Walking and vibrating system for mechanically driving road roller and control method of walking and vibrating system
The walking and vibrating system comprises an engine, an electric proportioning pump, a vibrating motor, an engine ECU (electronic control unit), a controller and a frequency sensor, the engine ECU is connected with the engine, an output port of the engine is connected with the electric proportioning pump, the electric proportioning pump is connected with a main oil port of the vibrating motor, and the frequency sensor is connected with the controller. The controller is connected with an electromagnetic valve on the electric proportioning pump, and the controller is connected with the engine ECU and the frequency sensor at the same time; according to the control method, when the rotating speed of the engine changes, the frequency sensor detects the change of the rotating speed of the vibration motor, a signal is transmitted to the controller, the displacement of the electric proportional pump is adjusted through the output of the controller, and therefore the change of the rotating speed of the vibration motor is achieved. While the vehicle speed is changed, the displacement of the electric proportioning pump can be automatically adjusted, and the vibration frequency is kept unchanged; and the compaction efficiency is improved while the compaction quality is ensured.
本发明公开了一种用于机械驱动压路机的行走、振动系统，包括发动机、电比例泵、振动马达、发动机ECU、控制器和频率传感器，发动机ECU与发动机连接，发动机的输出口连接电比例泵，电比例泵与振动马达的主油口相连，控制器与电比例泵上的电磁阀连接，控制器同时与发动机ECU、频率传感器连接；其控制方法，当发动机的转速变化时，频率传感器检测到振动马达转速的变化，信号传递到控制器，通过控制器的输出调整电比例泵的排量，从而实现振动马达转速的变化。本发明能够在实现车速变化的同时，自动调整电比例泵的排量，保持振动频率不变；在保证压实质量的同时提高压实效率。
