Description

A kind of guide wheel rail vehicle and track

Technical field

The present invention relates to field of track traffic, in particular to a kind of guide wheel rail vehicle and corresponding track and line Road switching method.

Background technique

In Modern Traffic logistics field, rail traffic is important application form, fixes with route, driver behavior letter Single, low power consumption and other advantages have been widely used in the numerous areas of modern society's production, life.In urban transportation, The track vehicles such as light rail, subway, tramcar, guide rail electric car, monorail train provide greatly just to the trip of resident Benefit；In remote traffic, train, EMU for operating on the railway network etc. produce for national economy, life provides largely Visitor, shipping power；On plant produced line, in the tunnel of mining area, rail flat car and suspension type monorail transport vehicle are factories and miness logistics Common tool.

Conventional rails traffic is suitable for long range between the fixed point of space, the transport task of large conveying quantity, above-mentioned rail traffic Means of transport is detailed haulage time plan need to usually to be formulated, in the task of transport along fixed line operation really was planned Embodiment on need to rely on the Large Infrastructure Projects such as large-scale platform, website, hinge, have apparent public attribute.With it It is mostly firm broad large-size box or plate that task feature was adapted, which is the car body of rail vehicle, and turning radius is larger.Cause This, no matter in application mode or structure type, rail traffic lacks flexibility.

Currently, the running gear of conventional rails vehicle uses bogie form, the arrangement of wheel-rail match relationship and bogie Spacing, installation form etc. limit the turning radius of conventional rails vehicle to reducing within hundred meter levels；In light rail and rail electricity After vehicle field is using articulated bogie or single-axle bogie, the turning radius of vehicle be can control to ten meter levels；And in highway Field of traffic, is turned to using rotation to, bridge or the vehicle of articulation steering can but control turning radius within ten meters.More than Comparison is it follows that rail vehicle should control wheel to reducing turning radius, improving steering flexibility in terms of vehicle structure The number of axle and distance between axles increase hinged link.

In terms of circuit switching, widely used railway locomotive, tramcar, magnetic suspension column either in public transport Monorail transit vehicle on vehicle or plant produced line, generally existing in drive, require its vehicle line have can efficiently, It is accurately realized the ability of switching.For a long time, diversified forms have been developed in the railway system and modern tram field Track switch and goat (or rail-changer equipment of entitled point switch), monorail City Rail Transit System use articulated type road Trouble is able to satisfy the demand of route operation and forms mature application system --- vehicle is adapted to the positive action of track Space structure demand in route choosing.There is old-fashioned tramcar in a manner of crowded trouble by switch zones, separately with the quilt of track It acts to adapt to space structure demand of the vehicle in circuit switching, this side for being only able to achieve switching and can not achieve selection Formula (disregarding inefficient cumbersome reversed interflow mode) has gradually been eliminated.

For above-mentioned track switch, vehicle needs to coordinate track state in which when selecting working line, no matter the operation of track switch Using the control of central schedule formula or the control of onboard wireless formula, all need to properly settle vehicle and rail-changer equipment cooperation when Between, speed and movement problem, it is more demanding to vehicle operation control, line arrangement etc..Switch zones are empty due to bending track and nocuousness Between one or more factors such as presence and coordinate the time requirement of track switch cooperation, need to limit the (outstanding by speed of vehicle It is laterally through speed)；The applicable joint turnout of various track switch, especially straddle-type single-track vehicle, since space hold is more, peace Full by factors such as limited speeds, the operation spacing of same route vehicle need to be limited strictly, this all affects Rail Transit System Operational efficiency, the gentle anti-interference ability of Automated water etc..In addition, existing switch structure is complicated, service life is significantly lower than general Logical track, it is more demanding to conserving, repairing.Therefore, rail vehicle realizes circuit-switched mode by existing track switch Though it is long-standing, using maturation, but still have many shortcomings, limit is formd to intensive application, the flexible dispatching of rail vehicle System.

