MIT EINER FLUESSIGKEITSKUPPLUNG AUSGESTATTETER KRAFTUEBERTRAGUNGSMECHANISMUS

摘要

A power transmission mechanism equipped with a fluid coupling, an input shaft thereof interconnected to a power source being interconnected through the fluid coupling to an output shaft, and the output shaft being interconnected to a forward-rearward changeover mechanism including a speed changer; characterized by that forward-rearward changeover can be performed by providing a clutch mechanism in a housing of said fluid coupling, which automatically disengages a connection between the input shaft and the output shaft when the power source is in idling condition, and automatically engages it when the power source exceeds the idling condition.
