Anti-skid and anti-rotation tubeless aviation wheel

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...

AI Technical Summary

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.
