Description
Technical field
The utility model belongs to rail vehicle technology, and in particular to a kind of radial type motor train unit bogie.
Background technology
Country's articulated mounting and bolster formula articulation steering frame are generally used on tramcar vehicle and motor passenger vehicle at present,
General axis is no more than 10t again.And EMUs vehicle axle weight is typically larger than on 17t, even up to more than 19t, therefore EMUs and cut with scissors
Connection technology application is more difficult.Adapt to that low station platform, curve negotiation ability be strong, vehicle cost because radial type EMUs vehicle has
It is relatively low, platform construction cost and purchase of vehicle cost can be greatlyd save, is had widely in European market and domestic market
Market application value.
Connection between radial type EMUs vehicle articulation steering frame and car body belongs to extremely crucial part, connection can
The safe operation and passenger's ride quality of vehicle are directly influenced by property and reasonability, while to the transport of vehicle, maintenance, answering
Rail operation has large effect.
Patent 201410639447.3 discloses a kind of articulated bogie, before and after longitudinal direction two groups (every group two)
Air spring carries respective one end of two section car bodies and carried realizing vehicle and adapts to the deflection of car body and traversing respectively；Using tool
Have integral lifting and prevent air spring from overcharging the anti-rolling device of function realize permutation car lift by crane during vehicle with
The integral lifting of bogie simultaneously prevents air spring from overcharging；Realize that the low level of car body is hinged using radial type draw-gear.
Although such scheme have devised EMUs articulation steering frame, but the problem of some details on also exist and lack
Fall into, be mainly manifested in:
1. the connection between its anti-rolling device and car body is using welding, because car body is with respect to bogie during operation
Motion, the reversed fatigue stress that anti-side rolling drawing depression bar is produced is easily caused weld cracking.
2. draw-gear on vehicle body bottom frame with when being hinged mounting seat and being connected, using plain nut and pad being split type
Install, its anti-loosening property is poor, there is certain potential safety hazard.
Utility model content
In view of the above-mentioned problems, the utility model aims to provide the radial type motor-car that a kind of structural strength is stable, security is good
Group bogie.
The utility model solve problem technical scheme be：A kind of radial type motor train unit bogie, including framework, symmetrical peace
Loaded on four air springs on framework, with the radial type draw-gear that mounting seat is connected of being hinged on vehicle body bottom frame, symmetrical peace
Loaded on four anti-rolling devices on framework, the torsion bar and car body side bar of anti-rolling device are removable by torsion bar mounting seat and framework
Unload connection；
The torsion bar mounting seat is several character form structures, and it includes the door shape portion for being used to be arranged in car body side bar die cavity, door
The mounting hole for being connected with car body side bar is provided with the top of shape portion, door shape subordinate end edge is transversely horizontal-extending to have connection convex
The mounting hole for being connected with torsion bar is provided with platform, connection boss.
In such scheme, torsion bar mounting seat is a few font overall structures, it is to avoid turned during operation because car body is relative
To the motion of frame, the problem of reversed fatigue stress that anti-side rolling drawing depression bar is produced causes weld cracking.
Further, articulated draw-gear is connected in diverse location respectively with being hinged mounting seat, each connection
By multiple bolt connections at position, the bolt at each link position constitutes a bolt connection region；
In bolt connection region provided with backing plate is installed, correspondence bolt position is provided with multiple confession bolts and worn on the installation backing plate
The mounting hole crossed；After bolt fastening, the entirety that all bolts of the join domain are integrated into a linkage by backing plate is installed.
In above-mentioned further improved scheme, the split type peace of traditional plain nut and pad is replaced using installation backing plate
Dress form, by the interlocking between different fastening points position, enhances the globality of mounting structure, prevents with more excellent
Loose performance, and when reducing installation and changing artificial, improve the maintainability of draw-gear.
Further, in addition to four anti-hunting damper holders being symmetrically arranged on framework, the anti-hunting damper holder
By resisting snakelike shock absorber mounting seat to be connected with car body side bar, this resists snakelike shock absorber mounting seat to include pedestal, at pedestal two ends
Respective slot interior installing hole position on mounting hole, thread plate is offered in the groove opened up, the thread plate being assemblied in groove, groove
Put and offer screwed hole；
The pedestal and car body side bar welding, anti-hunting damper holder are threadedly coupled with thread plate.
Remarkable result of the present utility model is：
1. the connection between anti-rolling device and car body uses integral structure component, it is to avoid due to car body phase during operation
Motion to bogie, the problem of reversed fatigue stress that anti-side rolling drawing depression bar is produced causes weld cracking.
2. draw-gear is connected using monoblock type connection with the mounting seat that is hinged on vehicle body bottom frame, pass through different fastening points position
Between interlocking, with more excellent anti-loosening property, and reduce installation and when changing artificial, improve draw-gear
Maintainability.
