Star wheel accelerating device and star wheel vehicle

Abstract

The invention provides a star wheel accelerating device and a star wheel vehicle. The star wheel accelerating device is composed of an inner gear ring wheel disc, a five-way star wheel frame and a coaxial driving wheel, the center of the five-way star wheel frame is a five-way part, three cantilevers forming 120-degree angles with one another are welded to the five-way part, the same star joint is welded to the top ends of the cantilevers, three same star wheels are installed on the star joint. A coaxial driving wheel is mounted on a star wheel shaft extending out of the other end of one star joint; the inner gear ring wheel disc is mounted on the middle shaft, so that the inner gear ring and the star wheel are aligned and meshed, and the star wheel acceleration device has an ultra-large speed-up ratio; the star wheel accelerating device is installed on a bicycle, a pedal generator car and various manpower machines, so that a star wheel car with an ultra-large speed-up ratio is formed, the riding speed of a miniature folding bicycle can be greatly increased, and the defect that the pedal riding function of an electric bicycle is lacked is overcome at one stroke; the invention has obvious technical progress and wide application value.

Description

[0001] Technical field [0002] The invention relates to a brand-new super-large acceleration ratio acceleration device, in particular to a star wheel acceleration device capable of overcoming the difficulty of pedaling an electric bicycle, and various bicycles with the star wheel acceleration device. Background technique [0003] The new national standard requires that electric bicycles must have the function of pedaling, but the commonly used 14″ electric bicycles are limited to technical conditions. The wheel has 22 teeth, the standard flywheel has 16 teeth, and the transmission ratio is only 1:1.375. Riding 7 or 8 kilometers is not as fast as walking. The lack of pedal riding function is a major technical defect of electric bicycles, which makes the pedal device a decoration. However, it is not easy to overcome this major technical defect. Press With a flywheel configuration of standard pitch 12.7, the wheel disc of a 14″ electric bicycle must have at least 80 teeth and a ...

Problems solved by technology

However, the obvious disadvantage of the acceleration shaft is that the structure is too complicated. In the small space of the hub, there are about twenty parts for the three sets of sun gears, planetary gears, and ring gears. The cost is high, the price is high, and maintenance is difficult. Now almost No one is using it anymore, and the key is that the acceleration shaft does not have a super-large acceleration ratio, which cannot solve the defect of the lack of pedal function of electric bicycles at all.
