TRANSMISSION FOR SMALL VEHICLE

摘要

PROBLEM TO BE SOLVED: To ensure an effective engine brake function while simplifying the structure of a transmission mechanism by appropriately selecting the transmission mechanism for leading in engine brake force in a fluid transmission provided with a torque converter. SOLUTION: The fluid transmission is provided with a centrifugal clutch 14 and the torque converter 15 arranged on a crankshaft 11, and the driving force of the crankshaft 11 is inputted to the torque converter 15 from the centrifugal clutch 14 and transmitted to a reduction gear G1 through a turbine shaft 17a of the torque converter 15 and further transmitted to driving wheels. Engine brake force is transmitted from the reduction gear G1 to a turbine hub 17b which is a clutch outer 19a of a one-way clutch 19 via the turbine shaft 17a and further to the crankshaft 11 from a clutch inner 19b of the clutch 19.
