| Abstract: | The hydraulic driving scheme was used in a push pulling air cushion platform. The double pump synchronal oil loop of the push pulling mechanism and the reversed synchronal oil loop of the anchoring mechanism of the hydraulic system ensure stability in the straightaway working state and controlability in the turnaround working state. This hydraulic system was equipped with a computer measurement and control device. The PWM control method was used in the hydraulic system, so that the running speed and the turning radius could be adjusted steplessly and smoothly. By using this design scheme the platform had a good maneuverability. This design scheme has many notable advantages such as simple structure, small weight, high driving efficiency, little running resistance and good adaptability to the road surface, and it is a novel and practical one in the vehicle driving field. The composition of the system and its working principle are also described in the paper. |
