A permanent magnet brake mechanism comprised of a permanent magnet, a guide ring, bearings inside a neck, a single-direction flywheel assembly of a rotatable outer hub disposed adjacent to the neck, a main shaft inserted through the bearings mounted in the rotatable outer hub, a sliding seat sleeved
A permanent magnet brake mechanism comprised of a permanent magnet, a guide ring, bearings inside a neck, a single-direction flywheel assembly of a rotatable outer hub disposed adjacent to the neck, a main shaft inserted through the bearings mounted in the rotatable outer hub, a sliding seat sleeved onto the main shaft and that is situated within the interior spatial confines at one side of the outer hub, a return spring installed at the exterior side of the sliding seat and on the main shaft that is also situated between the main shaft and the sliding seat, a brake line that is connected to the sliding seat and, furthermore, controls the movement of the sliding seat, and a guide key at interior side of the brake line that provides for the positioning of a mounting frame when the sliding seat slides along the main shaft. The innovative feature is that the permanent magnet is annularly disposed along the outer circumference of the sliding seat, with the outer lateral surface and the top surface of the permanent magnet coupled to the guide ring following the same outer circumference such that during the permanent magnet and guide ring coupling operation process, unitary construction heat dissipation elements capable of effective cooling are formed and, furthermore, situated between the interior side of the rotatable outer hub and the sliding seat.

[ What is claimed is:] [1.]1. A permanent magnet brake mechanism comprised of a permanent magnet, a guide ring, bearings inside a neck, a single-direction flywheel assembly of a rotatable outer hub disposed adjacent to the said neck, a main shaft inserted through the bearings mounted in the said rotatable outer hub, a sliding seat sleeved onto the said main shaft and that is situated within the interior spatial confines at one side of the said outer hub, a return spring installed at the exterior side of the said sliding seat and on the said main shaft that is also situated between the said main shaft and the said sliding seat, a brake line that is connected to the said sliding seat and, furthermore, controls the movement of the said sliding seat, and a guide key at interior side of the said brake line that provides for the positioning of a mounting frame when the said sliding seat slides along the said main shaft, the innovative feature of which is that the said permanent magnet is annularly disposed along the outer circumference of the said sliding seat, with the outer lateral surface and the top surface of the said permanent magnet coupled to the said guide ring following the said circumference such that during the said permanent magnet and said guide ring coupling operation process, unitary construction heat dissipation elements capable of effective cooling are formed and, furthermore, situtated between the interior side of the said rotatable outer hub and the said sliding seat such that the said structural assembly provides for simplified assembly and installation, stable performance and, furthermore, an entire structure in which brake torque can be continuously and steplessly adjusted.
