Arc-shaped guide rail cooperation；First gear cooperation in rack gear and rear body coupling mechanism in front compartment bindiny mechanism.Work as square column
For pins position when triggering in mounting blocks, under the action of rectangular pin, third compressed spring is in tensional state.In two adjacent vehicles
During compartment connects, trunk is moved forward relative to front compartment；Trunk forward movement just will drive connection side's shape cylinder to
Preceding movement；It connects square tube and moves forward drive support mounting plate forward movement；Support mounting plate moves forward band movable gear shaft
It moves forward；On the one hand gear shaft, which moves forward, drives first gear to move forward；On the other hand gear shaft, which moves forward, to be driven
Swinging connecting rod moves forward；Swinging connecting rod, which moves forward, drives arc-shaped guide rail to move forward；When trunk is in moving process
When the rack gear in first gear and front compartment bindiny mechanism in middle rear body coupling mechanism contacts, in rear body coupling mechanism
Arc-shaped guide rail is also just contacted with the curved track shell in front compartment bindiny mechanism；Trunk continues to move at this time, in the work of rack gear
It just can rotate with lower first gear；The rotation of first gear rotation driven gear axis；Gear shaft rotation drives swinging connecting rod to swing；
Swinging connecting rod, which is swung, drives arc-shaped guide rail to swing；Arc-shaped guide rail swing will make arc-shaped guide rail be nested on curved track shell
In guide-track groove；In this state, arc-shaped guide rail and curved track shell are integrated, i.e. arc-shaped guide rail and curved track shell phase is for front truck
Compartment moves forward together；Meanwhile first gear is moved forward also relative to rack gear；I.e. first gear is in rotation in the process
State；First gear rotation just will drive arc-shaped guide rail swing；Arc-shaped guide rail will gradually be nested in the guide rail on curved track shell
In slot；Curved track shell phase front compartment is moved forward together will by connecting plate drive guide pad relative to front compartment forward
It is mobile；Guide pad forward movement will compress the first compressed spring；In guide pad moving process, when guide pad and two limit
When structure contacts, due to triggering the effect of corner block, guide pad will compress position limiting structure and make position limiting structure towards corresponding
Guiding mounting groove is mobile to the side for being equipped with third compressed spring；When guide pad in moving process well beyond position limiting structure
On triggering corner block when, under the action of corresponding four the second compressed springs, two position limiting structures will move out again
It is oriented to mounting groove；Position-limiting action is played to guide pad by two position limiting structures；And arc-shaped guide rail and curved track in this case
Position limiting slide block contact on the inside of shell；First gear is contacted with limit corner block simultaneously；Under the action of limiting corner block, on the one hand
First gear will move down；First gear, which moves down, just will drive gear shaft and moves down；Gear shaft moves down just
Support mounting plate be will drive to lower swing；Support mounting plate will compress leaf spring to lower swing and make power on leaf spring；Leaf spring will
Support mounting plate is transmitted to compressing force thereon to be transmitted on connection square tube；Connection square tube transmits that force to trunk
On；So that the friction between the wheel and railway rail installed on trunk increases；Pass through the wheel and train installed on trunk
Friction between rail is to absorb the impulse force that trunk continues to move along；Another aspect first gear teeth on limit corner block
Under the action of continue to rotate；I.e. arc-shaped guide rail continues to swing relative to curved track shell；Arc-shaped guide rail continues relative to curved track shell
Swing will compress position limiting slide block and position limiting slide block is slided；Position limiting slide block sliding will compression shock absorption spring；Pass through damping bullet
Spring absorbs the impulse force that trunk continues to move along.Absorbed in the present invention by damping spring a part of trunk continue to
The impulse force of preceding movement；And remaining impulse force is absorbed by the friction between the wheel and railway rail installed on trunk；It is made
With being to prevent the friction between the wheel installed on trunk and railway rail larger and trunk is made to turn on one's side.When arc is led
When rail is nested in completely on the inside of curved track shell, front compartment and trunk are just connected and are finished；In the mistake that front compartment and trunk disengage
Rectangular pin is released corresponding column pin hole by corresponding square hole using rectangular drift by Cheng Zhong, people；At this time in third pressure
Under the action of contracting spring, position limiting structure be will be moved on the inside of guiding mounting groove；Front compartment is moved forward relative to trunk, i.e.,
Guide pad will be moved forward relative to triggering mounting blocks；Curved track shell and arc-shaped guide rail are in integrality at this time；Before institute
Compartment will make first gear mobile relative to rack gear relative to trunk forward movement；I.e. first gear just can rotate；The
The rotation of one gear rotation driven gear axis；Gear shaft rotation drives swinging connecting rod to swing；Swinging connecting rod, which is swung, drives arc
Guide rail is swung；Arc-shaped guide rail swing will make arc-shaped guide rail progressively disengage the guide-track groove on curved track shell, last completely disengaged；
I.e. front compartment and trunk disengage at this time.
Due between curved track shell and arc-shaped guide rail during front compartment and trunk connection and disengagement in the present invention
For cambered surface contact；Contact area is big；The loss generated by friction is small；So the long service life of compartment bindiny mechanism；This hair
Adjacent two compartment may be implemented by curved track shell and arc-shaped guide rail in bright and connect locked function automatically；Pass through limit in the present invention
The forward impact force of trunk can be converted to the frictional force between the wheel and railway rail installed on trunk by position corner block,
And then shorten the distance of brake.The direction of the impact force buffered in the present invention by damping spring and limit triangle block buffering punching
Hit the contrary of power；And it can cancel out each other in a top degree.In the present invention during the connection process by front compartment and trunk
Caused by the host buffer structure of impact force and the connection structure of front compartment and trunk be combined together；Structure is simple；Consumptive material is small.
Relative to traditional railway carriage interconnection technique, the train railway carriage bindiny mechanism that the present invention designs connects in adjacent two compartment
On the one hand the impulse force that a part of trunk continues to move along is absorbed in termination process by damping spring；And remaining smaller punching
Power is absorbed by the friction between the wheel and railway rail installed on trunk；Its effect is the vehicle for preventing from installing on trunk
Friction between wheel and railway rail is larger and trunk is turned on one's side；Simultaneously by installing on damping spring and trunk
Friction between wheel and railway rail prevents impact caused by adjacent two compartment connection procedure.
