1. An energy storage floor assembly for a motor vehicle with an electric drive, comprising:
a storage housing in which an electrical energy storage device is accommodatable, the storage housing being arranged on an underside of a vehicle floor,
wherein the storage housing contains at least one longitudinal beam, a front end of which, viewed in a longitudinal direction of the vehicle, is at least indirectly connected to a crossbeam component, which is arranged in a region of a front-end structure and to which a front-axle support is attached; and
at least one load transmission element inserted between a rear region of the front-axle support and the front end of the at least one longitudinal beam, which the at least one load transmission element has at a front end a front supporting region and at a rear end a rear supporting region,
wherein, in an event of an accident-induced backward movement of the front-axle support as a result of a collision, the front-axle support is able to be supported on the front supporting region of the at least one load transmission element, and the rear supporting region of the at least one load transmission element is able to be at least indirectly supported on the at least one longitudinal beam,
wherein the front-axle support comprises two front-axle longitudinal beams, one of which in each case, respectively assigned to a side of the vehicle, is attached to the crossbeam component by way of two fastening points, one fastening point in each case lying opposite the front supporting region of a respective load transmission element in the longitudinal direction of the vehicle.
