Road beam produces pressure F respectively to two directive wheels of homonymy10And F11, track girder produces respectively to two steady wheels of opposite side
Pressure F12And F13, F10、F11、F12And F13It is not zero, now forms a stress balance system；F10To compartment centre of form origin Z2
Projector distance be X11, F11To compartment centre of form origin Z2Projector distance be X12, F12To compartment centre of form origin Z2Projector distance
For X9, F13To compartment centre of form origin Z2Projector distance be X10, therefore strong balance and equalising torque：
F9=F10+F11-F12-F13
F11×X12+F12×X9=F10×X11+F13×X10
The coaxial directive wheel in left side and right side in front of when by track girder seam crossing will appear from phenomenon of coming to nothing with steady wheel,
Pressure F of the track girder to steady wheel13=0, pressure F of the track girder to directive wheel11=0, above-mentioned stress balance state is broken,
Antitorque moment disappears, torsional moment increase, causes compartment to reverse and rocks.This torsion is rocked until steady wheel and directive wheel and rail
Road beam is contacted again, untill forming new stress balance state.The patent can not solve vehicle torsion proposed by the invention
The problem of rocking excessive, and without reference to the description for being located at other positions to steady wheel.
Chinese Patent Application No. CN103889811A discloses a kind of bogie servicing unit, it is proposed that it is unique stable
Wheel can be located at the optional position between directive wheel, but its bogie structure proposed had both been unable to reach optimal car body stress shape
State, unique steady wheel can equally come to nothing phenomenon in the seam crossing by adjacent orbit beam, it is impossible to solve the present invention and carry
The problem of vehicle rocks excessive caused by the torsion of coming to nothing gone out.
In view of the above-mentioned problems, the larger actual conditions rocked easily occur with reference to Straddle type monorail transportation vehicle, inventor's warp
Analysis is crossed, according to existing theoretical and practical experience, from bogie action principle, is studied, developed, it is final to propose that this is special

Embodiment
This patent action principle explanation
A kind of action principle of Straddle type monorail transportation vehicle bogie is described further below in conjunction with accompanying drawing, herein
Before it should be pointed out that being intended only as demonstration by the embodiment described by accompanying drawing carries out principle explanation, it is impossible to be interpreted as to this hair
Bright limitation.
Demonstration explanation is carried out to the action principle of the bogie based on this patent with reference to Fig. 1~Fig. 4 first.Described
A kind of three axle travelling wheel bogies include bogie main frame 1；Three traveling wheel shafts, including travelling wheel 2a, travelling wheel 2b, traveling
Take turns 2c；With four directive wheels, including directive wheel 3a, directive wheel 3b, directive wheel 3c, directive wheel 3d；With 4 arms of stability, it is including steady
Determine arm 4a, arm of stability 4b, arm of stability 4c, arm of stability 4d, and four steady wheels installed in arm of stability end, including steady wheel
5a, steady wheel 5b, steady wheel 5c and steady wheel 5d.
From a structural point, bogie main frame 1 is as primary structure, and travelling wheel is arranged on bogie main frame 1.Its
In, travelling wheel 2a and travelling wheel 2c bearing side are connected with bogie main frame 1, and travelling wheel 2b bearing both sides are with turning to
Frame main frame 1 is connected.It should be pointed out that arrangement form and the position adjustment of the visual drive device of the specific link position of travelling wheel,
The bearing of travelling wheel unilateral can be connected with bogie main frame 1, can also bilateral connection or both connected modes
Combination, depending on specific turning information summary consider.Directive wheel 3a, directive wheel 3b, directive wheel 3c, directive wheel 3d are separately mounted to turn
On the leading arm stretched out to frame main frame 1 per side end, with vehicle guidance effect.Arm of stability 4a, arm of stability 4b, which are arranged in, to be turned
To the side of frame main frame 1, it is longitudinally arranged along track girder 6, the symmetrical cloth in the centre between directive wheel 3a and directive wheel 3b
Put.Opposite side arm of stability 4c, arm of stability 4d arrangement and arm of stability 4a and arm of stability 4b can be arranged symmetrically, as schemed after the completion of arrangement
Shown in 2~Fig. 4.It is not difficult to find out steady wheel 5a, steady wheel 5b, steady wheel 5c and the steady wheel 5d this four on the arm of stability
Steady wheel is all disposed between directive wheel, is not had with described directive wheel 3a, directive wheel 3b, directive wheel 3c and directive wheel 3d
Coaxially arranged relation.
