Description

Technical Field

[0001] This utility model relates to the field of wheel technology, and in particular to a detachable wheel. Background Technology

[0002] It is very convenient for daily tire wear and replacement, seasonal tire replacement (such as summer tires and winter tires), and sudden tire damage (such as tire blowout), saving time and effort. Or, it can easily change rims under various usage conditions to adapt to different driving conditions.

[0003] In motorsports, tires can be quickly changed to suit different track conditions and race strategies to achieve optimal performance. Conversely, if a wheel rim is damaged, the entire tire must be repaired and replaced, increasing repair and replacement costs and hindering emergency vehicle support. Furthermore, undamaged parts of the wheel become unusable, resulting in significant resource waste. Even when some parts are replaceable, tire inflation may fail, rendering the tire unusable. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a detachable wheel that enables the hub to be detached and replaced efficiently through detachable components.

[0005] The technical problem to be solved by this utility model is achieved through the following technical solution: a detachable wheel, including a tire, an inner rim with a wheel sleeve, and a sealed arrangement between the tire and the outer rim of the wheel sleeve to form an inflation chamber. The inner rim of the wheel sleeve has countersunk mounting holes evenly distributed circumferentially. A detachable hub is provided inside the wheel sleeve, including an outer rim that mates with the inner rim of the wheel sleeve. A hub core is provided inside the outer rim. Several spokes radiate outwards from the outer rim and hub core, and a detachable component mates with the countersunk mounting holes between two adjacent spokes. The radial outward distribution of the spokes reduces the tire's weight while enhancing the stability of the hub.

[0006] The independent inflation chamber prevents air leakage during the removal of the wheel rim from the hub. The hub is removable via a detachable component, so when parts such as the outer rim, hub core, or spokes are damaged, the entire wheel does not need to be replaced; only the damaged hub portion needs to be removed and replaced. This convenient disassembly significantly reduces repair costs and time.

[0007] As a further embodiment of this utility model, a thick ring is formed between the outer ring and the inner ring of the wheel sleeve. The countersunk mounting hole is set along the circumferential radius of the thick ring. The depth of the countersunk mounting hole is less than the thickness of the thick ring. The countersunk mounting hole is provided with an internal thread. The upper and lower edges of the outer ring of the wheel sleeve are provided with wheel sleeve grooves for installing tires.

[0008] The thick ring structure gives the wheel sleeve sufficient strength in both the radial and circumferential directions, enabling it to better withstand the radial, tangential, and lateral forces generated by the tire during driving, thereby improving the overall stability and reliability of the wheel and reducing deformation or damage caused by insufficient wheel sleeve strength.

[0009] The countersunk mounting holes are set along the circumferential radius of the thick ring body, and the hole depth is less than the thickness of the thick ring body. This allows for a more reliable connection between the detachable components and the wheel sleeve, while effectively ensuring a constant inflation pressure in the inflation chamber and preventing air leakage and pressure drop due to stress.

[0010] As a further embodiment of this invention, the outer ring of the wheel hub and the inner ring of the wheel sleeve have an overfitting fit. The outer ring of the wheel hub is provided with a mounting through hole corresponding to the countersunk mounting hole, and the inner diameter of the mounting through hole is larger than the inner diameter of the countersunk mounting hole. This increases the contact area between the outer ring of the wheel hub and the inner ring of the wheel sleeve, improving the friction and connection strength between them. This enhances the wheel's impact resistance and fatigue resistance. The larger inner diameter of the mounting through hole allows for more accurate alignment of the detachable component with the countersunk mounting hole during installation, facilitating installation.

[0011] As a further embodiment of this invention, the detachable component includes a positioning sleeve disposed in a mounting through hole. A pre-pressurized threaded insert, which mates with a countersunk mounting hole, passes through the positioning sleeve. The pre-pressurized threaded insert includes a mounting stud, with a tightening nut and a locking nut at its free end. The positioning sleeve is locked in the mounting through hole by the tightening nut along the length of the mounting stud. The mating of the pre-pressurized threaded insert with the countersunk mounting hole, along with the dual locking mechanism of the tightening nut and the locking nut, enhances the connection strength of the detachable component. The dual locking mechanism of the tightening nut and the locking nut effectively prevents dangerous situations such as wheel hub detachment due to nut loosening.

[0012] As a further embodiment of this invention, the screw nut and locking nut are fitted with protective caps, the hexagons of which are inscribed within the inner circle of the protective caps. The protective caps effectively prevent the screw nut and locking nut from being exposed to the external environment, avoiding rust and corrosion caused by environmental factors such as rain, dust, and salt spray.

[0013] As a further embodiment of this invention, the wheel hub core includes a circular core body with a central hole at its center for mating with the wheel axle. The central hole allows the wheel hub core to be easily mounted on the wheel axle.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a detachable wheel, including a tire, an inner rim of the tire with a wheel sleeve, the tire and the outer rim of the wheel sleeve are sealed together to form an inflation chamber, the inner rim of the wheel sleeve has countersunk mounting holes evenly distributed around its circumference, the wheel sleeve has a detachable hub, the detachable hub includes a hub outer rim that mates with the inner rim of the wheel sleeve, the hub outer rim has a hub core, and a number of spokes radiate outwards from the outer rim and the hub core, and a detachable component that mates with the countersunk mounting holes is provided between two adjacent spokes.

[0015] (1) The independent inflation chamber prevents air leakage during the disassembly of the wheel rim and hub. The hub is detachable through a detachable component. When the outer rim, hub core, or spokes are damaged, it is not necessary to replace the entire wheel; only the damaged hub part needs to be removed and replaced. Disassembly is convenient, greatly reducing maintenance costs and time. The spokes radiate outwards from the center, reducing tire weight and enhancing hub stability.

[0016] (2) A thick ring is formed between the outer ring and the inner ring of the wheel sleeve. The thick ring gives the wheel sleeve sufficient strength in both the radial and circumferential directions, enabling it to better withstand the forces generated by the tire during driving, improve the overall stability and reliability of the wheel, and reduce deformation or damage caused by insufficient wheel sleeve strength.

[0017] The depth of the countersunk mounting hole is less than the thickness of the thick ring, allowing for a more reliable connection between the detachable components and the wheel sleeve. At the same time, it effectively ensures a constant inflation pressure in the inflation chamber, preventing air leakage and pressure drop due to stress.

[0018] (3) The outer ring of the wheel hub and the inner ring of the wheel sleeve are fitted together. The outer ring of the wheel hub is provided with a mounting through hole corresponding to the countersunk mounting hole. The inner diameter of the mounting through hole is larger than the inner diameter of the countersunk mounting hole. The contact area between the outer ring of the wheel hub and the inner ring of the wheel sleeve is increased, which improves the friction and connection strength between the two. This enhances the impact resistance and fatigue resistance of the wheel.

[0019] (4) The fit between the pre-pressurized threaded insert and the countersunk mounting hole, as well as the dual locking mechanism of the screw nut and the lock nut, together enhance the connection strength of the detachable component. The dual locking mechanism of the screw nut and the lock nut effectively prevents dangerous situations such as wheel hub detachment caused by loose nuts. Attached Figure Description
