CPC H02K 49/04 (2013.01) [B61B 3/00 (2013.01); B61B 7/00 (2013.01)] | 13 Claims |
1. A carriage for moving in a cable and/or a rail comprising:
at least one wheel equipped with its own rotation shaft and configured to rotate on a cable and/or a rail;
braking masses positioned parallel to said wheel and made of non-magnetic material;
magnetic masses configured to generate a magnetic field; and
a self-adjusting device, connected to said braking masses and positioned inside said rotation shaft of the at least one wheel, configured for moving said braking masses close to said magnetic masses along a direction parallel to an axis of extension of the rotation shaft, as a function of an increase in a speed of rotation of said at least one wheel, in such a way that said magnetic masses generate eddy currents by electromagnetic induction defining a slowing force proportional to the feed speed of the carriage.
