Clutch mechanism for motorized wheelbarrow or lawn mower has driving and driven parts coupled by clutch rollers in cooperation due to jamming effect

摘要

Clutch mechanism has driving (35) and driven (37) parts. The driving part has grooves (35c) receiving clutch rollers (73). The rollers are also fitting in grooves (71c) of the friction plate (71). When the driving part is in motion, the clutch rollers are in cooperation due to a jamming effect. The driving and driven parts are coupled so the energy can be transferred from one to the other.
