Roller transmission is adopted, an acceleration roller is additionally arranged on a rear wheel, the speed ratio is 3: 1, two inertia stress application blocks are additionally arranged on the wheel, a tension spring is connected to the center of the wheel in order to save labor during starting, inertia stress application is generated under the action of centrifugal force during operation, friction force is reduced by 50%, efficiency is improved by 3 times, and four times of inertia stress application is achieved. And moreover, a speed changing function is achieved, a previous speed changer is improved, a chain is shortened, assembly is facilitated, and the problems of large friction force, low transmission efficiency and low speed are solved.
本发明是采用滚轮传动,在后轮加一个加速滚轮,速比按3∶1制作,再在车轮上加2个惯性加力块,为了启动省力用拉簧连接到轮中心部位,运转时在离心力作用下产生惯性加力,这样减少了摩擦力50%,提高了效率3倍,加上惯性加力有4倍,并且还有变速功能,将以前的变速器进行了改良链条也短了一些,方便了装配,解决了摩擦力大,传动效率低,速度慢的问题。
