Problems solved by technology

However, depending on the positioning of the wheelhouse cross member arranged on the upper side, this tool access of the spot welding tongs to the engagement point of the rear cross member can be obstructed or completely covered.
In this case form constraints when assembling the underbody structure

Embodiment Construction

[0026] exist figure 1 Figure 2 shows an underbody structure for the rear side of a vehicle, wherein the storage space 1 on the rear side is delimited by a rear floor part 13 and outwards in the vehicle transverse direction y by a rear wheel housing 7 in each case, wherein, exist figure 1 Only the wheel house panel 5 is shown. exist figure 2 Here, the wheel house panel 5 has a peripheral wall 9 extending at intervals around the rear wheel 7 and transitioning inwards in the vehicle transverse direction y to a vertical side wall 11 of the vehicle interior. The side wall 11 is connected on the bottom side to the rear floor part 13 , for example by solder joints. like figure 2 It is further shown that the inner corner region between the side walls 11 of the wheel house panel 5 and the rear floor part 13 is reinforced with wheel house cross member reinforcements 15 .

[0027] exist figure 2 The wheel house cross member reinforcement 15 has, on the wheel house side, a shell-...

Abstract

The invention relates to a body floor structure for a two-lane vehicle having a cross member arrangement (36) in the rear vehicle body; the rear vehicle body consists of heel cover beam (19) extendingabove on the bottom plate and the rear wheel housing (5) and one rear cross member (37) which is adjacent to the rear wheel housing (5) along an axial direction (x) of the vehicle, the rear cross member (37) is made of a beam plate member (39) having an open hollow section, and the beam plate member (39) is connected to a bottom side of a bottom plate at a joint positions (F1, F2) of the front and rear portions in the longitudinal direction (x) of the vehicle in the case where a closed hollow section (47) is formed.

Description

technical field [0001] The invention relates to an underbody structure for a dual track vehicle according to the preamble of claim 1 . Background technique [0002] During driving operation, in particular in the case of cornering, the rear side of the vehicle body is loaded with torque directed about the vehicle longitudinal center axis, the rear side of the vehicle body being twisted relative to the front side of the vehicle body. In order to increase the torsional rigidity, it is known to reinforce the inner corner region between the rear wheel housing and the floor panel on the luggage compartment side with corner reinforcements. To further increase the torsional rigidity, two opposite corner stiffeners can be connected to the wheel arch cross member. [0003] This underbody structure has a cross member arrangement in the rear of the vehicle, which is formed by a wheel house cross member and a rear cross member. The wheel house cross member is arranged above the floor, ...
