Description
Technical field
The invention belongs to rail vehicle wheelset fitting with Auxiliary support positioner field and in particular to a kind of light rail motor-car
Wheelset fitting is with supporting positioning tool.
Background technology
As shown in figure 1, railway vehicle wheel to generally include axletree 1 and with axletree 1 coaxially be connected two wheels 2, system
Moving plate 3, gear-box 4 and planetary plate and its subsidiary body 5, during above-mentioned routine wheel set maintenance, its brake disc 3 and planetary plate and its attached
Belong to mechanism 5 radially directly to unload from axletree 1 respectively or re-assembly, so that wheel only retains the car shown in Fig. 2 to upper
Axle 1, wheel 2 and gear-box 4, become one kind partly move back unload wheel to structure.Then, aforesaid partly move back unload wheel structure just can be utilized
Axle support 6 and wheel, to forcing press co-axially align, carry out moving back to the wheel 2 on axletree 1 and unload or press-fit.As shown in figure 3, it is existing
Axle support 6 includes base 6-1 and two axletree V-shaped block bearing 6-2, and the axial width of its axletree V-shaped block bearing 6-2 is larger,
The height of two axletree V-shaped block bearing 6-2 is identical and spacing of both it is 1.5 meters of fixed value.As shown in figure 4, when using,
One of axletree V-shaped block bearing 6-2 is supported in axletree section 1-1 that original brake disc 3 is located, another one axletree V-shaped block
Bearing 6-2 is supported in axletree section 1-2 that original planetary plate and its subsidiary body 5 are located.
However, as shown in Figure 5 to Figure 6, to being that a kind of more special new wheel of structure is right, it makes Changchun Light Rail motor car wheel
Moving plate 3 and planetary plate and its subsidiary body 5 all cannot radially directly unload from axletree 1, thus causing this wheel to cannot be formed
Partly the moving back of axletree 1, wheel 2 and gear-box 4 that only remain with shown in Fig. 2 unloads wheel to structure.Therefore, it is limited by Changchun Light Rail to move
Wheel limits to upper brake disc 3 and the structure such as planetary plate and its subsidiary body 5, and existing axle support 6 cannot be light to Changchun
To being supported and position, this further results in Changchun Light Rail motor car wheel to cannot be with wheel to forcing press co-axially align to rail motor car wheel
Unload to assembling or moving back with entering road wheel.
Content of the invention
Unload wheel to structure in order to solve existing special Changchun Light Rail motor car wheel to being formed partly to move back, remain with thereon
Brake disc and planetary plate and its subsidiary body interfere with each other respectively at existing axle support, thus causing this Changchun Light Rail motor-car
Wheel to cannot take a seat with existing axle support on, and then make using wheel to forcing press to Changchun Light Rail motor car wheel to implement with
Axle aligns and enters road wheel and to assembling or moves back the technical problem that the operation scheme unloading cannot be implemented, and the present invention provides a kind of light rail motor-car
Wheelset fitting is with supporting positioning tool.
The technical scheme that present invention solution technical problem is taken is as follows:
With supporting positioning tool, it includes traveling support, two the first gripper shoes, two narrow axles to light rail motor-car wheelset fitting
Section detent mechanism, the second gripper shoe and two gear-box support bases, the lower surface of the second gripper shoe and two the first gripper shoes is equal
It is fixed on the top of traveling support, two the first gripper shoes are located at the left and right two ends of the second gripper shoe respectively；Two narrow shaft parts are fixed
Position mechanism is respectively fixedly connected with corresponding first gripper shoe；Two gear-box support bases are respectively positioned on a left side for the second gripper shoe
Side, both it, the long side axis with respect to the second gripper shoe is symmetrical.
Narrow axis section detent mechanism includes convex bearing, v font groove location-plate and bending pressing plate, and described v word groove is fixed
The lower end of position plate and convex bearing are connected；Bending pressing plate and v font groove location-plate surround one polygon axle sleeve of formation jointly,
With the end axle of v font groove location-plate even, the other end both it passes through clip or rope binding is connected for one end of bending pressing plate.
