Abstract
A kind of 200km/h passenger car bogie, including framework composition, wheel set axle box device, central mounting device, brake rigging, it is characterized by: axle box bearing uses self-sealing bearing, pivoted arm node uses separate structure, the housing interference fit of two valve nodes of left and right, the bottom set rubber metal pad number of plies of air spring increases layer 2-3, and laminated rubber heap internal cavities are wide at the top and narrow at the bottom trapezoidal.Bearing of the present invention has the bearing of sealing structure using itself, and the powder that the fragment and shaft end equipment for avoiding corrosion of wriggling generate enters Bearing inner, ensure that grease cleaning degree；Pivoted arm node uses separate structure, and rubber pre compressed magnitude can increase as needed, provides connection stiffness, it is ensured that vehicle is shaken so that unstability will not occur when the operation of 200km/h speed；Increase the laminated rubber heap number of plies, to increase laminated rubber stack height, reduces rubber metal pad rigidity, increase air spring lateral deflection ability, vehicle will not be leaked out by the small curve space-time gas spring of 80m.
Description
Technical field
The present invention relates to rail vehicle trucks, more particularly, to a kind of 200km/h rail vehicle passenger car bogie.
Background technique
Currently, domestic railway passenger car bogie is mostly speed per hour 160km/h, although EMU overall trip speed has most reached fastly
350km/h, but be the absence of for faster speed railway passenger car bogie development.Existing country's railway passenger car bogie, bearing are equal
Using open type bearing, with the raising of running velocity, the friction of Bearing inner is increased accordingly, the cleannes drop of grease
Low, former open type bearing has been unable to satisfy the needs of the change speed of service.Simultaneously as axle box nodes rigidity is smaller, bogie faces
Boundary's speed is less than normal, and running velocity is more than that unstability will occur after 200km/h to shake, and influences vehicle operational safety.In addition existing
The Chinese yeast capsule air spring that bogie uses, lateral deflection ability is limited, can only meet through 100m curve requirement, if passed through
Curve less than 100m then will lead to air spring and leak out.
Summary of the invention
The object of the present invention is to provide a kind of speed faster, and structure is simple, a little repair, the 200km/h visitor of safety and comfort
Vehicle bogie meets passenger train market for the needs of car speed.
To achieve the above object, the present invention provides a kind of 200km/h passenger car bogie, including framework composition, wheel to axle box
Device, central mounting device, brake rigging, it is characterised in that: axle box bearing uses self-sealing bearing, and pivoted arm node uses
Separate structure, the housing interference fit of two valve nodes of left and right, the bottom set rubber metal pad number of plies of air spring increase layer 2-3, fold
Layer rubber metal pad internal cavities are wide at the top and narrow at the bottom trapezoidal.
The axle box uses labyrinth seal structure, and fitted bearing self seal structure can effectively ensure that bearing grease
Cleannes.
The requirement for meeting every three disk of axis braking there are three flap seat is braked is set on each crossbeam of the framework.
A kind of rail vehicle, including bogie, the bogie are bogie described in above-mentioned any one.
The present invention has sealing structure using itself compared to domestic existing railway passenger car bogie (160km/h), bearing
Bearing, the powder that the fragment and shaft end equipment for avoiding corrosion of wriggling generate enter Bearing inner, ensure that grease cleaning degree；Turn
Arm joint point uses separate structure, and rubber pre compressed magnitude can increase as needed, provides connection stiffness, it is ensured that vehicle is with 200km/
Unstability shaking will not occur when running for h speed；Increase the laminated rubber heap number of plies, to increase laminated rubber stack height, reduces rubber
Glue heap rigidity increases air spring lateral deflection ability, and vehicle will not be leaked out by the small curve space-time gas spring of 80m.

Specific embodiment
- Fig. 5 referring to Fig.1, the specific embodiment of the invention include framework composition 1, wheel set axle box device 2, central mounting dress
Set 3, brake rigging 4.Framework composition be the basis for assemble other each components, set on each crossbeam there are three brake hanging
Seat meets the requirement of every three disk of axis braking.The rolling movement of wheel is converted to the horizontal of bogie and transported by wheel set axle box device 2
Dynamic, shock and vibration of the simultaneous buffering from track, axle box bearing uses circular cone self-sealing bearing, and Bearing outer axle box uses two
Body formula structure is made of pivoted arm 9 and hoop 10, and pivoted arm node 11 uses separate structure, and node is divided into left and right two parts 12,13, left
Right two-part housing 14 using being pressed into together by the way of being interference fitted, make 15 pre compressed magnitude of filled rubber can as needed into
Row adjustment guarantees vehicle critical speed with higher to realize the longitudinal proportion with lateral stiffness of node.Axle box is using fan
Palace sealing structure 16, fitted bearing self seal structure, double-layer seal can effectively ensure that the cleannes of bearing grease.
Central mounting device 3 transmits tractive force and brake force between car body and bogie by drawing pull bar, passes through sky
Gas spring 6 provides the vertical support and damping of car body, and 17 number of plies of air spring laminated rubber heap increases to 6 layers, and height is also corresponding
Increase increase air spring lateral deflection ability to reduce lateral stiffness, air spring enable to pass through
The small curve of 80m is without leaking out.Anti-hunting damper holder 7 is increased to 2500kN.s/m by 250kN.s/m using damped coefficient, simultaneously will
Unloading rate is reduced to the friction-type damper of 0.004m/s by 0.04m/s, effectively inhibits the hunting of vehicle, improves vehicle
Critical speed.
Brake force needed for brake rigging 4 provides vehicle, three brake discs 5 of every axis guarantee when vehicle high-speed is run
Stopping power.
