Specific implementation mode
Referring to Fig.1, Fig. 2, specific embodiment of the present invention include power axle 1, wheel 2, gear-box 3, bearing seat
4, slipping mechanism 5, axle box swivel arm beam 6, locking positioning pin 7, wheel be brake disk mounted 8, axial positioning mechanism 9, and wheel brake disk mounted 8 passes through
Fastener connects wheel 2, and slipping mechanism 5 is mounted on power axle 1, and axial restraint is carried out by locking positioning pin 7.Wheel 2
It is set with and is fixed on slipping mechanism 5 with axle box swivel arm beam 6, band motor car wheel 2 is in power axle when slipping mechanism 5 is for becoming rail
It is slid on 1, transmits torque when operation with the cooperation of power axle, band motor car wheel rotates, and locking positioning pin 7 is located at 5 He of slipping mechanism
Between axle box swivel arm beam 6, i.e., by gauge changing when, locking positioning pin 7 to slipping mechanism unlock, slipping mechanism be detached from locking positioning pin
Limitation, be slid onto arrow gauge, after sliding comes, locking positioning pin 7 again fixes slipping mechanism 5 and axle box swivel arm beam 6, holds
It carries seat 4 and is mounted on axle box swivel arm beam bottom portion, when vehicle is by ground rail changing device, bearing seat is contacted with ground rail changing device,
Car load is transferred to ground, sliding interface is just by the pass order of axle box swivel arm beam-bearing seat-ground rail changing device
Pressure is only the dead weight of wheel and slipping mechanism, to reduce force of sliding friction, change rail process is made smoothly to realize.Due to sliding
It is clearance fit between mechanism 5 and power axle 1, axle box swivel arm beam 6, opposite can slides, power axle loses axial fixed
