Description
Technical field
The present invention relates to monorail train equipment technology field, more particularly to a kind of adhesive force controllable monorail train and single track
Traffic system.
Background technology
With the globalization of today's society, continuative transport demand is growing day by day, and at the same time, vehicles transport
But increasingly reduce at a same speed (especially in city) in space.It would therefore be highly desirable to develop it is various need not take " individual " friendship
The logical very new-type transportation system of crowded road.
Monorail transit system used in short distance public transport needs directly to share to use path space, and in low cost
Significant advantage is shown with terms of the execution time, this Dominant Facies are especially pronounced for " subway " and " tramcar ".Relative to
For these systems, monorail transit is relatively low to infrastructure requirements, and cost and run time highest can reduce 70%；In addition, institute
Lighter with vehicle weight, structure more simplifies, so as to reduce operating cost and maintenance needs.
The performance of the monorail system in use is quite general now, its energy consumption be higher than rail system, driving force easily by
The influence of arrow gauge and trade shape.Therefore, they are particularly suitable for use in the traffic fortune in urban transportation or 20/30 kilometer radius
It is defeated.If the middle distance transport within 250 kilometers can use monorail transit system, many urban transport problems will be readily solved,
Especially when it is considered that still having the track of several hundred kilometers in the range of the urban district or suburbs of modernization metropolis.Wherein, ground
The operation of iron net network (i.e. subway system) economy is sufficiently complex, and is unfavorable for light rail surface texture safety, because road network is (i.e. public
Road system) there is continuous intersection.Therefore, single track network can overcome some limitations that traditional road is transported well.
Specifically, we analyze the characteristics of highway transportation is relative to railway transportation.For traction abrasion, highway fortune
Wheel coefficient of friction in defeated is larger, therefore traction of the moment of torsion higher than identical weight on railway equipment that road vehicle is transmitted.
Higher torque value can realize higher acceleration and shorter braking distance under given weight condition, can also be on continuous surface
Operation, cost almost with pitch with concrete road surface as it is low, in addition can also preferably adjustment direction change (curve).The opposing party
The coefficient of friction of face, pitch or concrete surface is more than stainless steel, accordingly, it is capable to which it is much greater to consume demand.
Rolling stock realizes traction on rail, and attachment coefficient is far below the traction on rubber.Therefore, it is identical to realize
Performance (accelerate and brake), rolling stock must use " attachment " weight more than the vehicle driven on rubber, therefore, railway
Vehicle is higher in the power and energy consumption needed for startup and boost phase；By contrast, the coefficient of friction between steel and steel is extremely low,
During constant-speed operation, energy ratio wheeled vehicle is much smaller needed for driving.
The producible maximum drawbar pull of Fmax=vehicles, Fmax itself and adhesive force are in functional relation；Weight on P=driving wheels
Amount；δ=coefficient of friction；Speed is no more than in the case of 130 km/h, coefficient of friction of the rubber tyre on dry asphalt surface
Generally 0.5~1.2 (commercial type tire), dry track is usually 0.13~0.33.Fmax=P* δ, above-mentioned Fmax, P, δ are present
Above-mentioned relation formula.
Therefore, rail vehicle is not suitable for " urban district " traffic with the characteristics of frequently accelerating and slow down, but is suited to speed up
Travel at the uniform speed time longer middle distance and long-distance transportation between deceleration.Above-mentioned analysis shows wheeled vehicle is more suitable for short distance
From passenger traffic, especially needing frequently to accelerate and slow down and abrupt slope and " narrow " curved more urban district and suburbs.But comparatively, rail
Road vehicle has higher economy in the less middle and long distance transport of brake and the number of starts.
But traditional monorail track train, quick accelerate and quick deceleration system can not be quickly realized in startup and braking
Dynamic parking, consumed energy is larger when at the uniform velocity does not save；Therefore a kind of energy-conservation and the good list of traction control how to be designed
Rail train is the key solved the problems, such as.

Pressure-bearing surface 201.
Preferably, the pressure-bearing surface 201 of the track is the curved surface on smooth inclined-plane or indent.
