1. A motor vehicle rear structure, comprising:
an underframe component to support a motor vehicle floor and in which a tunnel is formed;
an axle component comprising a central part and, on each side of the central part, two lateral parts defining, with the central part, a space to accommodate a component of the vehicle;
an articulation device comprising a first articulation element and a second articulation element which are able to pivot relative to one another, the first articulation element being fixed to or integrated into the central part of the axle component and the second articulation element being fixed to or integrated into the underframe component, the rear structure being arranged in such a way that the first and second articulation elements are able to pivot relative to one another about an axis that is substantially horizontal and substantially perpendicular to a direction of travel of the vehicle in a frame of reference of the motor vehicle, when the first and second articulation elements are thus fixed to or integrated into the central part of the axle component and to the underframe component of the motor vehicle, respectively; and
at least one front reinforcing element fixed to the second articulation element and to the tunnel, the rear structure being arranged in such a way that said at least one front reinforcing element allows at least some of a load in the direction of travel of the motor vehicle derived from the axle component to be transmitted to the tunnel.
