Description
Technical field
The invention belongs to railway machinery design and manufacturing technology field, and in particular to a kind of two axles with lock function turn
To frame.
Background technology
With the development of China's railway construction, various engineering trucks and railway breakdown vehicle turn into must match somebody with somebody equipment.In engineering
In vehicle or breakdown lorry operation, stability requirement during due to equipment availability on vehicle frame is, it is necessary to steering framing wheel pair and framework, structure
There is no relative motion between frame and vehicle frame, in case vehicle frame swings, prevent slide-out, and need vehicle in low speed operation
Stabilization can be kept.Existing technology is usually that, using rigid side bearing, cartridge carries traction entirely；In vehicle operation, due to longitudinal direction
The horizontal swing of tractive force and vehicle, can produce rigid shock between upper center bearing；Again, due to manufacture and alignment error,
So that discontinuity between upper center bearing, when particularly car body is sidewindered in operation, body center plate is by edge transfer load, Yi Zao
Into the fatigue damage of cartridge.Rigid side bearing can not produce the revolution moment of friction of stabilization, it is impossible to which the effective vehicle that suppresses is in fortune
Crawling in row, it is impossible to meet the speed-raising requirement of railway equipment rescue aid.And on existing hot-short, using often contact side bearing
Plus the type of attachment of ball center plate, installing locking cylinder additional between vehicle frame and bogie, this kind of structure can cause upper and lower ball disk to separate,
Vehicle is unable to low speed traveling.In sum, it is necessary to be improved.
The content of the invention
Present invention solves the technical problem that：A kind of two axle truck with lock function is provided, by the side of framework
Being set on beam makes framework and wheel be that locking cylinder and two is locking to forming the one of rigid support between axle box, between framework and vehicle frame
Cylinder, vehicle frame swings when effectively prevent work, prevents slide-out, is rubbed using center ball pin and constant contact resilient other
That holds uses cooperatively so that loading end is more uniform between vehicle frame and bogie, and the flywheel moment of stabilization limits bogie
Shake the head hunting, improve the stability of vehicle, while limiting the rolling pendulum motion of car body, be conducive to the antidumping safety of vehicle
Property.
The technical solution adopted by the present invention：Two axle truck with lock function, with framework, installs on the framework
There is axletree and axletree two ends are provided with wheel to axle box, drive device, the horizontal stroke of the framework are installed on the axletree of described framework one end
Beam middle part is provided with center ball pin draw-gear and center ball pin draw-gear is fixedly connected with the vehicle frame above framework, described
Framework is provided with constant contact resilient friction side bearing and constant contact resilient friction side bearing branch positioned at center ball pin draw-gear both sides
Vehicle frame is supported in the top of framework after coordinating in bottom of frame and with center ball pin draw-gear for support, on the curb girder of the framework
Be provided with make between framework and vehicle frame, framework and wheel be to forming the locking device of rigid support between axle box.
Wherein, the locking device is that locking cylinder and two is locking cylinder including one, and the wheel is to the axle box top in axle box
It is provided with one to be locking cylinder and one be that locking cylinder is fixed on curb girder end, described one is that the piston for locking cylinder is supported on axle box downwards
The rigid support of framework and axle box is formed, described two is that locking cylinder is fixed in the middle part of curb girder and two is that the piston for locking cylinder is propped up upwards
Support the rigid support that framework and vehicle frame are formed on vehicle frame.
Further, the center ball pin draw-gear include center ball pin, upper ball disk, lower ball disk, traction seat, baffle ring and
Guide, the traction seat is in the middle part of crossbeam and lower ball disk and the baffle ring above lower ball disk are inside traction seat, institute
State lower ball disk be installed on traction seat inner bottom surface and baffle ring be fixed on traction seat middle part after form inner chamber between lower ball disk, it is described
Guide is provided with baffle ring and guide and baffle ring interference fit, the center ball pin upper end is fixedly connected and under the ball pin of center with vehicle frame
Hold through guide and be fixedly connected with the upper ball disk being located in inner chamber, after shifting makes ball disk and lower ball disk detachment in the center ball pin
Centrepin traction is formed, the center ball pin is moved down makes ball disk form the sphere heart after being contacted with the friction pad on lower ball disk
Disk draws.
Further, it is described to take turns to the axle box of axle box built with self sealss taper roll bearing and self sealss taper roller axle
Hold the end for being installed on axletree.
Present invention advantage compared with prior art：
1st, framework and wheel are made to forming rigidity branch between axle box, between framework and vehicle frame by the setting on the curb girder of framework
The one of support is that locking cylinder and two is locking cylinder, and vehicle frame swings when effectively prevent equipment availability, prevents slide-out；
2nd, the center ball pin in the middle part of crossbeam causes to be intimate contact, vehicle frame and bogie between vehicle frame and bogie
Between loading end it is more uniform, when vehicle high-speed runs, the motion around limiting between bogie and vehicle frame, often
What contact resilient friction side bearing inhibited vehicle sidewinders motion, while produce the flywheel moment of stabilization effectively to suppress vehicle transporting
Crawling in row so that vehicle has the speed of service higher；
3rd, the guide in traction seat is intrados structure, it is adaptable to when vehicle high-speed runs between vehicle frame and framework
Opposing oscillatory；
4th, when vehicle runs, two be after locking cylinder working by vehicle frame jack-up, it is upper in the center ball pin on vehicle frame
Ball disk is separated with the lower ball disk in traction seat on truck transom, and pin leads centered on the connected mode between vehicle frame and framework
Draw, meet the walking of vehicle low speed and require；