It should be noted that it is well known that " transport of rubber tyre traction " has higher adhesive rate, compared with rail fortune
It is defeated it can discharge higher dyad in the case of " attachment " weight identical.This allows for the tire vehicles (in weight phase
With in the case of) higher acceleration can be possessed, and can be stopped in shorter distance.But another aspect tire/
The coefficient of friction of pitch is bigger than the coefficient of friction of steel and steel, therefore required quantity of energy affirmative is at the uniform velocity run under state more
It is high.
In Rail transport, the adhesive rate during adhesive rate is transported than tire is low.Thus want to obtain similar characteristic (
When accelerating and braking) it must just possess bigger " attachment " weight, so Rail transport instrument is just it is necessary to have bigger horsepower,
Consume more energy in operation, similarly, coefficient of friction is very low, thus at the uniform velocity under traveling in but than tire means of transport need
Want less energy.
If we represent maximum drawbar pull with " STmax ", the weight being supported on force x tire is represented with " P ",
Adhesive rate is represented with δ, (for adhesive rate between 1.2 and 0.5, with dry double track is 0.33 between commercial type tire and dry pitch
And between 0.22, when 130 kilometers per hour of scooter).Obtained result is：STmax=P* δ；This result illustrates, wants
Accelerate and identical tractive force obtained when braking, rail vehicle must than the one tire vehicles weigh 2.3 to 3.6
Times.
Therefore rail vehicle is just unsuitable needs the city operations of frequently acceleration and brake, but is especially suitable for
In, long-distance transport, and need between acceleration and brake a longer interval.Therefore tire traffic work can be reasoned out
Tool is more suitable for needing the passenger transport of frequently acceleration and the short distance braked closely, can there is the larger gradient.And Rail transport
It is more economical economical for need not repeatedly brake and restart, without in great slope, for long journey.
So the adhesive force that provides of the present invention controllable monorail train and monorail traffic system, its technical purpose is exactly：
Start and brake during " increase " adhesion weight, and reduce during " RUN " adhesion weight, and then realize startup
Or increase track friction effect Rapid Implementation acceleration or deceleration during braking, track friction effect is reduced when traveling at the uniform speed and saves energy
Consumption.
It should be noted that in embodiments of the present invention, 2 or 4 power are included on the car body of monorail track train
Wheel, is placed in the top of track girder, necessary dyad when effect is release traction, (according to the weight of train and is carried in inflated wheel
Inertia force on tire) 4 or 2 side guide wheels (i.e. guide wheel 101) are further provided with, and it is solid positioned at 2 of lower or 4

The particular technique construction and particular technique effect of each above-mentioned embodiment are done and described in detail below：
In the controllable monorail train structure of adhesive force provided in an embodiment of the present invention, we improve its mechanical part with
And innovatively add its control section；
Wherein, control section is mainly pre-add borne control system；Main body in mechanical part is the support of track train bottom
Car parts, chassis portion of frame part and monorail train etc.；Wherein, bracket portion is mainly by guide wheel 101, hydraulic driving machine
It is structure 102, support body 103, guide wheel installing arm 104, vertical scroll wheel 105, horizontal wheels installing arm 106, horizontal rolling wheel 107, adjustable

The structure compositions such as 403；Above-mentioned chassis portion is arranged between track 200 and car parts, and chassis portion is used to support compartment portion
The weight divided；
Bracket portion is core texture simultaneously；Control section is mainly pre-add borne control system, pre-add borne control system master
Will be to being that the adhesive force for the pressure-bearing surface 201 that the guide wheel 101 in bracket portion is carried in track 200 is adjusted control；It is above-mentioned pre-
The adhesive force that its direct drive 101 of Loading Control System is attached on the pressure-bearing surface 201 of track 200 is adjusted control, i.e., straight
Air pressure drive mechanism (or other drive mechanisms) driving guide wheel 101 was connected, can be led to during " start and brake "
The rubbing action crossed between pre-add borne control system driving increase guide wheel 101 and the pressure-bearing surface 201 of track, and then " increase " attachment
Weight, can be achieved quick accelerate and fast braking；In addition, being subtracted during at the uniform velocity " RUN " by the driving of pre-add borne control system
Rubbing action and then " reduction " adhesion weight between the pressure-bearing surface 201 of few guide wheel 101 and track, can reduce track friction effect
Save a large amount of energy consumptions；
Specifically, guide wheel tire pair can be changed by the preloading of each pair guide wheel 101 according to above-mentioned design bracket 100
The gripping force of track 200.Guide wheel 101 plays a part of stable car body simultaneously.The horizontal rolling wheel 107 of bottom installing has into one
The stabilization of step.Guide wheel 101 can be changed at any time to the inclined plane of track 200 by being equipped with pre-add borne control system for each guide wheel 101

Section can improve or reduce guide wheel 101 to ability is passed under the driving force of track 200, so as to cause the acceleration of (assuming that power is sufficient) vehicle
The increase of power.The preload force of guide wheel 101 can be by the pneumatosphere actuating mechanism controls manipulated by fuzzy logic algorithm.
