For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be arbitrarily combined with each other.
In the related art, in general, when a four-wheel drive vehicle is steering, the steering angles of tires on both sides of a differential are the same. However, when the steering is performed at a small angle, the steering radius of the tire positioned at the steering outer ring is far larger than that of the tire positioned at the steering inner ring. If the steering angles of the tires at the two sides are the same, the tires positioned at the steering outer ring are easy to be subjected to the condition of abrasion removal during steering, so that the tire gripping force of the outer ring is insufficient, and meanwhile, the abrasion of the tire at the inner ring is aggravated.
Because the road area that agricultural machinery can be used for driving and turning in the farm field is smaller, simultaneously, the ground in farmland is softer, therefore, in the operation process of agricultural machinery, the above-mentioned condition is more outstanding.
As shown in fig. 1, a left transmission assembly and a right transmission assembly are respectively arranged on two sides of the differential in a transmission way, and two ends of the hydraulic cylinder are respectively hinged with the left transmission assembly and the right transmission assembly. Under the setting condition, when steering, the steering angles of the left transmission assembly and the right transmission assembly are the same, so that the situation that the tire of the steering outer ring is abraded can be caused, and meanwhile, the abrasion of the tire of the inner ring can be increased.
Based on this, the exemplary embodiment of the application provides a driving steering axle, which is provided with a left hydraulic cylinder and a right hydraulic cylinder, wherein the left hydraulic cylinder and the right hydraulic cylinder can respectively drive a left transmission assembly and a right transmission assembly to rotate at different angles when steering, so as to drive a left tire and a right tire to rotate at different angles, thereby preventing the outer tire from being worn off when steering, and simultaneously reducing the abrasion of the inner tire.

Power is transmitted through the differential 10 to the left and right drive assemblies 20 and 30 on either side of the differential 10, which in turn drives the tires 80 on either side.
With continued reference to fig. 2, the steering axle further includes a left hydraulic cylinder 50 and a right hydraulic cylinder 60, wherein the fixed end of the left hydraulic cylinder 50 is hinged to the differential 10, the extended end of the left hydraulic cylinder 50 is hinged to the left transmission assembly 20, and two ends of the left hydraulic cylinder 50 are hinged to the differential 10 and the left transmission assembly 20 through hinge brackets, respectively. The fixed end of the right hydraulic cylinder 60 is hinged with the differential 10, the extending end of the right hydraulic cylinder 60 is hinged with the right transmission assembly 30, and two ends of the right left hydraulic cylinder 50 are respectively hinged with the differential 10 and the right transmission assembly 30 through hinged brackets. When steering, the left hydraulic cylinder 50 and the right hydraulic cylinder 60 can respectively drive the left transmission assembly 20 and the right transmission assembly 30 to rotate at different angles, so as to drive the left tire 80 and the right tire 80 to rotate at different angles, thereby preventing the outer tire 80 from being worn off during steering, and simultaneously reducing the abrasion of the inner tire 80.
In one embodiment, the right transmission assembly 30 includes a fixed gear box 301 in transmission connection with the differential 10, a movable gear box 302 is disposed below the fixed gear box 301, and the extending end of the right hydraulic cylinder 60 is hinged with the movable gear box 302.
Similarly, the left transmission assembly 20 also comprises a fixed gear box 301 in transmission connection with the differential 10, a movable gear box 302 is also arranged below the fixed gear box 301, and the extending end of the left hydraulic cylinder 50 is hinged with the movable gear box 302.

The lower end of the second transmission shaft 3012 extends downwards to be located in the movable gear box 302, the movable gear box 302 comprises a second shell, a third transmission shaft 3022 which is perpendicular to the second transmission shaft 3012 is arranged in the movable gear box 302, namely the axial direction of the second transmission shaft 3012 is perpendicular to the axial direction of the third transmission shaft 3022, the second transmission shaft 3012 is in transmission connection with the third transmission shaft 3022 through a second bevel gear pair 3021, and the third transmission shaft 3022 is in transmission connection with the hub 40.

In one embodiment, the steering axle further includes a damper 70, the damper 70 is disposed on the other side of the differential 10, facing away from the left and right hydraulic cylinders 50 and 60, and a spring is disposed inside the damper 70. The two ends of the damper 70 are fixedly disposed on the two movable gearboxes 302, respectively. The damper 70 can reduce shock such as vibration during running and has a balancing function.
In one embodiment, as shown in fig. 4, when the steering is performed at a small angle, the thrust force of the left and right cylinders 50 and 60 is smaller than the pressure of the springs, and at this time, the damper 70 plays a role of balancing so that the steering angle of the tire 80 is uniform. At this time, the positions of the piston rods of the left hydraulic cylinder 50 and the right hydraulic cylinder 60 are the same, and the oil ports of the left hydraulic cylinder 50 and the right hydraulic cylinder 60 are communicated, so that the piston stroke of the oil cylinder is adjusted within a certain rotation angle.
