Abstract
The utility model discloses a low floor urban rail vehicle. The low floor urban rail vehicle comprises a bullet train and a middle trailer at the front end and the rear end, wherein a steering frame of the middle trailer is an independent wheel set steering frame; a train body of the bullet train comprises a short train body and a long train body which are connected; the short train body is connected with the long floating train body by hinging at the end of the vehicle; the short train body serves as an independent cab; the long train body serves as a passenger region; a power steering frame of the bullet train is arranged below the independent cab; and a traction drive system of the power steering frame of the bullet train is longitudinally arranged on a side beam. According to the scheme, by adopting the conventional small-diameter wheel set power steering frame, and 100% low floor vehicle is achieved by utilizing 70% low floor technology and cost for suspending the traction drive system onto a cross beam originally, so that the purposes of reducing the technical risk and the cost are achieved.
Description
Technical field
The utility model relates to a kind of low floor city rail vehicle, belongs to especially the rail vehicle truck technical field.
Background technology
The mainstream technology that realizes at present low floor vehicle has two kinds, and a kind of is that motor car bogie is the right motor car bogie of tradition wheel, and trailer bogie is mechanism of independent wheel pair, and another kind is that trailer bogie all adopts mechanism of independent wheel pair.The bogie technique maturation that the tradition wheel is right, productive costs is low, and present domestic low floor all adopts this technology, but the floor on bogie truck top can't realize low floor, so can only accomplish at present 70% low floor rate in the first method.And mechanism of independent wheel is not to owing to there being an axletree, can significantly reduce floor, therefore moving trailer bogie all adopts the right technology of mechanism of independent wheel can reach 100% low floor rate, but mechanism of independent wheel is to lacking vertical Creep Forces, can not as the tradition wheel to have from leading function, if particularly be used for motor car bogie, control accuracy to motor requires very high, otherwise easily derailing, domestic also do not have a proven technique, and technical risk and cost are all very high.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the above-mentioned shortcoming of prior art, and a kind of low floor city rail vehicle is provided, and can reach 100% low floor rate.
In order to solve above technical matters, a kind of low floor city rail vehicle that the utility model provides, the motor-car that comprises the rear and front end, middle trailer, the bogie truck of trailer is that mechanism of independent wheel is to bogie truck in the middle of described, it is characterized in that: the car body of described motor-car is formed by connecting by short car body and long vehicle body, described short car body links together by the hinged long vehicle body with floating of car end, described short car body is as independent driver's cab, described long vehicle body is as passenger zone, the power truck of described motor-car is arranged at the below of independent driver's cab, and the traction drive of the power truck of described motor-car vertically is arranged on the curb girder.
Further, the wheel diameter of the power truck of motor-car is 600mm-660mm, and place, the passageway height of floor from rail top of described trailer is 350mm, and place, motor-car passageway height of floor from rail top is 400mm.
Further, the two ends of place, motor-car passageway floor are excessive by little slope.
In order both to realize 100% low floor, reduce again technical risk and cost, having adopted a kind of motor car bogie is that minor diameter tradition wheel is right, and trailer bogie is the right low floor vehicle of mechanism of independent wheel.Although what motor car bogie adopted is that the tradition wheel is right, but by reducing its diameter, the simultaneously former traction drive that is positioned at horizontal layout on the bogie truck crossbeam moves on on the curb girder vertically to be arranged, and with the location arrangements of power truck under independent driver's cab, still can reach the effect of fine low floor, therefore when having realized 100% low floor, evaded again motor car bogie and adopted technical risk and the cost of mechanism of independent wheel to bringing.
This technology realizes 100% low floor by 70% technology and cost dexterously, and maturation, reliable and economic characteristics are arranged, and must good prospect be arranged in 100% low floor market.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model low floor city rail vehicle structural representation.
Fig. 2 is power truck structural representation of the present utility model.
The specific embodiment
The low floor city rail vehicle of the present embodiment, as shown in Figure 1, the motor-car, the middle trailer 1 that comprise the rear and front end, the bogie truck of middle trailer 1 is that mechanism of independent wheel is to bogie truck 5, the car body of motor-car is formed by connecting by short car body 2 and long vehicle body 3, short car body 2 links together by the hinged long vehicle body 3 with floating of car end, short car body 2 is as independent driver's cab, long vehicle body 3 is as passenger zone, the power truck 4 of motor-car is arranged at the below of independent driver's cab (short car body 2), as shown in Figure 2, the traction drive 6 of the power truck of motor-car vertically is arranged on the curb girder.In this example, the wheel diameter of the power truck of motor-car is 660mm, and place, the passageway height of floor from rail top of trailer is 350mm, and place, motor-car passageway height of floor from rail top is 480mm.The two ends of place, motor-car passageway floor are excessive by little slope.7 is floor among Fig. 1.
The motor car bogie of this low floor city rail vehicle adopts small-diameter wheels pair, and the traction drive that will originally be placed on the crossbeam moves on on the curb girder, and bogie truck centre portion space can allow out, the recessed low floor that forms of car body floor face.This low floor city rail vehicle can reach floor, 100% ground dexterously.Car body on the bogie truck is independently become a short car body, link together by the hinged long vehicle body with floating of car end, can rotate flexibly between the car body, train can pass through very little curve.And the independent short car body in two ends just can be used as driver's cab, and passenger zone can be accomplished completely low floor.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
