Abstract
The invention relates to a traction rod structure of a locomotive. The traction rod structure consists of a traction seat barrel and a traction rod body, wherein flanges at two ends of the traction rod body are respectively connected with the traction seat barrel through bolts, the traction rod body and the flanges at the two ends of the traction rod body are in an integrally forged structure, the section of a trunk of the rod body is in an I shape, and parts from the two ends of the rod body to the flanges are in arc transition. The traction rod structure disclosed by the invention is simple in structure, high in integrated intensity and good in fatigue performance, the influence of welding factors on quality is completed avoided, and the application safety of the locomotive is effectively guaranteed.
Description
Technical field
The present invention relates to a kind of locomotive traction bar structure, belong to locomotive manufacturing technical field.
Background technology
Locomotive traction bar structure mainly bears tractive force and the braking force of locomotive, and stress condition is comparatively severe, higher to the requirement of safety factor.As shown in Figure 1, the locomotive traction bar structure of prior art generally adopts split type, is made up of traction seat cylinder 1 and the traction body of rod 2.The trunk of the traction body of rod 2 is solid drawn pipe, and its end flange 3 and solid drawn pipe are by carrying out periphery welding again behind bolt-type free-running fit location.During locomotive operation, draw bar structure not only subjects tractive force on locomotive operation direction and braking force, also will bear the deflection force in horizontal surface and the twisting resistance in vertical surface.These power all will act on two weld seams 5 of the traction body of rod, cause weld stress to concentrate.Welding quality slightly flaw just easily causes the fracture of the traction body of rod, affects the safe in operation of locomotive.
Summary of the invention
Object of the present invention overcomes the deficiency of above-mentioned prior art exactly, provides a kind of locomotive traction bar structure.
The object of the present invention is achieved like this: a kind of locomotive traction bar structure, be made up of traction seat cylinder and the traction body of rod, the flange at traction body of rod two ends is connected with traction seat cylinder respectively by bolt, it is characterized in that the described traction body of rod and two end flanges thereof are integral type forging structure, the cross section of body of rod trunk is I-shape, and body of rod two ends to flange is arc transition.
Technical scheme of the present invention, structure is simple, and bulk strength is high, superior fatigue resistance, has stopped the impact of welding factor on quality completely, effectively ensure that the application safety of locomotive.
Accompanying drawing explanation
Fig. 1 is the locomotive traction bar structural representation of prior art.
Fig. 2 is the locomotive traction bar structural representation of the embodiment of the present invention.
Fig. 3 is that A-A in Fig. 2 is to cutaway view.
Be labeled as in figure: 1-traction seat cylinder, 2-draws the body of rod, 3-flange, 4-bolt, 5-weld seam.
Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Referring to accompanying drawing 2 and 3, the locomotive traction bar structure of the present embodiment, be made up of traction seat cylinder 1 and the traction body of rod 2, the flange 3 at the traction body of rod 2 two ends is connected with traction seat cylinder 1 respectively by bolt 4.The traction body of rod 2 and two end flanges 3 thereof are integral type forging structure, ensure the high strength of the body of rod.The cross section of the body of rod 2 trunk is I-shape, while guarantee lever strength, plays the effect of loss of weight.The body of rod 2 two ends are arc transition to flange 3 place, avoid stress and concentrate.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
