Abstract
A hydraulic system may selectively operate in a charging mode or a driving mode, and may include a charging component, an accumulator, an input pump/motor, and an output motor. The charging component may charge an accumulator during operation in the charging mode. The accumulator may store pressure medium during operation in the charging mode, and may supply stored pressure medium to the input pump/motor during operation in the driving mode. The input pump/motor may supply pressure medium to at least the accumulator during operation in the charging mode, and may supply pressure medium to the output motor during at least operation in the driving mode. The output motor may provide output torque based on pressure medium supplied by the input pump/motor.
