Aimed at the design and selection of shift operating mechanism applied to AMT system of positive independent mechanical split path transmission. Verifies the rationality of the mechanism by test. Based on analysis of the positive independent mechanical split path transmission, shift force is calculated. According to the shift force and requirements in shift time, parameters of selection and shift operating mechanism are confirmed. The resulting time of selection and shift by calculation is consistent with the practical time from the test. It is found that the design of selection and shift operating mechanism is reasonable, and the feasibility of the application of AMT system for positive independent mechanical split path transmission proved.
