Description
Technical field
The invention belongs to bogie of car technical field, and in particular to a kind of retaining mechanism for gauge-changeable bogie.
Background technology
Because international freight forwarding is more and more frequent, it is cross-border transport the gauge that runs into it is different the problem of can not leading directly to, become
Gauge roller bearing adapter stabilizer bar seems and is necessary that the retaining mechanism of existing gauge changing roller bearing adapter stabilizer bar is although varied, but
There are many weak points, as described in patent CN201310137008；Some retaining mechanisms are made using ball is spacing
It is small into lifting surface area, it is unfavorable for resisting big load wheel-rail lateral force；Some retaining mechanisms open up annular groove only on axletree or wheel hub
For one locating part of arrangement, axle hub intensity is not only reduced and lateral stressed uneven.
The content of the invention
It is an object of the invention to provide a kind of roller bearing adapter stabilizer bar variable pitch device, it can efficiently solve the stress of retaining mechanism
Uneven the problem of, 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
Axletree and wheel, wheel are fixed by the two ends of wheel hub and axletree, and wheel hub is spacing provided with the arrow gauge with limited post and broad gage
Structure, the external diameter surface of wheel hub is radially provided with arrow gauge blind hole and broad gage blind hole, and sleeve is fixed on the axletree of the inner side of wheel
On, the internal diameter of sleeve and the crest clearance of wheel hub coordinate；The external diameter of sleeve alleviates cylinder end provided with alleviation disk provided with cylinder is alleviated,
Alleviate disk and be along the circumferential direction uniformly provided with oblique fishing rod, the front end of sleeve is circumferentially provided with radial direction through hole, and middle part is provided with spring branch
Frame, is provided with release spring between sleeve and alleviation cylinder, limited post is provided 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 with the quantity of the radial direction through hole on sleeve, is opened up on cylinder oblique
The angle of the center line of through hole, insertion centerline hole and limited post is at an acute angle.
The quantity of blind hole of the quantity of the fishing rod with often enclosing is identical.
The angle of axis of the center line of the fishing rod with alleviating disk is equal to the center line of the oblique through hole on limited post
With the angle of the center line of limited post.
The acute angle is 45~75 degree.
The alleviation cylinder is fixed together by bolt with alleviating disk, alleviation cylinder can only be moved on sleeve along axis and by
To the recuperability of release spring.
Two row's blind holes on the wheel hub are corresponded in two kinds of gauges, the blind hole and sleeve that only current gauge is used respectively
Jack is corresponded, and is inserted limited post and fixed sleeve with wheel hub.
The beneficial effects of the invention are as follows：Fishing rod formula gauge changing retaining mechanism is arranged on the inner side of wheel, and mechanism is relatively independent,
Rear reheating can be assembled to be enclosed on axletree, it is not necessary to which the axle box of existing bogie is redesigned and transformed, without change axle
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.
Brief description of the drawings
Fig. 1 is general structure schematic cross-sectional view of the present invention；
Fig. 2 alleviates dish structure schematic diagram for the present invention；
Fig. 3 is the profile of limited post of the present invention.
Embodiment
The embodiment to 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, installed in the inner side of wheel 2, including it is spacing
Wheel 2 is installed, sleeve 8 is fixed on axletree 1 in hot jacket mode, and alleviation cylinder is provided with sleeve 8 on post 4, axletree 1, axletree 1
9th, 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
Unblock.Fishing rod formula variable rail gauge retaining mechanism is relatively independent, can assemble rear reheating and be enclosed on axletree, it is not necessary to turned to existing
The axle box of frame is redesigned and transformed, and without the design parameter for changing axle box hanging device, limited post 4 is circumferentially evenly arranged
Higher wheel-rail lateral force can be born, while the requirement on machining accuracy of the mechanism is not high, processing and manufacturing easily, reliability also compared with
It is good.
By the inner side of wheel 2 away from the embodiment that the present invention is discussed exemplified by the narrow gauge changing process broadened, turn to
When frame is run on narrow gauge, in the radial direction through hole 12 and arrow gauge blind hole 5 in the insertion sleeve 8 of limited post 4 and curve negotiating is born
When wheel-rail lateral force, when wheel 2 reach ground become rail facility after, alleviate cylinder 9 ground unblock rail in the presence of overcome alleviation
The resistance of spring 7, drives the fishing rod 10 alleviated on disk 11 to be moved together to the opposite direction of track centerline, the oblique edge of through hole 13
The axis of fishing rod 10 relatively moves and lifts limited post 4 until radial direction through hole 12 is completely disengaged from and rested on arrow gauge blind hole 5
In, now alleviate cylinder 9 and stop no longer moving in this position, wheel 2 starts under the booster action of gauge changing ground installation along car
The transverse shifting of axle 1, broad gage blind hole 6 is alignd with radial direction through hole 12 after the track of broad gage is reached, and at this moment allows alleviation cylinder 9 slow
Reset in the presence of spring 7 is solved, limited post 4, which is fallen into, makes wheel locking in broad gage blind hole 6, gauge changing process terminates.
The inner side of wheel 1 is the inverse process of said process, the locking of fishing rod formula gauge changing away from the gauge changing process narrowed from the width
Mechanism is purely mechanical structure, and whole transfer process can be automatically performed, and device is repaired with being very convenient to.
