In front wheel drive cars, a fixed type CV-Joints is located at the wheel side, and a plunging type CV-Joints is located at the gearbox differential side ; both are connected by a interconnecting shaft. These are most popular applications of CV-joints. It is important for their design to analyze the internal forces of CV-Joints and the support bearing forces and moments. But in analysis of CV-Joint, only one CV-Joint is took up as the object up to now. For example, Kimata analyzes the CV-Joint internal forces considering all components' displacements and Hertzian deformations. But, it is inadequate in consideration of CV-Joints' mutual interactions on half-shafts application. In this paper, developping the Kimata's analysis, the system consisting of the interconnecting shaft, two CV-Joints with it's both end, and the support bearings is analyzed based on statics, then 3n^o+3n^i+32 (n^o: ball number of BJ, n^i: ball number of DOJ) simultaneous nonlinear equations are obtained. The equations can be solved numerically. From the solution, the contact forces acting between the joint's members, the induced forces and moments from CV-Joints, and the bearing forces and moments are obtained.
