Description
Technical field
The present invention relates to the railway traffic equipment of railway class and the fields of operation, more particularly to the axletree equipment of train.
Background technology
The snakelike vibrations of train are also known as serpentine curve movement abbreviation serpentine locomotion, are train operations in railroad track straight line
The self-discipline horizontal cross that section is occurred by wheel tread shakes and causes, and the more fast snakelike vibrations of speed are more violent, face more than snakelike
Accident will occur for boundary's speed.The present invention proposes a kind of decrease for the goods train and light rail train of the unpowered device of bogie
Snakelike vibrations scheme.
The existing snakelike vibrating method of inhibition is that the inclined-plane hook of optimization wheel tread is matched, but has arrived the limit；Other main methods
It is dual anti-snakelike damper, but this method is only controlled bogie, affects indirectly vehicle because being static mechanical mode
Wheel, is not controlled serpentine locomotion occurring source, so effect is limited, when train high-speed cruising, snakelike shake still is sent out
It is raw.The present invention recognizes that serpentine locomotion is a kind of dynamic phenomenon from new viewpoint, and serpentine locomotion is also zero when speed is zero, snakelike fortune
Dynamic increase with speed and increase, therefore, the present invention builds a kind of new Dynamic Theory to design a kind of inhibition based on dynamic
Ability synchronizes the solution of variation with serpentine locomotion.
Although the snakelike vibrations occurring source of train is wheel tread, because being rigidly fixed with it, connect is entire wheel
Axis is as shown in Figure 1, snakelike seismism shows entire axletree, so the present invention is using axletree as occurring source, to inhibit
The serpentine locomotion of axletree, which reaches, inhibits the snakelike vibrations of train.
Factor that there are mainly three types of the main influence serpentine locomotion powers of analysis：Construction, the train running speed of wheel tread
With axletree momentum direction；Wherein the third momentum factor is not realized or is ignored so far.
When train is under the specified conditions that railroad track line interval is run, the kinetic energy that axletree has can resist its state
Variation, that is, resist the change of the size and Orientation of its momentum, and the size of momentum represents the size of the ability of its resistance state variation；
Axletree is influenced by two kinds of momentum, and one is the movement momentum of rectilinear direction, another kind is the movement momentum of oblique line directions.Tiltedly
The generation source of line movement momentum be when transverse vibration forces put aside increase and wheel occurs move lateral out when, because of left and right wheels inclined-plane
The circumference of contact in orbit is different and makes the speed of left and right wheels that difference occur, keep axletree sideling preceding and then oblique line is presented
Move momentum；The mechanical periodicity of diagonal movement shows as serpentine curve movement, as shown in Figure 2.So the conjunction of both momentum is dynamic
The direction of amount determines that the direction of advance of axletree, the mechanical periodicity of the ratio of both momentum determine the serpentine locomotion shape of axletree
State.Diagonal movement momentum is also known as curvilinear motion momentum.It follows that changing the ratio of both momentum, thus it is possible to vary wheel
The axis direction of motion；The ratio of curvilinear motion momentum can be reduced by increasing linear motion momentum, weaken serpentine locomotion state.Namely
It is to increase linear motion momentum to inhibit the variation of the axletree direction of motion, inhibits snakelike vibrations.
Based on principles above, this programme premised on not changing the basic function of axletree, with change axletree momentum and
The size and Orientation of gravity to reduce the fluctuation of the axletree direction of motion and reduces wheel transverse direction external shift quantity for main implementation means,
Inhibit axletree serpentine locomotion to reach.
Invention content
The present invention provides a kind of axletree inhibiting the snakelike vibrations of train, it is characterised in that：It is arranged on the axletree
It is fixed with flywheel, the flywheel is the homogeneous rigid body of regular shape, and the weight of the flywheel is more than the weight of axletree, described to fly
Wheel is to be located at two wheels（1）Between and with wheel axis of spindle（5）Keep symmetrical, described includes symmetrically positional symmetry, shape
Shape is symmetrical, weight is symmetrical.Axletree with the technical characteristic includes：Flywheel on axletree is the width of expanded letter single flywheel 6
The wheeled axletree of body solo flight constructs, and the flywheel on axletree is the wheeled axletree construction of round trip flight of free wheels 8, is flown on axletree
Wheel is that the holoaxial flywheel-type axletree of holoaxial flywheel 9 constructs, and the flywheel on axletree is that the wheel of wheel extension holoaxial flywheel 10 hangs holoaxial
Flywheel-type axletree constructs, and the flywheel on axletree is that the wheel rim flywheel-type axletree of wheel rim flywheel 11 constructs, on axletree
Flywheel is the integrated wheel formula axletree construction of integrated wheel 12.
