AMSTERDAM - last December in compression of "Future of Electric Vehicle" or the future of electric cars in San Jose, United States, official representatives from the University of Technology of Eindhoven, the Netherlands presented the results of research institutions, namely a new type of suspension working electromagnetically.
more precisely presented is kind of suspension as a major component that is we are familiar with sock breaker or shock absorber. There is apparently the sustainable development of the university's recent progress and it make the result published into the international media.
Car test used to test this sock breaker could follow AutoRAI in Amsterdam last week. Meanwhile, the release sent by established Eindhoven University to disclose the full details about this sock breaker. Claims of the university that it increase 60 percent because of this sock breaker concerning to comfort level and stability of vehicles .
Active Suspension
Sock breaker which is not only working in electromagnetic, are also active. Exactly, it also gave a mechanical response when the car drove on the road surface is uneven. Amazingly, its active work is now controlled via computer.
Computers control the suspension based on information received from the accelerometer and other sensors on the vehicle. Based on these data, later the sock breaker is set the work back and it is only lasted a few seconds.
Actually, active suspension is not new on the car's suspension. Already many manufacturers who use them. Nevertheless, it works in a hydraulic system. Now, researchers from Eindhoven said electromagnetic response capability is much nicer. In addition, it is also assessed safer. When vehicles are moved in any condition, it remain steady and comfortable!
Electric Power
The size of elektromagnetic shock absorbers are the same as the conventional type. The system consists of passive spring and an electromagnetic actuator, the control unit and battery. Springs works quite well while magnets do passive damping. When the battery is worn out, the system works mechanically.
Electricity consumption of 500 watts or quarter energy is required by hydraulic suspension. Life time and battery life assessed will be longer. In fact, the electromagnetic properties sock breaker can be used to generate electricity. Explained also by the designers of this sock breaker still continue to develop to get the best performance, among others, increasing energy efficiency.
Further, increasing convenience reachs 60 percent. It was only tested on one wheel and tested by simulation in the laboratory. While the results of tests with the installation on two wheels, it is more stable again.
Sock breaker is now still tested. Each wheel is equipped with automatic sock breaker. It will be planned that each suspension unit (sock breaker) can interact or communicate with other units. With this condition, the coordination of movement is set more precise again.
If it is steady, the suspension was developed the University of Eindhoven who get help from the company's famous Sweden mechatronics origin, SKF. Immediately it will be patented and market it commercially!
