Abstract: A joint between two bodies of limited relative mobility, such as the wheelbase and the chassis of a vehicle, comprises a male member or stem fastened to one body and a female member or socket fastened to the other body, the two members being interfitted with interposition of a resilient ring allowing universal elastic deformation. At least one member is secured to its body through a pivotal connection permitting a limited relative swing in a plane including the joint axis, the swing being resisted by a resilient cushion. This affords increased elastic deformability in a preferred direction, e.g. longitudinally of the vehicle.
