The elastic wedge is characterized by comprising a wedge body, an elastic body, a primary friction ball seat, a primary friction block and a secondary friction block, wherein the elastic body is formed by vulcanizing a plurality of rubber elastic blocks and steel plates which are arranged at intervals; the primary friction ball seat comprises a cylindrical steel substrate; the outer surface of the steel substrate is provided with an annular groove; a concave spherical surface is formed at one end of the steel substrate; the concave spherical surface is provided with a through pin hole in a radial direction; the primary friction block comprises a steel convex spherical surface matched with the concave spherical surface and an abrasion-resistant block; the bottom part of the convex spherical surface is connected with the abrasion-resistant block through a dovetail groove; the convex spherical surface is provided with a pin hole corresponding to the pin hole on the primary friction ball seat; the two pin holes are connected integrally through a connecting pin; and an annular guide sleeve for sealing the connecting pin and provided with an opening is arranged in the annular groove. The elastic wedge can be widely applied to railway wagon bogie frames.
Description
Technical field
The utility model relates to a kind of railway truck elasticity wedge, particularly about a kind of elasticity wedge that is used for railway goods train bogie.
Background technology
The axle box damper mechanism of general railway goods train bogie not only can also be controlled the right located lateral rigidity of railway truck wheel for railway truck provides vertical vibration damping.Continuous speed-raising along with railway truck; Change has also taken place in the structure of bogie truck; The existing railway truck framework type bogie truck that uses generally adopts and becomes friction-type wedge damper mechanism, becomes rigid construction wedge or the low elasticity wedge of rigidity that mostly the wedge of friction-type wedge damper mechanism is made into whole cast iron, cast steel.There is the wheel defective big to located lateral rigidity in the rigid construction wedge.As shown in Figure 7; Existing elasticity wedge is arranged on two elasticity wedges 91 both sides of axle box 92 respectively when using; And be placed on the round spring 93 through the round navel of elasticity wedge 91, the secondary friction shoe of elasticity wedge 91 contacts with truck frame drawing strickle guide inclined-plane (not shown) respectively.The elastic body set inside of existing elasticity wedge 91 has a pin-and-hole, because the existence of pin-and-hole causes elastomeric rigidity setting range little, take turns lowlyer to located lateral rigidity, is not suitable for being used in the great railway truck.
Summary of the invention
To the problems referred to above, the purpose of the utility model provides a kind of elastic body that can make has bigger rigidity setting range and satisfied elasticity wedge of taking turns the railway goods train bogie of located lateral rigidity requirement.
For realizing above-mentioned purpose, the utility model is taked following technical scheme: a kind of elasticity wedge of railway goods train bogie is characterized in that: it comprises a wedge body, an elastic body, main friction ball seat, a main friction shoe and a secondary friction shoe; Said elastic body is formed through sulphurization by caoutchouc elasticity piece and the steel plate that some intervals are provided with; Said main friction ball seat comprises a columniform steel substrate; Said steel substrate outside face is provided with an annular groove; One end of said steel substrate is provided with a concave spherical surface, and said concave spherical surface radially is provided with the pin-and-hole of a perforation; Said main friction shoe comprises the protruding sphere of steel and the wear-resistant block that cooperate with said concave spherical surface; Said protruding sphere bottom is connected with said wear-resistant block through dovetail furrow; Said protruding sphere be provided with one with said main friction ball seat on the cooresponding pin-and-hole of pin-and-hole; The two links into an integrated entity through a connecting pin, is provided with one in the said annular groove and seals said connecting pin and have the annular orienting sleeve of opening.
The utility model is owing to take above technical scheme; It has the following advantages: 1, the utility model is folded in each elastomer block between each steel plate through sulphurization at interval; And then the elastic body that forms a whole; Satisfy the right located lateral rigidity requirement of railway truck wheel, reduce the wheel track power of railway truck wheel to the time when guaranteeing the railway truck high stability, be suitable for use in the great railway truck of axle through curve.2, the inner no pin-and-hole of the elastic body of the utility model exists, and makes elastic body that bigger rigidity setting range can be arranged.The utility model can be widely used in the railway goods train bogie.
