Embodiment
This directive wheel is used the present invention relates to a kind of guide wheel assemblies, one kind for guiding vehicle such as single-track vehicle
The bogie of the single-track vehicle of component and a kind of single-track vehicle using this bogie.
With reference now to Fig. 1.Single-track vehicle 10 is placed on nose girder 12.Single-track vehicle 10 includes chassis 14 and two bogies
16.Bogie 16 is connected to chassis 14 to support on nose girder 12 and guide single-track vehicle in its forward terminal and rear end
10。
It reference is now concurrently made to Fig. 2 and Fig. 3.Each bogie 16 includes bogie frame 18, bearing wheels 20 and at least two
Guide wheel assemblies 24.Bearing wheels 20 support single-track vehicle 10 by bogie frame 18 on nose girder 12.Turn of the present embodiment
To frame 16 using six guide wheel assemblies 24, the guide wheel assemblies 24 be used to making bearing wheels 20 is kept on nose girder 12 between two parties and
Keep being aligned with nose girder 12.The also known as stable wheel assembly of two bottom guide wheel assemblies 25, because they, which also have, stablizes single track
The effect of the rolling of vehicle 10.However, they are identical with other guide wheel assemblies 24 in structure.
It reference is now concurrently made to Fig. 4.In order to position each guide wheel assemblies 24, bogie 16 is equipped with least two (at this
Embodiment is six in the case of describing) corresponding directive wheel main shaft 22.Fig. 4 shows such directive wheel main shaft
22, removed wherein being directed to wheel assembly 24 for clarity.Hang down the both sides of each comfortable bogie frame 18 of directive wheel main shaft 22
Directly extend downwardly.The each guide wheel assemblies 24 for being installed to different main 22 are adapted to contact the wherein side of nose girder 12.
It reference is now concurrently made to Fig. 5.Each guide wheel assemblies 24 includes wheel hub 26, directive wheel 28, installed in directive wheel 28
On tire 30 and be coaxially rotatably mounted to wheel hub 26 and with the coaxillay aligned safety wheel of directive wheel 28 32.
Each guide wheel assemblies 24 are rotatably mounted to its correspondence main shaft 22, the wheel hub 26 by its correspondence wheel hub 26
Rotated on main shaft 22 by hub bearing 44.Wheel hub 26, which has along the length (along longitudinal axis) of wheel hub 26, spaced apart leads
To wheel installation interface 34 and safety wheel installation interface 36.Directive wheel installation interface 34 can be that conventional wheel installation interface such as may be used
The flange 38 of press-fitted stud 40 can be used.Respective aperture in directive wheel 28 can be aligned with stud 40 in a usual manner, to cause
Directive wheel 28 can be used nut 42 against the flange 38 of directive wheel installation interface 34 to install securely.
Advantageously, directive wheel 28 can be removably mounted on wheel hub 36 near the free terminal 46 of main shaft 22.
Free terminal 46 should be understood the end not being retained in bogie frame 18 of main shaft 22.Damaged in directive wheel 28 or tire 30
In the case of bad, or only in the case where needing to change worn tire 30, the freely end that wheel 28 is installed to main shaft 22 is directed to
End 46 nearby allows easily to dismantle directive wheel 28, without removing safety wheel 32 from wheel hub 26.Therefore, facilitate feasible
It is:Directive wheel 28 and its tire are removed from wheel hub 26;With with changing the very similar mode re-type 30 of automobile tire 28;
And be directed to wheel and 28 reinstall back on wheel hub 26.Therefore, re-type 30 is more simply and more rapidly.Safety wheel 32 can be in neighbour
Closely and in close proximity at main shaft installation interface 47 it is arranged on wheel hub 26, at the main shaft installation interface 47, main shaft 22 is pacified
It is attached to bogie frame.
Safety wheel 32 is rotatably installed on wheel hub 26 on safety wheel installation interface 36 by safe wheel bearing 48.Peace
Full wheel bearing 48 can be any kind of bearing arrangement such as ball bearing, roller bearing, sleeve or be only coating such asCoating.By independently of directive wheel 28 install come safety wheel 32 and by allow safety wheel 32 on wheel hub 26 solely
On the spot rotate, have between wheel hub 26 and safety wheel 32 and therefore between safety wheel 32 and the directive wheel 28 rotated with wheel hub 26
It may allow the presence of some differential speed.This differential speed between safety wheel 32 and directive wheel 28 is required, because safety wheel
32 have the radius of clean-up and the therefore smaller radius of circumference and therefore smaller circumference than tire 30.Filled in fact, working as
When dividing inflation but no-load, tire 30 has tire radius and tire circumference.When fully aerated and when carrying, tire has than it
The smaller effective radius of clean-up of no-load radius.Therefore, in order to prevent from the side of nose girder 16 occurring when single-track vehicle 10 is operated
Improper contact, safety wheel 32 must have the working diameter less diameter than tire 30.
Advantageously, if tire 30 loses heart or gas leakage, or if abnormal big load fully compressed tires 30 are (such as
In the case where bend or track switch medium velocity are higher or in the case where lateral wind is larger), safety wheel 32 is then operable to and taken turns
Tire 30 side of contact beams and is rolled thereon simultaneously, and is continued to guide and/or stable single-track vehicle 10 and/or prevented tire
Overload.Due to the circumference of tire 30 keep identical (either inflation or gas leakage) and due to tire when discouraged also still
So rolled on the side of nose girder 16, therefore rotating speed of the rotating speed less than safety wheel 32 of tire 30.Safety wheel 32 and tire 30 it
Between this differential speed therefore allow when tire 30 loses heart or gas leakage and safety wheel 32 contact the side of nose girder 16, safety wheel
Both 32 and tire 30 occur non-sliding type with the side of nose girder 16 and contacted simultaneously.Advantageously, because safety wheel 32 is rotatable
Ground is arranged on wheel hub 26 (wheel hub 26 itself rotates on the hub bearing 44 on main shaft 22), and safe wheel bearing 48 is never
Big rotating speed is obtained, but is only rotated with the differential speed between tire 30 and safety wheel 32.This low differential speed allows to make
With relatively inexpensive bearing, such as plane bearing, and advantageously, the longer life-span can be allowed.
Safety wheel can have web 50, the web 50 can be it is flat, as in Fig. 4 draw for cone or have
There is curve shape.In any case, it is preferred that web 50 crosses the shape of flat 30 to prevent friction pulley tire and make
The side wall deterioration of tire 30.Cone or shaped form web 50 allow have shorter wheel hub 26, while still crossing tire 30.
The present invention is described relative to preferred embodiment.Specification and accompanying drawing are intended to help and understand the present invention
Rather than limitation the scope of the present invention.Those skilled in the art will be apparent that, do not departing from as described herein
The scope of the present invention in the case of, can to the present invention various modification can be adapted, and it is such modification be intended to be contained by this specification
Lid.The present invention is limited by following claims.
