Abstract
A novel hook traction mechanism of underground train positioned at both ends of the inferior part of the vehicle body underframe, comprises a hook, a buffer beam and a body bolster, wherein, the front side face of the buffer beam is connected with an anti-creeper and both ends of the buffer beam and the body bolster are respectively fixed with underframe edge beams. The utility model is characterized in that: the buffer beam and the hook are fixed; both ends of the buffer beam are welded with dilated connection boards and riveted with the underframe edge beams through the connection boards; thereby, longitudinal force generated by traction or braking of underground train is directly transferred from the hook to the buffer beam and then to the underframe edge beams at both sides, making full use of both side edge beams as force transferring carrier with end walls and floors not being distorted or damaged; meanwhile, the buffer beam is connected with the edge beams through riveting mode to eliminate thermal stress and reduce stress distortion, thereby, when serious unexpected accident occurs, the longitudinal force exceeding longitudinal allowable stress only damages the buffer beam, and after the accident the damaged buffer beam is replaced with a new one without affecting the underground train performance, being very convenient for maintenance.
Description
Technical field
The utility model relates to a kind of railcar drawbar coupler mechanism, belongs to the railcar trailer coupling
Technical field.
Background technology
The slow mechanism of pillow pulling that is made up of draw beam, sleeper beam, buffer beam is an important stressed member of railcar and railway passenger train, is installed in two ends, car body underframe bottom, is used to install devices such as hitch.The structure and the mounting means of the slow mechanism of pillow pulling are directly connected to the vehicle overall performance, the general employing of the slow mechanism of the pillow pulling of passenger train formed the integral solder structure with draw beam, sleeper beam, buffer beam in the past, not only be welded to connect during installation, but also be welded to connect with the floor with the underframe side bar.Train traction or glancing impact, longitudinal force pass via hitch and pass to behind draw beam above the sleeper beam again, and be less to both sides side bar power transmission.When longitudinal force reaches or surpass the vertical permissible stress of car body, can cause deformation and failure to headwall and floor, thereby the safety performance of car load is descended, be not easy to maintenance.In addition, the slow mechanism of pillow pulling adopts welding manner also to be easy to generate thermal stress with being connected of car body underframe, causes stress deformation, thereby influences the mechanical property of the slow mechanism of pillow pulling.Referring to Fig. 1,1 is hitch among the figure, and 2 is anti-creeper, and 3 is buffer beam, and 4 is draw beam, and 5 is sleeper beam, and 6 is the underframe side bar, arrow signal longitudinal force direction of transfer.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of railcar novel hitch trailer coupling.
The technical scheme that its technical matters that solves the utility model adopts is as follows: the novel hitch trailer coupling of a kind of railcar, be installed in two ends, car body underframe bottom, comprise hitch, buffer beam, sleeper beam, the buffer beam leading flank is connected with anti-creeper, captive joint with the underframe side bar respectively in the two ends of buffer beam and sleeper beam, it is characterized in that: described buffer beam is captiveed joint with hitch, and the buffer beam two ends are welded with the connecting panel of widening, and by connecting panel and underframe side bar riveted and fixed.
The beneficial effects of the utility model are as follows: the utility model has been cancelled draw beam, changed the power transfer mode that is subjected to of the slow mechanism of traditional pillow pulling, longitudinal force vehicle towed or that braking is produced is directly delivered on the buffer beam from hitch, pass to the underframe side bar of both sides through buffer beam, again by the underframe side bar pass to sleeper beam and with mechanism such as sleeper beam bonded assembly bogie truck, made full use of the carrier of both sides side bar like this as the power of transmission, improved the overall performance of trailer coupling, after adopting this mode, when in the train travelling process during something unexpected happened, headwall no longer participates in bearing longitudinal force, can not deform and destroy; Simultaneously trailer coupling can be directly with relative thin a little less than the floor be connected, make the floor not bear longitudinal force, the floor can not produce deformation and failure; Buffer beam is connected with side bar by the riveted joint mode, work simplification, eliminated thermal stress, reduced stress deformation, when great contingency took place vehicle, the longitudinal force that surpasses vertical permissible stress was only destroyed buffer beam, the buffer beam that need only more renew after the accident, and vehicle performance is unaffected, is convenient to maintenance.

Fig. 2 is the novel hitch trailer coupling of a utility model railcar scheme drawing.
Fig. 3 is the structure schematic top plan view of buffer beam in the novel hitch trailer coupling of the utility model railcar.
The specific embodiment
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in further detail.But the utility model is not limited to given example.
As shown in Figures 2 and 3, the novel hitch trailer coupling of the utility model railcar, be installed in two ends, car body underframe bottom, comprise hitch 1, buffer beam 3, sleeper beam 5, buffer beam 3 leading flanks are connected with anti-creeper 2, and buffer beam 3 is captiveed joint with hitch 1 by the hitch mount pad 32 on it, and buffer beam 3 two ends are welded with the connecting panel of widening 31, and by connecting panel 31 and underframe side bar 6 riveted and fixed, the two ends of sleeper beam 5 and underframe side bar 6 riveted and fixed.
In order to make directly and hitch bonded assembly buffer beam has enough intensity, in embodiment as shown in Figure 3, the further feature of the utility model is: buffer beam 3 is by web 35, strengthens the upper cover plate (being to draw among the figure) of gusset 34, hitch mount pad, the plate-girder that lower cover 37 is welded.
Claims (2)
1, the novel hitch trailer coupling of railcar, be installed in two ends, car body underframe bottom, comprise hitch, buffer beam, sleeper beam, the buffer beam leading flank is connected with anti-creeper, captive joint with the underframe side bar respectively in the two ends of buffer beam and sleeper beam, it is characterized in that: described buffer beam is captiveed joint with hitch, and the buffer beam two ends are welded with the connecting panel of widening, and by connecting panel and underframe side bar riveted and fixed.
2, the novel hitch trailer coupling of railcar according to claim 1 is characterized in that: described buffer beam is by web, strengthens gusset, the upper cover plate of hitch mount pad, the plate-girder that lower cover is welded.
