Abstract
Have no the class gearbox spread to mean under the function that is a certain to control, make the exportation stalk of machine turn soon can at two pole is worth the continuous variety in the scope of spread a way.But have no class gearbox is such a kind of device, it has active with from move two stalks, and can pass to deliver the middle of turning the Ju to lie quality(the solid, fluid and electromagnetism flows) to contact two stalks directly or indirectly to deliver power.When to lord, from move an axial contact relation to carry on a control, can immediately make spreading of 2 compare occurrence variety.(be worth to change in a row but at will inside the scope in two poles).Based on the analysis of various CVT and CVT bikes,in this dissertation ,we change some parts of the Kopp-B CVT forming a new kind of CVT used to the bicycle .They are used to input or output the power through the friction and a pair of helical gears is also used to adjust the speed, so the speed can change between 0.75 and 1.22.This research shows that when the CVT are used in the bicycle ,they can significant improve the performance of bike so that all customers can use it convenient.
