This article discusses the design of the reverse engineering of a number of techniques, including parts of the mapping, surveying and mapping components of the choice of the base, the installation of measures such as size, parts modeling process through the introduction of three-dimensional modeling can be seen that the parts of the general process and modeling software application skills. In this paper, the pulse of U34-type continuously variable transmission of the working principle, the working process, theoretical calculation is fully described in the pulse for the U34-type continuously variable transmission in different working conditions and working environments will provide a theoretical basis.
