Steering rocker arms are hingedly connected to both sides of the steering cylinder, and the steering rocker arms on both sides are respectively connected to steering knuckles provided on the steering kingpin housing. A front axle bracket for connecting to the engine is connected to the upper portion of the steering cylinder.

[0005] The connection end between the steering rocker arm and the octagonal axle housing is provided with a line position for adjusting the steering angle;

[0006] A bearing is provided at the inner end of the windshield oil inlet on the octagonal bridge housing.

[0007] Furthermore, the front drive axle of the improved Ningbo tractor has a large steering angle of up to 50 degrees.

[0008] Beneficial effects of the utility model:

[0009] 1. The linear design of the adjustable steering angle makes steering more flexible and precise, improving the tractor's handling performance;

[0010] 2. Large-angle steering capability (50 degrees) enhances the tractor's adaptability in complex farmland environments and improves operating efficiency;

[0011] 3. The bearing design in the windshield oil inlet makes it maintenance-free. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a structural diagram of the front drive axle of an improved Ningbo type tractor of the present utility model;

[0013] Figure 2 This is a structural diagram of the terminal assembly in this utility model. DETAILED DESCRIPTION

[0014] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0015] In the description of the embodiments of the present invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the product of the utility model is usually placed when in use. It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0016] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0017] In the description of the embodiments of the present invention, “a plurality of” means at least 2.

[0018] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0019] Embodiment: The improved Ningbo tractor front drive axle proposed in the present invention comprises a reinforced octagonal axle housing 1, a rocking support 2 and a steering cylinder 3 located above the rocking support 2, with steering rocker arms 4 hingedly connected to both sides of the steering cylinder 3.

The characteristics of the present invention are:

[0020] The connection end between the steering rocker arm 4 and the octagonal axle housing 1 is provided with a line position for adjusting the steering angle. By adjusting the line position 100, the steering angle can be precisely controlled to improve the flexibility and accuracy of steering.

[0021] A bearing 200 is provided at the inner end of the windshield oil inlet on the octagonal bridge housing 1. This design makes this part maintenance-free.

[0022] Furthermore, the improved Ningbo tractor's front drive axle has a large steering angle of 50 degrees, which significantly improves the tractor's ability to operate in narrow or complex terrain compared to traditional designs.

[0023] In summary, the improved Ningbo-type tractor front drive axle provided by the utility model realizes the adjustable steering angle and the improvement of the quality of the windshield oil inlet by optimizing the steering mechanism design and maintenance-free design, which significantly improves the steering flexibility and load-bearing capacity of the tractor and enhances the adaptability of the tractor in complex farmland environments.

[0024] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto.
