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: The present invention relates to the system for measuring the slip of a tyre (10) with respect to a rim (20), on which said tyre (10) is mounted.
In particular, said system comprises a first electronic device (1) and a second electronic device (2), each of which is configured at least to acquire, filter, store and send data, and a processing unit (3), external to said electronic devices (1, 2), configured at least to receive and process the data sent by each electronic device (1, 2), in order to measure said slip by measuring an angle (α) and comparing the value of this angle with respect to at a reference angle αref.
The present invention also relates to method for measuring the slip of a tyre (10) with respect to a rim (20), on which said tyre (10) is mounted.
