Direct current linear actuator using in the active suspension system of automobile

The active suspension system passes the action power produced by the actuator to improve performance and safety of vehicle. For the current prevalence of actuator in the active suspension there are many shortcomings, such as slow response, more energy consumption, low efficiency of storage energy, bad reliability, making the suspension frame more complex. A novel active suspension with energy by DC linear actuator is presented, and the structure principle of this active suspension and design scheme of this DC linear actuator are stated, and proposed DC linear actuator in the active suspension of automobile control system.
