Description

[0001] A holding arrangement for a battery in a vehicle, comprising a vehicle floor of a vehicle, a front axle frame and / or a rear axle frame and at least one battery. The holding arrangement further comprises at least one filler element, which is arranged at least partially between the front axle frame and the battery or between the rear axle frame and the battery, wherein the filler element bears at least partially with a first contact surface on the front axle frame or on the rear axle frame and with a second contact surface on the battery, and there is a continuous positive connection in the horizontal direction from the front axle frame or rear axle frame to the filler element and further to the battery. The invention further relates to a vehicle with a holding arrangement and to a method for mounting a battery on a vehicle.

[0002] In electrically powered vehicles, a battery is often attached beneath the vehicle floor. This attachment must be designed to secure the battery to the rest of the vehicle even in the event of an accident or crash. The front and rear axle supports are also attached to or beneath the vehicle floor. These axle supports can also be referred to as the front axle frame and rear axle frame. Typically, these axle frames and the battery are each connected separately to the vehicle floor. This connection is usually force-fit, for example via screw connections, in the vertical direction. The axle frame and the battery are each clamped to the vehicle floor with their own fastening elements. In order to be able to mount the components on the vehicle floor, gaps are provided between the components in the horizontal direction; these gaps are required for mounting the components.For example, the axle supports can be mounted on the vehicle floor first and then, in a subsequent step, the battery can be inserted between them and connected to the vehicle floor. In this case, gaps are provided between the battery and the front axle frame and between the battery and the rear axle frame to allow the battery to be installed, also known as retracting. These gaps between the components are also present when the vehicle is assembled. If batteries of different sizes are to be used for the same vehicle type or if one battery type is to be used in vehicles of different sizes, the distances between the battery and the axle supports below the vehicle will vary. In the event of an accident or crash, the heavy battery will generate inertial forces which act in a horizontal direction and load the attachment to the vehicle floor.For this reason, the fastening elements used to secure the battery to the vehicle floor must be large, or a large number of smaller fastening elements must be provided. The type and number of fastening elements depend on the type and actual weight of the battery used. Furthermore, an accident also generates horizontal forces that strain the connection between the axle frame and the vehicle floor.

[0003] CN218519525U describes mounting components that are connected, on the one hand, to a longitudinal member on the vehicle floor and, on the other hand, to a battery located underneath the vehicle. These mounting components can be arranged at various positions underneath the vehicle and can be easily adapted in size and / or position to different types of batteries.

[0004] DE102010035367B4 describes a crash-absorbing assembly for a motor vehicle. The assembly is arranged between the outer skin of the vehicle and a battery and includes a deformation element that supports the forces occurring during a crash against the battery. To evenly distribute locally occurring force peaks across the battery, the assembly includes a shield-shaped force distributor that evenly distributes the forces across the deformation element during a crash.

[0005] DE102019207450A1 describes a vehicle battery with a modular design. The vehicle battery comprises a housing with several compartments that can be equipped with battery cells as needed. For compartments that do not contain battery cells, a stiffening element is proposed that has similar mechanical properties to battery cells. In this way, the mechanical properties of the entire battery or battery housing remain constant, even if not all compartments in the battery housing are equipped with battery cells.

[0006] The object of the invention is to propose solutions with which a secure fastening of a battery to a vehicle floor can be improved, whereby this fastening of the battery should also be able to withstand an accident of the vehicle.

[0007] This object of the invention is achieved by a holding arrangement for a battery in a vehicle, comprising - a vehicle floor of a vehicle, which carries the remaining components of the holding arrangement, - a front axle frame which supports the front axle of the vehicle and / or a rear axle frame which supports the rear axle of the vehicle, - at least one battery, which is intended in particular as a drive battery for driving the vehicle, - at least one filling element, which is arranged at least partially between the front axle frame and the battery or between the rear axle frame and the battery, wherein the front axle frame and / or the rear axle frame and the battery are each arranged below the vehicle floor and connected thereto, wherein the filling element rests at least partially with a first contact surface on the front axle frame or on the rear axle frame and with a second contact surface on the battery, wherein the first contact surface and the second contact surface are arranged opposite one another in the horizontal direction on the filling element,wherein the filling element is connected to the front axle frame or rear axle frame and the battery and / or the vehicle floor and there is a continuous form fit in the horizontal direction from the front axle frame or rear axle frame to the filling element and further to the battery and the filling element bridges a distance in the horizontal direction between the front axle frame or rear axle frame and the battery, in particular without play.

