Abstract:
A brake system for stopping rotation of a rotary element, wherein the rotary element has an outer surface, the brake system comprising:an outer element having an inner surface which encircles the outer surface of the rotary element, said inner surface of said outer element being spaced apart from the outer surface of the rotary element;a brake band positioned intermediate said inner surface of said outer element and the outer surface of the rotary element, said brake band having an inner surface facing the outer surface of the rotary element and an outer surface facing said inner surface of said outer element;actuating means for selectively frictionally engaging said brake band to the outer surface of the rotary element; andmeans for applying a force having a component normal to the outer surface of the rotary element to said outer surface of said brake band responsive to said brake band frictionally engaging the outer surface of the rotary element, whereby said means for applying a force causes additional braking force to be applied between said brake band and the rotary element in addition to a braking force exerted by said brake band on the rotary element due solely to said actuating means acting to frictionally engage said brake band to the outer surface of the rotary element.