In Modern Traffic logistics field, what importance was not weaker than rail traffic at all is highway communication, public in high speed daily Highway vehicle, truck combination, coach, bus, the small sedan-chair run on Class IV highway between road, urban road or even township are wild Vehicle, dumper etc. are resident trip, logistics provides convenient and fast approach.

Highway communication is more suitable for the transport task of medium and small freight volume between the random point of space, due to the vehicle knot of road vehicle Structure and steering structure flexible design, it is no matter former based on classical Ackermann steering principle or articulation steering principle or axle steer Reason,

It can allow road vehicle to realize lesser turning radius, more adapt to the route of industrial and mineral, resident compact district.The line of road vehicle Road switching by the control system of driver or automatic Pilot according to mission planning, location information real-time control, transportation route and Period planning flexibly can be formulated and be optimized and revised according to reality factor, have stronger specificity.The forward road of vehicle It in addition to should have unobstructed condition, does not need to make any adjustments, can theoretically meet the adjacent vehicle in front and back in how close secondary transport task The different direction of advance of selection without the requirement that workshop interference occurs, task is paused, be conducive to the utilization rate for improving road and Traffic efficiency；In actual application, road vehicle because of its maneuverability, lack traffic congestion, accident caused by United Dispatching It takes place frequently, causes a large amount of human and material resources to waste, be the current insoluble problem in highway communication field.

In permanent social practice, although rail traffic and highway communication respectively occupy phase by respective plurality of advantages When the field that is widely applied, it is difficult to substitute completely each other, but respective disadvantage also limits their development space.With society Urbanization deeply develop, urban compact degree improves, and discrete residential area is but difficult to largely disappear, PRT system, BRT system, nothing The new traffic organization method and technology such as people's driving are fast-developing, and rail traffic will such as adapt to this development trend, strive for highly dense The tasks in areas of degree, medium and small freight volume should then improve the flexible of its body structure and application mode in conjunction with the characteristics of road vehicle Property, it improves on the operational mode of vehicle, steering structure, steering mode and circuit switching selection mode, appoints transporting It is reformed in the embodiment of business, organizational form.

Summary of the invention

The big and circuit switching method the technical problem to be solved by the present invention is to the turning radius of current track vehicle Movement (based on positive action) based on track switch, and the composition of existing track switch and structure is complicated pass through such track switch and realize rail Height is required to the timing movement cooperation of vehicle and track when the switching in road, rail traffic vehicles intensive application is not easy to and flexibly adjusts It is whole.

To solve the above problems, being related to the invention proposes a kind of new track switching method and vehicle configuration based on this A kind of novel track vehicle and orbit form of method.The rail vehicle is able to achieve the corresponding walking of directive wheel in curved areas The accurate steering of wheel shaft, when facing route choosing, it is only necessary to can be switched to freely by adjusting the running gear of itself Expected route makes corresponding timing adjustment movement in composition, complicated switch zones without track to cooperate.

The configuration of the vehicle is bis- (vehicle) spindle guide wheel track vehicles, and (vehicle) axis corresponds to the row of vehicle running device Walk the centre of gyration of component.Every axis running gear assembly includes traveling wheel (driving or driven), directive wheel and wheel mounting structure Part etc., traveling wheel can be single wheel or bilateral (can be differential vehicle bridge, can also be bilateral independent hub) form, directive wheel and traveling wheel It is realized and is connected by the structural member of running gear.In addition, for operate in fork route on vehicle, for meet road choosing The needs select, switched, vehicle are also configured with guiding regulation device, for adjusting guided mode, the selection walking route of vehicle, lead It can be integrated on every axis running gear assembly to regulation device, also mountable in car body main structure (can be vehicle frame or bearing-type vehicle Body or framework beam) on.

