Description
Technical field
The present invention relates to bogies for railway vehicles field, more particularly to a kind of bogie of anti-diamonding.
Background technology
Bogie is the critical component of rolling stock, is directly connected to vehicle operation stability and security.Early stage railway
Vehicle mainly uses three-piece bogie, mainly by take turns to, side frame, bolster, central mounting device and brake apparatus form.
Railway car wheel tread has certain taper, and track also inevitably has various irregularities so that car
In the process of running, take turns to producing hunting.The frequency of taking turns in S motion can carry with the raising of running velocity
Height, if Vehicular system can not effectively suppress the hunting of wheel pair, intact stability can be caused drastically to decline, can further caused
The driving accidents such as vehicle derailing.
The suppression that common three piece truck moves to taking turns in S rely primarily on bolster, side frame, central mounting device it
Between relative rotation resistance（As bogie diamond resistant rigidity）, but when running velocity is more than 70km/m, common three-major-items
The diamond resistant rigidity of bogie just can not effectively suppress the hunting of wheel pair, and this obviously can not meet growing railway fortune
Defeated demand.
Therefore, the later stage is by using bogie cross-braced device（Side frame is connected using two cross one another bars
Come）, effectively increase the anti-diamonding ability of bogie so that vehicle possesses 120km/h service abilities.It is existing to intersect branch
Support bogie is divided into lower cross-braced bogie bogie and middle cross-braced bogie again by the position of crossbar.But cross support
Bogie has many limitations to bulk, mode of braking, bolster and side cage structure, causes technology and technologic limitation
Property.Therefore, a kind of performance of necessary design it is identical with above-mentioned bogie and by the small bogie of boundary condition limitation, to fit
Country variant customer demand is answered, reduces Corporation R ＆ D and management cost.
Existent technique scheme one：Crossbar is arranged in below bolster by lower cross-braced bogie bogie in interleaved mode.
Because circuit bottom gauge and space limit, pull bar mode of braking during brakes will use, this mode of braking
When vehicle is implemented to brake, vehicle body braking tie rod is needed across bolster, therefore brake lever must be provided with one with the vertical plane of symmetry
Determine drift angle（Slash bar）, cartridge is avoided, therefore lever needs bending to handle, and can so have additional lateral power to brakes, make
Brakes is inclined to bogie side and causes certain flange wear；Lever after bending is when implementation braking rotates, meeting
Cause the additional friction resistance of connecting portion, influence vehicle retardation efficiency, and the abrasion of connecting portion can be increased；In addition, shake
Bracket is set on pillow, prevents car body tie rod from producing abrasion with bolster top surface.
Because lower space limits, two crossbar intersection positions, rod member middle part must take die mould to handle, and avoid two
Crossbar is interfered, and positioning need to be attached with buckle, elastic component, is improved crossbar self-strength, is avoided two bar phases
Mutually abrasion；Crossbar will carry out die mould processing with a watt support junction, the body of rod, avoid crossbar and watt support interference, an abrasion；Crossbar
Both ends need to be threaded hole, to be connected with side frame；Side frame bottom sets support base, to be connected with crossbar.
Further, since crossbar and rail apart from small, load and unload scene in mineral, easily extruded by the mineral being scattered on circuit
And deform, cause runnability to decline, increase maintenance, repair cost.
The shortcomings that prior art one：
Shortcoming one：Limited greatly by space, it is desirable to there is sufficiently large bottom space and inflexible wheel base to arrange.
Shortcoming two：It is big to mode of braking limitation, increase brake component manufacturing process difficulty and brakes internal drag, drop
Low vehicle retardation efficiency, increase manufacture and maintenance cost.
Shortcoming three：Crossbar manufacture difficulty is big.
Shortcoming four：Connector is more between crossbar and between side frame, system complex, and manufacturing cost is high.
Shortcoming five：Crossbar connecting support seat is welded on side frame, and dimensional accuracy ensures that difficulty is big, adds and is manufactured into
This.
Shortcoming six：In cargo handling place, easily acted on and deformed by the goods that is scattered on circuit.
Existent technique scheme two：
Crossbar is passed through bolster by middle cross-braced bogie, is arranged in interleaved mode in the middle part of bogie.
Middle cross-braced bogie will use lower pull bar mode of braking because middle part is provided with cross-braced device, should
Brake apparatus brake lever uses straight lever or slash bar mode according to customer habits and demand.
Because vertical space limits, two crossbar intersection positions, rod member middle part must take die mould to handle, and avoid two
Crossbar interferes；Crossbar will set bending with a watt support junction, the body of rod, avoid crossbar and watt support interference, an abrasion；Side
Support base is set on the outside of frame, to be connected with crossbar.
Because crossbar needs to pass through in the middle part of bolster, need to set large area through hole in the middle part of bolster, significantly weaken and shake
Rest the head on intensity, it has to made up by the way of the internal structure of complexity and increase wall thickness, add design, manufacturing process difficulty
And product weight so that design, manufacturing cost rise, the effective freight volume of vehicle reduce.Crossbar will pass through side frame, offside simultaneously
Frame structure also result in certain limitation.
The shortcomings that existent technique scheme two：
Shortcoming one：Limited greatly by space, it is desirable to there is sufficiently large vertical space and inflexible wheel base to arrange.
Shortcoming two：There is certain limitation to mode of braking.
Shortcoming three：Crossbar is complicated, and connector is more between side frame, and cost is high.
Shortcoming four：Crossbar connecting support seat is welded on side frame, and dimensional accuracy ensures that difficulty is big, improves and is manufactured into
This.
Shortcoming five：Big to side frame, the limitation of bolster structure, bolster manufacturing process difficulty is big, cost is high.
