Abstract
The utility model discloses a riveting embedded-type top central plate assembly of a rail wagon, which mainly overcomes the defects in the existing top central plate assembly that a rivet is easy to cut off, or the top central plate assembly is inconvenient to be replaced, or the maintenance is difficult, etc. The riveting embedded-type top central plate assembly comprises a towing beam, a top central plate base and a top central plate, wherein a boss is arranged at the upper surface of the top central plate; a groove is arranged at the lower surface of the top central plate; the boss is embedded in the groove in a transition match state; the periphery of the top central plate is riveted with a lower cover plate of the towing beam by a rivet; and the top central plate is installed and welded with a webplate and the lower cover plate of the towing beam at the same time. The riveting embedded-type top central plate assembly has simple structure and convenient installation, and can not only prevent the connection rivet from being cut off, but also facilitate the maintenance and ensure the operation security of vehicles.
Description
Technical field
The utility model relates to the link between goods train carriage and the chassis, refers to that particularly a kind of railway truck rivets embedded body center plate assembly.
Background technology
At present, the body center plate assembly that railway truck is commonly used mainly contains riveted type, integral type and three kinds of structures such as embedded.Riveted type body center plate assembly is riveted on body center plate on the draw beam by rivet, and its principal feature is simple in structure, easy to maintenance, but has the easy cut possibility of rivet, has brought bigger hidden danger to safety of railway traffic.Integral type body center plate assembly is with body center plate and rear draft lug cast solid, and is fixing with the draw beam welding again, and its principal feature is to have avoided the easy cut possibility of riveted type body center plate rivet, but has brought very big difficulty for maintenance in the future.Embedded body center plate assembly is fixedly welded on bolster center filler on the draw beam, boss and groove by interference fit between bolster center filler and the body center plate are connected, body center plate is also fixing with the draw beam welding simultaneously, its principal feature and integral type body center plate are similar, but need when replacing with cartridge weld seam between body center plate and draw beam is cut off, with special tooling body center plate is taken out, body center plate can not utilize substantially more again, and maintainability is poor.
Summary of the invention
The purpose of this utility model be exactly to provide a kind of simple in structure, easy for installation, can avoid connecting rivet cut off, again can convenient for maintaining, guarantee that the railway truck of vehicle operating safety rivets embedded body center plate assembly.
For achieving the above object, the designed railway truck of the utility model is riveted embedded body center plate assembly, comprise draw beam, bolster center filler and body center plate, be provided with a boss above the described body center plate, be provided with a groove below the described bolster center filler, described boss is embedded in and is the transition fit state in the described groove, is connected with the lower cover riveted joint of draw beam by pulling rivet around the described body center plate, and described bolster center filler is connected with the web of draw beam and the lower cover assembly welding of draw beam simultaneously.
Further, above-mentioned boss adopts disc-shaped structure, and above-mentioned groove adopts the circular counter bore structure with the boss form fit, and round boss and groove simple for structure reliable is convenient to processing and location and installation.
Advantage of the present utility model is: on the basis that does not change body center plate module body structure, on the web and lower cover of draw beam, can make it fixed the different parts assembly welding of bolster center filler; Change the relation of the interference fit between body center plate boss and the bolster center filler groove into the transition fit state, by special tool (as tighting a bolt) the body center plate boss is pressed in the bolster center filler groove, make it have very high resistance to shear, shearing forces such as the braking in the time of both can bearing vehicle operating, impact, can for convenience detachly reuse again, reduce maintenance cost; Be riveted on the draw beam lower cover with the periphery of pulling rivet with body center plate simultaneously, pulling rivet not only is convenient to the repair demolition of body center plate, and can bear various impulsive forces jointly with parts such as body center plates, guarantees railway operation safety.In addition, the utility model is simple in structure, assembling and maintenance are convenient, can reduce the car inspection and maintenance cost, the in-use performance of improvement vehicle, thus improve the shipping work efficiency of vehicle.
Description of drawings
Fig. 1 rivets the structural representation of embedded body center plate assembly for a kind of railway truck;
Fig. 2 is the perspective view of body center plate assembly shown in Figure 1;
Fig. 3 is the perspective view of body center plate among Fig. 2;
Fig. 4 is the perspective view of bolster center filler among Fig. 2.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Railway truck shown in the figure is riveted embedded body center plate assembly, mainly is made of draw beam 1, bolster center filler 2 and body center plate 3.On body center plate 3, be manufactured with the boss 3a of a disc-shaped structure, below bolster center filler 2, be manufactured with the groove 2a of a circular counter bore structure, adopt transition fit between boss 3a and the groove 2a.Adopt special tool that boss 3a is pressed among the groove 2a during assembling.Bolster center filler 2 is connected with the web 1a of draw beam 1 and the lower cover 1b assembly welding of draw beam 1.Then fastening with the lower cover 1b riveted joint of draw beam 1 around the body center plate 3 by pulling rivet 4.Shearing forces such as the braking when body center plate 3 convex platform 3a bear vehicle operating, impact, the pulling rivet 4 main interconnect functions that rise.When body center plate 3 needs repairing, pulling rivet 4 is cut off,, adopt special tool at an easy rate body center plate 3 to be pulled out, repair or change because boss 3a and groove 2a are transition fit.
