摘要： 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.

摘要： A rotary feed-through, designed to transfer a fluid between two entities in rotary motion with respect to one another, is described. The rotary feed-through comprises an inner cylindrical ring and an outer cylindrical ring, which are free to turn with respect to one another and are provided with channels for passage of the fluid. The channels are connected via at least one annular space axially delimited by seal rings housed in a cylindrical seat. The cylindrical seat faces radially outwards or inwards and is axially delimited, on one side, by an axial abutment of the inner and outer cylindrical rings and, on the other side, by an axial abutment of a lid, or of a closing ring, or of an intermediate ring. The seal rings are interference fitted to the inner cylindrical ring or outer cylindrical ring and are provided with an elastic portion for contact with the surface of the inner cylindrical ring or outer cylindrical ring. The rotary feed-through comprises means that prevent the axial movement of the inner cylindrical ring with respect to the outer cylindrical ring. At least one bearing is arranged between the inner and outer cylindrical rings and is configured for supporting both the radial load and the axial load between the inner and outer cylindrical rings. The inner cylindrical ring is provided with at least one first shoulder and the outer cylindrical ring is provided with at least one second shoulder, which is set in front of the first shoulder. Each bearing is arranged between a first shoulder and a second shoulder, so that the bearing constitutes an axial constraint in regard to the possibility of mutual axial sliding between the inner and outer cylindrical rings, the axial constraint maintaining the mutual position between the inner and outer cylindrical rings during mutual rotation.

摘要： A solid tyre (4; 8) is described comprising two or more circular layers overlapped in a radial direction. At least the outermost layer is made of elastic material and consists of an external portion or tread (16). The solid tyre (4; 8) furthermore comprises at least one layer for indicating excessive wear (10), arranged in a predefined position inside the outermost portion or tread (16). The layer for indicating excessive wear (10) is made in a colour different from the one of the external portion or tread (16). The layer for indicating excessive wear (10) is made with a specific compound of materials. This specific compound of materials makes the layer for indicating excessive wear (10) easy to see. This specific compound of materials also makes the solid tyre (4; 8) less hysteretic, and therefore less subject to the development of heat, when compared to similar solid tyres according to the prior art.