Because guide wheel 101 applies powerful upward pressure to track 200, downward reaction force is produced, increases guide wheel 101
To the adhesive force of track 200.Tractive force in the case of this holding same friction produced by artificial increased power is more than
The tractive force produced under vehicle own wt, so that vehicle can load more moments of torsion downwards and realize higher acceleration
Value.
The design of track 200 and bracket 100 ultimately limit " texturing " (the non-effective weight) of vehicle weight." texturing " is limited
System is extremely important, because what it was carried is that will not produce a profit and can only produce the load of expense.Vehicle " gross weight " is depended on
Two key elements：Construction weight and required driving force is measured into required weight the need for loading is to keep on vehicle downwards.Ying Jinke
Vehicle " gross weight " can be reduced, because non-effective weight will consume additional energy.Above-mentioned " the hair for being designed to substantially reduce vehicle
Weight ".
Therefore, these above-mentioned inventive embodiments can provide good driving dynamics for vehicle, save energy consumption, and enhancing is transported at a high speed
Stability during row, improves and turns to security, and in the case where not reducing performance ramp angle can be made to lift 18/20%.
Specifically, the change of guide wheel preload force can reduce linear resistance, so as to reduce energy consumption and power loading, simultaneously
Stability of the vehicle under the conditions of bending section or crosswind can also be improved.During vehicle smooth-ride, traction control is by pre-add
Minimum value of the power restriction needed for correct tire gripping force is kept is carried, and compensates crosswind or the tilting moment caused of turning round.Pre-add
The dynamic of load is adjusted to compartment and provides good driving dynamics, it is allowed to which it is carried out with higher speed.Due to the increase of adhesive force
It is not need to rely on the weight of car body, it is possible to mitigate car body weight, and the mitigation of car body weight will significantly reduce energy consumption, together
When can reduce the appearance of resonant frequency.
The mechanism advantage is also embodied in vehicle uphill, downhill and braking.
During climbing, inclination angle makes vehicle reduce the vertical component for rolling surface, and tractive force accordingly reduces；Such a situation
Under, traction control can be pressurizeed by guide wheel to track to increase virtual weight, compensation vertical component loss, and make it recover to realize
With effective power in the maximum needed for the maximum feasible acceleration of functional relation, tyre slip phenomenon is eliminated.Pass through such a side
Method, vehicle can start to walk under the conditions of all slopes, keep starting velocity or acceleration magnitude, therefore, designer is in designed path
When the value of slope that be able to can be reached higher than traditional mass transit road of the set gradient, even there is ice and snow in consideration
Under, it could be used that the higher gradient.
During down hill braking, traction control can be also adjusted vertical component to the numerical value realized needed for braking.
During emergency brake, traction control can realize the maximization of vehicle virtual weight, it is allowed to apply vehicle emergent stopping institute
The maximum drawbar pull needed.
Due to track and bracket be designed to the required power for being enough to ensure that performance is loaded on guide wheel, therefore can
The less light vehicle design of tyre resistance coefficient is realized, while ensuring low energy consumption, economic management can be also realized even if long track.
In addition to it can increase the driving force for traction, also allow to obtain the opposite effect and adjust decelerative force, to reduce system
Dynamic distance, especially in the case where ice and snow causes adhesive force poor.Finally, new-type rail Track desigh adds driving safety
Property, it is prevented effectively from the danger caused due to carelessness.
