Description

Technical Field

[0001] The present application belongs to the field of vehicle technology, and specifically, relates to a vehicle steering axle assembly and a vehicle. Background Art

[0002] In the field of vehicle manufacturing, especially in the manufacturing of industrial vehicles such as forklifts, the steering axle assembly is a key component, and its performance directly affects the stability, operability and safety of the vehicle. At present, the one-piece cast axle is widely used as the main structural form of the steering axle assembly. Although it has the advantage of low cost, it also has some problems in practical application.

[0003] First, the frame-mounted axle position of the one-piece cast bridge is fixed and cannot be flexibly adjusted according to the stability requirements of the forklift. If the position of the frame-mounted axle needs to be changed, it is usually necessary to re-open the mold, which not only increases the manufacturing cost but also prolongs the product development cycle. Secondly, for large-tonnage forklifts, the steering axle assembly needs to withstand greater loads and impact forces, so there are higher requirements for its strength and wear resistance. However, traditional cast iron materials often cannot meet the requirements of axle mounting, which to a certain extent limits the scope of use and performance improvement of the forklift.

[0043] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0044] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0045] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0046] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0047] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0048] The vehicle steering axle assembly and the vehicle provided in the embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0049] According to one embodiment of the present application, a vehicle steering axle assembly is provided, which can be applied to the front of a vehicle such as a forklift. It uses the steering knuckle on the axle to deflect the wheels at both ends at a certain angle to achieve the steering of the vehicle. In addition to bearing the vertical load of the vehicle, the vehicle steering axle assembly also bears longitudinal force and lateral force and the torque caused by these forces. These forces are mainly borne by structural components such as the front beam and the steering knuckle. In general, the main function of the vehicle steering axle assembly is to provide steering and support functions for the vehicle, while transmitting or bearing forces from different directions of the vehicle to ensure the normal driving and stability of the vehicle.

[0050] The vehicle steering axle assembly provided in the embodiment of the present application is shown in FIG. Figures 1 to 3 The vehicle steering axle assembly includes a steering axle body 1 and a frame mounting shaft 4; wherein the frame mounting shaft 4 and the steering axle body are formed separately, the frame mounting shaft 4 is connected to the steering axle body, and the frame mounting shaft 4 is used to be connected to the frame.

[0051] In the existing technology, the vehicle steering axle assembly is an integrated cast steering axle. Although it has the advantage of low cost, the position of the frame mounting shaft arranged thereon is fixed, and the frame mounting shaft needs to be connected to the vehicle frame, such as the frame of a forklift. Therefore, the height of the frame mounting shaft will affect the stability of the forklift. If the position of the frame mounting shaft is too high or too low, the position of the frame mounting shaft must be changed, which requires the vehicle steering axle assembly to be re-molded, which is costly.

[0052] The vehicle steering axle assembly provided in the embodiment of the present application has a unique and practical structural design. It is mainly composed of a steering axle body and a frame mounting shaft 4, and these two parts are not integrally formed, but are separately manufactured and then connected as needed. This design makes the position design of the frame mounting shaft 4 quite flexible, and it can be adjusted up and down according to the frame height requirements of the vehicle, such as a forklift, and then connected to the steering axle body. This makes it unnecessary to re-mold the steering axle body when facing different forklift frame connection requirements, greatly reducing production costs and shortening product development cycles. The technical solution provided in the embodiment of the present application realizes the simple adjustment of the position of the frame mounting shaft 4 on the vehicle steering axle assembly without the need to re-mold the entire vehicle steering axle assembly.

[0053] The frame mounting shaft 4 and the steering axle body can be cast separately and then connected together. Of course, the frame mounting shaft 4 and the steering axle body can be made by casting technology, but also other technology.

[0054] In addition, in the technical solution of the vehicle steering axle assembly of the embodiment of the present application, since the steering axle body and the frame mounting shaft 4 are manufactured separately and then connected, the intermediate core mold (which is related to the connection with the frame mounting shaft 4) can be eliminated in the casting of the steering axle body, which helps to reduce the mold opening cost.

[0055] The steering axle body serves as the basic structure of the entire vehicle steering axle assembly, bears most of the weight of the vehicle (such as a forklift) during driving, and ensures driving stability.

[0056] The main function of the frame mounting shaft 4 is to connect the frame and ensure a stable connection between the frame and the steering axle body. Through the connection with the frame, the frame mounting shaft 4 not only transmits various forces during vehicle driving, but also ensures the stability and safety of the vehicle during steering.

