| In this paper some dynamic performance of metal pushing V-beltcontinuously variable transmission (CVT) used in a car is discussed indetail. Force situations are found out at all operating modes by means ofmodeling dynamic mechanics and also provide Principles to determine itsoperating ways. Furthermore, many sliP reasons are analyzed to find outmain one and point out how to reduce slip between pulleys and belt.Courses of efficiency loss are discussed in addition. CVT's detailedoperating modes are analyzed when a car is driven. Sbolation on CVT'sauto-speed-change function is made. Therfore, its controlling Program isworked out in Matlab language also.The study results show tha cars with metal pushing V-belt type CVTwill own better performance than those with traditional step transmission orauto-speed-change transmission provided design it reasonably useexperiments results and theories we got. The main virtue of CVT isconvenient operation and can realize the best matching with the engine.After simulation calculation, the virtue is certified. Moreover, based onexperiments, the dynamic model mentioned in this paper could perfectfurther and become the important pall of CVT's theory. |
