Description

[0001] The invention relates to a body component for a driver's cab of a motor vehicle, comprising a floor structure component. The floor structure component has a rear side, a front side opposite the rear side, two sides (a first side and a second side opposite the first side), a bottom side, and an upper side opposite the bottom side. A front component is connected to the floor structure component at its front, and a rear component is connected to the floor structure component at its rear. The invention further relates to a motor vehicle with a chassis to which a drive component is attached and with a driver's cab comprising the aforementioned body component.

[0002] A commercial vehicle, particularly a truck, typically comprises a chassis, a driver's cab, and a drive system for propelling the vehicle. The drive system and the driver's cab are connected to the chassis, with the drive system projecting upwards from the chassis. The driver's cab typically includes a body section with a floor structure, the floor structure having a raised center section. This raised center section forms a receptacle for the drive system located beneath the floor structure. The drive system projects into this receptacle, allowing the driver's cab to be mounted onto the chassis.

[0003] The floor structure component is dimensioned and designed such that forces acting frontally on the vehicle, particularly on a frontal body component, especially in a frontal impact, are transferred via the floor structure component to a rear body component, thereby distributing the forces across the entire body component. This is intended to reduce the risk of injury to the driver and ensure the structural integrity of the driver's cabin.

[0004] Because the driver's cab is positioned relatively high above the road surface, entry into the driver's cab is comparatively uncomfortable.

[0005] The generic patent DE 10 2023 108 144 A1 describes a commercial vehicle comprising a chassis frame, a driver's cab, and a technical tower located behind the driver's cab on the chassis frame. The crash forces are intended to be directed to the technical tower along a force path parallel to a frontal impact via a longitudinal component running from front to rear along the cab floor.

[0006] WO 2019 / 219179 A1 shows a cab mounting of a commercial vehicle with a support attached to the chassis frame of the vehicle to support the cab and a deformation element to absorb frontal forces in an accident.

[0007] Furthermore, DE 197 47 940 B4 shows a commercial vehicle with a chassis frame connected to a drive unit, on which a driver's cab is mounted. Behind the drive unit, the chassis frame has a stop that transfers the forces acting on a bumper in a frontal collision into the chassis frame.

[0008] Furthermore, DE 40 32 823 A1 discloses a distribution vehicle with a driver's cab whose rear wall forms a frame interface between a drive unit frame that supports the driver's cab and a body chassis.

[0009] Furthermore, CN 206 265 146 U shows an assembly of a commercial vehicle with a chassis frame and a driver's cab, consisting of a rear wall, a vehicle front section, a roof, side door frames and a floor structure component that is attached to the chassis frame.

[0010] Finally, from CN 205 916 215 U a driver's cab of a commercial vehicle is known which has a front component and a rear component as well as a floor structure component connecting them, which has a central engine tunnel.

[0011] The invention is therefore based on the objective of creating a body component for a driver's cabin of a motor vehicle and a motor vehicle with such a body component, wherein the aforementioned disadvantages are reduced, preferably do not occur.

[0012] The problem is solved by the features of claim 1 with regard to the body component and by the features of claim 12.

[0013] The problem is solved in particular by creating a body component for a driver's cab of a motor vehicle, especially a commercial vehicle, particularly a truck, which comprises a floor structure component, a front component, and a rear component. The floor structure component has a rear side, a front side opposite the rear side, particularly in a longitudinal direction, two sides, namely a first side (particularly the right) and a second side (particularly the left) opposite the first side, particularly in a transverse direction perpendicular to the longitudinal direction, as well as a bottom side and an upper side opposite the bottom side, particularly in a vertical direction perpendicular to both the longitudinal and transverse directions.The floor structure component has two inner longitudinal beams and two outer longitudinal beams, each oriented longitudinally. Specifically, the two inner longitudinal beams are arranged between the two outer longitudinal beams, particularly in the transverse direction. The two inner longitudinal beams are positioned above the two outer longitudinal beams, particularly in the vertical direction, and are spaced apart from them in the vertical direction. The floor structure component has a raised central section, particularly in the vertical direction, which forms a longitudinally oriented recess for the drive components. The raised central section is arranged transversely between the two inner longitudinal beams. The front component is connected to the floor structure component at its front face, particularly by welding, and extends vertically.The dismantling component is connected to the floor structure component on the back side of the component, in particular by welding, with the dismantling component extending particularly in the vertical direction.

