Description
Technical field
The invention belongs to railway goods train bogie field, relate to a kind of bogie of Installation of New Type shock absorber.
Background technology
The friction shock absorber of railway freight-car adopts two kinds of forms conventionally: a kind of is normal friction shock absorber with pre compressed magnitude; SeparatelyA kind of is the change friction shock absorber of not being with pre compressed magnitude. But these two kinds of shock absorbers have limitation separately: be not with pre compressed magnitudeChange friction shock absorber the vibration damping frictional force and the diamond resistant rigidity that provide at empty wagons and loading capacity hour all smaller, can not be emptyCar and little load-carrying operating mode provide good vibration damping and runnability; Although can be empty wagons with the normal friction shock absorber of pre compressed magnitudeProvide larger vibration damping frictional force and diamond resistant rigidity with little load-carrying operating mode, but its vibration damping frictional force and diamond resistant rigidity of providing existLess than normal again under heavy－duty operating mode.
Summary of the invention
The object of the invention is for overcoming the deficiencies in the prior art, a kind of hanging vibration damping bogie of frictional force that becomes is provided, use hangingBecome friction shock absorber, not only make shock absorber have when mounted certain pre compressed magnitude, and make vibration damping frictional force that shock absorber provides andDiamond resistant rigidity is associated with the loading capacity of bogie, the frictional force and the diamond resistant rigidity that provide same loading capacity to match; And owing to adoptingWith hanging vibration-proof structure, reduce the cross force between wheel track, improve curving performance.
For achieving the above object, the present invention adopts following technical proposals:
A kind of hanging vibration damping bogie of frictional force that becomes, comprises that wheel is to, bogie side frame, load bearing component, hanging change friction shock absorber, bolsterAnd brakes; Described hanging change friction shock absorber comprises shock absorber shell, spring, screw thread suspension rod, supporting plate and nut; Described extensionFormula becomes friction shock absorber and hangs on bogie side frame by screw thread suspension rod and nut; Described screw thread suspension rod passes shock absorber shell and supporting plate successively,Screw thread suspension rod two ends are all combined with nut, and described spring fitting is between shock absorber shell and supporting plate.
As a further improvement on the present invention, the hanging vibration damping bogie of described change frictional force also comprises adapter and/or axle box.
On described bogie side frame, have central square hole, hanging change friction shock absorber is arranged between bolster and this central authorities' square hole sidewall.
Described shock absorber shell is provided with inclined-plane, and this inclined-plane matches with the inclined-plane of bolster.
Principle of the present invention is: the feature of this bogie is to adopt the hanging change frictional force shock absorber with pre compressed magnitude, this vibration dampingDevice has certain pre compressed magnitude when mounted, and its pre compressed magnitude can regulate by screw thread pair, can be in unladen weight or littleWhen load-carrying, provide relatively large vibration damping frictional force, simultaneously along with the increase vibration damping frictional force of bogie loading capacity also increases, like thisThe vibration damping frictional force that this bogie not only can provide same empty wagons to match, the vibration damping friction that also can provide same loading capacity to matchPower; And in 1 bogie 4 shock absorbers are owing to having pre compressed magnitude, not only can in the time of empty wagons, provide larger anti-water chestnut firmDegree, suppresses the crawl unstability of empty wagons under fair speed, and along with loading capacity increases, the decrement of shock absorber also increases, anti-Water chestnut rigidity also increases thereupon, also can suppress the crawl unstability of loaded vehicle under fair speed. (vibration damping frictional force and anti-water chestnut when fully loaded weightThe normal friction damping device of ratio of rigidity improves 20%～40%) and because this bogie has adopted the structure of hanging vibration damping, it carries bulletThe lateral stiffness of spring will reduce to some extent, and this feature is to reducing the cross force between wheel track and having facilitation by curve smoothly.
The invention has the beneficial effects as follows, compared with prior art, the present invention has the following advantages: this bogie not only can provideThe vibration damping frictional force matching with empty wagons and little loading capacity, the vibration damping frictional force that also can provide same loading capacity to match; Hanging changeFriction shock absorber has pre compressed magnitude when mounted, and along with loading capacity increases, its amount of spring compression also increases thereupon; This turns toFrame has adopted hanging structure, and decrement and the lateral stiffness of its carrying steel spring will reduce to some extent, to reducing the cross force between wheel track,Reduce wheeling edge wearing and have facilitation by curve smoothly.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As Fig. 1 and Fig. 2, the hanging vibration damping bogie of described change frictional force comprises that 2 wheels are to forming 1; 2 bogie side frame compositions 2; 4Individual hanging change friction damping device 3; 1 bolster composition 4; 2 bearing spring compositions 5; 1 brake rigging 6. DescribedHanging change friction shock absorber 3 is suspended on bogie side frame composition 2 by screw thread suspension rod 8, and the vertical plane of shock absorber shell 9 forms with bogie side frameThe vertical plane of 2 central square hole matches; The inclined-plane of shock absorber shell 9 matches with the inclined-plane of bolster composition 4.
As Fig. 3 and Fig. 4, described change rub hanging shock absorber by nut 7, screw thread suspension rod 8, shock absorber shell 9, spring 10,Supporting plate 11 forms. Described hanging change friction shock absorber 3 hangs on bogie side frame composition 2 by screw thread suspension rod 8 and nut 7; DescribedScrew thread suspension rod 8 is successively through shock absorber shell 9 and supporting plate 11, and screw thread suspension rod 8 two ends are all combined with nut 7, and described spring 10 is pacifiedBe loaded between shock absorber shell 9 and supporting plate 11.
The present embodiment can have larger vibration damping frictional force and diamond resistant rigidity (ratio change friction damping under empty wagons and little load-carrying operating modeDevice improves 20%～50%), vibration damping frictional force and diamond resistant rigidity can be associated with the loading capacity of bogie again, there is loading capacityIncrease, (when fully loaded weight, vibration damping frictional force and diamond resistant rigidity are than normal friction for the characteristic that vibration damping frictional force and diamond resistant rigidity also increase thereuponVibration absorber improves 20%～40%).
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned, not the limit to protection domain of the present inventionSystem, one of ordinary skill in the art should be understood that on the basis of technical scheme of the present invention, those skilled in the art do not need to payGo out various amendments that creative work can make or distortion still in protection scope of the present invention.