[0057] According to the vehicle steering axle assembly provided in the embodiment of the present application, the split manufacturing method reduces the production cost because there is no need to re-open the mold for each different frame installation shaft position, which greatly shortens the product development cycle and improves production efficiency.

[0058] The embodiment of the present application proposes a vehicle steering axle assembly, in which the frame mounting shaft and the steering axle body are formed by separate processing. The frame mounting shaft can not only achieve a stable connection with the frame, but also can be flexibly adjusted in position according to the connection requirements of the frame. This design makes it unnecessary to perform tedious mold opening operations on the entire steering axle body when adjusting the position of the frame mounting shaft, thereby greatly improving work efficiency and reducing manufacturing costs.

[0059] In some examples of this application, see Figure 1 The steering axle body includes a main body 1 and a mounting seat 5, and the mounting seat 5 is connected to the main body 1; the frame mounting shaft 4 and the mounting seat 5 are formed separately, and the frame mounting shaft 4 is connected to the mounting seat 5.

[0060] According to the example provided in the present application, the steering axle body includes a main body 1 and a mounting seat 5 arranged on the main body 1 , and the frame mounting shaft 4 is connected to the mounting seat 5 .

[0061] The mounting seat 5 is a part of the steering axle body, and is also processed separately from the frame mounting shaft 4 .

[0062] The mounting seat 5 is cleverly connected to the steering axle body, and its function is not only to fix the frame mounting shaft 4, but also to provide stable support for the entire vehicle steering axle assembly.

[0063] It is worth mentioning that the frame mounting shaft 4 and the steering axle body are processed separately. This design enables the frame mounting shaft 4 to be manufactured independently of the steering axle body, and then the position on the mounting seat 5 can be adjusted up and down according to the actual height requirements of the connection with the frame. This flexibility increases the freedom of vehicle design, especially for vehicles of different types and different loads, the assembly stability can be optimized by adjusting the position of the frame mounting shaft 4.

[0064] In some examples of this application, see Figure 1 and Figure 3 The frame mounting shaft 4 is welded to the middle part of the mounting seat 5 .

[0065] The connection method of welding the frame mounting shaft 4 and the mounting seat 5 is relatively simple, and the frame mounting shaft 4 can be welded to a suitable position of the mounting seat 5 as needed. At the same time, the connection method of welding can ensure the connection strength between the frame mounting shaft 4 and the mounting seat 5.

[0066] Furthermore, the frame mounting shaft 4 is welded to the middle of the mounting seat 5. First, the middle position is usually the most solid and stable part of the mounting seat 5. Welding the frame mounting shaft 4 here can ensure that the connection between the frame and the steering axle body 1 is more solid and reliable, and can withstand various forces generated by the vehicle during driving and steering. Secondly, this design also improves the stability of the vehicle. Since the frame mounting shaft 4 is located in the middle of the mounting seat 5, it can evenly distribute the weight of the frame to both sides of the steering axle body 1, making the vehicle more stable during driving and reducing the shaking and instability caused by uneven weight distribution. In addition, welding the frame mounting shaft 4 to the middle of the mounting seat 5 is also convenient for installation and adjustment. The welding position can be accurately controlled during the manufacturing process to ensure that the matching degree between the frame mounting shaft 4 and the mounting seat 5 reaches the best state.

[0067] In general, welding the frame mounting shaft 4 to the middle portion of the mounting seat 5 not only enhances the structural strength and stability of the vehicle steering axle assembly, but also simplifies the installation and adjustment process.

[0068] In some examples of this application, see Figure 2 The main body 1 includes a main body portion and assembly ends respectively arranged at both ends of the main body portion, and the mounting seat 5 is connected to the main body portion.

[0069] The body 1 is the main part of the steering axle body, and is also the main body of the vehicle steering axle assembly. It is mainly composed of a main body and an assembly end, and these two parts cooperate with each other.

[0070] The main body is the main structure of the body 1, which bears most of the weight of the vehicle and ensures the stability and safety of the vehicle during driving. It has excellent rigidity and strength, can resist various impacts and vibrations from the road, and ensure the stability of the vehicle.

[0071] The assembly ends are respectively arranged at two opposite ends of the main body, which facilitates the connection between the entire vehicle steering axle assembly and other components such as wheels.

[0072] The mounting seat 5 is connected to the main body. As a key component connecting the frame mounting shaft 4 and the body 1, the mounting seat 5 is reasonably designed and firmly installed, ensuring a tight fit between the frame mounting shaft 4 and the body 1. This connection method not only improves the structural strength of the entire steering axle assembly, but also enhances its stability and reliability.

