Specific implementation mode
The present invention relates to a kind of guide wheel assemblies being used to guide vehicle such as single-track vehicle, a kind of this directive wheels of use The bogie of the single-track vehicle of component and a kind of single-track vehicle using this bogie.
Referring 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 be supported 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.The present embodiment turns To frame 16 use six guide wheel assemblies 24, the guide wheel assemblies 24 for make bearing wheels 20 is kept on nose girder 12 between two parties and It is aligned with the holding of nose girder 12.Two lower part guide wheel assemblies 25 also known as stablize wheel assembly, because they, which also have, stablizes single track The effect of the rolling of vehicle 10.However, they are identical as 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 at least two (at this It is six in the case of embodiment is discribed) corresponding directive wheel main shaft 22.Fig. 4 shows such directive wheel main shaft 22, wherein guide wheel assemblies 24 are removed for clarity.It hangs down the both sides of 22 each leisure bogie frame 18 of directive wheel main shaft Directly extend downwardly.The each guide wheel assemblies 24 for being installed to different main shafts 22 are adapted to the wherein side of contact nose girder 12.
It reference is now concurrently made to Fig. 5.Each guide wheel assemblies 24 includes wheel hub 26, directive wheel 28, is mounted on directive wheel 28 On tire 30 and be coaxially rotatably mounted to wheel hub 26 and with 28 coaxillay aligned safety wheel 32 of directive wheel.
Each guide wheel assemblies 24 correspond to wheel hub 26 by it and are rotatably mounted to its correspondence main shaft 22, the wheel hub 26 It is rotated by hub bearing 44 on main shaft 22.There is wheel hub 26 length (axis along longitudinal direction) along wheel hub 26 spaced apart to lead 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.Corresponding aperture in directive wheel 28 can be aligned with stud 40 in a usual manner, so that Nut 42 can be used against the flange 38 of directive wheel installation interface 34 to install securely in directive wheel 28.
Advantageously, directive wheel 28 can be removably mounted near the free terminal 46 of main shaft 22 on wheel hub 26. Free terminal 46 should be understood the end of main shaft 22 not being retained in bogie frame 18.It is damaged in directive wheel 28 or tire 30 In the case of bad, or only in the case where needing replacing worn tire 30, directive wheel 28 is installed to the freely end of main shaft 22 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 replace the very similar mode re-type 30 of automobile tire 28; And directive wheel 28 is reinstalled back on wheel hub 26.Therefore, re-type 30 is more simply and more rapidly.Safety wheel 32 can be in neighbour It closely and in close proximity at main shaft installation interface 47 is mounted 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 in by safe wheel bearing 48 on wheel hub 26 on safety wheel installation interface 36.Peace Full wheel bearing 48 can be any kind of bearing arrangement such as ball bearing, roller bearing, sleeve or only coating is such asCoating.By being installed come safety wheel 32 and by allowing safety wheel 32 only on wheel hub 26 independently of directive wheel 28 It on the spot rotates, has 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 that there are some differential speeds.This differential speed between safety wheel 32 and directive wheel 28 is required, because of safety wheel 32 have radius more smaller than the radius of clean-up of tire 30 and therefore circumference and therefore smaller circumference.In fact, when filling 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, occur in order to prevent with the side of nose girder 12 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 that bend or track switch medium velocity it is higher or in the case where lateral wind is larger), safety wheel 32 is then operable to and takes turns The side of tire 30 while contact beams simultaneously rolls on it, and continues to guide and/or stablize single-track vehicle 10 and/or prevent tire Overload.Due to the circumference of tire 30 keep identical (either inflation or gas leakage) and due to tire when losing heart still It is so rolled on the side of nose girder 12, therefore the rotating speed of tire 30 is less than the rotating speed of safety wheel 32.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 12, safety wheel Both 32 and tire 30 occur non-sliding type with the side of nose girder 12 and contact simultaneously.Advantageously, because safety wheel 32 is rotatable Ground is mounted 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 service life is 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 of tire 30 deteriorates.Cone or curved shape web 50 allow have shorter wheel hub 26, while still crossing tire 30.
The present invention is described relative to preferred embodiment.Specification and attached drawing are intended to help to understand the present invention Rather than it limits the scope of the invention.It will be apparent to those skilled in the art that 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.
