Abstract
Continuously variable transmission contains the closed gear differential and the controlled device. The elementary toothed continuously variable transmission has form of the gear closed differential with two degrees of freedom. The gear differential with the closed contour of toothed wheels creates additional constraint and supports a transition regime of motion from a start-up to bi-mobile regime with independent stepless regulating. It is necessary to prove that closed gear differential in itself carry out a function of a controlling device. The equations of interconnection of power, kinematic and geometrical parameters of transmission in statics, kinematics and dynamics are searched out. The synthesis of transmission consists in determination of teeth wheels numbers on a condition of overcoming the given maximum moment of resistance.
