Abstract
The invention discloses a high-power locomotive buffer. The high-power locomotive buffer is provided with a coupler yoke, wherein a front buffer plug, a front cluster plate, an annular spring set, a rear cluster plate and a rear buffer plug are arranged in the coupler yoke in sequence, so that an integrated structure of the buffer is formed, and the annular spring set is formed by sequentially connecting a front cover, a front semicircular spring, an outer annular spring, an inner annular spring, a rear semicircular spring and a rear cover through bolts and nuts. According to the high-power locomotive buffer, a novel buffer device of an annular spring structure is additionally arranged. According to the action principle of buffering of the high-power locomotive buffer, through friction of oblique planes of annular springs, impact kinetic energy is converted into heat energy to be consumed, and thus the buffering function is achieved.
Description
Technical field
The invention belongs to the locomotive buffer being connected to each other, transmitting and relaxing the effect of tractive force for realizing between locomotive and vehicle, particularly a kind of 9600kW of may be used for large power overloading freight locomotive actv. protects the high-power energy disperser that locomotive is without prejudice in the middle part of heavy haul train.
Technical background
Along with the development of China's heavy-haul freight transportation; improve the traction tonnage of locomotive; 2 ten-thousand ton trains adopt 1+1 power decentralized traction protocols, in order to not be damaged when actv. protection locomotive is in the middle part of train, have had higher requirement to the link energy disperser of locomotive.The object developing this product aims at the development of China railways heavy haul transport, along with starting in a large number of China's Datong-Qinhuangdao Railway more than 20,000 tons heavy-load combined trains, the phenomenons such as locomotive energy disperser generation used bolt gets loose, elastic element cracking increase, and the safe and reliable sex chromosome mosaicism of domestic existing locomotive buffer causes the attention of people gradually.
Summary of the invention
The invention provides a kind of energy disperser of cup spring structure, act on the power of couple yoke, by cup spring compression and recuperation in distortion and mutual triboabsorption, thus play mitigation longitudinal impulse effect.Cup spring facing design cone angle is 15 degree, and adopt calcium grease lubrication, its stable friction performance, nerve is good, long service life.The design circular arc of cushion plugs, when bend is crossed by motor supply shop, the cushion plugs jack-up of side, whole energy disperser adjusts recovery automatically, and actv. prevents the phenomenon of derailing from occurring.
Content of the present invention is:
High-power locomotive buffer, is characterized in that: have a couple yoke, is arranged in order front cushion plugs, front clump plate, cup spring group, metaplexus plate and rear cushion plugs in the frame of couple yoke, forms the integrative-structure of energy disperser; The cup spring group that the protecgulum that described cup spring group is connected successively by screw bolt and nut, front semi-ring spring, outer ring spring and inner ring, rear semi-ring spring and bonnet form.
Beneficial effect of the present invention:
This high-power locomotive buffer adopts the energy disperser of cup spring structure, acts on the power of couple yoke, by the distortion of cup spring in compression and recuperation and mutual triboabsorption, thus plays the effect of mitigation longitudinal impulse.Cup spring facing design cone angle is 15 degree, and adopt calcium grease lubrication, its stable friction performance, nerve is good, long service life.The design circular arc of cushion plugs, when bend is crossed by motor supply shop, the cushion plugs jack-up of side, whole energy disperser adjusts recovery automatically, and actv. prevents the phenomenon of derailing from occurring.
This energy disperser adds Novel ring spring structure shock absorber.The action principle of its buffering is the phase mutual friction by cup spring inclined-plane, impact kinetic energy is converted into thermal energy consumption, thus plays the effect of buffering.

In figure: cushion plugs, 6 cushion plugs afterwards before semi-ring spring, 3.6 protecgulums, 3.7 bonnets, 3.8 rear semi-ring springs, 4 metaplexus plates, 5 before 1 couple yoke, 2 front clump plates, 3 cup spring groups, 3.1 bolts, 3.2 nuts, 3.3 outer ring springs, 3.4 inner rings, 3.5.
Specific embodiment
High-power locomotive buffer as shown in Figure 1, 2, has a couple yoke, is arranged in order front cushion plugs, front clump plate, cup spring group, metaplexus plate and rear cushion plugs in the frame of couple yoke, forms the integrative-structure of energy disperser; The cup spring group that the protecgulum that described cup spring group is connected successively by screw bolt and nut, front semi-ring spring, outer ring spring and inner ring, rear semi-ring spring and bonnet form.
Cup spring group is connected to form by bolt 3.1, nut 3.2, outer ring spring 3.3, inner ring 3.4, front semi-ring spring 3.5, protecgulum 3.6, bonnet 3.7, rear semi-ring spring 3.8.
Originally meet the energy disperser of TB/T1961, the groove that design two is circular on front clump plate, ensure that often organizing cup spring is assembled into fixing position, bolt arrangement can ease of assembly.The maximum, force that often group cup spring bears is 1600KN, and the maximum, force that whole energy disperser bears is 3200KN.
This novel energy disperser, meets the regulation of TB/T1961.This buffer buffers medium and couple yoke are structure as a whole, and by 1 couple yoke, clump plate before 1,1 metaplexus plate, 2 cushion plugs, 1 cover cup spring assembles and 1 draft key forms.When energy disperser pressurized, pressure is passed to cushion plugs by draft key, power is passed to front clump plate by energy disperser, and the ring-like spring of front clump plate forced compression, impact kinetic energy is converted into frictional heat energy by the friction of the conical surface and consumes 60% by ring-like spring.
Buffer medium is made up of two groups of ring-like springs, often organizes ring-like spring and is made up of 5 outer shrouds, 4 inner ring, 2 semi-rings; Often organize ring-like spring tools for bolts ' pretension and be convenient to energy disperser assembling.
This energy disperser adds Novel ring spring structure shock absorber.The action principle of its buffering is the phase mutual friction by cup spring inclined-plane, impact kinetic energy is converted into thermal energy consumption, thus plays the effect of buffering.
The action principle of screw coupling
Be used for the effect being connected to each other, transmitting and relaxing tractive force realized between rolling stock.This energy disperser is used for the high-power locomotive that tractive output is greater than 9600KW, its feature is couple yoke, front and back clump plate and shock absorber are integrated, energy disperser medium is ring-like spring structure, and the action principle of draw gear is by the distortion in the compression of cup spring and recuperation and mutual triboabsorption.
When after ring-like spring assembling, bolt and nut play precompressed effect, then after front and back clump plate is loaded couple yoke in the lump, bolt does not stress.When the longitudinal pressurized of hitch, coupler force passes to front clump plate by couple yoke, longitudinal pressure is passed to cup spring composition by front clump plate, ring spring pressurized produces radial distortion, inner ring and outer shroud slide along conical-surface friction, the change of its axial location is longitudinal travel, and the kinetic energy of longitudinal impact is converted to frictional heat energy and elastic deformation energy, thus plays the effect of buffering.After external force is cancelled, the elastic deformation energy of ring spring store, makes cup spring group return to initial position.
This high-power locomotive buffer meets TB/T1961 standard, and this product is applicable to the locomotive of tractive output at more than 9600KW.
