Hydraulic hybrids on the rise
Bosch Rexroth''s HRB system couples a hydraulic axial piston pump/motor into a mechanical drivetrain through a gearbox. When braking, the pump/motor captures kinetic energy from deceleration and converts it to hydraulic energy. This energy is stored in an accumlator and later converted back to kinetic energy to accelerate the vehicle.