[0073] In some examples of this application, see Figures 1 to 3 The mounting seat 5 is provided with an axle pin 10 , and the mounting seat 5 is connected to the main body of the body 1 through the axle pin 10 .

[0074] For some examples in this application, please continue to see Figures 1 to 3 The main body is provided with a mounting hole 2 matching the shaft pin 10 , and the shaft pin 10 is connected to the mounting hole 2 .

[0075] See also Figure 3 , an axle pin 10 is provided on the mounting seat 5. The main body of the body 1 is correspondingly provided with a mounting hole 2 matching the axle pin 10, see Figure 2 Through this design, the mounting seat 5 can be accurately inserted into the mounting hole 2 through the axle pin 10 , thereby achieving a stable connection with the body 1 .

[0076] Specifically, the cooperation between the axle pin 10 and the mounting hole 2 makes the connection between the mounting seat 5 and the body 1 tighter, avoiding the potential safety hazard caused by looseness or misalignment. This stable connection ensures the stability and reliability of the entire vehicle steering axle assembly during driving, and improves the overall performance of the vehicle.

[0077] The connection between the shaft pin 10 and the mounting hole 2 also simplifies the installation process. Compared with the traditional welding or bolt connection method, the design of the shaft pin 10 and the mounting hole 2 is simpler and more direct, the operation is more convenient, and the complexity and tediousness of the installation process are reduced.

[0078] In addition, the connection mode between the axle pin 10 and the mounting hole 2 is also adjustable to a certain extent. In practical applications, according to the specific requirements of vehicle assembly, the performance of the entire vehicle steering axle assembly can be fine-tuned by adjusting the position or number of the axle pin 10 and the mounting hole 2, thereby improving the flexibility and adaptability of the design.

[0079] In some examples of this application, see Figure 1The mounting seat 5 includes a top plate and two oppositely arranged side plates, and the two side plates are connected to the top plate; a part of the main body is located between the two side plates; the axle pin 10 passes through the main body 1 and the two side plates; the frame mounting shaft 4 is connected to at least one of the side plates.

[0080] See also Figure 1 The mounting seat 5 includes a top plate and two side plates arranged opposite to each other. The two side plates are connected to the top plate. The top plate and the side plates enclose a certain receiving space, which can accommodate a part of the main body. The axle pin 10 can connect the body 1 and the two side plates of the mounting seat 5 together; the frame mounting shaft 4 is connected to the two side plates. The connection between the side plate and the top plate and the frame mounting shaft can be connected by welding, for example.

[0081] In some examples of this application, see Figure 2 and Figure 3 The number of the axle pins 10 is two, the two axle pins 10 and the frame mounting shaft 4 are both arranged along the thickness direction of the main body, and the two axle pins 10 are arranged in mirror symmetry with respect to the frame mounting shaft 4 .

[0082] That is to say, the two axle pins 10 and the frame mounting shaft 4 both penetrate the main body along the thickness direction of the main body.

[0083] In order to further enhance the stability and balance of the connection between the mounting seat 5 and the body 1, two axle pins 10 are specially designed for the mounting seat 5 to connect with the body 1. The two axle pins 10 are not only arranged in the same direction as the frame mounting axis 4, but also arranged in mirror symmetry with respect to the frame mounting axis 4.

[0084] First, by symmetrically arranging two axle pins 10 on the mounting seat 5, the connection between the mounting seat 5 and the body 1 is more stable. The two axle pins 10 can jointly withstand forces and vibrations from different directions, effectively preventing loosening or misalignment of the connection parts, thereby ensuring the stability and reliability of the entire vehicle steering axle assembly.

[0085] Secondly, the axle pin 10 is arranged in the same direction as the frame mounting axis 4, which is conducive to ensuring the structural consistency and coordination of the entire vehicle steering axle assembly. This consistency can reduce stress concentration or deformation problems caused by structural differences and improve the service life and performance of the entire vehicle steering axle assembly.

[0086] Finally, the two axle pins 10 are arranged on the mounting seat 5 in a mirror-symmetrical manner with respect to the frame mounting axis 4. This symmetry makes the connection more balanced. During the driving process of the vehicle, whether it is subjected to lateral force or longitudinal force, the two axle pins can evenly share the force and maintain the stability of the connection. This balanced design helps to improve the handling and comfort of the vehicle.

