Abstract
The utility model relates to an elastic side bearing for a railway truck, which is characterized by comprising a hollow side bearing base. The side bearing base is arranged on an adjusting liner plate, a side bearing seat and an elastic side bearing body are sequentially arranged inside the side bearing base from inside out, a roller sleeved onto a sleeve shaft is arranged on one side of the side bearing base, a longitudinal locking wedge spacer is arranged on the other side of the side bearing base, a groove is arranged on the top of the side bearing seat, and a side bearing abrasion plate made of non-metal materials is embedded into the groove. Since the side bearing body is arranged on the side bearing base, a rolling shaft component is arranged on the adjusting liner plate on one side of the side bearing body, and the abrasion plate is embedded into the groove on the top of the side bearing body, the rolling shaft component comprising the roller shaft and the roller can increase return resistance torque between a bogie and a truck body, thereby greatly improving running stability of the 30t axle load bogie, and the elastic side bearing can be widely applied to bogies of various railway vehicles.
Description
Technical field
The utility model relates to a kind of railway vehicle accessory, particularly about a kind of elastic side bearing of railway wagon that is installed on the heavy bogie truck of railway truck 30t axle.
Background technology
At present, domestic lorry generally adopts JC type double acting The Constant-Contact Resilient Side Bearings and changes K4 type rubber bodies The Constant-Contact Resilient Side Bearings.Because the heavy haul railway transportation can be given full play to the advantage of concentrated, large, the long distance of railway, all-weather traffic, can under certain road network condition, effectively improve transport capacity, conveying efficiency and transport benefits, reach that transport capacity is big, conveying efficiency is high, labor efficiency is high, traffic cost is low, the transportation profit is high.This point has been verified in domestic and international heavily stressed development fully, therefore develops the 30t bogie truck and is necessary very much.But the elastic side bearing traveled distance that uses on bogie truck at present is less, has the gap between wearing plate and the side bearing longitudinally, makes that easily the gap between wearing plate and the side bearing enlarges gradually, has influenced the anti-effect of crawling of side bearing.In exploitation 30t bogie truck, be badly in need of improving at the shortcoming of above-mentioned existing elastic side bearing.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of elastic side bearing of railway wagon that can improve bogie truck operation stability, the low rigidity of long travel.
For achieving the above object, the utility model is taked following technical scheme: a kind of elastic side bearing of railway wagon, it is characterized in that: it comprises the side bearing base of a hollow, described side bearing base is arranged on one and adjusts on the backing plate, in the described side bearing base, be disposed with a side bearing and an elastic side bearing body from inside to outside and form, a side of described side bearing base is provided with a roller that is set on the Roller Shaft; The opposite side of described side bearing base is provided with a vertical locking shim liner, and the top of described side bearing is provided with a groove, and described groove is embedded in a side bearing wear plate of being made by non-metallic material.
Described elastic side bearing body is formed and is comprised a tapered rubber coating, and described rubber coating is arranged in the outside of described side bearing along taper direction, and this described rubber coating outside is disposed with tapered spacer, another described rubber coating and a tapered overcoat.
Described rubber coating is set to more than two, and folder is established a described spacer between per two described rubber coatings.
The static vertical stiffness that described elastic side bearing body is formed is 0.9 ± 0.1Kn/mm.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model is owing to adopt the side bearing base of a hollow, the side bearing base is arranged on one and adjusts on the backing plate, in the side bearing base, be disposed with side bearing and elastic side bearing body from inside to outside and form, a side of side bearing base is provided with a roller that is set on the Roller Shaft; The opposite side of side bearing base is provided with one and vertically locks shim liner, and is embedded in a side bearing wearing plate in the top groove of side bearing.In vehicle sidewindered, roller can increase the steering resistance square between bogie truck and the car body, had therefore improved the heavy bogie truck operation stability of 30t axle greatly.2, the utility model be gripped with a spacer between per two rubber coatings, and each rubber coating is arranged in the outside of side bearing along taper direction because the elastic side bearing body composition that adopts is made up of multilayer rubber cover and spacer.Therefore realized that the side bearing body is horizontal, the coupling of longitudinal rigidity, and realized the transmission and the vibration damping of vertical load.The utility model can be widely used on the bogie truck of various railway vehicles.
Description of drawings

Fig. 2 is a side bearing body structure scheme drawing of the present utility model
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises the side bearing base 1 of a hollow, side bearing base 1 is arranged on one and adjusts on the backing plate 2, in side bearing base 1, be disposed with a side bearing 3 and an elastic side bearing body from inside to outside and form 4, can adjust the height of side bearing 3 and elastic side bearing body composition 4 by adjusting backing plate 2.One side of side bearing base 1 is provided with a roller 6 that is set on the Roller Shaft 5, and roller 6 is used to increase the steering resistance square between bogie truck and the car body in vehicle sidewinders; The opposite side of side bearing base 1 is provided with a vertical locking shim liner 7 that is used to locate.Be provided with a groove 8 at the top of side bearing 3, groove 8 is embedded in a side bearing wear plate 9 of being made by non-metallic material.
As shown in Figure 2, elastic side bearing body is formed 4 and is comprised a tapered rubber coating 41, rubber coating 41 is arranged in the outside of side bearing 3 along taper direction, and be disposed with tapered spacer 42, another rubber coating 41 and a tapered overcoat 43 in these rubber coating 41 outsides, form tapered double-layer rubber nested structure, and realized the coupling of the horizontal and vertical rigidity of elastic side bearing of railway wagon of the present invention.
In the foregoing description,, rubber coating 41 can also be set to more than two, and folder is established a spacer 42 between per two rubber coatings 41 according to user demand.
In the foregoing description, under the normal temperature situation, the static vertical stiffness of elastic side bearing body composition 4 is 0.9 ± 0.1Kn/mm.
In sum, the utility model in use, form the tapered multilayer rubber cover 41 that has on 4 than high camber by elastic side bearing body, make the utility model not only have vertical bearing function, and have the function that provides vehicle to use the steering resistance square, and the transmission and the vibration damping of vertical load have been realized.
The various embodiments described above only are preferred implementations of the present utility model, and are every based on the changes and improvements on the technical solutions of the utility model in the present technique field, should not get rid of outside protection domain of the present utility model.
