Embodiment Construction

[0034] The present invention will be further introduced below in conjunction with the accompanying drawings and specific implementation, but not as a limitation of the present invention.

[0035] The aircraft main wheel of the present invention is composed of a wheel assembly and a brake device, which is installed on the main landing gear shaft of the aircraft, and the brake device is located in the first chamber 101 of the wheel assembly. The landing gear shaft rolls.

[0036] Such as figure 1 and figure 2 As shown, the wheel assembly includes: hub 1, rim 2, half snap ring 3, sealing ring 4, end cover assembly 5, oil deflector ring 6, tapered roller bearing 7, adjusting bushing 8, valve assembly 9, Thermal melt plug 10, guide rail 11, heat shield 12.

[0037] The hub 1 is made of a high-strength aluminum alloy forging and is a single-web structure. There are 9 bosses (not shown in the figure) evenly distributed on the inner wall, and 9 guide rails 11 are correspondingly i...

Abstract

The invention belongs to an aircraft take-off and landing system, in particular to an aircraft main wheel. The main engine wheel of the aircraft includes a wheel assembly and a brake device, and the wheel assembly includes a hub, a wheel rim, a half snap ring, a guide rail, a tapered roller bearing, an adjusting bush, an oil deflector ring, a heat shield, and a valve assembly and thermal fuse plugs; the brake device includes a cylinder block assembly, a piston assembly, a brake housing, a brake disc and a heat shield. The wheel hub is a single web structure, which is convenient for tire disassembly and provides a large cavity that can accommodate the brake device; the wheel hub is made of aluminum alloy, which has the advantages of large bearing capacity and long service life; the brake shell The body has the advantages of light weight, high strength, high temperature resistance, simple structure, convenient use and maintenance; the brake device adopts two sets of hydraulic brake and pneumatic brake pistons that act independently, so that when any component fails or loses any brake energy Down, still able to stop the aircraft.

Description

technical field [0001] The invention belongs to an aircraft take-off and landing system, in particular to an aircraft main wheel. Background technique [0002] The main wheel of the aircraft is installed on the main landing gear of the aircraft, and is used for parking, taxiing, landing and energy absorption of the aircraft on the ground. [0003] The main wheel of the aircraft includes the wheel assembly and the brake device, which are used together with the supporting tires for the aircraft to take off, land, taxi, brake and park on the ground. [0004] The wheel assembly is composed of a hub, rim, guide rail, bearing, etc.; the brake device is composed of a cylinder block assembly, a piston assembly, a brake housing, and a brake disc. [0005] The utility model authorization announcement number is CN 201971153 U providing a front wheel of an aircraft, including the left front wheel and the right front wheel, both of which are center split structures, including inner half...
