Problems solved by technology

[0002] The landing speed of the aircraft is generally 200km / h, and the aircraft tires remain stationary before landing, so the aircraft tires will have severe friction with the ground at the moment of landing, causing the temperature inside the tire to rise sharply, and the hysteresis loss of the rubber compound will increase. The tires are prone to frictional damage such as tread throwing and block falling, and even tire blowouts and other accidents that endanger the safety of passengers

Abstract

The invention relates to an aircraft tyre driver with an energy recovery function. Because an aircraft lands and is braked, kinetic energy of a tyre is consumed by the friction between a dynamic brake disk and a static brake disk, a large amount of energy is wasted. The aircraft tyre driver mainly comprises a fixing ring, a rectifier, a storage battery, a rectifying line, a charging line, a motor and a friction wheel, wherein the storage battery supplies power to the motor when the aircraft lands so as to drive the friction wheel to drive the tyre to rotate, and thus the speed difference between the tyre and the ground is reduced, and the abrasion loss of the tyre is reduced. The aircraft tyre drives the friction wheel to rotate during speed reducing and rotating on a runway, the friction wheel drives the motor to charge the storage battery, and therefore, the kinetic energy during the braking can be reasonably and fully recycled, the abrasion between a dynamic disk and a static disk in an aircraft wheel brake device is reduced, the time required from the braking to the stopping of the tyre is shortened, and the charging and the power supplying of the storage battery can be finished in a circulating process.

Description

technical field [0001] The invention relates to an aircraft tire driver with energy recovery function, which belongs to the field of aircraft tire drive design. Background technique [0002] The landing speed of the aircraft is generally 200km / h, and the aircraft tires remain static before landing, so the aircraft tires will have severe friction with the ground at the moment of landing, causing the temperature inside the tire to rise sharply, and the hysteresis loss of the rubber compound will increase. The tires are prone to friction damage such as tread throwing and block falling, and even accidents such as tire blowouts that endanger the safety of passengers may occur in severe cases. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned problems that exist when aircraft tires land, and to design an aircraft tire driver with an energy recovery system, which can also recover a part of the braking energy of aircraft tir...
