  • Publication number: 20230406415
    Abstract: A combined floor assembly and energy storage device for an electrically driven passenger car includes a floor assembly on the lower face of which an energy storage device of an electric drive of the passenger car is arranged. A holding element, by which a rear end region of the energy storage device is held on the lower face of the floor assembly, and a rear cross-member, which is arranged on the lower face of the floor assembly and behind the energy storage device in the vehicle longitudinal direction are provided. In order to provide a combined floor assembly and energy storage device which offers especially rigid support for the rear cross-member even in a vehicle with a purely electric drive and in which, additionally, the energy storage device is fixed to the rear end on the lower face of the floor assembly in a particularly stable manner, the energy storage device is secured to the rear cross-member by way of the holding element.

  • Patent number: 11807305
    Abstract: A motor vehicle has a front-end vehicle structure which has a wheelhouse support structure on each side of the front-end vehicle structure, in each of which wheelhouse support structure a bearer extends from an A-column to an engine support via a suspension strut receptacle. An engine support is formed beneath each wheelhouse support structure. The front supporting bearer extends in a vertical plane in an arc from the suspension strut receptacle downwards to the engine support. The front supporting bearer extends in a horizontal plane in an arc from the suspension strut receptacle from the outside inwards in the direction of a longitudinal axis of symmetry through an angle to the engine support, and the front supporting bearer is fastened with the front end thereof to the engine support.

  • Patent number: 11702144
    Abstract: A motor vehicle has a body with a front section, a floor structure which adjoins the front section, and a floor panel, on the two longitudinal sides of which a sill is in each case arranged. The sills run from an A pillar, adjoining the front section, of the body as far as a C pillar of the body. An inner longitudinal member is on each longitudinal side of the floor panel. A bulkhead is arranged between the front section and the floor structure. Each sill is constructed from an inner C profile and an outer C profile. The first and second profile flanges of the C profiles, arranged in an overlapping manner, are connected, in particular welded, to the inner longitudinal member.
