DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor fall within the protection scope of the present application.

[0039] According to a first aspect of the present application, with reference to Figures 1 to 3 The present disclosure provides a steering bridge 100, which comprises a steering output shaft 300 and at least two meshing rotating members 400 for driving the steering output shaft 300 to rotate, the steering output shaft 300 being used for controlling the steering of a wheel.

[0040] A first angle sensor 510 is used for detecting one meshing rotating member 400, and a second angle sensor 520 is used for detecting another meshing rotating member 400, the detection information of the first angle sensor 510 and the detection information of the second angle sensor 520 being used for controlling the rotation angle of the steering output shaft 300.

[0041] In this way, by means of the detection information of the first angle sensor 510 and the detection information of the second angle sensor 520, it can be determined whether the rotation angle of the steering output shaft 300 is deviated. If the rotation angle of the steering output shaft 300 is deviated, the rotation angle of the steering output shaft 300 can be adjusted according to the detection information of the first angle sensor 510 and the detection information of the second angle sensor 520, so as to compensate for the angle deviation caused by the wear of the meshing rotating member 400.

[0042] In this way, even if the meshing rotating member 400 is worn, the rotation angle of the steering output shaft 300 can be kept at a high precision by adjusting the rotation angle of the steering output shaft 300.

[0043] It is worth mentioning that the first angle sensor 510 and the second angle sensor 520 also provide redundancy protection for the steering bridge 100, that is, even if one of the first angle sensor 510 and the second angle sensor 520 fails, the other can still provide partial data support, so that the steering bridge 100 has high reliability.

[0044] Next, how to determine whether the rotation angle of the steering output shaft 300 is deviated through the detection information of the first angle sensor 510 and the detection information of the second angle sensor 520 will be introduced. In an example, in the steering bridge 100, it is assumed that the number of teeth of the two meshing rotating members 400 (the fifth meshing rotating member 400 and the sixth meshing rotating member 400) is different, for example, the fifth meshing rotating member 400 has 20 teeth, and the sixth meshing rotating member 400 has 40 teeth. Because the number of teeth is different, the rotation speed ratio of the fifth meshing rotating member 400 and the sixth meshing rotating member 400 is 1:2, that is, the fifth meshing rotating member 400 rotates one circle, and the sixth meshing rotating member 400 rotates half a circle. The first angle sensor 510 is used to detect the fifth meshing rotating member 400, and the second angle sensor 520 is used to detect the sixth meshing rotating member 400.

[0045] Under normal circumstances, the transmission relationship of the fifth meshing rotating member 400 and the sixth meshing rotating member 400 is fixed, and the rotation angles detected by the first angle sensor 510 and the second angle sensor 520 should conform to their tooth ratio. For example, when the fifth meshing rotating member 400 rotates 30°, the sixth meshing rotating member 400 should rotate 15°. If the detected angle does not conform to this relationship, for example, the fifth meshing rotating member 400 rotates 30°, but the sixth meshing rotating member 400 only rotates 14°, it indicates that the sixth meshing rotating member 400 may be worn.

[0046] By comparing the detection information of the first angle sensor 510 and the detection information of the second angle sensor 520, the existence and degree of wear can be determined.

[0047] In this way, the first angle sensor 510 and the second angle sensor 520 can monitor the wear of the meshing rotating member 400 and provide data support for adjusting the rotation angle of the steering output shaft 300, so as to compensate for the error caused by the wear of the meshing rotating member 400 and ensure the rotation accuracy of the steering output shaft 300.

[0048] In this way, the rotation angle of the steering output shaft 300 can be controlled until the sixth meshing rotating member 400 rotates to 15°, so that the accuracy of the rotation angle of the steering output shaft 300 is higher.

[0049] It is worth mentioning that in some embodiments, the steering bridge 100 further comprises a motor 200, the motor 200 drives the steering output shaft 300 to rotate through at least two meshing rotating members 400, and the motor 200 is used to control the rotation angle of the steering output shaft 300 according to the detection information of the first angle sensor 510 and the detection information of the second angle sensor 520. It can be understood that the motor 200 serves as the power source of the steering output shaft 300. However, the design is not limited to this, and in some other embodiments, the steering bridge 100 can also not be provided with the motor 200, and the power source of the steering output shaft 300 comes from other components outside the steering bridge 100, which is not limited here.

