GEARLESS WORKING AND TRANSPORTATION TRICYCLE WITHOUT MECHANISM FOR SYNCHRONIZED MOTION OF PEDALS

摘要

Gearless working and transportation tricycle comprises a frame (11) whereon are inbuilt a steer vheel (2) with front wheel (3), a seat (5), a double pedals (l) of extended length of arm lever, rotary by an angle (α); a device (U2) for stabilization of the levers of pedals; a device (P3) for conversion of an alternating rotary motion into one-way rotary motion without gears in the power transmission; assembly (Z’) of a back driving axle; and a connecting shaft (B), a draw-bar hook V and a front shelf (1111) and a rear shelt (1112). This concept enables the use of tricycle as: working and transportation vehicle, particularly in hot houses and greenhouses, means for internal transportation, unpolluting for environment, and vehicles for transportation of people and bulk material.