The spacing of described two narrow shaft part detent mechanisms is more than the lateral wall to brake disc for the wheel to planetary plate and its attached machine
The distance between lateral wall of structure, the axial width of polygon axle sleeve is less than the inner side of brake disc lateral wall wheel adjacent thereto
Spacing d between wall1, and the axial width of polygon axle sleeve is adjacent with it again smaller than the lateral wall of planetary plate and its subsidiary body
Spacing d between the medial wall of near wheel2.
The height of described two narrow shaft part detent mechanisms can also be different, but the inscribe of respective polygon axle sleeve both it
Circle is highly gone up in same axis.
Described gear-box support base includes support plate, screw mandrel and screw pedestal, and screw mandrel is connected with screw base thread and is total to
Similar shape becomes leading screw elevating mechanism；Support plate is coaxially fixed on the upper end of screw mandrel.
The invention has the beneficial effects as follows: this light rail motor-car wheelset fitting is with supporting left and right two polygons of positioning tool
Axle sleeve can be respectively fitted over and be exposed to two wheels each on a bit of axletree at rear, the common support both it and positioning energy
Enough make rotary shaft and the plane-parallel of axletree.By two gear-box support bases are all supported in Changchun Light Rail motor car wheel to tooth
The lower surface holding level of gear-box on the lower surface of roller box, can be made, and enable wheel to forcing press and this special type
Wheel to realize coaxially connected and pressure operation.
In addition this light rail motor-car wheelset fitting supports positioning tool also to have simple and practical, easy to operate, cost
Cheap, it is easy to the advantages of popularize.

End axle even, the other end both it passes through clip or rope binding is connected.
The spacing that two narrow shaft parts position structure 7-3 is more than the outer of the lateral wall of brake disc 3 to planetary plate and its subsidiary body 5
The distance between side wall, the axial width of polygon axle sleeve 7-3-4 is less than the interior of brake disc 3 lateral wall wheel 2 adjacent thereto
Spacing d between the wall of side1, and the axial width of polygon axle sleeve 7-3-4 is again smaller than the outside of planetary plate and its subsidiary body 5
Spacing d between the medial wall of wall wheel adjacent thereto 22.
The height of two narrow shaft part positioning structure 7-3 can also be different, but respective polygon axle sleeve 7-3-4's both it is interior
The circle of contact is highly gone up in same axis, to tackle spacing d1Value is too small, and corresponding polygon axle sleeve 7-3-4 cannot be directly clamped among
On axletree 1, and need the situation being directly clamped among in the minimum outer diameter of corresponding brake disc 3.
Gear-box support base 7-5 includes support plate 7-5-1, screw mandrel 7-5-2 and screw pedestal 7-5-3, screw mandrel 7-5-2 and silk
Female pedestal 7-5-3 is threaded and is collectively forming screw-threaded shaft elevator structure.Support plate 7-5-1 is coaxially fixed on the upper of screw mandrel 7-5-2
End.
As shown in Figure 10 to Figure 11, when the light rail motor-car wheelset fitting of the concrete application present invention is with supporting positioning tool, will
Left and right two polygon axle sleeve 7-3-4 are respectively fitted on a bit of axletree 1 being exposed to the respective rear of two wheels 2, both it
Jointly support and position axletree 1 and make rotary shaft and the plane-parallel of axletree 1.Then again two gear-box support base 7-5
All support on the lower surface to gear-box 4 for the Changchun Light Rail motor car wheel, and by adjusting two gear-box support base 7-5's respectively
Thick stick elevating mechanism height, the end face making two support plates 7-5-1 is all in same level, you can complete to Changchun Light Rail motor-car
Wheel to axis horizontal support and position, and enable take turns coaxially connected to realizing with the wheel of this special type to forcing press
With pressure operation.
