Degree, key technology one, it is that gap is little, generally no greater than 0.5 millimeter, prevent accumulated error larger；Key technology two, length and width
Size is consistent with joint with three degress of freedom seat, can exchange.
Joint with three degress of freedom seat：As Fig. 7,8, joint with three degress of freedom seat is by rotating shaft, two chain links, female seat II and pin shaft II group
Become, there is three degree of freedom.Chain link I in two chain links is welded in rotating shaft, before rotating shaft is turnably fixed on by jam plate
Gun carriage on, be installed with bearing pin in the chain link II in two chain links, bearing pin two ends are fixed on gun carriage below by female seat II, chain link
It is provided with adjustable plate between II and female seat II.
Two kinds of hinged seat arrangement modes are preferably：First Series 211, or second series 12, or the 3rd be 1
22, note：1 represents single-degree-of-freedom hinged seat；2 represent two degrees of freedom hinged seat.
As Fig. 9,10, zero-deviation tractor trailer train by drive gun carriage, common gun carriage, single-degree-of-freedom hinged seat, two degrees of freedom hinge
Joint chair, extension spring, steering mechanism and electrical control etc. form.One driving gun carriage can drag several common gun carriages of connecting, and claims
Drag combination for dynamic, one dynamic to drag combination can drag how many common gun carriages to be determined by road conditions and transport capacity.Several move
After dragging combined serial to get up, connect again a driving gun carriage in one end of no driving, the driving gun carriage at permutation two end is respectively installed
A set of steering mechanism, an electric control box or an operational control room.Drive between gun carriage and common gun carriage, common gun carriage with
Between common gun carriage, linked up by single-degree-of-freedom and joint with three degress of freedom seat, two extension springs become splayed to be symmetrically mounted on
Hinged seat both sides, two ends fixation hinged with adjacent two gun carriage vehicle frames, splay horn mouth is consistent with travel direction.All drivings
The power line of gun carriage accesses electric control box or control room.
The present invention solves the series of problems that existing tractor trailer train exists.
1st, solve the problems, such as to take turns deviation.First, after each gun carriage of the present invention is coupled by hinged seat, all fast pulleys
Axle, is provided with turning function, and fixing wheel shaft also just becomes steering wheel shaft, and its role is the effect of steering wheel shaft,
The distance at wheel shaft in front and back's hinged seat center is equal, and steering behaviour is consistent, and the track of therefore series connection gun carriage is consistent, is not turned round partly
Footpath size impact；（As Figure 11）.According to formula（1）Understand, during b=0, c=0.Second, reducing the gap of hinged seat（Original interstice
About 10 millimeters narrow down to 0.5 millimeter）Reduce the wheel deviation causing in this gap；Third, wriggling in side also brings along wheel deviation, such as big gun
Car is towed Lixing when sailing, when bend traction travels, the direction of the pulling force F to a rear gun carriage P2 for the previous gun carriage P1 always and
The travel direction of a gun carriage P2 has an angle a1 afterwards, therefore, always has the travel direction perpendicular to gun carriage P2 for the component F2,
Point to the center of circle, in the same manner, the travel direction that gun carriage 2 draws the counteracting force F' and gun carriage P2 that a rear gun carriage P3 produces also has one
Angle, therefore also always has the travel direction perpendicular to gun carriage P2 for the component F2', points to the center of circle.One, if F2+F2' is more than big gun
During the force of sliding friction on car P2 and ground, gun carriage P2 will break away；Therefore, for one is moved and drags combination, near driving big gun
The common gun carriage stress of first of car is maximum, and to this common gun carriage force analysis, F2+F2' is less than this common gun carriage and ground
The force of sliding friction in face, then this moves and drags combination will not break away.Two, for wheel, F2 and F2' can produce a direction phase
Anti- arm of force square is although the arm of force is equal, but F2 is more than F2', and the moment of torsion that therefore F2 produces can make gun carriage P2 have one to inner circle row
The trend sailed.F2 is the main cause causing train driving side to wriggle and crawl.In hinged seat both sides, two extension springs are installed, become eight
Font, two ends respectively with the adjacent hinged fixation of gun carriage vehicle frame, horn mouth is consistent with travel direction, when bend traction travels, outward
The extension spring elongation on side, the extension spring of the inside is shortened, and the part of extension spring specific elongation produces pulling force S, for gun carriage P2, Qian Houfen
Not Shou Dao tension spring tension S and S', S produce a component S2, perpendicular to the travel direction of gun carriage P2, away from the center of circle, S' also produces
One component S2', perpendicular to the travel direction of gun carriage P2, points to the center of circle, S2 and S2' is equal in magnitude, in opposite direction, for gun carriage
For P2 axial direction, cancel out each other, for travel direction, produce each a moment of torsion and be superimposed, make gun carriage P2 have one
The trend travelling away from the center of circle.The torque direction that this moment of torsion and F2 produce is contrary, controls pulling force S and S2 of extension spring, make this two
Individual moment of torsion is offset, and without lateral moment, train-side is wriggled and phenomenon of crawling eliminates automatically, so that wheel deviation is gone to zero.
