	Modern transport vehicles and mobile machines have a high advanced functionality and quality of work. However, it is often associated with high power consumption. That is why research focused on reducing vehicle operating costs is so important. The possibilities of reduction of fuel consumption in combustion engines, which are usually the primary source of energy in many vehicles, seem to be exhausted. It came from design constraints of the combustion engine and increasingly stricter emission’s standards. That is way very popular become energy recovery system. Usually, these systems are based on an electric storage battery. Energy is capturing during braking of the vehicle and transferred to the electric motor periodically connected with the drive system. While, in the vehicles driven by hydrostatic system hydraulic energy in a similar way can be captured and stored in the hydro-pneumatic accumulator. This paper presents such solution of energy saving system based on an additional pump and hydro pneumatic accumulator build into vehicle hydrostatic drive system. Mechanical and hydraulic elements of vehicle drive system were modelled using SimulationX software. The standard drive system is comparing with the energy recuperation drive system. Tests have been conducted for assumed working cycle and several operating parameters by the use of SimulationX. Reached than 10% energy saving in one cycle, confirms the correctness of designed structure of the hydraulic energy recovery system.
