MagneRide - An Electronically controlled Magnetic Suspension!

The suspension system in the vehicle comforts the body from the road shocks aid with a spring and damper. Springs absorb the shocks and tend to fluctuate while the wheels move on bumping roads, and dampers resist that fluctuation to a reasonable level. That's why it has the name "shock absorbers". It separates the body from the chassis, so decent stability with utmost tire-to-road contact can acquire and secures the occupants from the shocks.  

 

As per the vehicle's configuration (luxury, sportive, or medium), the suspension system with suitable damping effort and other adjustable parameters has combined to withstand the maximum shocks and achieves quality riding. In other words, it is classifying as an active and passive system. The active suspension works with onboard controls, which act as per the road conditions and have further classified based on working (real-active, adaptive, and semi-active). This system works based on the skyhook theory, which is a concept that maintains the object more stable even it strikes the bump-like conditions on straights. Passive suspension is the simple system that works after the wheels approach the bumps or potholes and react reasoningly.

The MagneRide suspension, technically is magnetorheological damper, comes under the category of an active but notably, it is a semi-active suspension (i.e.,) simply it varies the damping effect corresponding to the dynamic (real-time) conditions of the car via ECU commands. So compared to an active system, semi-active is maintenance-free and less expensive. 

Everything is fine! What makes MagneRide more Unique?

 

The technology inside the MagneRide seems more captivating because the fluid used in this damper makes it worthier than you think. Magnetorheological (MR) fluid is that one, which has fused with iron and oil (synthetic hydrocarbon base oil). Besides that, an electric coil has fitted inside the damper piston wired with ECU and control via sensor data. The unique thing is, no base valves and smaller parts are moving inside, and the damping piston has channels in it.

 

Then How MagneRide Works?

 

When the wheels approach bumps, the suspension tends to oscillate for a while. In dynamic conditions, continuous oscillations feel discomfort to occupants. As per that, an increase in damping effects in various conditions makes it more advantageous. Concerning that, ECU fetches data about the wheel speed, roll, and pitch movement of the vehicle from respected sensors and cross-check with the preset value. After that, it supplies an electric current to the coil inside the damping piston accordingly. Now, the coil gets energized and generates a magnetic field around accompanying by eddy current perpendicular to each other, as stated in Lenz's law. So the iron particles inside the fluid aligned about to generated magnetic field that tends the fluid denser (semi-solid). Therefore, it increases the damping force, which helps to make the suspension stiffer. After the oscillation gets down, ECU de-energizes the coil. So the magnetic field generated is decreased gradually and recovers the fluid to its normal state consequently by randomizing the iron particles. It happens whenever the continuous variable oscillation takes place in real-time conditions. The technology sounds great, but there is a lag on the magnetic field shut off while de-energize. So proper damping cannot be applicable on required conditions. It takes around 25 milliseconds for complete damping.

To overcome this issue, BWI (Beijing West Industries), a supplier of brake and suspension systems, China, bought the next generation MagneRide suspension with two electric coils, which have wound in opposite directions inside the damping piston instead of one. While energizing these coils, both generate a magnetic field in opposite directions, which builds the magnetic field stronger. While de-energize, both opposite magnetic field gets cancel each other very quickly. It takes only 13 milliseconds for complete damping.

 

MagneRide's technology brings the suspension soft to hard and vise versa almost spontaneously as per the road conditions. MagneRide has been used in many cars, like Ford Mustang, General Motors Cadillac, Chevrolet, Range Rover, and so on. Continuous variable damping in dynamic situations is a bigger advantage and expensive than the conventional type is a bigger disadvantage.
