Abstract:
A disc brake mechanism for small-wheeled vehicles comprising:a carriage that has an axle support structure with wheels mounted thereon that rotate freely and indent of one another so that said carriage can roll upon a surface; a heat-resistant, friction pad disc that is fixed to the central aperture of a wheel hub and which rotates with said wheels; a non-turning, heat-conductive rotor mounted to an axle support structure, wherein said non-turning rotor is controllably coupled with said friction pad disc to provide braking action; means for exerting a force upon said non-turning rotor to engage said friction pad disc; means for remotely act said disc brake mechanism; a spring for maintaining said brake mechanism in a non-activated configuration; wherein said non-turning rotor and said friction pad disc are not in engagement; wherein upon activation of said brake mechanism, frictional heat generated during braking operation is directed from said non-turning rotor into said axle support structure by conduction for dissipation, in of into the heat sensitive wheel components.