There are two types of working principles for the guiding regulation device, first, the contact roller that guiding regulation device drives (can be considered and lead Positioned to the specific function of wheel) and the guide wheel group of running gear can realize and the combination in respective track face or separate, that is, be oriented to Regulation device executes different guide arrangement schemes by coming into force or failing for control each guide wheel group of running gear, and can root The states such as the flexible of guiding regulation device, rotation are adjusted according to the curvature of guide rail, guarantee the contact of guide wheel group, contact roller with guide rail State；Second, guiding regulation device can direct regulation and control running gear guide wheel group working condition, realize guide wheel group with not With the combination or separation of guide pass, i.e. guiding regulation device passes through coming into force or failing for the different guide surfaces of control guide rail, executes Different guiding schemes.It, can be for by the link mechanism or telescopic machine of hydraulic cylinder or electric cylinder drive in specific implementation form Structure, or for by the rotating mechanism of the drives such as motor, or in existing simultaneously link mechanism, telescoping mechanism, whirler on a trolley At least two forms in structure；Can also using vehicle in whole or in part component position of centre of gravity adjustment, or even traveling in air Power adjustment makes certain guide wheel groups be adjacent to guide rail.

For the requirement for adapting to small radius of curvature road, flexibly turning to for vehicle is realized, the vehicle can take two kinds of technologies Approach: one, the car body main structure of every axis running gear assembly and vehicle is hinged relationship；Two, car body is divided in two parts simultaneously Hinged, every axis running gear assembly is respectively connect with a car body and at least one is connected.Pass through above-mentioned hinged pass System can guarantee that by the turning center of vehicle, accurate steering is can be realized in the extending line intersection point of running wheel axis when turning to. It, can be between every set running gear assembly and car body or front and back two parts car body for being hinged on the basis of the articulated structure Between add hinged regulating element (can be hydraulic cylinder, electric cylinder or other actuating means) for keeping the driving stability of vehicle Property, driving direction auxiliary control and in no guide rail section operating and controlling vehicle direction of travel.

The running gear uses same set of traveling wheel on any route, according to whether providing driving force, the row " moved end " and " dragging end " can be divided by walking wheel, and when normally travel, an at least axis is moved end in traveling wheel used.When vehicle carries out line When road switches, vehicle can be using own drive power or inertia etc. by circuit switching region, and traveling wheel used can be all dynamic at this time Hold, drag end or both have concurrently.

The movement cooperation of track is required since the circuit switching method of the vehicle avoids vehicle, the road of the track Trouble region can be trapped orbit, simplify the Nomenclature Composition and Structure of Complexes of track switch.According to the specific constructive form of track switch, for limiting vehicle The route of one-way traffic, the track switch can class definition be select drawing lines branch off (after this track switch, there is branch in route and direction), Doubling track switch (after this track switch, a plurality of route and direction and be one)；For the route for allowing vehicle back and forth to travel, track switch is same When have the function of route choosing and merging.According to the structure of track switch, access section can be roughly divided into, deflection section, be detached from section. Access section be detached from section with and the similar track structure of connected common line, be the transition of track switch and common line.The rail Road can be built in ground roadbed, elevated bridge, subterranean tunnel according to specific line environment and functional localization, have universality.

The directive wheel and guiding regulation device are the key that realize the track switching method.Carrying out route choosing When, directive wheel can be divided into the configuration that at least two sets can individually support vehicle movement (certain distance) and combine or itself and axle structure It is combined etc. may make up at least two structural forms.The configuration combination of directive wheel and structural form combination are referred to as guiding scheme, with For two sets, " guiding A ", " guiding B " are referred to as.

Two sets of guiding schemes can mutually based on (supporting to travel over long distances), auxiliary (used in circuit switching, normally travel space-time Set or servo-actuated), every route of switching converts primary major-minor relationship；Can also it is clear it is wherein a set of based on, it is another set of supplemented by, and It remains unchanged；Can also two sets simultaneously based on, only select line switch zones use it is wherein a set of for circuit switching.Correspondingly, institute It states track and is equipped with two groups of tracks towards different line directions corresponding from this two sets of guiding schemes in switch zones, be with two Example, is referred to as " route A ", " route B ".