[0008] The holding arrangement according to the invention serves to fasten a battery in or on a vehicle. In the following, the term "battery" refers to the entire assembly comprising a plurality of battery cells, their electrical wiring, and a battery housing. The connection points of the battery to the other parts, such as the vehicle floor, are preferably arranged on the battery housing of the battery. The term "vehicle" is preferably understood to mean a motor vehicle that is electrically driven, with the battery being provided as the drive battery. The terms "front axle frame" and "rear axle frame" are understood to mean the assemblies that connect the front axle and the rear axle, respectively, to the rest of the vehicle and that hold and guide the axles during vehicle operation.

[0009] The holding arrangement according to the invention comprises a vehicle floor, which can include, for example, longitudinal and cross members as well as body panels and other components. All other components of the holding arrangement are fastened to the vehicle floor. The holding arrangement includes at least one front axle frame or one rear axle frame. Both axle frames are usually provided on a vehicle, one or both of which can belong to the holding arrangement according to the invention. The holding arrangement also comprises a battery, which is preferably arranged horizontally between the front axle frame and the rear axle frame. The battery can have different dimensions. In the mounted state on the vehicle, a distance is provided between the front axle frame and the battery, and between the battery and the rear axle frame, which distance is required to install or remove the battery.If batteries with different horizontal dimensions are installed for a vehicle type, the distances between the battery and the axle frame vary. The horizontal distances between the battery and the axle frame remain the same when the vehicle is assembled. According to the invention, the holding arrangement further includes at least one filler element which is arranged at least partially at a distance between the front axle frame and the battery or between the rear axle frame and the battery. This filler element bridges the distance between these components and creates a continuous positive connection from the axle frame to the battery. This continuous positive connection is preferably free of play, which also creates a continuous flow of force from the axle frame via the filler element to the battery. The filler element comprises a first contact surface and a second contact surface which are located opposite one another in the horizontal direction on the filler element.When the holding arrangement is assembled, the first contact surface rests against an axle frame and the second contact surface rests against the battery. The filler element is clamped against the vehicle floor from below and is either attached to the vehicle floor together with an axle frame and the battery or connected to the vehicle floor via separate, additional connecting elements. The filler element bridges the distance between an axle frame and the battery required for the battery to be installed. The filler element is designed to be pressure-resistant and rigid in the horizontal direction. The filler element can be made of an iron-based material and can be designed, for example, as a sheet steel part. Alternatively, the filler element can be designed as an aluminum die-cast component, which in particular has ribs for reinforcement.The holding arrangement according to the invention creates a continuous form-fit connection in the horizontal direction beneath the vehicle floor, which forms a continuous force path from at least one axle frame via the filler element to the battery and vice versa. If there is a gap between the battery and the front axle frame or between the battery and the rear axle frame, at least one filler element is inserted into both of these gaps. In this case, a continuous force path is created from the front axle frame via a first filler element to the battery and via a second filler element to the rear axle frame. In the event of an accident, forces acting in the horizontal direction are transmitted via this continuous force path and thus distributed to all components fastened beneath the vehicle floor. In this way, the accident-related forces are transmitted into the vehicle floor via the fastenings of all these components.This reduces the load on each of these individual fastenings compared to a case in which there is no continuous force path between the components under the vehicle floor and accident-related forces have to be diverted into the vehicle floor by fastening only one of these components. The holding arrangement according to the invention thus improves the fastening of a battery to a vehicle floor in that the loads on the battery fastening that occur during an accident are also transferred to the fastening of at least one axle frame. The accident-related loads or forces are thus distributed in a form-fitting manner across several fastenings on the vehicle floor. The individual fastenings are therefore subjected to less load and can therefore be dimensioned smaller than in a case in which no holding arrangement according to the invention is provided.The advantage of the mounting assembly is that it can be easily attached to the vehicle floor. Furthermore, the mounting assembly can be reinstalled and reused even if the battery is replaced. The shape of the filler element is not limited to a location between the axle frame and the battery. Rather, the filler element can also extend further horizontally beneath the other components and be connected to these components at other points, either force-fitting or form-fitting. These additional connection points can further improve the transmission of forces in the event of an accident.When installed below the portion of the filler element where the two contact surfaces are located, the filler element can be designed, for example, as a shear panel or a crash tab, which transmits accident-related forces and / or moments between the components below the vehicle floor in a force-locking manner. The holding arrangement according to the invention is particularly advantageous for vehicle platforms where the distances between the battery and the axle frame vary depending on the installed components. Filler elements of different sizes can be easily provided and kept ready, adapted to the different distances between the components below the vehicle.For example, batteries with different horizontal dimensions can be easily and safely installed in a vehicle type with constant horizontal dimensions, while always maintaining a continuous force path between the components under the vehicle floor. Alternatively, it is conceivable to design a filler element that is length-adjustable or telescopic, allowing it to be individually adapted to the prevailing distance between an axle frame and the battery.

