【Abstract】 The structure and principle of electric driving mechanical transmission were introduced. The test bench of pure electric driving system for two gear EMT transmission was designed. On account of driving system transmission efficiency test,the construction and principle of test bench was emphasized. The whole experiment system uses CAN bus network and programmable logic controller( PLC) to achieve centralized acquisition for data and distributed control of equipment. The transmission efficiency test and analysis of power train system was realized. The results show that this test system entirely meets requirements,which provides data support and reference for parameter matching and optimization of pure electric driving system.更多还原
