Description

A kind of rubber wheel drive wheel pair
Technical field
This practicality belongs to tire art, is specially a kind of rubber wheel drive wheel pair.
Background technology
Traditional guideway vehicle (as modern tram) has vehicle marshalling field freight volume large, adopt electric traction noise low, emission-free discharge, entrance is low is convenient to advantages such as getting on or off the bus, it is a kind of urban public transport vehicle extensively favored, but its bogie truck adopted all adopts steel wheel, and two, a left and right steel wheel axle links up to ensure that axletree is positioned at wheel center, the floor of vehicle will be higher, and left and right wheels rotor speed can be consistent, can not active adjustment track, therefore needing to travel is being laid on rail specially, the running orbit of guideway vehicle is controlled by rail.
But in actual applications because steel rail laying can bring higher cost, destroy the adverse effects such as road surface, guideway vehicle volume is larger simultaneously, therefore tramway train in the region of the new planning such as suburb or high and new technology industrial development zone, can only not be suitable for ground communications in urban district, tramway train is difficult to a large amount of universal.Though and have at present about the Patents of guideway vehicle application with road surface, urban district, its bogie truck adopted all adopts metal wheel pair, and needs to travel and be laid on rail specially, and steel rail laying can bring higher cost, destroy the adverse effects such as road surface; Simultaneously the dimensional footprint of independent wheelset is large, and when being applied to guideway vehicle, shared volume is comparatively large, is unfavorable for that guideway vehicle is at city ride.
practical content
In order to solve the problems of the technologies described above, this practicality provides a kind of rubber wheel drive wheel pair, this independent wheels structure can meet the requirement that low floor city railway vehicle reduces height of floor from rail top, improve the safety factor of guideway vehicle, curve passing through can be improved again and pass through performance, reduce the volume of guideway vehicle, make guideway vehicle convenient run on urban district.
For realizing above-mentioned technical purpose, the concrete technical scheme that this practicality is taked is, a kind of rubber wheel drive wheel pair, and comprise rubber wheel, brake equipment, axle bridge and driving device, described brake equipment is positioned at the inner side of rubber wheel; Described axle bridge comprises the main body of the middle recessed structure that takes the shape of the letter U and main body two ends and is positioned at connecting portion on same axis; Described connecting portion is hollow structure; Described driving device comprises bearing axle box, break-in drive gearbox and axle drive shaft, described axle drive shaft is through the connecting portion of hollow structure, one end that axle drive shaft is positioned at axle bridge main body connects break-in drive gearbox, break-in drive gearbox drives drive shaft turns, the other end of axle drive shaft is fixedly connected with bearing axle box, and bearing axle box rotates under the transmission of axle drive shaft; The inside face of described bearing axle box is fixed on the outside face of hollow structure connecting portion, and the outside face of bearing axle box is provided with rubber wheel; Described rubber wheel runs under the drive of bearing axle box.
As the preferred technical scheme of this practicality, described brake equipment comprises brake disc and hydraulic braking clamp, and described brake disc is fixed on the wheel hub of rubber wheel, and described hydraulic braking clamp is connected with connecting portion interference fit.
As the preferred technical scheme of this practicality, between described axle drive shaft and break-in drive gearbox, spiral bevel gear is adopted to be in transmission connection.
As the preferred technical scheme of this practicality, each rubber wheel is all equipped with a break-in drive gearbox, and independent control between each break-in drive gearbox.
This practicality is relative to the advantage of prior art
1, adopt U-shaped axle bridge, realize reducing height of the carbody, improve the safety performance of guideway vehicle; The connecting portion at axle bridge two ends is hollow structure simultaneously, and after axle drive shaft runs through the connecting portion of hollow structure, two ends connect break-in drive gearbox and bearing axle box respectively, and compared to existing technology, driving device is installed on the outside of tire, saves the space of independent wheelset.
2, on each wheel all with break-in drive gearbox, separate between each break-in drive gearbox, centre is not communicated with, about it, each comfortable axle drive shaft of two wheels drives lower independent rotation, than the advantage of the structure of existing automobile front-rear axle be, control wheel can be carried out by the speed discrepancy about ACTIVE CONTROL between two wheels to by straight line or curve driving, be convenient to vehicle and realize automatic tracking control.
In sum, the new type rubber wheel low floor vehicle adopting the rubber wheel drive wheel of this practicality right, can compatible existing city motor bus road surface, can have as traditional guideway vehicle again that freight volume is large, the feature of low-carbon environment-friendly, be a kind of ideal city ground public transport vehicle.Therefore, this practicality progressively can replace the city ground public transport instrument that city motor bus becomes main, market outlook are very good.

The cutaway view that a kind of rubber wheel of Fig. 2 drive wheel is right;
Rubber wheel 1, axle bridge 2, bearing axle box 3, break-in drive gearbox 4, axle drive shaft 5, hydraulic braking clamp 6, brake disc 7, car body 8 in figure.
Detailed description of the invention
In order to better explain the technical scheme of this practicality, make complete description below in conjunction with accompanying drawing 1 and accompanying drawing 2 and the technical scheme of embodiment to this practicality.
Embodiment
A kind of rubber wheel drive wheel pair according to Fig. 1 and Fig. 2, comprise rubber wheel 1, brake equipment, axle bridge 2, driving device, described axle bridge 2 comprises the connecting portion that the main body of the middle recessed structure that takes the shape of the letter U and main body two ends are positioned at the hollow structure on same axis; Described driving device comprises bearing axle box 3, break-in drive gearbox 4 and axle drive shaft 5; Described axle drive shaft 5 is through the connecting portion of hollow structure, and one end that axle drive shaft 5 is positioned at axle bridge 2 main body connects break-in drive gearbox 4, and the other end of axle drive shaft 5 is fixedly connected with bearing axle box 3; The inside face of described bearing axle box 3 is fixed on the outside face of hollow structure connecting portion, and the outside face of bearing axle box 3 is provided with rubber wheel 1; During vehicle operating, the zigzag tread patterns power of drive system is delivered on break-in drive gearbox 4, break-in drive gearbox 4 inside adopts spiral bevel gear to be laterally by propulsive effort direction transformation, then is delivered on bearing axle box 3 through axle drive shaft 5, and bearing axle box 3 drives rubber wheel 1 to run.Wherein, the break-in drive gearbox 4 zigzag tread patterns torque conversion transversely driving torque that can will pass over from driver for vehicle; About independent wheelset, two break-in drive gearboxs 4 are separate in addition, centre is not communicated with, than the advantage of the structure of existing automobile front-rear axle be, the floor in car body can be reduced, coordinate with foregoing axle bridge 2, make car body floor face to reduce below medium plane of wheel, make vehicle floor face lower than prior art; Each rubber wheel 1 is all furnished with a break-in drive gearbox 4, separate, the advantage of this structure is that same wheel can independently control the rotating speed of upper two rubber wheels 1 in left and right, control wheel can be carried out by the speed discrepancy about ACTIVE CONTROL between two rubber wheels 1 to by straight line or curve driving, be convenient to vehicle and realize automatic tracking control.
