Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0022] The invention provides a braking system of a small aircraft, such as figure 1 As shown, the braking system is connected to the hub of the landing gear of a small aircraft. The braking system, such as figure 2 As shown, it includes a pressure gas tank 12, an air pipe 10, an electromagnetic switch 11, a cylinder 13, a piston-pressure plate 7, a driving friction plate 3, a driven friction plate 4, a spline shaft 8 and a bearing 1. The structure of the spline shaft 8 is as follows: Figure 5A and Figure 5B As shown, it is divided into three sections. From left to right, there are polished rod shaft section 801, spline section 802 and end section 803. The outer end surface of the end section has two rectangular protrusions 804 (also called wedges), An annular groove 805 is formed on the inner end surface. The shaft section 801 of the polished...

The invention discloses a small aircraft braking system, which belongs to the technical field of the aircraft braking system. The braking system comprises a pressure air tank, an air pipe, a cylinder, a piston-platen, a driving friction plate, a driven friction plate, a spline shaft and a bearing, wherein the pressure air tank is communicated with the cylinder via the air pipe; the piston-platen is positioned in the cylinder; the driving friction plate and the driven friction plate are both sheathed on the spindle shaft; the driving friction plate is fixedly arranged on a hub via six hexagon socket screws; the driven friction plate is sheathed on the spline shaft via an internal spline; one end of the spline shaft is connected with the hub via the bearing; the other end of the spline shaft is cooperated with the rectangular strut of a wedge block undercarriage to fix the spline shaft onto the undercarriage. According to the small aircraft braking system disclosed by the invention, the small aircraft can stop in a short time within a short distance after landing, and unnecessary damage caused by that the small aircraft runs out of a runway can be avoided. The braking system adopts air of 0.5-0.8MP, and a small pressure air tank is used. The small aircraft braking system has the advantages of simple structure, light weight and convenience in operation.
Description
technical field [0001] The invention relates to a brake system of a small aircraft and belongs to the technical field of aircraft brake systems. Background technique [0002] When manipulating a fixed-wing small aircraft to land, due to the low reliability of the existing braking system, the aircraft will have a long landing distance, or the brakes will lock up, causing unnecessary damage, especially for small aircraft with large wing loads, the landing speed is high, The long sliding distance requires an efficient and reliable braking system to ensure the safety of the flight test. How to design a simple, effective, reliable and long-lived fixed-wing small aircraft brake system has become a technical problem. Contents of the invention [0003] The purpose of this invention is to design a braking system applied to small aircraft, through which the braking system can stop the aircraft in a short time and distance, and the braking braking system has high reliability and dur...
