Description

Technical Field

[0001] This utility model relates to the field of automotive wheel hub technology, specifically to a sand-proof automotive wheel hub suitable for desert environments. Background Technology

[0002] Desert regions are characterized by high temperatures, abundant sand and dust, and strong wind erosion, which places high demands on car wheel rims. Fine sand can easily enter the wheel rim through the gaps, causing wear on the braking system and failure of bearing seals. Furthermore, when off-roading, traditional wheel rims cannot effectively lock the tire bead, leading to the risk of wheel rim coming off the rim. Therefore, it is necessary to design a sand-proof car wheel rim suitable for desert environments.

[0003] Fine sand can enter the wheel hub through the gaps, causing abnormal wear of the braking system, failure of bearing seals, and even affecting the accuracy of wheel speed sensors. Sand-proof devices need to be installed to prevent sand from entering. In addition, existing wheel hubs usually require lower tire pressure to increase the tire contact area. Soft sand causes the wheels to sink and bounce frequently, generating severe radial impact loads, which will greatly increase the risk of tires coming off the bead and affect the health and safety of people during off-roading. Utility Model Content

[0004] The technical problem to be solved by this utility model is as follows: to provide a sand-proof car wheel hub suitable for desert environments, which is highly practical, easy to operate, and has a simple structure. This solves the problems mentioned in the background art, such as fine sand entering the wheel hub through the wheel hub gap, causing abnormal wear of the braking system, failure of bearing seals, and even affecting the accuracy of wheel speed sensors. It also addresses the need to install sand-proof devices to prevent sand from entering, and the fact that existing wheel hubs usually require lower tire pressure to increase the tire contact area. In soft sand, the wheels frequently sink and bounce, generating severe radial impact loads, which greatly increases the risk of tire derailment and affects the health and safety of personnel during off-road driving.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A sand-proof car wheel hub suitable for desert environments includes a wheel hub with a pressure plate fixedly connected to its interior recess. A sand-proof mechanism is threadedly connected to the back of the center of the pressure plate. A fixing ring is fixedly connected to the circumference of the wheel hub, and an anti-detachment mechanism is threadedly connected to the interior of the fixing ring. The sand-proof mechanism includes a central frame threadedly connected to the back of the center of the pressure plate, sand-proof rings fixedly connected to the periphery of the central frame, and a cover plate fixedly connected to the back of the sand-proof rings. The anti-detachment mechanism includes an anti-detachment bolt threadedly connected to the interior of the fixing rings, an anti-detachment ring threadedly connected to the front end of the anti-detachment bolt, a pressure ring fixedly connected to the periphery of the back of the anti-detachment ring, and an anti-detachment channel provided at the rear of the outer side of the wheel hub.

[0007] As a further embodiment of this utility model: the anti-detachment channel is provided with a number of arc-shaped grooves inside, and a retaining ring is provided on the right side of the arc-shaped groove. The retaining ring serves to block and prevent the ring from detaching from the inner side.

[0008] As a further embodiment of this utility model: the inner side of the pressure ring is provided with a slot, which is engaged with the top surface of the fixing ring around the perimeter. The pressure ring serves to clamp the external tire and prevent it from coming off the bead.

[0009] As a further embodiment of this utility model: a cavity is provided in the middle of the wheel hub, and an air outlet valve is installed on the bottom surface of the cavity. An air limiting pipe is fixedly connected to the bottom of the air outlet valve. The air limiting pipe helps to limit the amount of gas lost from the tire.

[0010] As a further embodiment of this utility model: an adjusting plug is installed on the top surface of the gas limiting tube, and a handle is fixedly connected to the top surface of the adjusting plug. The adjusting plug is used to adjust the gas flow rate by turning it.

[0011] As a further embodiment of this utility model: an adjusting plate is fixedly connected to the bottom of the adjusting bolt, and the adjusting plate is slidably connected to the inside of the gas limiting tube around its perimeter. By setting the adjusting plate, the gas flow rate is adjusted according to the different depths into the gas limiting tube.

[0012] As a further embodiment of this utility model: a protective cover is fixedly connected to the middle of the anti-detachment ring, and a protective cap is threadedly connected to the middle of the protective cover. The protective cap provides multiple layers of protection and heat dissipation.

[0013] The beneficial effects of this utility model are:

[0014] 1. Through the sand-proof mechanism, a pressure plate is installed inside the wheel hub when it is to be used for sand off-roading. A mid-frame is installed on the back of the pressure plate, which also provides partial support in the middle. Sand-proof rings and cover plates are installed on the outside of the mid-frame. The cover plate prevents sand from entering the wheel hub from the back. A hole is opened in the middle of the cover plate so that the axle of the external vehicle can pass through and be installed, which prevents sand from entering and avoids sand from entering the wheel hub through the wheel hub gap, which would cause brake system wear and bearing seal failure.

