Description
Technical field
It is exactly to adapt to country variant rail gauge the present invention relates to a kind of train wheel, can be on axle
The train wheel of axial movement.
Background technology
For quick and low trade cost goods handling to all over the world, it is necessary to the transnational directly transport of train.And show
Some trains go out the gateway of a country, and rail gauge is different between there is country, and train can not directly use, need to unload and be loaded on other country's train
Traveling, wastes a large amount of manpowers, material resources and time.And the general vehicle bridge patent of the different gauges of train, it is by the carrying of wheel and guiding
Function is separated, and makes axle structure complicated.
The content of the invention
In order to avoid it is above-mentioned the occurrence of, the present invention provides a kind of carrying and the indiscrete wheel of guide function, and it leads to
Artificial simple adjustment is crossed, other country's track just train can be directly driven into, save a large amount of manpowers, material resources and time.
The technical solution adopted for the present invention to solve the technical problems is：The interference fit of train wheel and axletree is changed
Coordinate for gap, and in normal operation by wheel alignment on axle.Spacing stud is enclosed on the inside of the side frame spring bearing of shaft end,
It is fixed on axle, stop nut is screwed on spacing stud.Two positioning studs one are left-hand thread, and one is right-hand thread, is enclosed on axletree wheel
Internally, wheel is withstood, positioning stud is relative and axle, only axial movement is not rotated, and location nut is symmetrically screwed in two positioning studs
On, it is corresponding with positioning stud with left-right rotary screw thread.The contour symmetrical oblique angles linking of different gauge rail straight lines, and from small gauge
Rail contact starts to train to fully enter length in big gauge rail, provided with guide groove.When train is driven towards by small gauge rail
During big gauge rail, stop, enter to external-adjuster stop nut to wheel after big gauge rail, just with wheel before rail is become
Withstand, start train and slowly drive towards big gauge rail, wheel prolongs axle and be displaced outwardly in the presence of rail guide groove, until
Train after big gauge rail guide groove completely into stopping, and adjustment location nut is untill positioning stud presses wheel, and train enters
Enter big gauge rail normally travel.When train drives towards small gauge rail by big gauge rail, stopped before rail is become, now car
Wheel is in big gauge rail guide groove.Location nut is adjusted, positioning stud is moved inwardly into wheel into small gauge rail
Afterwards, wheel can be just withstood, starts train and drives towards small gauge rail, wheel prolongs axle and inwardly moved in the presence of rail guide groove
Dynamic, train stops after fully entering small gauge rail, stop nut is adjusted to wheel is pressed, train enters small gauge rail
Normally travel.
The beneficial effects of the invention are as follows rail gauge was different between both having solved country, and train directly drives into problem, solved again
Determined wheel carrying and the not separated problem of guide function, and simple in construction, operation is simple.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.

Embodiment
In Fig. 1, train wheel 3 coordinates with axletree 8 for gap, and wheel 3 can be moved axially on axletree 8.Spacing stud
12 are enclosed on the inside of the spring bearing of 8 shaft end side frame of axle 1, are fixed on holding screw 13 on axle, stop nut 11 is screwed in spacing stud
On 12, locked with clamping screw 2.Positioning stud 4 and 7, one is left-hand thread, and one is right-hand thread, is enclosed on axle 8, the inner side of wheel 3,
Withstand wheel.Positioning stud 4 and 7 is under the limitation of pin 10, relatively with axle 8, and only axial movement is not rotated.6 pairs of location nut
Title is screwed on two positioning studs 4 and 7, corresponding with positioning stud 4 and 7 with left-right rotary screw thread.
In fig. 2, the contour symmetrical oblique angle linking of different gauge rail a and b straight lines, and being opened from small gauge rail a contacts
Begin to train to fully enter length in big gauge rail b, provided with guide groove c.
When train drives towards big gauge rail b by small gauge rail a, stopped before rail is become, unclamp clamping screw 2, outwards
Adjust stop nut 11 to wheel 3 to enter after big gauge rail b, just withstood with wheel 3, then lock clamping screw 2, start
Train slowly drives towards big gauge rail b, at this moment, and wheel 3 prolongs axle 8 and be displaced outwardly in the presence of rail guide groove c, until row
Car unclamps clamping screw 5, adjustment location nut 6 to positioning stud 4 and 7 completely into being stopped after big gauge rail b guide grooves c
Untill pressing closer wheel, then clamping screw 5 is locked, train enters big gauge rail b normally travels.
When train drives towards small gauge rail a by big gauge rail b, stopped before rail is become, now train wheel 3 is big
In gauge rail b guide grooves c.Clamping screw 5 is unclamped, location nut 6 is adjusted, positioning stud 4 and 7 is moved inwardly into wheel
Into after small gauge rail a, wheel can be just withstood, then locks clamping screw 5, starts train and drives towards small gauge rail a, car
Wheel 3 prolongs axle 8 and moved inward, train stops after fully entering small gauge rail a in the presence of rail guide groove c, unclamps lock
Tight bolt 2, stop nut 11 is adjusted to pressing wheel 3, then locks clamping screw 2, and it is normal that train enters small gauge rail a
Traveling.
Stop nut 11 and positioning stud 4 and 7 press wheel to train all the time in operation, reduce wheel and axletree 8 because between
Gap coordinates caused noise and unstable.
