Description
Technical field
It is specifically a kind of to prevent tire from sliding and preventing movable wheel rim with respect to machine with respect to wheel the present invention relates to Inspection Aircraft Wheels
Take turns the tubeless Inspection Aircraft Wheels of wheel hub sliding.
Background technique
Inspection Aircraft Wheels include the inner tube of a tyre and tubeless Inspection Aircraft Wheels.There are inner tube of a tyre Inspection Aircraft Wheels for early stage aircraft.Without in
Tire Inspection Aircraft Wheels have the characteristics that light-weight, working service is convenient, are used widely on modern aircraft.Tubeless aviation machine
Wheel includes wheel and tubeless tyre, and wheel structure has activity flange style and opposite opened structure.Wheel hub wheel rim and tire paste
Conjunction face is smooth, and without annular knurl, tire is mounted between two wheel rim of wheel hub, and in tire and wheel hub outer surface surrounds envelope
Closed-loop shaped inner cavity.After tyre inflating, tire foot is included that sidewall is extruded on wheel wheel rim by the blowing pressure in tire, is being taken turns
Tire and wheel contact surface form binding force, use fixing tire.With the swift and violent raising of aircraft power, tubeless Inspection Aircraft Wheels wheel
Tire fixing power exposes deficiency, potential danger of the prior art there are tire with respect to wheel sliding.In addition, for using castor
The wheel of edge structure, movable wheel rim do not have stop device circumferentially in wheel hub, and therefore, it is opposite that the prior art has movable wheel rim
The potential danger of wheel hub sliding.Tire and movable wheel rim slide relative to wheel hub or rotate this problem in certain condition
Under (such as inflation pressure of tire is low, and brake torque is big) will appear.For example, take-off line brakes since aircraft thrust is very big, thus stop
Vehicle torque giant tyre and movable creep are easy to happen.Tire relative to wheel slide or rotate as a result, it is direct performance be stop
Incessantly vehicle leads to aircraft rolls forward, influences normal use, or even the sign that causes the accident, security risk are big；And movable wheel rim exists
It is slided on wheel hub, will lead to movable wheel rim and wheel hub part Fast Wearing, shorten wheel service life.It solves existing
May occur present in technology wheel part trackslip i.e. sliding rotational problems be tubeless Inspection Aircraft Wheels normal use and aircraft
Power continue to develop there is an urgent need to.
