Abstract

The invention discloses an aircraft tractor. The aircraft tractor comprises a chassis assembly on which a frame is arranged, a cab installed on the frame, a plurality of tractor wheels assembled on the chassis assembly, a front axle and a rear axle, wherein at least some of the plurality of tractor wheels are steerable tractor wheels, an aircraft wheel support assembly and a power assembly are arranged at the middle part of the tractor, and a hydraulic steering assembly is installed at the steerable tractor wheels; the power assembly comprises an engine, the engine, a transmission and a torque converter are arranged in parallel, and the transmission is connected with the front axle and the rear axle of the tractor by drive shafts, and used for the rotation of the tractor wheels during the taxiing of an aircraft; the hydraulic steering assembly comprises a front-axle steering cylinder and a rear-axle steering cylinder, and used for the steering of the tractor wheels during the taxiing of the aircraft. The aircraft tractor disclosed by the invention is provided with the maximum traction force of 12000 kg, the maximum forward running speed of 25 km / h and the maximum reverse speed of 20 km / h.

Description

technical field [0001] The invention relates to vehicle equipment for airport ground, in particular to an aircraft tractor. Background technique [0002] As an important airport ground support vehicle, aircraft tractors are mainly used to tow or push aircraft on airport runways, taxiways and aprons, etc., and play an irreplaceable and important role in both civil and military fields. With the development of the air transport industry, the structure and power system of aircraft tractors continue to develop new technologies and new design ideas, and are applied to aircraft tractors. [0003] Existing aircraft tractors, including the frame and the cab on the frame, drive the tractor through power components, thereby driving the movement of the aircraft. Now, the direction of the tractor is turned purely mechanically. Due to the heavy load of the aircraft, the tractor cannot Effective, fast turning direction, low productivity. Contents of the invention [0004] The technical...
