1：What is it?
The eROT Suspension System (Electromechanical Rotary Damper) is a suspension system that converts the kinetic energy generated by wheel vibrations into electrical energy for storage and use.
2：Advantages:
Energy-saving capability: Vehicles equipped with the eROT Suspension System can convert the kinetic energy generated by driving on bumpy roads into electrical energy. This energy is transmitted to a generator through gear drive and stored in a battery, thereby increasing energy utilization efficiency.
Higher space utilization: The eROT system replaces traditional shock absorber cores with electromechanical dampers, eliminating the need for hydraulic devices for cushioning while still achieving compression, rebound, and vibration filtering. Compared to traditional longitudinal suspension structures, this design saves space and improves interior space.
3：Did you know?
The eROT Suspension System is adjustable. It can independently adjust the compression and rebound rates of the shock absorbers to adapt to various road conditions, ensuring vehicle stability and passenger comfort.
Energy recovery is not limited to bumpy roads but also occurs during acceleration, braking, and cornering.
According to calculations, the eROT Suspension System can recover as little as 3W of energy on smooth roads and up to 613W on extremely bumpy roads. In simulated driving conditions, the average power recovery ranges from 100W to 150W. When applied to hybrid vehicles, it can save approximately 0.7 liters of fuel per hundred kilometers.
4：Principle:
The eROT Suspension System replaces traditional hydraulic shock absorbers with electromechanical rotary dampers. Its main components include control arms, a gear assembly, an alternator, and a 48V battery pack. Unlike traditional hydraulic dampers, which convert the kinetic energy of wheel vibrations into heat energy and dissipate it through a metal housing, the eROT Suspension System utilizes specially designed control arms to collect the kinetic energy generated during vibrations. This energy is then directed into the gear assembly, which converts the vertical motion into rotary motion. The rotary motion is transmitted to an alternator through a transmission device, ultimately converting the kinetic energy into electrical energy and storing it in the 48V battery pack.
