The invention relates to a drive (1) with an energy store device and to a method for storing braking energy. A drive (1) has an energy store device having a hydrostatic piston machine (9) and a storage element (11) which is connected thereto. Arranged in a high-pressure storage line (10) between the piston machine (9) and the storage element (11) is an adjustable throttle point (15). During braking, the adjustable throttle point (15) is adjusted as a function of a determined demanded braking torque. The pressure medium is fed by the hydrostatic piston machine (9) via the adjustable throttle point (15) into the storage element (11).
L'invention concerne un système d'entraînement (1) muni d'un dispositif d'accumulation d'énergie et un procédé pour accumuler de l'énergie de freinage. Le dispositif d'accumulation d'énergie du système d'entraînement (1) selon l'invention est composé d'une machine à piston (9) hydrostatique et d'un élément d'accumulation (11) relié à celle-ci. Dans une conduite d'accumulation à haute pression (10) est disposée, entre la machine à piston (9) et l'élément d'accumulation (11), un poste d'étranglement (15) réglable. Pendant le freinage, le poste d'étranglement (15) réglable est ajusté en fonction d'un couple de freinage sollicité par calcul. Le fluide de pression est refoulé par la machine à piston (9) hydrostatique, à travers le poste d'étranglement (15), dans l'élément d'accumulation (11).
