“…Indirect-drive RSA are equipped with rotary motor which requires the conversion of the linear motion of the shock absorber to rotary motion of the motor. The conversion can be realized through hydraulic pipe [11] [12] [13], rack and pinion mechanism [14,15,16,17], arm-teeth mechanism [18,19], ball screws mechanism [20,21,22,23,24,25,26] and etc. During the conversion process the motor rotation speed is always amplified.…”

“…As the movement in the vehicle suspensions is translational, the generation of a rotationally variable magnetic field requires a mechanism that converts translation into a rotation. These are well-known systems: rack-pinion [21][22][23], hydraulic [24][25][26][27][28][29], ball-screw [30][31][32][33], and some more exotic such as the "Linkage mechanism" [34], "Two-Leg motion" [35], or using flywheel drive [36]. All these systems have their own equivalent inertias, backlashes, and frictions affecting the dynamic behavior of the shock absorber and, therefore, the vehicle.…”

Numerous authors have studied Energy Harvesting Shock Absorbers (EHSA) over the last decade, proposing different designs with diverse geometries, parameters, and components. This article analyzes the energy recovery potential of two types of rotational EHSA, those that use ball-screw and those based on cable transmission. This paper presents the design, manufacturing and mathematical modeling of both options as well as the estimation of the potential power recovery with both technologies. Two types of vehicles are used as references, each one with the characteristic curves of their shock absorbers. Results are presented for different vehicle speeds and road types. Finally, some qualitative characteristics of both EHSAs are detailed to be taken into consideration for their possible use in vehicle suspension.

“…When the regenerative shock absorber system was subjected to a large motion load, it was prone to failure. To achieve motion conversion, Zhang [33] proposed a new indirect-drive regenerative damper system that uses the arm gear mechanism to achieve linear transformation of rotational motion and increase energy-harvesting output by increasing its input speed. Gao [34] studied the energy flow mechanism inside an active suspension system and the vibration energy caused by rough pavement.…”

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