[0014] Advantageously, the body component exhibits comparatively high mechanical strength due to its two internal longitudinal members, resulting in a driver's cab with such a component possessing comparatively high structural integrity. This reduces the risk of driver injury while simultaneously minimizing impact-induced compression of the cab. The forces introduced into the floor structure component during a frontal impact are advantageously transferred to the rear section by the two internal longitudinal members. The raised center section of the floor structure advantageously provides a larger, and in particular taller, space for the drive components, allowing the driver's cab to be lowered, especially by being mounted at a smaller vertical distance to the chassis, thus positioning the driver's cab lower relative to the road surface.This advantageously reduces the entry height into the driver's cab, resulting in a more comfortable entry situation. Furthermore, it reduces physical strain during driving tasks involving frequent entry and exit. The two inner longitudinal beams, positioned above the two outer longitudinal beams, effectively act as elevated force transmission paths – particularly load paths – transferring forces from the front component to the rear component.

[0015] In the context of this technical teaching, the fact that the two inner longitudinal members are arranged above the two outer longitudinal members means, in particular, that the two inner longitudinal members—when the body component is installed in a motor vehicle as intended—are arranged geodesically above the two outer longitudinal members. "Above" here means, in particular, that an inner longitudinal member plane spanned by the two inner longitudinal members, especially a horizontal plane, is arranged above, and in particular geodesically above, an outer longitudinal member plane spanned by the two outer longitudinal members, especially a horizontal plane. Thus, it is particularly possible that the two inner longitudinal members—viewed from the front of the body component—can be arranged obliquely inwards above, and between, the two outer longitudinal members, starting from the two outer longitudinal members.

[0016] In particular, the upper surface of the component – ​​when the body component is installed in a motor vehicle as intended – is geodesically positioned at the top, specifically above the lower surface of the component, while the lower surface of the component – ​​when the body component is installed in a motor vehicle as intended – is geodesically positioned at the bottom, specifically below the upper surface of the component. In particular, the front surface of the component – ​​when the body component is installed in a motor vehicle as intended – is positioned at the front in the straight-ahead direction of travel, specifically in front of the rear surface of the component, while the rear surface of the component – ​​when the body component is installed in a motor vehicle as intended – is positioned at the rear in the straight-ahead direction of travel, specifically behind the front surface of the component.

[0017] In the context of this technical teaching, "welded" means in particular welded by means of a process selected from a group consisting of: a spot welding process, a laser beam welding process, a metal active gas (MAG) welding process, a metal intergas (MIG) welding process and a tungsten intergas (TIG) welding process.

[0018] In one embodiment, the floor structure component is designed as a pressed component. In particular, the floor structure component is designed as a pressed steel sheet component.

[0019] In one embodiment, the front component and / or the rear component are designed as a pressed component. In particular, the front component and / or the rear component are designed as a sheet metal pressed component, especially a steel sheet metal pressed component or an aluminum sheet metal pressed component.

[0020] In one embodiment, the two inner longitudinal beams are oriented in the straight-ahead direction of travel of the motor vehicle when the body component is installed as intended in a motor vehicle.

[0021] In one embodiment, the two inner longitudinal beams are connected to the floor structure component, in particular by welding. In particular, the two outer longitudinal beams are connected to the floor structure component, in particular by welding.

[0022] In one embodiment, a first outer longitudinal member, particularly the right one, of the two outer longitudinal members is connected to the floor structure component on the first side of the component, in particular by welding. A second outer longitudinal member, particularly the left one, of the two outer longitudinal members is connected to the floor structure component on the second side of the component, in particular by welding.

[0023] In one embodiment, a longitudinal beam, selected from the two inner longitudinal beams and the two outer longitudinal beams, is designed as a hollow profile longitudinal beam. In particular, the selected longitudinal beam is manufactured using an internal high-pressure forming (IHPF) process. Specifically, a longitudinal beam, selected from the two inner longitudinal beams and the two outer longitudinal beams, has a closed profile, particularly with one or more chambers.

[0024] According to a further development of the invention, it is provided that the two inner longitudinal beams are each designed to be flat.

[0025] The flat design offers the advantage of reduced weight compared to uneven inner longitudinal beams. Furthermore, flat inner longitudinal beams are particularly easy to manufacture. They are also exceptionally rigid, which further improves the stability of the driver's cab.

[0026] In particular, the two inner longitudinal beams, especially their central axis – relative to a vertical direction – are completely flat, especially from the front component to the rear component. However, it is possible that the two inner longitudinal beams may have indentations and / or protrusions in certain areas.

[0027] In the context of this technical teaching, the fact that the two inner longitudinal members are flat means, in particular, that the two inner longitudinal members are not bent upwards or downwards when the body component is installed in a motor vehicle as intended. Specifically, one upper surface of each of the two inner longitudinal members is flat, and in particular, the upper surface of each of the two inner longitudinal members lies in a plane similar to an upper surface of the inner longitudinal member. Similarly, one lower surface of each of the two inner longitudinal members is flat, and in particular, lies in a plane similar to an lower surface of the inner longitudinal member.

