Abstract
Bearing structure (6) has identical bearing elements (61) in tension outside contact patch (A) with the ground and in compression in the contact patch (A). Bearing elements (61) are filamentary and are connected to radially inner face (23) of radially outer structure of revolution (2) by radially outer fabric (71) and to radially outer face (33) of radially inner structure of revolution (3) by radially inner fabric (72), respectively. Furthermore, mean surface density D of bearing elements (61) per unit area of radially outer structure of revolution (2), expressed in 1/m2, is at least equal to (S/SE)*Z/(A*Fr), where S is area, in m2, of radially inner face (23) of radially outer structure of revolution (2), SE is connecting area, in m2, of radially outer fabric (71) with radially inner face (23) of radially outer structure of revolution (2), Z is nominal radial load, in N, A is area of contact with the ground, in m2, and Fr is the force at break, in N, of bearing element (61).
