Definitions
- the invention relates to a vehicle body made of a metallic material, in particular steel, with shell elements which are connected to one another and which are connected to one another, in particular a base plate and side walls with integrated side skirts, with one shell element protruding from the edge of the two shell elements facing the other shell element, which are inserted through through openings formed in the other shell element.
- Shell elements i.e. Application-specific shaped sheet metal elements, usually consisting of an interconnected upper and lower shell, fulfill the function of an enveloping wall and at the same time that of a load-bearing component.
- Vehicle bodies manufactured in this way are characterized by a low weight and by a significantly reduced number of parts compared to the space-frame construction based on profiles.
- a vehicle body is known from US Pat. No. 5,297,836 A, which is formed from joined, flat shell elements.
- a first shell element has protrusions.
- the second shell element to be joined with the first shell element has corresponding blind grooves.
- the protrusions of the first shell element are inserted into blind grooves in the second shell element and fastened there with the aid of adhesives.
- the first shell element is formed as a stiffening plate. It serves to increase the rigidity between a connection of two body panels.
- a weak point in the shell construction is the connection of the shell elements to one another.
- two shell elements for example the base plate of a vehicle body and the associated vehicle side wall, are connected to one another via bent edge regions which are formed on the base plate and which lie against the side wall and are integrally connected to it, as a rule by welding.
- this type of connection is easy to implement, it no longer offers a level of rigidity that meets today's requirements, since it depends to a large extent on the strength of the integral connection.
- a large number of additional reinforcement and stiffening sheets are required, which significantly increase the manufacturing effort.
- the invention is therefore based on the object of providing a vehicle body of the type mentioned at the outset with a high degree of rigidity which can be implemented without great manufacturing outlay.
- This object is achieved with a connecting knot of the type mentioned in the introduction that a sleeve, consisting of a sleeve section and a collar formed at one end, sits on the projections on both sides of the other shell element, and that the collar of the sleeve with the the area surrounding the push-through opening of the other shell element and the sleeve section are integrally connected to the overhang.
- the central advantage of this construction is that by pushing through the protrusions provided on one shell element through the push-through openings formed in the other shell element, the rigidity of a vehicle body formed from shell elements connected in this way is significantly greater compared to a vehicle body with shell elements connected exclusively by material connection.
- the usable connection zones for the cohesive seat of the cuffs are realized for a material connection of the interconnected shell elements.
- connection technology according to the invention for vehicle bodies in shell construction, in which several protrusions are inserted from the shell element through through openings formed in the side wall, the advantages of space frame technology with regard to body rigidity can be combined with the particular advantages of shell construction, namely the low weight and the greatly reduced number of parts, connect in an optimal way, so that the result is a body that is superior in all relevant characteristics to bodies of conventional design.
- connection nodes of comparable type are known from the prior art.
- the connection is not made by welding, but non-positively by a tool which is inserted into the end region of the cross member which is open at the end spreads the end region radially outwards and thus clamps it to the side member in the region of the opening.
- US Pat. No. 2,009,963 describes an essentially two-dimensional vehicle frame, consisting of two longitudinal members and different cross members.
- the cross members are cut at their ends crosswise, so that they form longitudinally aligned projections distributed over the circumference, the length of which slightly exceeds the wall thickness of the longitudinal members.
- the connecting nodes between the longitudinal and transverse beams are designed such that a transverse beam is inserted with its one end into an opening that is adapted to its circumference and is formed on the inside of the longitudinal beam so that the projections are aligned with the opening Molded slots are inserted on the outside of the side members and protrude slightly beyond the outside.
- the side member and the respective cross member are welded together on the protruding projections on the outside of the side member and in the region of the opening on the inside thereof.
- connection nodes of the cited publications have in common that they are only suitable for two- and three-dimensional vehicle support frames made of hollow profiles, in which a hollow profile is completely inserted with its end face into another or pushed through it.
- a simple transfer of the technical solutions shown to vehicle bodies in shell construction is therefore not possible, since they are flat, ie two-dimensional extensive, shell elements are based, so that simple plug-in solutions, as described in the aforementioned prior art, are not applicable.
- the push-through openings formed in the other shell element have an oversize relative to the dimensions of the protrusions of the one shell element.
- the base plate of a vehicle as a large-sized shell element, often has several, sometimes widely spaced, projections, by means of which it is connected to the vehicle side wall and, if appropriate, to further shell elements via the connecting knot according to the invention, which places particularly high demands on dimensionally stable production provides.
- larger manufacturing tolerances can thus be permitted.
- the integral connection is designed as a welded connection.
- the welded connection between the sleeve and the other shell element it is advantageous if it is designed as a laser weld seam. This results in an improved operational strength behavior of the construction and a higher rigidity. If this laser welding seam is also formed as a circumferential seam, a particularly tight connection between the sleeve and the other shell element can be achieved, which, for example, enables the Permeation of moisture at this point is minimized.
- Fig. 1 is a two-part base plate and a
- Fig. 2 shows the connection node between the base plate and side wall in a sectional view.
- the two-part base plate 1 according to FIG. 1 is designed in a shell construction made of metallic materials. Steel is particularly suitable as a metallic material, but also other materials, such as Aluminum.
- the base plate 1 consists of a rear part 10 and a front part 11, which are each composed of an upper shell lOo or llo and a lower shell lOu or llu.
- the gap remaining between the two parts 10, 11 is closed, for example, by a further shell element, not shown.
- a vehicle side wall 2 is also shown, one below the recesses for the
- the rear part 10 of the base plate 1 has two protrusions 10a extending in the direction of the rear of the vehicle and two protrusions 10b pointing outwards. Accordingly, the front part 11 of the base plate 1 has two protrusions 11c pointing in the direction of the vehicle front and two pairs of protrusions each pointing outwards 11a and 11b.
- three rectangular openings 20a, 21a, 21b are formed through the inner and outer shells 2i, 2a, through which the projections 10b, 11a, 11b of the rear and front part 10, pointing in the direction of the side wall 2, 11 of the base plate 1 can be inserted.
- the inner dimensions of the openings 20a, 21a, 21b are selected such that they have an oversize compared to the outer dimensions of the projections 10b, 11a, 11b assigned to them.
- FIG. 2 shows the connection nodes formed by the parts 10, 11 of the base plate 1 and the side wall 2 using the example of the protrusion 11b of the front part 11 of the base plate 1 and the opening 21b in the side sill 2s of the side wall 2.
- the protrusion 11b is pushed through the opening 21b in the side sill 2s. Since the inside dimensions of the opening 21b are designed with an oversize compared to the outside dimensions of the protrusion 11b, the upper and lower shells 11, 11 do not lie without gaps on the edges of the opening 21b, as can be seen in FIG. 2.
- the cuffs 3a and 3b continue to sit on the overhang 11b on both sides of the side wall 2.
- the collar 31a of the cuff 3a lies on the inner shell 2i and the collar 31b of the cuff 3b on the outer shell 2a.
- the protrusion 11b is preferably pushed so far through the opening 21b that the sleeve section 30b of the sleeve 3b is flush with the front edge of the protrusion 11b.
- the sleeves are integrally connected to the overhang 11b as well as to the side wall 2, preferably by means of a welded connection. According to FIG.
- the collars 31a, 31b of the sleeves 3a, 3b are connected to the side wall 2 by means of a laser weld 4b, and the sleeve sections 30a, 30b are connected to the overhang 11b via a spot weld connection 4a.
