The good draw bar of interchangeability in favor of improving production efficiency, while can reduce the quantity of draw bar, and saving producing cost is all
Very advantageously, it is therefore necessary to design the draw bar shared to each model aircraft.
Invention content
The purpose of this utility model is to provide a kind of plane draw bars, and the bayonet being equipped with by kelly is to different aircrafts
Wheel carries out towing pad, solves the problems, such as that also difference needs be furnished with dedicated draw bar for towing pad size and liftoff height, and
The machine for being suitble to Multiple Type winged can reduce the quantity of draw bar in favor of improving production efficiency, save producing cost all
It is very favorable.
In order to solve the above technical problems, the utility model is achieved through the following technical solutions：
The utility model is a kind of plane draw bar, including tailstock and pull rod, and the tailstock is a "U" shaped steel member；
It is mounted on first tire on one opposite flank of the tailstock；One outer bottom of the tailstock is equipped with the first free bearing；It is described
One end of pull rod is equipped with connector, and the other end is equipped with draw ring；The pull rod is equipped with wheel close to the both sides of connector one end
Frame；Second tire is installed on the wheel carrier；It is hinged by the first free bearing and connector between the tailstock and pull rod；The tail
Two cross bars are equipped in the U-typed frame of frame, wherein a cross bar is equipped with two second free bearings；The one of second free bearing and kelly
End is hinged.
Further, it is connected by a rotating disc between the pull rod and draw ring；The draw ring radially 360 ° of rotations.
Further, the 180 ° of rotations of axis pin of the pull rod along the first free bearing.
Further, the kelly is gone into battle, and there are three bayonets for row.
The utility model has the advantages that：
The utility model carries out towing pad by the bayonet that kelly is equipped with to different airplane wheels, solves towing pad size
The problem of needing equipped with dedicated draw bar with liftoff height also difference, and the machine for being suitble to Multiple Type winged is given birth in favor of improving
Efficiency is produced, while the quantity of draw bar can be reduced, it is all very favorable to save producing cost.
Certainly, any product for implementing the utility model does not necessarily require achieving all the advantages described above at the same time.
