Abstract:
A tyre (3) for vehicles, which does not require pressurisation by means of a pressurised fluid, has a tread (16), two sidewalls (15), and two beads (8) attached to a wheel rim (2) and made of elastomer material; the tyre is provided with at least one tubular reinforcement body (18) which is associated with the tread; each of the sidewalls have a respective homogeneous resilient annular membrane (24).
Abstract:
A motor-vehicle wheel structure comprises a wheel rim and a wheel disk having a circumferential border bent and welded within the rim, and a central portion bearing a circumferential series of holes for engagement of bolts for fixing the wheel to the wheel support. The central portion is connected to the circumferential border of the disk by an intermediate annular portion having in cross section an arched configuration projecting outwards. Welded on the outer face of the wheel disk is an auxiliary disk having a substantially plane conformation, the outer border of which is welded to the main disk substantially in a position corresponding to the apex of the aforesaid projecting annular portion. The auxiliary disk integrates tubular columns that project from the inner face of the auxiliary disk and have their ends welded to the central portion of the main disk so that they are co-axial to the holes for the fixing bolts.

A tyre for vehicles which does not require pressurisation by means of a pressurised fluid has a tread, two sidewalls, and two beads which are attached to a wheel rim made of elastomer material, and is provided with at least one tubular reinforcement body which is associated with the tread; each of the sidewalls having a respective homogeneous resilient annular membrane, a straight generatrix of which forms an angle (A) other than 90° with the axis of the tyre; the membranes being stretched radially between the tread and the beads such as to be pre-tensioned in the absence of external loads acting on the tyre.
Abstract:
An airless vehicle tire, in particular for road vehicles, has a tread, which rolls on a road surface, and a reinforcing strip made of elastomeric material and for reinforcing the tread; the reinforcing strip being located inwards of the tread, being connected integrally to the tread, and having a number of adjacent blocks movable with respect to one another, and a circumferential forcing device for exerting force and a circumferential preload on the blocks.

The central portion is radiused to the circumferential border of the disk by means of an intermediate annular portion having in cross section an arched configuration projecting outwards. The intermediate annular portion has a plurality of embossed portions projecting outwards, configured in such a way as to define a plurality of spokes set at the same angular distance apart from one another.
