Problems solved by technology

Since the tire loses its friction function due to wear and tear, the load-bearing and driving functions cannot continue to be used, and it is difficult to achieve an equal-life design, resulting in a lot of waste

Embodiment Construction

[0021] The present invention realizes like this to the braking of aircraft: brake shoe 3 is connected on the brake bar 2, has certain degree of freedom. The brake lever 2 is installed at the rear of the aircraft and is located in the wheel plane, and the brake lever 2 is connected with the power source of the aircraft braking system.

[0022] When the aircraft needs to be braked after landing, the driver activates the operating system to lower the brake lever 2 to contact the ground at the X-axis 1 to apply pressure. Simultaneously step on the clutch to make the wheels in a driven rolling state. The descending height of the brake lever 2 is controlled by the load-sensing pressure-limiting valve, so that the brake shoe 3 exerts an appropriate pressure on the ground when the aircraft has different loads, so as to keep the aircraft balanced.

Abstract

The invention relates to an airplane braking field, when braking, the brake feet falls on the X-axis on the ground and rubs against the ground, so as to generate ground braking force, and eliminating deflection moment, thus eliminating the phenomena of deviating, sdieslipping and tailing. The wheels are in a driven state, keeping guiding and making the airplane have good directional stability. The descending height of the brake feet is controlled by load sensing pressure limiting valve to keep balancing the airplane. It radically eliminates the deflection moment caused by unequal two-side braking forces. In addition, the wheels is in a driven rolling state and still has guiding force and adhesive force, to make the airplane have good directional stability, able to prevent sideslipping and tailing, enhancing braking efficacy of the airplane, shortening braking distance and reducing tyre wear. It can also enhance thermal decay resistance, simplifies original braking system and has extremely high social and economic benefits.

Description

technical field [0001] The invention relates to the field of aircraft braking. Background technique [0002] Existing aircraft utilizes the sliding friction between the wheels and the ground to generate ground braking force to achieve the purpose of braking. The wheels are located on both sides of the aircraft, that is, their braking points are located on both sides of the X-axis of the aircraft (the intersection line between the wheel plane—the middivision plane of the wheel perpendicular to the rotation axis of the wheel—and the ground). There is a certain distance between the two braking points, that is, the wheelbase. The inconsistency of the braking force of the brakes on both sides of the aircraft and the inconsistency of the roughness of the road surface on both sides make the ground braking force on both sides of the aircraft unequal. [0003] When the aircraft brakes, a pair of inertial force and braking resistance in opposite directions are generated. The braking...
