Traction system used for traction of aircraft

Abstract

The invention discloses a traction system used for traction of an aircraft. The traction system comprises a rod body, a traction ring, a hydraulic control system, a traveling mechanism, a front connecting rod I, a front connecting rod II, a rocker arm I, a rear connecting rod I, a rocker arm II, a rear connecting rod II, a pulley and steel wire rope assembly, an auxiliary wheel I and an auxiliary wheel II, wherein the traction ring is arranged at the front end of the rod body and used for being connected with a traction car; the hydraulic control system is used for controlling the rod body to ascend and descend; the traveling mechanism is located in the middle of the rod body and arranged under the rod body; the front connecting rod I and the front connecting rod II are located on the two sides of the rod body correspondingly; the rocker arm I and the rear connecting rod I are matched with the front connecting rod I; the rocker arm II and the rear connecting rod II are matched with the front connecting rod II; the pulley and steel wire rope assembly is arranged on the rear middle portion of the rod body; the auxiliary wheel I is arranged on the front connecting rod I; and the auxiliary wheel II is arranged on the front connecting rod II. The function that the aircraft can control steering in the traction process is achieved through the traction system, and meanwhile the traction system is simple in structure, low in manufacturing cost, good in buffer performance, convenient to mount, dismount and convey and capable of being widely applied and popularized.

Description

technical field [0001] The invention belongs to the field of aviation ground equipment, and in particular relates to a towing system for towing an aircraft. Background technique [0002] Towing equipment is the equipment used to move the aircraft before take-off and after stopping, including tow bar, hand tow bar, and tow wire. Generally, normal traction in my country uses a tractor to tow the aircraft through the towbar, and the towing speed is 5-20km / h. At present, my country's aircraft traction forms can be divided into two types, one is single-point traction, the traction connection point is on the nose landing gear, and the connection between the traction bar and the nose landing gear is a rigid connection; the other is three-point traction or three-point traction The above towing forms have towing points on both the nose landing gear and the main landing gear, and are connected to the main landing gear in a flexible connection. [0003] At present, most of the researc...
