Embodiment
Reference picture 1, Fig. 2, the specific embodiment of the invention include power axletree 1, wheel 2, gear-box 3, load bearing seat 4, cunning
Telephone-moving structure 5, axle box swivel arm beam 6, locking positioning pin 7, wheel are brake disk mounted 8, axial positioning mechanism 9, and wheel brake disk mounted 8 passes through fastening
Part connects wheel 2, and slipping mechanism 5 is arranged on power axletree 1, and axial restraint is carried out by locking positioning pin 7.Wheel 2 and axle
Case pivoted arm beam 6, which is set with, to be fixed on slipping mechanism 5, and band motor car wheel 2 is in power axletree 1 when slipping mechanism 5 is used to become rail
Sliding, coordinate with power axletree during operation and transmit moment of torsion, band motor car wheel rotates, and locking positioning pin 7 is located at slipping mechanism 5 and axle box
Between pivoted arm beam 6, i.e., by gauge changing when, locking positioning pin 7 to slipping mechanism unlock, slipping mechanism depart from locking positioning pin limit
System, arrow gauge is slid onto, after sliding comes, locking positioning pin 7 again fixes slipping mechanism 5 and axle box swivel arm beam 6, load bearing seat
4 are arranged on axle box swivel arm beam bottom, and when vehicle is by ground rail changing device, load bearing seat contacts with ground rail changing device, vehicle
Load is transferred to ground, the normal pressure of sliding interface by the pass order of axle box swivel arm beam-load bearing seat-ground rail changing device
The only deadweight of wheel and slipping mechanism, so as to reduce force of sliding friction, change rail process is set smoothly to realize.Due to slipping mechanism
It is that gap coordinates between 5 and power axletree 1, axle box swivel arm beam 6, relative can slides, power axletree loses axially position, because
This, axial direction positioning device 9 is installed at the both ends of power axletree 1, and connection power axletree 1 and axle box swivel arm beam 6 realize power axletree
Axially position.
Reference picture 3, need to slide relatively between slipping mechanism and power axletree, but because normal pressure is larger, between metalwork
Coefficient of friction it is also larger, cause frictional force very big, sliding is difficult, and therefore, the present invention develops a kind of to be passed by sliding bearing
The mode of force of sliding friction is passed, realizes that the low friction between slipping mechanism and power axletree is slided, so as to reduce sliding interface
Frictional force, while damaging in slipping and fretting wear are reduced, service life is improved, reduces maintenance difficulties and dimension
Protect cost.
Described slipping mechanism includes axle box 501, axle box bearing 502, dust slinger 503, journal box rear cover 504, sliding
Bushing 505, sliding bearing 506, locking nut 507, axle box 501 connect journal box rear cover 504, dust slinger by fastener
503 and axle box bearing 502 by be interference fitted connect slip bush 505, locking nut 507 be connected through a screw thread installed in sliding
On bushing, slip bush endoporus installation sliding bearing 506.Axle box 501, dust slinger 503, journal box rear cover 504 and locking
Nut 507 compresses axle box bearing 502 jointly.
When gauge changes, locking positioning pin unblock, slip bush can slide on power axletree, due to wheel, prevent
Dirt back-up ring and axle box bearing connect slip bush by being interference fitted, so, wheel slides on power axletree, is slided by standard gauge
To narrow gauge, when gauge change is completed, locking positioning pin locks slip bush again, limits its axial slidability, realizes wheel pair
Run away from the new gauge numerical value of adaptation is fixed on inner side.
In general axle box is all cylinder, under the effect of inertia that axletree rotates, because axle box is not fixed, and axle box
Body may circumferentially rotate.To prevent circumferentially rotating for axle box, present invention design axle box is octagonal cross-section, is realized
Axle box slides axially in axle box swivel arm beam inner chamber, while is coordinated by the plane of octagonal cross-section structure, and it is circumferential fixed to realize
Position.Multiple positioning holes are provided with above axle box and axle box swivel arm beam, by locking positioning pin, are realized to sliding front and rear lock
Tightly.
Reference picture 4, slipping mechanism of the invention coordinate with power axletree 1 for gap, relative can slide, lose transmission
The effect of moment of torsion.Therefore, by processing external splines, the cylindrical surface of slip bush 505 in the end periphery of power axletree 1
Internal spline is processed, when power axletree rotates, moment of torsion is transmitted by spline engagement, power axletree is realized with slip bush, wheel
Synchronous rotary, and spline relative can slide during rail is become.
Reference picture 5, described axial positioning mechanism include protecgulum 901, outer press cover 902, keeper 903, shaft end pressure plate
904th, adpting flange 905, protecgulum 901 are arranged on axle box swivel arm beam by fastener, and outer press cover 902 is arranged on by fastener
On protecgulum 901, shaft end pressure plate 904 is arranged on adpting flange 905 by fastener, and adpting flange 905 passes through fastener power
On axletree, the interference fit of keeper 903 is arranged on adpting flange 905.Keeper selection thrust bearing, 4 ball bearings, bullets
Property node or rubber spring, protecgulum, outer press cover, shaft end pressure plate and power axletree compress keeper 903 jointly.Keeper
One end connects axletree, and the other end connects axle box swivel arm beam by protecgulum 901, fixed so as to which power axletree and axle box swivel arm beam be passed through
Position part is directly connected to, and realizes axletree axially position.
Reference picture 6, load bearing seat is connected above with fastener with the bottom neck of axle box swivel arm beam 6, when vehicle passes through ground
During rail changing device, slipping mechanism slides, and load bearing seat contacts with ground rail changing device, carries car load, sliding interface is just
Pressure is only the deadweight of wheel and slipping mechanism, so as to reduce force of sliding friction, change rail process is smoothly realized.
Reference picture 7, the left side is the power wheel set axle box device configuration state run on standard gauge, when vehicle is become by ground
Before rail device, locking positioning pin is pulled down.Become rail to complete after moving to the right narrow gauge state, insert locking positioning pin, realize inner side
