<p>Disclosed is a magnetic fluid brake drum device, comprising a shell (1), a brake disc (2), a rotating shaft (3), a brake ratchet (4), a brake power cushion (5), a magnetic fluid (6), a brake fluid (7), an electromagnetic coil (8) and a controller (9). A magnetic field of the electromagnetic coil (8) is controlled by means of the controller (9), so as to change the specific gravity of the magnetic fluid in the brake power cushion (5), thereby changing the movement of the brake power cushion (5) by means of the change of specific gravity of the magnetic fluid (6), and driving the a brake block (11) and the brake disc (2) to conduct friction braking by means of the movement of the brake power cushion. The brake fluid can be used for reducing the temperatures of the brake block and the brake disc, so as to prolong the service life of the brake block and the brake disc.</p> |
