DRIVE CONTROL METHOD AND SYSTEM FOR OPERATING A HYDRAULIC DRIVEN WORK MACHINE |
| 摘要 |
A system and a method for operating a hydraulic driven work machine including a hydraulic travel motor having a variable displacement is provided, wherein a flow of hydraulic fluid generated by a hydraulic pump is provided to the travel motor and wherein a control valve is provided for controlling the flow of hydraulic fluid from the hydraulic pump to the travel motor. The hydraulic pump is provided with a hydraulic control depending on a load signal generated by the travel control valve and the travel motor is provided with an electric control according to a desired driving behaviour. |

1. A method for operating a hydraulic driven work machine comprising a hydraulic travel motor having a variable displacement, wherein a flow of hydraulic fluid generated by a hydraulic pump is provided to the travel motor and wherein a control valve is provided for controlling the flow of hydraulic fluid from the hydraulic pump to the travel motor in an open loop, closed centre load sensing hydraulic system, wherein the hydraulic pump is hydraulically controlled depending on a load signal generated by the travel control valve and the travel motor is electrically controlled according to a desired driving behaviour of the work machine. |
