Abstract
The invention discloses a kind of power concentration EMUs B0 bogies, including day font framework, wheel to, single traction perch, the truck end sill is provided with framework traction seat, and described single traction perch one end is connected on framework traction seat by the first traction seat, the other end is connected on vehicle body bottom frame by the second traction seat；The height of one end that single traction perch is connected with framework traction seat is less than the height of its one end being connected with vehicle body bottom frame.The present invention sets low the oblique simplex pull rod hitch structure in position in using, realize the low level traction of small-wheel-diameter bogie, greatly improve adhesion availability, reduce axle weight transfer, and pass through the optimization to the position relationship of parts on bogie so that power car has excellent comfortableness, stationarity, security.Both both wired 160km/h velocity stages had been met, the requirement of security, stationarity and low wheel-rail dynamic interaction when meeting the operation of Line for Passenger Transportation 200km/h velocity stages again.
Description
Technical field
The invention belongs to technology of track traffic, and in particular to a kind of power concentration EMUs B0 bogies.
Background technology
The country has basically formed CRH1, CRH2, CRH5, CRH3 high ferro power by import, digestion and absorption several years ago at present
Scattered EMUs pedigree, speed class cover 200km/h~350km/h substantially.
In order to complete product to locomotive, comprehensive covering of urban rail, EMUs, meet the need of domestic and international Development of High Speed Railway
Will.Researched and developed on the basis of the 160km/h power concentration EMUs developed at present in strict accordance with domestic standard EMUs temporary provisions
Highest overall trip speed is 200km/h, using the B0 bogies of small-wheel-diameter.
Original power concentration EMUs are primarily present following defect：
1. draw-gear uses horizontally tracting bar structure, its nominal drawbar height reaches 380mm, and adhesion availability is low, axle weight
Transfer is big, and dynamic performance is poor.
2. both wired 160km/h velocity stages and Line for Passenger Transportation 200km/h velocity stages safety in operation, steady can not be met
Property, low wheel-rail dynamic interaction requirement.
In addition, being defined to the direction vocabulary being previously mentioned in this case, in track vehicular field, technical staff generally recognizes
Fixed direction has three kinds：
It is vertical：Vertically perpendicular to the direction of rail level.
Longitudinal direction：Along the direction of track.
Laterally：Horizontal vertical is in the direction of track.
The content of the invention
In view of the above-mentioned problems, the present invention is intended to provide one kind disclosure satisfy that both wired 160km/h velocity stages and Line for Passenger Transportation
200km/h velocity stages safety in operation, stationarity, the good power concentration EMUs B0 bogies of dynamic performance.
The technical scheme of the present invention that solves the problems, such as is：A kind of power concentration EMUs B0 bogies, including day font structure
Frame, wheel are provided with framework traction seat to, single traction perch, the truck end sill, and described single traction perch one end passes through the first traction seat
It is connected on framework traction seat, the other end is connected on vehicle body bottom frame by the second traction seat；
The height of one end that single traction perch is connected with framework traction seat is less than the height of its one end being connected with vehicle body bottom frame.
Further, the wheel diameter of the wheel pair is 1050mm, the extended line and framework of the axis of the single traction perch
The intersection point A of center line is 60mm apart from the height of rail level.
In such scheme, using push-pull type low level single traction perch, the traction of bogie end oblique pull, greatly improve and stick together
Utilization rate, reduce axle weight transfer.
Further, in addition to the secondary spring that is arranged on truck side sill, two are interval with every truck side sill
Secondary spring, the midpoint between the secondary spring of homonymy are respectively a and b, and a and b line are center line X；
The horizontal geometric center lines of framework are that Y, X and Y are biased in a longitudinal direction.
The purpose of biasing is to can be used in balancing each axle axle weight, and specific offset or dish is needed according to framework, wheel to driving
Configuration with axle is calculated, by that can be balanced the heavy optimal set-up mode of each axle axle to configuring and calculating.
And two anti-snakes further, in addition to two anti-hunting damper holders being respectively arranged on two truck side sills,
Midpoint Central Symmetry of the row shock absorber on truck transom, the anti-hunting damper holder are variable damping shock absorber.
What is used in the past is all to determine damping shock absorber, is adapted to friction speed level not using variable damping shock absorber here
Same damping requirements.
Also include being respectively arranged on two truck end sills two two are lateral damper, are respectively arranged at two frameworks
The two of curb girder center position are vertical damper；
Two be lateral damper axis it is parallel with truck end sill, and two two are midpoint of the lateral damper on truck transom
Central Symmetry.
By to said structure, arrangement and parameter optimization so that power car has excellent comfortableness, stationarity.
Preferably, in addition to anti-dropout steel wire rope, described anti-dropout steel wire rope one end is connected with vehicle body bottom frame, the other end with
The shaft connection of single traction perch.
The present invention remarkable result be：
1. setting low the oblique simplex pull rod hitch structure in position in using, the low level traction of small-wheel-diameter bogie is realized, is greatly improved
Adhesion availability, axle weight transfer is reduced, dynamic performance is good.
2. being biased in a longitudinal direction by center line X and Y, each axle axle weight can be balanced, ensures traveling comfort.
3. the optimization of the position relationship of parts on pair bogie so that power car has excellent comfortableness, stationarity.
Both both wired 160km/h velocity stages had been met, it is security when meeting the operation of Line for Passenger Transportation 200km/h velocity stages again, steady
The requirement of property and low wheel-rail dynamic interaction.
