A few steering systems have eliminated the traditional steering trapezoidal mechanism, allowing the load transmission between the left and right wheel steering mechanisms to remain relatively independent. This effectively improves the stress distribution and reliability of the steering system, but the transmission structure remains complex, making it difficult to control and resulting in low reliability.

[0026] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0032] This utility model provides a steering device for use in vehicles, such as tour buses, etc.

[0033] like Figures 1-6 As shown, a steering device includes a motor 1, an axle 2, a tire 3, a first angle sensor 7, a second angle sensor 9, and a guide mechanism 4. The output shaft of the motor 1 is connected to the middle of the axle 2, and the two ends of the axle 2 are hinged to the tire 3. The first angle sensor 7 is located on the axle 2 to detect the real-time position of the tire 3, and the second angle sensor 9 is located on the guide mechanism 4 to detect the angle change of the guide mechanism 4.

[0034] Motor 1 serves as the power source for the steering system, with its output shaft fixedly connected to the center of axle 2. This arrangement allows motor 1 to drive axle 2, enabling the tires 3 at both ends of axle 2 to steer synchronously. Both ends of axle 2 are hinged to the tires 3. This hinged design allows the tires 3 to rotate freely within a certain range to accommodate different steering angles. A first angle sensor 7 is mounted on axle 2 to detect the real-time position of the tires 3. Simultaneously, a second angle sensor 9 is mounted on a guide mechanism 4 to detect changes in the angle of the guide mechanism 4. The first and second angle sensors 7 and 9 are connected to the vehicle's control system via cable or wireless connection. When a turn is required, the second angle sensor 9 feeds back the turning angle to the vehicle's control system, while the first angle sensor 7 also feeds back the real-time position of the tires 3. The control system uses this data to control axle 2, thereby steering the tires 3.

[0035] This invention eliminates the complex mechanical transmission structure. It detects the steering angle using a first angle sensor 7 and a second angle sensor 9, and feeds the results back to the control system. The control system then automatically controls the wheel steering. The structure is simple, easy to control, and highly reliable.

[0036] like Figure 2 As shown, the steering device also includes a first mounting bracket 6, which is located on the axle 2 near the inner side of the tire 3, and a first angle sensor 7 is located on the first mounting bracket 6.

[0037] The first mounting bracket 6 serves as a support structure for the installation of the first angle sensor 7, providing a stable mounting platform for the installation of the first angle sensor 7. The mounting position is located on the inner side of the axle 2 near the tire 3, which can effectively reduce the interference of the external environment on the first angle sensor 7, while ensuring that the sensor can accurately detect the angle change of the tire 3.

[0038] The first angle sensor 7 is fixed on the first mounting bracket 6. The installation method can be screws, clips or welding to ensure that the first angle sensor 7 will not loosen or shift due to vibration or impact during use.

[0039] like Figure 4 As shown, the axle 2 includes an axle body 21, two steering actuators 22 and two rotating lugs 23. The two steering actuators 22 are arranged symmetrically on the left and right, and are parallel to the axle body 21. One end of the two steering actuators 22 is connected to the middle position of the axle body 21. One end of the two rotating lugs 23 is hinged to the other end of the two steering actuators 22 respectively. The other end of the two rotating lugs 23 is connected to the tire 3. The first mounting bracket 6 is provided on the axle body 21 and the rotating lugs 23.

[0040] The axle body 21 is typically made of high-strength materials (such as steel or aluminum alloy), possessing excellent resistance to torsion and bending. The shape and dimensions of the axle body 21 should be optimized according to the vehicle's design requirements to ensure sufficient rigidity and strength. Two steering actuators 22 are arranged symmetrically to ensure even force distribution and enhance symmetry and stability. One end of each steering actuator 22 is connected to the middle of the axle body 21; the connection can be made by welding, bolting, or other methods to ensure a strong and stable connection. One end of each of the two pivot lugs 23 is hinged to the other end of each steering actuator 22. This hinged structure allows the pivot lugs 23 to swing freely during steering, providing a greater range of motion and flexibility. The other end of each pivot lug 23 is connected to the tire 3, and a secure connection between the pivot lug 23 and the tire 3 can be ensured by fasteners (such as bolts or clamps). One end of the first mounting bracket 6 is connected to the axle body 21, and the other end is connected to the pivot lug 23. A first angle sensor 7 is positioned at the end of the first mounting bracket 6 near the pivot lug 23. By placing the first angle sensor 7 near one end of the rotating ear 23, the motion changes of the rotating ear 23 can be captured more accurately, thereby improving the measurement accuracy of the steering angle.

