Problems solved by technology
At present, most aircraft brake control systems are supplied by a set of hydraulic pressure sources, and a brake control valve is installed on each of the left and right wheels, and when the tires are severely worn, high temperature explosions are likely to occur during braking.
In addition, when the aircraft needs to be forced to land, the ground for the forced landing is uneven, and the existing casters of the aircraft are prone to greater wear and tear when sliding on different grounds. Moreover, when an emergency stop is required, the brakes cannot be braked in time, and it still takes a long time. The brakes can stop the plane, which will bring great harm to the scene
In addition, due to the limitation of the casters, the existing aircraft cannot adapt to various uneven grounds or grounds with insufficient hardness. When the road surface is in poor condition and needs to be shut down, there are often great safety hazards

The invention relates to an airplane braking device and belongs to the field of airplane braking. The airplane braking device comprises an airplane body, an undercarriage, an undercarriage braking device, a belly braking device, a first bracket, a first expansion rod, a second bracket, a second expansion rod, braking blocks, a ground, a take-up and landing rod, a tire connecting rod, tires, tire keys, tire key slots, a first parallel expansion rod, a first braking connecting rod, a fixing nut, a second parallel expansion rod, a second braking connecting rod, first braking keys, first braking key slots, second braking keys, second braking key slots, a first vertical expansion rod and a second vertical expansion rod. The tire keys are arranged on two sides of airplane wheels to serve as onepart of the braking device, and severe eccentric wear and high-temperature blast of tires due to direct friction between the braking keys and airplane tires in the braking process can be avoided; secondly, the belly braking device can also play a braking assisting role and guarantee safe braking.
Description
technical field [0001] The invention relates to the field of aircraft braking, in particular to a braking device during aircraft landing and taxiing. Background technique [0002] The aircraft brake control system is an important airborne, whether the brake system can work normally will seriously affect the safety of the aircraft. At present, most aircraft brake control systems are supplied by a set of hydraulic sources, and a brake control valve is installed on each of the left and right wheels, and when the tires are severely worn, high temperature explosions are likely to occur during braking. In addition, when the aircraft needs to be forced to land, the ground for the forced landing is uneven, and the existing aircraft casters are prone to greater wear and tear when sliding on different grounds. Moreover, when an emergency stop is required, the brakes cannot be braked in time, and it still takes a long time. Braking can stop the plane, which will bring great harm to th...
