Abstract

The invention discloses a lever-type double-drive bicycle, which comprises a steering wheel at the front, a driving wheel at the rear and a power transmission mechanism for the driving wheel on the vehicle frame. The driving wheel includes a front driving wheel and a rear Flywheels are respectively installed on the axles of the front and rear drive wheels on both sides of the frame; The ring meshes with the flywheel on the same side of the rear drive wheel, the arc-shaped rack set on the rod body of the pedal meshes with the flywheel on the same side of the front drive wheel, and the front end of the pedal is equipped with a pedal; the left and right pedals are suspended through the frame. rope pull. The invention adopts a double-drive mechanism. When alternately stepping on the pedals, the rack and the ring gear on the pedal simultaneously drive the front drive wheel and the rear drive wheel to obtain double power and achieve the purpose of fast riding and energy saving.

Description

technical field [0001] The invention relates to a pedal bicycle, in particular to a lever type double-drive bicycle. Background technique [0002] Pedal bicycle is people's commonly used means of transportation, and its conventional form has two-wheeled bicycle, three-wheeled bicycle and multi-wheeled bicycle, and the front wheel of described three-wheeled bicycle is direction wheel, and two wheels side by side are trailing wheel, or rear wheel The wheels are two wheels arranged front and rear, the front wheels of the multi-wheeled bicycle are steering wheels, and the three or more wheels arranged front and rear are rear wheels. [0003] No matter what type of pedal bicycle, its transmission mechanism is that the pedal drives the center shaft to rotate through the pivoting arm, and drives the rear wheel through the sprocket transmission mechanism. Design restriction is the important reason that causes pedal bicycle to ride strenuously and speed can not be effectively improv...
