Abstract
A hydrostatic travel drive includes a hydraulic pump that is arranged in a hydraulic circuit with two pairs of hydraulic motors. To prevent a pressure build-up between the hydraulic motors of a hydraulic motor pair on steering while stationary, a valve device is configured to set a pressure relief to a working line or to low pressure. A mobile device includes the hydrostatic travel drive.
