fig1 a to 1c show various views of a support structure 1 according to an embodiment of the invention , fig1 a shows a perspective view of the support structure , fig1 b a view of the support structure seen from above , and fig1 c a section along the line 1 c - 1 c shown in fig1 b . the support structure 1 is an axle support or auxiliary frame for a motor vehicle . in the embodiment shown here the support structure 1 is in the form of a two - shell structure with an upper shell 2 and a lower shell 3 ( see in particular fig1 c ), the shells being firmly joined to one another to form a frame element 7 . the upper shell 2 and the lower shell 3 are in each case s - shaped ( in this case shown as back - to - front mirror images ), so that the upper shell 2 can be joined to the lower shell 3 along their respective , substantially straight upper and lower surfaces 4 , 4 ′, 5 , 5 ′, for example by bonding . between the upper shell 2 and the lower shell 3 a hollow space 6 is formed , which however , can also be filled with a low - density material as already described earlier . the wall thickness of the upper and lower shells 2 , 3 is 4 to 5 mm . the frame element 7 is made of a fiber - reinforced plastic and has a substantially rectangular shape with four corner sections 8 , 8 ′, 8 ″, 8 ′″, such that from each corner section 8 , 8 ′, 8 ″, 8 ′″ an elastic connection point 9 , 9 ′, 9 ″, 9 ′″ projects in the direction transverse to the longitudinal axis l of the motor vehicle . the elastic connection points 9 , 9 ′, 9 ″, 9 ′″, which serve as force transfer points , are formed integrally with the frame element 7 by textile folding . by virtue of the connection points 9 , 9 ′, 9 ″, 9 ′ so formed , there is elasticity or flexibility in the direction of the longitudinal axis l and at the same time rigidity in the direction transverse to the longitudinal axis l . to further reduce the bumpiness of the chassis as already described earlier , in the area of connection to the body , i . e . at the elastic connection points 9 , 9 ′, 9 ″, 9 ′″ the support structure 1 is formed with a taper , i . e . the hollow space 6 between the upper shell 2 and the lower shell 3 becomes narrower . the distance between the upper and lower shells 2 , 3 is at most 5 mm at the tapered elastic connection points 9 , 9 ′, 9 ″, 9 ′″. along the respective elastic connection points 9 , 9 ′, 9 ″, 9 ′″ in the direction toward the four - cornered frame element 7 , the upper shell 2 and the lower shell 3 are v - shaped over a length of 10 to 20 cm in an aperture distance of 10 cm . in an alternative embodiment not shown in detail here , if the support structure 1 has only two elastic connections 9 , 9 ′″, then the frame component 7 would end approximately at the broken line indexed 10 in fig1 b , so that the elastic connection points 9 , 9 ′″ are only connected by a bracket - like element , in this case indexed 11 . in contrast , in the variant with four elastic connection points 9 , 9 ′, 9 ″, 9 ′″ there are also four bracket - like elements 11 , 11 ′, 11 ″, 11 ′″, which then form the frame element 7 . by providing the elastic connection points 9 , 9 ′, 9 ″, 9 ′″ made integrally with the frame element 7 as described above , the provision of additional rubber mountings is superfluous . the folds 12 , 12 ′ ( see fig2 ) formed by textile folding along the edges of the support structure 1 and the likewise formed elastic connection points 9 , 9 ′, 9 ″, 9 ′″ serve as force transfer points by virtue of the through - going fiber structure of long or continuous fibers in the plastic of the support structure 1 . fig2 shows a perspective view of a front portion of a support structure 1 according to an embodiment , in which the support structure 1 is additionally provided with reinforcing elements 13 , here in the form of reinforcing ribs . the collars 14 also formed by textile folding on the underside 15 of the support structure 1 can additionally be provided with reinforcing elements . the reinforcing elements 13 can be made as plastic moldings , in particular of fiber - reinforced thermoplasts or duroplasts .
