Title:
MECHANICAL DISC BRAKE
Document Type and Number:
Japanese Patent JPS56116932
Kind Code:
A
Abstract:
PURPOSE:To prevent a spring from its turning movement caused by vibration and hold tension of the spring at constant in the spring for separating friction pads from a disc at release operation of a brake, by forming protrusions to a spring seat and adapting said protrusions to the spring. CONSTITUTION:If a lever 11 is turned, a nut 12 is rotated by the action of a ball 15 and grooves 13, 14 and displaced to the side of a friction pad 5 to press the friction pad 5 to a disc 2. If the lever 11 is released, tension of a spring 19 generates force to a direction for decreasing a distance between the nut 12 and ramp plate 10, then the nut 12 is reversely rotated to move a rod 16 backard and separate the friction pads 4, 5 from the disc 2. Both end faces 19a, 19b of the spring 19 are adapted to protursions 21, 22 respectively provided in a stopper 18 and spring seat 17 to control turning movement of the spring, thus the spring seat 17 is not rotated for the rod 16 by vibration. Accordingly, the spring 19, being changed in length between the stopper 18 and the spring seat 17, causes no change of the spring tension.
