Background technology
With the proposition of the Belt and Road strategic idea, come and gone between China and periphery various countries by the commerce and trade of railway transportation
Increasingly frequently, and a plurality of railway international combined transport and region through transport passage have been carried out between China and neighbouring country." Silk Road economy
Band " makes Euro-Asia Continental Bridge become its important railway traffic as one of most important trade by roadway passage in the unicom Eurasia
Tie is transported, is to bring happiness along road area people's economy.However, due to history, the iron in country variant and area
Road employs different gauge specifications.
Modernization bogie increasingly tends to be intelligent, and motor and gear-box are provided with the axle of inside wheel, and
Other electrified equipment.Since inside wheel space is limited, traditional reel mode of braking is replaced with wheel by modernization bogie
Disk mode of braking.In railway of the train Jing Guo different gauge specifications, conevying efficiency is preferably improved using gauge-changeable bogie.Become
The wheel of gauge bogie adjusts in axle axial direction, so as to fulfill conversion bogie wheel to wheelspan to adapt to different rails
Away from.But existing disc brake is integrally fixed on bogie, can not be moved with the Multiple disc brake disk on wheel
It is dynamic.And brake apparatus is the necessaries of bogie, therefore, gauge-changeable bogie selects to sacrifice the intelligence of bogie under compulsion
Change, give inside wheel space to be preserved to reel brake disc.This just brings limitation to the development of gauge-changeable bogie.
Utility model content
The purpose of this utility model is that:The problem of can not using Multiple disc brake mode for gauge-changeable bogie, there is provided
A kind of brake clamp locating piece applied to gauge-changeable bogie, is applied to disc brake by the brake clamp locating piece,

State brake clamp mounting base E2 and further include brake clamp mounting portion E21, the brake clamp mounting portion E21 is slidably connected with described
Portion E22 is interconnected.
The brake apparatus is the disc brake that can be automatically positioned with the conversion of gauge.High-speed EMU in the world
More foundation brake modes braked using Multiple disc brake and reel, due to that need to consider motor, gear-box when power axle designs
Space layout problem, under the limited space of bogie, the less use of reel mode of braking.CRH2 type car power axles all use
Frame suspension type motor drives the torsion pass mode of reduction gear box, and occupied space is larger, can only use Multiple disc brake mode.Therefore, originally
Embodiment uses Multiple disc brake mode, and design accordingly can follow wheel to move together, again can be certainly after gauge changing is completed
Brake apparatus of the moving axis to locking positioning.Brake apparatus other equipment uses prototype structure, such as brake clamp, brake cylinder, ring
Shape Moving plate, cooling fin;Brake clamp is made of brake pad, brake lever etc..Brake pad by brake lining buting iron, brake plate support,
Powder metallurgy brake pad etc. forms.
The fixed part E11 of flap seat E1 is braked, i.e. L-type connector is installed on the crossbeam of bogie frame.Brake flap seat E1
Sliding engagement portion E12 it is also corresponding axial widen, make the slide contact part E22 of brake clamp mounting base E2 axially have sufficient sky
Between for movement, meet in the case of different gauges with the axial movement distance of wheel.If in 1435mm standard gauges position and 1520mm wide
Rail converts between position, then end-play need to ensure 42.5mm.Pass through dovetail between braking flap seat E1 and brake clamp mounting base E2
The fit system installation of groove, i.e. brake clamp mounting base E2 is dovetail body inverted trapezoidal guide rail, and braking flap seat E1 is dovetail groove.Dovetail
Slot structure standard uses JB/ZQ4241-1997 professional standards.The mechanical connection manner that dovetail groove coordinates with dovetail body, has fortune
Dynamic precision is high, the advantages of stabilization, is chiefly used in heavy duty, the not high occasion of speed.Both it can ensure that brake apparatus was reliably hung in structure
Frame crossbeam it is upper, can also ensure that it can follow axletree to slip during gauge changing.
To prevent the axial displacement caused by micro breadth oscillation, it is designed with brake clamp in dovetail groove centre position and determines
Position block E3, by a compression spring, i.e. return unit E32 is nested in a lock piece E31 and forms, by the way that lock piece E31 is pacified
In embedded groove E13.Accordingly brake clamp mounting base E2 trapezoidal rails Position Design have interval 42.5mm rectangle
Location groove E23 (or axial spacing is determined according to the requirement of converted gauge), for locking for axial lock piece E31.
In dovetail groove both sides, for dovetail body guide rail slide axially it is excessive be designed with limiting plate E14, be installed on by screw
In the plane of dovetail groove two sides.Limiting plate E14 and dovetail groove split-type design, it is ensured that the machinery of swallow-tail form notch adds
The correct installation of work and trapezoidal rails.When needing to separate trapezoidal rails, dovetail groove limiting plate E14 only need to be pulled down first.
Meanwhile fabrication design size is adjusted, it is sliding when slide contact part E22 slides into one end, and lock piece E31 is located in location groove E23
One end of rotation connection E22 is contacted with limiting plate E14 just, is reached accurate stable position restriction effect, is made brake clamp
Location determination is more accurate.
When wheel initially axially gauge changing, axial force forces the lock piece E31 at dovetail groove to be transported into embedded groove E13
Dynamic, spring is pressurized to contract, while lock piece E31 is pressed into embedded groove E13, the confinement block E24 of trapezoidal rails no longer by
The backstop of lock piece E31, can move axially.When gauge position as defined in arrival, resetting spring promotes lock piece E31 automatically
Stretch out, locked with location groove E23, so as to limit the axial movement of brake apparatus.
By taking wheel gauge is changed into the conversion process of 1520mm broad gauges position from 1435mm standard gauges position as an example, illustrate the brake apparatus
Conversion process, and its operation principle:
(1) when wheel gauge is changed into broad gauge position (1520mm) from standard gauge position (1435mm), the wheel disc on wheel
Brake disc moves.
(2) the mobile drive brake clamp movement of Multiple disc brake disk, under the action of axial force, brake clamp drives braking
Trapezoidal rails on clamp mounting base E2 force the lock piece E31 at dovetail groove to compress and are pressurized to contract, spring, locking
Part E31 is shunk.So far, disc brake is unlocked.
(3) after gauge needed for reach, the axial lock piece E31 at swallow-tail form notch under the action of resetting spring,
Lock piece E31 is stretched into trapezoidal rails and is spaced in another rectangle position groove of 42.5mm, and disc brake is also accordingly locked
Tightly.It is finally reached broad gauge position.
When Wheel centre distance narrows from the width, whole conversion process need to only move in the opposite direction with above-mentioned essentially identical according to wheel
It is dynamic.Meanwhile can the disc brake of auto lock also move in the opposite direction.
