Abstract
PURPOSE: To make a brake gap adjustable by a method wherein a strut is arranged and expanded between a pair of brake shoes for brake operation by fluid power and to reduce consumption of regulating material by a method wherein the said regulating operation is inhibited for manual operation or for parking brake operation.
CONSTITUTION: When pressure fluid is supplied to a cylinder unit 8 to apply the brakes, a pair of pistons protrude outside, a right and a left shoe 1 are expanded to generate a dampling force. Then, a regulating lever 3 is rotated by a spring 7 around a supporting axis 9 and a screw shaft makes one rotation with a ratchet wheel 5 and screwed out of a strut 4 to regulate a brake gap. On the other hand, when the lower end of a parking brake lever 2 is pulled to the left in a parking time, the intermediate part runs against the right end of the strut 4, pushes the left shoe 1 and damping force occurs by the synchronization with the right shoe 1. However, the regulating lever 3 is escaped from the ratchet wheel 5 by a projected piece 2a of the lever 2 through a lever 6 and the brake gap is not regulated.
