Speed increasing device of hybrid power bicycle

Abstract

The invention discloses a speed increasing device of a hybrid power bicycle, and relates to the technical field of manufacturing speed increasing devices on bicycles. The speed increasing device of the hybrid power bicycle comprises a speed increasing gearbox, the speed increasing gearbox comprises a box body, and a first big gear wheel, a second pinion, a third big gear wheel and a fourth pinion are arranged in the box body. The first big gear wheel and the fourth pinion are coaxially arranged, a bearing is arranged between the fourth pinion and a driving rotating shaft, and a wind wheel which is coaxially arranged with the bearing is fixedly connected to the outer circle of the bearing. A driven wind wheel is arranged on a support, and a chain wheel is compounded on one side of the driven wind wheel. One end of the driving rotating shaft is fixedly connected with a flywheel, and the chain wheel and the flywheel are in transmission connection through a chain. An air hose is arranged between the wind wheel and the driven wind wheel. The fourth pinion is a trapezoidal gear. A fifth gear which is perpendicular to the fourth pinion is meshed with the outside of the fourth pinion, and the axis of the fifth gear is connected with a drive rod. The free end of the drive rod is connected with an electric generator. By the adoption of the speed increasing device, the bicycle can be ridden easily and quickly, and energy consumption is of no need.

Description

Background technique [0001] The invention relates to the technical field of bicycle manufacturing, in particular to the technical field of manufacturing a speed increasing device used on a bicycle. Background technique [0002] Bicycles in the prior art mainly include a crankshaft, the crankshaft is fixed to the rotating shaft, the rotating shaft is fixed on the vehicle frame, crank arms are respectively fixed at both ends of the rotating shaft, pedals are installed on the crank arm, and the crankshaft is connected to a chain through a chain. The outer ring of the one-way flywheel is connected by transmission, and the inner ring of the one-way flywheel is fixed to the rear wheel of the bicycle through the rear wheel shaft, and the rear wheel shaft is supported on the frame; The disc drives the rear wheel to rotate and drives the bicycle forward. The one-way flywheel is composed of an outer ring, an inner ring and a one-way transmission mechanism arranged inside. The inner ri...

Problems solved by technology

Existing bicycles have the following shortcomings: the riding speed is slow, and the driving speed of both feet is limited, resulting in a lower riding speed, generally below 20 km / h. Therefore, people often change to ride electric bicycles or motorcycles in order to pursue speed. However, the batteries of electric bicycles will cause environmental pollution, and motorcycles need to consume fuel, a non-renewable resource.
