Based on double trailing arm suspension, relating to two-wheel-drive structures with inhibition of vertical vibration: a motor-integrated electric wheel-drive system and an electric wheel-drive system of which the motor can swing up and down and act as a dynamic absorber. In the paper a unified differential equation of motion of the two electric wheel drive systems was deduced, and Matlab and Adams were applied to simulate and analyze the ride comfort of the two drive systems. The analysis results show that compared to the traditional In-Wheel Motor Driven EV, the vertical acceleration of the car body of either of the two drive systems is lower, which significantly increases the ride comfort of car. Between the two electric wheel-drive systems, the latter system with dynamic absorber motor is more efficient to inhibit vertical vibration.
