Suspension System Using Energy Regeneration

  • Sunil Kumar Gaur

Abstract

Vehicles are developing within the direction of energy-saving and electrification. Suspension has been widely developed within the field of vehicles as a key component. Traditional hydraulic energy-supply suspensions dissipate vibration energy as waste heat to suppress vibration. This a part of the energy is especially generated by the vehicle engine. So as to effectively utilize the energy of this part, the energy-regenerative suspension with energy recovery converts the vibrational energy into electricity because the vehicle’s energy supply equipment. This text reviews the hydraulically powered suspension of vehicles with energy recovery. The importance of such suspension in vehicle energy recovery is analyzed. The most categories of energy-regenerative suspension are illustrated from different energy recovery methods, and therefore the research status of hydraulic energy-regenerative suspension is comprehensively analyzed. Important factors that affect the shock-absorbing and regenerative characteristics of the suspension are studied. Additionally, some unresolved challenges also are proposed, which provides a reference value for the event of energy-regenerative suspension systems for hybrid new energy vehicles.
