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： The present invention relates to a system for measuring the length of a footprint of a tyre (10). 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 sent 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 the length of a footprint on the basis of an angle (β) arranged between a first axis (B1) passing through the center (O) of the tyre (10) and a first contact point (CP1) between a portion of said tyre (10) and the ground and a second axis (B2) passing through the center of the tyre (10) and a second contact point (CP2) between said portion of said tyre (10) and the ground. The present invention relates also to a method for measuring the length of a footprint of a tyre (10).

摘要： 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 (a) 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.
