The disclosure relates to an electrohydraulic drive system comprising an electric motor and a fluid pump that can be driven by the electric motor via an output shaft and has a rotor, which is rotatably guided in a stator surrounded by a housing of the electric motor, and a pump housing. A damping block is inserted between the electric motor housing and the pump housing in order to reduce noise emissions, said damping block being made of a metal material in a solid construction, and the output shaft passes through the damping block, said output shaft being guided in the damping block in a bearing point which is completely surrounded by the damping block and the bearing shell of which is directly supported against the damping block.