[0087] It should be noted that, on the mounting seat 5, the number of the axle pins 10 includes but is not limited to two, and the number can be flexibly adjusted according to needs.

[0088] In some examples of this application, see Figure 3 An anti-rotation plate 12 is provided on the peripheral side of the mounting hole 2, and the anti-rotation plate 12 has a stop side 121. The stop side 121 of the anti-rotation plate 12 abuts against a partial edge of the shaft pin 10, and the stop side 121 can prevent the shaft pin 10 from rotating.

[0089] Specifically, the stop side 121 is a straight edge structure, the shaft pin 10 is provided with a straight edge section adapted to the stop side 121 , and the stop side 121 abuts against the straight edge section.

[0090] In order to improve the stability of the connection between the mounting seat 5 and the body 1 and prevent the mounting seat 5 from rotating relative to the body 1 during installation or use, the anti-rotation plate 12 is specially designed. This design cleverly utilizes the abutment relationship between the straight edge structure of the anti-rotation plate 12 and the edge of the shaft pin 10 to effectively limit the rotation of the mounting seat 5.

[0091] Specifically, see Figure 3 The anti-rotation plate 12 is disposed around the mounting hole 2, and its shape and size are carefully designed to ensure that the anti-rotation plate 12 can be tightly abutted against the shaft pin 10 inserted into the mounting hole 2. When the mounting seat 5 is connected to the mounting hole 2 on the body 1 through the shaft pin 10, the anti-rotation plate 12 will fit tightly with the shaft pin 10 to form effective support and restriction.

[0092] The anti-rotation plate 12 provided in the example of this application has the following technical effects:

[0093] The anti-rotation plate 12 improves the stability of the connection between the mounting seat 5 and the body 1. Since the anti-rotation plate 12 is in close contact with the axle pin 10, the mounting seat 5 is not easy to rotate when subjected to external force, thereby ensuring the overall stability of the entire vehicle steering axle assembly.

[0094] The anti-rotation plate 12 also effectively prevents the mounting seat 5 from loosening or shifting due to vibration or impact during use. This design can reduce the potential safety hazards caused by loose connection parts and improve the safety of vehicle driving.

[0095] In addition, since the abutting relationship between the anti-rotation plate 12 and the shaft pin 10 can automatically position and limit the rotation of the mounting seat 5, no additional fixing measures are required during the installation process, thereby reducing the complexity and cost of the installation.

[0096] In general, in the example of the present application, by arranging the anti-rotation plate 12 on the peripheral side of the mounting hole 2 and making it abut against the axle pin 10, the rotation of the mounting seat 5 is effectively restricted, and the stability and safety of the entire vehicle steering axle assembly are improved. This design solves the rotation problem that may exist in the traditional connection method, and provides a strong guarantee for the safe driving and stable performance of the vehicle.

[0097] In some examples of this application, see Figure 3 The anti-rotation plate 12 is connected to the mounting seat 5 via a fastener 11 .

[0098] In order to ensure that the anti-rotation plate 12 can function stably and reliably, a fastener 11 is used in the example of the present application to connect it with the mounting seat 5. The fastener 11 is, for example, a bolt. This design strengthens the connection strength between the anti-rotation plate 12 and the mounting seat 5.

[0099] Specifically, the fastener 11 is a connecting element that can tightly connect two or more parts together by means of threading, riveting or welding. In the example of the present application, the fastener 11 can be a bolt, which is used to firmly fix the anti-rotation plate 12 on the mounting seat 5. By selecting a suitable fastener type and connection method, it can be ensured that the connection between the anti-rotation plate 12 and the mounting seat 5 is both firm and reliable, and is not easy to loosen or fall off.

[0100] According to the fastener 11 connection method provided in the example of the present application, the anti-rotation plate 12 and the mounting seat 5 are connected by the fastener 11, which greatly improves the stability and reliability of the connection. Even if the vehicle is subjected to a large impact or vibration during driving, the anti-rotation plate 12 can maintain its original position and state and continue to play a role in preventing rotation.

[0101] When the fastener 11 is a bolt, the use of the fastener 11 also simplifies the installation and disassembly process. Specifically, during installation, the anti-rotation plate 12 only needs to be placed in a suitable position, and then the fastener 11 is used to fix it to the mounting seat 5. Similarly, when disassembly is required, the anti-rotation plate 12 and the mounting seat 5 can be easily separated by loosening the fastener 11.

