HIGH SPEED TRICYCLE OR QUADRICYCLE, CAPABLE OF EASILY DRIVING ON HILL SIDE ROADS EVEN IF HEAVY OBJECTS ARE LOADED

摘要

PURPOSE: A high speed tricycle or quadricycle is provided to prevent overturn accidents beforehand, and to selectively driving at a high speed or a low speed according to topography.;CONSTITUTION: A high speed tricycle or quadricycle comprises pedals(2), wheels(50), a freight compartment(60), and chains. The chains are connected to a low speed chain gear that is a smaller one among double gears(3,5-1) integrated to drive at a high speed and a low speed. When chain gears(12,14,16) integrated in a shaft rod(11) are simultaneously rotated while rotating the pedals, pulley chain gears(21,27) make a bicycle lighter. The double gears connected to the pulley chain gears control the speed by making the double chain gears be large or small according to topography. A free gear set(41) is respectively installed in rear wheels to prevent overturn accidents.;COPYRIGHT KIPO 2012
