EDDY-CURRENT TYPE SPEED REDUCER

摘要

PURPOSE:To prevent the braking of an eddy-current type speed reducer from being released even if the clutch is disengaged while a vehicle goes down a slope. CONSTITUTION:An eddy-current type speed reducer B takes braking by drawing a magnet supporting wheel 21 by an actuator A near to a braking drum 23 which is combined with an output rotary shaft 22 of a speed change gear of a vehicle. A clutch switch 5a which opens when clutching and a tile switch 12 which closes when the vehicle has a forward tilting are parallelly inserted and connected to a conduction circuit of an electromagnetic switch valve 16 which controls the actuator A.
