Abstract: A rotary joint is configured to transfer a fluid between two entities, one of which is in rotary motion with respect to the other. The rotary joint comprises a cylindrical internal element, apt to be fixed to the entity in rotary motion, and a plurality of annular external elements. The external elements comprise at least two head elements, at least two housing elements of respective gaskets, two bearing elements, and at least one fluid inlet. The fluid inlet is placed between said two bearing elements. Housing elements of respective gaskets are arranged externally to the bearing elements, and head elements are arranged externally to the housing elements. The gaskets define an annular shaped sealed area. The sealed area is accessible on one side through said fluid inlet and on the other side through at least one fluid passage channel passing through the body of said internal element.

Abstract: A process and a device of control and regulation of the pressure of tyres apt to ensure the adaptation of the footprint of a tyre to changes in the load applied thereto. The process includes the following steps: measuring the pressure of the tyre, measuring the footprint or the deflection of the tyre, determining a calculated value of footprint or of deflection in function of said optimum value of pressure, said calculated value of footprint or of deflection being determined by means of a correlation, based on experimental data, of values of pressure, footprint or deflection and applied load, if said calculated value of footprint or of deflection is different from respectively said measured value of footprint or of deflection: modifying the pressure of the tyre to reduce the difference between said measured value of pressure and said optimum value of pressure.

Abstract: A wheel rim that includes a peripheral structure for receiving a tire, and a central structure for coupling with a hub of the vehicle. The peripheral structure includes, for each side of the wheel rim, a peripheral flange, a connecting wall on which the bead of the tire rests, and a connecting part. The peripheral structure includes a central well. The connecting part includes a first curved region which joins the central well, and a second curved region between the first curved region and the connecting wall. The second curved region has a convex profile from the side of the wheel rim with the tire, and includes a first curved surface joined to the connecting wall with a first radius of curvature, and a second curved surface between the first curved surface and the first curved region, with a second radius of curvature different from the first radius of curvature.

Abstract: FIG. 1 is a front right perspective view of a tire showing our new design, it being understood that the tread pattern of the tire repeats circumferentially about the outer circumference and shoulder of the tire;
FIG. 2 is a right side view thereof;
FIG. 3 is a left side view thereof;
FIG. 4 is a rear elevation view thereof; and,
FIG. 5 is a front elevation view thereof.
The broken lines shown in the drawings illustrate portions of the tire that form no part of the claimed design.
