Description
Technical field
The invention belongs to field of track traffic, and in particular to a kind of tooth rail car bogie.
Background technique
Cogwheel railway is the rail for adding a band " tooth " again among common railway.The bogie being provided on tooth rail car
Rack rails wheel and the rack gear on route engage, to realize the traction and braking of rolling stock, maximum climbing slope can be with
Reach 250 ‰.
Tooth rail car is also relatively easily, to be unable to reach the condition of carrying operation in the application of the field of mining such as some coal mines.
Currently, rack drives device is generally wheel track and rack rails combination drive pattern, major defect is shown: it is driven using two axis,
Two groups of wheels are to corresponding driving device is above respectively equipped with, and the equipment installed on bogie is various, and structure is complicated, and driving device
Structure is complicated, needs to be equipped with special clutch switching device, and the bodily form and weight are very big, cause bogie overweight, to route
Load it is also very big, every cost of vehicle and route is all very high.
Summary of the invention
In view of the above-mentioned problems, simplified bogie structure improves the present invention is intended to provide a kind of can be effectively reduced light weight
The performance of bogie and the tooth rail car bogie of curve passing through passability.
The technical solution that the present invention solves the problems, such as is: a kind of tooth rail car bogie, including framework, installation architecturally two
Group wheel pair, two groups one group of wheel centering is driving wheel pair, and another group is non-driving wheel pair；
For the driving wheel to including drive shaft, the wheel for passing through bearing and driving axis connection, wheel relative drive shaft is independent
Movement；
Interference fit is equipped with rack rails wheel in the drive shaft, is connected on the framework for driving drive shaft to turn round
Driving device, the rack rails wheel include gear ring, the gear hub installed with drive shaft interference fit, gear hub wing plate, are located at gear
The end cap of hub lateral surface and gear hub wing plate lateral surface；
It is circumferentially spaced on gear hub end face to be provided with first through hole, it is circumferentially spaced on gear ring end face to be provided with and first
One-to-one second through-hole of through-hole, it is circumferentially spaced on gear hub wing plate end face to be provided with and first through hole one-to-one
Three through-holes, the end face of the gear hub, the end face of gear ring and gear hub wing plate end face three docking, gear ring be located at gear hub with
Between gear hub wing plate, and the first, second, third through-hole is aligned；Gear hub, gear ring, gear hub wing plate, end cap pass through fastener
It being fixedly connected sequentially, first through hole, the second through-hole, third through-hole and end cap inner sidewall surround to form individual cavities after connection,
Elastic element is equipped in the cavity, which abuts with a longitudinal end of the first, second, third through-hole simultaneously,
The other end of elastic element is abutted with another longitudinal end of the first, second, third through-hole simultaneously.
Above scheme replaces traditional Two axle drive using single shaft-driven structure, all wheels be all only to provide support and
Guiding role fully relies on rack rails wheel and provides traction.It is advantageous in that: can be saved on an other axle using list is shaft-driven
The installation of associated drives equipment simplifies bogie structure, reduces axis weight, mitigates bogie weight, can also shorten wheelbase, improves
The performance of bogie and the curve negotiating of vehicle.
Non-driving wheel in above scheme is to for wheel pair commonly used in the prior art.
Specifically, the driving device includes seizing bracket, being mounted on the traction electric machine seized on bracket and seize bracket
It is fixedly connected with and seizes with drive shaft the gear-box of installation, the pinion shaft and traction electric machine output shaft of gear-box pass through shaft coupling
Connection.
Traction electric machine directly drives rack rails wheel to rotate by gear-box, and wheel is driven, it is desirable that is laid with tooth on all routes
Rail bar, vehicle could be run.
Further, it is equipped with brake drum on the pinion shaft of gear-box and in drive shaft, brake drum and seizes support
Frame is fixed.
Mode of braking is arranged using two staged braking, is respectively provided with brake drum and independent control on high speed shaft and slow-speed shaft.Braking
Drum with seize bracket and fix, brake drum work is not influenced by sink-float above and below vehicle.
In above scheme, the effect of end cap is sealing, and the effect of gear hub wing plate is transmitting torsion.
Rack rails wheel fission is designed, elastic element is similar to tangential springs, and the purpose designed in this way is compensation rack rails wheel
With the pitch error in rack bar installation and operational process, it is ensured that the even running of vehicle improves and takes turns in rack rails wheel and rack bar
The stress of tooth reduces the severe impact of vehicle and route.
Preferably, the elastic element is spring or elastomer.
Further, the elastic element includes the limited block and spring of a pair of of mirror symmetry setting, institute's limited block packet
Include block and the vertically disposed bar of block；
The spring is set between two blocks, and is socketed on bar；
Gap is reserved between two bars, and the axis of two bars is on the same line；
The outer profile of the block longitudinal end and the longitudinal end shape of the first, second, third through-hole are identical.
When spring-compressed to a certain extent when, two bars are collided, and limited spring is compressed, and prevent spring by too strong
Impact force is crushed to death and causes to damage.
Preferably, the rack rails wheel is set to shaft center.
Further, the framework includes two parallel stringers, is set to stringer both ends and connects two stringers
During the distance between the axle of end carriage, the intermediate transverse girder for being set to stringer central region, intermediate transverse girder and non-driving wheel pair is less than
Between the distance between crossbeam and drive shaft.
Due to using single shaft-driven structure, driving wheel is greater than non-driving wheel pair to the weight of that side, for axis weight
Mean allocation, above-mentioned framework use asymmetrical structure type.
Remarkable result of the invention is:
1. light weight can be effectively reduced in uniaxial rack drives, simplify bogie structure, to alleviate vehicle and route
Specific load, the manufacture of vehicle and route, with and maintenance cost be greatly reduced.Also it can shorten wheelbase, improve bogie
The curve negotiating of performance and vehicle.
2. the wheel independent design of driving wheel pair, wheel can be movable relatively with axle, the movement of rack rails wheel and wheel is realized
Lotus root is solved, to guarantee full line rack rails wheel drive.
3. rack rails wheel fission designs, and cooperates elastic element, in compensation rack rails wheel and rack bar installation and operational process
Pitch error, it is ensured that the even running of vehicle improves the stress of the gear teeth in rack rails wheel and rack bar, reduces vehicle and route
Severe impact.
