Document Type and Number:
WIPO Patent Application WO/2022/110840
Kind Code:
A1
Abstract:
The present application relates to the technical field of engineering vehicles. Disclosed are an apparatus and method for actively reducing action impact of an excavator, and an excavator. The method comprises: collecting a boom inclination angle, an arm inclination angle, a bucket inclination angle, and state information of an operation lever of an excavator; determining operating information of the operation lever, and determining whether the boom inclination angle, the arm inclination angle and the bucket inclination angle are within a set interval; and controlling, according to the determination result, the running state of an electric control main valve and a main pump of the excavator. Impact and vibration generated during operation can be reduced, thus reducing the failure rate, and improving the service life and the working efficiency.
