Design of a Direct Wheel Drive System Utilizing Silent Chain Integrated with Semi-Trailing Suspension

The complicated structure and large unsprung mass of traditional distributed motor drive scheme have a negative effect on the ride comfort and ground adhesion. In order to solve this problem, a direct wheel drive system was proposed based on a silent chain integrated with semi-trailing suspension. The parameters of the drive motor and silent chain transmission device were collected from the requirements of the vehicle. The semi-trailing-arm wheel drive system was modeled and simulated with software ADAMS/Car, and the wheel alignment parameters were optimized with the help of software ADAMS/Insight.
