[0003] At present, the traditional four-way shuttle car includes multiple wheels, which enhances the stability and load capacity of the wheels to a certain extent. However, the complexity of the wheel control system follows. The commonly used technology is to design a linked control system for multiple wheels, or to design an independent control system for each wheel. Obviously, the linked control system is relatively simple in control, but once the control system fails, the entire four-way shuttle car will not be able to operate normally. While the independent control system is more complex in control, it needs to ensure the coordinated operation between multiple wheels.
[0004] Therefore, it is of great significance to design a four-way shuttle car wheel group that can ensure the safe operation of the four-way shuttle car without increasing the complexity of the control system. The design of this new wheel group not only improves the stability and reliability of the four-way shuttle car, but also reduces maintenance costs and improves production efficiency to a certain extent.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0024] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0025] Please refer to Figure 1 In the present embodiment, a four-way shuttle vehicle wheel set mainly comprises:
[0026] The X-direction wheel set is responsible for pushing the four-way shuttle vehicle to move along the X-axis direction. These X-direction wheel sets can effectively drive the four-way shuttle vehicle to move smoothly along the X-axis direction under the precise control of the control system. Similarly, the Y-direction wheel set is responsible for pushing the four-way shuttle vehicle to move along the Y-axis direction. These Y-direction wheel sets can also effectively drive the four-way shuttle vehicle to move smoothly along the Y-axis direction under the precise control of the control system.
[0027] The X-axis direction and the Y-axis direction refer to two mutually perpendicular directions in the plane (usually horizontal plane) in which the four-way shuttle vehicle runs. The main function of the control system is to control the four-way shuttle vehicle to perform various corresponding actions, such as forward movement, backward movement, left movement, right movement, and jacking, etc. Since the control system belongs to the prior art category, its details will not be described in more detail in this application.
[0028] In the embodiment, the X-direction wheel group mainly includes an X-direction driving wheel group and a driven wheel group. The X-direction driving wheel group can drive the four-way shuttle vehicle to move along the X-axis direction under the drive of the X-direction power shaft. The X-direction driven wheel group is not directly connected with the X-direction power shaft, so it has no power source and can only move under the drive of the X-direction driving wheel group.
[0029] Similarly, the Y-direction wheel group also includes a Y-direction driving wheel group and a driven wheel group. The Y-direction driving wheel group can drive the four-way shuttle vehicle to move along the Y-axis direction under the drive of the Y-direction power shaft. The Y-direction driven wheel group is not directly connected with the Y-direction power shaft, so it has no power source and can only move under the drive of the Y-direction driving wheel group.
[0030] In order to ensure the normal operation of the four-way shuttle vehicle, the driving wheel groups in the X-direction and the Y-direction in the embodiment each include a plurality of driving wheels. Each driving wheel is tightly connected with the driving shaft of the four-way shuttle vehicle through a tight sleeve. The driven wheel groups in the X-direction and the Y-direction include a plurality of driven wheels. Each driven wheel is tightly connected with the frame of the four-way shuttle vehicle through a bearing and a rolling vehicle axle.
[0031] Please refer to Figure 2 and Figure 3 It can be found that the driving wheel includes coaxially arranged driving rotors 12, a fixed axle 13 and a tight sleeve 11. These driving rotors are connected together with the driving shaft of the four-way shuttle vehicle through the fixed axle and the tight sleeve.
[0032] Please refer to Figure 4 and Figure 5 The driven wheel includes coaxially arranged a first clasp 22, a first bearing 23, a driven rotor 24, a second bearing 25, a second clasp 26 and an axle end baffle 27. The installation positions and relationships of the components are shown in Figure 5 The one end of the driven rotor 24 is connected with the rolling vehicle axle 21. These components collectively ensure that the driven wheel can be smoothly connected with the frame of the four-way shuttle vehicle.
[0033] Please refer to Figure 1 In the embodiment, the driving wheel group moving along the X-axis direction includes a first driving wheel group 101 and a second driving wheel group 102 symmetrically arranged on both sides of the vehicle body in the X-axis direction. Both of the driving wheel groups include two independent driving wheels, thereby ensuring the stable movement of the four-way shuttle vehicle in the X-axis direction. When one of the driving wheels fails, the other driving wheel can still provide power for the four-way shuttle vehicle in the X-axis direction.
[0034] The driven wheel group moving along the Y-axis direction includes the third driven wheel group 203 and the fourth driven wheel group 204 which are symmetrically arranged on both sides of the vehicle body along the Y-axis direction. Both of the driven wheel groups also include two driven wheels, thereby ensuring the stable movement of the four-way shuttle vehicle along the Y-axis direction.
[0035] The driven wheel group moving along the Y-axis direction includes the third driven wheel group 203 and the fourth driven wheel group 204 which are symmetrically arranged on both sides of the vehicle body along the Y-axis direction. Both of the driven wheel groups also include two driven wheels, thereby ensuring the stable movement of the four-way shuttle vehicle along the Y-axis direction.
[0036] The driven wheel group moving along the Y-axis direction includes the third driven wheel group 203 and the fourth driven wheel group 204 which are symmetrically arranged on both sides of the vehicle body along the Y-axis direction. Both of the driven wheel groups also include two driven wheels, thereby ensuring the stable movement of the four-way shuttle vehicle along the Y-axis direction.
[0037] The above only describes the preferred embodiments of the present application, and is not intended to limit the protection scope of the present application.
