The power supply is the main obstacle to developing new energy driverless buses while assuming the absence of battery technology advances. This paper proposes a new energy regenerative shock absorber to capture the wasted kinetic energy of the vehicle suspension system and produces electrical power.
The mechanism converts two-way motion into one-way rotation. Output power regenerated by the shock absorber is stored in a supercapacitor. Maximum and average efficiencies are 65.02% and 39.46%, respectively. The findings are prolific for powering auxiliary devices of new energy driverless buses.
A prototype of this regenerative shock absorber was fabricated. Then the power generation performance of the regenerative shock absorber was evaluated by theoretical analysis, simulation results, and bench test. According to theoretical analysis, the system can generate electricity effectively.
In theory, by regenerating braking energy, maximum fuel efficiency can be increased by 30%, and efficiency can be further improved by 10% by recovering the vibration energy in suspension systems . Energy regenerative shock absorber (ERSAs) that scavenge vibration energy are considered one of the most promising methods.
The real-world application of the proposed shock absorber on NEDB regenerated about 17 W of power.
In this paper, a new energy regenerative shock absorber (ERSA) based on a tree-like mechanism is proposed. The vibration energy lost in the suspension system can be regenerated by the designed ERSA.

Through the damping of the rubber, a high degree of energy absorption is achieved. The rubber is stiffer under dynamic conditions compared to static or pseudo-static loading; hence more energy is absorbed for a given deformation. The shock buffer type ANB is used to effectively limit the movement of equipment or machine components. These ...
