The method of work of buffer coupling：A kind of left end of vehicle bumper connector is connected and pacified with bearing pin by pin-and-hole A
On the drive division of vehicle, the right-hand member of vehicle bumper connector is connected with bearing pin by pin-and-hole B and is arranged on being led for vehicle
Draw in portion, the drive division of vehicle is driven by vehicle bumper connector to be moved together by tractive unit, for example vehicle bumper is connected
Device is used for drawbar trailer, and the left end of vehicle bumper connector is connected and is arranged in driving headstock with bearing pin by pin-and-hole A, car
The right-hand member of buffer coupling is connected and is arranged on trailer compartment with bearing pin by pin-and-hole B, and driving headstock passes through vehicle bumper
Connector drives trailer compartment to move together.
When towing vehicle starts, the drive division of vehicle is moved first, and driving force is acted on vehicle by connecting bearing pin
On the left piston bar 2 of buffer coupling, band piston 9 forms movement tendency to the left, and driving force is further through piston 9, first sleeve
8th, the first spring base 7, the first preloaded spring 6, left end 4, left end cap 3, cylinder body 5, right end cap 15, right plunger 16, and pass through company
Pin axle be delivered to vehicle by tractive unit, if vehicle is less than the first preloaded spring 6 by the starting inertia load of tractive unit
Preload force when, the first preloaded spring 6 will not be compressed, and will not be produced between vehicle bumper connector left pin-and-hole A and right pin-and-hole B
Suitable displacement, vehicle bumper connector can be straight by vehicle bumper connector equivalent to the drive division in rigid state, vehicle
Being moved together by tractive unit for tape splicing motor-car, completes the starting of towing vehicle；If vehicle is born by the starting inertia of tractive unit
When carrying the preload force more than the first preloaded spring 6, the drive division of vehicle drives left piston bar 2, piston 9, the by connecting bearing pin
Sleeve 8, the first spring base 7 overcome the precompression of the first preloaded spring 6, and to left movement, on the one hand the first preloaded spring 6 meeting be entered
One step compress, absorb vehicle launch during impact energy, on the other hand, due to piston 9 produced in cylinder inner bore 35 to
Left motion, the work fluid in the left working chamber 25 of vehicle bumper connector can flow to vehicle bumper company by damping flow channel 23
Connect in the right working chamber 24 of device, form damping drag, consume the impact energy during vehicle launch, so, when vehicle is drawn
The starting inertia load in portion more than the first preloaded spring 6 preload force when, vehicle bumper connector equivalent in flexible state,
Vehicle bumper connector absorbs the impact energy in towing vehicle starting process by the first preloaded spring 6, while passes through damping
Impact energy in the damping action consumption towing vehicle starting process of runner 23, realizes the smooth start of towing vehicle.
When towing vehicle normally travel, the tractive force of towing vehicle is more stable, and in vehicle bumper connector, first is pre-
The precompression for carrying spring 6 is set greater than the tractive force of towing vehicle normally travel, so, when towing vehicle normally travel,
The driving force of vehicle drive portion drives left piston bar 2, piston 9, first sleeve 8, the first spring base 7, first by connecting bearing pin
Preloaded spring 6, left end 4, left end cap 3, cylinder body 5, right end cap 15, right plunger 16, and it is delivered to vehicle by connecting bearing pin
By on tractive unit, because the precompression of the first preloaded spring 6 is set greater than the tractive force of towing vehicle normally travel, first is pre-
Spring 6 is carried to be compressed, piston 9 will not also produce motion to the left, the left pin-and-hole A of vehicle bumper connector and right pin-and-hole B it
Between will not produce suitable displacement, vehicle bumper connector is equivalent in rigid state, the drive division of vehicle and being led for vehicle
Draw and be rigidly connected equivalent to formation between portion, ensure towing vehicle normally travel.
When towing vehicle is braked, the effect that motional inertia by tractive unit be present of vehicle, the inertia caused by tractive unit
Power drives right plunger 16, cylinder body 5, right end cap 15, right end 13, the second preloaded spring 12, second spring seat by connecting bearing pin
11st, the second sleeve pipe 10, piston 9, left piston bar 2, left plunger 1, and be delivered to by connecting bearing pin on the drive division of vehicle.If
Vehicle drive portion and vehicle are less than the precompression of the second preloaded spring 12 by the relative brake impulsive force between tractive unit, and second is pre-
Further compression will not be produced by carrying spring 12, and suitable position will not be produced between vehicle bumper connector left pin-and-hole A and right pin-and-hole B
Move, vehicle bumper connector is equivalent in rigid state；If vehicle drive portion and vehicle are by the relative system between tractive unit
Dynamic impulsive force is more than the precompression of the second preloaded spring 12, and vehicle drives right plunger 16, cylinder by tractive unit by connecting bearing pin
Body 5, right end cap 15, right end 13 are produced relative to piston 9 to left movement, and on the one hand the second preloaded spring 12 can be further
Compression, the impact energy during vehicle launch is absorbed, on the other hand, because cylinder body 5 equivalent to piston 9 produces fortune to the left
Dynamic, the work fluid in the right working chamber 24 of vehicle bumper connector can flow to a vehicle bumper connector left side by damping flow channel 23
In working chamber 25, damping drag is formed, consumes the impact energy during vehicle launch, so, when vehicle rising by tractive unit
When dynamic inertia load is more than the preload force of the second preloaded spring 12, vehicle bumper connector is equivalent in flexible state, vehicle
Buffer coupling absorbs the impact energy in towing vehicle braking procedure by the second preloaded spring 12, while passes through damping flow channel
Impact energy in 23 damping action consumption towing vehicle braking procedure, realize the gradual braking of towing vehicle.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
