Abstract
The invention relates to a friction-varying hanging-type shock-absorption bogie. The friction-varying hanging-type shock-absorption bogie comprises wheel sets, side frames, bearing components, hanging-type friction-varying shock absorbers, a swing bolster and a brake system, wherein each hanging-type friction-varying shock absorber comprises a shock absorber shell, springs, a threaded lifting rod, a support plate and nuts; the hanging-type friction-varying shock absorbers are suspended on the side frames by the threaded lifting rods and the nuts; the threaded lifting rods penetrate through the shock absorber shells and the support plates in sequence; two ends of each threaded lifting rod are matched with the nuts; the springs are installed between the shock absorber shells and the support plates. According to the invention, not only can the shock-absorption friction matched with an empty vehicle and low dead weight capacity be provided, but also the shock-absorption friction matched with other dead weight capacity also can be provided; the hanging-type friction-varying shock absorbers are installed with pre-compression amount, and as the increase of dead weight capacity, the spring compression amount also increases; a hanging-type structure is adopted by the bogie, and the compression amount and the horizontal rigidity for bearing steel springs decrease, so that the horizontal force between wheel rails is lowered, the wheel rim abrasion is alleviated, and the bogie can smoothly pass by a curve line.
Description
Technical field
The invention belongs to railway goods train bogie field, relate to a kind of bogie truck of Installation of New Type shock absorber.
Background technology
The snubber of railway truck adopts two kinds of forms conventionally: a kind of is normal friction shock absorber with pre compressed magnitude; Another kind is the change friction shock absorber of not being with pre compressed magnitude.But these two kinds of shock absorbers have limitation separately: the vibration damping friction force and the diamond resistant rigidity that with the change friction shock absorber of pre compressed magnitude, at empty wagons and load carrying ability hour, do not provide are all smaller, can not provide good vibration damping and drive ability for empty wagons and little load-carrying operating mode; Although can provide larger vibration damping friction force and diamond resistant rigidity for empty wagons and little load-carrying operating mode with the normal friction shock absorber of pre compressed magnitude, the vibration damping friction force that it provides and diamond resistant rigidity are less 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, provide a kind of change friction force hanging vibration damping bogie truck, use hanging change friction shock absorber, not only make shock absorber have when mounted certain pre compressed magnitude, and vibration damping friction force that shock absorber provides and diamond resistant rigidity are associated with the load carrying ability of bogie truck, the friction force and the diamond resistant rigidity that provide same load carrying ability to match; And owing to having adopted hanging vibration-proof structure, reduced the transverse force between wheel track, improved curving performance.
For achieving the above object, the present invention adopts following technical proposals:
The hanging vibration damping bogie truck of change friction force, comprises that wheel is to, bogie side frame, load bearing component, hanging change friction shock absorber, bolster and brake system; Described hanging change friction shock absorber comprises shock absorber shell, spring, screw thread suspension rod, supporting plate and nut; Described hanging change friction shock absorber hangs on bogie side frame by screw thread suspension rod and nut; Described screw thread suspension rod is successively through shock absorber shell and supporting plate, and 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 truck of described change friction 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 ，Gai inclined-plane, inclined-plane and matches with the inclined-plane of bolster.
Principle of the present invention is: the feature of this bogie truck is to adopt the hanging change friction force shock absorber with pre compressed magnitude, this shock absorber has certain pre compressed magnitude when mounted, and its pre compressed magnitude can regulate by screw thread pair, relatively large vibration damping friction force can be provided when unladen weight or little load-carrying, increase vibration damping friction force along with bogie truck load carrying ability also increases simultaneously, this bogie truck not only can provide the vibration damping friction force that same empty wagons matches like this, the vibration damping friction force that also can provide same load carrying ability to match; And in 1 bogie truck, 4 shock absorbers are owing to having pre compressed magnitude, larger diamond resistant rigidity not only can be provided when empty wagons, suppress the crawl unstability of empty wagons under fair speed, and along with load carrying ability increases, the amount of compression of shock absorber also increases, diamond resistant rigidity also increases thereupon, also can suppress the crawl unstability of loaded vehicle under fair speed.(fully loaded when heavy vibration damping friction force and diamond resistant rigidity improve 20%～40% than normal friction damping device) and because this bogie truck has adopted the structure of hanging vibration damping, the lateral stiffness of its bearing spring will reduce to some extent, and this feature is to reducing the transverse 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: the vibration damping friction force that this bogie truck not only can provide same empty wagons and little load carrying ability to match, the vibration damping friction force that also can provide same load carrying ability to match; Hanging change friction shock absorber has pre compressed magnitude when mounted, and along with load carrying ability increases, its amount of spring compression also increases thereupon; This bogie truck has adopted hanging structure, and amount of compression and the lateral stiffness of its carrying steel spring will reduce to some extent, to reducing the transverse force between wheel track, reduces wheeling edge wearing and by curve, has facilitation smoothly.