[0102] In some examples of this application, see Figure 2 The main body includes a first crossbeam 13, a second crossbeam 14 and a connecting plate 15 connected between the first crossbeam 13 and the second crossbeam 14; both ends of the first crossbeam 13 are respectively provided with first through holes 17 along the vertical direction; both ends of the second crossbeam 14 are respectively provided with second through holes 18 along the vertical direction; wherein the first through holes 17 and the second through holes 18 located on the same side are opposite to each other, and the first through holes 17 and the second through holes 18 on the same side and one end of the adjacent connecting plate 15 constitute the assembly end, and the assembly end is used to connect the wheel hub 6, see Figure 1 .

[0103] According to this example, the specific structure and assembly method of the main body of the steering axle body 1 are described. Figure 2 The main body is mainly composed of a first crossbeam 13, a second crossbeam 14 and a connecting plate 15 connecting the two. This structure not only ensures the firmness and stability of the steering bridge body, but also facilitates assembly with other components. The structure is simple and the mold opening cost is low. The main body 1 is designed in a flat structure.

[0104] See also Figure 2 The first cross beam 13 and the second cross beam 14 are respectively arranged at the upper and lower sides of the main body, and are connected by a connecting plate 15. This combination design of the cross beam and the connecting plate enables the formed main body 1 to have sufficient rigidity and strength.

[0105] Please continue to see Figure 2 , first through holes 17 are respectively arranged along the vertical direction at both ends of the first cross beam 13, and second through holes 18 are also respectively arranged along the vertical direction at both ends of the second cross beam 14. The design of these through holes facilitates the connection with other components such as the wheel hub 6. It is particularly noteworthy that the first through hole 17 and the second through hole 18 located on the same side are opposite to each other, and they and one end of the adjacent connecting plate 15 together constitute an assembly end for assembling the wheel hub 6. This design makes the structure of the assembly end more compact and stable, and can better withstand the force and vibration from the wheel hub 6. At the same time, the assembly end is connected to the wheel hub 6, so that the entire steering axle assembly can smoothly connect the wheel to the frame to realize the driving and steering functions of the vehicle.

[0106] In some examples of this application, see Figure 1 The vehicle steering axle assembly also includes a drive component and a transmission component. The drive component and the transmission component are both arranged on the main body. The drive component is connected to the transmission component, and the transmission component is used to drive the wheel hub 6 to move.

[0107] The drive assembly and the transmission assembly are an important part of the entire vehicle steering axle assembly, and their main function is to transfer power from the drive assembly to the wheel hub 6, thereby driving the vehicle.

[0108] The driving component is the power source in the vehicle steering axle assembly and is responsible for generating power to drive the vehicle forward or backward.

[0109] The transmission assembly is a key component that connects the drive assembly and the wheel hub 6. It can effectively transmit the power generated by the drive assembly to the wheel hub 6, ensuring that the wheel hub 6 can rotate at the expected speed and direction. The design of the transmission assembly needs to take into account the efficiency, stability and reliability of power transmission to ensure that the vehicle can work normally under various driving conditions.

[0110] In the example of the present application, the drive assembly and the transmission assembly are integrated into the main body of the body 1, reducing the path and intermediate links of power transmission, thereby improving the efficiency of power transmission. The integrated design makes the maintenance and maintenance of the whole vehicle more convenient and reduces the maintenance cost. In addition, by optimizing the design of the transmission assembly, the stability and reliability of power transmission can also be improved, and the possibility of failure can be reduced.

[0111] In some examples of this application, see Figure 2 The connecting plate 15 is provided with hollow structures 16 at intervals along its length direction, and the driving assembly and the transmission assembly cover at least a portion of the hollow structures.

[0112] In the example of the present application, hollow structures 16 are arranged at intervals along the length direction of the connecting plate 15. The main purpose of this hollow design is to reduce the weight of the connecting plate 15, thereby reducing the weight of the entire steering axle assembly, which helps to improve the fuel economy and power performance of the vehicle.

[0113] The drive assembly and the transmission assembly are designed to cover at least part of the hollow structure 16, which can increase the contact area between them and the connecting plate 15 to a certain extent, thereby improving the structural rigidity and stability of the entire drive and transmission system, and at the same time facilitating the heat dissipation of the drive assembly during operation.

[0114] In some examples of this application, see Figure 1The driving assembly includes a cylinder 8 and a piston rod 9 connected to the cylinder 8. A cylinder mounting hole 3 is provided on the main body. The cylinder 8 is connected to the cylinder mounting hole 3 through a connecting piece. The two ends of the piston rod 9 extend out of the two opposite end surfaces of the cylinder 8; the transmission assembly includes two pull plates 7, which are respectively connected to the two ends of the piston rod 9, and the pull plates 7 are used to connect the wheel hub 6.

