Groove a1.1 and U of U-shaped it is respectively arranged with on the other end of coupler head 1 and coupler butt 2
The groove b2.1 of shape, groove a1.1 insert in groove b2.1, are provided with chain in the recess of groove a1.1
Hook 7, hook-screw coupling 7 is connected with connecting pin 3, hook-screw coupling 7 around connecting pin 3 in the recess of groove a1.1
Rotate, groove a1.1 is provided with connecting pin bores a1.2 and dowel hole a1.3, groove b2.1 is arranged
Having dowel hole c2.4, connecting pin bores b2.2 and dowel hole b2.3, connecting pin 3 is positioned at a pair connecting pin
In hole a1.2 and a pair connecting pin bores b2.2, alignment pin 4 is positioned at dowel hole a1.3 and a pair alignment pin
In the b2.3 of hole；
A pair dowel hole b2.3 overlaps with longitudinal direction of car centrage, and a pair dowel hole c2.4 is positioned at car
The side of hook afterbody 2.
One end of coupler head 1 is connected by coupler knuckle pin 11 with hook bolt 8, and hook bolt 8 can be around coupler knuckle pin 11
Rotate, it is achieved company's extension, locking and the unlocking function of hitch；
Hook bolt 8, gib head 1, coupler butt 2 all use E level steel；
The fifth wheel profile of coupler head 1 meets 13A (13B) hitch of TB/T2950 standard and connects
Profile 1.4, it is stipulated that the pattern draft of locking face, hitch joint gap is 11.5mm ± 1mm, compare
The 19.5mm gib head joint gap of AAR10A, hitch joint gap reduces 40%, hence it is evident that improve car
Run dynamic performance, improve the stress collected state in the S face of hook bolt 8, improve vehicle and portion
The service life of part；
Hook bolt 8 uses 13B type hook bolt, has all functions of 13B type hitch, can with 13 types, 13A,
13B type hitch is connected to the hanging；
As shown in Figure 4, in the nose of hook bolt 8, intracavity sets three reinforcements 8.1, three reinforcements 8.1
Further increase structural strength and the fatigue reliability of hook bolt, reduce hook bolt fracture, add hook bolt
Service life,
Latch 5 prevents connecting pin 3 from scurrying out, it is to avoid the generation of the driving accident thus resulted in；
First chain 6 prevents connecting pin 3 from losing, and the second chain 12 prevents alignment pin 4 from losing；
The material of coupler head 1, coupler butt 2 and hook bolt 8 all uses the E level meeting AAR standard
Steel；The material of connecting pin 3, alignment pin 4 and latch 5 all uses high strength alloy steel 40Cr；
Couple yoke 9 is greatly improved hitch intensity of the present utility model and reliability, and train can be avoided to transport
In row, longitudinal impact force is excessive and cause the destruction of hitch connection member, also can improve the traction of train simultaneously
Weight.
A kind of using method for the double-acting hitch of rolling stock of this utility model is: when vehicle with from
When motor-car hook is connected to the hanging, it is ensured that the center of coupler head 1 and longitudinal direction of car center superposition, connecting pin 3 is inserted
Entering in a pair connecting pin bores a1.2 and a pair connecting pin bores b2.2, alignment pin 4 inserts dowel hole b2.3
In, locking coupler head 1 and coupler butt 2, it is achieved the company of automatic car coupler hangs and transmitting forces function,
Latch 5 prevents connecting pin 3 from scurrying out, it is to avoid the generation of the driving accident thus resulted in, and the first chain 6 is prevented
Only connecting pin 3 is lost, and the second chain 12 prevents alignment pin 4 from losing；
Such as Fig. 2, when vehicle is connected to the hanging with screw coupling vehicle, coupler head 1 rotates to coupler butt
2 lateral, alignment pin 4 inserts in dowel hole c2.4 locking coupler head, and hook-screw coupling 7 is around connecting pin
3 go to longitudinal direction of car center position, are connected to the hanging with screw coupling, and transmit longitudinal pulling force, and latch 5 is prevented
Only connecting pin 3 is scurried out, it is to avoid the generation of the driving accident thus resulted in, the first chain 6 prevents connecting pin
3 lose, and the second chain 12 prevents alignment pin 4 from losing.
Alignment pin 4 is mainly accurately positioned the operating position of coupler head 1, is not subject to hitch and even hangs work
Time longitudinal traction and impulsive force, connecting pin 3 is to accept longitudinal traction and longitudinal impact force
Critical piece, the duty of hitch mainly undertakes longitudinal pull strength and impulsive force, if location
Pin 4 and connecting pin 3 exist together lengthwise position, due to dowel hole a1.3, the tolerance of dowel hole b2.3
More than connecting pin bores a1.2, the tolerance of connecting pin bores b2.2, withstand shocks or pull strength in coupler head 1
Time, connecting pin 3 mainly transmits impulsive force and pull strength, and alignment pin 4 undertakes stress hardly；
If dowel hole a1.3 is positioned at gib head 1 side, alignment pin 4 positions hitch in gib head 1 side
During the duty of head 1, when coupler head 1 is born from longitudinal pull strength and impulsive force,
Owing to alignment pin 4 and connecting pin 3 be not on same longitudinal centre line, it is in lateral attitude arranged side by side, fixed
Position pin 4 also by bearing the longitudinal pull strength of part and impulsive force, so easily causes the damage of alignment pin 4
Going bad and the abrasion of dowel hole a1.3, Application No. 200620035172.3, notification number is
200992210, the day for announcing is why 2007.12.19 takes side to position, because the phase of its gib head 1
Closing lengthwise position size little, it cannot can only be located at side at lengthwise position Design Orientation pin-and-hole a1.3,
And we solve this problem very well by lengthening the longitudinal length 80mm of gib head 1.
One of the present utility model for the double-acting hitch of rolling stock by arrange 13B type hook bolt 8,
13A (13B) hitch connects profile, first chain the 6, second chain 12, latch 5 and couple yoke 9；Hook
Tongue 8 improves hitch intensity, and 13B hitch connects profile 1.4 and reduces hitch joint gap, reduces
Longitudinal impact force in train operation, couple yoke 9 improves the trailing weight of hitch intensity and train, keeps away
Having exempted from the excessive hitch fracture caused of longitudinal impact force in train operation, latch 5 prevents connecting pin 3 from scurrying out,
The generation of the driving accident thus resulted in, the first chain 6 is avoided to prevent connecting pin 3 from losing, the second chain
12 prevent alignment pin 4 from losing.Features described above drastically increases hitch intensity of the present utility model with reliable
Property, longitudinal impact force in train operation can be avoided excessive and cause the damage of hitch connection member, the most also
The trailing weight of train can be improved and run safety.
