Description

Technical fields:

[0001] This utility model belongs to the field of wheel hub technology, and specifically refers to a wheel hub with detachable ribs. Background technology:

[0002] A wheel hub is a cylindrical metal component that supports the tire from within and is mounted on a central axle.

[0003] For example, Chinese utility model patent CN208376417U discloses an automobile wheel hub whose strength can be improved by using detachable spokes. It includes a wheel hub body, a mounting part, and multiple spokes. Each spoke has a vent hole. A first mounting hole is provided on the left side of the vent hole of each spoke, and a second mounting hole is provided on the right side of the vent hole of each spoke. A third mounting hole is provided on the wheel hub body between two spokes. Two adjacent spokes and their corresponding wheel hub bodies form a triangular through groove. A first positioning spoke is provided between the second mounting hole and the third mounting hole on the right side of the through groove. A second positioning spoke is provided between the first mounting hole and the first positioning spoke on the left side of the through groove. One side of the first positioning spoke has a mounting through hole that communicates with the third mounting hole, and the other side has a first limiting post that extends into the second mounting through hole. The second positioning spoke has second limiting posts on both sides that can extend into the mounting through hole or the first mounting hole.

[0004] The aforementioned car wheel hubs increase their strength by installing long spokes, but during driving, when torque changes abruptly, stress can easily form instantaneous high stress at the weak points of the spokes, making the spokes prone to damage, which needs to be improved. Summary of the Invention:

[0005] The purpose of this invention is to provide a wheel hub with detachable ribs to solve the technical problems mentioned in the background section.

[0006] This utility model is implemented as follows:

[0007] A wheel hub with detachable ribs includes a hub body and spokes. The spokes include a mounting portion and a plurality of spokes connected between the mounting portion and the hub body. A plurality of ribs are threadedly connected between the mounting portion and the hub body by a screw. The plurality of ribs and the plurality of spokes are distributed at equal intervals around the mounting portion in a circumferential direction, and the ribs are located between adjacent spokes. The ribs are annular, and their two sides abut against the sidewalls of two adjacent spokes, respectively.

[0008] By adopting the above technical solution, the ribs are added to the wheel hub using screws, increasing the structural strength of the hub. The annular ribs abut against the spokes on both sides, and the annular shape of the ribs, compared to adding long spokes, helps to form a more stable load-bearing support structure, enhancing the structural stiffness of the wheel hub under torque. It also helps to quickly disperse stress, reduce stress concentration, and thus makes the ribs less prone to damage.

[0009] Preferably, an elastic washer is fitted on the screw, the screw passes through the rib and is threadedly connected to the mounting part or the wheel hub body, and the elastic washer is pressed against the rib and the mounting part or the wheel hub body.

[0010] By adopting the above technical solution, the rib is pressed against the mounting part or the wheel hub body by the elastic gasket, which helps to reduce the gap at the connection between the reinforcing rib and the mounting part and the wheel hub body, and reduces the entry of rainwater, sand and dust into the gap.

[0011] Preferably, the screw includes a shaft and a screw head. The rib has an installation opening for the shaft to pass through. A warning bladder is embedded in the rib and is arranged circumferentially around the installation opening. A spike is machined on the screw head to pierce the warning bladder. A sealing block is provided on the screw head to seal the warning bladder after it is pierced by the spike. The sealing block is arranged circumferentially around the spike. The warning bladder contains a warning liquid.

[0012] By adopting the above technical solution, when the screw is tightened, the screw head presses against the reinforcing rib, causing the spike to pierce into the warning sac. The sealing block presses against the gap between the spike and the warning sac to seal. When the bolt loosens, the screw head moves away from the reinforcing rib, the sealing block and the spike disengage from the warning sac, and the warning liquid in the warning sac flows out through the hole pierced by the spike and stains the surface of the rib, which is beneficial for timely detection when the bolt becomes loose.

[0013] Preferably, the indicator solution contains a fluorescent agent.

[0014] By adopting the above technical solutions, the prompts are made clearer.

[0015] Preferably, the rib has a groove, and the screw head is inserted into the groove.

[0016] By adopting the above technical solution, the settling tank provides a compression space for the sealing block, making it less likely for the indicator liquid to leak out after the indicator sac is punctured.

[0017] Preferably, the rib has three mounting openings arranged in a triangular pattern, with two mounting openings corresponding to the inner ring edge of the wheel hub body and the other mounting opening corresponding to the mounting part.

[0018] By adopting the above technical solution, after the rib is fixed, the connection points between the rib, the mounting part, and the wheel hub body are triangularly distributed, which helps to improve the structural strength.

[0019] Preferably, the rib includes a reinforcing rib and a graphene layer disposed on the outer layer of the reinforcing rib, the graphene layer abutting against the spoke.

[0020] By adopting the above technical solution, it is beneficial to improve the heat dissipation efficiency of the rib. By using the graphene layer to contact the spokes, mounting parts and wheel hub body, it is beneficial to improve the heat dissipation efficiency of the wheel hub.

[0021] The outstanding advantages of this utility model compared to the prior art are:

[0022] 1. The present invention sets the rib in a ring shape and abuts against the spokes on both sides, which is conducive to quickly dispersing stress, reducing stress concentration, and thus making the rib less prone to damage;

[0023] 2. When the bolt loosens and the bolt head moves away from the reinforcing rib, the sealing block and the needle detach from the indicator bladder. The indicator liquid in the indicator bladder flows out through the hole pierced by the needle and stains the surface of the rib, which helps to detect the bolt loosening in time.

