Filed: 1978-09-02
Abstract: PURPOSE: To obtain stable and big braking force in such a way that an elastic material to be resistive to the movement of this movable material at the time of braking is provided in the space between it and a fixing material to the movable material to connect between a pair of shoe ends.  
     CONSTITUTION: When a pairs of shoes 4, 5 are expanded by a drive device between ends unshown in the figure, rotation of a drum counterclockwise draws a shoe 4 and presses a cylindrical material 12 to thrust a shoe 5 on the other side. Since a coil spring 15 is inserted in the space between it and a solid box material 11 on both sides of a collar part 12a at the middle of the cylindrical material 12, part of output from the shoe 4 is absorbed by this spring 15. In consequence, even though self servo action is smaller in comparison with D.S type drum brake, braking force can be stabilized, in addition, it is obtainable of a larger braking force than L.T type drum brake.
