Definitions
- sill as a body element absorbs both frontal collisions and side impact loads. In side impact, a balanced stiffness is desired, which allows a targeted reduction of the impact energy. So are multi-part sills with closed professional! often provided in their interior with ribs, stiffeners or generally load transfer elements, in particular to selectively increase the buckling resistance, as disclosed for example in DE 1 1 2008 002 515 T5.
- the rocker geometry is important insofar as it specifies how, in particular from which direction and in which production step, the insertion of load transfer elements has to be made.
- a disadvantage " is that the forms of load transfer elements and surrounding deformation contour of the sill are usually designed so that the deformation contour of the sill must be closed before the usual coating by means of cathodic dip painting (because of the focus static and dynamic requirements It is not possible to insert load-transfer elements after dip-coating without having to incur undesirable disadvantages during the entire production process, which limits the choice of material for the load-transfer elements Moldings contribute significantly to weight and material use in bodywork.
- CONFIRMATION COPY It therefore raises the task to achieve a weight reduction while saving material to increase the possibilities in the selection of materials, as well as a mixture of materials such as steel and aluminum, so to allow a hybrid design, the disadvantages listed eliminate and improve the interaction of the wearer and sills.
- acinaschweiler fulfills the classic function of a sill, so the targeted load absorption in frontal or side impact events, and on the other hand, the function of a rohbaufesten carrier in the overall structure of a vehicle body, preferably as a longitudinal beam of a mounting frame for a body.
- the two functions are brought together by an already rohbaufest installed molding of the body support, which alone does not have sufficient load capacity and resilience, as a support element together with the rest of the bodyshell, preferably after the anti-corrosion treatment by cathodic dip painting (KTL), with a rocker element is joined together.
- KTL cathodic dip painting
- the sill element increases on the one hand the carrying capacity and load capacity of rohbaufesten support member to the extent sufficient for a body support and thus constituted, together with the support member, an at least two-part body support, on the other hand has the properties for absorbing impact loads that are required for a whoschweiler ,
- the proportion of the carrier element in relation to the proportion of the rocker element on the body carrier or safety pawl can be adapted to the respective requirements.
- the support element is installed rohbaufest.
- the sill element is made rohbau turc and with a support element, which is for example part of a mounting frame, joined together.
- the cross section of the carrier element is L-shaped 'and is disposed within the bodyshell such that the side legs of the L along the Y-axis If the sill element also has an L-shaped cross-section, which in terms of its size a The sill element can advantageously complement the carrier element to form a closed, rectangular body carrier or safety hoarder.
- embodiments with different load-bearing elements can be provided, which are adapted to the respective requirements for the properties with respect to the absorption of impact energy, for example as a honeycomb structure, and are enclosed by the carrier and sill element formed, closed in cross section deformation contour, but otherwise are not subject to limitation in their nature and structure by the process of cathodic dip coating or other suitable type of coating.
- the safety rocker has a support member with a cavity on the outside, in 'the rocker element can be inserted form-fit laterally, substantially along the Y-axis.
- the carrier element has the shape of a horizontal U, the opening facing outward and forms the cavity for the sill element. It is advantageous for the lateral accessibility of the cavity, when the cross-section is opened to the side in such a way that the tangents of the outermost points of the drawn as a simple line contour on the inside or run parallel.
- the term tangent refers not only to the slope in a point of a curved line but also in a point of a straight line.
- connection technique that does not require the use of heat or heat as in welding techniques. It is therefore preferred a connection of support element and sill element by means of gluing or screws.
- all contact surfaces of the positive connection between the two mold parts have an inclination relative to the XY plane of the body, since the frictional engagement on parallel to the X-Y plane extending contact surfaces also adhesive reinforced significantly in the event of side impact loads less than correspondingly inclined surfaces.
- additional moldings must be used here.
- contour the sill element so that it not only completely or partially fills the cavity of the carrier element after being joined to the carrier element, but also has a shape outside this cavity which corresponds in function and extent to an additional crash molded part.
- Advantage of the multi-unit construction with crash molding is that prefabricated moldings of different materials can be used, which optionally include a respective specific load transfer element that can be optimally adapted to the stress of the molding in its respective position.
- a mix of materials with respect to the safety tiller is possible regardless of an additional crash molding, for example, if the support member made of steel and the sill member is made of aluminum. Also, a combination of different structures and materials for a combined load transfer element within a closed cross-section, such as that of the rocker element or the safety pylon composed of L-shaped support and rocker element, is possible.
- the load transfer elements now a variety of materials in question, such as composites, aluminum foam as cavity filling, ribs or the like, honeycomb structures or any combination of these. Due to the production engineering possibilities, which opens the joining of a support member with a rocker element to abutschweiler, materials can now be used for the load transfer elements, which could not be used due to the physical conditions during the previously necessary after installation of load transfer elements painting step. If desired, the mountable sill element can of course be subsequently provided with a suitable coating, or the externally visible part of the deformation contour are covered with a design panel having the desired optical properties.
- a preferred embodiment of the safety spring for electric vehicles results when the mountable carrier element is part of a, conveniently closed mounting frame for the body, which has a receptacle for a battery pack.
- the L-shape of the support element is used, which is complemented by a complementary L-shaped rocker element.
- the joining of carrier and sill member at least partially along the Z-axis.
- Fig. 1 shows a cross section through acinaschweiler (1), which is assembled from a rohbaufesten carrier element (2) and a mountable sill element (3) by gluing. Shown here are inner (5) and outer side (6) of the support element (2), wherein the outer side (6) in this embodiment has a nearly U-shaped cavity (see Fig. 2, item 7).
- a body support (4) is constituted, which coincides with theprofileschweiler (1), wherein the supporting properties in this example predominantly from the support element (2) and the cavity (see Fig. 2, item 7) filling part of the sill element (3) result.
- the outer circumferential surface of the safety tinder forms the deformation contour (20), which can also be covered with an optionally attachable design panel.
- Fig. 2 shows the carrier element (2) with attached B-pillar in cross-section and the matching rocker element (3) in cross section.
- Fig. 2 shows the rocker element (3) in cross section as a one-piece embodiment with an advantageous shape.
- the contact surfaces (18) for the positive connection between the carrier element (2) and rocker element (3) are shown, which are advantageous here all inclined relative to the X-Y plane of the body and thus provide a good frictional engagement in the event of impact loads.
- FIG. 3 shows another embodiment of the safety spring (1) in cross section, which is particularly suitable for electric vehicles due to the L-shape of the shell-side sill element (3) and the complementary L-shape of the support element (2), wherein the Carrier element (2) via connecting extensions (8) with the rocker element (3) is connected, here by means sketched by broken lines screw. Furthermore, here already part of the mounting frame (25) with receptacle (26) for a battery pack (27) for an electric vehicle can be seen.
- Fig. 4 shows the carrier element (2) and the sill element (3) prior to assembly of the embodiment of Fig. 3 in cross section.
- a load transfer element (22) can be inserted easily between the carrier (2) and sill element (3).
- the attached B-pillar is also indicated here in the position of the bodywork Automation Modell.
- Fig. 5 shows the mounting frame (25) with the carrier element (2) and the sill element (3) from the side in cross section along the X-Z plane for the embodiment of FIG. 3rd
