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

[0027] exist figure 1 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 outwardly in the vehicle transverse direction y by a rear wheel housing 7, wherein exist figure 1 Only the wheel housing panel part 5 is shown in . exist figure 2 In this case, the wheel housing panel 5 has a circumferential wall 9 extending at intervals around the rear wheel 7 , which transitions inwardly in the vehicle transverse direction y into a vertical side wall 11 in the vehicle interior. The side walls 11 are connected on the underside to the rear floor part 13 , for example by welding spots. Such as figure 2 It is further shown that the inner corner region between the side walls 11 of the wheelhouse panel part 5 and the rear floor part 13 is reinforced with a wheelhouse cross member reinforcement 15 .

[0028] exist figure 2 Here, the wheelhouse cross member reinforcement 15 has a shell-shape...

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 two-track vehicle according to the preamble of claim 1 . Background technique [0002] During driving operation, in particular when cornering, the rear side of the vehicle body is acted upon by a torque directed about the longitudinal center axis of the vehicle, wherein the rear side of the body is twisted relative to the front side of the body. To increase the torsional rigidity, it is known to reinforce the inner corner region between the rear wheel housing and the floor on the luggage compartment side with corner reinforcements. To further increase the torsional rigidity, two opposite corner reinforcements can be connected to the wheelhouse cross member. [0003] Such an underbody structure has a cross member arrangement in the rear of the vehicle, which is formed from a wheelhouse cross member and a rear cross member. The wheelhouse cross member is arranged at the top on the floor, while the r...
