The dynamic wedging and friction characteristics of one-way clutch under transient loads from stator

The frictional characteristics, as well as its self-lock mechanism of the one-way clutch under working conditions were further explored. First of all, the wedge and friction characteristics of the one-way clutch under the corresponding working conditions were explored and analyzed by combining the transient-flow simulation and explicit dynamics. The results show that the loads transmitted by the stator and the one-way clutch are typical transient unsteady loads; during wedge process, both the transmission force and the contact stress of the one-way clutch are transient with an overshoot and finally converge. As for the wedging process, the self-lock characteristics turn out to be determined by the wedge angle and frictional coefficient, and influenced by the spring force.