[0010] In one embodiment, the filler element is inserted with an interference fit in the horizontal direction between the front axle frame or the rear axle frame and the battery, and the first contact surface and / or the second contact surface are plastically and / or elastically deformed at least in some regions relative to their shape before installation of the filler element. In this embodiment, the filler element is deformed during assembly so that it bridges the distance between an axle frame and the battery in the horizontal direction without play. For this purpose, the filler element is designed with an interference fit. This means that the dimensions of a partial area of ​​the filler element before assembly are larger than the distance between the components between which the filler element is inserted.When joining or assembling the filling element, the first contact surface and / or the second contact surface is deformed so that in the assembled state it is deformed relative to its unassembled state.

[0011] In a further embodiment, it is provided that the filler element is made of a metal at least in part and the first contact surface and / or the second contact surface is arranged on at least one tolerance rib which points towards the front axle frame, the rear axle frame or the battery, wherein the tolerance rib is plastically deformed at least in part relative to its shape prior to assembly of the filler element by the installation of the filler element between the front axle frame or the rear axle frame and the battery. A tolerance rib is understood to be a partial area which protrudes beyond the adjacent partial areas of the filler element and which has dimensions in the horizontal direction which result in an interference fit with the distance between an axle frame and the battery. Such a tolerance rib is the partial area of ​​the filler element which is deliberately deformed during joining or assembly.The width of such a tolerance rib is designed so that it is deformed horizontally during assembly in the vertical direction. Preferably, several tolerance ribs are provided for both the first contact surface and the second contact surface. The tolerance rib is formed from a ductile material, in particular a metal, which allows plastic deformation during joining without damaging or destroying the filler element. Other subregions of the filler element that are not part of the tolerance rib can also be made of a brittle material, since formability is not required in these other subregions.

[0012] In one embodiment, it is provided that the tolerance rib is wedge-shaped at least in some areas, wherein the wedge-shaped area extends in the vertical direction, wherein the wide side of the wedge-shaped area is arranged at the bottom and the narrower side of the wedge-shaped area is arranged at the top and the distance in the horizontal direction between the narrower side of the wedge-shaped area and the opposite contact surface is smaller than the clear width between the front axle frame or the rear axle frame and the battery and the distance in the horizontal direction between the wider side of the wedge-shaped area and the opposite contact surface is the same size or greater than the clear width between the front axle frame or the rear axle frame and the battery.A wedge-shaped design of the tolerance rib ensures that a vertically directed force applied to join the filler element between the other components is translated into a horizontally directed force, which deforms the tolerance rib during joining. The wedge-shaped area is aligned vertically, with the wider side at the bottom and the narrower side at the top. This allows the filler element to be inserted into the gap between the axle frame and the battery with the narrower side of the wedge-shaped area first. As the filler element moves into the gap, the wedge-shaped area then rests against the other components and is deformed during further movement in the vertical direction.