[0050] In addition, in an example, the motor 200 has a power output shaft, one meshing rotating member 400 is configured as a first meshing rotating member 410, and the other meshing rotating member 400 is configured as a second meshing rotating member 420. The first meshing rotating member 410 is sleeved on the steering output shaft 300, and the second meshing rotating member 420 is sleeved on the power output shaft. It should be noted that the first meshing rotating member 410 can be detachably connected with the steering output shaft 300, for example, the first meshing rotating member 410 can be detachably connected with the steering output shaft 300 through a spline, or the first meshing rotating member 410 can be integrally formed with the steering output shaft 300, and the second meshing rotating member 420 can be detachably connected with the power output shaft or integrally formed with the power output shaft. The first angle sensor 510 is used to detect the second meshing rotating member 420, and the second angle sensor 520 is used to detect the first meshing rotating member 410. The first meshing rotating member 410 and the second meshing rotating member 420 can be directly meshed. Of course, the first meshing rotating member 410 and the second meshing rotating member 420 can also be indirectly meshed through other meshing rotating members 400. If the first meshing rotating member 410 and the second meshing rotating member 420 are indirectly meshed together through other meshing rotating members 400, as long as one of the meshing rotating members 400 is worn, the overall wear condition of the plurality of meshing rotating members 400 on the transmission chain from the power output shaft to the steering output shaft 300 can be judged by comparing the detection information of the first angle sensor 510 and the detection information of the second angle sensor 520, so as to control the rotation angle of the steering output shaft 300, thereby improving the rotation angle of the steering output shaft 300. The accuracy can be maintained at a high level.

[0051] In addition, it is worth mentioning that the meshing rotating member 400 can be configured as a gear, can be configured as a gear shaft, or can be configured as a component in which a gear shaft and a gear are assembled together, wherein the gear is sleeved on the gear shaft. The meshing rotating member 400 can also have other structural forms, which are not limited here.

[0052] In some embodiments, the plurality of toothed rotating members 400 includes a first toothed rotating member 410, a second toothed rotating member 420, a third toothed rotating member 430, and a fourth toothed rotating member 440. The fourth toothed rotating member 440 has a gear ratio less than 1 with the third toothed rotating member 430, the third toothed rotating member 430 has a gear ratio less than 1 with the second toothed rotating member 420, and the second toothed rotating member 420 has a gear ratio less than 1 with the first toothed rotating member 410. The first toothed rotating member 410 is configured as a first helical gear 411, which is sleeved on the steering output shaft 300. The second toothed rotating member 420 includes a second gear shaft 421 and a second helical gear 422 sleeved on the second gear shaft 421. The tooth portion of the second gear shaft 421 is configured as a helical tooth portion, and the second gear shaft 421 is configured to cooperate with the first helical gear 411. The second helical gear 422 has an outer diameter greater than that of the second gear shaft 421. The third toothed rotating member 430 includes a third gear shaft 431 and a third helical gear 432 sleeved on the third gear shaft 431. The tooth portion of the third gear shaft 431 is configured as a helical tooth portion, and the third gear shaft 431 is configured to cooperate with the second helical gear 422. The third helical gear 432 has an outer diameter greater than that of the third gear shaft 431. The fourth toothed rotating member 440 is configured as a fourth gear shaft 441, and the tooth portion of the fourth gear shaft 441 is configured as a helical tooth portion. In this way, the motor 200 drives the steering output shaft 300 to rotate through the speed reduction and torque increase of the plurality of toothed rotating members 400. In addition, the first angle sensor 510 is configured to detect the first toothed rotating member 410, and the second angle sensor 520 is configured to detect the second toothed rotating member 420.

[0053] In some embodiments, the plurality of toothed rotating members 400 has a plurality of rotating axes, and the extending directions of the plurality of rotating axes are consistent and not located in the same plane. In this way, the layout of the plurality of toothed rotating members 400 is more compact. In an example, in the case that the extending directions of the plurality of rotating axes are consistent and not located in the same plane, part of the toothed rotating members 400 are arranged in sequence along the rotating axis of the hub 710. In this way, the longitudinal size of the steering axle 100 is reduced. It should be noted that the longitudinal size refers to the size of the steering axle 100 in the longitudinal direction of the vehicle when the steering axle 100 is installed on the vehicle.

[0054] Please refer to Figure 4 and Figure 5In some embodiments, the steering bridge 100 further comprises a housing 610, the housing 610 is provided with a receiving cavity 611, and the gear rotating member 400 is arranged in the receiving cavity 611. In this way, the housing 610 can provide stable support for the gear rotating member 400, ensure that it maintains a relatively precise engagement relationship during operation, and improve the stability and reliability of transmission. In addition, the receiving cavity 611 can effectively protect the gear rotating member 400, reduce the influence of foreign matter on it, thereby reducing the degree of wear of the gear rotating member 400 and prolonging the service life of the gear rotating member 400. In addition, the receiving cavity 611 can reduce the noise emitted by the gear rotating member 400 during operation, and can improve the comfort of the vehicle.

