Abstract
The utility model belongs to the technical field of railway wagons, and particularly relates to a railway wagon front draft lug. Two front draft lugs are symmetrically fixed on a web of a traction beam through pulling rivets, a coupler yoke is longitudinally placed in an inner cavity of the traction beam, and a coupler yoke key penetrates through the coupler yoke and a hole of a draw gear. The railway wagon front draft lug comprises rib plates, rectangular bottom plates and rectangular stand plates. Each rib plate is a right trapezoid rib plate, the bottom of each rib plate is welded to the corresponding rectangular bottom plate, the height of each right trapezoid rib plate is equal to that of the corresponding rectangular stand plate, the length of the upper bottom of each right trapezoid rib plate is larger than or equal to that of the frame of trail hook, and the included angle between the hypotenuse and the lower bottom of each right trapezoid rib plate is not larger than the maximum swinging angle of the draw gear. The railway wagon front draft lug has the advantages that the swinging of the coupler yoke of a wagon can be limited, transverse impact subjected by the wagon is reduced, and the stability of wagon running is improved. Meanwhile, the abrasion between the coupler yoke and the front draft lugs is reduced, and accordingly the service life of the coupler yoke and the service life of the front draft lugs are prolonged.
Description
Technical field
The utility model belongs to railway truck technical field, is specifically related to a kind of railway truck front draft lug.
Background technology
Along with the increase of the heavy raising of railway truck axle and marshalling quantity, train longitudinal force is increasing.Railway truck longitudinal force is mainly transmitted by parts such as hitch, hook tail frame, draft key, energy disperser and central sills, annexation between each parts is: central sill is fixed on car body, hook tail frame is arranged on central sill by energy disperser, and the two ends of hook tail frame are respectively arranged with front draft lug and rear draft lug.Hook tail frame connects hitch near the end of front draft lug by draft key.Hook tail frame can move along central sill longitudinal direction.In the railroad industry standard TB/T40-1999 of the People's Republic of China (PRC), front draft lug is comprised of triangle gusset, rectangular base plate and rectangle riser three parts, and rectangular base plate and rectangle riser are mutually vertical, and triangle gusset is also simultaneously vertical with rectangular base plate and rectangle riser.Because gusset is shaped as triangle, hook tail frame relative oscillating quantity when swinging with respect to draw beam is likely larger and area of contact is less, easily causes hook tail frame and the wearing and tearing of front draft lug contact site.In vehicle operating process, due to the frequent variation of line condition, the stressing conditions of hook tail frame also can change thereupon.Hook tail frame not only can vertically move along draw beam inner chamber, also can and swing up and down with respect to draw beam left and right.When hook tail frame swings with respect to draw beam, can produce lateral impact forces, make vehicle operating unstable.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of a kind of railway truck front draft lug that can limit the teeter of hook tail frame.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of railway truck front draft lug is symmetrically fixed on the web of draw beam by pulling rivet, hook tail frame is longitudinally placed in the inner chamber of draw beam, in the hole of draft key through hook tail frame and hitch, hitch can draft key be that centre of gration rotates within the specific limits, comprise gusset, rectangular base plate and rectangle riser, described gusset is right-angled trapezium gusset, described right-angled trapezium gusset is gone to the bottom and is welded in described rectangular base plate, described right-angled trapezium gusset height equates with rectangle riser height, the length of described hook tail frame is longer than or is equaled to described right-angled trapezium gusset upper base length, described right-angled trapezium gusset hypotenuse is 15 °～30 ° with the angle angle of going to the bottom.
Preferably, the length that described right-angled trapezium gusset is gone to the bottom equals described rectangular base plate length.
Further, in described rectangular base plate, have several through holes.
Further, on described rectangle riser, have several through holes.
The beneficial effects of the utility model are to limit the swing of vehicle hook tail frame, have reduced the suffered lateral impact forces of vehicle, thereby improve the stability of vehicle operating; Reduce the abrasion of hook tail frame and front draft lug simultaneously, thereby increase the service life of hook tail frame and front draft lug.
Accompanying drawing explanation
Fig. 1 is the elevation cross-sectional view of the utility model embodiment front draft lug.
Fig. 2 is the birds-eye view of the utility model embodiment front draft lug.
Fig. 3 is the utility model embodiment front draft lug installation site schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described in detail.
A kind of railway truck front draft lug 1 is arranged on position shown in Fig. 3, by pulling rivet, be symmetrically fixed on the web of draw beam 2, hook tail frame 3 is longitudinally placed in the inner chamber of draw beam 2, in the hole of draft key 5 through hook tail frame 3 and hitch 4, hitch 4 can rotate for centre of gration by draft key 5 within the specific limits.As depicted in figs. 1 and 2, front draft lug 1 comprises four gussets 11, rectangular base plate 12 and rectangle riser 13, gusset 11 is right-angled trapezium gusset, right-angled trapezium gusset 11 is gone to the bottom and is welded in rectangular base plate 12, right-angled trapezium gusset 11 height highly equate with rectangle riser 13, right-angled trapezium gusset 11 upper base length equal the length of hook tail frame 3, the length that right-angled trapezium gusset 11 is gone to the bottom equals rectangular base plate 12 length, right-angled trapezium gusset 11 hypotenuses and the formation angle α that goes to the bottom, according to 13 ° of the full swing angles of general hitch, we get right-angled trapezium gusset 11 hypotenuses is 15 °～30 ° with the angle [alpha] of going to the bottom, in the present embodiment, getting α is 18 °.In rectangular base plate 12, have several through holes, can rectangular base plate 12 be fixed on draw beam 2 webs by pulling rivet, be convenient to Maintenance and Repair; On rectangle riser 13, have several through holes, can wearing plate be fixed on rectangle riser 13 by Bolt Connection, be convenient for changing wearing plate.
This railway truck front draft lug can limit the swing of vehicle hook tail frame, has reduced the suffered lateral impact forces of vehicle, thereby improves the stability of vehicle operating; Reduce the abrasion of hook tail frame and front draft lug simultaneously, thereby increase the service life of hook tail frame and front draft lug.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
