Definitions
- the invention relates to a vehicle, in particular a utility vehicle for the transportation of goods or people, comprising a utility module and a plurality of driving modules. Furthermore, the invention relates to a driving module and a useful module for such a vehicle and a method for providing such a vehicle with such a useful module and such driving modules.
- a commercial vehicle with a modular structure which comprises a front module, a cargo module and a drive module, the module elements being connected to one another in the longitudinal direction of the vehicle, and a modular system for such a commercial vehicle.
- a payload transport vehicle consisting of a power steering module, an energy module, an electrical module and an impeller module, the modules being rigidly connectable to one another via uniform connection points and each having the same length.
- DE 44 19 602 A1 describes a method and equipment required for carrying out in-house delivery of consumers with goods, the method being based on the use of circulating containers and vehicles with special equipment which transport these containers to the customer. Vehicles of the type described require maintenance and servicing, with most damage to such vehicles occurring in the area of the chassis, the drive, the brakes or a control of the vehicle.
- the task is to simplify the maintenance and repair of commercial vehicles and to increase the operating time of the vehicles.
- the object is achieved by a vehicle with the features of claim 1, by a driving module with the features of claim 8, by a useful module with the features of claim 11 and by a method for providing a vehicle with the features of claim 14.
- a vehicle is made available which is of modular construction and which comprises a useful module and a plurality of driving modules.
- the useful module is e.g. B. tet for the transport of goods or people.
- the driving modules include functionalities that only make it possible to drive the vehicle.
- the useful module and the driving modules are each designed as separate vehicle modules that can be coupled with one another.
- the useful module is free from the chassis and coupled to at least two of the driving modules to enable the vehicle to be driven. At least one of the driving modules has its own drive.
- the invention further relates to a driving module and a utility module for a vehicle of the type described above.
- the driving module is set up to be coupled to the chassis-less useful module in order to enable the vehicle to be driven if the useful module is coupled to at least one further driving module.
- the useful module has no chassis and is set up to be coupled to at least two driving modules in order to enable the vehicle to be driven.
- the method according to the invention for providing a vehicle basically comprises the following steps: Providing a useful module;
- rail vehicles in particular come into question.
- the invention is also applicable to motor vehicles in road traffic.
- the invention offers a number of advantages. These become particularly clear when you first consider conventional vehicle concepts for commercial vehicles. Today, these consist almost exclusively of specific car body constructions adapted to the respective application cases, which include an integration of the trolleys as a construction element. As a result, the constructions are complicated to manufacture due to the installation space for the undercarriage to be left out, or force restrictions in the usable space. Structural strength and driving dynamics requirements must be met through reinforced and heavy-duty constructions. Furthermore, operational experience shows that faults are often in the area of the chassis / drive / brake unit, which means that a fault binds an entire vehicle there for maintenance. This applies in particular to low-floor vehicles that have a floor height in the usable space below the height of the wheels of the vehicle.
- the present invention basically solves the problems described by decoupling the usable space and the chassis / drive / brake unit.
- the usable space is provided in a usable module which is coupled as a separate vehicle module for providing the vehicle with a plurality of drive modules which are also present as separate vehicle modules, such a drive module then being able to comprise a chassis / drive / brake unit.
- the utility module on the other hand, is itself without a chassis, so it does not include wheels, tracking elements, a drive or one Brake.
- the driving modules can then provide them with the necessary equipment for driving the vehicle by coupling them to the useful module.
- the useful module comprises a plurality of separate partial useful modules coupled to one another.
- the partial useful modules can be designed identically.
- Each of the partial useful modules can be set up to serve itself as a useful module, i. H.
- each of the partial useful modules can be set up to be coupled to at least two of the driving modules in order to form a vehicle according to the invention.
- the partial utility modules can each be chassis-less. But it is also possible that, for. B.
- two or three partial useful modules can be coupled in series (based on a direction of travel) to form a useful module, a vehicle according to the invention then being formed in which a first driving module is coupled to a front of the first partial useful module and a second driving module to the Rear of the (based on a direction of travel) rearmost utility module is coupled.
- the drive modules can be separated from the user module and exchanged in a short time.
- this enables separate, flexible use of driving and utility modules.
- the maintenance-intensive part of the vehicle is concentrated in a compact unit that can be replaced quickly and can be brought separately for maintenance.
- the useful module remains fully usable.
