Definitions
- the present invention relates to an end wall module for a motor vehicle and a motor vehicle.
- a motor vehicle has a self-supporting body, the body having a so-called “end wall” to delimit the vehicle interior in the direction of travel, which e.g. is designed as a sheet steel belonging to the body.
- a steel sheet is regularly connected at its upper end to a hollow support (a so-called “window bow”) which is arranged above the front wall and which represents the lower connection surface for a windshield of the motor vehicle.
- This conventional design has the advantage that a body can be prefabricated essentially liquid-tight and with a rigid structure. adversely is, however, that functional units in the area of the end wall, such as a blower for interior ventilation, parts of the vehicle electronics, etc., have to be individually mounted on the end wall in a very complex manner. This results in high costs in production, and the replacement of individual functional units is also very expensive.
- GB 2329363 A shows an end wall module for a motor vehicle. This forms the upper region of an end wall of a motor vehicle which delimits the motor vehicle interior.
- This end wall module has a blower for interior ventilation as a functional unit in its interior.
- This known end wall module has the advantage that it reduces the manufacturing outlay, since functional units can be inserted into the motor vehicle in a prefabricated manner.
- this concept does not fully meet high security requirements.
- it can be problematic during assembly to bring the known end wall module through the motor vehicle interior into the region of the end wall.
- the present invention is therefore based on the object of providing an end wall module for motor vehicles or a motor vehicle which can be produced and repaired inexpensively, but nevertheless fulfilling high safety requirements.
- an end wall module according to the preamble additionally has a yoke support, which can be connected to two side members of the motor vehicle, an inexpensive and safe concept is provided.
- the yoke carrier according to the invention contributes to the torsional rigidity of the motor vehicle about the longitudinal axis, as a result of which the driving comfort and the
- the yoke support is non-positively connected to the remaining end wall module, e.g. can be connected via screws.
- the yoke support can be easily manufactured from a very stable material (e.g. a profiled sheet steel) and easily connected to the rest of the end wall module e.g. be screwed. This is easily possible, in particular on the outside of the bulkhead module, ie towards the engine compartment in front-engine vehicles.
- a possible separation of the yoke carrier and the rest of the end wall module also makes it possible to couple only different yoke carriers for different motor vehicle rows, but otherwise the same end wall modules with one another.
- non-positive connection preferably screw connection
- a glue may also be useful for sealing
- the yoke beam can be connected to the longitudinal beams of the motor vehicle in a force-locking manner, preferably by means of screws. This is of particular advantage both in vehicle manufacture and when replacing the bulkhead module. It is possible that at a relatively late stage of strength vehicle production the bulkhead module is used completely (namely "from above"), from the area of the engine compartment (for front engines). Welding is not necessary here, automotive paint is not damaged. It is particularly advantageous here that the side members of the motor vehicle provide a connection surface for the yoke member, under certain circumstances it is also possible to weld corresponding attachments to the side members during the previous bodywork manufacture, which offer additional stability in the connection area.
- Such attachments also make it easy, for example in the case of bulkhead modules with a uniform yoke beam size, to accommodate one and the same bulkhead module (with an identical yoke beam) in bodies of different sizes by varying the attachments.
- positive or material connections in particular adhesive bonding
- a particularly advantageous development provides that several functional units are accommodated in the end wall module.
- This can e.g. one (or more) blowers for interior ventilation, an interior air filter, a radiator for interior ventilation, an evaporator of an air conditioning system, an air duct system, a control unit for electrical control of elements in the motor vehicle interior, a wiring harness connected to the control unit, an airbag or like.
- the end wall module has so-called "collectors" which are connected to the cable harness or to the control unit. These collectors can serve as electrical interfaces between the bulkhead module and the rest of the motor vehicle (for example with elements of the engine electronics, door locking, lighting, etc.). These collectors can, for example, be attached to the lateral outer sides of the bulkhead module, which makes it particularly easy to connect standardized data buses to the collectors. By simply exchanging the collectors, electrical or electronic connection of the bulkhead module to various model series is also possible.
- the end wall module has a cavity structure with an outer shell, the outer shell being formed by an end wall inner part oriented towards the motor vehicle interior and an outer end wall part facing away from the motor vehicle interior.
- the bulkhead module itself also contributes to stiffening and improving the safety of the motor vehicle.
- the outer end wall part and / or inner end wall part are connected as a hybrid part made of metal with plastic connected thereto (e.g. in honeycomb construction). This results in simple manufacturability, material separation during reuse is facilitated, and the manufacturing costs are low.
- other supporting parts e.g. a hollow support to be provided in the upper area of the end wall module, which performs the function of a "window arch" there.
- a window bow which has already been fixed beforehand, makes it even easier to assemble the end wall module (“from above”, ie not necessarily from the vehicle interior).
- the end wall module according to the invention can be used in different types of motor vehicles.
- a profiled or steel sheet composite provided with cavities is provided.
- the steering unit is virtually separated from the body-in-white, a right-hand or left-hand drive vehicle can be realized simply by providing different end wall modules during manufacture, and retrofitting is also easily possible.
