Description
Technical field
The invention belongs to coupler draft gear guideway vehicle hitch energy disperser, particularly a kind of novel city rail subway is used the tightlock coupler buffer structure.
Technical background
The development City Rail Transit System has become the only way that China solves urban transport problems; The industrialization of urban rail transit vehicles is one of important process of China's rolling stock industry; And the production domesticization of city rail vehicle key components and parts is the important assurance of urban rail transit vehicles industrialization, and tight lock coupler and energy disperser that development is fit to China's city railway vehicle have crucial economy and strategic importance.Tight lock coupler and energy disperser are to integrate electronic product mechanical, electrical, gas, no matter are all to have very big difficulty in the research and development of product design, manufacturing, material and test setup.
Vehicle connect to be hung, and starts traction, cruising, generation pressure that all can be on hitch in the braking procedure.Tightlock coupler can be eliminated the free clearance that connects extension between the vehicle, effectively reduces longitudinal impulse, improves the stationarity of train operation.The effect of energy disperser is to relax car impact, reduces the longitudinal direction of car impulsion.The quality of its performance directly influences traffic safety and degree of passenger comfort.The design adopts the clay core body as endergonic main device, utilizes the compression clay to do work and absorbs external energy, guarantees the running stability of urban light rail, railcar.
Elastic cement buffer is European in recent years a kind of novel buffer newly developed, on French, German, Polish high speed train, passenger vehicle and lorry, uses and succeeds, and has been included in UIC standard (UIC526-1 at present; UIC526-3).Domestic research and use to elastic cement starts from nineteen nineties; The elastic cement snubber of main production low capacity; Its application is relatively limited, and the high power capacity elastic cement research that can be used for aspects such as guideway vehicle is at the early-stage, and technology is still immature.Elastic cement buffer is compared advantages such as having capacity is big, resistance is little, volume is little, light weight, period of inspection and repair length with the ordinary buffer device, under same capacity, can alleviate 30%～50% weight, and the period of inspection and repair reaches 10a.Along with the development of urban rail transit in China and the raising of degree of passenger comfort requirement, elastic cement buffer will be widely used.
" TB/T3143-2006 railroad coach tight lock coupler shock absorber " standard code is all satisfied in design-calculated tight lock coupler installation requirement, designing requirement.Its major technique condition is following:
1) the whole quiet bad load of pulling open of tight lock coupler coupler buffering device should be less than 1200kN, and the maximum load that the normal utilization of trouble free can be born is not less than 600kN.
2) the design-calculated tight lock coupler is mainly used in, and satisfied maximum is no more than the coupling speed of 5km/h, and the running velocity F-Zero is the rail railcar in 80km/h to 120km/h city.
3) the environment for use temperature of elastic cement core body is-20 ℃～+ 40 ℃, and does not influence performance demands after satisfying defrozing silo+110 ℃ insulation answer in 3 hours normal temperature.
4) buffer capacity is greater than 30KJ
5) energy disperser range 73mm
6) rate of energy absorbed by draft gear is greater than 80%
Summary of the invention
The purpose of this invention is to provide a novel city rail subway and use the tightlock coupler buffer structure.It meets " TB/T3143-2006 railroad coach tight lock coupler shock absorber " standard code.Satisfy the operating needs of novel city rail subway with the tightlock coupler energy disperser.

Characteristics of the present invention and advantage:
This novel city rail subway meets " TB/T3143-2006 railroad coach tight lock coupler shock absorber " standard code with the tightlock coupler buffer structure.Satisfy the operating needs of novel city rail subway with the tightlock coupler energy disperser.Of a tightly knit structure, impact resistance is strong.Conservative factor is big, and the life-span is long, and is durable in use.
Description of drawings
Fig. 1 is that novel city rail subway is with tightlock coupler buffer structure cutaway view.
Among the figure: 1) energy disperser outer sleeve; 2) inner sleeve bonnet; 3) bolt M14; 4) packing ring; 5) energy disperser inner sleeve; 6) clay core body; 7) sliding shoe; 8) outer back-up ring; 9) linkage section packing ring 11 bolt M1610)).
The specific embodiment
A novel city rail subway as shown in the figure is used the tightlock coupler buffer structure; The energy disperser inner sleeve is housed in the energy disperser outer sleeve, and energy disperser inner sleeve left end is equipped with the inner sleeve bonnet, and the clay core body is housed in the energy disperser inner sleeve; In the energy disperser outer sleeve, sliding shoe is arranged on the energy disperser inner sleeve right side that the clay core body is housed; The energy disperser outer sleeve end on sliding shoe right side connects outer back-up ring, and the sliding shoe right side connects linkage section, and linkage section passes the centre hole of outer back-up ring.
This newly-designed city rail vehicle mainly is made up of following 11 parts with the tight lock coupler buffer device:
Each tight lock coupler energy disperser all is made up of above-mentioned 11 parts and appurtenances thereof, as shown is the shock absorber constructional drawing.
The motion endergonic process:
Energy disperser is receiving under the external tensile force situation, and 1 energy disperser outer sleeve left end receives bearing pin and fixes, and 11 linkage sections move right.11 linkage sections connect 5 energy disperser inner sleeve right-hand members by flange, and 2 inner sleeve bonnets lean on bolted connection 5 energy disperser inner sleeve left ends, and power is passed to the bottom of 6 clay core bodys, and 6 clay core body right-hand member piston rods withstand 7 sliding shoes, and piston motion absorbs energy.And 7 sliding shoes, two ends are withstood by 8 outer back-up rings, have guaranteed under pulled condition, to have only 5 energy disperser inner sleeves and 11 linkage sections to move right.
Energy disperser is under the pressurized situation, and 1 energy disperser outer sleeve left end receives bearing pin and fixes, and 11 linkage sections are to left movement.11 linkage sections are given 7 sliding shoes with transmission of pressure, and 7 sliding shoes are with the piston of transmission of pressure to 6 clay core bodys, can not move in the core body bottom, absorb outside energy thereby the Piston Compression motion takes place.
Energy disperser assembling order
Should earlier sequence number 11 linkage sections be pierced into from the bottom of sequence number 5 energy disperser inner sleeves during assembling, again the side of sequence number 7 sliding shoes from sequence number 5 energy disperser inner sleeves penetrated, again sequence number 6 clay core bodys penetrated in the sequence number 5 energy disperser inner sleeves.
During assembling, following contact surface sequence number 11 linkage sections and sequence number 5 energy disperser inner sleeves have been guaranteed, sequence number 11 linkage sections and sequence number 7 sliding shoes; The sequence number of packing into 2 inner sleeve bonnets, bolt together is fixed on sequence number 2 inner sleeve bonnets on the sequence number 5 energy disperser inner sleeves, and making sequence number 7 sliding shoes and sequence number 6 clay core body gaps is zero.The 5 energy disperser inner sleeves that assemble, 7 sliding shoes, 6 clay core bodys, 11 linkage sections are put into 1 energy disperser outer sleeve, at last 8 outer back-up rings are fixed by bolts on the 1 energy disperser outer sleeve.
