Description
Technical field
The utility model is related to airplane ground support equipment system regions, to reducing traction more particularly in pulling equipment
The buffer design of the shock loadings such as pulling force, thrust, to reduce the shock loading that undercarriage is subject in distraction procedure, carries
A kind of airplane tractor buffering and overload protecting mechanism in undercarriage life-span high.
Background technology
Aircraft floor traction is divided into has rod-type to draw and drawn without rod-type, has rod-type to draw tractor and is connected by draw bar
Aircraft, to prevent undercarriage to be subject to impact injury when traction starts with aircraft brake, it is necessary to be designed on draw bar slow
Flushing device, can be provided simultaneously with drawing, press pooling feature, and be provided simultaneously with overload protection function.
The content of the invention
The purpose of this utility model is directed to above-mentioned deficiency and defect, solve nose-gear because of towing aircraft starting, stop
During car by overload pulling force, thrust, impulsive force and the problems such as cause aircraft nose landing gear structure to damage, there is provided a kind of airplane tractor delays
Punching and overload protecting mechanism.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of airplane tractor buffering and overload protecting mechanism, including nut one, curved washer one, pull bar, bolt, connection
Joint, bail, curved washer two, overload bolt, bushing, compression spring, back-up ring one, back-up ring two, nut two, connecting tube, pad
Circle, nut three, mobile jib, pivot pin, wherein：Mobile jib is connected by pivot pin matching washer, nut three with connecting tube, bushing, is connect
Head, back-up ring one, compression spring, back-up ring two, nut two are sequentially arranged on pull bar in order, and pull bar passes through the supporting spiral shell of overload bolt
Female one, curved washer one and curved washer two are connected with bail, and whole rod assembly is put into mobile jib and is bolted.
The utility model has the advantages that：By the design of each buffering and overload limiting mechanism, nose-gear is solved because of traction
When aircraft starting, parking by overload pulling force, thrust, impulsive force and the problems such as cause aircraft nose landing gear structural damage, it is ensured that
When aircraft is effectively protected during towing aircraft when overload impact and barbarous operation is born nose-gear it is injury-free and
Destruction, effectively improves the service life of undercarriage, can be provided simultaneously with drawing, pressing pooling feature, and be provided simultaneously with overload protection work(
Energy.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is assembling structure schematic diagram of the present utility model.
Reference：Nut 1, curved washer 1, pull bar 103, bolt 104, jointing 105, bail
106th, curved washer 2 107, overload bolt 108, bushing 109, compression spring 110, the 111-1 of back-up ring one, the 111-2 of back-up ring two, spiral shell
Female 2 112, connecting tube 113, packing ring 114, nut 3 115, mobile jib 116, pivot pin 117.
Specific embodiment
Embodiment 1, a kind of airplane tractor buffering and overload protecting mechanism, including nut 1, curved washer 1,
Pull bar 103, bolt 104, jointing 105, bail 106, curved washer 2 107, overload bolt 108, bushing 109, compression
Spring 110, the 111-1 of back-up ring one, the 111-2 of back-up ring two, nut 2 112, connecting tube 113, packing ring 114, nut 3 115, mobile jib
116th, pivot pin 117, wherein：Mobile jib 116 is connected by the matching washer 114 of pivot pin 117, nut 3 115 with connecting tube 113, bushing
109th, jointing 105, the 111-1 of back-up ring one, compression spring 110, the 111-2 of back-up ring two, nut 2 112 are sequentially arranged in order
On pull bar 103, pull bar 103 by the matching nut 1 of overload bolt 108, curved washer 1 and curved washer 2 107 with
Bail 106 is connected, and whole rod assembly is put into mobile jib 116 and is fixed by bolt 104.
Operation principle of the present utility model：
Energy when starting, parking, emergency brake when drawing is absorbed using compression spring 110, mitigation is rushed to undercarriage
Hit, so as to protect undercarriage injury-free.When hauled load of the tractive force more than undercarriage, overload bolt 108 breaks in addition
Split, draw bar departs from tractor, so as to protect undercarriage.
Buffered during by pulling force：When the tension masterpiece used time, pull bar 103 is drawn out from draw bar mobile jib 116, back end of tie rod
The 111-2 of back-up ring two and nut 2 112 moved forward with pull bar 103, because the 111-1 of spring at front end back-up ring one is not subjected to displacement,
The 111-2 of back-up ring two reaches cause spring-compressed, so as to play cushioning effect during by pulling force；
Buffering when being stressed：When being acted on when being stressed, pull bar 103 is pushed into draw bar mobile jib 116, pull bar front end
The 111-1 of back-up ring one is moved rearwards by with pull bar, because the 111-2 of spring rear end back-up ring two is limited not by connecting tube 113 and pivot pin 117
It is subjected to displacement, the 111-1 of back-up ring one reaches cause spring-compressed, cushioning effect when being stressed so as to play.
Overload limitation：When shock loading is excessive, impact energy can not be fully absorbed beyond spring, for avoid undercarriage because
Impulsive force crosses macrolesion, and an overload bolt 108, when by greater impact power, mistake are set between bail 106 and pull bar 103
Carry bolt 108 to cut, draw bar and tractor are separated.
