Abstract

The utility model discloses a dust-proof center disc component of a railway wagon bogie, mainly solving the defect that the traditional railway wagon center disc component does not have a dust-proof structure. The designed dust-proof center disc component comprises an upper center disc and a lower center disc; a center disc wearing disc is arranged between the upper center disc and the lower center disc; a dust-proof sealing ring which is elastically contacted with the disc edges of the upper center disc and the lower center disc is arranged between the disc edges of the upper center disc and the lower center disc; the dust-proof sealing ring is positioned at the outer side of the center disc wearing disc, thus leading the matched surfaces of the center disc wearing disc, the upper center disc and the lower center disc to be isolated from the external environment. The dust-proof center disc component has simple structure and convenient installation, can effectively prevent the hard foreign matters of sands, dusts and powder particles and the like from invading, and ensure the reliable running and installation of the wagon.

Description

The railway goods train bogie cartridge assembly that prevents dust

Technical field

The utility model relates to the upper and lower cartridge assembly on the railway goods train bogie, refers to a kind of railway goods train bogie cartridge assembly that prevents dust particularly.

Background technology

Railway truck is when operation, and the force transmission between the car body on its top and the bogie truck of base carrier need realize by the upper and lower cartridge assembly that is arranged on therebetween.The upper and lower cartridge of traditional railway truck is connected by center pin, is provided with cartridge abrasion dish between the upper and lower cartridge, and cartridge abrasion dish generally is installed in truck center plate, and it is simple in structure, be convenient to maintenance, but does not have dustproof construction.When vehicle in the desert, mine etc. is when moving under the rugged environment, hard foreign material such as extraneous sand and dust, powder enter in the slit between body center plate, cartridge abrasion dish and the truck center plate easily, aggravate the abrasion of these easily worn parts, reduce its in-use performance, shorten its service life, so not only increase the operating maintenance cost of vehicle, and significantly reduced the shipping work efficiency of vehicle.

Summary of the invention

The purpose of this utility model to provide exactly a kind of simple in structure, easy for installation, can effectively stop hard foreign material such as sand and dust, powder to invade, guarantee that vehicle operating installs the dustproof cartridge assembly of failure-free railway goods train bogie.

For achieving the above object, the dustproof cartridge assembly of railway goods train bogie that the utility model is designed, comprise body center plate and truck center plate, be provided with cartridge abrasion dish between described body center plate and the truck center plate, its special character is: be provided with and its Elastic Contact dust-proof seal ring between the dish edge of described body center plate and truck center plate, described dust-proof seal ring is positioned at the outside of cartridge abrasion dish, thereby makes the fitting surface of cartridge abrasion dish, body center plate and truck center plate and external environment is isolated comes.

Further, described dust-proof seal ring is embedded in the annular groove on the dish edge of truck center plate, perhaps is embedded in the annular groove on the dish edge of body center plate.

Principle of work of the present utility model is that dust-proof seal ring is pressed in the annular groove of truck center plate or body center plate, when upper and lower cartridge cooperates, dust-proof seal ring is subjected to the extruding of upper and lower cartridge, with upper and lower cartridge peripheral plane closed contact, the fitting surface of upper and lower cartridge and cartridge abrasion dish are surrounded by dust-proof seal ring and are isolated from the outside at this moment, thereby have prevented that hard foreign material such as sand and dust, powder from entering between body center plate, truck center plate and the cartridge abrasion dish.

Advantage of the present utility model is: on the basis that does not change upper and lower cartridge agent structure, only, the dust-proof seal ring that an elastomeric material makes just can effectively isolate element easy to wear by being set, thereby significantly having reduced extraneous harsh environment corrodes the wearing and tearing of upper and lower cartridge and cartridge abrasion dish, it is simple in structure, assembling and maintenance are convenient, upper and lower cartridge can exchange with common cartridge and use, and the replacing after dust-proof seal ring and cartridge abrasion mill decrease is also very convenient.Like this, not only effectively prolong the service life of upper and lower cartridge and cartridge abrasion dish, reduced the accessory turnover rate, reduced the car inspection and maintenance cost, and effectively improved the vehicle operation performance, significantly improved the shipping work efficiency of vehicle.

Description of drawings

Fig. 1 is a structural representation of offering the dustproof cartridge assembly of railway goods train bogie of annular groove on the truck center plate;

Fig. 2 is a structural representation of offering the dustproof cartridge assembly of railway goods train bogie of annular groove on the body center plate.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

The cartridge assembly that prevents dust of railway goods train bogie as shown in Figure 1, comprise body center plate 4 and truck center plate 1, be provided with cartridge abrasion dish 3 between body center plate 4 and the truck center plate 1, offer annular groove on the dish edge of truck center plate 1, the cross section semicircular in shape or the half elliptic of this annular groove, this annular groove is positioned at the outside of cartridge abrasion dish 3, and dust-proof seal ring 2 is embedded in this annular groove, the dish edge and dust-proof seal ring 2 Elastic Contact of car load completion back body center plate 4 and truck center plate 1.During concrete the assembling, earlier truck center plate 1 is assembled on the truck bolster 7, the foreign material such as dust greasy dirt on cleaning truck center plate 1 card are assembled to cartridge abrasion dish 3 on the truck center plate 1; Clear up the dust foreign material in the annular groove on the truck center plate 1 dish edge then, dust-proof seal ring 2 is pressed in it; Body center plate 4 is assembled on the truck body 6, the truck body 6 that body center plate 4 is housed drops on the bogie truck again, by the connection of center pin 5, body center plate 4 is cooperated with truck center plate 1 for one get final product.

The cartridge assembly that prevents dust of railway goods train bogie as shown in Figure 2, basic identical with the structure among Fig. 1, offer annular groove on the dish edge of different is body center plate 4, the cross section of this annular groove is semicircular in shape or half elliptic also, this annular groove is positioned at the outside of cartridge abrasion dish 3 equally, dust-proof seal ring 2 is embedded in this annular groove, the dish edge and dust-proof seal ring 2 Elastic Contact of car load completion back body center plate 4 and truck center plate 1.

Because hard foreign material such as extraneous sand and dust, powder are blocked in outside body center plate 4, truck center plate 1 and the cartridge abrasion dish 3 by dust-proof seal ring 2, the wearing and tearing of body center plate 4, truck center plate 1 and cartridge abrasion dish 3 have effectively been avoided, so also as safe as a house reliable when vehicle moves under harsies environment such as desert, mine.
