[0013] Beneficial Effects

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, by providing a movable positioning plate, a threaded rod, a threaded sleeve and a rotating head, the process of installing and fixing the brake hub bearing is more convenient. The device can adjust the position and distance of the movable positioning plate in the middle of the fixing ring, so that the movable positioning plate can fix bearings of different sizes. The device has better adaptability and is more convenient to use. The bearing unit of the brake hub is placed in the middle of the fixing ring, and then the rotating heads of the four groups of the outer walls of the fixing ring are rotated respectively to drive the threaded sleeve to rotate on the inner wall of the fixing ring. When the threaded sleeve rotates, the threaded rod will move up and down in the middle of the threaded sleeve, pushing the movable positioning plate to move, so that the four groups of movable positioning plates can clamp and fix the outer wall of the bearing unit of the brake hub. The operation is simple and convenient. When disassembly is required, the rotating head can be rotated in the opposite direction, and the disassembly operation is also convenient.

[0016] 2. In the present invention, by setting up four groups of fixing rings and No. 2 fixing bolts, the installation and disassembly process of the device is more convenient and simple, the fixing effect of the brake hub bearing unit is better, the assembly and disassembly process of the bracket is more convenient and simple, and the installation and use process of the device is more convenient. The ends of the four groups of fixing rings are aligned in pairs, and then the No. 2 fixing bolts are passed between the ends of every two groups of fixing rings. The four groups of fixing rings are connected in the first place and fixed to form a ring, so that the bearing unit of the brake hub can be fixed, and the operation is simple and convenient.

[0017] 3. In the present invention, by providing No. 1 fixing bolts, mounting grooves and soft rubber washers, the device fixes the mounting base and the fixed base plate more tightly together, so that the fixed base plate can better fix the mounting base, and the mounting base can also be better installed on the brake wheel hub, so that the installation and fixing effects are better. The provided soft rubber washers can allow the bracket to have a certain buffering and shock-absorbing effect when in use, and can also eliminate the gap in the connection between the mounting base and the fixed base plate, making the connection tighter and preventing loosening. The soft rubber washers are placed between the mounting grooves between the mounting base and the fixed base plate, and then the No. 1 fixing bolts are passed through the through holes in the middle of the mounting base, the fixed base plate and the soft rubber washers to fix the mounting base, the fixed base plate and the soft rubber washers. The mounting base and the fixed base plate will have a squeezing effect on the soft rubber washers, and the soft rubber washers will make the connection and fixing effect of the mounting base and the fixed base plate better, and also provide a certain shock-absorbing effect for the mounting base.

[0018] 4. In the present invention, by providing a bearing seat, a fixing plate, reinforcing ribs and an inner mounting ring, the device can make the internal structure more stable while reducing the overall weight of the bracket, making the structure of the bracket more stable while reducing its own weight. The inner mounting ring is fixed in the middle of the bearing seat by the reinforcing ribs and the fixing plate, and a larger gap is formed between the bearing seat and the inner mounting ring, thereby greatly reducing the weight of the bracket.

[0019] 5. In the present invention, by providing the oil inlet pipe and the oil outlet, people can conveniently oil the brake hub bearing unit in the middle of the bracket and lubricate the hub bearing unit. The oiling operation is also very simple and convenient. There is no need to disassemble the bracket. The sealing cover is rotated and removed from the upper end of the oil inlet pipe, and then a funnel or other tool is used to add lubricating oil to the middle of the oil inlet pipe. The lubricating oil can flow inside the oil inlet pipe and then be discharged from the oil outlet and fall into the bearing unit, thus completing the oiling operation. By providing the heat dissipation holes, the bracket also has a very good heat dissipation effect on the bearing unit. The air will flow between the bearing seat and the inner mounting ring through the heat dissipation holes to discharge the heat generated during the rotation of the bearing unit, dissipate the heat of the bearing unit, and achieve a better heat dissipation effect.

[0020] 6. In the present invention, through the provision of the support arm, the buffer rod No. 1 fixed block and the No. 2 fixed block, the device can provide stable support and buffering effect to the bracket, so that the bracket can better install the brake hub bearing unit, the support of the bracket is also better, and it also has good buffering and shock absorbing effects. The device is installed and connected to the chassis or frame of the car through the support arm. When the bracket encounters vibration, the support arm will undergo some deformation at the upper end of the connecting rod, so that the buffer rod will perform corresponding telescopic activities to absorb the energy generated by the vibration of the support arm. The two ends of the buffer rod will respectively rotate on the side wall of the No. 2 fixed block and the upper end of the support arm through the provision of the No. 1 rotating head and the No. 2 rotating head to adapt to the deformation of the support arm, so that the bracket can provide a buffering and shock absorbing effect for the bearing unit of the brake hub.

[0035] like Figure 2 as well as Figure 3 As shown, a soft rubber gasket 15 is arranged between the mounting base 1 and the fixed base plate 3, and a plurality of mounting holes are also arranged in the middle of the soft rubber gasket 15. The soft rubber gasket 15 makes the mounting base 1 and the fixed base plate 3 connected more tightly. The No. 1 fixing bolt 8 passes through the mounting base 1, the soft rubber gasket 15 and the mounting hole in the middle of the fixed base plate 3 to connect the mounting base 1 and the fixed base plate 3. The mounting base 1 and the fixed base plate 3 will squeeze the soft rubber gasket 15, and the soft rubber gasket 15 will deform, making the mounting base 1 and the fixed base plate 3 connected more tightly.
