Band brake for a rotating member, and a clutch having such a brake
First Claim
1. A band brake for a rotatable member having a cylindrical bearing surface, said band brake comprising a brake band extending in a loop around a cylindrical bearing surface of said rotatable member, and a hydraulic operating member adapted to apply said brake band against part of said cylindrical bearing surface, said operating member comprising two elements independently movable in opposite directions and disposed between the brake band and the cylindrical bearing surface, said elements being disposed substantially radially in relation to said cylindrical bearing surface and in axial alignment with each other radially of said cylindrical bearing surface, one of said elements being cooperable with said brake band to apply said brake band against said part of said cylindrical bearing surface and the other of said elements being associated with a brake shoe to apply said brake shoe against another part of said cylindrical bearing surface diametrically opposite the first mentioned part thereof.

Abstract
A band brake for a clutch comprises a band, passed in a loop around a cylindrical bearing surface of a driven part of the clutch, and an operating member adapted to apply the brake band against part of the bearing surface, the operating member comprising two pistons hydraulically moveable in opposite directions in the same cylinder, one piston acting on the brake band and the other piston on the bearing surface, the pistons being actuated to brake the driven part of the clutch when the clutch is disengaged.