[0013] In a further embodiment, it is provided that the front axle frame and / or the rear axle frame and the battery are connected to the vehicle floor by fastening elements, wherein these fastening elements provide a force-locking connection in the vertical direction, in particular wherein the fastening elements are designed as vertically oriented screw connections, wherein the filling element is connected to the front axle frame and / or the rear axle frame, the battery and / or the vehicle floor by the same fastening elements or the filling element is clamped in the vertical direction to the front axle frame or the rear axle frame, the battery or the vehicle floor by separate additional fastening elements. In one embodiment, an axle frame, the battery and the filling element are connected to the vehicle floor by common fastening elements.The fastening elements clamp the components vertically against the vehicle floor, creating a horizontal frictional connection between the components and the vehicle floor. Preferably, several screw connections are used as fastening elements. Alternatively, an axle frame and the battery can initially be clamped to the vehicle floor with fastening elements without the filler element. In a second step, the filler element is then inserted between the other components and clamped vertically to the vehicle floor with additional or separate fastening elements.

[0014] In one embodiment, a vertical gap exists between the vehicle floor and the filler element, which is partially bounded horizontally by the front axle frame or the rear axle frame and the battery. The gap serves as a guide channel for connections or cables. The gap is created by making the vertical dimension of the filler element smaller than the vertical dimensions of the axle frame and battery. The gap can be used to arrange various elements under the vehicle floor.

[0015] In a further embodiment, it is provided that the filling element has a filling region on which the first contact surface and the second contact surface are arranged opposite one another in the horizontal direction and the filling element further has two fastening regions, one of which projects horizontally beyond a contact surface and wherein the filling region is arranged between the two fastening regions and one fastening region is arranged vertically below the front axle frame or the rear axle frame and the battery and rests thereon, in particular wherein the two fastening regions are arranged spaced apart from one another in the vertical direction. In this embodiment, the filling element comprises several sub-regions which fulfil different functions.The dimensions of the filling area, particularly the distance between the two contact surfaces, are adapted to the distance between an axle frame and the battery. The mounting areas are arranged and designed so that they can be easily used to attach the filling element to an axle frame and the battery. The mounting areas are preferably plate-shaped.

[0016] In one embodiment, at least one filler element is arranged horizontally between the front axle frame and the battery, and between the rear axle frame and the battery. In this embodiment, the holding arrangement comprises at least two filler elements, one of which is arranged between the front axle frame and the battery, and another between the rear axle frame and the battery. This embodiment is particularly advantageous when the horizontal dimension of the battery is significantly smaller than the distance in the horizontal direction between the front axle frame and the rear axle frame.

[0017] The object of the invention is further achieved by a vehicle with a holding arrangement according to one of the previously described embodiments, in particular wherein the vehicle is designed as an electrically driven vehicle and the battery as a drive battery. The vehicle according to the invention comprises at least one holding arrangement for fastening a battery on or under the vehicle floor. The vehicle is preferably an electrically driven vehicle, wherein the battery is used as a drive battery for the electric drive. By arranging the battery using a holding arrangement, the battery is securely located beneath the vehicle floor and, by providing a closed force path, enables the transmission of forces that may arise in the event of an accident involving the vehicle. At the same time, the battery is easily accessible and can be easily removed from the vehicle or replaced.

