Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a quick-release wheel hub structure. Background Art

[0002] With the development and progress of society, various vehicles have been widely popularized, and wheels, as the main components of vehicles, play a vital role in the comfort and safety of vehicles during driving. The wheel hub is a barrel-shaped metal component that supports the tire with its inner profile and is centrally mounted on the axle.

[0003] When removing or installing a tire, the traditional wheel hub installation or removal process often requires professional tools and a certain amount of time, which is inconvenient for users who need to frequently change tires or perform wheel maintenance. Professional tools and personnel are also required to operate, and traditional wheel hubs have many parts that cannot be quickly installed and removed. Therefore, further improvements can be made. Utility Model Content

[0004] To solve the above-mentioned problems, the utility model provides the following technical solutions: a quick-release wheel hub structure, comprising a wheel hub body, wherein the wheel hub body is composed of a wheel hub main side and a wheel hub locking side, a card slot is provided on the side of the wheel hub main side close to the wheel hub locking side, a guide slot is provided on the outer wall of the wheel hub main side close to the card slot, a buckle is fixedly installed on the inner wall of the wheel hub locking side corresponding to the card slot, the buckle passes through the card slot and is rotatably connected in the guide slot, and a lubrication assembly is provided inside the front side of the wheel hub.

[0005] As an optimization, a limiting groove is provided on the inner wall of the guide groove, and the limiting groove is provided corresponding to the size and position of the buckle. The buckle is located at the limiting groove by rotating the wheel hub locking edge, and then the buckle is driven into the limiting groove by inflating the tire, thereby limiting the main edge of the wheel hub and the wheel hub locking edge.

[0006] As an optimization, the lubrication assembly includes a liquid storage tank fixedly installed inside the main side of the wheel hub, the bottom end of the liquid storage tank is connected to a liquid guide tube, and the other end of the liquid guide tube is connected to the connection between the wheel hub and the rotating shaft.

[0007] As an optimization, a sealing seat is fixedly installed at the center of the bottom wall of the liquid storage tank corresponding to the liquid guide tube, a limiting cylinder is fixedly installed inside the liquid storage tank, a fixed cylinder is fixedly installed inside the limiting cylinder, a sealing block is slidably connected inside the bottom of the limiting cylinder, a connecting rod is fixedly installed on the top side of the sealing block, a counterweight ball is fixedly installed on the other end of the connecting rod, and a compression spring is fixedly installed between the sealing block and the fixed cylinder.

[0008] As an optimization, the sealing block is embedded in the opening of the sealing seat, the connecting rod is slidably inserted in the fixed cylinder, and the counterweight ball is slidably connected in the limit cylinder. The movement of the car will drive the wheel hub to rotate, and the counterweight ball will tend to move outward under the action of centrifugal force, thereby driving the sealing block to slide into the limit cylinder, so the opening of the sealing seat is no longer blocked, so that the lubricating fluid in the liquid storage tank can flow to the shaft connection, thereby avoiding long-term lack of lubricating fluid to damage the wheel hub and the shaft.

[0009] As an optimization, the compression spring sleeve is arranged on the outside of the connecting rod, and the sealing block is made of rubber material. The elastic force of the compression spring itself will drive the sealing block to be stuck into the opening of the sealing seat, and then always block the opening in the absence of external force to prevent leakage of the lubricating fluid.

[0010] The beneficial effects of the utility model are:

[0011] 1. The quick-release wheel hub structure aligns the buckle on the wheel hub locking edge with the gap of the slot on the main side of the wheel hub, and then moves the buckle along the guide groove by rotating until the wheel hub locking edge is rotated to the bottom of the guide groove and cannot rotate. Then, the assembly work can be completed. After that, by inflating the tire, the buckle can be inserted into the limit groove through the expansion of the tire, so that the main side of the wheel hub and the wheel hub locking edge cannot rotate relative to each other, thereby achieving the effect of preventing loosening. In addition, it can be quickly installed and disassembled without using professional tools, thereby improving user convenience.

[0012] 2. The quick-release hub structure makes it easier to remove the hub for cleaning and maintenance, thereby extending the service life of the hub. Different types of tires can also be quickly replaced according to different riding conditions such as road conditions or weather conditions, thereby improving adaptability and flexibility.

[0013] 3. The quick-release hub structure drives the sealing block to be stuck into the opening of the sealing seat through the elastic force of the compression spring, and then always blocks the opening without external force to prevent leakage of the lubricating fluid. When the hub rotates, the counterweight ball drives the sealing block to slide into the limit cylinder under the action of centrifugal force, and then the opening of the sealing seat is no longer blocked, so that the lubricating fluid in the liquid storage tank can flow to the shaft connection, thereby avoiding long-term lack of lubricating fluid to damage the hub and the shaft, and extending their service life.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-6 A quick-release wheel hub structure includes a wheel hub body 1, which is composed of a wheel hub main side 2 and a wheel hub locking side 3. A card slot 4 is provided on one side of the wheel hub main side 2 near the wheel hub locking side 3, and a guide slot 5 is provided on the outer wall of the wheel hub main side 2 near the card slot 4. A buckle 6 is fixedly installed on the inner wall of the wheel hub locking side 3 corresponding to the card slot 4. The buckle 6 passes through the card slot 4 and is rotatably connected in the guide slot 5. A lubrication component is provided inside the front of the wheel hub, and a limiting groove 7 is provided on the inner wall of the guide groove 5, and the limiting groove 7 is provided corresponding to the size and position of the buckle 6. The buckle 6 is located at the limiting groove 7 by rotating the wheel hub locking side 3, and then the buckle 6 can be driven to be clamped into the limiting groove 7 by inflating the tire, thereby limiting the main side 2 of the wheel hub and the wheel hub locking side 3.

