Structural improvement and shock absorbing performance analysis of in-wheel suspension integrated wheel

Because of its compact structure, it is difficult to design an effective shock absorption system in the traditional unicycle self-balancing car. To solve this problem, an integrated In-wheel suspension structure suitable for unicycle self-balancing car is proposed in this paper. By constructing the mathematical model of the damping system and using Simulink to construct the corresponding physical model, the amplitude-frequency characteristics of the suspension structure are evaluated. The results show that compared with the ordinary wheel with external suspension, the integrated In-wheel suspension structure not only achieves the equivalent shock absorption effect, but also shows better performance at the resonance frequency.