[0024] 3. After the rib is fixed, the connection points between the rib, the mounting part, and the wheel hub body are triangularly distributed, which helps to improve the structural strength. Attached image description:

[0029] The present invention will be further described below with reference to specific embodiments:

[0030] This application discloses a wheel hub with detachable ribs, see [link to relevant documentation]. Figure 1The wheel includes a hub body 1 and a spoke plate 2. The spoke plate 2 includes a mounting part 21 and a plurality of spokes 22. The mounting part 21 is used to fix it to the drive shaft. The number of spokes 22 is 5. The plurality of spokes 22 are distributed at equal intervals around the mounting part 21. The axis of the hub body 1 and the axis of the mounting part 21 are coaxial. The hub body 1 is arranged around the mounting part 21. The hub body 1 and the mounting part 21 are fixed by the spokes 22. The hub body 1, the mounting part 21 and the spokes 22 are integrally formed.

[0031] See Figure 1 A number of ribs 3 are detachably connected between the hub body 1 and the mounting part 21 via screws 4. The number of ribs 3 is 5. The ribs 3 are evenly distributed around the outer periphery of the mounting part 21, and the ribs 3 are located between adjacent spokes 22.

[0032] See Figure 1 and Figure 2 The rib 3 is ring-shaped, with one end of the rib 3 near the mounting part 21 being fan-shaped and fixedly connected to the mounting part 21. The two side walls of the rib 3 near the mounting part 21 abut against the side walls of the adjacent spokes 22. The rib 3 has three mounting holes 311. One mounting hole 311 is located at the end of the rib 3 near the mounting part 21, through which the screw 4 passes and is threaded to the mounting part 21. The other two mounting holes 311 correspond to the inner ring edge of the hub body 1, through which the screw 4 passes and is threaded to the hub body 1. The three mounting holes 311 are triangularly distributed, which helps to improve connection stability and structural strength.

[0033] See Figure 1 and Figure 2 The rib 3 includes a reinforcing rib 31 and a graphene layer 32. The screw 4 passes through the mounting port 311 on the reinforcing rib 31 and is threadedly connected to the mounting part 21 or the wheel hub body 1. The graphene layer 32 covers the surface of the reinforcing rib 31 and abuts against the adjacent spokes 22, which helps to improve the heat dissipation of the wheel hub.

[0034] See Figure 1 and Figure 2 The screw 4 includes an integrally machined rod body 41 and a screw head 42. The rod body 41 has an external thread for threaded connection with the mounting part 21 or the wheel hub body 1. The screw head 42 is located at the end of the rod body 41. An elastic washer 411 is fitted on the rod body 41. The elastic washer 411 is located on the side of the reinforcing rib 31 near the mounting part 21 or the wheel hub body 1. The reinforcing rib 31 is pressed against the mounting part 21 or the wheel hub body 1 by the elastic washer 411.

[0035] See Figure 1 and Figure 2The reinforcing rib 31 has several grooves 312. The position and number of grooves 312 correspond one-to-one with the position and number of mounting openings 311. After the reinforcing rib 31 is inserted into the rod body 41, the screw head 42 is inserted into the groove 312.

[0036] See Figure 2 and Figure 3 The reinforcing rib 31 is embedded with a warning sac 5. The position and number of warning sacs 5 correspond one-to-one with the position and number of mounting ports 311. The warning sacs 5 are arranged circumferentially around the corresponding mounting ports 311. When the screw head 42 is inserted into the recess 312, the warning sac 5 is located on the side of the screw head 42 closer to the rod body 41. The warning sac 5 contains a warning liquid. In this embodiment, the warning liquid is red and contains a fluorescent agent to make the warning more eye-catching.

[0037] See Figure 2 and Figure 3 The screw head 42 has several spikes 421 machined at one end near the shaft 41. The spikes 421 are tapered away from the screw head 42 and are distributed circumferentially around the shaft 41. The spikes 421 protrude from the surface of the screw head 42 and are used to pierce the warning sac 5. Several sealing blocks 422 are fixed at one end of the screw head 42 near the shaft 41. The position and number of sealing blocks 422 correspond one-to-one with the position and number of spikes 421. The sealing blocks 422 are arranged around the outer periphery of the corresponding spikes 421 and fit against the corresponding spikes 421. The end of the spike 421 away from the screw head 42 protrudes from the sealing block 422.

[0038] During installation, the rod 41 passes through the mounting port 311 and is threadedly connected to the mounting part 21 or the wheel hub body 1 screw 4. The screw head 42 is inserted into the recess 312. After the rod 41 is locked, the screw head 42 presses against the bottom inner wall of the recess 312, causing the spike 421 to pierce the warning sac 5. The sealing block 422 seals the pierced gap of the warning sac 5. If the screw 4 becomes loose, the screw head 42 will move the spike 421 and the sealing block 422 away from the warning sac 5. During vehicle operation, the wheel hub rotates, causing the warning fluid in the warning sac 5 to flow out through the pierced opening of the spike 421 and adhere to the surface of the rib 3, making it easy to detect when the screw 4 becomes loose.

[0039] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
