1. A motor vehicle rear suspension comprising: two longitudinal trailing arms, wherein each trailing arm has a stub-axle carrier at one, rear, end and, at an opposite, front, end, a substantially transverse axis of rotation defined by a first articulation and a second articulation which are configured to be connected to a body of the vehicle, the second articulations being situated transversely between the first articulations, and the axes of rotation of the trailing arms intersecting at a point of intersection belonging to a transverse mid-plane of the rear suspension, the transverse mid-plane extending in the longitudinal and vertical directions, wherein: one of the trailing arms is secured, at its second articulation, to a first support element extending toward the front of the rear suspension, the other trailing arm is secured, at its second articulation, to a second support element extending toward the rear of the rear suspension, and free ends of the first and second support elements are situated in the longitudinal and vertical midplane of the rear suspension and are connected to one another and held at a fixed distance apart in a substantially longitudinal direction by a connecting element that is pivotably mounted about at least one transverse axis at least at one of the free ends of the first and second support elements.