[0055] In some embodiments, the housing 610 is provided with a connecting hole for connecting the frame of the vehicle. In some embodiments, the first angle sensor 510 is connected to the housing 610 through a first flange; and / or, the second angle sensor 520 is connected to the housing 610 through a second flange. In some embodiments, the housing 610 comprises a first housing 610 and a second housing 610, which are detachably connected and used to jointly enclose the receiving cavity 611. In this way, the gear rotating member can be arranged in the receiving cavity 611.

[0056] In some embodiments, the receiving cavity 611 is used to accommodate lubricating oil, the housing 610 is provided with an avoiding hole 800 in communication with the receiving cavity 611, the steering output shaft 300 passes through the avoiding hole 800, and the steering bridge 100 further comprises a first sealing member 620 arranged in the gap between the steering output shaft 300 and the hole wall of the avoiding hole 800. In this way, the lubricating oil in the receiving cavity 611 can lubricate the gear rotating member 400 and the steering output shaft 300 in the receiving cavity 611 to reduce friction and wear and prolong the service life of the gear rotating member 400 and the steering output shaft 300. In addition, the first sealing member 620 is installed in the gap between the steering output shaft 300 and the avoiding hole 800, which can reduce the leakage of lubricating oil and prevent foreign matter from entering the inside of the housing 610, thereby reducing the degree of pollution of the lubricating oil and the degree of wear of the gear rotating member 400 and the steering output shaft 300.

[0057] In some embodiments, the steering bridge 100 further comprises a first bearing 630, and the steering output shaft 300 is rotatably connected to the housing 610 through the first bearing 630. In this way, by using the first bearing 630, the rotation of the steering output shaft 300 is smoother, and the frictional force acting on the steering output shaft 300 during rotation is significantly reduced, thereby reducing the wear of the steering output shaft 300 and prolonging the service life of the steering output shaft 300.

[0058] In some embodiments, the first bearing 630 is provided in two, and the first toothed rotating member 410 is configured as a first toothed rotating member 410, which is arranged on the steering output shaft 300 and between the two first bearings 630 in the axial direction of the steering output shaft 300. In this way, the first toothed rotating member 410 is arranged between the two first bearings 630, which can effectively improve the rigidity and stability of the steering output shaft 300. The support of the two first bearings 630 can better resist axial and radial loads, and reduce deformation or vibration caused by uneven stress. In addition, even if one of the first bearings 630 fails, the other first bearing 630 can still provide sufficient support, thereby improving the reliability and fault tolerance of the steering bridge 100.

[0059] In some embodiments, the steering bridge 100 further comprises at least one bushing 640, which is arranged between at least one of the two first bearings 630 and the first toothed rotating member 410, and the two ends of the bushing 640 respectively contact the first toothed rotating member 410 and the corresponding first bearing 630 in the axial direction of the steering output shaft 300. In this way, the bushing 640 can provide support and connection for the first toothed rotating member 410 and the first bearing 630. In addition, the bushing 640 can absorb impact to some extent, reducing the impact of these forces on the steering output shaft 300 and the first bearing 630, thereby improving the structural stability of the steering bridge 100.

[0060] In some embodiments, the first bearing 630 is configured as a tapered roller bearing. The tapered roller bearing can simultaneously bear radial and axial loads, and has high load-carrying capacity, and is particularly suitable for stable operation under high load and impact load. This feature enables the steering bridge 100 to maintain good performance under complex working conditions. The tapered roller bearing has a certain self-alignment capability and can automatically adjust the axis deviation, making the stress more uniform, thereby reducing wear and fatigue and prolonging the service life of the first bearing 630. However, the design is not limited to this, and in some other embodiments, the first bearing 630 can also be configured as other types of bearings, which are not limited here.

[0061] Please refer to Figure 6In some embodiments, the steering axle 100 comprises two wheel hubs 710, and the steering output shaft 300 is rotatably connected to the two wheel hubs 710, and one wheel hub 710 is used to connect one wheel. The two wheel hubs 710 are respectively connected to two wheels, which can better disperse the weight and load of the vehicle, improve the grip and stability of the vehicle. In addition, it also reduces the risk of vehicle rollover, especially at high speed or sharp turn, which can significantly improve the safety of the vehicle. For example, a vehicle, such as but not limited to a forklift, is provided with the steering axle, so that the forklift has two wheels on the left front and two wheels on the right front. However, the design is not limited to this, and in some other embodiments, the steering axle 100 can also be connected to only one wheel hub 710.

