Problems solved by technology

[0002] In the prior art, the articulation mechanism used for the motor grader is directly controlled by the operating device and the hydraulic system, and cannot be adjusted according to the differential lock and gear position information, resulting in the potential safety hazard of tipping over when the motor grader is hinged at a higher gear. , and will accelerate the wear of the tires; in addition, there is no automatic control method for the articulation steering of the motor grader in the prior art, which causes the driver to manually operate the articulation steering frequently in a narrow area, which brings great inconvenience. Increased the burden of manual work, low efficiency, long work cycle and unsafe

Abstract

The invention relates to a grader articulated steering mechanism and a control method thereof, and belongs to the technical field of engineering machinery. The grader articulated steering mechanism comprises an articulated device, a hydraulic device and a control device, wherein the articulated device comprises a front frame and a rear frame which are rotationally connected through a first rotating shaft; the hydraulic device comprises a hydraulic oil tank, a hydraulic pump, a hydraulic valve position control unit and articulated oil cylinders; and the control device comprises a controller, anautomatic control switch, an operating handle, a gear controller, a front wheel steering sensor and a rear axle differential lock. The grader articulated steering mechanism and the control method thereof have the beneficial effects of giving full consideration to the correlation of the articulated device with the differential lock and vehicle gear information, achieving automatic control of articulated steering, reducing potential safety hazards during articulated steering, and providing convenience for a driver to perform frequent articulated steering in a narrow area.
