Description

Technical Field

[0001] The utility model relates to the field of automobile parts, in particular to an automobile wheel hub structure. Background Technique

[0002] A complete automobile wheel hub includes a rim, a wheel disc and spokes. The automobile wheel hub is mounted on the axle of the automobile through the wheel disc.

[0003] After many car owners buy a new car, they will install a flange between the wheel disc and the axle of the car to widen the track, thereby improving the stability of the car when cornering quickly and reducing the roll of the car.

[0004] However, traditional flange plates are fixed to the axle through fixing components. Therefore, there is actually a lack of connection structure between the wheel hubs. The addition of the flange plate will increase the distance between the wheel hub and the axle. Due to the lever principle, this will make the bolts used to connect the wheel hub on the axle receive greater shear force when the vehicle turns, and it is easy for the bolts to break and cause the wheel to fall off the axle. Content of the Utility Model

[0005] This application provides an automobile wheel hub structure. By adding a connection structure between the flange plate and the wheel hub, the shear force received by the bolts during vehicle turning is dispersed, thereby improving the stability when the wheel hub is mounted on the axle.

[0006] The following technical solutions are adopted for the automobile wheel hub structure provided by this application:

[0007] An automobile wheel hub structure includes a rim, a wheel disc, and a plurality of spokes. A plurality of first assembly holes are formed in the wheel disc. A flange plate is connected to the inner side surface of the wheel disc. A plurality of plug bolts are provided on the flange plate. The plurality of plug bolts are distributed annularly. A plurality of jack holes are formed in the wheel disc, and the plurality of plug bolts are respectively inserted into the plurality of jack holes.

[0008] By adopting the above technical solution, when the vehicle turns, the plug bolts will help disperse the shear force received by the bolts, reduce the risk of bolt breakage, and thus improve the stability when the wheel hub is mounted on the axle.

[0009] Preferably, a plurality of reinforcing ribs are provided at the joints between the wheel disc and the plurality of spokes, and an avoidance space for the nut to pass through is formed between the plurality of reinforcing ribs.

[0010] By adopting the above technical solution, the connection strength between the wheel disc and the plurality of spokes is enhanced, and the overall strength of the wheel hub is improved.

[0011] Preferably, two adjacent spokes are respectively connected to the end and the tail of the same reinforcing rib.

[0012] By adopting the above technical solution, during the driving process of the vehicle, the pressure can be better dispersed between adjacent spokes through the reinforcing ribs, so that the pressure-bearing limit of each spoke is increased, thereby realizing the improvement of the hub strength.

[0013] Preferably, a plurality of mounting holes are formed in the flange, and the plurality of bolts are respectively slidably connected in the plurality of mounting holes. A first spring is provided in each of the plurality of mounting holes. One ends of the plurality of first springs respectively abut against the plurality of bolts, and the other ends of the plurality of first springs respectively abut against the bottom walls of the plurality of mounting holes.

[0014] By adopting the above technical solution, when the hub is installed on the axle, first install the flange on the axle. Then the worker holds the hub and aligns the plurality of jack holes with the plurality of bolts and the plurality of first assembly holes with the plurality of bolts on the axle. Then push the hub so that the plurality of bolts are inserted into the plurality of jack holes. As the hub moves, the wheel disc will press the plurality of bolts into the plurality of mounting holes and cause the plurality of first springs to be compressed. Finally, the wheel disc will abut against the flange. Subsequently, when the tire needs to be disassembled from the axle, after removing the nuts on the wheel disc, without the bolts and nuts limiting the wheel disc, the plurality of first springs will rebound and push the plurality of bolts to push the wheel disc away from the flange, making it easier to remove the hub from the axle.

[0015] Preferably, positioning grooves are formed on the side walls of the plurality of jack holes along the direction perpendicular to the axis of the wheel disc, and positioning blocks are provided on the plurality of bolts. The plurality of positioning blocks are respectively inserted and matched with the plurality of positioning grooves.

[0016] By adopting the above technical solution, the cooperation between the positioning block and the positioning groove can improve the connection strength and connection stability between the flange and the wheel disc.

[0017] Preferably, the lengths of the plurality of positioning blocks are greater than the lengths of the plurality of positioning grooves. When the plurality of positioning blocks are inserted into the plurality of positioning grooves, the ends of the plurality of positioning blocks away from the corresponding bolts all extend out of the positioning grooves.