[0018] The object of the invention is finally achieved by a method for mounting a battery on a vehicle, wherein a holding arrangement according to one of the previously described embodiments is used to carry out the method, comprising the method steps A) Positioning of the front axle frame, the rear axle frame and the battery relative to the vehicle floor so that the front axle frame, the rear axle frame and the battery rest vertically on the vehicle floor, B) partial insertion of at least one filling element between the front axle frame and the battery or the rear axle frame and the battery, C) Bracing the filling element in a vertical direction relative to the vehicle floor, wherein the first contact surface rests on the front axle frame or the rear axle frame and the second contact surface rests on the battery, wherein the first contact surface and / or the second contact surface is plastically and / or elastically deformed during the bracing and a continuous form fit is created in the horizontal direction from the front axle frame or rear axle frame to the filling element and further to the battery, wherein in method step A) the front axle frame, the rear axle frame and the battery are connected separately to the vehicle floor and the filling element is fastened to the other components in method step C) or in method step C) the front axle frame, the rear axle frame, the battery and the filling element are fastened together to the vehicle floor.

[0019] The method according to the invention serves for the simple and secure installation and fastening of a battery to a vehicle. A holding arrangement according to the invention is used in the method. The method is preferably carried out in the described order of method steps A) to C). At the beginning of the method, a vehicle with a vehicle floor and at least one axle frame, a battery, and a filling element are provided.

[0020] In a first process step A), a front axle frame and / or a rear axle frame, as well as the battery, are positioned horizontally relative to the vehicle floor and moved vertically from below to the vehicle floor. The first process step serves to position the components relative to each other so that they can be secured using fasteners in the next step.

[0021] In a second process step B), a filler element is inserted into the gap between a front axle frame and the battery or between a rear axle frame and the battery, at least in part. The inserted portion of the filler element is intended to fill the gap between the other components in a form-fitting and play-free manner after completion of the process.

[0022] In a third process step C), the filler element is moved vertically upward toward the vehicle floor and clamped against the vehicle floor. The first contact surface rests against the axle frame, and the second contact surface rests against the battery. During the clamping process step, at least one of the two contact surfaces is plastically and / or elastically deformed to fit the filler element between the other components without any play.

[0023] According to the method according to the invention, the components can be attached to the vehicle floor in two different ways: in method step A), it is possible to initially connect one or both axle frames and the battery separately to the vehicle floor, in particular via connecting elements. The filler element is then only connected to the vehicle floor and / or an axle frame and / or the battery in method step C), independently of the other components. This option has the advantage that the installation of the filler element is easier because the other components are already attached to the vehicle floor. Alternatively, it is possible to connect all components together to the vehicle floor only in method step C). With this option, the same connecting elements and connection interfaces on the vehicle floor can be used for all components.The advantage of this option is that only a single process step is required to attach all components to the vehicle floor at the same time.

[0024] The method according to the invention is simple to implement and results in the secure attachment of a battery to a vehicle. The method can be easily adapted to different vehicle types and / or battery dimensions by simply using differently dimensioned filler elements for the attachment. The method is therefore particularly suitable for attaching batteries to different vehicle types on a vehicle platform.

[0025] Features, effects, and advantages disclosed in connection with the holding arrangement are also deemed to be disclosed in connection with the vehicle and the method. The same applies in reverse: features, effects, and advantages disclosed in connection with the vehicle and / or the method are also deemed to be disclosed in connection with the holding arrangement.

[0026] The invention is schematically illustrated by means of embodiments in the drawings and will be further described with reference to the drawings. They show: Fig. 1 shows a schematic side view of a holding arrangement according to a first embodiment of the invention, Fig. 2 shows a schematic side view of a holding arrangement according to a second embodiment of the invention, Fig. 3 shows a schematic side view of an enlarged portion of the holding arrangement from Fig. 1.

