Description

A wear-resistant wheel hub Technical Field

[0001] The utility model relates to the technical field of wheel hubs, in particular to a wear-resistant wheel hub. Background Art

[0002] The wheel hub is a modular product composed of a variety of metal castings, bearings, and lubricants. When the vehicle is driving, a large amount of heat will be generated, and the temperature affects the viscosity change and lubrication effect of the grease. If the wheel hub bearing is not lubricated in time, it will cause serious damage to the wheel hub bearing.

[0003] In the current existing technology, lubricating oil is generally injected into the wheel hub bearings at intervals of several months or even longer to ensure the lubrication level of the wheel hub bearings. However, when a vehicle travels a long distance in a short period of time, a large amount of lubricating oil will be consumed. Therefore, users can easily neglect to inject lubricating oil into the wheel hub bearings, resulting in serious wear of the wheel hub bearings, and further causing the wheel hub to be easily damaged during driving. Therefore, a wear-resistant wheel hub is designed and produced here to solve the above problem. Utility Model

[0004] The purpose of the present utility model is to provide a wear-resistant wheel hub to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a wear-resistant wheel hub, comprising an outer ring and a mounting shaft, a plurality of reinforcing rods fixed between the outer ring and the mounting shaft, a bearing sleeved inside the mounting shaft, an oiling nozzle fixed to the side wall of the mounting shaft, an oil storage tank fixed to the surface of the reinforcing rod, an oil storage cavity provided inside the oil storage tank, lubricating oil provided inside the oil storage cavity, a push plate movably installed inside the oil storage cavity, an oil pipe installed between the oil outlet of the oil storage tank and the oiling nozzle, and a spring fixed between the side surface of the push plate away from the oil pipe and the side wall of the oil storage cavity.

[0006] Preferably, the push plate separates the oil storage chamber into an air intake chamber and a lubrication chamber, and the lubricating oil is arranged inside the lubrication chamber.

[0007] Preferably, an air intake valve is fixed to a side wall of the oil storage tank away from the oil pipe, and the air intake valve is connected to the air intake cavity.

[0008] Preferably, an oil filling port is fixed on the surface of the oil storage tank, and the oil filling port is arranged corresponding to the lubrication cavity.

[0009] Preferably, a sealing ring is installed at the mouth of the installation shaft, and the sealing ring is arranged above the mouth of the oil filling nozzle.

[0010] Preferably, three groups of reinforcing rods are provided, and adjacent reinforcing rods are arranged at equal distances.

[0011] Preferably, the oil injection nozzle is located directly above the bearing.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model is a wear-resistant wheel hub. Lubricating oil is arranged in the oil storage chamber. Under the action of centrifugal force generated by the rotation of the wheel hub, the push plate squeezes the lubricating oil into the inside of the bearing, thereby lubricating the bearing. It can prevent the bearing from being worn and damaged due to a large amount of heat generated during the rotation process, greatly improving the service life of the wheel hub bearing, and further preventing the life of the wheel hub from being reduced due to damage to the bearing, making the wheel hub more wear-resistant.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please refer to Figures 1-4. This embodiment provides a wear-resistant wheel hub, including an outer ring 1 and a mounting shaft 2, a plurality of reinforcing rods 3 are fixed between the outer ring 1 and the mounting shaft 2, a bearing 4 is sleeved inside the mounting shaft 2, an oiling nozzle 5 is fixed to the side wall of the mounting shaft 2, an oil storage tank 6 is fixed on the surface of the reinforcing rod 3, an oil storage chamber 7 is provided inside the oil storage tank 6, lubricating oil is provided inside the oil storage chamber 7, a push plate 8 is movably installed inside the oil storage chamber 7, an oil pipe 10 is installed between the oil outlet of the oil storage tank 6 and the oiling nozzle 5, and a spring 9 is fixed between the side surface of the push plate 8 away from the oil pipe 10 and the side wall of the oil storage chamber 7.

[0021] By adopting the above technical solution, when the vehicle is running, the wheel hub will rotate rapidly, and the wheel hub will generate a large centrifugal force during the rotation. Under the action of centrifugal force, the push plate 8 will move along the oil storage chamber 7 toward the outer ring 1. Lubricating oil is provided inside the oil storage chamber 7. During the movement of the push plate 8 toward the outer ring 1, the lubricating oil will be squeezed. After being squeezed, the lubricating oil will enter the oil injection nozzle 5 along the oil pipe 10, and finally squeezed out from the oil injection nozzle 5 to the inside of the bearing 4, completing the lubrication of the bearing 4. It can prevent the bearing 4 from being worn and damaged due to the large amount of heat generated during the rotation process, greatly improving the service life of the wheel hub bearing 4, and then preventing the wheel hub from reducing its service life due to damage to the bearing 4, making the wheel hub more wear-resistant.

[0022] Furthermore, the push plate 8 separates the oil storage chamber 7 into an air intake chamber and a lubrication chamber, and the lubricating oil is arranged inside the lubrication chamber.

[0023] By adopting the above technical solution, it should be noted that the sealing arrangement between the push plate 8 and the oil storage chamber 7 can prevent the lubricating oil from entering the air intake chamber from the lubricating chamber.

[0024] Furthermore, an air intake valve 12 is fixed to a side wall of the oil storage tank 6 away from the oil pipe 10 , and the air intake valve 12 is communicated with the air intake cavity.

[0025] Furthermore, an oil filling port 11 is fixed on the surface of the oil storage tank 6 , and the oil filling port 11 is arranged corresponding to the lubrication cavity.

[0026] By adopting the above technical solution, the intake valve 12 can ensure that the push plate 8 moves toward the outer ring 1 under the action of centrifugal force, and the spring 9 is provided to connect and limit the push plate 8. When the lubricating oil inside the lubrication chamber is used up, it is ensured that the push plate 8 will not go beyond the oil filling port 11, thereby ensuring that the lubricating oil can be smoothly injected into the lubrication chamber.

[0027] Furthermore, a sealing ring 13 is installed at the mouth of the mounting shaft 2 , and the sealing ring 13 is arranged above the mouth of the oiling nozzle 5 .

[0028] Furthermore, three groups of reinforcing rods 3 are provided, and adjacent reinforcing rods 3 are arranged at equal distances.

[0029] Furthermore, the mouth of the oiling nozzle 5 is located directly above the bearing 4 .

[0030] By adopting the above technical solution, when the vehicle stops, the push plate 8 is not affected by centrifugal force, and the spring 9 can restore the push plate 8 to its original position. When the push plate 8 returns to its original position, since the interior of the mounting shaft 2 is not in a vacuum state during driving, the lubricating oil injected into the bearing 4 will not be re-sucked into the oil storage chamber 7.

[0031] Working principle: When the vehicle is driving, the wheel hub will generate a large centrifugal force during the rotation process. Under the action of centrifugal force, the push plate 8 will move along the oil storage chamber 7 toward the outer ring 1. Lubricating oil is provided inside the oil storage chamber 7. During the movement of the push plate 8 toward the outer ring 1, the lubricating oil will be squeezed. After being squeezed, the lubricating oil will enter the oil injection nozzle 5 along the oil pipe 10, and finally squeezed out from the oil injection nozzle 5 to the inside of the bearing 4, completing the lubrication of the bearing 4.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
