Abstract
Distributed hub drives electric vehicles highly integrate the drive motor, deceleration mechanism, etc. in the wheel. As a key component of the hub drive system, the structure and performance of the reduction mechanism will directly affect the driving and safety of the vehicle. How to realize the integrated design of the reduction mechanism and other parts of the hub drive system in limited wheel space is one of the basic problems to be solved in hub drive system design. In this paper, the NGW-type planetary mechanism is used as the hub reduction mechanism, combined with other parts of the hub drive system to design the specific structure of the planetary reduction mechanism, establish the kinematic model of the reduction mechanism, and carry out the kinematic simulation analysis.
