Description
Technical field
The present invention relates to a kind of eight axle rolling stocks, such as the design of dumper.
Background technology
Known eight axles dumper is equipped with the axle of 18-101 types four of Uralvagonzavod (Ural railway plant) productions
Bogie, including two dual-axis bogies, doubled by connecting casting or stamping-welded bolster, about 2.5 tons of weight, this is more than
The 20% of two bogie quality (9 tons).
It is known to have much patents on the body abutment device for dual-axis bogie (disclosed in July 4 nineteen ninety
SU1555164,MPK B61F5/02；RU 2051823, MPK B61F5/02, B61F5/14 disclosed in 1 day October in 1996) with
And other patents.These inventions are different because of body abutment design different on the truck bolster of bogie.These hairs
The bright main distinction between the classical scheme of 18-101 type bogie body abutments is the disk in the bridging bolster of bogie
Above and on the bearing part of the truck bolster of bogie it is provided with body abutment part.
As immediate prior art, employ in two dual-axis bogies (RU disclosed in 1 day October in 1996
2051823rd, MPK B61F5/02, B61F5/14) on body abutment device, it include it is described bridging bolster carrier center
Plate supporting member, is connected by the truck bolster of end plate supporting member and bogie, and the truck bolster of bogie is carried thereon
The bearing part of placement and with slit cylinder body, by the bearing part and with slit cylinder body, add bolster end can
To be positioned to be vertically moved, there is the additional bolster bearing part to be used to interact with main body in center section.It is described
Cylinder body is disposed on the load bearing member by ball bearing, and wherein installs the roller bearings of vertical spacing, the phase with additional bolster
To end contact.Moreover, some roller bearings are resisted against on corresponding cylinder body by spring loads.
In described invention, main body by its plate be placed in bridging bolster disk on and bogie additional bolster
On the bearing part of truck bolster., it is known that placement solid body is on seven supporting members (three disks and four bearing parts)
One uncertain system of static state.The bridging bolster receives vertical load.In immediate technology described in the prior
In scheme, the permissible load bridged on the spider of bolster depends on its rigidity.The demarcation rigidity for bridging bolster is by its quality
There is provided, it adds the total quality of vehicle, and this is very undesirable, because it causes the pressure on wheel pair and track
Increase, and generally reduce the bearing capacity of vehicle.
The content of the invention
Proposed invention is solved in the case where not reducing its bearing capacity and in the bent portion by track
When do not make bogie of car curve performance degenerate in the case of, by by from bridging bolster spider main body load again
It is assigned on the sidepiece bearing part of truck bolster and by " spider of main center's plate-bridging bolster " and " main body
The problem of construction change of the bearing assembly of the sidepiece bearing part of side support members-truck bolster " reduces main quality.
In order to reach preferable technical result, pacify in eight axle railroad vehicles, including by its sidepiece and central support pieces
The main body on two four-shaft steerings is put, the twin shaft that each four-shaft steering is connected by two by bridging bolster turns to
Frame is formed, and the bridging bolster is included in its upside and is used to support the spider of central plate and be used to be placed on the downside of it to turn
To two end plates on the disk of frame bolster, the truck bolster is provided with sidepiece bearing part, proposes in the bridging bolster
Cartridge is constructed in the form of sleeve, and the main center's plate being supported on is in a tubular form, and it passes through sliding connection to set
Cylinder.Also, it has been proposed that the side support members of main body are placed on the sidepiece bearing part of truck bolster, wherein side support members of main body
The form of roller or plate is configured to, and bearing part is correspondingly the form of plate or roller bearing.
The technical solution proposed eliminates spider transmission of the vertical load from main quality to bridging bolster.Four
2 tons of axle bogie Mass lost, without damaging its bearing capacity.Main body load is redistributed --- from bridging bolster
Cartridge is used to reduce to the sidepiece bearing assembly of " the sidepiece bearing part of side support members-truck bolster of main body " each
In the sidepiece bearing assembly of the frictional resistance of the bent portion of track, the side support members of main body are configured to the form of roller,
And bearing part is configured to the form of plate；Or supporting member constructs in the form of a plate, and bearing part is correspondingly configured to roller
The form of bearing.
Brief description of the drawings
In Figure of description, display is as follows：
Eight axle railroad vehicles of Fig. 1-proposition；
The top view of Fig. 2-four-shaft steering, it is made up of two dual-axis bogies, the dual-axis bogie is by bridging bolster
Connection；
The front view of the scheme of main center's plate on the spider of four axles of Fig. 3-be placed in bridging bolster, four-shaft steering
Vertical section on symmetry axis；
The side support members of Fig. 4-main body, it is configured to the form of roller.
Marked in appended scheme using the following drawings：
1- dual-axis bogies；2- bridges the plate of bolster；3- bridges bolster；The disk of 4- truck bolsters；5- truck bolsters；
6- main bodys；The side support members of 7- main bodys；The bearing part of 8- truck bolsters；9- main center plate-pipe；10- sleeves.
Embodiment
On dual-axis bogie 1, bridging bolster 3 is placed on the disk 4 of truck bolster 5 by central plate 2 and passes through pivot
Axis connection.
The side support members 7 on bearing part 8 that the lower frame of self-unloading vehicle main body 6 passes through truck bolster 5 dispose, and
It is fixed to by the main center's plate 9 of a diameter of 250-300 millimeters in a tubular form in the lower frame of main body 6, main center's plate leads to
Sliding connection is crossed to sleeve 10, the sleeve is fixed on the center of bridging bolster 3.
From stress load on eight axle bogies and immediate eight axle bogie described in the prior art proposed
Numerical procedure compares as can be seen that the center bridging bolster of immediate prior art bogie is only by vertical load, longitudinal direction
With draw and sidepiece bolster-side force.In the bogie proposed, vertical load Q/4 (Q- main qualities it is vertical
Load) it is applied to the bearing part 8 of truck bolster 5.Horizontal load (the traction from connector in the bogie proposed
Effect and impulsive force) sleeve 10 of bridging bolster 3 is applied to from central plate-pipe 9, and it is further applied to truck bolster 5
Disk 4.
In order to which the wheel on the bent portion of track is to the stability of motion and the performance of bogie, from by sidepiece
The moment of friction that supporting member 7 is placed on the bearing part 8 of truck bolster is necessarily equal to the torque of operating experience confirmation, the torque
For 12kNm.As shown by the research and calculating of the dumper run under a load, side support members 7 meet this
Roller form (Fig. 4) condition is configured to, the roller is bolted to the pivot brackets of the lower frame of self-unloading vehicle main body 6
On.
For lorry in small distance between main body frame and bogie bearing part, it is proposed that one kind design, it is included in
Side support members in main body, are configured to flat type；And the bearing part on bogie, it is configured to flat needle-like or roller
Bearing type." support plate-flat roller bearing " is somebody's turn to do to being selected according to strength condition, and meets required friction torque.
During the eight axle railroad vehicles proposed are mobile on linear rail track, because they are resisted against spring suspension
On, truck bolster is by the uniform load of power Q/4.When by curved in tracks part, by select " roller-plate " or
The normal performance that " plate-roller bearing " comes on offer curves to required friction torque.
