- vehicles in the extended vehicle variant, larger
- Vehicle wheels installed to maintain greater ground clearance.
- smaller-diameter vehicle wheels are installed in the basic vehicle variant, which results in reduced ground clearance between the traction battery and the roadway.
- both in the basic vehicle variant and in the extended vehicle variant the bumper is positioned at the same height as required by law.
- both the basic vehicle variant and the extended variant are in the state of the art
- Vehicle variant the bumper positioned in the middle of the body side members. in the
- Vehicle variants is associated with high manufacturing and component costs: In terms of production technology, geometrically adapted rear floor assemblies must be kept available for both vehicle variants.
- the component geometry of the two rear floor groups is based on the different wheel diameters of the two
- Vehicle variants as well as adapted to the legally prescribed ground clearance of the bumper from the road.
- a rear bumper arrangement is known from US 2008/0315597 A1.
- a rear bumper arrangement for a motor vehicle is also known from US 2011/0175380 A1.
- the object of the invention is to provide a body structure for a two-lane vehicle in which vehicle variants with different sizes of ground clearance can be produced in a simple manner in terms of production technology.
- a central arrangement of the bumper on the body side members is dispensed with.
- the bumper in the extended vehicle variant
- the bumper is arranged off-center on the side members of the body.
- an adapter is provided according to the invention in the extended vehicle variant, which is supported in a force-transmitting manner between the bumper and the respective body side member in order to compensate for such an eccentric introduction of force.
- the distance between the bumper and the road surface remains constant across all vehicle variants.
- the rear bumper is arranged in the center of the body side members.
- the larger-diameter ones are in the extended vehicle variant Vehicle wheels are installed and the rear bumper is off-center on the
- Body side members positioned, i.e. by a vertical dimension compared to the
- Body side member moved to the bottom of the vehicle.
- larger-diameter vehicle wheels can also be installed in the basic vehicle variant and the rear bumper can be arranged in the middle of the body side members.
- the smaller-diameter vehicle wheels would be installed in the extended vehicle variant and the rear bumper would be positioned off-center on the body longitudinal member, i.e. offset by a vertical dimension compared to the body side member to the top of the vehicle.
- the bumper in the extended vehicle variant can be positioned eccentrically to the longitudinal body members.
- the bumper can exemplarily follow the respective longitudinal body member in the vertical direction of the vehicle
- the adapter Project beyond the bottom of the vehicle, to be precise with the formation of an inside corner area which is spanned between an underside of the body side member and the bumper.
- the adapter is a corner reinforcement part.
- the corner reinforcement part can be supported directly or indirectly in the inner corner area on the underside of the body side member and on the bumper.
- the two body side members each end with a bulkhead on the rear, to which the bumper is mounted.
- the adapter cannot be connected directly to the bumper, but rather to a bulkhead overhang that protrudes beyond the body side member towards the bottom of the vehicle.
- a bulkhead plate can be installed in the extended vehicle variant, which provides an enlarged bulkhead plate overhang compared to the basic vehicle variant, which forms a sufficiently large support base for the adapter.
- the adapter is preferably designed to be sufficiently rigid and has a component weight that is as reduced as possible.
- the adapter can be a wedge-shaped sheet metal part.
- the sheet metal part can have a profile base facing the roadway, from which side walls are raised.
- the profile bottom of the sheet metal part can be ramped with a decreasing component height towards the front of the vehicle on the underside of the Body side member.
- the shaped sheet metal part can preferably be in a spot-welded connection with the body side member and with the bulkhead plate.
- Figure 1 in a side view of a vehicle in the basic vehicle variant with partial
- FIG. 2 shows a side view of the rear floor assembly in the basic vehicle variant with little floor clearance
- FIG. 3 shows, in a view corresponding to FIG. 2, an expanded vehicle variant with a large floor clearance
- FIG. 4 shows a perspective partial view from below of the vehicle onto the rear floor assembly of the extended vehicle variant.
- FIG. 1 an electrically operated, two-lane vehicle is shown with a partial elevation in the rear part of the vehicle.
- the vehicle has a traction battery 1 (Figure 2 or 3). This is arranged in an assembly space provided on the underside of a vehicle floor 3 (FIG. 2 or 3).
- the assembly space extends in the vehicle longitudinal direction x between a front cross member, not shown, and a rear cross member 5 (FIGS. 2 to 4).
- a rear floor assembly connects to the rear cross member 5.
- the rear floor assembly has side body side members 7 which each end with a bulkhead plate 9 at the rear.
- a bumper 11 is positioned on the bulkhead plate 9.
- the ground clearance a of the bumper 11 to the roadway 21 is stipulated by law, i.e.
- the traction battery 1 has a rotating
- Housing flange 13 which, among other things, engages under the rear cross member 5 and is screwed to this.
- An auxiliary frame 15, which carries a drive unit with an electric machine 17, is connected to the two body side members 7 via connection points A1 and A2.
- Electric machine 17 is drivingly connected to rear vehicle wheels 19.
- FIGS. 1 and 2 the vehicle is shown in a basic vehicle variant B in which the bumper 11 is arranged centrally, that is to say in longitudinal alignment with the two body side members 7. In this way, in the event of a rear-end collision, a central force is introduced
- Rear crash force F (Figure 2) in the body side member 7 guaranteed.
- the vehicle wheels 19 have a wheel diameter d B which is smaller than the wheel diameter d E in the expanded version described later
- Vehicle variant E ( Figure 3 or 4).
- the small wheel diameter d B results in a low ground clearance f B between the traction battery 1 and the roadway 21 in the basic vehicle variant B
- the rear floor assembly with its body side members 7 is raised by a vertical dimension Dz, while the bumper floor distance a of the bumper 11 remains unchanged in order to meet the legal requirements.
- the bumper 11 is therefore no longer central, but rather eccentric, i.e. offset by the vertical dimension Dz to the bottom of the vehicle
- Underside 25 of the body side member 7 and the bumper 11 is spanned.
- FIG. 3 shows an eccentric force introduction of the rear crash force F into the body side member 7.
- a corner reinforcement part is provided as an adapter 23 in FIGS. This is in that
- the corner reinforcement part or the adapter is implemented in FIG. 4 as a wedge-shaped sheet metal part which has a profile base 31 facing the roadway 21, from which side walls 33 are raised.
- the profile bottom 31 of the shaped sheet metal part runs in the form of a ramp with a decreasing adapter component height towards the front of the vehicle towards the underside 25 of the body side member 7.

Abstract
L'invention concerne une structure de carrosserie, en particulier selon l'une quelconque des revendications précédentes, pour un véhicule à deux voies, présentant un module inférieur arrière, constitué par des longerons latéraux (7) de carrosserie qui sont reliés à l'arrière à un pare-chocs transversal (11) et auxquels est relié un cadre auxiliaire (15), qui porte un groupe moteur (17) qui est relié de manière cinématique aux roues arrière (19) du véhicule. Selon l'invention, le pare-chocs (11) est positionné de manière excentrique, c'est-à-dire décalé de la dimension verticale (Δz), par rapport aux longerons (7) de carrosserie, suite à quoi, dans le cas de collision par l'arrière, les forces (F) de collision par l'arrière sont introduites de manière excentrique dans les longerons (7). Un adaptateur (23) s'appuie avec transmission de force, directement ou indirectement, entre le pare-chocs (11) et le longeron (7) de carrosserie respectif pour la compensation de l'introduction excentrique des forces.
