Description

Technical Field

[0001] This utility model relates to the field of wheel hub technology, and in particular to a forged and stamped aluminum alloy wheel hub. Background Technology

[0002] Transfer lifts and transfer installation vehicles, based on Mecanum wheels, enable omnidirectional movement on the ground. A Mecanum wheel consists of a rim and multiple sets of rollers mounted on the outer edge of the rim, with the roller axes at an angle to the rim axis. When the drive motor rotates the Mecanum wheel, it moves forward in a direction perpendicular to the drive shaft in a normal manner. Simultaneously, the rollers on the outer edge of the rim rotate freely along their respective axes. These angled rollers generate a diagonal vector thrust on the wheel, enabling lateral movement, forward and backward movement, diagonal travel, and turning on the spot. It is very convenient to use. To ensure the rigidity of the Mecanum wheel and reduce its weight, the wheel hub is currently mostly made of aluminum alloy using a forging and stamping process.

[0003] Mecanum wheels consist of two detachably mating rim frames and multiple rolling elements positioned between the two rim frames. The rolling elements are inclined. During the assembly of Mecanum wheels, in order to ensure the assembly of the rolling elements, it is necessary to ensure that the two rim frames maintain a certain angle. However, currently, the rim frames lack positioning components, and the angle between the two rim frames needs to be manually adjusted, which is not convenient during assembly and results in low assembly efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by providing a forged and stamped aluminum alloy wheel hub.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a forged and stamped aluminum alloy wheel hub, comprising a first wheel rim frame, a second wheel rim frame, and a plurality of rolling elements disposed between the first wheel rim frame and the second wheel rim frame, characterized in that the first wheel rim frame is provided with a first connecting plate, the second wheel rim frame is provided with a second connecting plate detachably and fixedly connected to the first connecting plate, one of the first connecting plate and the second connecting plate is provided with a positioning groove, and the other is provided with a positioning protrusion that is inserted and positioned in conjunction with the positioning groove, the positioning groove and the positioning protrusion being inserted and positioned along the axial direction of the wheel hub.

[0006] Furthermore, one of the first connecting plate and the second connecting plate is also provided with a positioning post, which is located on the opposite surfaces of the first connecting plate and the second connecting plate.

[0007] Furthermore, the positioning groove and the positioning post are disposed on opposite sides of the same connecting plate, with the positioning groove located inside the positioning post.

[0008] Furthermore, the positioning groove and the positioning post are coaxially arranged.

[0009] Furthermore, both the first rim frame and the second rim frame are provided with connecting cylinders extending toward each other, and the first connecting plate and the second connecting plate are disposed at the ends of the connecting cylinders.

[0010] Furthermore, both the first and second wheel rim frames are provided with connecting holes, and the axis of the rolling element is inserted into and fitted with a mandrel. The mandrel is inserted into and fitted with the connecting hole. One end of the mandrel is provided with a limit end plate, and the other end is threadedly connected with a first nut.

[0011] Furthermore, both the first and second wheel rim frames have V-shaped mounting grooves arranged in a circumferential array at their edges. The two bottom surfaces of the V-shaped mounting grooves are provided with connecting holes, which are perpendicular to the corresponding bottom surfaces.

[0012] Compared with the prior art, the forged and stamped aluminum alloy wheel hub disclosed in this utility model has the following advantages: by setting positioning protrusions and positioning grooves that are inserted and positioned on the side of the first connecting plate and the second connecting plate that are close to each other, the positioning is used to position the first wheel rim frame and the second wheel rim frame during assembly, ensuring that the two are at a certain angle, which facilitates the subsequent installation of rolling parts and improves assembly efficiency.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] Please refer to Figure 1-7 The technical solution of this utility model is as follows: a forged and stamped aluminum alloy wheel hub, including a first wheel rim frame 10, a second wheel rim frame 11, and a plurality of rolling elements 12 disposed between the first wheel rim frame 10 and the second wheel rim frame 11, characterized in that the first wheel rim frame 10 is provided with a first connecting plate 101, the second wheel rim frame 11 is provided with a second connecting plate 110 detachably and fixedly connected to the first connecting plate 101, one of the first connecting plate 101 and the second connecting plate 110 is provided with a positioning groove 1020, and the other is provided with a positioning protrusion 112 that is inserted and positioned in conjunction with the positioning groove 1020, the positioning groove 1020 and the positioning protrusion 112 being inserted and positioned along the axial direction of the wheel hub.

[0023] Specifically, as one embodiment, the forged stamped aluminum alloy wheel hub provided in this application includes two rim frames, namely a first rim frame 10 and a second rim frame 11. A first connecting plate 101 and a second connecting plate 110 are provided on the side of the rim frames that are close to each other. Both the first connecting plate 101 and the second connecting plate 110 are perpendicular to the axis of the wheel hub. When the two rim frames are assembled, they are positioned by contact between the first connecting plate 101 and the second connecting plate 110. Then, multiple rolling elements 12 are installed between the first rim frame 10 and the second rim frame 11 to form a Mecanum wheel. This application provides positioning protrusions 112 and positioning grooves 1020 that are inserted and positioned with the positioning protrusions 112 on the side of the first connecting plate 101 and the second connecting plate 110 that are close to each other. The positioning is used to position the first rim frame 10 and the second rim frame 11 during assembly, ensuring that the two are at a certain angle, which facilitates the subsequent installation of the rolling elements 12 and improves the assembly efficiency.