[0027] Fig. 1 shows a schematic side view of a holding arrangement 1 according to a first embodiment of the invention. The components of the holding arrangement 1 are shown in a simplified manner. At the very top, the vehicle floor 11 can be seen, which is symbolized here by a U-shaped body panel. The vehicle floor 11 can of course comprise further components, such as longitudinal or cross members. On the left-hand side, symbolized by a block, the front axle frame 12 can be seen, which rests vertically on the vehicle floor 11. On the right-hand side, also symbolized as a block, a rear axle frame 13 is arranged, which also rests on the vehicle floor 11. A battery B is arranged horizontally between the front axle frame 12 and the rear axle frame 13 and rests vertically on the vehicle floor 11.In the illustrated embodiment, there is no horizontal distance between the rear axle frame 13 and the battery B; both components rest against each other horizontally. On the left-hand side, however, there is a horizontal distance between the front axle frame 12 and the battery B. The filler element 14 is partially inserted into this distance and, in the assembled state shown, bridges the distance between the front axle frame 12 and the battery B without play. The filler element 14 comprises a first contact surface 141, which in the illustrated embodiment faces horizontally to the left, towards the front axle frame 12. This first contact surface 141 rests directly against an outer surface of the front axle frame 12. The filler element 14 further comprises a second contact surface 142, which lies horizontally opposite the first contact surface 141 and rests against an outer surface of the battery B.In the illustrated embodiment, the filling element 14, together with the front axle frame 12 and the battery B, is connected in a force-fitting manner in the vertical direction to the vehicle floor 11 via a fastening element 15. The fastening elements 15 are designed here as screw connections which clamp the components in the vertical direction from bottom to top to the vehicle floor 11. Fig. 1, the front axle frame 12 and the battery B are first aligned horizontally with the vehicle floor 11 and brought into contact with it vertically. Subsequently, the filling element 14 is introduced vertically into the space between the front axle frame 12 and the battery B and is clamped against the vehicle floor 11 together with the other components via at least one fastening element 15. During this clamping of the filling element 14 against the vehicle floor 11, at least a partial area of ​​the first contact surface 141 and / or the second contact surface 142 is plastically and / or elastically deformed in order to create a play-free positive connection in the horizontal direction. Details of this deformation of the contact surfaces 141, 142 are described in connection with Fig. 3. In the illustrated embodiment, a vertical gap Z exists between the vehicle floor 11 and the filler element 14. This gap is bounded on the right and left by the front axle frame 12 and the battery B, respectively. In the illustrated embodiment, the gap Z extends into the plane of the drawing and can be used as a guide channel for connections, cables, or lines. The gap Z is protected and arranged between the other components, thus enabling the safe laying of installation lines, power cables, data cables, or other components beneath the vehicle floor 11.

[0028] Fig. 2 shows a schematic side view of a holding arrangement 1 according to a second embodiment of the invention. Fig. The second embodiment of a holding arrangement 1 shown in Figure 2 comprises two filling elements 14, which lie horizontally on two opposite sides of the battery B. On the left side, a filling element 14 is arranged and fastened in the same way as in the first embodiment in Fig. 1. On the right-hand side, between the battery B and the rear axle frame 13, a second filler element 14 is arranged. This second filler element 14 rests with a first contact surface 141 on the rear axle frame 13 and with a second contact surface 142 on the battery B without any play. The two filler elements 14 thus bridge both the distance between the front axle frame 12 and the battery B and the distance between the battery B and the rear axle frame 13. In the second embodiment, there is therefore a continuous positive connection in the horizontal direction from the front axle frame 12 to the rear axle frame 13. There is therefore a continuous force path or force connection in the horizontal direction, whereby forces and moments occurring in the event of an accident are passed on from one component to the next.In this way, the load is distributed among the individual fastening elements 15, whereby each of these fastening elements 15 is subjected to less load than in an arrangement which does not have filling elements 14. In the cases shown in . Fig. 1 and Fig. In the two embodiments shown in Figure 2, the vehicle floor 11, the front axle frame 12 and the rear axle frame 13 are identical and positioned in the same way relative to each other. Only the battery B is in the Fig. 2 is smaller in the horizontal direction than in the first embodiment in Fig. 1. Such a difference can occur, for example, if different batteries B are available or offered for a vehicle type. With a holding arrangement 1 according to the invention, such a difference in the size of the battery B can be very easily compensated for by providing a second filler element 14. For both battery sizes, it is ensured that the battery B is securely fastened below the vehicle floor 11 and that forces occurring in the event of an accident are distributed across all components arranged below the vehicle floor 11.

