Technical fields:

[0001] This utility model belongs to the technical field of wheel hubs, and specifically refers to a car wheel hub with protective components. Background technology:

[0002] A wheel hub, also known as a rim, rim, wheel, or rim, is a cylindrical metal component that supports the tire from within and is mounted on a central axle.

[0003] As an important component of automobiles, wheel hubs are mostly fixed to the drive shaft of the car with bolts. Most of these bolts are exposed, and their surfaces are deformed by wind, sand, and rain, increasing the difficulty of disassembling the wheel hub during maintenance. This needs to be improved. Summary of the Invention:

[0004] The purpose of this invention is to provide an automotive wheel hub with protective components to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows:

[0006] A car wheel hub with a protective component includes a wheel hub body, a shaft hole for connecting a car drive shaft is provided on the wheel hub body, a positioning convex ring is provided on the wheel hub body, the shaft hole is located in the inner ring of the positioning convex ring, a protective component is threadedly connected to the positioning convex ring, the protective component covers the shaft hole, and a plurality of support rods are provided on the protective component, the support rods connecting the wheel hub body and the protective component.

[0007] Preferably, the protective assembly includes a protective cover threaded to the positioning protrusion ring and a connecting ring rotatably connected to the protective cover. The protective cover covers the shaft hole, and a plurality of the support rods are connected to the connecting ring. The support rods are rotatably connected to the protective cover through the connecting ring.

[0008] Preferably, the support rod includes a first rod disposed on the connecting ring and a second rod slidably connected to the first rod. The second rod slidably extends into or out of the end of the first rod away from the positioning convex ring. The hub body is provided with a plurality of positioning grooves, which are correspondingly disposed with the second rod. The positioning grooves are used for the corresponding second rod to be engaged and positioned. The positioning convex ring is provided with a driving member, which drives the second rod to move and engage.

[0009] Preferably, the driving component is a magnetic block, and a magnet is embedded in the second rod. The magnet is arranged around the outer periphery of the magnetic block, and the N pole of the magnetic block and the magnet are located in the same plane. The magnetic pole of the magnet near one end of the magnetic block is the N pole.

[0010] Preferably, the first rod is provided with a heat-expanding block, which expands under heat and abuts against the second rod.

[0011] Preferably, the protective cover has a groove for the magnetic block to be inserted into, and the magnetic block has a baffle that covers the groove.

[0012] Preferably, a ball bearing is rotatably connected to the connecting ring, and the ball bearing abuts against the inner wall of the convex ring.

[0013] Preferably, the hub body includes an axle, a plurality of spokes disposed on the axle, and a rim disposed on the spokes, wherein the projections of the spokes and the support rod in a direction parallel to the axis of the axle do not coincide.

[0014] The outstanding advantages of this utility model compared to the prior art are:

[0015] 1. After the axle is installed to the wheel hub body by bolts, the protective component and the support rod are installed on the wheel hub body. The protective component covers the axle hole to protect the bolts, which helps to reduce bolt wear and facilitates bolt removal. Furthermore, by placing the support rod on the outside of the wheel hub body, it makes it less likely for sand and gravel to leave scratches on the wheel hub body.

[0016] 2. This utility model uses a magnetic block. After fixing the protective cover and the positioning protrusion ring, the connecting ring is rotated to align the second rod with the corresponding positioning groove. Then, the magnetic block is installed on the protective cover. The magnetic sticker on the second rod and the magnetic block are like poles that repel each other, driving the second rod to move and extend the first rod into the positioning groove. When it is necessary to remove the protective component, the magnetic block is taken out to disengage the second rod from the positioning groove. Then, the protective cover can be rotated to remove it, which helps to improve the efficiency of wheel hub disassembly and assembly.

[0017] 3. After assembly, the support rod is connected to the wheel hub body by the magnetic force between the second rod and the magnetic block. By setting a heat-expanding block on the first rod, the temperature at the wheel hub rises during vehicle operation, causing the heat-expanding block to deform and abut against the second rod, which helps to improve the support force of the support rod during vehicle operation.

[0023] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —4:

[0024] This application discloses a car wheel hub with protective components. See also: A car wheel hub with protective components. Figure 1 and Figure 2 The wheel hub body 1 includes an axle 11, several spokes 12, and a rim 13. The axle 11 and the rim 13 are coaxially arranged. The spokes 12 are evenly distributed at equal intervals around the outer circumference of the axle 11. The opposite ends of the spokes 12 are fixedly connected to the axle 11 and the rim 13, respectively. The axle 11 has a shaft hole 111 for connecting the axle. A positioning protrusion ring 112 is fixed on the axle 11. The positioning protrusion ring 112 is located on the outside of the wheel hub body 1 and is arranged around the outer circumference of the shaft hole 111. The positioning protrusion ring 112 is arranged around the outer circumference of the axle. The bolt for connecting the axle is located inside the inner ring of the positioning protrusion ring 112.

