JPH07149295A - Aircraft landing time tire same speed rotating method and device therefor - Google Patents

Abstract

PURPOSE:To quickly achieve a stable condition, enable safe landing, and reduce damage of the tire by rotating the tire at the same speed as that of an aircraft when the aircraft lands by using a motor or the like, and landing the aircraft. CONSTITUTION:At landing time, first of all, a motor gear 15 of a motor 25 rotates, and an idle rotation wheel 6 rotates, and when an idle rotation rib rotates, since the tip turns toward the center by centrifugal force, it meshes with a hook gear 3, and a tire wheel 23 and a tire 2 rotate together with a hook gear projection 27 of the hook gear 3. For example, at landing time, when speed of an aircraft becomes faster than that by rotation of the motor 25, the hook gear 3 idly rotates around the idle rotation wheel 6. When it becomes slow, a wheel shaft 1 is raised, and when a pushing-down rod receiver 20 is raised, a pushing-down rod strikes against the pushing-down rod receiver 20, and the pushing-down rod receiver 20 is rotated, and pushes out a slide rod 9. Thereby, the idle rotation rib 4 and the hook gear 3 idly rotate.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for protecting tires when an aircraft lands.

[0002]

2. Description of the Related Art An aircraft will land on the ground at a fairly high speed even when landing. In that case, in the conventional technique, the tire is not rotating at all. Therefore, at the time of landing, the tire suddenly contacts the ground, so the shock due to the speed difference caused the tire to be considerably damaged, and in some cases the tire bursts, causing a serious accident involving human life, You are in danger.

[0003]

[Problems to be Solved by the Invention] Whether or not an aircraft can land safely is extremely important for human life. It is a major issue to prevent accidents such as tire bursts and accidents such as tire bursts and sticking out of the ice burn runway after the aircraft has landed due to the above-mentioned tire damage and related shocks on landing. .

[0004]

As a measure for safety, when the aircraft lands, the tire (2) is rotated at the same speed as the aircraft by a motor (25) or the like to land.

[0005]

The function of rotating the tire (2) by the motor (25), wind force or power of the aircraft when the aircraft is landing is the same because the speed of the aircraft and the speed of rotation of the tire (2) are the same. The landing will be smooth and the shock due to friction during landing will be greatly reduced, and the tire (2) will not be damaged. As a result, the aircraft is extremely safe to land.

[Example] Description of tire rotation by a power transmission device of a motor

[Fig. 2]

[Figure 3]

[Figure 7]

[Fig. 8] As shown in Fig. 8, when landing, first the motor (25)
The power is transmitted to the motor rotating shaft (14) by rotating the motor, and the motor gear (15) rotates. Thereby

[Fig. 2]

[Figure 4]

As shown in FIG. 7, the idle wheel (6) rotates as shown by the arrow, and the idle rib (4) rotatably mounted on the stop shaft (5) rotates about the axle (1), causing centrifugal force. Since the tip of the hook moves toward the center due to the force, it engages with the hooking gear (3), and the hooking gear (3) rotates.

As shown in FIG. 7, all of the hooking gear projections (27) rotate around the axle (1), and the hooking gear projections (2) are rotated.
7) and

[Fig. 2]

As shown in FIG. 8, the tire wheel (23) and the tire (2) rotate in the direction of the arrow. And the long arrow shows the course of the aircraft.

Description of motor power disconnecting device 1 When the speed of rotation of the tire (2) is faster than that of the motor (25),

[Figure 4]

As shown in FIG. 7, the hooking gear (3) rotates only in one direction due to the idling rib (4). For example, the speed of the aircraft during landing is faster than the speed due to the rotation of the motor (25). In this case, the gear (3) spins around the idle wheel (6) and spins around the idle wheel (6), thereby eliminating the load on the mechanism due to the excessive rotational force from the tire (2).

Motor power disconnection device explanation 2 On the contrary, when the speed of the aircraft becomes slower than the speed due to the rotation of the motor (25) at the time of landing,

[Figure 1]

As shown in FIG. 2, when the tire (2) is lifted at landing, all parts attached to the spring (10) are lifted up. Therefore axle (1) axle stop (17)
The lifted down lot holder (20) attached to the lifting stop shaft (19) lifts. At that time, the depressed lot (12) hits the depressed lot receiver (20). As a result, the push-down lot (12) pushes down the push-down lot receiver (20), and the push-down lot receiver (20) is pushed around the stop shaft (19) in the unmarked direction, and the slide lot ( Push out 9) in the direction of the arrow.

[Fig. 2]

[Figure 4]

As shown in FIG. 7, the slide lot (9) hits the outside of the rotating idle rib (4), and the idle rib (4) and the hooking gear (3) idle. This too

Similarly to the above, the load on this mechanism due to the rotational force from the tire (2) is eliminated.

Description of multiple parallel tire transmission power

When a parallel tire is formed as shown in FIG. 11, power is transmitted from the inner tire (2) rotated by the power of the motor (25) to the outer tire (2) and rotated.
Attach the rotating body receiving slide tube (33) to the inner wheel with bolts

FIG. 9

[Fig. 11] As shown in Fig. 11, the rotor (29) is attached to the tip of the tire and the rotor soft blades (32) around the rotor are applied to the tire wheel protrusions (30) and slowly rotated, so that the outer tire (2) is powered. Go around. Also, if any of the tires (2) receives a large external force and the speeds due to the rotations are different, the rotor soft blades (32) are made of an elastic material, so that the force is not less than a certain force. When hitting the tire wheel protrusion (30), the tip of the rotor soft blade (32) bends and the rotor soft blade (32)
Slips on the tire wheel protrusions (30), and the tires (2) rotate by independent rotation.

[0010]

EFFECTS OF THE INVENTION Aircraft accidents are extremely catastrophic and cheap, especially when taking off or landing. Above all, landing in bad weather is extremely bad, and conditions such as snowstorms and ice burns are the worst, and slipping can cause the landing to run off the runway, so smoother landing is required. With the invention of wood, when landing, you can land smoothly, and you can enter a stable state faster, so you can decelerate quickly and land extremely safely. In addition, the tire (2) has very few damages, which is also safer and enables economical operation.
