Abstract
Originally utility model is made to disclose a kind of low-floor tramcar driver element, the driver element arrangement form is at home and abroad to propose and use first.The driver element uses traditional wheelsets structure, is the more preferable requirement for adapting to low-floor tramcar comfortableness, and wheel uses elastic wheel structure, using small diameter wheel, to reduce wheel-rail impact, reduction noise.Gear train assembly is arranged in wheel to inner side, and side is by box bearing axle-hung suspension on axletree, and opposite side and motor connection, motor are arranged in wheel laterally outer side position, and being hung on together with motor on framework, and motor is with wheel to arrangement arranged in parallel.Gear train assembly uses parallel-gear drive structure.Using reel brake disc.Pass through these structure designs so that the novel drive unit has preferably continued track transportation industry conventional art, research and develop speed, manufacturing cost is relatively low.
Description
Technical field
Originally utility model is related to a kind of low-floor tramcar driver element, be rail traffic vehicles novel drive unit
Arrangement form, motor arrangement form parallel and electric machine external with axletree, the low-floor that car body middle part is reserved with this is empty
Between, meet the requirement of urban rail transit vehicles low-floor.The driver element is particularly suitable for use in 70%, 100% low-floor city
The use of rail traffic vehicles, at home and abroad rail traffic vehicles are to use first to the driver element arrangement form.
Background technology
To realize tramcar 70%, 100% low-floor, tramcar power car bogie low floor technology is especially weighed
Will, power car bogie both domestic and external each tool spy in wheel shaft pattern and the number of axle, the suspension pattern of motor, the selection of the kind of drive
Color, structure type is varied.
The topmost difference of low-floor tramcar bogie technique is in the arrangement of drive device, current tramcar
Technology can be divided into by wheel：Traditional wheelsets technology, independent wheel wheel are to two kinds of technologies.Traditional wheelsets are compared with independent wheel wheel pair
Advantage and disadvantage are as follows：
A) traditional wheelsets
Traditional wheelsets technology maturation, simple in construction, reliability is high.By reducing radius of wheel, you can realize vehicle low land
Plate, is limited by installing space limited.But due to realize low-floor requirement, the wheel compared with small-wheel-diameter must be used, due to wheel
Wheel footpath is small, more sensitive to the irregularity of circuit, and the stationarity of vehicle is poor；The wheel tread of small-wheel-diameter is easily abraded；Wheel track connects
Tactile stress is higher, and the abrasion of tread are fast, and the wheel replacement cycle is shorter.
B) independent wheel wheel pair
Independent wheel wheel is to being substituted by the axletree cancellation of traditional wheelsets, or using recessed axle bridge, and wheel is empty to inner side
The space gone out is set to floor compartment passageway, and due to no axletree, left and right wheel " decoupling ", each of which is independent in wheel
The heart rotates.Due to independent wheel bogie technical sophistication, price is high, many problems is exposed in utilization, such as wheel is fast
Speed abrasion, flange wear phenomenon are protruded, wheeling edge wearing is serious, and the Xuan wheel cycles are significantly shorter than traditional wheelsets, and the wheel replacement cycle is short,
And derailing tendency is higher than traditional wheelsets.Although many tramcar manufacturers, horizontal by independent wheel by coupling technique now
Or Longitudinal data gets up, but still the problems such as flange wear can not be efficiently solved, bogie structure is also resulted in increasingly complex.
Tramcar by motor relative to wheel to arrangement form can then divide into：Motor is longitudinally arranged driver element, electricity
Machine is arranged vertically driver element, hub direct-drive motor driver element, motor lateral arrangement driver element.
Motor is longitudinally arranged driver element because electrical axis are vertical to axis with taking turns, therefore transmission system gear must be set
Angular wheel is calculated as, processing, assembly precision require high, and driver element complicated integral structure, cost is higher, and current driver element is also
Must entirety dependence on import.
Although the vertical arrangement driver element electrical axis of motor with wheel to diameter parallel, due to motor be arranged in wheel to
Surface, the integral layout of bogie is more complicated, and motor can take part vehicle body passenger seat space, influences seat cloth
Put, while motor is nearer apart from floor, noise-reducing design must be considered emphatically, cost is higher, and current driver element must also be overall
Dependence on import.
Hub direct-drive motor driver element is due to all unsprung weights of motor weight, and wheel track run action is firmly larger,
Motor must bear larger wheel-rail impact.
Motor lateral arrangement driver element due to electrical axis with wheel to diameter parallel, gear train assembly using it is ripe,
Reliable parallel-gear drive structure, processing, assembling skill identical with the arrangement form of the most of driver element of track transportation industry
Art is highly developed, and driver element autonomous Design and can realize production domesticization.
By the description of background above technology as can be seen that the current all transmissions of tramcar bogie driver element technology
System is arranged in lateral wheel, and motor is arranged in lateral wheel, and bogie frame is built in wheel to inner side, with track transportation industry
(locomotive, motor-car, subway) prior art is completely contradicted, and structure is more complicated, and research and development, manufacturing cost are higher, and existing rail at present
Electric car driver element overwhelming majority palpus dependence on import, foreign countries strictly block to driver element technology, domesticize more difficult.
Utility model content
Originally make the purpose of utility model be to provide a kind of low-floor tramcar driver element, be that a kind of support track is handed over
The driver element of current industry (locomotive, motor-car, subway) prior art (transmission system and motor are arranged in wheel to inner side) exploitation,
The driver element arrangement form is at home and abroad to propose and use first.
In order to achieve the above object, utility model embodiment is originally made to provide a kind of low-floor tramcar driver element, bag
Include：
The driver element is assemblied by wheel, axletree, motor, gear train assembly, brake disc, axle box, and gear is passed
Dynamic system is with wheel to assembling；Motor is assembled with gear-box, the assembling of driver element is completed, because motor uses frame
Outstanding structure, thus by suspension device of motor by motor suspension on framework, wheel to middle part removing unit brake apparatus and
The space that gear train assembly takes, longitudinal space is left to floor compartment；Simultaneously because causing car using small diameter wheel
Railway carriage or compartment floor level is further reduced, and vertical space is left to floor compartment, can meet low-floor tramway carriage floor
Space requirement.
Further, the gear train assembly is arranged in wheel to inner side, side by box bearing axle-hung suspension in
On axletree, opposite side and motor connection, motor are arranged in wheel laterally outer side position, and hang on together with motor framework
On, motor is with wheel to arrangement arranged in parallel.
Further, gear train assembly uses parallel-gear drive structure.
Further, the brake disc is reel brake disc.
