Description
Technical field
The invention belongs to field of track traffic, and in particular to a kind of tooth rail car bogie.
Background technology
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 on circuit engage, so as to fulfill the traction and braking of rolling stock, maximum climbing slope can be with
Reach 250 ‰.
Tooth rail car is also relatively more easy in the application of the field of mining such as some coal mines, is unable to reach the condition of carrying operation.
At present, rack drives device is generally wheel track and rack rails combination drive pattern, and major defect is shown：It is driven using two axis,
For two groups of wheels to being above respectively equipped with corresponding driving device, the equipment installed on bogie is various, complicated, and driving device
It is complicated, it needs to be equipped with special clutch switching device, the bodily form and weight are very big, cause bogie overweight, to circuit
Load it is also very big, every cost of vehicle and circuit is all very high.
Invention content
In view of the above-mentioned problems, the present invention is intended to provide a kind of can effectively reduce light weight, simplified bogie structure improves
The performance of bogie and the tooth rail car bogie of curve passing through passability.
The technical solution of the present invention that solves the problems, such as is：A kind of tooth rail car bogie, including framework, installation architecturally two
Group wheel pair, two groups of one group of wheel centerings are driving wheel pair, and another group is non-driving wheel pair；
The driving wheel to include drive shaft, by bearing with driving axis connection wheel, wheel relative drive shaft self-movement；
Interference fit is equipped with rack rails wheel in the drive shaft, and the driving for drive shaft to be driven to turn round is connected on the framework
Device.
Said program 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 using list is shaft-driven：It can save on an other axle
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 said program is to for wheel pair commonly used in the prior art.
Specifically, the driving device include seize bracket, mounted on the traction electric machine seized on bracket, with seize bracket
The gear-box of installation is fixedly connected with and is seized with drive shaft, pinion shaft and the 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 circuits
Rail bar, vehicle could be run.
Further, brake drum is equipped on the pinion shaft of gear-box and in drive shaft, brake drum is with seizing support
Frame is fixed.
Mode of braking is arranged using two staged braking, and brake drum and independent control are respectively provided on high speed shaft and slow-speed shaft.Braking
Drum is fixed with seizing bracket, and by vehicle, sink-float is not influenced up and down for brake drum work.
Further, the rack rails wheel include gear ring, with drive shaft interference fit installation gear hub, gear hub wing plate,
Positioned at gear hub lateral surface and the end cap of gear hub wing plate lateral surface；
It is circumferentially spaced on gear hub end face to have first through hole, it is circumferentially spaced on gear ring end face to have and first through hole
One-to-one second through-hole, on gear hub wing plate end face it is circumferentially spaced have lead to the one-to-one third of first through hole
Hole, the end face of the gear hub, the end face of gear ring and gear hub wing plate end face three docking, gear ring are located at gear hub and gear
Between hub wing plate, and first, second, third through-hole is aligned；Gear hub, gear ring, gear hub wing plate, end cap by fastener successively
It is fixedly connected, first through hole, the second through-hole, third through-hole and end cap madial wall surround to form individual cavities after connection, the sky
Intracavitary is equipped with elastic element, which abuts simultaneously with a longitudinal end of first, second, third through-hole, elasticity
The other end of element abuts simultaneously with another longitudinal end of first, second, third through-hole.
In said program, the effect of end cap is sealing, and the effect of gear hub wing plate is to transmit torsion.
The split of rack rails wheel 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 taken turns in rack rails wheel and rack bar
The stress of tooth reduces the severe impact of vehicle and circuit.
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 is identical with the longitudinal end shape of first, second, third through-hole.
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 longerons, is set to longeron both ends and by the connection of two longerons
End carriage, the intermediate transverse girder for being set to longeron central region, during the distance between intermediate transverse girder and the axle of non-driving wheel pair are less than
Between the distance between crossbeam and drive shaft.
As a result of single shaft-driven structure, driving wheel is more than non-driving wheel pair to the weight of that side, for axis weight
Mean allocation, above-mentioned framework use asymmetrical structure type.
The present invention remarkable result be：
1. uniaxial rack drives can effectively reduce light weight, simplify bogie structure, so as to alleviate the list of vehicle and circuit
Position load, the manufacture of vehicle and circuit, with and maintenance cost be greatly reduced.Also it can shorten wheelbase, improve the performance of bogie
And the curve negotiating of 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, so as to ensure full line rack rails wheel drive.
3. the split of rack rails wheel designs, and coordinates 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 circuit
Severe impact.
