Abstract

The utility model discloses a hand-driven tricycle, comprising a tricycle frame, a handle bar, a front wheel and a couple of rear wheels. The tricycle frame is arranged on a tricycle base, and the handle bar and the front wheel are mounted at the front end of the tricycle frame through a front fork. The rear wheels bilaterally and symmetrically assembled are positioned at the rear end of the tricycle frame. The rear wheels are respectively coaxial connected with a flywheel, and big gears meshed with the flywheels are respectively assembled. Each big gear is respectively coaxial connected with a pinion, and driving gear racks meshed with the pinions are respectively assembled. The controlling and driving modes of the existing bicycle and the hand-drive tricycle are thoroughly changed by the utility model. The handle bar is controlled by the feet, and the gear racks, the gearwheel and a flywheel driving device are driven by the hands. The driving of the tricycle is achieved. The control capability of the feet is effectively practiced, and the forces of the two arms are enhanced. The hand-driven can be used for the walking-substituting, and also can be used as the sporting apparatus of the leisure sport, the recreation and the sporting game.
