置。 A vehicle body that constitutes the main vibration system together with the front wheels and rear wheels,
A working machine that is supported by a blade lift cylinder between the front and rear wheels and constitutes a sub-vibration system, an accelerometer that detects the running vibration of the vehicle body, an electromagnetic switching valve installed in the hydraulic circuit of the blade lift cylinder, and an electromagnetic switching system. and a controller that controls the valve, and the controller generates vibration having an opposite phase vibration waveform in the sub-vibration system based on the vibration waveform detected by the accelerometer, thereby suppressing running vibration of the vehicle body. Active vibration suppression device for motor graders.