[0062] In some embodiments, the steering axle 100 further comprises two second bearings 720, and one wheel hub 710 is rotatably connected to the steering output shaft 300 through one second bearing 720. In this way, by using the second bearing 720, the rotation of the wheel hub 710 is smoother, and the frictional force acting on the wheel hub 710 during rotation is significantly reduced, thereby reducing the wear of the wheel hub 710 and prolonging the service life of the wheel hub 710.

[0063] In some embodiments, the second bearing 720 is configured as a tapered roller bearing. The tapered roller bearing can simultaneously bear radial and axial loads, and has high load-carrying capacity, and is particularly suitable for stable operation under high load and impact load. This feature enables the steering axle 100 to maintain good performance under complex working conditions. The tapered roller bearing has a certain self-alignment capability and can automatically adjust the axis deviation, so that the stress is more uniform, thereby reducing wear and fatigue and prolonging the service life of the second bearing 720. However, the design is not limited to this, and in some other embodiments, the second bearing 720 can also be configured as other types of bearings, which are not limited here.

[0064] In some embodiments, the steering output shaft 300 is provided with a mounting channel 310, and the mounting channel 310 has two first ports arranged oppositely, one wheel hub 710 covers one first port, and two second bearings 720 are arranged in the mounting channel 310. In this way, the structure of the steering axle 100 is more compact, the space occupation is reduced, and the integration of the steering axle 100 is improved. In addition, the wheel hub 710 covering the port of the mounting channel 310 can form a good seal, reducing the entry of foreign matter into the mounting channel 310, thereby prolonging the service life of the second bearing 720 and improving the reliability of the steering axle 100.

[0065] In some embodiments, the mounting channel 310 is used to accommodate lubricating oil, and the steering knuckle 100 further comprises two second seals 730, one of which is arranged between the wall of the hub 710 and the port. The second seal 730 can effectively prevent the lubricating oil from leaking from the mounting channel 310, while preventing foreign matter from entering the mounting channel 310. This helps the lubricating oil to more fully lubricate the second bearing 720, prolonging the service life of the second bearing 720.

[0066] In some embodiments, the steering knuckle 100 further comprises a bolt 740 for locking the two hubs 710 together. The connection of the bolt 740 can ensure that the connection between the two hubs 710 is more stable. In addition, the assembly and disassembly of the bolt 740 are relatively simple. When it is necessary to replace the hub 710 or perform maintenance, the bolt 740 can be quickly disassembled for corresponding operation. It is worth mentioning that the bolt 740 can be, but is not limited to, configured as a long bolt 740. In an example, the bolt 740 also passes through the mounting channel 310 and the two second bearings 720.

[0067] There are many ways to lock the two hubs 710 together by the bolt 740, and in some embodiments, the steering knuckle 100 further comprises a nut 750, and the bolt 740 is locked together with the two hubs 710 by cooperating with the nut 750. However, the design is not limited to this, and in some other embodiments, the hub 710 is provided with a threaded hole, and the bolt 740 cooperates with the threaded hole.

[0068] In some embodiments, the nut 750 is provided with two, and the two nuts 750 are arranged on the side of one hub 710 away from the other hub 710. The friction and pretightening force between the two nuts 750 work together to form a double locking mechanism, effectively preventing the nut 750 from loosening during use.

[0069] In some embodiments, the steering knuckle 100 further comprises a lock washer 760, and the bolt 740 passes through the lock washer 760, which is arranged between the two nuts 750. The lock washer 760 effectively prevents the nut 750 from loosening under vibration and impact load by increasing the friction between the nut 750 and the bolt 740. The lock washer 760 can reduce the risk of connection failure caused by loosening of the nut 750 and avoid safety hazards caused by loosening of the bolt 740.

[0070] In some embodiments, the tooth portion of the meshing rotating member 400 is configured as a helical tooth portion. The tooth surface of the helical tooth portion is inclined, and the engagement process is gradual contact and separation, so that the transmission is more stable, the impact and vibration are smaller, and the noise during operation is lower. In addition, the tooth shape design of the helical tooth portion makes the contact area larger, so that the meshing rotating member 400 can withstand greater load. However, the design is not limited to this, and in some other embodiments, the tooth portion of the meshing rotating member 400 is configured as a straight tooth portion.

[0071] According to a second aspect of the present disclosure, a vehicle is provided, which comprises the above-mentioned steering axle 100. The vehicle has all the beneficial effects of the above-mentioned steering axle 100, and the present disclosure will not be repeated here.
