Abstract
A kind of high-speed EMUs axle box device for the conversion of quasi- broad gage, including axle box swivel arm beam and pivoted arm hoop, it is characterised in that：The cavity internal clearance cooperation that axle box swivel arm beam, pivoted arm hoop are constituted is equipped with axle box, axle box, axle box swivel arm beam, pivoted arm hoop section be corresponding polygonal cross-section, side is provided with the installation interface of retaining mechanism, mounting base of the pivoted arm hoop bottom as load carrier, axle box swivel arm beam, pivoted arm hoop are equipped with the installation interface of shaft end composition.Axle box and axle box swivel arm beam, pivoted arm hoop three body axle box of the mechanism by polygonal cross-section, realize that axle box slides axially in the inner cavity that axle box swivel arm beam and pivoted arm hoop are constituted, and it realizes circumferentially positioned, since three body axle box sides are provided with the installation interface of retaining mechanism, pivoted arm hoop bottom is equipped with the installation interface of load carrier, axle box swivel arm beam, pivoted arm hoop are equipped with the installation interface of shaft end composition, it smoothly realizes and becomes rail process, the increase for reducing human and material resources cost caused by replacing bogie when transnational through transport, improves efficiency of operation.
Description
Technical field
The utility model is related to a kind of rail car axle box device, converted in quasi- broad gauge more particularly, to a kind of apply
Axle box device on high-speed EMUs gauge changing power truck.
Background technology
In traditional steering framing wheel set axle box device, wheel is installed on by interference fit on axle, between the two relatively
It is fixed, therefore distance between backs of wheel flanges remains unchanged, and 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, Chinese railway is standard gauge, gauge 1435mm, and Russian and most of Eastern Europe, Central Asia are national
Railway is broad gauge, gauge 1520mm.Therefore, during carrying out transnational through transport, domestic passenger traffic, freight transportation railway vehicle by
When standard gauge lines are run to broad guage line, can not directly it pass through, need to more stop the bogie replaced and adapt to different gauge requirements
It could continue to run, there are the increase of human and material resources cost, the problems such as time-consuming, and efficiency of operation is low.
Utility model content
To solve the above-mentioned problems, the demand that gauge variation is adapted in the case of not parking replacement bogie is realized, this
It just needs to realize that relative displacement changes when gauge changes between wheel shaft, can be kept not after completing gauge variation
Become, it is therefore desirable to research and develop a kind of completely new axle box component devices, realize wheel horizontal sliding on axle, change wheel to inside
Away from.
To achieve the above object, the utility model provides a kind of high-speed EMUs axle box dress for the conversion of quasi- broad gage
It sets, including axle box swivel arm beam and pivoted arm hoop, it is characterised in that：The cavity internal clearance cooperation that axle box swivel arm beam, pivoted arm hoop are constituted
Equipped with axle box, axle box, axle box swivel arm beam, pivoted arm hoop section be corresponding polygonal cross-section, side is provided with locking machine
The installation interface of structure, mounting base of the pivoted arm hoop bottom as load carrier, axle box swivel arm beam, pivoted arm hoop are equipped with shaft end composition
Interface is installed.
The axle box, axle box swivel arm beam, pivoted arm hoop corresponding polygonal cross-section be octagonal cross-section.
The installation interface of the retaining mechanism is several corresponding locking keyways, passes through the locking with retaining mechanism
The safe locking become before and after rail is realized in bar cooperation.
An inverted U-shaped groove is opened in the mounting base bottom of the load carrier, and load carrier is inserted into installation in groove and fixes.
Axle box and axle box swivel arm beam, pivoted arm hoop three body axle box of the utility model by polygonal cross-section realize axis
Babinet slides axially in the inner cavity that axle box swivel arm beam and pivoted arm hoop are constituted, and realize it is circumferentially positioned, due to three body axle box sides
Face is provided with the installation interface of retaining mechanism, and pivoted arm hoop bottom is equipped with the installation interface of load carrier, on axle box swivel arm beam, pivoted arm hoop
Installation interface equipped with shaft end composition is smoothly realized and becomes rail process, and manpower, object caused by bogie are replaced when reducing transnational through transport
The increase of power cost, improves efficiency of operation.
Description of the drawings
Fig. 1 is the stereogram of axle box in the utility model；
Fig. 2 is the exploded view of axle box.
Specific implementation mode
Referring to Fig.1, Fig. 2, the utility model include axle box 1, pivoted arm hoop 2 and axle box swivel arm beam 3, and axle box is located at axis
Case pivoted arm beam, pivoted arm hoop constitute inner cavity in inner cavity clearance fit, axle box, axle box swivel arm beam, pivoted arm hoop section be phase
Corresponding octagonal cross-section prevents the effect of inertia rotated due to axle, leads to circumferentially rotating for axle box, octahedral structure
The cooperation of more planes, may be implemented circumferentially positioned, and can disperse the vertical force that axle box is born, that improves axle box composition uses the longevity
Life.Axle box 1, pivoted arm hoop 2 and 3 side of axle box swivel arm beam are provided with installation of the corresponding locking keyway 4 as retaining mechanism
Interface ensures the installation positioning of retaining mechanism, while the phase of axle box and axle box swivel arm beam is realized by the movement of retaining mechanism
To sliding.Mounting base of 2 bottom of pivoted arm hoop as load carrier is provided with the inverted U-shaped fixed load carrier of installation interface installation above,
Ensure that load carrier is contacted with ground rail changing device, is carried when being slided for axle box.Axle box swivel arm beam, pivoted arm hoop are equipped with axis
Hold the installation interface 5 of composition.