- the module can also be flexibly expanded.
- the possible arrangement of the driving modules on both sides of the useful modules further maximizes the useful space. In this respect, maintenance and servicing of commercial vehicles are simplified and the operating time of the vehicles is increased.
- the vehicle preferably comprises (based on a direction of travel) a driving module in each case on the front and the rear of the useful module.
- a driving module in each case on the front and the rear of the useful module.
- the arrangement of the drive modules on both sides of the useful modules further maximizes the useful space.
- the driving modules arranged on the front and rear of the vehicle are of identical design. This enables flexible use of each driving module and reduces the complexity of the structure. In this way, a driving module can be coupled equally on both sides of the useful module.
- one of the driving modules and the useful module are each coupled to one another via a uniform interface. All relevant energy, control and communication functions on the front and rear of the user module can be accessed via the interface.
- the utility module can additionally contain suitable independent sensors, control units and devices, e.g. B. for air conditioning, passenger change, lighting, passenger information, security, logistics, etc.
- two above-mentioned utility modules can be coupled together via a further uniform interface. The further one
- the interface can match the interface between the useful module and the driving module.
- different types of Fahrmo modules can be provided, z. B. only some of the driving modules have a drive function, and other driving modules are designed only for carrying and guiding the useful module. In this way, the costs of the overall construction of the vehicle can be reduced.
- a lower edge of a usable space of the useful module when the useful module is coupled to the at least two driving modules, is arranged at a height which is lower than a height of wheels of at least one of the driving modules, which enables the vehicle to be driven - borrowed.
- This embodiment allows, for example, in the event that the vehicle is used for passenger transportation, facilitating boarding and alighting of the passengers, or in connection with a cargo transportation, a simplified loading and unloading of goods.
- the available usable space can be increased in this way.
- a driving module usually includes one or more of the following elements:
- a tracking element a brake
- Elements for carrying and guiding the vehicle can be designed differently. Possible embodiments are e.g. B. a continuous wheel set with axle, a single wheel chassis or the like. There are no restrictions in the useful module because the driving module is separated from the useful module.
- the drive of the at least one driving module of the vehicle can, for. B. include a drive control, a converter, a motor and / or possibly a transmission.
- a driving module individual or all elements of the brake can be included, such as brake control and brake actuators.

- a partial or complete energy supply for supplying functions of the driving module can be present in a driving module.
- the energy transfer can be adapted to the conditions of the infrastructure. It is conceivable, for. B. a continuous supply via a catenary. It is also possible to selectively supply a suitable energy storage device for the driving module from a charging point, e.g. B. via electrical contacts or inductively.
- a supply via fuel cells and / or batteries can also be implemented in the driving module. From the energy supply of the driving module or the driving modules, an additional energy supply for the useful module can take place. Alternatively or additionally, the useful module itself can have its own energy supply.
- a control in a driving module can contain individual or all functions that are necessary for the operation of the vehicle (also autonomous operation). This can also include sensors, communication facilities and processing intelligence, e.g. B. for drive, steering, braking, energy supply, charging management, communication in the vehicle and to the outside (z. B. V2X), and other vehicle functions, such as. B. lighting, count.
- the controller can also perform control functions for the useful module or the partial useful modules via the uniform interface explained above.
- the useful module preferably does not include any of these elements of the driving module, at least not the wheels, lane guidance, drive or brake.
- the user module generally contains those functions that are necessary for the respective application (e.g. goods transport, passenger transport).
- the utility module can additionally contain suitable independent sensors, control units and devices, e.g. B. for air conditioning, passenger change, lighting, passenger information, security, logistics.
- the design of the utility module can be similar to a container, with unified connection areas and interfaces for additional vehicle modules, such as a driving module or a partial utility module.
- the useful module and driving modules can be coupled with one another in different ways.
- one of the driving modules is coupled to the useful module in that the driving module is docked onto an end face (front or rear side) of the useful module.
- the useful module is mounted on the driving module.
- a mechanical connection of a driving module with the useful module can be done via predefined mechanical joints or fixed connecting elements in combination with e.g. B. a steerable chassis.
- the maintenance-intensive part of the vehicle (the driving module) is concentrated in a compact unit that can be replaced quickly and can be brought separately for maintenance. As a result, the entire useful module remains usable.
- the arrangement of the driving modules on both sides of the useful modules maximizes the useful space.