The rail vehicle uses at least a set of guiding at route A normally travel (there was only a route within the scope of section) Wheel group, by use guiding A for, another set of guide wheel group --- guiding B be in idle condition invalid state or with guiding A Run (in route A) together.When travel line needs are switched to B from A, before entering track switch deflection section, regulated and controled by guiding The movement of device (for guiding A or guiding B or both cooperation), determines guiding A and is oriented to spatial position state locating for B, make Guiding B is in the armed state that can cooperate with route B before vehicle enters track switch deflection section, while being oriented to that A is in can be with The state that route A is detached from realizes that the space structure of wheel track is coordinated.When vehicle through turnout passing deflect section after, vehicle along route B after Continue and sail, guiding A be in idle condition invalid state or be detached from section restore the state run together to same guiding B.

Track in the scheme is fixed in entire circuit switching link, therefore realizes that the key of switching is How guiding regulation device realization directive wheel smooth switching between the Different matching scheme of guide rail is passed through.Realize guide wheel group shape There are many modes for the adjustment of state or body construction, and need to be laid out Uniting with complete vehicle structure.The matching key of guiding wheel track exists Route bending is inevitably resulted in when the control between contact point wheel track, circuit switching, determines a circular arc, wheel track according to 3 points Contact point is at least three.For undertaking the running gear assembly of contact point at two, the axis of traveling wheel should be it at two and connect Perpendicular bisector of the contact line in the projection of orbit plane；For undertaking the running gear assembly of contact point at one, traveling wheel The setting that axis is in contact with it a position should only rise according to the hinged relationship flexible setting of each main component of vehicle to vehicle Support, position-limiting action, allow the accurate turning center of its axis runout vehicle.For guarantee contact point effectively adhere to along track and It does not depart from, " guide wheel embraces rail " or " guide rail wheel holding ", which can be used, (can be used on the inside of guide rail while being loaded into 2 guide wheel groups or guide rail There is revolute pair or guide pass to be slightly wider than the approach such as the approximate schemes of guide wheel diameter in face) structure type.To prevent in the inclined of track switch Turn section wheel track locking and hinder vehicle movement, can will take following measure: bending guide rail is arranged to variable cross-section rail, by guiding regulation dress It sets and adjusts guide wheel armful rail power etc..

The directive wheel may be arranged on the outside of car body (unilateral or bilateral), be also disposed in the middle part of car body.According to directive wheel Quantity, the working principle of Wheel/rail Match mode and guiding regulating device the guiding scheme of vehicle can be divided into two classes, it may be assumed that lead To wheel group Redundancy Design scheme and guiding wheel track compatibility of deformation scheme (irredundant directive wheel).When using Redundancy Design scheme When, the quantity of directive wheel is more than quantity needed for normal vehicle operation, by being oriented to regulation device control section directive wheel and leading The fitting or separation of rail can make the work of this directive wheel or the vacant a certain guiding scheme to select execution vehicle.When using change When shape coordinate scheme, all directive wheels all need to operate in vehicular motion, by guiding regulation device control directive wheel with The different guide surfaces of guide rail are bonded or separation, different guide surfaces can be made to act on or fail, and then realize vehicle guidance scheme Transformation.

The running gear structural assembly of the rail vehicle can centralized arrangement in vehicle roof.At this point, the carrying group of vehicle Part --- compartment (can be divided into " main cabin " and " loading space " by function) and car body main structure pass through structural member (sunpender or frame structure Deng) hanging connection.The height and horizontal cross section dimension of structural member should meet it and tie in the space that the interorbital of different routes shuttles Structure requirement.Running gear structural assembly can also be split in vehicle roof and bottom.At this point, running gear by long joint element for bar with Car body main structure is hinged, and cabin space is arranged between traveling wheel and directive wheel.Running gear structural assembly can also concentrate cloth It sets in vehicle bottom, compartment is mounted in car body main structure, closer to road vehicle.

