Problems solved by technology

[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. The limitation of the design is an important reason that causes the bicycle to ride hard and the speed cannot be effectively improved

Abstract

The invention discloses a lever-type double-drive bicycle which comprises a steering wheel arranged in the front of a frame, a drive wheel arranged on the rear portion of the frame and a power transmission mechanism for the drive wheel. The drive wheel comprises a front drive wheel body and a rear drive wheel body which are arranged in a front-rear mode. A wheel shaft of the front drive wheel body and a wheel shaft of the rear drive wheel body on the two sides of the frame are provided with flywheels respectively. The power transmission mechanism comprises foot bars arranged on the two sides of the frame respectively. The rear end of the foot bar on one side is meshed with the flywheel on the same side of the rear drive wheel body through a gear ring. Arc-shaped racks arranged on rod bodies of the foot bars are meshed with the flywheels on the same side of the front drive wheel body. The front ends of the foot bars are provided with pedals. The left foot bar and the right foot bar are pulled through a suspended rope on the frame. According to the lever-type double-drive bicycle, a double-drive mechanism is adopted, when the pedals are treaded with feet alternately, the racks and the gear rings on the foot bars drive the front drive wheel body and the rear drive wheel body at the same time, double parts of power are obtained, and the purposes of high riding speed and saving physical power are achieved.

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...