[0018] By adopting the above technical solution, as long as the plurality of positioning blocks are inserted into the plurality of positioning grooves, the plurality of bolts will be inserted into the plurality of jack holes. Therefore, by increasing the length of the positioning blocks, workers can better observe the cooperation between the plurality of positioning blocks and the positioning grooves through the plurality of spokes when the hub is installed on the axle, which is convenient for the assembly of the flange and the wheel disc.

[0019] Preferably, the diameters of the ends of the plurality of positioning blocks away from the flange gradually increase from the end away from the flange to the end close to the flange, and the end faces of the ends of the plurality of positioning blocks away from the flange are arc-shaped end faces.

[0020] By adopting the above technical solution, the positioning block can be inserted into the corresponding positioning groove more easily, reducing the assembly difficulty between the flange and the wheel disc.

[0021] The technical effects of the present utility model are mainly reflected in the following aspects:

[0022] 1. In the present utility model, through the cooperation of the plug bolt and the jack, when the vehicle turns, the plug bolt helps to disperse the shear force it receives, thereby improving the stability when the wheel hub is installed on the axle;

[0032] The following further details the present application with reference to the drawings, so that the technical solution of the present application is easier to understand and master.

[0033] Refer to Figure 1, a wheel hub structure of this embodiment includes a rim 1, a wheel disc 2, and multiple spokes 3. Multiple first assembly holes 21 are provided on the wheel disc 2. When the wheel hub is installed on the axle, multiple bolts on the axle will pass through the multiple first assembly holes 21, and then nuts are used to fix the wheel hub on the axle. Multiple reinforcing ribs 23 are provided at the joints between the wheel disc 2 and the multiple spokes 3, and avoidance spaces for the nuts to pass through are formed between the multiple reinforcing ribs 23. Adjacent two spokes 3 are respectively connected to the end and the tail of the same reinforcing rib 23.

[0034] Refer to Figures 2 - 6 , a flange 4 is connected to the inner side surface of the wheel disc 2. Multiple mounting holes 42 are annularly distributed on the flange 4. A bolt 41 is slidably connected in each mounting hole 42 along the axial direction of the flange 4. Multiple first springs 43 are placed in the multiple mounting holes 42. One ends of the multiple first springs 43 respectively abut against the multiple bolts 41, and the other ends of the multiple first springs 43 respectively abut against the bottom walls of the multiple mounting holes 42.

[0035] Refer to Figures 2 - 5 , multiple jack holes 22 are provided on the wheel disc 2, and the multiple bolts 41 are respectively inserted into the multiple jack holes 22. Positioning grooves 24 are provided on the side walls of the multiple jack holes 22 along the direction perpendicular to the axis of the wheel disc 2. Positioning blocks 44 are fixed on the multiple bolts 41, and the multiple positioning blocks 44 are respectively inserted and matched with the multiple positioning grooves 24.

[0036] Refer to Figure 3 and Figure 6 , the lengths of the multiple positioning blocks 44 are greater than the lengths of the multiple positioning grooves 24. When the multiple positioning blocks are inserted into the multiple positioning grooves 24, the ends of the multiple positioning blocks 44 far from the corresponding bolts 41 all extend out of the positioning grooves 24. The diameters of the ends of the multiple positioning blocks 44 far from the flange 4 gradually increase from the end far from the flange 4 to the end close to the flange 4, and the end faces of the ends of the multiple positioning blocks 44 far from the flange 4 are arc end faces 45.

[0037] Refer to Figures 3 - 6 , when the wheel hub is installed on the axle, first the flange 4 is installed on the axle, and then the wheel hub is held first and the multiple jack holes 22 are aligned with the multiple bolts 41, and the multiple first assembly holes 21 are aligned with the multiple bolts on the axle. Then the wheel hub is pushed so that the multiple bolts 41 are inserted into the multiple jack holes 22. As the wheel hub moves, the wheel disc 2 will press the multiple bolts 41 into the multiple mounting holes 42 and cause the multiple first springs 43 to be compressed. Finally, the wheel disc 2 will abut against the flange 4. Subsequently, when the tire needs to be disassembled from the axle, after removing the nuts on the wheel disc 2, without the limit of the bolts and nuts on the wheel disc 2, the multiple first springs 43 will rebound to push the multiple bolts 41 to push the wheel disc 2 away from the flange 4, making it easier to remove the wheel hub from the axle.

[0038] Of course, the above are only typical examples of this application. In addition, this application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by this application.
