Definitions
- the invention relates to a vehicle chassis for a land vehicle, in particular for a motorhome or a recreational vehicle.
- a disadvantage of corresponding chassis is that the static properties are often tuned over the entire course of the chassis, which provides little flexibility in the construction of superstructures and the required model variety, especially in motorhomes.
- Object of the present invention is to develop a vehicle chassis such that in particular with regard to the variety of models and the flexibility of the structure can be made easier and cheaper.
- this object is achieved by a vehicle chassis for a land vehicle, in particular for a motorhome or a recreational vehicle, wherein the
- Vehicle chassis comprises a front chassis module and a rear chassis module, wherein the rear chassis module comprises at least two sub-modules.
- the front chassis module can be designed as a power head in semi-integrated connection or fully integrated version.
- the front chassis module in particular the drive head, is connected to the rear chassis module via at least one flange means to form the entire vehicle chassis.
- the rear chassis module comprises and forms supporting components of lightweight construction material
- Components at least two sub-modules.
- One of them is configured as a frame module, another as an axle pan module and these modules can be combined to form the rear chassis module such that the frame module is connected to the front chassis module and the axle pan module to the frame module connected.
- Components of the rear chassis module at least partially, but in particular completely made of composite materials, in particular a laminate are constructed.
- Components offers an almost unlimited variety of shapeable geometries with high stability and low weight. In addition, are appropriate
- the frame module at least two, preferably four bearing
- the supporting frame elements which pass through the frame module, provide the necessary statics for the structure to be applied, for example a motorhome. In addition, these serve to attach the respective others
- the load-bearing frame elements provide the necessary static properties.
- the Achswannenmodul as a self-supporting tub, in particular as a laminate tub from a Composite materials is constructed.
- the term of the tub is to be understood broadly, so that a substantially U-shaped axle well module applies as tub in the context of the invention.
- the design of the axle well module of a composite material, in particular as a laminate tub allows a flexible and immediate adaptation to the required geometry.
- the condition for connection to the frame module on the other hand also created to accommodate corresponding axle elements, such as a rigid axle or independent suspension. It is particularly necessary that the introduction of the forces generated by the axis in the Achswannenmodul and the further introduction of the resulting forces in the other components of the chassis are defined, so that the connection of the axle pan module can remain standardized to the other components.
- the rear chassis module has at least one further sub-module, in particular a rear module, wherein the further sub-module is connected to the axle pan module.
- Dimensioning of the relevant rear garage can be flexibly selected, and can be adapted to the respective requirements of the floor plan or the model variety.
- axle tray module is designed to be free of longitudinal members in its interior.
- axle tray module Due to the design of the axle tray module free of inner longitudinal members, thus by the formation of the axle tray module as a self-supporting static element is in the area of this chassis module an expanded storage space for
- Achachswannenmodul is achieved, regardless of the arranged construction of the axle and their dimensions or the dimensioning of the entire chassis, can be achieved that controlled forces are introduced into the frame module, so that the frame module, in particular its connections to the axle pan module, but also the Connection to the front chassis module (eg the power car) can be standardized.
- the respective differences of different chassis designs or axles are absorbed by the inherent static design of the axle pan module and uniform forces are introduced.
- At least one sub-module in particular a plurality of sub-modules are formed such that standardized receptacles between the modules allow any connection of the modules to each other.
- the sub-modules for example the frame module
- the sub-modules can be combined with an additional module and extended.
- the idea of the modular design of different chassis for different models of vehicles is supported by the independent of the submodule standardized inclusion of the modules with each other, as various modules are useful together freely combinable.
- special modules e.g. be created with increased need for longitudinal cargo space for sports equipment or stability for special extensions.
- At least one sub-module in particular a plurality of sub-modules in their material properties and / or
- Geometry are formed such that all acting on the sub-module forces are recorded in a controlled manner and via standardized connections, if necessary to adjacent sub-modules can be transmitted.
- the modular character allows for independent geometric and static planning of the sub-modules, since the forces transmitted through the connections are standardized, thus from the Module combination are independently detectable.
- the modular construction of the rear chassis module by means of its submodules which can be combined in any desired manner, makes it possible to provide a modular system which is characterized by standardized connections and standardized force effects
- Fig. 1, 1 a is a schematic representation of the three attached to each other
- Fig. 2 is a schematic exploded view of the components of
- FIG. 1 shows a schematic representation of a rear chassis module 1.
- the rear chassis module 1 is shown once in a composite representation 2 in FIG. 1 and once in its modules in a spatially separated manner from one another in FIG. 1 a.
- the rear chassis module 1 comprises a frame module 3, a
- Axle tray module 4 and a rear module 5 are identical to Axle tray module 4 and a rear module 5.
- Both the frame module 3 and the axle tray module 4 include
- the axle tray module 4 has an axle receptacle 8, shown schematically, on which the axle or the wheel suspension are guided.
- the axle tray module 4 is connected at its front side 10 to the frame module 3 at its rear side 11. Due to the integral static design of the axle pan module 4, a defined introduction of force is always formed on the frame module 3 at the transition 10-1 1, regardless of which dimensioning or type of axle or Chassis in the axle 8 is provided.
- a flange means 12a, 12b is provided on each longitudinal side on the side wall 6a, 6b, which serves for attaching the rear chassis module 1 to a front chassis module, for example a power head.
- a rear module 5 shown schematically here, is connected via projecting receptacles 13a, 13b.
- the rear module has a U-shaped cross-sectional profile rotated by 90 ° to the longitudinal direction of the vehicle, since it is generally used to form a rear garage to be loaded laterally.
- the rear module 5 is present with static stiffening
- Longitudinal channels 14a and 14b provided, which defines the load of the rear module 5 defined in the receptacles 13a and 13b and thus in the axle tray module 4.
- Fig. 2 shows a schematic representation of a chassis 19.
- Chassis module 20 which is designed here as a drive head chassis, is connected to a rear chassis module 21.
- Flange means 22a and 22b for attaching the rear chassis module 21 are attachable to the front chassis module 20.
- the rear chassis module 21 comprises an axle well module 24 and a rear module 25.
- the frame module 23 is shown here in a modified representation. In this case, it comprises a subfloor 26, on which supporting frame elements 27a, 27b, 27c and 27d are arranged.
- the sub-floor 26 and the supporting frame elements 27a to 27d form the frame module 23.
- the frame module 23 and the axle well module 24 and possibly the rear module 25 at least partially overlapping a running floor 28 is provided which covers the chassis in its structure.
- the frame elements 27a to 27d pass through the area of the present invention
- Frame elements 27a to 27d which is the static property of the frame module 23 determine, defined passes. In this way, the dimensioning and attachment to the frame members 27a to 27d can be performed standardized, regardless of which chassis or axle construction is used. Due to the modular design, it is now possible to adapt both the frame module 23 and the axle well module 24 or the rear module 25 in its dimensioning according to the desired model of the vehicle to be constructed.
- the frame module 23 may vary in length over a wide range, and thus influence the wheelbase of the vehicle.
- the axle well module 24 may, as described above, be formed either for receiving a rigid axle or for receiving independent suspension or dual axles, without making total adjustments to the frame module 23 or the rear module 25 must be made.
