Abstract
The utility model relates to a lower center plate draught device of a railway wagon bogie, which is characterized by comprising a lower center plate assembly and a center pin, wherein the center pin is embedded in a center pin hole of the lower center plate assembly, the lower center plate assembly comprises a lower center plate and an elastic wear-resistant bushing, the elastic wear-resistant bushing is embedded in the center pin hole of the lower center plate, and the center pin is inserted into the elastic wear-resistant bushing. The lower center plate draught device comprises the lower center plate assembly and the center pin, wherein the lower center plate assembly comprises the lower center plate and the elastic wear-resistant bushing, the elastic wear-resistant bushing is in transition matching in the center pin hole of the lower center plate, and the center pin is in small clearance matching in the elastic wear-resistant bushing, and therefore, the center pin is effectively avoided being in direct contact with the lower center plate, and the abrasion is avoided. The lower center plate draught device can be widely applied to the field of railway wagon transportation.
Description
Technical field
The utility model relates to a kind of railway goods train bogie truck center plate, particularly about a kind of truck center plate draw gear of railway goods train bogie.
Background technology
At present, adopt cartridge and the common carrying structure of side bearing between the car body of all-purpose vehicle and bogie truck, cartridge abrasion dish is housed in the truck center plate.Body center plate is pressed on the cartridge abrasion dish, and vertical force passes to cartridge abrasion dish from body center plate, and then passes to truck center plate, also can transmit longitudinal force through cartridge simultaneously.The bogie truck of plane truck center plate structure all is equipped with center pin, and center pin is inserted in the hole in the middle of the truck center plate, with the hole of truck center plate big gap is arranged.When vehicle operating, the maximum lateral acceleration that vehicle allows reaches 0.5g, and general operation acceleration/accel also has about 0.3g, and therefore, center pin can produce and rocks from side to side under free situation, and then causes the abrasion of center pin and cartridge centre hole.
Summary of the invention
To the problems referred to above, the purpose of the utility model provides a kind of abrasion that can avoid cartridge and center pin, simple and reliable for structure, reduces the truck center plate draw gear of the railway goods train bogie of car inspection and maintenance work amount.
For realizing above-mentioned purpose, the utility model is taked following technical scheme: a kind of truck center plate draw gear of railway goods train bogie is characterized in that: it comprises truck center plate composition and center pin, and said center pin is embedded in the kingpin hole that said truck center plate is formed; Said truck center plate is formed and is comprised elastic wear-resisting lining and truck center plate, and said elastic wear-resisting lining is embedded in the kingpin hole of said truck center plate, is inserted with said center pin in the said elastic wear-resisting lining.
The internal diameter of said elastic wear-resisting lining is less than the kingpin hole internal diameter of said truck center plate, and the kingpin hole of said elastic wear-resisting lining and said truck center plate adopts transition fit.
Said center pin and elastic wear-resisting lining adopt little free-running fit, and are provided with guiding tapering integrated with it in the lower end of said center pin.
The height of said elastic wear-resisting lining is lower than the degree of depth of the kingpin hole of said truck center plate.
Said elastic wear-resisting lining employing has less friction coefficient high molecular abrasion-proof material and processes.
The utility model is owing to take above technical scheme; It has the following advantages: 1, the utility model is owing to adopt truck center plate to form and the center pin formation; Truck center plate is formed and is comprised truck center plate and elastic wear-resisting lining; The flexible anti-wearing liner of transition fit in the kingpin hole of truck center plate, little free-running fit has center pin in the elastic wear-resisting lining.Therefore, effectively avoid the direct contact of center pin and truck center plate, avoided abrasion.2, the utility model is processed owing to the employing of elastic wear-resisting lining has less friction coefficient high molecular abrasion-proof material, and it is simple and reliable for structure.3, the utility model since adopt center pin not with the truck center plate direct contact, avoided the abrasion between center pin and the truck center plate, meanwhile, can reduce car inspection and maintenance work amount effectively.The utility model can be widely used in in the railway truck transport field.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model when installing and using;
Fig. 2 is that the truck center plate of the utility model is formed structural representation;
Fig. 3 is the center pin structural representation of the utility model;
Fig. 4 is the abrasion nested structure scheme drawing of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is carried out detailed description.
Like Fig. 1～shown in Figure 4, the utility model is in truck center plate, to install the Polymer lining additional, it comprise truck center plate form 1 with center pin 2, center pin 2 is embedded in truck center plate is formed 1 kingpin hole.
As shown in Figure 2; Truck center plate is formed 1 and is comprised elastic wear-resisting lining 3 and truck center plate 4; Elastic wear-resisting lining 3 is embedded in the kingpin hole of truck center plate 4; And in elastic wear-resisting lining 3, be inserted with center pin 2, and make not direct contact of center pin 2 and truck center plate 4, can avoid the abrasion of truck center plate 4 and center pin 2 like this.
In the foregoing description, the internal diameter of elastic wear-resisting lining 3 is less than the kingpin hole internal diameter of truck center plate 4, and elastic wear-resisting lining 3 adopts transition fit with the kingpin hole of truck center plate 4.
Among above-mentioned each embodiment, center pin 2 adopts little free-running fit with elastic wear-resisting lining 3, because the gap between center pin 2 and the elastic wear-resisting lining 3 is less, therefore, is provided with guiding tapering 5 integrated with it (as shown in Figure 3) in the lower end of center pin 2.
Among above-mentioned each embodiment, the height of elastic wear-resisting lining 3 should be lower than the degree of depth of the kingpin hole of truck center plate 4.
Among above-mentioned each embodiment, 3 employings of elastic wear-resisting lining have less friction coefficient high molecular abrasion-proof material and process.
In sum, the utility model makes center pin 2 obtain constraint because elastic wear-resisting lining 3 has been installed in truck center plate 4 like this, thereby avoids the abrasion of center pin 2 and truck center plate 4 effectively.
Above-mentioned each embodiment only is used to explain the utility model; The structure of each parts, size, the position is set and shape all can change to some extent; On the basis of the utility model technical scheme; All improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside the protection domain of the utility model.