[0041] It should be noted that the axle body 21 is a standard component that can be purchased directly on the market. Therefore, its internal structure and working principle will not be described in detail here.

[0042] like Figure 3As shown, the steering device also includes a second mounting bracket 8, which is located between the axle 2 and the guide mechanism 4. The second mounting bracket 8 is vertically arranged below the axle body 21. Specifically, the top of the second mounting bracket 8 is fixedly connected to the bottom of the axle body 21, and the bottom of the second mounting bracket 8 is fixedly connected to the guide mechanism 4.

[0043] The second mounting bracket 8 is vertically arranged below the axle body 21, precisely between the axle 2 and the guide mechanism 4. This arrangement optimally supports the guide mechanism 4 using gravity and structural strength, ensuring its stability and precision during steering. The second mounting bracket 8 is securely connected to the axle body 21 by welding, bolting, or other mechanical connections.

[0044] The second angle sensor 9 is mounted on the second mounting bracket 8. The second angle sensor 9 can be fixed to the second mounting bracket 8 by means of bolts, clips, etc. Typically, the second angle sensor 9 is placed in the optimal position that can effectively detect the movement angle of the guide mechanism 4.

[0045] In one embodiment, the second mounting bracket 8 is provided with a groove, and the second angle sensor 9 is disposed in the groove.

[0046] In this embodiment, the second mounting bracket 8 is generally a trapezoidal structure that is wider at the top and narrower at the bottom. A groove is provided at the center of the bottom of the second mounting bracket 8. When the guide mechanism 4 is connected to the bottom of the second mounting bracket 8, the second angle sensor 9 is essentially enclosed in the groove, which can protect it and prevent collisions. Moreover, the position of the second angle sensor 9 in the groove is exactly aligned with the movement direction of the guide mechanism 4, ensuring the accuracy of the detection.

[0047] like Figure 5 and Figure 6As shown, the guide mechanism 4 includes a slewing bearing 41, a steering fork 42, a deflector 43, and a guide wheel assembly. The outer ring of the slewing bearing 41 is fixedly connected to the bottom of the second mounting bracket 8, and the inner ring of the slewing bearing 41 is fixedly connected to one end of the steering fork 42. The other end of the steering fork 42 is hinged to one end of the deflector 43, and the axis of the hinge shaft is parallel to the axis of the axle body 21. The other end of the deflector 43 is hinged to the guide wheel assembly. The guide wheel assembly includes a first wheel frame 44, a second wheel frame 45, a third wheel frame 46, an upper guide wheel 47, and a lower guide wheel 48. The first wheel frame 44 is a hollow structure, and the I-beam guide is arranged inside the first wheel frame 44. The second wheel frame 45 and the third wheel frame 46 are fixedly connected to the left and right sides of the interior of the first wheel frame 44, respectively. The first wheel frame 44 has upper guide wheels 47 symmetrically arranged above the upper flange of the I-beam guide. The third wheel frame 46 has lower guide wheels 48 symmetrically arranged below the upper flange of the I-beam guide. The third wheel frame 46 has side guide wheels 49 symmetrically arranged on both sides of the web of the I-beam guide.

[0048] The outer ring of the slewing bearing 41 is fixed to the bottom of the second mounting bracket 8, and the inner ring is connected to one end of the steering fork 42. This mounting method provides rotational flexibility while ensuring structural stability and strength. The hinge between the steering fork 42 and the deflector 43 allows the steering fork 42 to have a certain deflection angle when steering, thereby improving steering flexibility and response speed. The multi-wheel design of the guide wheel assembly enables the guide mechanism 4 to effectively guide and support in multiple dimensions. Through the configuration of guide wheels in different directions, the vehicle can maintain stability during movement, reducing roll and vibration.

[0049] like Figure 1 As shown, the steering device also includes a drive shaft 5. The output shaft of the motor 1 is hinged to one end of the drive shaft 5 along its axial direction, and the other end of the drive shaft 5 is hinged to the middle of the axle 2.

[0050] As a key component for power transmission, driveshaft 5 transmits the torque output by motor 1 to axle 2. The other end of driveshaft 5 is connected to the middle of axle 2 via a hinge, which allows axle 2 to make small left and right movements during steering to absorb the impact from uneven road surfaces.

[0051] By setting the drive shaft 5, stress concentration during torque transmission can be effectively dispersed and buffered, reducing the risk of failure due to excessive wear.

[0052] This utility model embodiment also provides a sightseeing vehicle, including the steering device described above. Apart from the steering device, the remaining structure of the sightseeing vehicle is the same as that in the prior art; therefore, the remaining structure will not be described in detail here.

[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
