As shown in Figure 1, the utility model provides a kind of shock absorber, comprises couple yoke 2, two groups of centering push rods 5, ball ring 3 and buffer structures 4,
Hitch 1 is connected with couple yoke 2, the relative both sides of described hitch 1 afterbody are respectively arranged with convex shoulder, described ball ring 3 and buffer structure 4 are all placed in described couple yoke 2, and the front end of described couple yoke 2, described ball ring 3, the front end of described buffer structure 4 is affixed setting successively, the front end face of described buffer structure 4 is the arcwall face of indent, and the spherical of described ball ring 3 coordinates with described arcwall face and is affixed, described ball ring 3 and described arcwall face can relative slidings, centering push rod 5 described in two groups is all located in the front end of described couple yoke 2, and two groups of centering push rods 5 are corresponding with two described convex shoulders respectively arranges, first end and the ball ring 3 of often organizing centering push rod 5 offset, second end is used for and corresponding shoulder contact effect.
Wherein, in the utility model embodiment, whole shock absorber is all horizontally disposed with, and two ends connect two vehicles respectively, and the axis of ball ring 3 is all in level; Hitch 1 is generally arranged on the left end of couple yoke 2, the front end namely in the present embodiment;
As shown in Figures 2 and 3, the shock absorber that the purpose of this utility model is to provide, deflect between adjacent two cars, first hitch 1 deflects, the convex shoulder of hitch 1 afterbody side is together deflected, thus the centering push rod 5 of contact correspondence position, this centering push rod 5 is moved to the right, and push ball ring 3, arcwall face can be against while ball ring 3 is boosted deflect to opposite side, buffer structure 4 then together can not produce deflection with ball ring 3, it can motion of translation to the right, the thrust passed over by ball ring 3 is so made still to be dispersed in uniformly on whole arcwall face, thus ensure whole buffer structure 4 uniform force, improve reliability of the present utility model, and then effectively improve the safety of rolling stock operation, reduce the probability that derail accident occurs, counter motion, then as a same reason.
As shown in Figure 1, as preferably, in the utility model embodiment, described buffer structure 4 comprises front apron 41, the first combined elastic body 42, middle baffle plate 43, second combined elastic body 44, the back shield 45 that arrange in turn, between described front apron 41 with described middle baffle plate 43, described middle baffle plate 43 is connected respectively by fitting-up bolt 6 with between described back shield 45, the front end face of described front apron 41 is the arcwall face of described indent, and described arcwall face coordinates with the spherical of described ball ring 3 and is affixed.
As shown in Figure 1, also can see Fig. 4, as preferably, described first combined elastic body 42 includes multiple resilient rings 421 and multiple spring 422 with described second combined elastic body 44, and multiple resilient rings 421 are alternately arranged successively with multiple spring 422.
Wherein, spring 422 is preferably High molecular material spring 422, resilient ring 421 is the cup lid-like made with elastomeric material, through hole is offered in the middle part of it, multiple resilient ring 421 is alternately arranged successively with multiple spring 422, each resilient ring 421 detains a spring 422, as shown in Figure 4, the first half is spring 422 and resilient ring 421 normal condition, the latter half is compressive state, after spring 422 compresses certain stroke, adjacent resilient ring 421 contacts with each other, extruding, and circumferencial direction (marginal portion of bowl cover) elastic deformation, general dilatating and deformable laterally, and increase with its deflection of increase of length of contact and deformation force, therefore Absorbable rod partial buffer power, by adjusting the angle (i.e. the angle of the marginal portion of bowl cover) of buffering ring, the size absorbing cushion effect can be adjusted, thus ensure the impulsive force that resilient ring 421 and spring 422 shared hitch 1 transmit, increase load-carrying capacity.
As shown in Figure 1, as preferably, described buffer structure 4 also comprises combined elastic body guide rod 7, described combined elastic body guide rod 7 successively through the resilient ring 421 of front apron 41, described first combined elastic body 42 and the resilient ring 421 of spring 422, described middle baffle plate 43, described second combined elastic body 44 and spring 422, described back shield 45, and is fixedly connected with back shield 45.Combined elastic body guide rod 7 can limit the length of whole buffer structure 4, and ensures that resilient ring 421 and spring 422 are in middle part correct position.
As shown in Figure 1, as preferably, described front apron 41 is provided with counter sink 8, the head of described combined elastic body guide rod 7 is arranged in described counter sink 8.
As shown in Figure 1, as preferably, described fitting-up bolt 6 is T-shaped bolt, described front apron 41 is provided with T-slot 91, described back shield 45 is provided with stepped hole 92, and two described T-shaped bolts are each passed through corresponding T-slot 91 and stepped hole 92, and are all connected with described middle baffle plate 43.
In the utility model embodiment, ball ring 3 and buffer structure 4 are all spacing by couple yoke 2, and when hitch 1 stretches to the left, couple yoke 2 promotes back shield 45 and moves to the left, and the spring 422 in compression between baffle plate 43, back shield 45 cushions; Back shield 45 right flank is spacing by couple yoke 2, and when hitch 1 moves to the right, couple yoke 2 promotes ball ring 3, front apron 41, middle baffle plate 43 move right, and compresses two groups of springs 422 and cushions.Therefore hitch 1 compresses one times that cushion stroke is stretching cushion stroke.Hitch 1 is spacing by centering push rod 5, centered by bearing pin, swing up and down certain angle.This side centering push rod 5 is pressed, push rod pressure ball ring 3 when hitch 1 swings aside.Can move to opposite side while ball ring 3 is boosted, to keep fitting with spheric seating, and front apron 41 does motion of translation to the right and can not produce inclination, thus ensures spring 422 uniform force.
