To be assembled simultaneously, one end can also be first assembled, the other end is then assembled again, bolster 3 is being loaded to the frame mouth of side frame 7
Afterwards, the position of bolster 3 and side frame 7 should keep being relatively fixed, in order to install miscellaneous part.
If it can be seen that often the position of friction damping spring 2 and wedge 1, will too close to the center line of bolster 3
Cause the structure division size B in the middle of 3 liang of wedge grooves of bolster smaller, make the intensity decreases of bolster 3, influence the usability of bogie
Energy.
Please also refer to Fig. 8, in order that section width is that size B is unlikely to too small and influences the strong of bolster 3 in the middle part of bolster
The axis designs of normal friction damping spring 2 and push rod 9 are here with becoming spring 10 and change friction damping in friction damping below by degree
The form that outer spring 11 is not aligned, i.e., the axis of normal friction damping spring 2 and push rod 9 and spring 10 in change friction damping below and change
The axis of spring 11 is misaligned outside friction damping, stagger a segment distance A, that is, normal friction damping spring 2 and push rod 9 are shaken to remote
Deviate a segment distance A in the direction at pillow center.So, the structure division size B in the middle of 3 liang of wedge grooves of bolster just can be each to both sides
Widen a segment distance A, be changed into B+2A, be remarkably improved the structural strength of bolster 3, it is ensured that the performance of bogie.
Assembled after bogie, in push rod lower end and can become in friction damping between the upper end of spring 10 using such a mode
Load bearing 12, the center line of bearing 12 coincides with becoming the axis of spring 10 in friction damping, and the lower end of push rod 9 is supported from above
Be designed to plane in the eccentric position of bearing 12, and by the lower end of push rod 9 and the upper end of bearing 12, when become friction damping in spring 10 by not
The power of centering and during deflection, there is gap, such push rod 9 in the bottom surface of push rod 9 between side and the top surface of bearing 12 away from bolster center
The application point of the active force of bearing 12 can be moved to bolster central side, so as to reduce the offset of power, improve spring stress shape
State.
Fig. 9 is refer to, is unlikely to too small in order that the middle part section width of bolster 3 is size B and influences bolster intensity, may be used also
So that by the central frame mouth larger of side frame 7, the lower section of wedge 1 is located at into spring 10 and change friction damping in middle change friction damping spring
Outer spring 11 to the direction away from bolster center deviates a segment distance C relative to the damping spring of its both sides, also, makes normal friction damping
It is located at the middle axle for becoming spring 10 and the outer spring 11 of change friction damping in friction damping spring below the axis and wedge of spring 2 and push rod 9
Line is overlapped.So, the structure division size B in the middle of 3 liang of wedge grooves of bolster just can respectively widen a segment distance C to both sides, be changed into B
+ 2C, is remarkably improved the structural strength of bolster 3, it is ensured that the performance of bogie.
According to such a structure, then the bottom surface of push rod 9 can be set the conical nest of fovea superior, and the correspondence position of bearing 12 can be designed
The convex circular cone matched somebody with somebody, so that push rod 9 and bearing 12 being capable of automatic centerings under elastic force effect, it is ensured that both axis are highly overlapped,
It is not in skew.
Above-described embodiment can be respectively designed to two schemes, and a kind of scheme is that the diameter of bearing 12 is slightly less than outside change friction damping
The external diameter of spring 11, while pushing down spring inside and outside change friction damping, another scheme is that the diameter of bearing 12 is slightly less than change friction damping
The external diameter of interior spring 10, only pushes down spring 10 in change friction damping.
Figure 10 is refer to, in order to increase the amount of deflection for becoming spring inside and outside friction damping, it is ensured that it has larger free height, this
In circular sinking nest 13 is designed with side frame bearing platform, can be by the change friction damping spring of the lower section of wedge 1 during assembling to accommodate spring
The lower end of interior spring 10 is fitted into the circular sinking nest 13 on side frame bearing platform, and the diameter of sinking nest 13, which is more than, becomes spring in friction damping spring
10 external diameter, and less than the internal diameter of the outer spring of vibration damping, due to only the power of the interior spring of the position being introduced as change friction damping spring, because
This, the external diameter for becoming spring 10 in friction damping should be slightly less than by becoming the external diameter of the upper end bearing of spring 10 in friction damping spring, only pushed down change and rubbed
Wipe spring 10 in vibration damping.
Alternatively, the diameter of sinking nest 13 can also be more than the external diameter for becoming the outer spring 11 of friction damping, during assembling
The lower section of wedge 1 is become into the circle that spring 10 loads on side frame bearing platform simultaneously with the lower end for becoming spring 11 outside friction damping in friction damping spring
In shape sinking nest 13, the diameter of sinking nest 13 is more than the external diameter for becoming the outer spring 11 of friction damping spring, due to by the inside and outside spring of the position
Power be concomitantly introduced into as friction damping spring is become, therefore, becoming the external diameter of the upper end bearing 12 of spring 10 in friction damping spring should be slightly less than
Become the external diameter of the outer spring 11 of friction damping, while pushing down spring inside and outside change friction damping.
The distance between the bottom of sinking nest 13 and cushion cap bottom surface D account for the 20%~50% of side frame bearing platform height, sinking nest 13
Side can account for 20%~40% (see Figure 12) of side frame bearing platform height apart from E with side frame bearing platform side wall.So both it is convenient for
Casting, can ensure that the height for becoming friction damping spring is consistent or close with other pillow springs, reduce spring species, simplify product again
Structural complexity.
Above-described embodiment is only the preferred scheme of the present invention, is specifically not limited thereto, on this basis can be according to reality
Need to make with targetedly adjusting, so as to obtain different embodiments.For example, in step s 4, using other modes
It is relatively fixed wedge 1 and with bolster 3 and is maintained at compression position, etc..Because mode in the cards is more, here just not
Another one illustrates.
No matter the bogie assembled using this method has preferable relative friction coefficient under empty, loaded vehicle state, simultaneously
It can make bogie that there is larger diamond resistant rigidity again, make bogie that there is more preferable vertical and transversal dynamic performance；Meanwhile,
The deficiency of existing double acting damper technique scheme is also overcomed, makes push rod and bearing easy for installation, can be by wedge groove to bolster
The influence of intensity minimizes degree.
In addition, being also effectively reduced the processing step required for assembling bogie, mitigate operation difficulty and labor intensity, and
Improve packaging efficiency and assembly precision, it is to avoid parts are caused to damage in an assembling process, so as to ensure the use of bogie
