Description

Technical Field

[0001] This utility model relates to the field of aircraft wheel frame technology, specifically to a small aircraft control wheel bracket. Background Technology

[0002] Small aircraft play an important role in the aviation field. As an important component of the aircraft control system, the control wheel bracket has a crucial impact on the aircraft's handling performance and safety. Currently, most small aircraft control wheel brackets are designed with mechanical structures, using a series of linkages, gears, and bearings to achieve the rotation and positioning of the control wheel.

[0003] Since the control wheel bracket needs to connect to the corresponding wheels, and most wheels are rotatably connected to the bracket, the installation process typically involves using a corresponding axle, with the axle passing through the wheel and bracket for assembly. However, because the wheel is mounted between two plates of the bracket, although there is a rotatable connection between the wheel and the axle, the lack of corresponding limiting and friction-reducing components between the wheel's side and the bracket inevitably results in frictional resistance between the wheel and the side of the bracket, or between the corresponding limiting components. This further increases the resistance during wheel rotation, affecting the wheel's rotation efficiency. Therefore, we propose a control wheel bracket for small aircraft. Utility Model Content

[0004] The purpose of this invention is to provide a small aircraft control wheel bracket to address the deficiencies mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Limiting rings are fixedly installed at the ends of the insertion rings. Multiple annularly spaced grooves are provided on the front and rear sides of the limiting rings. Steel balls are embedded in the grooves. The wheel body is located between the two limiting rings. The axle passes through the insertion rings and the limiting rings. A limiting end is fixedly installed at one end of the axle, abutting against one side plate of the support frame. A stud is fixedly installed at the other end of the axle, and a nut is threaded onto the stud.

[0007] Preferably, the wheel body includes a hub and a tire mounted on the hub, and an axle hole is provided at the center of the hub, through which the axle passes, and the hub and the axle are rotatably connected.

[0008] Preferably, the support frame has perforated holes on both the left and right side plates, and the support frame is fixedly installed on the external frame.

[0029] Please see Figures 1-7 This utility model provides a technical solution: a small aircraft control wheel bracket, including a wheel body 1 and a support frame 2. Bearings 22 are installed in the inner plates of both sides of the support frame 2. A wheel axle 3 extends between the left and right sides of the support frame 2, passing through the wheel body 1. Insertion rings 34 are inserted into the inner rings of both bearings 22, and the insertion rings 34 are rotatably connected to the bearings 22. Limiting rings 33 are fixedly installed at the ends of the insertion rings 34, with two limiting rings 33 located between the two insertion rings 34. The limiting rings 33 are located on the front and rear sides. Each wheel body 1 is provided with multiple ring-shaped, equally spaced recessed grooves 35, and steel balls 351 are embedded in the recessed grooves 35. The wheel body 1 is located between two limiting rings 33. The steel balls 351 abut against the side of the wheel body 1. The steel balls 351 are spherical, and less than half of the sphere of the steel ball 351 is located outside the recessed grooves 35, so that the limiting rings 33 can perform limiting operations on both sides of the wheel body 1 to prevent the wheel body 1 from swaying left and right. In addition, the steel balls 351 can reduce friction, making the wheel body 1 more stable and smooth when rotating.

[0030] Specifically, the axle 3 passes through the insertion ring 34 and the limiting ring 33. One end of the axle 3 is fixedly installed with a limiting end 30 that abuts against one side plate of the support frame 2. The other end of the axle 3 is fixedly installed with a stud 32. A nut 38 is threaded onto the stud 32 to achieve the limiting and fixing operation of the axle 3.

[0031] In this embodiment, the wheel body 1 includes a hub 10 and a tire 11 disposed on the hub 10. An axle hole 12 is provided at the center of the hub 10, and the axle 3 passes through the axle hole 12. The hub 10 and the axle 3 are rotatably connected, so that the wheel body 1 can rotate normally.

[0032] Specifically, the support frame 2 has perforated holes 20 on both the left and right side plates. The support frame 2 is fixedly installed on the external frame, and the perforated holes 20 are used to reduce weight.

[0033] Furthermore, through holes 21 are provided on both the left and right side plates of the support frame 2. Annular grooves 211 are provided on the walls of the through holes 21. The bearing 22 is located in the annular grooves 211, and the wheel axle 3 passes through the through holes 21 for normal assembly operations of the bearing 22.

[0034] In addition, a groove 301 with one end connected to the outside is provided in the limiting end 30. The groove 301 has a hexagonal cross section. The groove 301 is used for limiting operation after a corresponding tool is inserted from the outside, so that the nut 38 can be tightened more smoothly.

[0035] It is worth noting that a baffle plate 31 is fixedly installed on the inner side of the limiting end 30, and the baffle plate 31 abuts against the side plate of the support frame 2; a baffle ring 36 is fitted on the stud 32, and an elastic washer 37 is also fitted on the stud 32. The elastic washer 37 is located on the side away from the wheel axle 3. The nut 38 presses the elastic washer 37 and the baffle ring 36 tightly onto the other side plate of the support frame 2, so as to realize the operation of baffle plate 31 and baffle ring 36 to protect both sides of the support frame 2, and prevent impurities from getting stuck.

[0036] When using the small aircraft control wheel bracket of this utility model, the bearing 22 is placed in the annular groove 211, and the plug ring 34 is inserted into the bearing 22. At this time, the assembly operation of the two limiting rings 33 is realized. Then, the wheel hub 10 is placed between the two limiting rings 33.
