Abstract

The utility model relates to a large capacity buffer which is arranged on a heavy load freight train. The buffer comprises a 17 type forging hook tail frame, a front draft lug, an elastic body unit buffer, a rear draft lug, a 17 type car coupler yoke key, a middle beam, a impact seat and a car coupler assembly; wherein the elastic body unit buffer consists of fifteen elastic body outer rings, fifteen elastic body inner rings and sixteen steel baffle plates, wherein the installation sequence is as follows: one steel baffle plate, one elastic body inner ring and one elastic body outer ring are sequentially arranged, the elastic body outer ring is positioned outside the elastic body inner ring, the installation method is sequentially carried out in a circulation way, and finally, the last steel baffle plate is installed; the elastic body unit buffer is arranged inside the middle beam; the front draft lug and the rear draft lug are respectively installed at the left and the right ends of the elastic body unit buffer; the 17 type car coupler yoke key is connected with the 17 type forging hook tail frame by the elastic body unit buffer; the impact seat is arranged on the middle beam; andthe right end of the 17 type car coupler yoke key is connected with the car coupler assembly which bears against the rear draft lug. The large capacity buffer has the advantages of being large in capacity and applied to heavy load vehicles.

Description

The high capacity energy disperser

Technical field:

The invention is the energy disperser that is contained on the Heavy Haul Freight Train.

Background technology:

The buffer capacity that existing freight train is installed out of reach overall trip speed 100km/h and Gross Train Weight is the demand of 20000t heavy haul train.

Summary of the invention:

The purpose of the invention provides a kind of high capacity energy disperser that satisfies heavy haul train high capacity demand; The purpose of the invention is to realize by following technical scheme: the high capacity energy disperser is characterized in that being made up of 17 type forging hook tail frames, front draft lug, elastomer unit energy disperser, rear draft lug, 17 type hitch draft keys, central sill, striker and hitch and constitutes; The elastomer unit energy disperser is made up of 15 elastic body outer rings, 15 elastic body inner rings and 16 steel diaphragms; Steel diaphragm, elastic body outer ring and elastic body inner ring sequence of erection are steel diaphragms, an elastic body inner ring, and an elastic body outer ring, elastic body outer ring are contained in elastic body inner ring outside, and a steel diaphragm is adorned in circulation at last successively; The elastomer unit energy disperser is contained in the central sill, elastomer unit energy disperser left end dress front draft lug, right-hand member dress rear draft lug, 17 type hitch draft keys connect 17 type forging hook tail frames through the elastomer unit energy disperser, striker is contained on the termination of central sill, 17 type hitch draft key right-hand members connect hitch and form, and the hitch composition withstands rear draft lug.

The advantage of the invention: adopt the elastomer unit energy disperser can obtain energy disperser capacious, be installed on the heavy haul train and can reduce maximum coupler force, the reduction of maximum coupler force can significantly reduce the impact failure of goods and the probability that coupler buffering device is tired so that the hook that breaks destroys of vehicle;

Among the figure: 1,17 type forging hook tail frames 2, front draft lug 3, elastomer unit energy disperser 4, rear draft lug 5,17 type hitch draft keys 6, central sill 7, striker 8, hitch composition 21, elastic body outer ring 22, elastic body inner ring 23, steel diaphragm

The specific embodiment:

The high capacity energy disperser is characterized in that being made up of 17 type forging hook tail frames, front draft lug, elastomer unit energy disperser, rear draft lug, 17 type hitch draft keys, central sill, striker and hitch and constitutes; The elastomer unit energy disperser is made up of 15 elastic body outer rings, 15 elastic body inner rings and 16 steel diaphragms; Steel diaphragm, elastic body outer ring and elastic body inner ring sequence of erection are steel diaphragms, an elastic body inner ring, and an elastic body outer ring, elastic body outer ring are contained in elastic body inner ring outside, and a steel diaphragm is adorned in circulation at last successively; The elastomer unit energy disperser is contained in the central sill, elastomer unit energy disperser left end dress front draft lug, right-hand member dress rear draft lug, 17 type hitch draft keys connect 17 type forging hook tail frames through the elastomer unit energy disperser, striker is contained on the termination of central sill, 17 type hitch draft key right-hand members connect hitch and form, and the hitch composition withstands rear draft lug.

Elastic body outer ring and elastic body inner ring, central sill, 17 type forging hook tail frames, 17 type hitch draft keys, striker and hitch are formed the even prior art that is; Front draft lug, rear draft lug and the welding of Flexible element two ends steel plate reinstall in the 17 type forging hook tail frames, and hitch is connected with 17 type hitch draft keys with 17 type forging hook tail frames, and integral body is packed in the central sill.

Adopt the elastomer unit energy disperser can obtain energy disperser capacious, be installed on the heavy haul train and can reduce maximum coupler force, the reduction of maximum coupler force can significantly reduce the impact failure of goods and the probability that coupler buffering device is tired so that the hook that breaks destroys of vehicle; The elastomer unit velocity of impact is big more, and the resistance of energy disperser also increases thereupon, and capacity is also just big more, and it is strong more that energy disperser can relax the ability of impacting, and this is that the heavy loading locomotive vehicle is needed; The characteristic of elastomer unit energy disperser and spring and rubber draft gear is relatively: when buffer capacity is identical, draft gear travel one regularly, elastomer unit draft gear reaction force at rating travel minimum; When buffer capacity is identical, draft gear reaction force at rating travel one timing, elastomer unit buffer stroke minimum; This is the advantage place of elastomer unit energy disperser just, can obtain bigger buffer capacity with less resistance and stroke.
