Questions and Answers



1.   What is an Electromechanical (Motorized) Suspension?
Answer:   In this case, an electromechanical (Motorized) suspension uses a motor for damping road vibration.   While the standard pneumatic suspension (found on most vehicles) uses hydraulic damping.

2.   Why would you use an Active Electromechanical (Motorized) Suspension?
Answer:   It is lighter (estimated to be 30% lighter).   There are fewer parts to replace.   They are cheaper to build.   It is an active suspension.   It charges the battery under normal road conditions.   The processor is programed to keep the vehicle level.

3.   So why is lighter better?
Answer:   A lighter vehicle will move faster using less power, giving you better mileage.

4.   Why is it better to have fewer parts?
Answer:   A simpler device is easier to diagnose and fix.   The parts tend to be easier to replace and often cheaper.

5.   What is an active or passive suspension?
Answer:   An active suspension "actively" participates in the suspension of the vehicle.   In this case it adds a force to help raise or lower the vehicle to keep it balanced.   A passive suspension only adds resistance to movement.

6.   Why would a charging suspension be important?
Answer:   Any vehicle can benefit from the suspension charging.   It would lighten the load on an engine allowing more power to go to the wheels.   But the biggest benefits would be seen with electric vehicles, where a charging suspension would also increase the limited mileage and decrease the charging time of the vehicle per trip.   While a standard suspension would just create heat.

7.   What does keeping a vehicle level do?
Answer:   Because the processor is programed to keep the vehicle level, the vehicle will be less likely to dip during braking or hop during acceleration.   It would also help when steering into turns.

8.   Does it actually work?
Answer: Yes, check out the video.   It shows a sample vehicle with just a spring as the suspension (Undamped), and then with the Electromechanical (Motorized) Suspension running.   It has a weighted spring near the front to represent a passenger and it demonstrates a drop that would be the equivalent of about 10 inches for a standard car.