[0025] See also Figure 7-8The lubrication assembly includes a liquid storage tank 8 fixedly installed inside the main side 2 of the wheel hub, the bottom end of the liquid storage tank 8 is connected with a liquid guide tube 9, and the other end of the liquid guide tube 9 is connected to the connection between the wheel hub and the rotating shaft, a sealing seat 10 is fixedly installed at the center of the bottom wall of the liquid storage tank 8 corresponding to the liquid guide tube 9, a limiting cylinder 11 is fixedly installed inside the liquid storage tank 8, a fixed cylinder 12 is fixedly installed inside the limiting cylinder 11, a sealing block 13 is slidably connected inside the bottom of the limiting cylinder 11, the sealing block 13 is embedded in the opening of the sealing seat 10, and a connecting Rod 14, connecting rod 14 is slidably inserted in the fixed cylinder 12, and the other end of connecting rod 14 is fixedly installed with a balancing ball 15, which is slidably connected in the limiting cylinder 11. The wheel hub is driven to rotate by the running of the car, and then the balancing ball 15 has a tendency to move outward under the action of centrifugal force, and then the sealing block 13 is driven to slide into the limiting cylinder 11, so the opening of the sealing seat 10 is no longer blocked, so that the lubricating liquid in the liquid storage tank 8 can flow to the shaft connection, avoiding the damage of the wheel hub and the shaft due to the lack of lubricating liquid for a long time;

[0026] See also Figure 8 A compression spring 16 is fixedly installed between the sealing block 13 and the fixed cylinder 12. The compression spring 16 is sleeved on the outside of the connecting rod 14. The sealing block 13 is made of rubber. The elastic force of the compression spring 16 drives the sealing block 13 to be stuck into the opening of the sealing seat 10, and then the opening is always blocked without external force to prevent leakage of the lubricating fluid.

[0027] When in use, first align the buckle 6 on the wheel hub locking edge 3 with the gap of the locking groove 4 on the wheel hub main side 2, and then move the buckle 6 along the guide groove 5 by rotating, until the wheel hub locking edge 3 is rotated to the bottom of the guide groove 5 and is in a state where it cannot rotate, and then the assembly work is completed. After the tire is inflated, the tire expands, which will force the buckle 6 to be stuck in the limiting groove 7, so that the wheel hub main side 2 and the wheel hub locking edge 3 cannot rotate relative to each other, thereby achieving the effect of preventing loosening;

[0028] When the vehicle is running, the wheel hub will rotate, and the counterweight ball 15 will tend to move outward under the action of centrifugal force, so it will drive the sealing block 13 to slide into the limiting cylinder 11, and the opening of the sealing seat 10 will no longer be blocked, so that the lubricating fluid in the liquid storage tank 8 can flow to the shaft connection.

[0029] In summary, the quick-release wheel hub structure can be assembled by aligning the buckle 6 on the wheel hub locking edge 3 with the gap of the clamping groove 4 on the wheel hub main side 2, and then moving the buckle 6 along the guide groove 5 by a rotating motion until the wheel hub locking edge 3 is rotated to the bottom of the guide groove 5 and cannot rotate. After that, by inflating the tire, the buckle 6 can be clamped into the limiting groove 7 through the expansion of the tire, so that the wheel hub main side 2 and the wheel hub locking edge 3 cannot rotate relative to each other, thereby achieving the effect of preventing loosening, and can be quickly installed and disassembled without using professional tools, thereby improving the user's convenience.

[0030] The quick-release hub structure makes it easier to remove the hub for cleaning and maintenance, thus extending its service life. It also allows for quick replacement of different types of tires according to different riding conditions such as road conditions or weather conditions, thus improving adaptability and flexibility.

[0031] The sealing block 13 is driven by the elastic force of the compression spring 16 to be stuck into the opening of the sealing seat 10, and then the opening is always blocked without external force to prevent leakage of the lubricating fluid. When the wheel hub rotates, the counterweight ball 15 drives the sealing block 13 to slide into the limiting cylinder 11 under the action of centrifugal force, and then the opening of the sealing seat 10 is no longer blocked, so that the lubricating fluid in the liquid storage tank 8 can flow to the shaft connection, thereby avoiding long-term lack of lubricating fluid to damage the wheel hub and the shaft, and extending their service life.
