ABSTRACT:
A vehicle braking system including a brake structure defining an annular surface; an annular magnet support disposed adjacent to the annular surface; a plurality of circumferentially spaced apart pairs of circumferentially spaced apart permanent magnets mounted on the magnet support and circumferentially spaced apart thereon, each pair arranged with like polarities facing the annular surface and the polarities of the pairs of permanent magnets facing the annular surface alternating circumferentially; an annular pole piece support assembly; and a plurality of ferromagnetic pole pieces mounted on the pole piece support assembly and circumferentially spaced apart in positions between the annular surface and the permanent magnets, each pole piece disposed adjacent to a pair of the permanent magnets and having a circumferential length substantially greater than the circumferential length of either of the adjacent pair of permanent magnets. Also included in the system is an adjustment mechanism for producing relative angular movement between the magnet support and the pole piece support assembly so as to change the circumferential alignment between each of the pole pieces and the pair of permanent magnets adjacent thereto.
