The specific embodiment

Now contrast accompanying drawing, describe the concrete enforcement of closed jointing traction buffer system of the present utility model in detail, have clear more and understanding accurately to the technical problems to be solved in the utility model, the technique effect that is reached and technical characterictic thus.

As shown in Figure 1 and Figure 2, closed jointing described in the utility model draws buffer system, comprises the joint 3 of draw gear 1, shock absorber, energy disperser frame 4.Draw gear 1 is the most important device of native system, it mainly acts on is that the company that finishes the traction buffer system hangs, each vehicle is drawn, comprise coupler body 15, convex cone 11, concave cone 14, hook tongue 9, separate shank 12, retracing spring 13, lateral pin 2, air hose coupling 19.Convex cone 11, concave cone 14 are positioned at the front portion of coupler body 15, and lateral pin 2 is installed on the rear portion of draw gear.Coupler body 15 is provided with coupler knuckle chamber 16, is used for hold-down hook tongue 9, and coupler knuckle chamber 16 is between convex cone 11 and concave cone 14.Convex cone 11 front ends are cone shape, this just plays draw gear well and connects the directional tagging of hanging, even be in owing to vehicle reason such as curve bend cause two draw geares do not finish over against the time, two vehicles still can be good at the company of finishing and hang under the guiding of mutual convex cone 11.Air hose coupling 19 is installed in coupler body end face 17, can be provided with one or more according to the car load needs.

As shown in Figure 5, separate shank 12 and be connected with hook tongue 9, retracing spring 13 1 ends with separate shank 12 and be connected, the other end is connected with coupler body 15.Hook tongue 9 is the important stressed member in the draw gear, realizes the locking and the uncoupling of draw gear by swivel hook tongue 9; Separating shank 12 mainly is to be used to promote the rotation of hook tongue 9 in coupler knuckle chamber 16, to realize the locking and the uncoupling of draw gear.

As shown in Figure 6, shock absorber comprises energy disperser frame 4, vertical pin 5, preceding slave plate 6, back slave plate 8, buffer medium 7.Shock absorber is supported on respectively on the forward and backward follower seat on the car body, to reach the purpose that is connected with car body by forward and backward slave plate 6,8.Buffer medium 7, preceding slave plate 6, back slave plate 8, vertical pin 5 are installed in respectively on the energy disperser frame 4.

As Fig. 1, Fig. 2, shown in Figure 7, the joint 3 of energy disperser frame 4 is connected with the afterbody of draw gear 1 with vertical pin 5 one ends by lateral pin 2, and the other end is connected with shock absorber.

Fig. 7 is in two draw geares, 1 company's of being in extension process, and the convex cone 11 in two coupler bodies 15 enters concave cone 14 inside of the other side's coupler body 15 mutually, and hook tongue 9 rotates under the promotion of the other side's convex cone 11.

Fig. 8 is the state after two draw geares, 1 company of finishing hangs, after two coupler body end faces 17 are adjacent to, hook tongue 9 enters the other side's coupler knuckle chamber 16 mutually, hook tongue 9, separate shank 12 under the restoring force effect of retracing spring 13, forward to, with two draw gear lockings, draw gear is finished to connect and is hung like this, can draw normally this moment, need not through hole to be set and the connecting pin of packing in convex cone 11 and concave cone 14.Can further improve the intensity of coupler body 15 like this, improved degree of automation, stopped since the coming off of connecting pin, problems affect such as impaired to the safety of train operation.

The extension process is opposite substantially with even for the uncoupling process of draw gear.
