Abstract
As the energy crisis becomes more serious and people’s environmental awareness continues to increase, research and development of clean, energy-efficient, and safe automobiles have become the direction of the automotive industry. Among them, electric vehicles have the advantages of zero emissions during driving, diversification and high-efficiency of energy utilization, and easy realization of intelligence, making it one of the key areas for the development of new automobiles.
This design starts from the strengths of the electric vehicle of the wheel-side motor drive scheme and finds different kinds of reduction gears suitable for electric vehicles. From the different types of speed-reduction mechanisms, the planetary gear reduction mechanism most suitable for this design is selected. The design of the drive form of the planetary gear reduction mechanism and the parameters of the components have been designed. In order to reduce the mass and volume of the wheel reducer, the structure is relatively simple, and the transmission efficiency is higher and the work is more stable. Load design to improve the advantages of planetary gear transmission, and design of the wheel reducer axle housing, making the installation of reducer and other components easier and more uniform force, more reliable work, steering for front and rear suspension guide The mechanism provides a stable stress point, so that the designed wheel-side deceleration drive system can better realize the installation and connection with other parts to meet the different working conditions of the car during driving.
