An embodiment running bare chassis assembly includes a front frame on which a front suspension is mounted, a rear frame assembly on which a battery carrier is mounted, wherein the rear frame assembly comprises, a first rear frame on which a rear suspension is mounted, a second rear frame coupled to the first rear frame and on which a radiator is mounted, and a battery carrier frame on which the battery carrier is mounted and which is coupled to the first rear frame through a second engagement, and a center frame coupled to the front frame and the rear frame assembly through a first engagement, wherein a stress distribution due to the first engagement is greater than a stress distribution due to the second engagement.

A device for reinforcing, sealing, or damping a structural element in a motor vehicle including a support which has multiple cells, wherein each cell surrounds a cavity. Each cavity is at least partially delimited by walls in each direction, wherein each cell has an extension in length, height, and width between 5 mm and 100 mm. An outer surface of the support can be connected to the structural element by an adhesive.

A vehicle front portion structure includes: a battery case that is installed beneath a floor of a vehicle; front side members that extend in a vehicle longitudinal direction further toward a vehicle front side than the battery case; side rails that structure portions of a suspension member that is disposed further toward the vehicle front side, and that extend in the vehicle longitudinal direction; first connecting members that connect the battery case and the front side members; and second connecting members that connect a vehicle longitudinal direction front end portion of the battery case and vehicle longitudinal direction rear ends of the side rails, that face the battery case in the vehicle longitudinal direction as seen in a plan view and in a side view, and that face the side rails in the vehicle longitudinal direction as seen in a plan view and in a side view.

A plurality of structural fibers are laid onto a substrate. The plurality of structural fibers are stitched together with a thread in a specified stitching pattern to form a composite preform. The thread in the specified stitching pattern secures the structural fibers to each other such that the structural fibers provide a tailored load path within the composite preform and presents a visible image on an outer surface of the composite preform.

A body front-end structure for a two-track vehicle, having an A-pillar from which an upper wheel well longitudinal member projects toward the front of the vehicle in the longitudinal direction of the vehicle, and from which a lower body longitudinal member that is offset toward the inside of the vehicle with respect to the upper wheel well longitudinal member projects toward the front of the vehicle in the longitudinal direction of the vehicle. In a head-on crash with small lateral overlap, a suspension strut dome is loaded with a crash force in the longitudinal direction of the vehicle. The body front-end structure has a sheet-metal tension strip that connects the suspension strut dome to the lower body longitudinal member in a force-transmitting manner. In the event of a head-on crash, the sheet-metal tension strip provides a load path through which a tensile force opposing the crash force acts on the suspension strut dome.

Disclosed is a device for attaching, to a motor vehicle chassis, the rear end of the side rails of an engine cradle receiving an electric drive propulsion system for the vehicle. According to the device of the invention and for each of the side rails (3a, 3b), the attachment device comprises a junction interface (5a, 5b) that includes at least a first junction member (7a, 7b). The first junction member (7a, 7b) is, on one hand, attached longitudinally (L1) to the rear end (4) of the side rail (3a, 3b) via a front end (8a) of the first junction member (7a, 7b) and, on the other hand, attached transversely (T1) to a lateral side member (1a, 1b) constituting the chassis (1) via a rear end (8b) of the first junction member (7a).