[0015] 2. With the anti-rollover mechanism in place, when the wheel rim is to be used for sand off-roading, first install the outer tire around the rim, then install the anti-rollover ring on the side of the rim using anti-rollover bolts. The pressure ring on the back of the anti-rollover ring is locked onto the top surface of the fixing ring, squeezing the outer tire into it. Since an anti-rollover channel is also installed on the outer rear of the rim, this process is carried out simultaneously from the inside, preventing the outer tire from coming off the rim. This reinforces the outer tire and prevents it from coming off the rim, avoiding the risk of the tire sinking and bouncing frequently due to low tire pressure and soft sand, which would generate severe radial impact loads and significantly increase the risk of the tire coming off the rim, affecting the health and safety of personnel during off-roading.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4As shown, a sand-proof car wheel hub suitable for desert environments includes a wheel hub 1. A pressure plate 2 is fixedly connected to the recessed part of the wheel hub 1. A sand-proof mechanism 3 is threadedly connected to the back of the center of the pressure plate 2. A fixing ring 4 is fixedly connected to the circumference of the wheel hub 1. An anti-detachment mechanism 5 is threadedly connected to the inside of the fixing ring 4. The sand-proof mechanism 3 includes a central frame 301 threadedly connected to the back of the center of the pressure plate 2. Sand-proof rings 302 are fixedly connected to the periphery of the central frame 301. A cover plate 303 is fixedly connected to the back of the sand-proof rings 302. The pressure plate 2 is installed inside the wheel hub 1, and the central frame 301 is installed on the back of the pressure plate 2. The central frame 301 also provides partial support in the middle. The sand-proof rings 302 and the cover plate 303 are installed around the periphery of the central frame 301. The cover plate 303 prevents sand from entering the wheel hub 1 from the back. A hole is opened in the center of the cover plate 303 to allow the external axle of the car to pass through. The anti-detachment mechanism 5 includes an anti-detachment bolt 501 threaded into the inside of the fixing ring 4. An anti-detachment ring 502 is threaded to the front end of the anti-detachment bolt 501. A pressure ring 503 is fixedly connected to the outer periphery of the back of the anti-detachment ring 502. An anti-detachment channel 504 is provided at the rear of the outer side of the wheel hub 1. First, the outer tire is installed around the wheel hub 1. Then, the anti-detachment ring 502 is installed on the side of the wheel hub 1 through the anti-detachment bolt 501. Because the pressure ring 503 on the outer periphery of the back of the anti-detachment ring 502 is stuck on the top surface of the fixing ring 4, the outer tire is squeezed into it. Since the anti-detachment channel 504 is also installed at the rear of the outer side of the wheel hub 1, the process is carried out simultaneously inside, preventing the outer tire from detaching and reinforcing the outer tire to prevent it from detaching. This avoids the tire pressure drop, which can cause the wheel to sink and bounce frequently on soft sand, generating severe radial impact loads, which will greatly increase the risk of the tire detaching and affect the health and safety of personnel during off-roading.

[0024] The anti-slip channel 504 has several arc-shaped grooves 6 inside. The arc-shaped grooves 6 can increase resistance and prevent the outer tire from sliding. A retaining ring 7 is provided on the right side of the arc-shaped grooves 6. The retaining ring 7 can prevent the inner tire from slipping off.

[0025] The inner side of the pressure ring 503 is provided with a groove, which facilitates the compression and fixing of the outer tire to prevent it from coming off. The groove is engaged with the top surface of the fixing ring 4 around the perimeter.

[0026] A cavity is provided in the middle of the hub 1, and an air outlet valve 8 is installed on the bottom surface of the cavity. The air outlet valve 8 facilitates the release of air to change the tire pressure. An air limiting pipe 9 is fixedly connected to the bottom of the air outlet valve 8, and the air limiting pipe 9 facilitates the adjustment of the air flow rate.

[0027] An adjusting plug 10 is installed on the top surface of the air limiting pipe 9. The adjusting fan 10 facilitates the adjustment of the airflow size. A handle 11 is fixedly connected to the top surface of the adjusting plug 10. The handle 11 facilitates operation and adjustment.

[0028] An adjusting plate 12 is fixedly connected to the bottom of the adjusting plug 10. The adjusting plate is convenient for limiting the flow direction and speed of the airflow. The adjusting plate 12 is slidably connected to the inside of the air limiting tube 9 around its perimeter.

[0029] The anti-loosening ring 502 is fixedly connected to a protective cover 13 in the middle, and the protective cover 13 is threadedly connected to a protective cap 14 in the middle. The protective cap 14 is used to protect the internal bolts from being eroded by sand.

[0030] The working principle of this utility model is as follows: A pressure plate 2 is installed inside the wheel hub 1. A middle frame 301 is installed on the back of the pressure plate 2. The middle frame 301 also plays a role in providing partial support in the middle. A sand-proof ring 302 and a cover plate 303 are installed around the middle frame 301. The cover plate 303 prevents sand from entering the wheel hub 1 from the back. A hole is opened in the middle of the cover plate 303 so that the external car axle can pass through and be installed.

[0031] First, the outer tire is installed around the rim 1. Then, the anti-loosening ring 502 is installed on the side of the rim 1 through the anti-loosening bolt 501. Because the pressure ring 503 on the outer periphery of the back of the anti-loosening ring 502 is stuck on the top surface of the fixing ring 4, the outer tire is squeezed into it. Since the anti-loosening channel 504 is also installed on the rear of the outer side of the rim 1, it works simultaneously inside to prevent the outer tire from coming off the rim. This strengthens the outer tire and prevents it from coming off the rim. It avoids the tire pressure dropping, which can cause the wheel to sink and bounce frequently on soft sand, generating a severe radial impact load. This would greatly increase the risk of the tire coming off the rim and affect the health and safety of the personnel during off-roading.

[0032] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
