Electromagnetic Linear Actuators in Suspension Systems
- The use of electromagnetic linear actuators in automobile suspensions is under development.
- The reliability of electrical drives and the unconstrained integration with electronic control systems are factors that justify their use.
- Rotational electromagnetic actuators have been proposed, however, their use requires a gearbox to convert the rotational movement into linear movement and to increase the force value. Linear actuators do not require a gearbox.
- The main objective of ground vehicle suspension systems is to isolate the vehicle body from road irregularities in order to maximize passenger ride comfort and to produce continuous road-wheel contact, improving the vehicle handling quality.
- Today, three types of vehicle suspensions are used:
passive, semi-active, and active. All systems implemented in automobiles today are based on
hydraulic or pneumatic operation. However, these solutions do not satisfactorily solve the vehicle oscillation problem, or they are very expensive and increase the vehicle’s energy consumption.
- Significant improvement of suspension performance is achieved by active systems, however, they are expensive and complex.
