A wheel assembly structure for a fixed-wing aircraft

Abstract

This utility model discloses a wheel assembly structure for a fixed-wing aircraft, including a fairing and rollers. The rollers are located at the bottom end of the fairing and are movably connected to the fairing via axles. A through hole for mounting the rollers is provided at the bottom end of the fairing. Symmetrically arranged rubber-reducing grooves are provided on the wheel surface of the rollers. The rollers are made of POM plastic or PA material. The rollers are made of POM plastic to create a hard wheel, as POM plastic has good wear resistance, resulting in a longer wheel lifespan. The rubber-reducing grooves on the wheel surface reduce the wheel's weight and decrease the contact area between the wheel and the ground roller, correspondingly reducing noise. The axle has a threaded section; during installation, the thread is locked onto the right shell, which has a pre-embedded copper nut. The smooth section of the axle passes through the rollers and fits into a recess in the left shell.

Description

Technical Field

[0001] This utility model relates to the field of fixed-wing aircraft technology, and more specifically, to a wheel assembly structure for a fixed-wing aircraft. Background Technology

[0002] A fixed-wing aircraft is an aircraft with fixed wings that generate lift to support its flight in the air. It typically consists of a fuselage, fixed wings, elevators, rudders, and a power plant.

[0003] When taking off and landing, fixed-wing aircraft inevitably experience strong reaction forces from the ground. Usually, the wheels of fixed-wing aircraft are connected to the fuselage and cannot be disassembled or adjusted, which is labor-intensive and time-consuming.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a wheel assembly structure for fixed-wing aircraft to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A wheel assembly structure for a fixed-wing aircraft includes a fairing and rollers, wherein the rollers are located at the bottom end of the fairing and are movably connected to the fairing via axles;

[0008] The bottom end of the fairing has a through hole for mounting the roller, and the roller has symmetrically arranged rubber-reducing grooves on its surface. The roller is made of POM plastic or PA material.

[0009] Preferably, the fairing consists of a left shell and a right shell, which are joined together to form the fairing.

[0010] Preferably, the left shell has a groove for mounting the axle, and the right shell has a mounting hole for mounting the axle, the mounting hole and the groove being on the same axis.

[0011] Preferably, the axle is threaded at the mounting hole, and a copper nut adapted to the thread is provided in the mounting hole.

[0012] Preferably, the left shell and the right shell are connected by a number of sets of screws.

[0013] Preferably, the roller has several evenly distributed anti-slip grooves on its surface, and the hub of the roller has an eight-spoke structure.

[0014] Preferably, the spokes have a fan-shaped shape.

[0015] The beneficial effects of this utility model are as follows: the roller is made of POM plastic to form a hard wheel, instead of using a plastic wheel hub + pneumatic tire or a plastic wheel hub + EVA foam wheel structure; POM plastic is used because this material has good wear resistance, and the wheel has a relatively long life.

[0016] The roller has a rubber-reducing groove on its surface. This structure reduces the weight of the roller and the contact area between the roller and the ground, which in turn reduces noise.

[0017] There is a thread on the axle. During installation, the thread is locked onto the right shell, which has a pre-embedded copper nut. The smooth section of the axle passes through the roller and is fitted into the groove of the left shell. Attached Figure Description

[0024] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a wheel assembly structure for a fixed-wing aircraft is provided.

[0026] Example 1:

[0027] like Figure 1-3 As shown, the fixed-wing aircraft wheel assembly structure according to an embodiment of the present invention includes a fairing 1 and a roller 2. The roller 2 is located at the bottom end of the fairing 1, and the roller 2 is movably connected to the fairing 1 through a wheel axle 3.

[0028] The bottom end of the fairing 1 is provided with a through hole 4 for mounting the roller 2, and the roller 2 is provided with symmetrically arranged rubber-reducing grooves 5 on the wheel surface. The roller 2 is made of POM plastic or PA material.

[0029] Example 2:

[0030] like Figure 1-3 As shown, the fairing 1 is composed of a left shell 6 and a right shell 7. The left shell 6 and the right shell 7 are spliced ​​together to form the fairing 1. The left shell 6 has a groove 8 for installing the wheel axle 3. The right shell 7 has a mounting hole 9 for installing the wheel axle 3. The mounting hole 9 and the groove 8 are on the same axis. The wheel axle 3 is provided with a thread 10 at the mounting hole 9. A copper nut 11 that is adapted to the thread 10 is provided in the mounting hole 9.

[0031] Example 3:
