Problems solved by technology

This variable configuration across the stringers can easily be achieved by using deep-drawn upper and lower shell parts; however, since the wall thickness of the shell is limited to a narrow In the range of , a higher load capacity of the longitudinal beams in the transition area can basically only be achieved by means of an enlarged cross section, which results in a loss of space in the luggage compartment and passenger compartment

Embodiment Construction

[0026] figure 1 A side view of a motor vehicle is shown, in which the floor structure according to the invention is used. The floor structure in the interior of the vehicle comprises two longitudinal beams which run mirror images of each other on the right and left sides of the vehicle and which figure 1 The course of the side members is shown in the rear of the vehicle by dashed lines. The side members extend over the entire length of the vehicle, ie from the front bumper to the rear bumper, but their course in the front part of the vehicle is not shown because this is not important for the invention. exist figure 1 The part of the side member shown in is subdivided into a rear side member section 1 , a transition section 7 and a middle side member section 9 . The rear side member section 1 extends substantially horizontally forward from the rear bumper 2 . On each side of the rear axle 3 is connected a transition section 7 which extends below the rear seats 4 in the pass...

Abstract

A substructure for a motor vehicle has a first side member including an upper shell and a lower shell, which crosses a rear axle and extends at least as far as to under a passenger cell. In a transition region between the rear axle and the passenger cell, the side member includes at least one wall part which is fastened to the upper and the lower shell in a material-doubling manner.

Description

technical field [0001] The invention relates to a floor structure of a motor vehicle, which has a side member composed of an upper shell part and a lower shell part. Such a floor structure is described in the published German patent application DE 10 2012008 025.5. Background technique [0002] In a conventional manner, the longitudinal members of such a floor structure have a rear section which extends horizontally in the longitudinal direction of the vehicle along the luggage compartment of the vehicle and has a part which spans the passenger compartment of the vehicle essentially in a straight line. A section and a section connecting the two preceding sections to one another and for this purpose running obliquely in the longitudinal direction of the vehicle in the transition region between the rear axle of the vehicle and the passenger compartment. Such inclined transition regions are subjected to particularly high loads when the vehicle is involved in a collision and th...
