particular also afterwards.

Overall, according to other advantageous embodiments, other variants of the front roof module and/or the rear roof module can be provided, for example as a loading space and/or as a berth compartment.

According to a preferred embodiment, at least two transverse brackets of different types are provided. According to an embodiment variant, the transverse bow can form an identical component of the outer surface of the roof, which in different types of configurations, for example with different heights, mainly influences the shape of the roof of the driver's cab structure series. Here, for example, a transverse bow is conceivable, which significantly increases the height of the driver's cab and thus also creates space for objects to be loaded into the vehicle or for a sleeping compartment. A further transverse bracket extending substantially at the same height as the upper end of the side walls makes it possible, for example, to use the driver's cab for a car transporter.

According to a particularly advantageous embodiment of the invention, at least one roof module has a roof window. Roof windows are nowadays often custom-made as additional equipment for automobiles and increase the driver's driving comfort through an additional, roof-side, natural light incidence and also avoid the sense of isolation that often occurs in modern cockpit cabins .

Further important features and advantages of the invention emerge from the subclaims, the drawings and the accompanying description of the figures with the aid of the drawings.

It goes without saying that the features mentioned above and those still to be explained below can be used not only in the respective combination mentioned but also in other combinations or on their own without departing from the scope of the present invention.

Description of drawings

A preferred exemplary embodiment of the invention is depicted in the drawing and will be explained in more detail in the ensuing description, wherein identical reference numbers refer to identical or similar or functionally identical components. in:

Figure 2 is a view as in Figure 1, but in another embodiment.

Detailed ways

According to FIG. 1 , a modularly constructed cab 1 according to the invention of a series of cab structures for commercial vehicles has a substantially uniform base module 2 with a front wall 3 and two side walls. 4, 4' and a rear wall 5 and a cab floor 6. The base module 2 of the driver's cab 1 can be fitted to different vehicle chassis, not shown, so that completely different commercial vehicles can be realized. The two side walls 4 , 4 ′ each have a door opening, on which a vehicle door (not shown) can each be arranged. Furthermore, the two side walls 4 , 4 ′ are connected to one another at a front end viewed in the direction of travel by the front wall 3 and at a rear end viewed in the direction of travel by a rear wall 5 in the transverse direction of the commercial vehicle.

On the roof side, the base module 2 has a transverse bracket 7 which connects the two side walls 4 , 4 ′ and is arranged on the side walls in the region of their B-pillars. The transverse bracket 7 also reinforces the driver's cab 1 in the transverse direction, is a component part of the modularly constructed driver's cab roof 8 and forms part of a roof outer surface.

According to FIG. 1, the modularly constructed cab roof 8 is formed by a front roof module 9, a rear roof module 10 and a transverse bracket 7, which is connected to the front roof module 9 on the one hand and On the other hand, it is connected to the rear roof module 10 and separates them from each other. An upper frame section 11 of the front wall 3 , a front upper region 13 , 13 ′ of the two side walls 4 , 4 ′ and the transverse bracket 7 serve as support surfaces for the front roof module 9 on the base module 2 Or connecting surfaces, the respective rear upper regions 14, 14' of the two side walls 4, 4', a not-detailed upper region of the rear wall 5 and likewise the transverse bow 7 serve as rear roof modules 10 Support or connecting surface on the base module 2 .

According to the description in FIG. 1 , the front roof module 9 , the transverse bow 7 and the rear roof module 10 form a continuous outer surface of the roof. The two roof modules 9 and 10 can be designed in such a way that a variant of the front roof module 9 can be used as a rear roof module 10 or vice versa. Usually at least two different front roof modules 9 and/or two different rear roof modules 10 are provided, which differ from each other at least with respect to their shape and/or their function.

The base module 2 shown by way of example in FIG. 1 is designed such that the transverse bracket 7 divides the modular cab roof 8 essentially in half. However, an embodiment variant is also conceivable in which the front roof module 9 is longer or shorter than the rear roof module 10 and thus the transverse bracket 7 divides the driver's roof 8 into two differently sized roof surfaces.

According to different embodiment variants, the front roof module 9 and/or the rear roof module 10 can be designed, for example, as an assembly frame, for example for a not shown driver's cabin air conditioning system, a not shown auxiliary heating system or cooling unit. However, it is also conceivable that at least one of the two roof modules 9 , 10 is formed as an air guiding body. Such an air guiding body (not shown) is adapted to the corresponding bodywork of the commercial vehicle and reduces its airflow resistance and thus energy consumption.

In addition or as an alternative, other embodiments of the roof modules 9 , 10 according to the invention are conceivable, for example as loading spaces or as sleeping compartments.

The simple interchangeability of the two roof modules 9 and 10 achieves a high degree of flexibility during the production process and also in principle also simplifies possible retrofitting of the truck, for example in the event of a change of use. If, for example, a truck that has hitherto been used as a grocery transport vehicle is to transport frozen food in the future, after the body has been replaced, only the rear roof module 10 has to be replaced by a roof module 10 designed as an assembly frame. The necessary cooling devices for cooling the body can now be fitted to the roof module. If it is also desired to improve the aerodynamic drag, the front roof module 9 can be replaced by a corresponding roof module 9 with an air guide. A broad field of application of the solution according to the invention and the advantages associated therewith can be appreciated from this example.

In addition, the solution according to the invention offers the advantage that the manufacturing process can be significantly rationalized by producing and prefabricating an essentially uniform base module 2 and only adapting the modularly constructed driver's cab roof 8 to the subsequent special requirements.

FIG. 2 shows another embodiment of a modularly constructed cab roof 8 . Compared to FIG. 1 , the front roof module 9 , the transverse bow 7 and the rear roof module 10 have almost no arch. This results in a significantly reduced roof height, which is particularly advantageous in car transport vehicles, since the space above driver's cab 1 can thus also be used as a loading space.

According to an embodiment variant, a roof window 12 can be provided on the front roof module 9 and/or on the rear roof module 10, through which natural or colored sunlight enters the driver's cabin 1 and thus increases driving comfort. sex.

In summary, the main features of the inventive solution can be as follows:

The invention proposes that a modularly constructed driver's cab 1 is provided with a modularly constructed driver's cab roof 8, said driver's cab essentially having a uniform base module 2 comprising a front wall 3, two side walls 4, 4' and a rear wall 5. The modularly constructed cab roof 8 comprises a transverse bow 7, a front roof module 9 and a rear roof module 10, said roof module being arranged in front of or behind the transverse bow 7 as viewed in the direction of travel, so that The transverse bracket connects the two side walls 4 and 4 ′ in the region of the B-pillar and at the same time forms part of the outer surface of the roof. At least two different front roof modules 9 and/or two different rear roof modules 10 are provided here, which differ from each other at least with respect to their shape and/or their function.

The roof modules 9 and/or 10 can be formed here, for example, as an assembly frame for a cooling device, as an air guide, as a loading space or as a sleeping compartment.
