Description
Technical field
The invention belongs to bogie of car technical fields, and in particular to a kind of retaining mechanism for gauge-changeable bogie.
Background technology
It is cross-border to transport the different problem that led directly to of the gauge encountered since international freight forwarding is more and more frequent, become
Gauge roller bearing adapter stabilizer bar seem it is necessary to, the retaining mechanism of existing gauge changing roller bearing adapter stabilizer bar is although varied, but
There are many shortcomings, as described in patent CN201310137008；Some retaining mechanisms are made using ball limit
It is small at forced area, it is unfavorable for resisting big load wheel-rail lateral force；Some retaining mechanisms open up annular groove only on axle or wheel hub
To arrange a locating part, axle hub intensity and lateral stressed uneven is not only reduced.
Invention content
The object of the present invention is to provide a kind of roller bearing adapter stabilizer bar variable pitch devices, it can efficiently solve the stress of retaining mechanism
Uneven problem, and larger wheel-rail lateral force can be born.
The mesh of the present invention is achieved through the following technical solutions：A kind of fishing rod formula variable rail gauge retaining mechanism, including
Axle and wheel, wheel are fixed by the both ends of wheel hub and axle, and wheel hub is equipped with the arrow gauge with limited post and broad gage limits
The external diameter surface of structure, wheel hub is radially provided with arrow gauge blind hole and broad gage blind hole, and sleeve is fixed on the axle of the inside of wheel
On, the internal diameter of sleeve and the crest clearance of wheel hub coordinate；The outer diameter of sleeve, which is equipped with, alleviates cylinder, and the end of the alleviation cylinder, which is equipped with, to be alleviated
Disk alleviates disk and is along the circumferential direction uniformly provided with oblique fishing rod, and the front end of sleeve is circumferentially equipped with radial through-hole, and middle part is equipped with spring
Holder, is equipped with release spring between sleeve and alleviation cylinder, limited post is equipped with oblique through hole.
The arrow gauge blind hole and broad gage blind hole of the external diameter surface of the wheel hub are evenly distributed in the circumferential direction, and arrow gauge is blind
Hole and four evenly distributed in the circumferential direction of broad gage blind hole.
The limited post is cylinder, and quantity is identical as the quantity of the radial through-hole on sleeve, is opened up on cylinder oblique
Through hole, the angle for penetrating through the center line of centerline hole and limited post are at an acute angle.
The quantity of the fishing rod is identical as the quantity for the blind hole often enclosed.
The center line of the fishing rod is equal to the center line of the oblique through hole on limited post with the angle for the axis for alleviating disk
With the angle of the center line of limited post.
The acute angle is 45~75 degree.
The alleviation cylinder is by bolt and alleviates disk and is fixed together, alleviate cylinder can only it is mobile in sleeve upper edge axis and by
To the recuperability of release spring.
Two rows of blind holes on the wheel hub correspond to two kinds of gauges respectively, in the blind hole and sleeve that only current gauge uses
Jack corresponds, and is inserted into limited post and fixes sleeve and wheel hub.
The beneficial effects of the invention are as follows：Fishing rod formula gauge changing retaining mechanism is mounted on the inside of wheel, and mechanism is relatively independent,
Rear reheating can be assembled to be sleeved on axle, the axle box of existing bogie need not be redesigned and is transformed, without change axis
The design parameter of case suspension arrangement, limited post, which is circumferentially evenly arranged, can bear higher wheel-rail lateral force, while the mechanism
Requirement on machining accuracy is not high, and processing and manufacturing is easy, reliability is also preferable.
Description of the drawings
Fig. 1 is overall structure schematic cross-sectional view of the present invention；
Fig. 2 is that the present invention alleviates dish structure schematic diagram；
Fig. 3 is the sectional view of limited post of the present invention.
Specific implementation mode
The specific implementation mode of the present invention is further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 3, a kind of fishing rod formula variable rail gauge retaining mechanism is mounted on the inside of wheel 2, including limit
Column 4, axle 1 are equipped with wheel 2 on axle 1, and sleeve 8 is fixed in a manner of hot jacket on axle 1, and alleviation cylinder is equipped on sleeve 8
9, alleviate disk 11, release spring 7 is arranged between sleeve 8 and alleviation cylinder 9, alleviate cylinder 9 and triggered using ground gauge changing device
Unlock.Fishing rod formula variable rail gauge retaining mechanism is relatively independent, can assemble rear reheating and be sleeved on axle, need not be to existing steering
The axle box of frame redesigns and transformation, and without the design parameter for changing axle box hanging device, limited post 4 is circumferentially evenly arranged
Can bear higher wheel-rail lateral force, while the requirement on machining accuracy of the mechanism is not high, processing and manufacturing be easy, reliability also compared with
It is good.
The specific implementation mode that the present invention is discussed so that 2 inside of wheel is away from by the narrow gauge changing process to broaden as an example, turns to
Frame in the radial through-hole 12 and arrow gauge blind hole 5 in 4 insertion sleeve 8 of limited post and bears curve negotiating when being run on narrow gauge
When wheel-rail lateral force, when wheel 2 reach ground become rail facility after, alleviate cylinder 9 ground unlock rail under the action of overcome alleviation
The resistance of spring 7 drives the fishing rod 10 alleviated on disk 11 to be moved together to the negative direction of track centerline, 13 edge of oblique through hole
The axis of fishing rod 10 relatively moves and lifts limited post 4 until being completely disengaged with arrow gauge blind hole 5 and resting on radial through-hole 12
In, alleviate the stopping of cylinder 9 at this time and no longer moved in this position, wheel 2 starts under the booster action of gauge changing ground installation along vehicle
1 transverse shifting of axis, broad gage blind hole 6 is aligned with radial through-hole 12 after the track for reaching broad gage, is at this moment allowed and is alleviated cylinder 9 slow
It is resetted under the action of solution spring 7, limited post 4, which is fallen into broad gage blind hole 6, makes wheel be latched, and gauge changing process terminates.
The inside of wheel 1 is the inverse process of the above process, the locking of fishing rod formula gauge changing away from the gauge changing process to narrow from the width
Mechanism is purely mechanical structure, and entire transfer process can be automatically performed, and device is repaired and is very convenient to.
