Technical Field

The invention relates to the field of airplane brake devices, in particular to a general airplane brake cooling device.

Background

In order to ensure the safety of taking off and landing of the airplane and shorten the sliding distance, modern airplanes are all provided with disc brakes. During landing rollout, the pilot operates the brakes to slow down the fast moving aircraft and finally to come to a safe and smooth stop. In the short process, the huge kinetic energy of the airplane movement is absorbed by the brake device and converted into heat energy, and the heat energy is consumed in the form of heat. The greater the aircraft load and speed, the heavier the brakes, the more energy the brakes absorb, and the more heat is generated. On the other hand, the more frequently the brakes are used, the more heat is generated by the brakes due to the accumulation of heat. The disc brake has high energy capacity, so the temperature of the brake disc body is high, but the disc brake is arranged in the inner cavity of the airplane wheel due to the limitation of the weight and the overall dimension of the airplane wheel, and the heat dissipation condition is poor. The temperature rise of the airplane wheel mainly comes from brake heat radiation, and the brake heat can not threaten the brake, the airplane wheel and the tire under normal use. However, under heavy load conditions, such as takeoff stopping or continuous braking, the brake heat increases sharply, which leads to serious accidents such as overheating or even fire on the wheels of the brakes. If the wheels overheat or burn excessively, the mechanical properties are severely impaired and may be crushed during operation. Before the aircraft takes off again, the wheel temperature must be reduced to a prescribed safety level, which requires a considerable time under natural cooling, especially in summer, which makes it difficult to meet the increasing rapidity of take-off again and certain special flight requirements, such as continuous take-off braking. The wheel can be cooled by watering, but the water can cause the corrosion and the clamping stagnation of parts, the performance of electrical elements is deteriorated, and for carbon braking, the carbon braking performance is seriously degraded after watering due to the characteristics of the carbon/carbon composite material.

The invention is a general airplane brake cooling device, when in use, two driving motors 5 are synchronously opened in opposite directions to drive a threaded column 7 to rotate, a square column 9 is limited by a limiting sleeve 4 in rotation, the square column 9 is driven to lift through the threaded staggering of the threaded column 7 and the inner wall of a lifting groove 10, the heights of a first cooling box 18 and a second cooling box 30 are adjusted to meet the cooling requirements of brake discs with different heights, a supporting plate 8 is arranged to support the rotation of the threaded column 7, a limiting block 11 is arranged to prevent the square column 9 from separating from a supporting column 3, a hydraulic push rod 21 pushes the first cooling box 18 to move left, so that the first cooling box 18 and the second cooling box 30 are closed, the brake discs are wrapped between the first cooling box 18 and the second cooling box 30, grooves matched with a brake disc connecting shaft are formed on the wall body at the center of the front side and the back side of the second cooling box 30, the connection between the connecting ring 19 and the guide groove 29 is tightly sealed, air in the first cooling box 18 and the second cooling box 30 is extracted at high pressure through the first air delivery pipe 15, the second air delivery pipe 16 and the third air delivery pipe 17 by the exhaust fan 12, air in the first cooling box 18 and the second cooling box 30 is sucked through the air inlet hole 32 to complete high-speed circulation of air flow, the effect of efficiently cooling the brake disc is achieved, meanwhile, dust is prevented from entering between the first cooling box 18 and the second cooling box 30 to cause abrasion to the brake disc, the guide is provided for the movement of the first cooling box 18 through the matching work of the arranged supporting sleeve 20 and the limiting rod 34, the connecting rod 26 is pulled to move out of the bearing platform 22 when the first cooling box 18 moves, the anti-bending capability of the connecting rod 26 is enhanced while the connecting rod 26 moves stably through the movement of the arranged guide rod 25 in the guide groove 29, and the arranged friction reducing ring 23, for the removal of connecting rod 26 provides the direction, through the ball 27 that sets up in the inside removal of spout 24, make connecting rod 26 remove the steady while reinforcing connecting rod 26 resist the bending ability, ball 27, antifriction ring 23, the guide arm 25 through setting up form the diversified support of multiple spot, make cushion cap 22, connecting rod 26's extending structure have the bearing effect, accept the gravity of first cooling box 18, for the removal of first cooling box 18 provides the direction, avoid hydraulic push rod 21 to receive vertical force to damage.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