[0025] See Figure 1 and Figure 2 A protective component 2 is threadedly connected to the positioning protrusion ring 112. The protective component 2 includes a protective cover 21 and a connecting ring 22. The protective cover 21 is located on the side of the positioning protrusion ring 112 away from the wheel axle 11. An external thread is machined on the outer ring surface of the positioning protrusion ring 112. The protective cover 21 is fixed to the positioning protrusion ring 112 by the external thread, and the protective cover 21 covers the end of the positioning protrusion ring 112 away from the wheel axle 11. An annular groove 211 is formed on the protective cover 21, into which the connecting ring 22 is inserted. The rotation axis of the connecting ring 22 is coaxial with the axis of the wheel axle 11, and the connecting ring 22 is rotatably connected to the positioning protrusion ring 112. A plurality of balls 221 are rotatably connected to the connecting ring 22. The balls 221 are evenly distributed on the connecting ring 22 at equal intervals. The balls 221 abut against the inner wall of the annular groove 211, which helps to reduce the contact area between the connecting ring 22 and the protective cover 21, and thus reduces the friction between them.

[0026] See Figure 1 and Figure 2 A plurality of support rods 3 are fixed on the connecting ring 22. The support rods 3 are located on the side of the positioning convex ring 112 away from the wheel axle 11. The support rods 3 are rotatably connected to the protective cover 21. The support rods 3 are evenly distributed at equal intervals around the outer circumference of the connecting ring 22. The projection of the support rods 3 in the direction parallel to the axis of the wheel axle 11 does not coincide with the projection of the spokes 12 in the direction parallel to the axis of the wheel axle 11. A plurality of positioning grooves 131 are provided on the rim 13. The position and number of the positioning grooves 131 correspond one-to-one with the position and number of the support rods 3. The positioning grooves 131 are for the corresponding positioning rods to be engaged.

[0027] By installing the support rod 3 on the outside of the spokes 12, it shields the spokes from flying gravel during driving, which helps reduce scratches on the spokes 12 and improves the service life of the wheel hub body 1. Furthermore, the support rod 3 is rotatably connected to the protective cover 21 via the connecting ring 22, which helps reduce the torque at the support rod 3 during vehicle operation and further improves its service life.

[0028] See Figure 1 and Figure 3 The support rod 3 includes rod 1 31 and rod 2 32. Rod 1 31 is fixedly connected to the connecting ring 22. Rod 1 31 is distributed at equal intervals around the outer circumference of the connecting ring 22. Rod 2 32 is located on the side of the corresponding rod 1 31 away from the connecting ring 22. A sliding groove 311 is opened at the end of rod 1 31 away from the connecting ring 22. The sliding groove 311 is for rod 2 32 to be inserted into. Rod 2 32 slides into or out of the sliding groove 311. The sliding direction of rod 2 32 is parallel to the length direction of rod 1 31. A positioning groove 131 is for rod 2 32 to be inserted into. A driving component 4 is installed on the protective cover 21. The driving component 4 drives several rods 2 32 to move.

[0029] See Figure 3 and Figure 4 The driving component 4 is a magnetic block 41. The protective cover 21 has a groove 212 on the side away from the wheel axle 11. The groove 212 is for the magnetic block 41 to be inserted. The magnetic block 41 has N pole and S pole. The N pole is located on the same plane as several rods 32. The rods 32 are evenly distributed around the outer periphery of the N pole of the magnetic block 41. A magnet 321 is embedded in the rod 32. The distribution direction of the N pole and S pole of the magnet 321 is parallel to the sliding direction of the rod 32. The N pole of the magnet 321 is close to the protective cover.

[0030] When the magnetic block 41 is inserted into the groove 212, the second rod 32 tends to extend out of the first rod 31 under the action of magnetism. Rotating the first rod 31 moves the second rod 32. When the second rod 32 moves to the positioning port, it is locked into the positioning groove 131. When the hub body 1 needs to be repaired, the magnetic block 41 is moved to disengage from the protective cover 21, and then the second rod 32 is moved to extend into the first rod 31 to disengage from the positioning groove 131, thus releasing the positioning of the support rod 3.

[0031] A baffle 411 is fixed on the magnetic block 41. The baffle 411 is located on the side of the magnetic block 41 away from the wheel axle 11. The baffle 411 covers the groove 212, which helps to reduce the entry of iron filings on the road into the gap between the magnetic block 41 and the protective cover 21.

[0032] See Figure 1 and Figure 3 A thermal expansion block 33 is fixed on rod 31, and the thermal expansion block 33 is located in the sliding groove 311. After the support rod 3 is installed and fixed to the wheel hub body 1, the thermal expansion block 33 is spaced apart from rod 32. As the vehicle speed increases, the thermal expansion block 33 expands due to heat and abuts against rod 32, supporting rod 32, which helps to improve the support capacity and structural stability of the support rod 3.

[0033] The implementation principle of a car wheel hub with protective components in this application embodiment is as follows: by installing protective components 2 on the outside of the wheel hub body 1, the bolts used to connect the axle are protected, so that the bolts are not exposed, which helps to reduce the wear on the bolt surface and facilitates the disassembly of the bolts during maintenance.

[0034] 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.
