Add stabilization, braking, the acceleration of train are also more efficient, powerful；Meanwhile also guarantee is provided for train speed raising；Particularly in sleet sky
Gas, remains accumulated snow or ponding on rail, the moisture film of formation declines the adhesion for causing rail；When using the present invention, inhale
Attached hole is close and rolls after rail, aspirates the moisture film on rail by suction function, destroys, effectively increases sticking together for rail
Coefficient, ensures that wheel is in close contact with rail, so as to effectively improve the adhesion of wheel and rail；The moisture film of suction is from deflector hole
Middle discharge.
To sum up, the present invention can effectively improve train adhesion, particularly in sleety weather, can weaken moisture film to wheel
Influence, stabilization for train, safety traffic provide guarantee.
Preferably, the adsorption hole radially extending along load-carrying ring；In order to form stronger negative pressure in adsorption hole,
And then absorption dynamics is improved, strengthen the adhesion of wheel and rail.
Preferably, between two adjacent guide holes, the direction that large aperture is directed toward from small-bore is different；The structure causes phase
Airflow direction in adjacent deflector hole is on the contrary, prevent the both sides of loading plate from producing excessive pressure differential, and then ensure loading plate both sides
Stress equalization, extends the service life of loading plate.
Preferably, being provided with wind shield in the monosymmetric of the loading plate, wind shield is parallel with loading plate；It is described
It is slidably connected between wind shield, drive shaft by slip ring, rail structure；Guide vane is provided with the loading plate, it is described to lead
Wind piece is wedge shaped, and wedge shaped tip is towards drive shaft；
Wind shield can block the gas in deflector hole to circulate；On the train run at high speed, guide vane drawn by high-speed flow,
Blow and move backward, drive wind shield to be moved to the rear of wheel, and then stop the deflector hole gas circulation at wheel rear, so that
The suction-operated of wheel back lower place adsorption hole is eliminated, and then weakens resistance of the adsorption hole to wheel, the speed of wheel is effectively ensured.
Brief description of the drawings
Fig. 1 is the positive structure diagram of this bullet train wheel one embodiment.
Fig. 2 is the cross section structure schematic diagram of embodiment illustrated in fig. 1.
Embodiment
Embodiment：
In the embodiment shown in Fig. 1, Fig. 2, this bullet train wheel includes rotating disc and drive shaft 1, and rotating disc is coaxially disposed
At the both ends of drive shaft 1；
The rotating disc includes loading plate 2 and the load-carrying ring 3 being looped around outside loading plate 2, loading plate 2 and the one of load-carrying ring 3
Shaping；The width of load-carrying ring 3 is more than the thickness of loading plate 2；It is respectively arranged with the end face of 3 both sides of load-carrying ring and radially prolongs
The flange stretched；
Through the deflector hole 4 vertical with loading plate 2 is offered on the loading plate 2, the aperture at 4 both ends of deflector hole is not
Together；Adjacent guide hole 4 is different in the aperture of 2 the same side of loading plate；Adsorption hole 5, the adsorption hole 5 are offered on load-carrying ring 3
In load-carrying ring 3 with extending in loading plate 2 and being connected with the deflector hole 4；The radially extending along load-carrying ring 3 of adsorption hole 5；Lead
Discharge orifice 4,5 rotational symmetry of adsorption hole are distributed on rotating disc, and deflector hole 4 matches and connect one by one with adsorption hole 5；In the carrying
The monosymmetric of plate 2 is provided with wind shield 6, and wind shield 6 is parallel with loading plate 2；Pass through between the wind shield 6, drive shaft 1
Slip ring, rail structure are slidably connected；Guide vane 7 is provided with the loading plate 2, the guide vane 7 is wedge shaped, wedge shaped tip
Towards drive shaft 1.
When train is run at high speed, wheel high-speed rotation, the both sides of loading plate 2 produce larger wind speed；Due to 4 liang of deflector hole
The aperture of side is different, therefore the wind pressure that 4 both sides of deflector hole produce is different, and then produces what direction was fixed in 4 axial direction of deflector hole
High-speed flow, the high-speed flow flow to low-pressure area from higher-pressure region；According to hydrodynamics, the high-speed flow in deflector hole 4 can cause
Deflector hole 4 and the junction of adsorption hole 5 produce low pressure, promote the inward-facing adsorbed gas of outer shroud of adsorption hole 5 from load-carrying ring 3, from
And 5 surrounding of adsorption hole is promoted to form negative pressuren zone；
When train is run at high speed, adsorption hole 5 is periodically rolled on rail, adsorption hole 5 produce negative pressure will load-carrying ring 3 with
The suction-combining force is produced between rail, so as to strengthen the adhesion between rail and wheel, with the lifting of adhesion, train driving will
More stablize, braking, the acceleration of train are also more efficient, powerful；Meanwhile also guarantee is provided for train speed raising；Particularly in sleet
Weather, remains accumulated snow or ponding on rail, the moisture film of formation declines the adhesion for causing rail；When using the present invention,
Adsorption hole 5 is close and rolls after rail, aspirates the moisture film on rail by suction function, destroys, effectively increases rail
Adhesion coefficient, ensures that wheel is in close contact with rail, so as to effectively improve the adhesion of wheel and rail；The moisture film of suction is from leading
Discharged in discharge orifice 4.
In the present embodiment, on the train run at high speed, guide vane 7 is drawn by high-speed flow, blows and moves backward,
Wind shield 6 is driven the rear for being moved to wheel, and then stops 4 gas of the deflector hole circulation at wheel rear, with rear water conservancy diversion
Air-flow in hole 4 is blocked, and corresponding adsorption hole 5 will lose negative pressure, and suction-operated eliminates therewith；Inhaled so as to effectively weaken
The speed of wheel is effectively ensured to the resistance of wheel in attached hole 5；In addition, in the present embodiment, due between two adjacent guide holes 4,
The direction difference of large aperture is directed toward from small-bore, i.e., the size arragement direction in 4 both ends aperture of adjacent guide hole is on the contrary, cause water conservancy diversion
The high low pressures of 4 both sides of hole is different, and then causes the airflow direction in adjacent guide hole 4 on the contrary, therefore, two neighboring deflector hole
Circulating current will be formed between 4；The structure can prevent the both sides of loading plate 2 from producing excessive pressure differential, and then ensure loading plate 2
Both sides stress equalization, extends the service life of loading plate 2.
To sum up, the present invention can effectively improve train adhesion, particularly in sleety weather, can weaken moisture film to wheel
Influence, stabilization for train, safety traffic provide guarantee.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on, should all be included in the protection scope of the present invention.
