Hydrodynamic drive for a working machine such as a mobile crane has torque converter bridging coupling for maximum force limitation

摘要

A hydrodynamic drive for a working machine comprises a drive motor, a torque converter and switched drive, especially for machines with high drive parts such as mobile cranes. The primary coupling (16) and converter bridging coupling (WK) to limit the maximum force are in series with only one control pressure and are closed sequentially.
