Description
Technical field
Bogie technique field is used the invention belongs to rail traffic vehicles, and in particular to one kind can significantly extend wheel Xuan
The low-floor light rail vehicle of wheel cycle and wheel service life is with new non-powered bogie.
Background technology
Light rail vehicle with 70% low-floor is functional, cost is relatively low, can have than 100% low-floor light rail vehicle higher
Overall trip speed and Technical Economy.Domestic and international existing 70% low-floor light rail vehicle is the communicating structure in low-floor region in the middle of realizing,
Non-powered bogie under its intermediate module uses independently rotating wheel structure, by axle bridge or shaftless bridge using concave
Structure reduces floor level, due to same axle bridge（Or axis）On two wheels can independently rotate, do not possess wheel it is right
The intrinsic self- steering performance realized by longitudinal Creep Forces, cause the bogie presence with independently rotating wheel to keep away
The flange wear phenomenon (such as Fig. 1) exempted from.On the one hand, flange wear significantly shorten wheel tread Xuan and repair the cycle, and frequent Xuan takes turns pole
The earth increased vehicle maintenance workload, significantly shorten elastic wheel service life；On the other hand, mechanism of independent wheel bearing and axle bridge
Complex structure, maintenance cycle is short, reliability is poor.Practice have shown that, the general bogie with independently rotating wheel can reach
The wheel Xuan cycles of repairing be only 2.5 ten thousand to 4.5 ten thousand kilometers, which greatly improves vehicle working service cost, reduce low land
The operation grade of plate light rail car.
In addition, existing low-floor light rail bogie, or secondary spring transverse direction span is too small, it is necessary to set up anti-side rolling
Torsion bar arrangement, increases vehicle cost and maintenance difficulties；Using full rubber secondary spring, service life is short, and vehicle performance is poor；
The Position Design of secondary spring it is too high, reduce the guest room space of vehicle, the spatial impression of vehicle interior is deteriorated.
The content of the invention
To solve existing 70% low-floor light rail vehicle independent wheel bogie wheel rim eccentric wear, tread Xuan, to repair mileage too short,
And independently rotating wheel axle bridge and bearing arrangement complexity, the problem of poor reliability, it is an object of the invention to：Asked for above-mentioned
Topic, there is provided a kind of new wheel for being used for 70% low-floor light rail vehicle intermediate module is to formula non-powered bogie.
For achieving the above object, the present invention provides a kind of 70% low-floor light rail vehicle intermediate module and takes turns non-to formula dynamic
Power bogie, including the connection of framework, wheel set axle box device, single stage suspension device, secondary suspension device, bogie and car body is filled
Put, it is characterised in that：Secondary spring in secondary suspension device is arranged on framework outside and sinks to inside truck side sill, takes turns to axle
Wheel in case apparatus by intermediate axle and by the wheel of left and right two that interference fit is fitted in intermediate axle two ends to constituting.
Described truck side sill middle part is in recessed cantilever shape, and recessed cantilever is provided with the sunk type peace of secondary spring
Dress hole, two crossbeams use the curb girder of seamless steel pipe, framework to be located at wheel inner side, and truck side sill is box welding structure, overall
Framework on cover middle part and be provided with two circular holes that secondary spring sinks to, and strengthened by round steel pipe, to ensure secondary spring
Support strength.
Described secondary spring is by helical steel springs and is placed in that top multilayer rubber spring is compound to be constituted.
The present invention is arranged on framework outside and sinks to inside truck side sill by secondary spring, increases the horizontal stroke of secondary spring
To span, it is to avoid use anti-side rolling torsion rod, while the height due to secondary spring away from rail level declines again, guest room space is increased；
Wheel in wheel set axle box device is to being fitted in the wheel of left and right two at intermediate axle two ends by intermediate axle and by interference fit
Composition, the wheel has intrinsic self-steering characteristics to structure, so avoids the problem of independently rotating wheel flange wear, real
Proof is trampled, the Xuan cycles of repairing of wheel tread bring up to 90,000 to 100,000 kilometers, also make while significantly improving car operation economy
Low-floor light rail vehicle has more preferable anti-Derailment Safety.

Specific embodiment
Embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1,70% low-floor light rail vehicle involved in the present invention generally comprises the first motor-car module 1, intermediate module
2nd, the second motor-car module 3, first end power truck 4, middle non-powered bogie 5 and the second end power truck 6.The
The top of one end power truck and the second end power truck is floor area high, between two power trucks and non-dynamic
Power bogie top is the low-floor structure in the insertion of longitudinal direction of car direction.
As shown in Figure 2 and Figure 3, existing vehicle technology uses independent axle Biodge device 7, and the floor level of intermediate module is general
For 350mm to 380mm；Using wheel set axle box device 8, floor level is arrived new non-powered bogie of the present invention for 480mm
500mm, passenger is met in low-floor region barrier free accessibility by setting 6 ° to 10 ° of slope at intermediate module floor two ends
Requirement, the size on slope is related to the size of used wheel diameter, and wheel diameter is generally 580mm to 660mm, too small
Wheel diameter is unfavorable for that vehicle is carried, derail safety and railway maintenance.
As shown in Figure 4, Figure 5, the specific embodiment of the invention includes framework, wheel set axle box device, single stage suspension device, two
Be the attachment means of suspension arrangement, bogie and car body, framework is steel plate die mould welding structure, it is main include two curb girders 18,
Two main beams 20, two butt beams 21, the middle part of truck side sill 18 is in recessed cantilever shape, and it is bullet that recessed cantilever is provided with two
The sunk type mounting hole 19 of spring, the horizontal span that this structure increases secondary spring avoids using anti-side rolling torsion rod, at the same again by
Height in secondary spring 12 away from rail level declines two and increased guest room space；Two crossbeams 20 use seamless steel pipe, reduce weldering
Connect workload；Can architecturally be needed that hydraulic or aeriality brake unit device are installed according to vehicle, and be set when needing
The backstop of magnetic rail braking device, the curb girder of framework is located at wheel inner side.Wheel set axle box device includes wheel to 8 and axle box device 9, wheel
8 wheels 21 of left and right two being fitted on axletree by intermediate axle and by interference are constituted.Single stage suspension device 10 is circular cone
Shape multilayer rubber spring, it is simple structure, safe and reliable, and manufacturability is good, top and the framework of single stage suspension device 10 pass through
Bolt-connection, bottom is coupled with axle box device 9 with bolt and pressing plate.Secondary spring device 12, two is that vertical damper 13, two is
Lateral damper 14, horizontal backstop 15 and vertical backstop 16 constitute the secondary suspension device of bogie.
Bogie is symmetrically arranged at the middle part of bogie with the coupling arrangement 17 of car body, is obtained on one end and frame apparatus 11
Drawing pull bar seat connection, the other end couples with intermediate module 3, for transmitting the tractive force between bogie and car body and braking
Power.
