Description
Technical field
The present invention relates to a kind of bogie, particularly relates to a kind of quick railway goods train bogie.
Background technology
A critical component of the bogie of car as rail vehicle whole, it carries loading carriage above each several part weight
Measure, ensure that vehicle passes through the task of curve, be the main achievement unit of vehicle safety in operation, stationarity and stability indicator
The speed of service and bearing capacity of part, i.e. rail vehicle itself are mainly determined by the performance of bogie.Domestic and international railway goods at present
Car bogie has two kinds of fundamental types, and one kind is traditional three-piece bogie, and another kind is welding frame type bogie.Tradition
Roller bearing adapter stabilizer bar mostly employs three-piece bogie structure, (removes as turned 8 series, turning K series bogie and turns K3 bogies
Outside), but because three-piece bogie diamond resistant rigidity is small, unsprung mass is big and uses single shoe brake mode, therefore
It has critical speed it is relatively low, it is larger to line impairment, braking when wheel thermic load it is big the shortcomings that, the speed of service all without more than
120km/h；Welding frame type bogie is the Typical Representative of the European freight bogie of car, such as French Y25 types, German DB661
With DRRS types, Britain's TF types etc., these bogies adapt to that circuit distortional ability is poor, and highest overall trip speed is also with regard to 160km/h at present.
In recent years, Logistics Market is sent to the ageing high added value goods such as requirement more and more higher, part load container to goods
The rapid of thing transport is railway freight new growth point.Some Railway Car Plants of the country are developing hot-short vehicle turn at present
To frame, maximum speed is also only limitted to 160km/h, and is also not up to the requirement of the practical commercial speed of service.
Therefore, base of the goods stock bogie of 200km/h speed class as railway development hot-short from now on is developed
Plinth, it is the technical research that current those skilled in the art of the present technique are urgently carried out.
The content of the invention
The technical problems to be solved by the invention are：A kind of quick railway goods train bogie is provided, the bogie reduces

With lower metal support, the upper metal support from top to bottom includes upper central tube portion, upper arc connecting portion and upper mounting cylinder
Portion, the upper metal support is into inverted funnel-form；The inner hole sleeve of the upper rubber support ring is mounted in the upper central tube portion
On, the periphery of the upper rubber support ring is provided with the circular conical surface being engaged with framework, the lower metal support by upper and
Include lower central tube portion, arc lower connecting portion and lower mounting cylinder portion down, the inner hole sleeve of the lower rubber support ring is under described
In central tube portion, the lower mounting cylinder portion is fixed on axle box, and the lower rubber support ring is arranged in the upper mounting cylinder portion,
The upper metal support and lower metal support are arranged concentrically.
As a kind of preferable scheme, circumference uniform distribution is respectively arranged with the upper metal support and lower metal support
2-4 bar blind slots.
As a kind of preferable scheme, the blind slot in the upper metal support is upwardly extended by the lower end in upper mounting cylinder portion
Supreme arc connecting portion and the intersection in upper central tube portion；Blind slot in the lower metal support by lower mounting cylinder portion lower end
Extend upwardly to the intersection of arc lower connecting portion and lower central tube portion.
As a kind of preferable scheme, the framework into I-shape construction, the framework include two parallel curb girders with
And the sleeper beam between the curb girder is welded in, the lower front end portion of each curb girder and rearward end are respectively arranged with front-wheel to mounting seat
Mounting seat, the periphery of the upper rubber support ring are coordinated mounting seat mounting seat and trailing wheel with front-wheel with trailing wheel, the pillow
The center bearing of sphere contact type is provided with above the middle part of beam, is respectively arranged with the sleeper beam at left and right sides of center bearing
Side damping device.
As a kind of preferable scheme, the side damping device includes collateral seat, two damping springs and upper mounted plate, institute
State upper mounted plate to be installed on collateral seat, described two damping springs are pressed between upper mounted plate and collateral seat in advance, described solid
The friction plate with the frame contact of lorry is fixed with fixed board.
As a kind of preferable scheme, lower friction teeth is provided with below fixed plate, is located on corresponding framework
The matching board coordinated with upper mounted plate is fixed with below upper mounted plate, is provided with above the matching board and is nibbled with lower friction teeth
The upper friction teeth closed.
As a kind of preferable scheme, the brake apparatus includes clamp-type unit of the suspension on the sleeper beam of framework