The rail vehicle as fully functional transport facility remove with conventional rails vehicle some devices and Outside feature, can also have the feature of some road vehicles.Its power may be from the energy storage device provided for oneself, such as fuel tank, battery pack Deng also may be from contact net, third rail etc.；Its power device can be using internal combustion engine or motor and multiple combinations form Mixed power plant；Its power train can be using mechanical type, electric transmission form or hydrostatic drive form etc.；It is satisfaction Electrical equipment needed for operating normally, such as car light, air-conditioning are not enumerated item by item；It is to meet specific use and what is installed additional dedicated sets It is standby, such as crane arm, accumulating tank, temperature equipment do not enumerate item by item；It should also have a set of control being adapted with task orientation System has the functions such as signal transmitting and receiving, operation control, status monitoring, inter-vehicle communication, road conditions detection.

On operational mode, the circuit-switched manner of the rail vehicle at least support artificial (with vehicle or long-range) control with And one of computer controlled automatic, by driver, car-mounted computer or central dispatch system according to line indicating plate, position The information or signal of the offers such as sensor, satellite positioning device, scheduling system determine and to row to the operating status of vehicle It sails speed and direction is regulated and controled.For the rail vehicle except can be in addition to solo running, also visual mission requirements support more vehicles marshalling fortune Row, existence coordinated control mechanism is answered in vehicle and workshop at this time.

Specific embodiment

It describes in detail in conjunction with attached drawing to several specific embodiments of the invention, it is thin to non-emphasis and common design Section, which is not done, excessively to be repeated to protrude BROAD SUMMARY.

First specific embodiment

Fig. 1 illustrates a scene of embodiment utilization.In this embodiment, the running gear of vehicle is distributed in vehicle Lower part has guiding, driving capability and guide wheel running gear assembly --- the vehicle bridge for being integrated with guiding regulating and controlling mechanism for 2 sets simultaneously 140, two sets of vehicle bridge are by hingedly realizing that structure is integrated with vehicle frame 130.The detailed construction of complete vehicle structure and vehicle bridge as shown in Fig. 2, Compartment 160 is mounted on vehicle frame 130, vehicle bridge 140 except in the middle part of itself with vehicle frame 130 it is hinged in addition to, there are also steering assistance oil cylinders 150 It is stabilized direction.

Driving wheel 141 and vehicle bridge crossbeam 145 are connected (disregarding damping)；Directive wheel 142 is fixedly mounted on frame cross 145 Two sides.Directive wheel 143 is mounted on bracket 144, relative frame crossbeam pitching can be moved under the drive of guiding regulation oil cylinder 146 Make, to realize directive wheel 143 and the fitting of track and separate (i.e. 2 kinds of driving status), it is therefore an objective to adjust directive wheel 142 and rail The laminating degree in road, therefore it can be described as " contact roller 143 ", corresponding orbital plane is alternatively referred to as " seal face ".

Since vehicle bridge bilateral all has guiding regulation device (i.e. wheel group Redundancy Design scheme), therefore this vehicle has 4 kinds of guiding schemes, wherein bilateral rises at the same time with bilateral while the state that falls is suitable for the guiding demand of straight track；Two The scheme of a " side is risen, side is fallen " can realize route choosing and transformation of the vehicle in switch zones, cooperate corresponding rail Road can also travel over long distances in the section of single-sided tracks.In no guide rail section, by the locking of steering assistance oil cylinder 150 or specific Control action, it can be achieved that vehicle normally travel or injection, this be Special use operating condition, do not repeat them here.

According to the functional requirement of route, the track in this example should be vehicle and provide 2 ~ 4 guiding rail levels (containing 0 ~ 2 compression Face) and 1 carrying road surface, middle orbit inside guiding interplanar distance is slightly larger than the maximum width at vehicle bridge two sides directive wheel 142.This Illustrate common rail 110(in example only there is guide surface) and commutation track 120(be specifically divided into 121 and 122, there is guide surface And seal face, access Duan Junyu track 110 determine that the direction A is in the same direction).

