Aircraft tractor and traction mechanism used thereon

Abstract

The invention relates to an aircraft tractor and a traction mechanism used thereon. The traction mechanism comprises a traction bolt component, a frame connecting piece, and a rear axle connecting piece, wherein the frame connecting piece comprises a crossbeam, and a vertical plate fixedly connected with a frame of the aircraft tractor and connected with the crossbeam; the rear axle connecting piece comprises a direct connecting piece and a connecting rod; one end of the direct connecting piece is fixedly connected with a rear axle of the aircraft tractor, and the other end of the direct connecting piece is hinged with the connecting rod; the traction bolt component comprises a traction bolt body, an upper part connecting body connected with the upper part of the traction bolt body, and a lower part connecting body connected with the lower part of the traction bolt body; the upper part connecting body is hinged to the crossbeam; the lower part connecting body is hinged to one end of the connecting rod far from the direct connecting piece. The traction mechanism can reduce the stress of the aircraft tractor and reduce the additional force generated because the direction of the tractive force is inconsistent with the direction of motion in the traction process.

Description

technical field [0001] The invention relates to an aircraft tractor, in particular to a traction mechanism used on the aircraft tractor. Background technique [0002] Aircraft tractors are working vehicles used to tow or push aircraft. They are an indispensable ground support equipment for modern airports. Using aircraft tractors to move aircraft can save aircraft fuel, reduce noise and exhaust pollution, and reduce aircraft engine damage. wear and tear. According to the different ways of towing the aircraft, it is divided into two types: rod towing and rodless towing. The two ends of the towing rod are connected to the aircraft tractor and the aircraft respectively. The tractor tows the aircraft through the tow bar. Independent of aircraft and aircraft tugs. [0003] The towing pin is a mechanism connected to the aircraft towing bar on the aircraft tractor, such as figure 1 As shown, the towing bolt 20 is usually found in the front and rear of the aircraft tractor, and i...

Problems solved by technology

[0003] The towing pin is a mechanism connected to the aircraft towing bar on the aircraft tractor, such as figure 1 As shown, the towing bolt 20 is usually found in the front and rear of the aircraft tractor, and it is directly installed or welded on the car body 10 of the aircraft tractor. The force point is single, which increases the force on the aircraft tractor; at the same time, the traction bolt of this structure makes the positions of the tow bar and the aircraft tractor relatively fixed, and additional force will be generated when the direction of the traction force is inconsistent with the direction of motion during the traction process