[0029] Fig. 3 shows a schematic side view of an enlarged portion of the holding arrangement 1 from Fig. 1. In Fig. 3 is a subsection of Fig. 1 is an enlarged view showing the filler element 14 and the sub-regions of the other components arranged adjacent thereto. In the embodiment shown, the filler element 14 comprises three sub-regions: on the far left is a fastening region 144, which is provided for fastening the filler element 14 to the front axle frame 12 and the vehicle floor 11; to the right of this is a filler region 143, which is inserted into the space between the front axle frame 12 and the battery B and which comprises the two contact surfaces 141 and 142; on the far right is a further fastening region 144, which is provided for fastening the filler element 14 to the battery B and the vehicle floor 11. The two fastening regions 144 protrude horizontally beyond the filler region 143 and bear vertically against the front axle frame 12 and the battery B, respectively.The fastening elements 15 are each guided through a fastening region 144. Since, in the illustrated embodiment, the front axle frame 12 has smaller dimensions in the vertical direction than the battery B, the two fastening regions 144 are offset or spaced from one another in the vertical direction. In the illustrated embodiment, the width of the filling region 143 between the two contact surfaces 141, 142, when the filling element 14 is not mounted, is greater than the distance between the front axle frame 12 and the battery B. When the filling element 14 is inserted into this distance in the vertical direction, at least one of the two contact surfaces 141 and 142 is plastically and / or elastically deformed so that the filling region 143 fits into the distance between the front axle frame 12 and the battery B.Due to the interference fit when joining the filler element 14, a portion of the filler element 14 is deformed in the horizontal direction, thereby ensuring a play-free positive connection in the horizontal direction between the three components. This deformation of a portion of the filler element 14 also makes it possible to compensate for tolerances in the distance between the front axle frame 12 and the battery B. In the embodiment shown, the filler element 14 has at least one tolerance rib R on its filler area 143, which points towards the front axle frame 12 and the battery B, respectively. The first contact surface 141 and the second contact surface 142 are each arranged on an outward-facing side of a tolerance rib R. The tolerance ribs R are each wedge-shaped and extend upwards in the vertical direction, starting from a respective fastening area 144.The wider side of the wedge-shaped area is at the bottom, and the narrower side of the wedge-shaped area is at the top. The two contact surfaces 141, 142 are arranged on the end faces of the wedge-shaped areas and thus, when the filler element 14 is not yet installed, run at an angle to the vertical. As can be clearly seen in the illustration, the distance between the narrower side of the wedge-shaped area and the opposite contact surface 141 or 142 is smaller than the distance or the clear width between the front axle frame 12 and the battery B. In contrast, the distance between the wider side of the wedge-shaped area and the opposite contact surface 141 or 142 is wider than the clear width between the front axle frame 12 and the battery B when the filler element 14 is not installed.This area, which is wider than the distance between the front axle frame 12 and the battery B, is deformed when the filler element 14 is joined or installed, whereby the contact surfaces 141 and 142 resting on the adjacent components are reshaped. Due to the wedge shape and the resulting translation of the vertical joining movement into a horizontally directed force, which reshapes the contact surfaces 141 and 142, a perfect fit of the filler area between the front axle frame 12 and battery B can be achieved in a simple manner. This fitting in the horizontal direction occurs automatically through the vertical assembly of the components front axle frame 12, filler element 14, and battery B. The process for installing the battery B on the vehicle can thus be carried out simply and quickly, since no separate process step for adjusting the filler element 14 between the front axle frame 12 and battery B is required.The relationships described above also apply analogously to the installation or fitting of the . Fig. 2, which is arranged between the battery B and the rear axle frame 13.
