Abstract

The utility model belongs to the technical field of city subway, particularly to a novel subway flat car, which solves the problem the existing various types of flat cars can not meet the requirements by city subway authority and subway operation. The novel subway flat car comprises a chassis, wherein the chassis comprises a middle beam, side beams, a corbel, a big/small cross beam, an end beam and a longitudinal auxiliary beam, the novel subway flat car is characterized in that the chassis is a steel welding structure, the middle beam and side beams adopt a fish belly shaped structure, and the middle beam is composed of middle section steel structure and case type structures at two ends. The utility model has the following beneficial effects: ensuring the requirements of strength and rigidity, leading the largest width of the novel subway flat car to be 2540mm, meeting the requirements by city subway authority and subway operation, and also meeting the application requirement applied centralized load bearing.

Description

The novel subway flatcar
Technical field
The utility model belongs to the technical field of city underground, is specifically related to a kind of novel subway flatcar.
Background technology
The current rail Market competition, and the city underground development is just in the ascendant.Have the various flatcar of runing now and manufacture and design according to GB146.1-1983 " full gauge railway vehicle gauge of the locomotive " on railway line, the car body broad can not satisfy the requirement of city underground gauge.The floor of existing flatcar is higher apart from rail level in addition, has surpassed subway platform, and is inconvenient at the subway platform handling goods.Therefore, existing various articulated car can not satisfy city underground and run requirement, needs development can meet the novel subway flatcar of city underground gauge and operation requirement.
Summary of the invention
The utility model provides a kind of later-model subway flatcar in order to solve the problem that the various flatcar of existing railway can not satisfy requirement of city underground gauge and metro operation requirement.
The utility model adopts following technical scheme to realize:
A kind of novel subway flatcar, comprise underframe, underframe comprises central sill, curb girder, sleeper beam, big needle beam, end carriage and vertical floor stringer, it is characterized in that described underframe is all steel welded structure, central sill and curb girder adopt fish belly shape structure, and central sill is made of the formed steel construction of centre and the box-structure at two ends.Underframe is provided with the end door.Bogie truck is H shape welding integral type rigid frame, axle box single stage suspension, the sharp Nore shock attenuation unit of suspension ring formula.
The utlity model has following beneficial effect: to the improvement of Undercarriage structure, guaranteed the requirement of the strength and stiffness of car body, making the utility model maximum width is 2540mm, has satisfied the subway boundary and has required and the metro operation requirement.The improvement of Undercarriage structure in addition makes this car can satisfy the utilization requirement that applies concentrated load.This car is provided with distolateral door on underframe, lenticular shaped riffled iron floor is adopted on the floor, also is fit to the transportation loose goods.This car bogie truck adopts H shape welding integral type rigid frame, axle box single stage suspension, the sharp Nore shock attenuation unit of suspension ring formula, when commercial operation speed is 100km/h, the reliability and the safety of vehicle utilization can be guaranteed, and the application force between wheel track, the abrasion that alleviate each several part can be effectively reduced.The utility model is applicable on subway line and moves, for dress steel, timber, one-tenth case goods, mechanical equipment and other items.

Fig. 2 is the lateral plan of Fig. 1
Fig. 3 is the birds-eye view of Fig. 1
Among the figure: 1-hitch, 2-bogie truck, 3-underframe associate member, 4-curb girder, 5-brake equipment, 6-are held door, 7-side door, 8-central sill, 9-subway gauge.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further.
The width of novel subway flatcar is by subway gauge requirement design, and maximum width is 2540mm.For the assurance floor is not more than 900mm apart from rail level height (empty wagons), and for satisfying the rigidity requirement of car body, the central sill 8 of underframe and curb girder 4 have all adopted fish belly shape structure.This car is all steel welded structure of underframe carrying, and underframe is formed by assembly weldings such as central sill, curb girder, sleeper beam, big needle beam, end carriage and vertical floor stringers, guarantees the requirement of the strength and stiffness of car body.For ease of assembling hook before No. 2 locomotives, central sill 8 is not single elongated formed steel construction, and the box-structure by the steel plate assembly welding has been adopted at its two ends.Be provided with end door 6 on the underframe, the structure of end door is similar to existing flatcar, and lenticular shaped riffled iron floor is adopted on the floor, also is fit to the transportation loose goods.Bogie truck 2 adopts H shape welding integral type rigid frame, the axle box single stage suspension, and the sharp Nore shock attenuation unit of suspension ring formula,
Figure GSA00000121175400021
The 650mm wheel when commercial operation speed is 100km/h, can guarantee the reliability and the safety of vehicle utilization.
