Problems solved by technology

For example, due to the high thrust of the aircraft, the braking torque of the take-off line is high, and the sliding of tires and movable rims is easy to occur.
The result of the tire sliding or rotating relative to the wheel is that the car cannot be braked directly, causing the aircraft to roll forward, affecting normal use, and even causing accidents, which poses a great safety hazard; and the sliding of the movable rim on the hub of the wheel will cause Rapid wear of the movable rim and wheel hub parts reduces wheel life
It is an urgent need for the normal use of tubeless aircraft wheels and the continuous development of aircraft power to solve the problem of possible wheel parts slipping or sliding rotation in the prior art.

Embodiment 1

[0027] An anti-slip tubeless aircraft wheel, the anti-slip can prevent the wheel tire from sliding relative to the wheel and prevent the movable rim from sliding relative to the wheel hub.

[0028] The anti-slip tubeless aircraft wheel includes an aircraft wheel and a tubeless tire. Machine wheel is made up of machine wheel hub 1 and movable rim 4. The large end of the wheel hub 1 has a radially protruding fixed rim 3, and the small end of the wheel hub is equipped with a movable rim 4, and the movable rim 4 is installed in the outer circular snap ring groove of the small end of the wheel hub. The inner snap ring 5 is fixed. The airtightness of movable rim 4 and the mating surface of machine wheel hub 1 is guaranteed by the sealing ring 7 installed in the outer annular groove of the small end of the machine wheel hub.

[0029] The tread 10 of the tubeless tire 2 includes a fixed rim tread and a movable rim tread. Wherein: the mating surface of the fixed wheel rim and the wh...

Embodiment 2

[0046] The present embodiment is an anti-slip tubeless aircraft wheel, including a wheel and a tubeless tire. The wheel includes a wheel hub 1 and a movable rim 4 .

[0047] The large end of the wheel hub 1 has a fixed rim 3 protruding radially; Ring 5 is fixed, and the airtightness of movable wheel rim 4 and machine wheel hub 1 mating surface is guaranteed by the sealing ring 7 that is installed in the outer annular groove of machine wheel hub small end.

[0048] The tread 10 of the tubeless tire 2 includes a fixed rim tread and a movable rim tread. Wherein: the mating surface of the fixed wheel rim and the wheel hub 1 is divided into three parts: the first part is the mating surface of the wheel hub profile, and the length of the mating surface of the wheel hub profile is Lb g . The second part is the arc area R at the root of the fixed rim g , the arc area R at the root of the fixed rim g The arc length is LR g . The third part is the mating surface of the fixed rim ...

Embodiment 3

[0058] The difference between this embodiment and Embodiments 1 and 2 is that the surface where the tubeless tire cooperates with the fixed rim and the movable rim of the wheel hub does not have the ribs.

[0059] The present embodiment comprises machine wheel and tubeless tire; Machine wheel is made up of machine wheel hub 1 and movable rim 4. The large end of the wheel hub 1 has a radially protruding fixed rim 3, and the small end of the wheel hub is equipped with a movable rim 4, and the movable rim 4 is installed in the outer circular snap ring groove of the small end of the wheel hub. The inner snap ring 5 is fixed. The airtightness of movable rim 4 and the mating surface of machine wheel hub 1 is guaranteed by the sealing ring 7 installed in the outer annular groove of the small end of the machine wheel hub.

[0060] The mating surface between the fixed rim 3 of the wheel hub and the tubeless tire 2 is divided into three parts: the first part is the mating surface of th...

Abstract

The invention provides an anti-skid and anti-rotation tubeless aviation wheel. A tire foot of a fixed rim of a tubeless tire comprises a wheel hub profile matching face and a fixed rim surface matching face, and a tire foot of a movable rim comprises a movable rim profile matching face and a movable rim surface matching face or smooth faces, or a plurality of anti-slip grooves are formed in the fixed rim and the movable rim. A plurality of annular anti-slip grooves are formed in the surface, matched with the tire foot of the tubeless tire, of the fixed rim of the wheel and the surface, matchedwith the tire foot of the tubeless tire, of the movable rim of the wheel. Two or three stop keys or stop pins are arranged between the matched surfaces of a wheel hub and the movable rim. According to the anti-skid and anti-rotation tubeless aviation wheel, the retention force at the junction of the tire and the wheel is improved through the anti-slip grooves, and sliding and rotation of the movable rim are prevented through the stop keys or the stop pins; and the anti-skid and anti-rotation tubeless aviation wheel is reasonable in structural design, easy and convenient to use, and feasible;and the problem that the tubeless tire can slide and rotate relative to the wheel under a large torque condition is effectively solved, and normal usage of the tubeless aviation wheel is ensured.

Description

technical field [0001] The invention relates to an aircraft wheel, in particular to a tubeless aircraft wheel which prevents a tire from sliding relative to the wheel and a movable rim from sliding relative to the hub of the aircraft. Background technique [0002] Aerospace wheels include tubeless and tubeless aviation wheels. Aerospace wheels with inner tubes were used in early aircraft. Tubeless aircraft wheels have the characteristics of light weight, convenient use and maintenance, etc., and are widely used in modern aircraft. The tubeless aircraft wheel includes a machine wheel and a tubeless tire, and the wheel structure has a movable rim type and a split structure. The bonding surface between the rim of the machine wheel hub and the tire is smooth without knurling, the tire is installed between the two rims of the wheel hub, and the inside of the tire tire and the outer surface of the wheel hub form a closed annular cavity. After the tire is inflated, the inflation...
