Vibracoustic: Air springs increase the range of the Hongqi E-SUV
Freudenberg subsidiary Vibracoustic has supplied the air springs for the front and rear axles as well as hydro suspension mounts for the new, fully electric SUV Hongqi E-HS9, the luxury subsidiary of Chinese car manufacturer FAW. The fully electric premium SUV has been available on the Chinese market since the end of 2020. The NVH (Noise, Vibration, Harshness) experts from Baden had already supplied parts in the past for the premium SUV Hongqi HS7 and the luxury sedan Hongqi H9. According to the manufacturer, the air springs are processed with an innovative welding technology that allows the use of both plastic and aluminum for the upper air spring pot. This leads to increased design flexibility and a reduced overall weight.
The air suspension not only enhances driving comfort and dynamics, but also efficiency and effectiveness. The suspension can lower the vehicle at high speeds, thereby improving aerodynamics and increasing range. Additionally, the technology can optimize the airflow under the vehicle, contributing to better passive battery cooling in electric vehicles, the provider clarifies. Furthermore, the E-HS9 is equipped with hydro chassis mounts from the supplier, which help improve driving behavior and safety and reduce unwanted vibrations.
