RATCHET BICYCLE CLUTCH WITH SHOCK ABSORPTION OF TORQUE

摘要

FIELD: machine building. ^ SUBSTANCE: driven half-clutch (4) has cams (8) in form of cylinder sectors. Cams (8) have tangential blind orifices (10) wherein there are inserted cylinder springs (11) of compression. Also, driven half-clutch (4) functions as a sliding support for holder (9) of ratchets (12) which has internal slots corresponding to cams (8). Springs (11) rest against pushing surface of slots facilitating a gap between cams (8) and pushing surface of slots. ^ EFFECT: raised reliability due to reduced impact loads onto ratchets and ratchet teeth when cyclist begins to rotate pedals for acceleration. ^ 6 cl, 2 dwg
