Abstract
The utility model discloses a flat car hitch frame buffer mechanism comprising a drag handle rod arranged on a hitch frame, wherein a front part of the drag handle rod is provided with a drag handle rod sleeve slidingly fit with the drag handle rod, a front buffer spring assembly and a back buffer spring assembly are arranged behind the drag handle rod sleeve, and a back end of the drag handle rod is provided with a nut used for positioning the drag handle rod, the front buffer spring assembly and the back buffer spring assembly. The flat car hitch frame buffer mechanism of the utility model has the advantages of reasonable structure, and excellent buffer performance.
Description
Technical field
The utility model relates to a kind of flat truck drawbar frame buffer gear.
Background technology
Existing flat truck drawbar frame does not have buffer gear, causes flat truck in starting with to stop time vibrations bigger, makes institute's cargo possibility that drops, and can not satisfy requirement of client.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of the utility model is to provide, the flat truck drawbar frame buffer gear that cushion characteristic is good.
The technical solution of the utility model is:
A kind of flat truck drawbar frame buffer gear; It is characterized in that: comprise being contained in and drag the handle bar on the drawbar frame; Drag the anterior suit of handle bar with drag handle bar bearing fit drag handle bar cover; After dragging handle bar cover, forward and backward recoil spring assembly is set, is dragging the nut of handle rod rear end dress dragging handle bar and forward and backward recoil spring assembly to position.
Said forward and backward recoil spring assembly comprises forward and backward spring, and forward and backward spring is wrapped with rubber.Drag the handle bar to adopt square steel structure bearing fit with dragging handle bar cover.
The utility model is rational in infrastructure, and cushion characteristic is excellent.Particularly the form of " rubber parcel spring " before and after the drawbar frame buffer gear guarantees to drag the handle bar in former and later two directions enough buffering leeway to be arranged all, has guaranteed the smooth running of flat truck effectively; Drag the handle bar to overlap employing square steel structure bearing fit, guarantee to drag the handle bar to seesaw only, can not move up and down, guarantee that tractive force arrives flat truck through the whole smooth transfer of drawbar frame with dragging the handle bar; The required part processing of buffer gear is convenient, and cost is low; The mechanism-trouble rate is very low, firm and durable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
A kind of flat truck drawbar frame buffer gear; Comprise being contained in and drag handle bar 2 on the drawbar frame 1; Drag anterior suit of handle bar and the handle bar that drags that drags handle bar bearing fit to overlap 3; After dragging handle bar cover, forward and backward recoil spring assembly 4,5 is set, is dragging the nut 6 of handle rod rear end dress dragging handle bar and forward and backward recoil spring assembly to position.
Said forward and backward recoil spring assembly comprises forward and backward spring, and forward and backward spring is wrapped with rubber.Drag the handle bar to adopt square steel structure bearing fit with dragging handle bar cover.
Claims (3)
1. flat truck drawbar frame buffer gear; It is characterized in that: comprise being contained in and drag the handle bar on the drawbar frame; Drag the anterior suit of handle bar with drag handle bar bearing fit drag handle bar cover; After dragging handle bar cover, forward and backward recoil spring assembly is set, is dragging the nut of handle rod rear end dress dragging handle bar and forward and backward recoil spring assembly to position.
