Abstract:

In connection with nearly 30 different international brands of hundred-ton series electric drive mining dump trucks,the structure of wheel reducers and the variation of the gear ratio's value were analyzed. According to the technical conditions of electric drive mining dump truck and the development situation of wheel motor, configuration and optimization of wheel drive system were described based on the calculation method of wheel motor's power and the gear ratio i of  wheel reducer.The results provide an important basis for the configuration and optimization of similar wheel drive system.

Key words: electric drive mining dump truck, wheel drive system, wheel reducer, gear ratio
