Therefore, the above terms cannot be understood as limiting this application.

[0051] The present application will be described in further detail below with reference to the accompanying drawings. Figures 1 to 8 illustrate.

[0052] This embodiment provides a mining truck axle tilting mechanism, which is used in the field of engineering machinery technology. Specifically, Figures 1 to 8As shown, it includes an axle 1, a frame 2, a swing frame 3 and a swing shaft 4. The upper end of the axle 1 is connected to the frame 2, and the lower end is connected to the swing frame 3. The swing frame 3 is used to support the axle 1 and bear the load of the axle 1, and can absorb and reduce the impact force and vibration of the axle 1. The axle 1 is used to support the wheels and bear the load of the wheels. During the driving of the vehicle, the axle 1 can adapt to the ups and downs of different road surfaces, ensure contact with the ground, and improve the stability of the vehicle. One end of the swing shaft 4 is connected to the frame 2, and the other end of the swing shaft 4 is connected to the axle 1. When the mining truck is driving, the axle 1 can swing up and down around the swing shaft 4. When the mining truck is driving on a rugged road, the swing shaft 4 can limit the swing angle of the axle 1 and the swing frame 3, which helps to control the tilt and rotation functions of the axle 1 and ensure the stability and balance of the frame 2. In this embodiment, a hinge point connected to the swing frame 3 is provided on the axle 1, and the hinge point is located in the middle of the axle 1. The center of gravity of the axle 1 is located in the middle of the axle 1, so that the axle 1 can swing around its own center, reducing the swing angle of the axle 1, reducing the risk of rollover or tilting, and enhancing the flexibility of the axle 1, so that the axle 1 can better adapt to the ups and downs under different road conditions, improve the stability and balance of the mining truck during driving, and thus extend the service life of the axle 1.

[0053] Specifically, such as Figure 2 As shown, the swing frame 3 is provided with a buffer 31, and the vehicle frame 2 is provided with a limiter 21 that cooperates with the buffer 31. The buffer 31 is a cushion with a rebound effect. The buffer 31 cooperates with the limiter 21 to limit the swing angle of the axle 1 during its swing. The axle 1 can swing up and down relative to the swing axis 4. When the axle 1 encounters uneven ground, the axle 1 will deflect toward the vehicle frame 2. At this time, the angle between the axle 1 and the vehicle frame 2 does not exceed 8°, that is, the swing angle of the axle 1 toward the vehicle frame 2 does not exceed 8°, to ensure the stability of the vehicle frame 2. When the mining truck is driving, if the swing angle of the axle 1 reaches the maximum value within a specified range, the buffer 31 will contact the limiter 21, causing the buffer 31 to rebound, restoring the axle 1 to the specified swing angle range, ensuring the stability and balance of the truck. At the same time, the buffer 31 acts as a buffer, absorbing the impact force of the axle 1 during its swing, effectively reducing the impact force of the axle 1 during its swing, and improving the safety and stability of the truck during driving.

[0054] like Figure 3As shown, the limit member 21 includes a first connection portion 211 and a second connection portion 212, one side of the first connection portion 211 is fixedly connected to the frame 2, and the other side of the first connection portion 211 is fixedly connected to the second connection portion 212, the side wall of the first connection portion 211 is inclined toward the frame 2, and the connection angle between the first connection portion 211 and the second connection portion 212 is an acute angle, which can be 30°, 45°, or 60°. The second connection portion 212 protrudes toward the buffer member 31, and the thickness of the first connection portion 211 is greater than or equal to the thickness of the second connection portion 212, which is beneficial to provide a certain supporting force for the second connection portion 212, wherein, when the axle 1 moves toward the frame 2, the buffer member 31 abuts against the second connection portion 212, and the diameter of the outer surface of the buffer member 31 is less than or equal to the diameter of the second connection portion 212, which can ensure that the buffer member 31 can accurately abut against the second connection portion 212, reducing the gap, simplifying the installation and improving the stability.

The connection between the first connecting plate 51 and the second connecting plate 52 is provided with a chamfer, and the connection between the second connecting plate 52 and the third connecting plate 53 is also provided with a chamfer. The end of the first connecting plate 51 away from the second connecting plate 52 is also provided with a chamfer. By setting the chamfer, the chamfer can reduce sharp edges or corners, reduce the impact force and friction received by the mounting plate 5 during use, reduce stress concentration, and extend the service life of the mounting plate 5. Among them, two threaded holes 54 are provided on each of the first connecting plates 51, and four threaded holes 54 are provided on the third connecting plate 53. The threaded holes 54 are elliptical structures, and the threaded holes 54 are adapted to the shape of the fixing parts 6. The threaded holes 54 are arranged at intervals, and the fixing parts 6 are connected to the positioning pressure plate 32 through the threaded holes 54.

[0057] like Figure 6 As shown, the positioning pressure plate 32 includes a bottom plate 321 and two side plates 322 arranged in parallel. The two side plates 322 are respectively connected to the opposite sides of the bottom plate 321. The side plates 322 protrude toward the mounting plate 5. The upper surface of the side plate 322 away from the bottom plate 321 is inclined toward the swing frame 3, and the lower surface of the side plate 322 away from the bottom plate 321 is inclined toward the mounting plate 5. The bottom plate 321 is corresponding to the first connecting plate 51, and the side plate 322 is corresponding to the third connecting plate 53. The axle 1 has at least Part of it is located on the bottom plate 321, and the two side plates 322 limit the axle 1, which can prevent the axle 1 from sliding out of the bottom plate 321, thereby limiting the position of the axle 1 and strengthening the connection between the axle 1 and the swing frame 3.
