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

Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only intended to illustrate the present invention more clearly

[0051] The hinge device 1; the hinge device includes a front frame 3 and a rear frame 4 that are rotatably connected by the first shaft 2;

[0054] The controller can receive automatic control switches, operating handles, gear position controllers, front wheel steering sensors, and rear axles

[0055] The front wheel steering sensor can monitor the steering state of the front wheel, and convert it into an electrical signal and transmit it to the controller;

[0060] The position sensor can detect the steering angle of the articulated device at all times and feed it back to the controller, and the position sensor can

[0065] For the convenience of use, in actual use, the operating handle is installed under the seat, and the seat is installed in the cab,

[0067] Manual control steerin...

Abstract

The invention relates to a motor grader articulated steering mechanism and a control method thereof, belonging to the technical field of engineering machinery; it includes: an articulated device; the articulated device includes a front frame and a rear frame that are rotatably connected by a first rotating shaft; a hydraulic device; a hydraulic device It includes a hydraulic oil tank, a hydraulic pump, a hydraulic valve position control group, an articulated oil cylinder, and a control device; the control device includes a controller, an automatic control switch, an operating handle, a gear position controller, a front wheel steering sensor, and a rear axle differential lock; the present invention A motor grader articulated steering mechanism and its control method are provided, which fully considers the correlation between the articulated device, differential lock and vehicle gear information, can realize the automatic control of articulated steering, and reduces the potential safety hazard during articulated steering. Frequent articulation steering provides convenience for the driver in tight areas.

Description

A motor grader hinged steering mechanism and its control method technical field The present invention relates to a kind of motor grader hinged steering mechanism and control method thereof, belong to the technical field of construction machinery. Background technique [0002] The articulation mechanism used for the motor grader in the prior art is directly controlled by the operating device and the hydraulic system, and cannot be Differential lock and gear information are adjusted, resulting in a safety risk of tipping when the motor grader is hinged in higher gears In addition, there is no automatic control method for the articulated steering of the motor grader in the prior art, and it will accelerate the wear of tires. As a result, the driver needs to manually operate in a narrow area and perform articulated steering frequently, which brings great inconvenience and aggravates the Manual work is burdened, inefficient, and the work cycle is long and unsafe.
