Abstract: This disclosure provides a vehicle suspension system. Actuating elements disposed on two sides of a vehicle body provide acting forces for the vehicle body, so that the vehicle body is in an equilibrium position. When the vehicle body deviates from the equilibrium position, a resultant force generated by the two actuating elements causes the vehicle body to return to the equilibrium position. The vehicle suspension system can overcome the problems that a vehicle body is easy to shake and difficult to balance due to a high degree of freedom of wheels in a suspension system connected by a linkage mechanism.
