Abstract：The case design is a very important part of the design of full automatic continuously variable transmission. Based on the overall transmission scheme, this paper made a physical design of the case, and established the 3D modeling of the case on Pro/E. The case was made a strength analysis by using finite element analysis software. The assembly of main components was finished and the two-dimensional drawings were exported.
