In this embodiment, during braking and/or stopping of vibration of work machine 1, traveling motor 10 and/or vibration motor 22 are loaded with a certain reverse torque to generate electric current, and then electric current is transmitted to the battery assembly through controller 20 to charge the battery assembly according to cooperation among traveling motor 10, vibration motor 22, controller 20, and the battery assembly, so as to recover energy of braking energy and/or vibration stopping energy of work machine 1.
Specifically, the working machine 1 provided in this embodiment may be a mechanical device having a vibration function, such as a road roller. As shown in fig. 3, the working machine 1 is a road roller.
According to the working machine 1 provided by the embodiment, the energy loss and waste of the working machine 1 are reduced by recovering the braking energy and/or the vibration stopping energy in the braking and/or vibration stopping process, and the energy-saving and environment-friendly performance of the working machine 1 is effectively improved.
