Electronic control for the hydrostatic drive unit of a vehicle

摘要

The device (26) has an optimizing unit for optimizing traction of a set of hydrostatically-driven front and rear drive wheels (19, 20, 24, 25) by specifying a torque required at a drive unit i.e. hydraulic motor (9), depending on an application. The optimizing unit is configured so that the torque at the hydraulic motor is specified in the application-dependent manner via an intake volume requirement at the hydraulic motor. A control system (41) intervenes in the device and manually changes a performance curve i.e. wheel-load dependent performance curve, to adjust requirements for the volume.
