Bosch Rexroth unveils regenerative braking system
Bosch Rexroth has announced a hydrostatic regenerative braking (HRB) system it said includes a hydrostatic hybrid drive to deliver reduced fuel consumption and higher performance.
According to the company, a hydraulic unit integrated in the drivetrain presses hydraulic fluid into a high-pressure reservoir when a driver presses the brake pedal, decelerating the vehicle through resistance and storing energy that otherwise would be lost.
The reservoir is electronically controlled when accelerating to release pressure and relieve the load on the diesel engine, allowing the engine to consume less fuel, generate less exhaust gases and function quieter, Rexroth said.
The company also announced its HRB parallel hydraulic hybrid system has been selected by Calstart’s Hybrid Truck Users Forum (HTUF) Refuse Working Group to test the use of hybrid vehicle technology in refuse trucks. The field tests will take place in New York City.
