Abstract

The invention discloses a chainless type three-wheeled rowing bicycle which pulls a hand-pulling handlebar back and forth through rowing type action of arms so as to be driven to travel. The chainlesstype three-wheeled rowing bicycle effectively solves the problems such as chain dropping and chain separating of a conventional chained type bicycle. The chainless type three-wheeled rowing bicycle is characterized in that a hinged block is arranged on the bottom of one end of a bicycle body supporting frame, wherein a fixed lug is arranged on a bicycle head protective shell, and the bicycle headprotective shell is hinged with the hinged block through a supporting fixed pin; the bicycle head protective shell is of a hollow structure; a front wheel drive rotary shaft penetrates through the bicycle head protective shell; supporting bearings are arranged between the two ends of the bicycle head protective shell and a front wheel drive rotary shaft separately; two drive wheels are separatelyarranged at the two ends of the front wheel drive rotary shaft; the two ends of the drive rotary shaft are separately equipped with two groups of pawls; each groups of pawls consists of four pawls; pawls are separately arranged on the centre positions of the two drive wheels, and separately correspond to two groups of pawls on the drive rotary shaft; and one end of the hand-pulling handlebar is arranged on the bicycle head protective shell.

Description

technical field [0001] The invention relates to a chainless three-wheeled rowing bicycle, which relates to a chainless three-wheeled bicycle driven by rowing, and belongs to the field of vehicle equipment. In particular, it relates to a chainless three-wheeled bicycle which drives the bicycle by pulling the handlebar back and forth through the rowing action of the arm. Background technique [0002] The traditional chain bicycle drives the wheel disc installed on the central axis to rotate by stepping on the pedal, and drives the flywheel on the rear axle of the bicycle through the cooperation of the chain. Although the structure of the chain bicycle is simple, its transmission chain is often easy to fall off, resulting in the chain falling off. It is very inconvenient to reinstall the chain, and the oil that lubricates the chain will also stain the clothes. Now there are many chainless bicycles. , but its relative structure is also more complex, and maintenance is not easy....
