Abstract: In this paper, in order to explore the influence of multiple factors on the drag torque of the two-speed reducer, the influence of a two-speed reducer and oil product of an electric drive on the overall drag torque is explored by controlling the single factor one by one. Specifically, the oil quantity, oil temperature and structural resistance factors are analyzed and studied through experiments, and their influence on the drag moment is obtained. The test results show that the low speed is mainly the frictional resistance torque of the system structure parts. The high speed is mainly affected by the amount of oil, that is, the influence of the oil stirring resistance. And the temperature has a great influence on the oil stirring resistance, so as to ensure the appropriate oil temperature and greatly reduce the drag torque. This paper provides a direction for optimizing the resistance moment.
