Alternative Energy Sources Hybrid Transport Drives Today’s commercial vehicles are challenged to reduce emissions and operate with greater energy efficiency – and Rexroth hydraulic hybrid drive systems offer proven, cost-effective platforms that vehicle builders and fleet operators can easily adapt to their needs. Through innovative applications of electrohydraulic controls and hydraulic storage systems, Rexroth hydrostatic regenerative braking systems and hydrostatic fan drives make it possible to minimize energy that is typically lost in operating commercial vehicles. Typical examples include engine cooling and braking energy. More on Rexroth hybrid transport drive solutions. Hybrid transport drive case study Hydraulic hybrid technology tested in NYC refuse trucks — New York City’s Department of Sanitation has begun a 9-12 month in-field evaluation of Bosch Rexroth's Hydrostatic Regenerative Braking (HRB) system in refuse trucks – to assess potential fuel economy and emissions reductions the hybrid drive system offers under real-world conditions.