[0028] According to a further development of the invention, the floor structure component comprises a first structural element, particularly on the right, a second structural element, particularly on the left, and a central structural element, particularly on the center, which includes the floor structure's central elevation. A first inner longitudinal member, particularly on the right, of the two inner longitudinal members is connected to the first structural element and the central structural element, particularly by welding. In particular, the first inner longitudinal member is arranged transversely between the first structural element and the central structural element. A second inner longitudinal member, particularly on the left, of the two inner longitudinal members is connected to the second structural element and the central structural element, particularly by welding.In particular, the second inner longitudinal beam is arranged in the transverse direction between the second structural component element and the structural center elevation element.

[0029] The floor structure component is advantageously designed in multiple parts, whereby the individual structural components are easier to manufacture and transport than the entire floor structure component.

[0030] According to a further development of the invention, the two inner longitudinal beams each have an inner longitudinal upper beam and an inner longitudinal lower beam. The inner longitudinal upper beam is arranged on the upper side of the component and connected to the floor structure component, in particular by welding. The inner longitudinal lower beam is arranged on the lower side of the component and connected to the floor structure component, in particular by welding.

[0031] In particular, the two inner longitudinal beams are each designed as double-shell structures, with the inner longitudinal upper beam forming an upper shell and the inner longitudinal lower beam forming a lower shell. Specifically, the inner longitudinal upper beam and / or the inner longitudinal lower beam are manufactured using a stretch bending process.

[0032] In particular, the multi-part floor structure component, which includes the first structural component element, the second structural component element and the structural center elevation element, has two internal longitudinal beams, each comprising the internal longitudinal upper beam and the internal longitudinal lower beam.

[0033] Advantageously, double-shell inner longitudinal beams exhibit higher mechanical strength and greater structural integrity than single-shell inner longitudinal beams. This further increases the stability of the body component and, consequently, the driver's cabin.

[0034] According to a further development of the invention, the two inner longitudinal beams are each attached at a front end to a central region of the front component, particularly with respect to the vertical direction, preferably by welding. The two inner longitudinal beams are each attached at a rear end opposite the front end to a lower region of the rear component, particularly with respect to the vertical direction, preferably by welding. This advantageously improves the force transmission from the front component to the two inner longitudinal beams and further to the rear component.

[0035] In the context of this technical teaching, a middle section of the front component is understood to be, in particular, the middle third of the component area of ​​the front component, relative to the vertical direction, when the front component is conceptually divided into three thirds of the component area arranged one above the other and of equal height. Specifically, the dividing planes between the three thirds of the component area run in the transverse direction.

[0036] In one embodiment, the two inner longitudinal beams are each attached at a front end to an upper area of ​​the front component, particularly with respect to the vertical direction, and in particular welded.

[0037] In the context of this technical teaching, an upper region of the front component is understood to mean, in particular, the upper third of the component area of ​​the front component in the vertical direction, if the front component is conceptually divided into three thirds of the component area arranged one above the other and of equal height. Specifically, the dividing planes between the three thirds of the component area run in the transverse direction.

[0038] According to a further development of the invention, the floor structure component is shaped such that it forms the two outer longitudinal beams. Alternatively or additionally, the floor structure component is shaped such that it forms the two inner longitudinal beams. This represents a particularly simple embodiment of the two inner longitudinal beams and / or the two outer longitudinal beams.

[0039] In one embodiment, the floor structure component is shaped on the first side of the component such that the floor structure component forms the first outer longitudinal beam of the two outer longitudinal beams on the first side of the component, wherein the floor structure component is shaped on the second side of the component such that the floor structure component forms the second outer longitudinal beam of the two outer longitudinal beams on the second side of the component.

[0040] According to a further development of the invention, the two inner longitudinal beams are each sectionally straight, particularly along the longitudinal direction. Straight inner longitudinal beams advantageously exhibit particularly high mechanical strength, especially dimensional stability.

[0041] The fact that the two inner longitudinal beams are each designed to be straight in sections means, in the context of the present technical teaching, in particular that the longitudinal beams are not bent to the right or left in sections - when the body component is installed in a motor vehicle as intended.

[0042] Alternatively or additionally, the two inner longitudinal beams are arranged parallel to each other in sections. This advantageously results in a uniform force distribution into the component being dismantled.

[0043] Alternatively or additionally, it is provided that the two inner longitudinal beams are designed to taper towards each other section by section, in particular such that the distance between the two inner longitudinal beams changes section by section along the longitudinal direction, in particular is reduced section by section.