In the same manner, as gun carriage travelled by thrust when, when bend thrust travels, when splayed extension spring is installed, horn mouth and traveling
Direction is consistent, could suppress to take turns deviation and change of crawling.
It is conceivable that, during the out-of-flatness of ground, gun carriage unbalance loading, pull strength change etc., these unbalance loadings and change can be brought also
Produce a component, so that gun carriage side is wriggled and crawl.It is certain for pavement roughness, the generally less than three meter ruler discrepancy in elevation
When 100 millimeters, comprehensive analysis, when train running speed is less, this component recited above is smaller, and direction is miscellaneous
Disorderly, the wheel deviation therefore brought and change of crawling are all smaller, do not affect the control of train, therefore ignore.
In sum, it is symmetrically installed extension spring in hinged seat two side, becomes splayed, horn mouth is consistent with travel direction, extension spring
Active force always want to train straight-line travelling, and deviate straight-line travelling force direction contrary, the working pulling force of extension spring and
Angle determines the size of this power.A kind of suitable extension spring and the angle of its installation therefore can be found, offset side wriggling required
Active force, eliminate wheel deviation.Computational methods are slightly.
2nd, solve startup and brake jiggly problem.Multipoint Drive is braked with multiple spot, first, reducing startup and system
Dynamic quality, is easy to start and braking, second, centralized Control, starts successively and braking, alleviates the impact starting with braking and carries
Lotus, eliminates and springs up phenomenon.
3rd, solve the problems, such as not adapting to pavement roughness.Gun carriage itself mechanism unit is less, and joint with three degress of freedom
The intervention of seat, increased gun carriage（Or driving gun carriage）Degree of freedom, can rotate up and down, make wheel stress than more uniform.
Solve the problems, such as that the three-wheel wheel stress that lands is larger.
4th, solve the problems, such as tractor trailer train one-way traffic：Train two end is assembled with steering mechanism and operational control room,
Driver can select two ends to drive, and solves the problems, such as tractor trailer train one-way traffic.
5th, can there are longer train and larger load：1）, solve train longer when control problem, by above 1,
Understand, wheel deviation close to zero, when train is longer, wheelmark still controlling, within range；2）, solve startup ask with braking
Topic, from above 2, only increase several driver elements when train is longer, remain centralized Control, start successively and system
Dynamic, do not affect normal startup and the braking of train；3）, solve the Rigidity of train：
The rigidity of train：It is assumed that train is placed on an irregular road surface, center applies one respectively along big gun end to end
Longitudinally opposite external force F of car, F by little increase, when F reaches F2When tractor trailer train deformation, F2It is referred to as the rigidity of tractor trailer train.F comes
Source：Derive from concave arc road surface when one train is longer, it two derives from corollary equipment, corollary equipment to train be applied with one outer
Power, the external force superposition that this external force can be brought with concave arc road surface.F is not within train control territory, but can pass through repeatedly to try
Test and calculate the value learning F.Ftga will destroy the stability of gun carriage, and tga is by pavement roughness, concave arc radius, bending radius
Deng decision；The length of train, height of C.G., ground irregularity degree and hinged degree of freedom equivalence are bigger, F2Less；Width, weight
F bigger with frictional force2Bigger, and the direction of train deformation is always along the free direction of hinged seat.It is not difficult to find out width, matter
Amount, center of gravity and surface evenness are limited by use requirement and objective condition, but hinged degree of freedom can consider change, and train is divided
For the analysis of some junior units, can preferably go out rational articulated manner in the range of rigidity and adaptation road surface ability condition
（A.B.C）, make KFtga ＜ F2,（Train establishment condition, K：The coefficient of stability）.
In sum, the length of train is mainly determined by its rigidity, undoubtedly on flat road surface train can have larger
Length；The rigidity of train to be taken into full account on uneven road surface, train length is shorter.Train is supported the use with miscellaneous equipment
When, it is considered as the impact of miscellaneous equipment, example, and when scale ribbon conveyer supports the use, be considered as scale belt conveying chance
Apply the external force of a longitudinal direction to train, this external force can affect the rigidity of train.