Beneficial effects of the present invention are as follows.
1. momentum inhibition：Quantitative expression mode as shown in Figure 9 is transported when doubling and increasing by two times of flywheel straight lines
When dynamic momentum, the total amount increase of the momentum of linear motion is（P2+2*P3）＞（P2+P3）＞（P2）So that linear motion is dynamic
The conjunction momentum increase of amount and diagonal movement momentum is P6 ＞ P5 ＞ P4, and the ratio of the diagonal movement momentum in the conjunction momentum reduces,
The result is that it is θ ＜ β ＜ α to close the direction of momentum and the angle reduction of rectilinear direction, that is, the deflection angle for closing momentum reduces, the result is that
Serpentine locomotion deflection angle reduces, and serpentine locomotion weakens.Fig. 9 also shows that the bigger linear motion conjunction momentum of flywheel weight is bigger, directly
Line movement prime move is bigger, inhibits serpentine locomotion effect more notable.
2. dynamic effect：Linear motion momentum is accelerated and increased characteristic is applied to inhibit serpentine locomotion with speed
Ability changes with serpentine locomotion power and synchronizes variation, shows as the dynamic effect of rejection ability.
3. gravity stablizing effect：As shown in Figure 10, the oblique tread of wheel generates sliding force F2, the side of sliding force F2 in orbit
To the inside for being directed toward rail, the angle γ of sliding force F2 and transverse vibration forces F3 is more than 90 °；Axletree gravity F1 and flywheel gravity
The direction of F4 is also all directed on the inside of rail, and flywheel gravity F4 increases sliding force.When transverse vibration forces F3 savings increases and lures
When wheel of dispatching a car moves lateral out, it can be resisted by wheel sliding force F2, and flywheel gravity F4 is just being the increase in this resistance.Again
There are the sliding force F2 of left and right wheels and track that a cleat shape is collectively formed, and the flywheel gravity F4 being pressed on axletree can increase
Strong chock stabilizes effect, can resist transverse vibration forces F3, reduces wheel transverse direction external shift quantity and reaches inhibition serpentine locomotion.
4. advantage dominant effect：Because the flywheel weight that the present invention designs is more than axletree weight, increased straight line
Kinetic momentum is more than axletree momentum, and increased gravity is more than axletree gravity, and can play advantage leading role.
5. bend speedup effect：In bend, train needs are pushed the speed to increase the wheel that centrifugal force will increase weight
It is thrown outside axis, this is also beneficial to train high speed and passes through bend.
6. resistance to vertical vibrating effect：The gravity of flywheel on axletree is conducive to resist vibration force perpendicular to the ground, makes
It must walk more stable.
The resultant effect of said effect makes the present invention can realize to inhibit axletree serpentine locomotion and reach and inhibit train snake
Shape vibrations purpose, can improve train straight line and bend operation limitation velocity.
The suppressing method of the present invention is a kind of new method, and the essential distinction and major advance between existing method are：
1. control mode is different：Existing method is mechanical control method, and this method is restricted based on the mechanics of momentum and gravity
Mode；
2. control model is different：Existing method is fixed mode, and this method is dynamic mode；
3. control object is different：Existing method is control bogie, and this method is directly controlled to occurring source axletree；
4. control ability is different：Existing method control ability is constant, and the variation synchronous with serpentine locomotion of this method control ability.
Further more, usually concept thinks that flywheel is a kind of mechanical device for storing rotation function in rotary motion, use
Flywheel rotation function controls the fluctuation of rotating speed, and the present invention is to resist momentum direction with the straight ahead motion energy of flywheel to become
Change to control the fluctuation of direction of advance, the two has the difference of matter, but assigns flywheel new function.
The craftsmenship of the present invention is the momentum for flywheel being installed on serpentine locomotion occurring source, and it is utilized to generate and gravity
Dual implantation restricts the direction change of itself.Cost effectiveness is extremely low, and does not conflict with existing method, can be used in combination.
