[0006] To solve the above-mentioned technical problems, the articulated structure large wheeled tractor provided by this utility model includes: a frame, the frame including a front frame, a rear frame and an upper connecting plate, the lower hinge point of the front frame and the lower hinge point of the rear frame are connected by a joint bearing and a lower pin, and the upper hinge point of the front frame and the upper hinge point of the rear frame are connected by the upper connecting plate.

[0007] Preferably, it further includes an engine, a clutch, a transmission, a front axle, a transfer case, a body panel, a rear axle, and a lifting device, wherein the engine, the clutch, the transmission, the front axle, and the transfer case are mounted on the front frame, and the body panel, the rear axle, and the lifting device are mounted on the rear frame.

[0008] Preferably, the engine, clutch, and gearbox are rigidly connected in sequence to form a whole.

[0009] Preferably, the gearbox and the transfer case, the transfer case and the front axle and the rear axle are connected by three drive shafts to output the engine's power.

[0010] Compared with related technologies, the articulated structure large wheeled tractor provided by this utility model has the following advantages:

[0011] This utility model provides a large wheeled tractor with an articulated structure. Its modular design allows for flexible layout and convenient maintenance, facilitating the use of mature technologies from the heavy truck, construction machinery, and tractor industries. This expands the product range towards higher horsepower and fills a domestic gap. The frame is a full-frame design with higher load-bearing strength, consisting of a front frame, rear frame, upper connecting plate, tapered roller bearings, and spherical plain bearings (first and second spherical plain bearings). Two steering cylinders enable on-the-spot steering, improving the maneuverability of the large wheeled tractor. The use of heavy truck engines, clutches, gearboxes, and drive shafts, as well as construction machinery front and rear axles, ensures high reliability and facilitates production organization and after-sales service. It can fully utilize technologies from other fields to expand the product portfolio, developing products with over 400 horsepower, and supporting large composite implements, thereby enhancing the mechanization and intelligence of agricultural operations.