[0024] In a specific implementation, the positioning protrusion 112 is a columnar structure and the positioning groove 1020 is a cylindrical groove, both of which are set parallel to the axis of the wheel hub.

[0025] Furthermore, as a specific implementation method, refer to Figure 4 , Figure 5 The first connecting plate 101 and the second connecting plate 110 are further provided with a positioning post 102, which is located on the opposite surfaces of the first connecting plate 101 and the second connecting plate 110.

[0026] It should be noted that special tooling is required when assembling the wheel hub. To facilitate assembly, a positioning post 102 is provided on one of the first connecting plate 101 and the second connecting plate 110. A groove adapted to the positioning post 102 is provided on the support plate of the tooling. The positioning post 102 and the groove on the tooling can be used for positioning, which prevents the wheel rim frame from rotating relative to the tooling during assembly. This facilitates assembly and also prevents scratches on the wheel rim frame caused by relative friction between the wheel rim frame and the tooling.

[0027] Furthermore, as a preferred embodiment, refer to Figure 5 , Figure 6 The positioning groove 1020 and the positioning post 102 are disposed on two opposite sides of the same connecting plate, with part of the positioning groove 1020 located inside the positioning post 102.

[0028] In one specific implementation, both the positioning post 102 and the positioning groove 1020 are disposed on opposite sides of the first connecting plate 101, with the bottom end of the positioning groove 1020 extending into the positioning post 102. This arrangement allows for a sufficiently deep positioning groove 1020 when the thickness of the first connecting plate 101 is relatively small, ensuring effective insertion and positioning between the positioning groove 1020 and the positioning protrusion 112. It is understood that the positioning groove 1020 and the positioning post 102 can also be disposed on the second connecting plate 110 simultaneously, achieving the same effect.

[0029] Furthermore, as a preferred embodiment, the positioning groove 1020 and the positioning post 102 are coaxially arranged. Preferably, by coaxially arranging the positioning groove 1020 and the positioning post 102, the connecting plate can be pressed by a forging die during processing to integrally form the positioning groove 1020 and the positioning post 102, thereby facilitating processing and manufacturing.

[0030] Specifically, it should be noted that in actual use, the transport vehicle is equipped with an axle 2, which is the half-shaft of the vehicle's wheels, drive shaft, etc. A connecting plate 20 is set at the end of the axle 2. Six connecting screws 21 are evenly spaced around the axle 2 on the connecting plate 20. Six through holes 103 are correspondingly set on the first connecting plate 101 and the second connecting plate 110. When the positioning protrusion 112 is inserted into the positioning groove 1020, the through holes 103 on the first connecting plate 101 and the second connecting plate 110 correspond one-to-one. The through holes 103 are inserted into the corresponding connecting screws 21, and then the second nut 22 is threadedly connected to the end of the connecting screw 21 to lock it.

[0031] Furthermore, as a specific implementation method, refer to Figures 1-5 Both the first rim frame 10 and the second rim frame 11 have connecting cylinders extending towards each other, and the first connecting plate 101 and the second connecting plate 110 are disposed at the ends of the connecting cylinders. Specifically, the connecting cylinder, the rim frame, and the connecting plate are all integrally formed.

[0032] Furthermore, as a specific implementation method, refer to Figures 1-3 , Figure 7 Both the first wheel rim frame 10 and the second wheel rim frame 11 are provided with connecting holes 100. The axis of the rolling element 12 is inserted and fitted with a mandrel 121. The mandrel 121 is inserted and fitted with the connecting hole 100. One end of the mandrel 121 is provided with a limit end plate 120, and the other end is threadedly connected with a first nut 122. Specifically, both ends of the rolling element 12 are provided with bearings 123. The mandrel 121 is inserted into the bearing 123, so that the mandrel 121 and the rolling element 12 are in rotational engagement. During assembly, the rolling element 12 is first assembled with the bearing 123. Then, the rolling element 12 is placed in the installation position between the first wheel rim frame 10 and the second wheel rim frame 11. Then, the mandrel 121 is passed through the connecting holes 100 on the first wheel rim frame 10 and the second wheel rim frame 11 in sequence, and locked to the end of the mandrel 121 by the first nut 122. Then, the rolling element 12 is installed in sequence.

[0033] Furthermore, as a preferred embodiment, refer to Figure 3 A positioning part 111 corresponding to the connecting hole 100 is fixedly provided on the second rim frame 11. The limiting end plate 120 is hexagonal plate-shaped, and the positioning part 111 forms a hexagonal positioning groove 1020 that is circumferentially limited to the limiting end plate 120. With this setting, the mandrel 121 can be circumferentially limited by the positioning part 111, which facilitates the subsequent installation of the first nut 122.

[0034] Furthermore, as a preferred embodiment, refer to Figure 4 , Figure 5The first wheel rim frame 10 and the second wheel rim frame 11 both have V-shaped mounting grooves 1000 arranged in a circumferential array on their edges. Each of the two bottom surfaces of the V-shaped mounting groove 1000 has a connecting hole 100, which is perpendicular to the corresponding bottom surface. Specifically, this arrangement allows the rolling element 12 to be installed with either of the two connecting holes 100, enabling the rolling element 12 to be installed at two angles. This allows for angle adjustment as needed, improving adaptability.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
