Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in Fig. 1-Fig. 7, the utility model discloses a kind of novel buffer for rolling stock, including from plate
(1), caging bolt (2), nut (3), flexible member (4)；
Be two pieces from the quantity of plate, before being respectively from plate and after from plate (it is convenient in order to describe by taking Fig. 1 as an example, Fig. 1 is left
Being defined as from plate for side is preceding right from plate from plate, being defined as from plate for right side；Naturally, flexible member is from the one side of plate close to preceding
For front side or above；)；The quantity of flexible member is N, and N >=2；All elastic element (4) forms bullet after being stacked
Property body；Elastomer is monosymmetric to set two pieces to set one piece from plate from plate (1), that is, elastomer side；From the four of plate (1)
Angle offers through hole, and four caging bolts are tightened after being each passed through two pieces of through holes from plate with nut (3)；So that flexible member
(4) compressed, produce certain pretightning force；Buffer according to amount of capacity, can adjust the quantity of flexible member (4).
The specification of four caging bolts is identical, and the centre of the caging bolt (2) is cylindrical bar, and one end is more straight than cylindrical bar
The small screw rod in footpath, the other end are equilateral six prism bigger than cylinder shank diameter (equilateral six prism is the nut of caging bolt)；
The nut is assembled on the screw rod；Nut on the screw rod of each caging bolt to tighten range position as designed
The length of screw rod；
The peripheral sulfidization molding rubber (4.1) of steel plate (4.2) forms the flexible member (4) afterwards；The flexible member (4)
Each arrangement one boss (4.3) and blind hole (4.4) of front side upper and lower ends, the relevant position of the rear side upper and lower ends of flexible member
Respectively one blind hole (4.4) of arrangement and boss (4.3)；In two adjacent flexible members, the boss insertion of a flexible member is another
In the blind hole of one flexible member.When being overlapped mutually, boss (4.3) insertion blind hole (4.4) realizes positioning.The horizontal stroke of blind hole and boss
Section is typically both designed as circle.
Preferably, as shown in Fig. 2, Fig. 3 and Fig. 7：The corner of flexible member (4) is provided for the breach stepped down；For allowing
The breach of position can allow caging bolt smoothly to pass through flexible member, not influence the elastic space of flexible member；The elasticity member
The close top and bottom position of part front side surface and rear side surface is respectively arranged with groove, the width of the notch of groove to bottom land
It is gradually reduced.The structure of groove formed "<" type and ">" type, this structure causes elastic more preferable.
Preferably, as shown in Figure 7：Thickness of the flexible member close to the position at four edges is gradually reduced；Edge is thick
Degree reduction helps to lift compression stroke.
Preferably, as shown in Figure 1 and Figure 4：It is quadrangle ledge structure (four sides of indent of indent from the corner of plate (1)
Shape ledge structure removes the small cuboid of one as shown in Figure 1 and Figure 4, similar to four clipped corners in rectangular parallelepiped structure, small rectangular
The thickness of body is less than from plate thickness, therefore, forms four and allows bit space), open up on step surface for through caging bolt
Through hole, the through hole cross sectional shape are circle.Such a ledge structure, one can be formed and allow bit space.Ensure that caging bolt (2) is worn
After entering, the nut portion of caging bolt, nut, screw end head, which can be located at, to be allowed in bit space；It will not be collided with couple yoke.
The a series of tool described in detail only for feasibility embodiment of the present utility model of those listed above
Body illustrates that they are simultaneously not used to limit the scope of protection of the utility model, all to be made without departing from the utility model skill spirit
