Title: Automatic regulator of drum brakesigma brake gap
Inventor: TAGUCHI SUEMITSU
IPC: F16D65/56
Filed: 1978-06-28
Abstract: PURPOSE: To eliminate excess force at the interlocking of a control lever with a ratchet wheel even under excess braking force, by completing a brake gap regulating action while driving the control lever until a brake shoe comes in touch with a brake drum.  
     CONSTITUTION: When the brake is applied, pressure liquid is fed in a cylinder 32 to press a brake shoe 1 to the brake drum. The pressure liquid in the cylinder 32 then flows in a drum 21 during the time until the brake shoe 1 contacts with the brake drum, pushes a piston 9 leftward and turns a control lever 3 counterclockwise around a supporting shaft 27. Accordingly a nut 6 turns inside the piston 10 together with a ratchet wheel 4 interlocked to the lever 3, which screws in a regulating bolt 5 and reduces the brake gap between the brake shoe and drum. This means that there is no excess force at the contact of the lever with the ratchet wheel, even when an excess braking force is put on.
