The invention relates to a non-hydraulic steering articulated mechanism of an electrically driven articulated all-terrain crawler, and belongs to parts of all-terrain crawlers. A corner retainer control valve is connected with a corner retainer oil cylinder, an electromotor drives a hydraulic pump to rotate, and the hydraulic pump is connected with a hydraulic oil tank and a pitching control valve; the pitching control valve is connected with pitching oil; a hinging bracket is connected with a pitching rack, a pitching cylinder is connected with the hinging bracket and the pitching rack, the pitching rack is connected with a twisting rack, the left side and right side of the corner retainer oil cylinder are arranged symmetrically and are connected with the pitching rack and the twisting rack, and the twisting rack is connected with a connecting disc. The non-hydraulic steering articulated mechanism of the electrically driven articulated all-terrain crawler has the advantages that powerconsumption of a hydraulic system is significantly reduced, the life of hydraulic system parts is prolonged, the quality of a vehicle is reduced, reliability of the vehicle is significantly improved,a driver can more easily grasp vehicle running postures, the block feeling is avoided, handing and the driving mileage of the vehicle are improved, and stability of the vehicle driving on a straightline and maintaining in the steering process is improved.
Description
technical field [0001] The invention belongs to parts of an all-terrain crawler vehicle, in particular to a steering hinge mechanism of an articulated all-terrain crawler vehicle. Background technique [0002] Articulated all-terrain crawler vehicles usually consist of 2 carriages, which are connected by a hinge mechanism in the middle. Each car has two crawlers, and the engine is arranged in the front car to provide power for the front car and drive the rear car through the transfer case and transmission shaft. The hydraulic cylinder acts on the hinge mechanism, so that there are two controllable degrees of freedom in steering and pitching between the front and rear vehicles, and a follow-up degree of freedom in torsion. This makes the articulated all-terrain crawler vehicle still have good passing ability in complex terrain. my country has a vast land area and complex terrain. There are large areas of deserts, snow fields, jungles, and mountains. There are also extreme t...