From stress with functionally for, three axle travelling wheel bogies have steady wheel 5a, steady wheel 5b, steady wheel 5c and steady
This four steady wheels of fixed wheel 5d, the arrangement between steady wheel 5a and steady wheel 5b, between steady wheel 5c and steady wheel 5d is apart from D1
Once come to nothing time t with single steady wheel1It is relevant with Vehicle Speed v, arrange apart from D1It is greater than D2=v × t1, only this
Sample just can guarantee that at least two steady wheels and track girder 6 keep being in close contact, that is, ensure to have at any time at least three
Force, prevents steady wheel comes to nothing from causing vehicle to rock.Meanwhile, between steady wheel 5a and steady wheel 5b, steady wheel 5c and steady wheel
Arrangement between 5d is apart from D1Be less than between homonymy directive wheel 3a and directive wheel 3b, the wheel between directive wheel 3c and directive wheel 3d
The heart is away from D3.Centre-to-centre spacing D between steady wheel 5b and directive wheel 3b5It is greater than vehicle to send out by track girder joint plate in directive wheel
Raw t this period that comes to nothing2The distance D inside passed by4, and the centre-to-centre spacing D between steady wheel 5b and directive wheel 3b5It is greater than train
In steady wheel by track girder joint plate and t this period that comes to nothing1The distance D inside passed by2.Directive wheel and steady wheel arrangement
The specific reason that spacing is chosen is as follows：
Train is D in the distance that steady wheel is passed by by joint plate in this period of coming to nothing2, monorail train traveling
Maximal rate be v, take v=80km/h, train bogie steady wheel 5b to come to nothing the time for t1, take t1=0.01s, then D2=v ×
t1=80/3.6 × 0.01=0.22m, train bogie directive wheel 3b come to nothing the time for t2, take t2=0.01s, then D4=v × t2
=80/3.6 × 0.01=0.22m；The spacing at steady wheel 5a and steady wheel 5b centers is D1, steady wheel 5c and steady wheel 5d centers
Spacing be D1, when the train that is smaller than at the steady wheel center of bogie side two takes off in steady wheel by joint plate
The distance passed by empty this period, i.e. D1＜ D2When, the steady wheel of bogie side two will come to nothing phenomenon simultaneously, make
Rocked into compartment generation is larger, therefore D should be met1＞ D2.Similarly, the centre-to-centre spacing D between steady wheel 5b and directive wheel 3b5It is less than
Vehicle is in directive wheel by track girder joint plate and t this period that comes to nothing2The distance D inside passed by4When, steady wheel is with being oriented to
Wheel is coaxial or is within close proximity, it is impossible to forms torsion of the effective antitorque moment to resist vehicle and rocks.Passing through track girder seam
The steady wheel in left side and right side in front of during place and directive wheel will appear from the phenomenon while coming to nothing, and track girder is to the steady wheel that comes to nothing
Pressure with directive wheel is 0, and stress balance state is broken, and antitorque moment disappears, torsional moment increase, causes compartment to reverse rolling
It is dynamic.This torsion is rocked until steady wheel is contacted again with track girder, untill forming new stress balance state, therefore should be met
D5＞ D4, and D5＞ D2。
As shown in figure 25, during normal vehicle operation, lateral load F0Act on compartment, track girder is to bearing lateral load
F5The directive wheel 3c and directive wheel 3d of homonymy produce pressure F respectively1And F2, steady wheel 5a and steady wheel of the track girder 6 to opposite side
5b produces pressure F3And F4, F1、F2、F3And F4It is not zero；Now form a stress balance system, lateral load F0To compartment
Centre of form origin Z0Projector distance be X1, F1To compartment centre of form origin Z0Projector distance be X2, F2To compartment centre of form origin Z0's
Projector distance is X3, F3To compartment centre of form origin Z0Projector distance be X4, F4To compartment centre of form origin Z0Projector distance be X5,
Therefore strong balance and equalising torque：
F0=F1+F2-F3-F4
F0×X1=F3×X4+F4×X5-F1×X2-F2×X3
When steady wheel 5b and track girder 6 come to nothing, pressure F of the track girder 6 to steady wheel 5b4=0, above-mentioned stress balance shape
It is due to pressure F of the track girder 6 to steady wheel 5a though state changes3≠ 0, the also presence of drag can remain new and put down
Weighing apparatus, will not cause compartment to come to nothing and rock.Until steady wheel 5b is contacted again with track girder 6, recover original stress balance shape
State.Above-mentioned stress balance state is not broken in the process, that is, the presence for having multiple antitorque arm of forces, compartment will not be caused to produce
Raw come to nothing is rocked.
Similarly, when bogie has a steady wheel to come to nothing per side, another steady wheel that can all have homonymy has drag,
The stress of bogie is set to maintain poised state together with two directive wheels of opposite side.Therefore, above-mentioned stress balance state can be protected
Hold, i.e., still have drag in bogie force balance system, compartment will not be caused to produce larger coming to nothing and rocked.
When directive wheel 3d and track girder 6 come to nothing, pressure F of the track girder 6 to directive wheel 3d2=0, above-mentioned stress balance shape
It is due to pressure F of the track girder 6 to steady wheel 5a and steady wheel 5b though state changes3≠ 0, F4≠ 0, also directive wheel 3c
Pressure F1≠ 0, three impetus are formed, new balance is maintained, compartment will not be caused to come to nothing and rocked.Until directive wheel 3d and rail
On road beam 6 is contacted again, recover original stress balance state.Above-mentioned stress balance state is not broken in the process,
There are at least three impetus to produce antitorque moment, form the beaer of a balance, compartment generation will not be caused to come to nothing and rocked.
Analyzed more than, when the quantity >=2 of the arm of stability, that is, Fig. 1~figure arranged in multiple arms of stability, respective figure
24, at least three impetus produce antitorque moment at any time when Straddle type monorail transportation vehicle is run, and form a balance
Beaer, then Straddle type monorail transportation vehicle will not produce larger coming to nothing and rock.Above-mentioned force analysis is found, upper
In the balance expression for stating power and torque, traveling wheel shaft weight, i.e. compartment are not produced to come to nothing and rocked and traveling wheel shaft weight and axle
