Abstract

The device (1) for the controlled wear of treads is adapted to wear at least one tread (2) of at least one tire (3) during the rotation of the latter around at least one axis of rotation (A), simulating wear on the road, and comprises: - at least one supporting body (4); - at least one movable body (5) coupled longitudinally in a movable manner along a rectilinear shock-absorbing direction (B), moving closer to and away from the tread (2), to the supporting body (4); - at least one wear tool (6), mounted on the movable body (5) and arranged, in use, to contact the tread (2) in order to wear it; - shock-absorbing means (7), positioned between the movable body (5) and the supporting body (4) and adapted to move the movable body (5) with respect to the supporting body (4) along the shock-absorbing direction (B) closer to and away from the tread (2) respectively, when the wear tool (6) encounters a depression (8) and a relief (9) of the tread (2), keeping the wear tool (6) in contact under pressure with the tread (2).

Abstract

The present invention relates to a machine (1) for the working of treads that comprises: • supporting means (2) of a tire (3) provided with a tread (4) to be worked by means of at least one working tool (5) mounted on the machine itself; • movement means (31) of the supporting means (2), operable in rotation around an axis of rotation (A) to rotate the tire (3) around the same axis of rotation; • adjustment means (6, 7, 23, 24) for adjusting the position of the tread (4) of the tire (3) with respect to the tool (5), provided with a first and a second adjustment body (6, 7) associated with the supporting means (2) and with the movement means (31) respectively, mechanically coupled to each other and mutually movable to adjust the mutual position of the supporting means (2) and of the movement means (31).

Abstract

Safety device (1) for wheels comprising at least a support body (6): - fitted in a wheel (2) having a tire (3) and a rim (4) associated with each other to define a first tube (5) containing at least a first pressurized fluid for the support of loads acting on the tire (3); and - having a support portion (7) adapted to come at least partially in contact with said tire (3) when said first fluid comes out of said first tube (5); with the support body (6) that defines a second tube (8) fitted in first tube (5) containing a second pressurized fluid and in that it comprises inflating means (12, 19) variable between: - a first configuration, wherein the inflating means (12, 19) are associated with the first tube (5) for the introduction/extraction of the first pressurized fluid; and - a second configuration, wherein they are associated with the second tube (8) for the introduction/extraction of the second pressurized fluid.

Abstract

A wind turbine device comprising a base frame (1) which supports a vertical axis wind operated rotor, the axis being associated to a user device and being contained in a matchingly-dimensioned cylindrical casing (15) exhibiting two openings (151, 151a, 152, 152a), respectively an inlet and an outlet, aligned perpendicular to the rotor axis, the casing being driven to rotate about the axis by means (27) sensitive to the direction of the wind, such that the inlet opening is always facing into the wind.
