Description

Technical Field

[0001] The utility model relates to the technical field of wheel hubs, in particular to an aluminum alloy wheel hub for vehicles. Background Art

[0002] The wheel hub is a carrier-shaped accessory on a car tire, which is mainly used to carry the rubber tire. The wheel hub is fixed to the rotating shaft, and the rotating shaft can drive the wheel hub to rotate when it rotates.

[0003] The tire on the wheel hub is a consumable and needs to be replaced after being used for a period of time or when it is damaged. During the replacement process, the wheel hub needs to be disassembled, and then the tire and the wheel hub need to be separated by equipment. However, during the removal of the wheel hub, the bolts on the wheel hub need to be rotated off one by one. In the repair shop, you can use a pistol to quickly disassemble it, but if the vehicle is damaged on the highway or in sparsely populated areas, you can only use a wrench for disassembly. The efficiency of disassembly using a wrench is very low, and there are also safety hazards when operating on the highway or in sparsely populated areas for a long time. Utility Model Content

[0021] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0022] A vehicle aluminum alloy wheel hub provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0023] Combination Figure 1-3 As shown, the utility model provides an aluminum alloy wheel hub for a vehicle, including a hub frame 1, the inner wall of the hub frame 1 is annularly fixedly connected to a support rod 2, one side of the support rod 2 is fixedly connected to a fixing ring 4, the fixing ring 4 is rotatably connected to an active gear ring 9, the side of the active gear ring 9 is meshingly connected to a driven gear ring 10, the center position of the driven gear ring 10 is threadedly connected to a fixing bolt 11 in a through-shaped manner, one end of the fixing bolt 11 is slidably connected to one side of the fixing ring 4 in a through-shaped manner; the side wall of the support rod 2 is fixedly connected to a reinforcing rib 3, the reinforcing rib 3 is fixedly connected between the support rods 2, the inner wall of the fixing ring 4 is symmetrically fixedly connected to a magnet rod 7, the number of the magnet rod 7 is two, and the magnet rod 7 can keep the gear teeth inside the fixing ring 4 relatively stable, use the adsorption force of the magnetic field to form a fixing force, slow down the shaking of parts, and at the same time adsorb the cover plate 5 to play an auxiliary fixing effect.

[0024] In the first embodiment, when the torsion bar 8 rotates, the active gear ring 9 can be driven to rotate by the driven gear ring 10 next to it. When the driven gear ring 10 rotates, the fixing bolt 11 can be driven to move. During the rotation process, the fixing bolt 11 can be moved by utilizing the cooperation of the external thread and the internal thread, and then the wheel hub is fixed on the rotating shaft. This can improve the installation efficiency of the wheel hub, avoid the operator staying next to the car, and avoid the occurrence of secondary traffic accidents.

[0025] One side of the active gear ring 9 is fixedly connected with a torsion bar 8, one side of the torsion bar 8 is slidably connected with a limit block 15, the limit block 15 is L-shaped, one side of the limit block 15 is fixedly connected with an extrusion block 14, one side of the extrusion block 14 is slidably connected with a push block 13, one side of the push block 13 is fixedly connected with a lock body 12, one end of the lock body 12 is rotatably connected with a cover plate 5, one side of the cover plate 5 is fixedly connected with an anti-theft lock 6, one side of the anti-theft lock 6 is provided with a keyhole 17, the extrusion block 14 is symmetrically slidably connected to one side of the cover plate 5, there are two extrusion blocks 14, one side of the extrusion block 14 is fixedly connected with a spring 16, one end of the spring 16 is fixedly connected to the inner wall of the cover plate 5, and there are two springs 16.

[0026] In the second embodiment, after the wheel hub is installed, the cover plate 5 is covered on one side of the fixing ring 4, and then the limit block 15 is passed through the torsion bar 8, and then the lock body 12 is driven to rotate. When the lock body 12 rotates, the push block 13 can be driven to rotate, and the push block 13 can leave the extrusion block 14 when moving. Then the spring 16 drives the extrusion block 14 to reset, thereby driving the two limit blocks 15 to move closer, so that the limit blocks 15 can form two limits, one limit is to limit the cover plate 5 from being pulled open, and the other limit is to limit the rotation of the torsion bar 8, thereby ensuring the firmness of the fixation of the wheel hub and the rotating shaft.

[0027] The working principle and use process of the utility model are as follows: first, the wheel hub is installed on the fixed disk of the rotating shaft, and then the fixing bolt 11 on the driven gear ring 10 is aligned with the fixing hole. After fixing, the active gear ring 9 is rotated. When the active gear ring 9 rotates, it drives the driven gear ring 10 to rotate. The driven gear ring 10 drives the external thread of the fixing bolt 11 to cooperate with the internal thread of the driven gear ring 10 so that the fixing bolt 11 moves, and then the fixing is formed. After the wheel hub is fixed, the cover plate 5 is covered to allow the limit block 15 to pass through the torsion bar 8, and then the car key is inserted into the keyhole 17, and then the lock body 12 is driven to rotate. When the lock body 12 rotates, it can drive the push block 13 to leave the extrusion block 14, and then the extrusion block 14 can move under the action of the spring 16. When the extrusion block 14 moves, it can drive the limit block 15 to approach.