When normally travel, for the scene shown in Fig. 1, vehicle is advanced in common rail 110 along the direction A, at this time vehicle bridge The contact roller 143 of two sides is in raised configuration (will not be in contact with track 110 and 120), as shown in Figure 3.In direction Straight track section, steering assistance oil cylinder 150 keep locking to guarantee that driving direction is stablized, and prevent the bad phenomenons such as snake hair It is raw；When meeting bend, steering assistance oil cylinder 150 is unlocked, and according to speed, location information etc. to 140 relative frame 130 of vehicle bridge Deflection angle is assisted amendment, guarantees the cornering stiffnesses of vehicle.

Before vehicle marches to and selects drawing lines trouble certain distance, for manned state, driver is according to road indicator Or the guide of terrestrial reference object or navigator fix signal etc. judges whether vehicle executes commutation in the track switch；For unmanned shape The task grouping of state, rail traffic scheduling system or vehicle self-carrying judges that vehicle is in the track switch according to vehicle location signal It is no to execute commutation.Scene as shown in Figure 1 need to judge that vehicle will continue to move on along track 121 or 122.

When judgement is that the more former direction A of track 122(is deflected) after, oil cylinder 146 need to be passed through in the access section of track 122 Regulation is fallen with the ipsilateral contact roller 143 of track 122 until reaching the state compressed with track 122, while unlocking steering assistance Oil cylinder 150.In the state that directive wheel 142 and contact roller 143 hold track 122 tightly jointly (as shown in Figure 3), before vehicle Into again 140 relative frame 130 of vehicle bridge returns just after there is adaptability deflection, and vehicle has finally driven towards the direction B of the guiding of track 122. Before being driven out to circuit switching region, restore raised configuration with the ipsilateral contact roller of track 122, a commutation process terminates.

When determining is track 121, since 121 leads of track are straight, by keeping steering assistance oil cylinder 150 to lock It can pass through；Can also the access section by the ipsilateral contact roller 143 of track 121 in switch zones first fall, wait travel to de- It is risen again from section and realizes that vehicle passes through.

The application scenarios that the present embodiment and relevant drawings are not enumerated are the 4 kinds of steering schemes and 1 spy in the vehicle It realizes, repeats no more under different regime mode.

Electric wheel hub technology can be used in the driving wheel 141 of the present embodiment, it is possible to use wheel motor technology, or in generic card Directive wheel etc. is installed on the basis of the rigid drive axle of vehicle additional to realize.Two sets of front and back running gear assembly can all have driving capability, Can also only wherein it is a set of have driving capability, with regard to current power, transmission technical level and the present invention for it is easy to accomplish, this is non- The key content of invention, the basic technology only made to realize the present invention are introduced, are repeated no more.

The simplification done to the present embodiment and distributing adjustment such as cancel directive wheel 142 and the guiding regulation of vehicle side Mechanism (i.e. contact roller 143, bracket 144 and guiding regulation oil cylinder 146 etc.), is for another example suspended in vehicle frame 130 by sunpender for compartment Lower section repeats no more without prejudice to the principle of the present embodiment and application method.

Second specific embodiment

Fig. 5 illustrates a scene of embodiment utilization.In this embodiment, the running gear of vehicle is distributed in the top of vehicle Portion and bottom, including two sets of guide wheel running gear assemblies 240 and two sets of guiding regulation devices 250, all compositions of running gear All realize that structure is integrated by vehicle frame 230 in part.

The detailed construction and composition of driving device are as shown in Figure 6, Figure 7, and 4 of 240 top of guide wheel running gear assembly lead To wheel 242 by the realization of shaft 243 to the course changing control (whole connected form) of driving wheel 241；Being oriented to regulation device 250 includes The specific function of contact roller 251(directive wheel positions), wheel shaft 252, telescopic arm 253, regulation oil cylinder 254 and wheel shaft lock rationed marketing 255, The composition such as telescopic arm locking element 256, in the case where the actuation of regulation oil cylinder 254 and locking pin 255 and locking element 256 cooperate, wheel Axis 252 and telescopic arm 253 can realize pitching movement and the stretching motion along 230 slideway of vehicle frame respectively.

