Abstract
In today's society, with the intensification of energy and environmental issues, purely electric vehicles as the only vehicle that can achieve zero emissions have achieved unprecedented rapid development. The electric wheel drive technology has become an important development direction in the field of electric vehicles with its unique advantages. The electric wheel is a driving wheel that integrates the motor and the wheel and can realize the independent driving of the wheel of the electric vehicle. Wheels generally have a wheel reducer.
This paper analyzes the research status and major problems of the electric wheel drive technology for cars at home and abroad. The design of the electric wheel is completed under the limitation of the reference vehicle's inner space and its dynamic performance requirements. A three-dimensional model was built using SolidWorks to verify the rationality of the structure.
The specific work of the dissertation is as follows: First, analyze the basic conditions of the front and rear wheels of the reference model, and complete the selection of the hub motor according to the dynamic performance of the vehicle. Then determine the main components in the wheel, complete the selection of the power transmission mode of the electric wheel, determine the connection mode of each component, and determine the overall layout of the electric wheel, providing a basis for structural modeling. Finally, the structural design of the electric wheel is completed according to the overall layout plan of the electric wheel. According to the design parameters of each part, through the SolidWorks technology, the rationality of the modeling and verification structure of the electric wheel is completed.