[0044] In one embodiment, the two inner longitudinal beams each run straight and parallel to each other in a third section. In a second section adjoining the third section, the two inner longitudinal beams taper towards each other. In a first section adjoining the second section, the two inner longitudinal beams again run straight and parallel to each other. In particular, the first section adjoins the front component. In particular, the third section adjoins the rear component.

[0045] According to a further development of the invention, it is provided that an inner longitudinal member of the two inner longitudinal members has a molded section in which preferably an inner longitudinal member edge of the inner longitudinal member is chamfered, in particular has a chamfer.

[0046] The molded section is advantageously designed such that a seat, selected from a driver's seat and a passenger seat of the motor vehicle, can be partially arranged within the molded section, and in particular, can extend into the molded section. In this way, the selected seat can advantageously be mounted closer to the floor structure component in the driver's cabin than it would be without the molded section, thereby further lowering the head position and further improving visibility of the road.

[0047] In the context of this technical teaching, "chamfered" is understood in particular to mean that a single-mold profile cross-section of the inner longitudinal member in the mold section is reduced by a chamfer profile cross-section of the chamfer compared to a profile cross-section of the inner longitudinal member outside the mold section.

[0048] According to a further development of the invention, the raised center section of the floor structure is shaped such that it is arranged section by section, particularly in the vertical direction, above the two inner longitudinal beams. Advantageously, this further enlarges the space for the drive component, allowing the drive component – ​​when the body component is installed as intended in a motor vehicle – to extend further into the driver's cabin, thereby enabling the driver's cabin to be lowered further.

[0049] In the context of the present technical teaching, the fact that the floor structure center elevation is arranged above the two inner longitudinal beams means in particular that the floor structure center elevation – when the body component is installed in a motor vehicle as intended – is arranged geodesically above the two inner longitudinal beams, and in particular extends further geodesically upwards than the two inner longitudinal beams.

[0050] According to a further development of the invention, the floor structure component comprises a first structural component area and a second structural component area extending from the front of the component towards the rear. The first structural component area is arranged below the second structural component area, particularly in the vertical direction.

[0051] This design is advantageously adapted to the seating position of the driver and / or front passenger, as the footwell is positioned lower than the seating area. The stepped design also advantageously results in a further reduction in the entry height, making entry into the driver's cab more comfortable.

[0052] In one embodiment, the floor structure component has a third structural component area that connects to the second structural component area and is arranged above the second structural component area.

[0053] In one embodiment, a structural component element, selected from the first structural component element and the second structural component element, comprises the first structural component area, the second structural component area, and optionally the third structural component area.

[0054] According to a further development of the invention, the front component has transverse struts and vertical struts that connect the transverse struts to each other. The transverse struts and the vertical struts form at least two recesses.

[0055] In particular, the cross braces are oriented in the transverse direction. In particular, the vertical braces are oriented in the vertical direction.

[0056] In one embodiment, the front component has at least two cross members, one lower and one upper, and four vertical members forming four recesses: a right-hand first recess, a left-hand second recess, a middle upper third recess, and a middle lower fourth recess. In particular, the third and fourth recesses are separated from each other by a further middle third cross member. Specifically, the middle lower fourth recess is closed at the bottom, particularly by the lower cross member. In particular, the lower cross member acts as a reinforcing member, advantageously increasing the torsional stiffness of the front component.

[0057] In particular, the first recess is dimensioned such that electrical components can be attached, and in particular mounted, through the first recess. In particular, the second recess is dimensioned such that an accelerator pedal assembly can be attached, and in particular mounted, through the second recess. In particular, the third recess is designed for an air intake of an air conditioning system of the motor vehicle. In particular, the fourth recess is designed for an air intake for cooling a drive system of the motor vehicle.

[0058] In one embodiment, the floor structure component, the two inner longitudinal beams and / or the two outer longitudinal beams comprise or are formed from a material selected from a group consisting of: a steel material, a steel alloy, an aluminum material and an aluminum alloy.

[0059] The problem is also solved by creating a motor vehicle, in particular a commercial vehicle. The motor vehicle comprises a chassis, a drive component attached to the chassis, and a driver's cab, which includes a body component according to the invention or a body component according to one or more of the embodiments described above. The driver's cab and the drive component are attached to the chassis such that the drive component extends into a drive component receiving space formed by a raised section in the center of the floor structure of the body component. In connection with the motor vehicle, the advantages that have already been explained in connection with the body component become particularly apparent.

[0060] In particular, the drive component is a drive for propelling the motor vehicle, especially an internal combustion engine.

[0061] In particular, the driver's cab is arranged above, and especially geodesically above, the drive component. Specifically, the driver's cab is arranged on the motor vehicle in such a way that it can be folded open, especially forwards.

[0062] In particular, the motor vehicle is designed as a commercial vehicle, especially as a truck.
