Structure of torsion shock absorber

摘要

An improved torsion shock absorber has a curved clevis rocker arm and a solid rocker arm. Mounting holes are formed through one rounded end each of the rocker arms and bush holes through opposite rounded ends, each having symmetrical notches respectively machined along the inner circumferences. A torsion shaft of a spring steel is inserted into the bush holes of the rocker arms, and into the holes of corresponding mounting rings and a torque seat, a faced washer and a bushing are placed in the bush hole opening of the solid rocker arm, and a C-shaped circlip is fitted into each of the two ends of the torsion shaft. The mounting holes of the clevis rocker arm and the solid rocker arm are then attached to different force receiving entities.
