Description
Technical field
The present invention relates to a kind of rail car axle box device, more particularly, to a kind of high speed applied in the conversion of quasi- broad gauge
Axle box device on EMUs gauge changing power truck.
Background technology
In traditional steering framing wheel set axle box device, wheel is installed on axletree by interference fit, between the two relatively
It is fixed, therefore distance between backs of wheel flanges keeps constant, is only capable of meeting a kind of service requirement of gauge.And countries in the world use different iron
Rail is away from standard, and Chinese railway is standard gauge, gauge 1435mm, Russian and most of Eastern Europe, Central Asia country
Railway is broad gauge, gauge 1520mm.Therefore, during transnational through transport is carried out, domestic passenger traffic, freight transportation railway vehicle by
, can not be directly by the way that need to more stop the bogie changed and adapt to different gauge requirements when standard gauge lines are run to broad guage line
It could continue to run, the increase of human and material resources cost be present, time-consuming, the problems such as efficiency of operation is low.
The content of the invention
In order to solve the above problems, the demand that gauge change is adapted in the case of not parking replacing bogie is realized, this
Just need to realize that relative displacement changes when gauge changes between wheel shaft, can be kept not after completing gauge change
Become, it is therefore desirable to research and develop a kind of brand-new axle box component devices, realize wheel horizontal sliding on axletree, change wheel to inner side
Away from.
To achieve the above object, the present invention provides a kind of EMU axle box device for the conversion of quasi- broad gage, bag
Include axle box swivel arm beam and pivoted arm hoop, it is characterised in that：The cavity internal clearance that axle box swivel arm beam, pivoted arm hoop are formed, which coordinates, is provided with axle
Casing, axle box, axle box swivel arm beam, the section of pivoted arm hoop are corresponding polygonal cross-section, and side is provided with the peace of retaining mechanism
Attaching mouth, mounting seat of the pivoted arm hoop bottom as load carrier, the installation that axle box swivel arm beam, pivoted arm hoop are provided with shaft end composition connect
Mouthful.
Described axle box, axle box swivel arm beam, the corresponding polygonal cross-section of pivoted arm hoop are octagonal cross-section.
The mounting interface of described retaining mechanism is several corresponding locking keyways, passes through the locking with retaining mechanism
Bar coordinates the safe locking realized and become before and after rail.
An inverted U-shaped groove is opened in the mounting seat bottom of described load carrier, installs and fixes in load carrier insertion groove.
Axle box and axle box swivel arm beam, pivoted arm hoop three body axle box of the present invention by polygonal cross-section, realize axle box
Slid axially in the inner chamber that axle box swivel arm beam and pivoted arm hoop are formed, and realize it is circumferentially positioned, because three body axle box sides are opened
There is the mounting interface of retaining mechanism, pivoted arm hoop bottom is provided with the mounting interface of load carrier, and axle box swivel arm beam, pivoted arm hoop are provided with
The mounting interface of shaft end composition, smoothly realize and become rail process, human and material resources caused by changing bogie when reducing transnational through transport into
This increase, improves efficiency of operation.
Brief description of the drawings
Fig. 1 is the stereogram of axle box in the present invention；
Fig. 2 is the exploded view of axle box.
Embodiment
Reference picture 1, Fig. 2, the present invention include axle box 1, pivoted arm hoop 2 and axle box swivel arm beam 3, and axle box is located at axle box and turned
Coordinate in the inner chamber that arm beam, pivoted arm hoop are formed with interior cavity gap, axle box, axle box swivel arm beam, the section of pivoted arm hoop are corresponding
Octagonal cross-section, prevent the effect of inertia rotated due to axletree, cause circumferentially rotating for axle box, octahedral structure it is more flat
Face coordinates, it is possible to achieve and it is circumferentially positioned, and the vertical force that axle box is born can be disperseed, improve the service life of axle box composition.
Axle box 1, pivoted arm hoop 2 and the side of axle box swivel arm beam 3 are provided with corresponding locking keyway 4 and connect as the installation of retaining mechanism
Mouthful, ensure the installation positioning of retaining mechanism, while realize that axle box is relative with axle box swivel arm beam by the motion of retaining mechanism
Slide.Mounting seat of the bottom of pivoted arm hoop 2 as load carrier, the inverted U-shaped fixed load carrier of mounting interface installation is provided with above, is protected
Card load carrier contacts with ground rail changing device, is carried when being slided for axle box.Axle box swivel arm beam, pivoted arm hoop are provided with shaft end
The mounting interface 5 of composition.
