Abstract:
Rotatable discs are splined on a hub member and alternately arranged with stationary discs secured to the brake housing to form a brake disc assembly. The brake operator assembly is a combination electromagnet release, spring set assembly associated with a pressure plate and operative to selectively move the pressure plate into and out of engagement with the brake disc assembly for braking the assembly against and releasing the assembly for rotation. Primary torque springs are actuable, when the electromagnet is de-energized, for biasing the pressure plate into engagement with the brake disc assembly. Secondary torque springs are held against actuation to so bias the pressure plate by axially movable guide rods which include outer end portions engageable with outer fixed shoulders to hold the guide rods in a latched position. The secondary torque springs are actuated when the end portions of the guide rods are moved or cammed to an unlatched position, i. e. out of engagement with the shoulders.
