Fig. 3 be among the utility model embodiment hitch with the be connected section-drawing of shock absorber with hitch.
Wherein, 1-framework, 2-draft key mounting hole, 3-first baffle plate, 4-lower back panel, 5-second baffle, 6-energy disperser, 7-slave plate, 8-draft key, the pipe link of 9-hitch, 10-containing cavity.
The specific embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked; Below in conjunction with accompanying drawing and preferred embodiment, the hook tail frame that proposes according to the utility model and the hitch that comprises this hook tail frame specific embodiment and the principle of work with shock absorber is elaborated.
Can know that by Fig. 1 and Fig. 2 the hook tail frame in the utility model comprises: framework 1, first baffle plate 3, lower back panel 4, second baffle 5.The square billet of framework 1 for being parallel to each other, the plate face of lower back panel 4 is vertically fixed on an end of framework 1, forms concave panel in the side.First baffle plate 3 and second baffle 5 be all perpendicular to the plate face of lower back panel 4, and all be fixed on 1 of framework, forms containing cavity 10 with framework 1, aft end face 4.Preferably, first baffle plate 3 is parallel to each other with second baffle 5, and is separately fixed on the two ends concave panel that is formed by framework 1 and lower back panel 4.Preferably, the chamber wall equal in length of the containing cavity 10 that forms by first baffle plate 3, second baffle 5, and be shorter than the chamber wall length of the containing cavity 10 that forms by framework 1.Preferred again, the root of the chamber wall of the containing cavity 10 that is formed by first baffle plate 3, second baffle 5 all aligns with the bottom surface of lower back panel 4.Also level offers draft key mounting hole 2 above framework 1.
Hitch in the utility model comprises with shock absorber: above-mentioned hook tail frame, energy disperser, slave plate, draft key; Energy disperser is arranged in the containing cavity 10 of above-mentioned hook tail frame, and slave plate is arranged on by the outer face of energy disperser, and the plate of slave plate is in the face of the outer face to energy disperser.The plate face width degree of slave plate is less than or equal to the plate face length degree of chamber wall spacing, slave plate of the containing cavity of being made up of the framework 1 of above-mentioned hook tail frame 10 greater than the chamber wall spacing by first baffle plate 3 in the above-mentioned hook tail frame, containing cavity 10 that second baffle 5 is formed.In the present embodiment, the plate face width degree of slave plate is less than the chamber wall spacing of the containing cavity of being made up of framework 1 10.
The utility model can be known by Fig. 3 in use, and the pipe link 9 of hitch is perpendicular to the plate face of slave plate 7, and contacts with slave plate 7.Pipe link 9 front ends at hitch offer pipe link spacing hole.Draft key 8 passes draft key mounting hole 2 and pipe link spacing hole simultaneously and carries out spacing to the pipe link 9 of hitch.Need to prove; The equal diameters of the aperture of pipe link spacing hole and draft key 8; The aperture of draft key mounting hole 2 is greater than the diameter of draft key 8, and the difference outer face that equals energy disperser 6 is to the distance of the wall outer end, chamber of the containing cavity 10 that is formed by first baffle plate 3, second baffle 5.
When traction, tractive force passes to hook tail frame by the pipe link 9 of hitch through draft key 8, and by aft end face 4 compression buffers 6 of hook tail frame, energy disperser 6 passes to slave plate 7 with tractive force more again, and last tractive force is passed to the follower seat on the car body by slave plate 7.Work as glancing impact, braking force passes to slave plate 7 by the pipe link 9 of hitch, and slave plate 7 passes to the aft end face 4 of hook tail frame through compression buffer 6 then, and the aft end face 4 by hook tail frame passes to the follower seat on the car body at last.In the transmittance process of compression buffer 6; When compression reaches certain stroke; Slave plate 7 pushes with the chamber wall of the containing cavity 10 that is formed by first baffle plate 3, second baffle 5 mutually; After this in transmittance process, just do not continuing compression buffer 6, and directly passing to first baffle plate 3 and second baffle 5, forming overload protection by slave plate 7.In transmittance process, this shock absorber has the advantages that rigidity is big, stroke is little, realizes the effect that impulsion is little.
For the effect that makes the utility model is obvious, in the present embodiment, energy disperser 6 is the short travel energy disperser.
It should be noted last that; The above specific embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to instance the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
