Abstract

The invention discloses a wheel steering device of an aircraft tractor and relates to the technical field of wheel steering devices. The device includes wheels, wherein a connecting rod is fixedly connected to one side of the wheel, one end of the connecting rod is fixedly connected with the rotating block through a brace, one end of the rotating block is movably connected with a threaded rod through a pin shaft, the middle part of the threaded rod is movably connected with a moving block, the outer side of the moving block is provided with a rotating shaft, one end of the rotating shaft is fixedly connected with a first driven wheel, the other end of the rotating shaft is fixedly connected with a second driven wheel, one side of the second driven wheel is movably connected with a drivingwheel, the middle part of the driving wheel is fixedly connected with a main shaft, and one end of the main shaft is fixedly connected with a steering wheel. The threaded rod can fix the connection between the rotating shaft and the threaded rod, the first driven wheel moves the threaded rod through the driving of the steering wheel, so that the wheel can be steered, and a swing rod can drive therear wheels of the aircraft tractor to steer together, thereby reducing the steering time of the aircraft tractor.

Description

technical field [0001] The invention relates to the technical field of wheel steering devices, in particular to a wheel steering device of an aircraft tractor. Background technique [0002] The aircraft tractor is a kind of airport ground equipment that assists the aircraft to reach the designated position on the apron by means of pushing and towing. Due to the high quality of the aircraft, higher requirements are placed on the steering ability of the aircraft tractor. [0003] The steering method of traditional tractors generally adopts a full-hydraulic steering system, which is mainly composed of a hydraulic pump, a full-hydraulic steering gear, a steering cylinder, and a steering bridge. The hydraulic cylinder provides the corresponding steering flow, and then controls the steering speed of the steering bridge wheel, and the steering is realized through the trapezoidal mechanism formed by the steering rod between the steering bridge wheel. [0004] At present, because al...
