Abstract :
The unsprung mass of direct wheel drive EV is increased significantly because of the in-wheel motor or motor with reducer. This brings the negative effects of the stability, safety and the ride comfort. In this paper, several schemes of direct wheel drive system for suppressing unsprung mass negative effects were proposed. A typical scheme was modeled and simulated to verify the suppression of unsprung mass negative effects. Then, a specific structural scheme for the single-link independent suspension direct wheel drive system with a dual-stage gearbox was proposed. And a prototype was made based on the research.
