Abstract
The utility model discloses a traction spherical hinge with a low-falling-possibility backstop for a railway locomotive, which comprises an inner core, an elastic rubber body and an outer sleeve, wherein the elastic rubber body is positioned outside the inner core; the elastic rubber body and the inner core are bonded into a whole through vulcanizing; the outer sleeve is arranged outside the elastic rubber body; a backstop is arranged between the elastic rubber body and the outer sleeve on at least one end in the axial direction of the spherical hinge; and the backstop and the outer sleeve are fixed through a plurality of fixing pins. The traction spherical hinge disclosed by the utility model is a spherical hinge with a low-falling-possibility backstop; and the backstop and the outer sleeve are fixed by the fixing pins, the backstop is less prone to fall from between the elastic rubber body and the outer sleeve, thereby ensuring that the driving process is safer.
Description
Technical field
The utility model relates to a kind of elasticity ball pivot, relates in particular to the traction ball pivot of backstop difficult drop-off for a kind of railway locomotive.
Background technique
Elasticity ball pivot of the prior art comprises inner core, elastic rubbery body, backstop and overcoat, between overcoat and elastic rubbery body, be provided with backstop, because ball pivot in use bears the thrust load that the deadweight of traction/constrictor produces, the radial load that the hauling capacity of a locomotive and braking force of train produce, the warping force that the horizontal relative displacement occurring in locomotive operation process changes into, under the impact force acting in conjunction producing in the deflecting force that the upper and lower relative displacement of car body and bogie causes and train operation, often occur that ball pivot overcoat flange position is pushed up directly, finally cause backstop to come off, affect traffic safety, reason is under above-mentioned force action, and the axial force producing when rubber deformation is greater than overcoat when blocking the flange power of backstop and the friction of backstop and outer inner room, and flange will be by top directly.
Model utility content
The utility model aims to provide the traction ball pivot of backstop difficult drop-off for a kind of railway locomotive, to avoid ball pivot in use to be pushed up directly at ball pivot overcoat flange position, and the problem that finally causes backstop to come off.
The utility model is the traction ball pivot of backstop difficult drop-off for a kind of railway locomotive, comprises inner core, elastic rubbery body and overcoat; Described elastic rubbery body is positioned at inner core outside, and elastic rubbery body becomes an integral body with inner core by bonding by Vulcanization; Described overcoat is arranged at the outside of described elastic rubbery body, between the elastic rubbery body of the axial wherein one end of ball pivot and overcoat, is provided with backstop, between described backstop and overcoat, by a plurality of fixing pins, fixes.
Optionally, between described backstop and overcoat, by a plurality of fixing pins that distribute along backstop even circumferential, fix.
Optionally, the end of described overcoat is along being circumferentially provided with for blocking the turn-up portion of backstop.
Optionally, one end vertically, the inner side of described inner core is provided with shoulder portion.
Optionally, the internal cavities of described inner core is taper type.
Optionally, described inner core is metal inside.
Optionally, described overcoat is metal-coating.
Optionally, described backstop is metal stopper.
Optionally, the sectional shape of described fixing pin is circle, triangle, quadrilateral or Hexagon.
The utility model is the traction ball pivot of backstop difficult drop-off for railway locomotive, owing to having increased a plurality of fixing pins between described backstop and overcoat, backstop between elastic rubbery body and overcoat, come off need axial force that rubber deformation produces be greater than overcoat for block the flange power of backstop and backstop with inner room friction and cut off a plurality of fixing pins with joint efforts, therefore the backstop that increases a plurality of fixing pins is difficult for coming off between elastic rubbery body and overcoat, makes driving safer.
Accompanying drawing explanation
Fig. 1 is the structural representation of the traction ball pivot of backstop difficult drop-off for railway locomotive of the present utility model.
In figure, mark is illustrated as: 1-inner core; 2-elastic rubbery body; 3-overcoat; 4-backstop; 5-fixing pin; 6-turn-up portion; 7-shoulder portion; 8-internal cavities.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is further elaborated.
Referring to Fig. 1, the ball pivot of backstop difficult drop-off for the railway locomotive of the present embodiment, comprises inner core 1, elastic rubbery body 2 and overcoat 3; Described elastic rubbery body 2 is positioned at inner core 1 outside, and elastic rubbery body 2 becomes an integral body with inner core 1 by bonding by Vulcanization; Described overcoat 3 is arranged at the outside of described elastic rubbery body 2, between the elastic rubbery body 2 of the axial wherein one end of ball pivot and overcoat 3, is provided with backstop 4, fixing by a plurality of fixing pins 5 between described backstop 4 and overcoat 3.
The traction ball pivot of backstop difficult drop-off for above-mentioned railway locomotive, owing to having increased between described backstop and overcoat, a plurality of fixing pins 5 are fixing, backstop between elastic rubbery body and overcoat, come off need axial force that rubber deformation produces be greater than overcoat for block the flange power of backstop and backstop with inner room friction and cut off a plurality of fixing pins with joint efforts, therefore the backstop that increases a plurality of fixing pins is difficult for coming off between elastic rubbery body and overcoat, makes driving safer.
In the present embodiment, optional, fixing by a plurality of fixing pins that distribute along backstop 4 even circumferentials 5 between described backstop 4 and overcoat 3.So arrange, can be by backstop 4 and stable being fixed together of overcoat 3.Certainly, a plurality of fixing pins 5 between described backstop 4 and overcoat 3 also can be along circumference uneven distribution.The sectional shape of described fixing pin 5 is preferably circle, triangle, quadrilateral or Hexagon, can certainly, for other shape, not repeat them here.
In the present embodiment, optional, the end of described overcoat 3 is along being circumferentially provided with for blocking the turn-up portion 6 of backstop 4.So arrange, backstop 4 can be blocked.
In the present embodiment, one end vertically, the inner side of described inner core 1 is preferably provided with shoulder portion 7, also setting table shoulder not.
In the present embodiment, optional, the internal cavities 8 of described inner core 1 is taper type or cylindrical.
In the present embodiment, optional, described inner core 1 is metal inside.
