Brake cooling fan device

Abstract

The invention provides a brake cooling fan device, a brake is used for aircraft wheels of an aircraft landing gear, the brake cooling fan device comprises a mechanical power device and a cooling fan assembly, the cooling fan assembly comprises a fan rotating shaft and a cooling fan fixedly installed on the fan rotating shaft, and the mechanical power device drives the cooling fan assembly to operate. And the cooling fan rotates along with the fan rotating shaft. The mechanical power device comprises airplane wheels and a variable-speed transmission assembly, the variable-speed transmission assembly is connected between the airplane wheels and the cooling fan assembly, the input end of the variable-speed transmission assembly is connected to the airplane wheels in a transmission mode, and the output end of the variable-speed transmission assembly is connected to the cooling fan assembly in a transmission mode. And the rotating power of the airplane wheel is transmitted to the cooling fan assembly through the variable-speed transmission assembly. The output rotating speed of the variable-speed transmission assembly is larger than the input rotating speed of the variable-speed transmission assembly. By means of the brake cooling fan device, an airplane can quickly pass through a station in the operation stage, and the airplane dispatching efficiency can be improved.

Description

technical field [0001] The invention relates to a cooling device used for rapid cooling of wheel brakes of an aircraft during the ground taxiing phase, which is used for the rapid dispatch of the aircraft during the operation phase, and belongs to the field of aircraft airborne brake cooling fan devices. Background technique [0002] With the development of the civil aviation market and the increasing passenger flow, airlines have put forward higher and higher requirements for the efficiency of aircraft transit dispatch, and the wheel brake temperature is an important factor limiting the transit time of aircraft. Improving the cooling efficiency of wheel brakes can greatly shorten the waiting time for the aircraft to cool down on the apron, thereby improving the efficiency of aircraft dispatch. [0003] At present, there are mainly two methods for quick transit of civil aircraft or large transport aircraft: [0004] One method is to install an on-board brake cooling fan dri...

AI Technical Summary

Problems solved by technology

The main disadvantages are: first, the ground auxiliary equipment can be used to cool down only when the aircraft is stable and stationary, and the ground auxiliary equipment cannot be used to cool down during the taxiing phase, and the cooling efficiency is not as good as that of the airborne brake cooling fan; second, it increases the operating cost of the airport , because the airport needs to prepare a large number of air-conditioned vehicles, and the storage, maintenance and dispatch of air-conditioned vehicles will cost a lot of money