A set of guiding regulation device can determine an operating status (line direction) of vehicle, with driving wheel 241, directive wheel 242 and contact roller 251 it is corresponding be walking track 211(concave), guide rail 221 and 222, effect of the directive wheel in contact roller It is lower to can be achieved to fit closely guide rail.Similar with the application mode of first embodiment, it is superfluous that the present embodiment still uses guide wheel Remaining design scheme, according to the different conditions of two sets of guiding regulation devices, which can implement four kinds of guiding schemes.

In scene shown in Fig. 5, when normally travel, two tracks are in the same direction at this time along track 222 and 221(for vehicle) determination side It is travelled to A, two sets of guiding regulation devices can be all stowed in carriage body construction at this time；Telescopic arm 253 can also be locked in At maximum extension elongation, 1 ~ 2 contact roller 251 is risen, as shown in figure 9, only rising the ipsilateral contact roller of track 222.

When vehicle advance to road it is Zone switched before, need to judge that vehicle will continue to move on along track 221 or 222. Determination method as in the first embodiment, when determine be that the more former direction A of track 221(is deflected) after, need to adjust, determine track 221 ipsilateral contact rollers 251 are in raised configuration and telescopic arm 253 is in maximum stretching state, 221 opposite side (i.e. track of track 222 is ipsilateral) contact roller 251 be in collapsed state.After vehicle enters circuit switching region, as vehicle advances, guided way Road 221 restores straight (along the direction B) after first there is bending, and wheel shaft 252 and 253 solid lock of telescopic arm are stretched in wheel shaft lock rationed marketing at this time Contracting arm 253 first shrinks to body inner side under the action of regulating and controlling oil cylinder 254 and then stretches out again, and then guarantees commutation process track 4 directive wheels 242 of 221 sides can be bonded completely with track 221.As track 222 restores straight, vehicle completes first power To switching, continued on along direction B, as shown in Figure 10.

The simplification done to the present embodiment and distributing adjustment, such as by the directive wheel 242 of every set guide wheel running gear assembly 240 Quantity be kept to 2 along vehicle traveling direction, for another example will guiding regulation device be integrated on guide wheel running gear assembly 240, Without prejudice to the principle of the present embodiment and application method, repeat no more.

Third specific embodiment

Figure 11 illustrates a scene of embodiment utilization.In this embodiment, the running gear of vehicle is distributed in vehicle Bottom applies bridge steering principle, for the guide wheel running gear assembly 340 that two nested structures are identical, are symmetrically installed.Two sets of assemblies are logical Cross and hingedly realize that structure is integrated with vehicle frame 350, separately have 4 steering assistance oil cylinders 360 for control vehicle riding stability and Vehicle heading is controlled in no guide rail section.Compartment 370 is connected on vehicle frame 350.

The structure type of guide wheel running gear is as shown in figure 13, is carried and is driven with traveling wheel 342 when vehicle driving；Two Directive wheel 345 is arranged in below the middle part of integral axle 341, acts on the traveling side that vehicle is controlled for the guide groove on road To.On road plane, guide wheel 345 has the symmetry relative to vehicle bridge axis, guarantees to pass through circular arc section in vehicle with this When, vehicle bridge axis can pass through the turning center of vehicle.Directive wheel 345 regulates and controls oil cylinder 344 by two guiding and stringer 346 is real Existing working condition (height) switching.Oil cylinder 344 is Multi-stage cylinder, it can be achieved that 3 kinds of different retracted positions, corresponding 2 kinds of rail runnings State and 1 road running state (directive wheel is shunk more than road plane, for short distance to be motor-driven and line adjustment etc.).

The track and highway form of this vehicle are close, are mainly characterized by being provided with guide groove in the middle part of road (visually For the modification of guide rail).By specific structure type, guide groove can be divided into upper layer guide groove 310, transition guide groove 320 and lower layer's guide groove 330, channel widths are slightly larger than guiding wheel diameter, under conditions of guaranteeing directive wheel normal rotation, reduce its width and can be improved and lead The guiding accuracy of slot.
