Description
Technical field
The present invention relates to a kind of overhead rail vehicle running gear, for the vehicle bottom installed in empty rail vehicle, belongs to
Technical field of rail traffic.
Background technology
Overhead rail vehicle belongs to a kind of rail vehicle type of innovation at home, and the drive device of vehicle is located at track box
In ellbeam, and it is that the device of this vehicle power supply is an electromagnetism car for being located at vehicle tail, this electromagnetism car is without drive device, entirely
Portion is located in track girder.Therefore, a kind of convenience, practicality are designed and the electromagnetism car with bigger receiving space on car can be made to walk luggage
It is set to for necessity.
The content of the invention
The goal of the invention of the present invention is：For above-mentioned problem, there is provided a kind of overhead rail vehicle running gear.
The technical solution adopted by the present invention is such：
A kind of overhead rail vehicle running gear, including wheel hub, travelling wheel and axle, in addition to car body connecting plate, the car body connect
Fishplate bar both sides respectively symmetrically open up the axis hole of horizontal blind hole form, and axle one end installation wheel hub and travelling wheel, the other end is with mistake
The fit system that is full of is arranged in axis hole and positioned by axle terrace of appearing on the stage.
Above-mentioned technical proposal employs the unique way that short axle is connected with car body connecting plate, has following characteristic：
1st, installed between short axle and car body connecting plate using interference fit, simple in construction, assembling is very convenient；Can be with
More accommodate equipment on car.
2nd, compared to major axis traditional before, short axle adds up very convenient, and manufacturing cost is relatively low；
3rd, the car body connecting plate of short axle and vehicle bottom is directly connected to, and reduces the center of gravity of car body, security is higher；
4th, by way of axle appears on the stage terrace positioning, the distance between both sides travelling wheel can be controlled well.
In above-mentioned technical proposal, the weight transmitting path of car body is：Car body-car body connecting plate-axle-bearing-wheel hub-traveling
Wheel-to-rail road.When vehicle is run, axle does not rotate, and travelling wheel rotates.Therefore, gap is used between tapered roller bearing internal ring and axle
Coordinate, between taper roll bearing outer ring and wheel hub using interference fit, so as to ensure axle, bearing, wheel hub mounting surface transporting
It is injury-free during row, increase the service life.
Preferably, the wheel hub is mounted on an axle by a pair of taper roll bearings, wheel hub inner side and taper roller axle
Hold inner side to be sealed by inner seal structure and carry out axially position by the step surface on axle, rolled on the outside of wheel hub with circular cone
Seal simultaneously axially position by outer side seal structure on the outside of sub- bearing.
Preferably, the inner seal structure includes sealing ring two and sealing ring three, sealing ring two is installed by bolt
In wheel hub medial surface, sealing ring threeway crosses boss inner ring and pushes against taper roll bearing and then positioned by axle terrace of appearing on the stage,
The lap of sealing ring two and sealing ring three is further sealed by labyrinth structure.
Preferably, the outer side seal structure includes sealing ring one and closure, the sealing ring one is pacified by bolt
Mounted in wheel hub lateral surface, closure pushes against taper roll bearing by boss inner ring and then carried out by bolt installed in axle outer end
Axially position, the lap of sealing ring one and closure are further sealed by labyrinth structure.Further preferably, the sealing
Adjusting pad is also set up between boss inner ring and taper roll bearing on the inside of covering, adjusting pad is manufactured using match grinding mode, according to axle
Hold the clearance measured after assembling and determine its thickness, to ensure end-play.Closure is brought into close contact with axial end, ensures labyrinth knot
The axial direction of structure by clamping stagnation, is not coordinated using small―gap suture between the boss inner ring and axle of closure, ensures the radial direction of labyrinth structure not
By clamping stagnation.
In above-mentioned technical proposal, to have a step to be caught in wheel hub cylindrical for sealing ring one and sealing ring two cylindrical, realizes close
The radial direction of seal is accurately positioned, and ensures labyrinth structure radially not by clamping stagnation.
Preferably, the replacing of travelling wheel is facilitated by bolt detachable connection between the wheel hub and travelling wheel.Enter
One step is preferred, and the wheel hub manufactures for aluminium alloy, and the travelling wheel is that rubber adds metal to manufacture.
Brief description of the drawings
Fig. 1 is the overall schematic of the present invention.
Fig. 2 is the partial sectional view of the present invention.
Marked in figure：1 is closure, and 2 be sealing ring one, and 3 be bearing one, and 4 be wheel hub, and 5 be travelling wheel, and 6 be bearing two,
7 be sealing ring two, and 8 be sealing ring three, and 9 be axle, and 10 be adjusting pad, and 11 be car body connecting plate, and 12 be bolt.
