Abstract: A method for automatic adjustment of the performance of a vehicle including the steps of detecting at least one significant physical quantity for checking the performance of the vehicle; defining at least one pair of reference indicators correlated with that physical quantity; saving at least one value of a said reference indicator in a predetermined nominal reference condition; detecting at least one value of a said reference indicator in a real operating condition of the vehicle; comparing said nominal reference indicator and real reference indicator and, if their values are different from each other, and implementing a correction of the driving power of the vehicle to compensate for the difference ascertained.

Abstract: Mechanical coupling for elastic axial and radial constraint with torsional freedom, especially for elastic pivots and suspensions and the like, comprising, according to the invention, a composite tubular member made of metal and elastomer (11) that exhibits high axial and radial rigidity and the ability to absorb vibrations induced by the mechanical system in which it is fitted and to compensate for manufacturing tolerances in that system, and a tubular insert (15), made of nonwear plastic material with a low coefficient of friction which is coaxial and integral, in the form of a fixed inner sleeve, with said composite tubular member (11) and engages with a rotating metallic component (16) fitted coaxially with respect to said tubular insert to provide the torsional freedom.

Abstract: A bearing structure for cabinets preferably containing electric and/or electronic apparatuses is provided, which comprises a predetermined number of metal section members, defining upright elements (2) and crosspiece elements (3), and connectors (4) between the section members which is adapted to be disposed in an operatively functional position to join the upright elements (2) to the crosspiece elements (3) independently of engagement of panels defining the cabinet top and base with the crosspiece elements.