[0115] In the example of the present application, the driving assembly is mainly composed of an oil cylinder 8 and a piston rod 9 connected thereto. The oil cylinder 8 is the source of driving force, generating thrust or pulling force through hydraulic pressure or other means. The piston rod 9 serves as a bridge connecting the oil cylinder and the transmission assembly, transmitting the power generated by the oil cylinder 8 to the transmission assembly.

[0116] On the main body, a cylinder mounting hole 3 is specially provided for mounting the cylinder 8. The cylinder 8 can be firmly connected to the cylinder mounting hole 3 by means of a connecting piece, thereby ensuring the stability and reliability of the cylinder 8 during operation. This design simplifies the installation process.

[0117] The design of the piston rod 9 is also very unique, with its two ends extending out of the two opposite end surfaces of the oil cylinder 8. This design enables the piston rod to be connected to the two pull plates 7 respectively, thereby realizing two-way transmission of power. This two-way transmission method improves the efficiency of power transmission and makes the entire drive and transmission system more balanced and stable.

[0118] The transmission assembly is mainly composed of two pull plates 7, which are respectively connected to the two ends of the piston rod 9. The pull plates 7 are key components for transmission connection between the piston rod 9 and the wheel hub 6, and can effectively transmit the power of the piston rod 9 to the wheel hub 6. At the same time, each pull plate 7 is connected to the wheel hub 6 on the same side, ensuring direct and efficient transmission of power.

[0119] In the examples of this application, see Figure 1 Through the cooperation of the oil cylinder 8 and the piston rod 9, efficient power generation and transmission are achieved. The power is directly transmitted to the wheel hub 6 through the pull plate 7, which reduces intermediate links and energy losses and improves the efficiency of the entire system. In addition, this design also makes the entire steering axle assembly more compact and integrated.

[0120] In some examples of the present application, the frame mounting shaft 4 is made of steel.

[0121] In the example of the present application, steel is selected as the main manufacturing material of the frame-mounted shaft 4. This choice is intended to meet the stringent rigidity requirements of large-tonnage axles.

[0122] Steel has excellent properties, such as excellent fatigue resistance and impact resistance, so that the frame mounting shaft 4 can maintain excellent stability and reliability when subjected to heavy loads and / or complex road conditions. It not only improves the overall strength of the entire vehicle steering axle assembly and ensures the safety and stability of the vehicle during driving, but also helps to extend the service life of the vehicle steering axle assembly and reduce the risk of failure due to material fatigue.

[0123] In some examples of the present application, the body 1 is a cast one-piece component.

[0124] The one-piece casting process can ensure that the main body 1 of the steering axle has excellent integrity and continuity, and reduce potential defects or weaknesses caused by assembly.

[0125] Due to the one-piece casting, the structure of the body 1 is more compact, and the connection and assembly links between components are reduced. The one-piece casting process can ensure the uniformity and continuity of material distribution, reduce material waste, and improve material utilization. At the same time, since the welding or bolt connection processes in the assembly process are reduced, the energy consumption and emissions in the production process are also reduced. In addition, the one-piece casting design also helps to improve the fatigue resistance and impact resistance of the body 1.

[0126] According to another embodiment of the present application, a vehicle is provided, comprising the vehicle steering axle assembly as described in any one of the above items.

[0127] In some examples of the present application, the type of vehicle may be a forklift.

[0128] It should be noted that the type of vehicle is not limited to a specific vehicle, but has a wide range of applicability, which means that whether it is a passenger car, a commercial vehicle, or a special vehicle, as long as a vehicle steering axle assembly is needed, the design scheme in this application can be adopted.

[0129] In particular, the forklift mentioned in the example of this application is a typical application scenario, because the forklift needs to frequently turn and move during operation, and the performance requirements of the steering axle assembly are very high. The use of the vehicle steering axle assembly in this application can significantly improve the stability and maneuverability of the forklift.

[0130] According to actual needs, the vehicle steering axle assembly provided in the embodiment of the present application can be connected to the front wheel hub or the rear wheel hub. This design allows the vehicle to have more options in layout and configuration, and can be customized according to different usage scenarios and needs. For example, in some special cases, the rear wheels may need to have a larger steering angle or higher steering sensitivity, in which case the steering axle assembly can be connected to the rear wheel hub.
