Abstract
The invention relates to a middle chassis of a railway flatcar. The railway flatcar takes a certain place in domestic railway freight transportation over the years, but the middle chassis (or a small chassis) of the prior railway flatcar employs a box-shaped structure formed by two webs, an upper cover plate and a lower cover plate. The middle chassis comprises a crossbeam assembly (1), a middle beam assembly (2) and a corbel assembly (3); wherein the middle beam assembly comprises the web (4), a middle lower cover plate (5), a middle upper cover plate (6), an end part upper cover plate (7) and an end part lower cover plate (8); and the components forms a fully-enclosed beveled V-shaped structure. The middle lower cover plate (5) of the middle beam assembly is a cross-shaped arc plate on the whole; and the middle upper cover plate (5) is connected with the web (4) in a semi-insertion way. The middle chassis of the railway flatcar is capable of meeting the requirement on the railway flatcar strength and the bearing surface height for the transportation of overweight goods and is used as a fitting of the railway flatcar.
Description
Technical field:
the present invention relates to underframe in a kind of articulated car.
Background technology:
For many years, articulated car occupies a tiny space in the railway freight traffic of China
, but the box type construction that the middle underframe (or little underframe) of existing articulated car all adopts two blocks of webs and upper and lower cover plate to form, and load-carrying capacity is low; Underframe (or little underframe) central sill composition is generally the fish-bellied type structure in existing, and the discrepancy in elevation of middle part cartridge face and end cartridge face is big, can't effectively reduce the vehicle carrying surface; And the knuckle position of general totally-enclosed beveled structure adopts full plug-in type to be connected between web and middle part upper cover plate, is prone to the generation welding stress.Therefore underframe (or little underframe) can't satisfy the demand of overweight, big goods railway transportation in existing.
Summary of the invention:
the object of the invention provides underframe in a kind of extraordinary articulated car, and it is little to be used to overcome the load-carrying of common railway flatcar, defectives such as carrying surface, reach improve load-carrying, reduce the utilization cost, simplified design structure, the purpose of increasing work efficiency.To the problem of above-mentioned existence, for alleviating the nervous situation of railway transportation, increase work efficiency, underframe in a kind of articulated car that connects great underframe and little underframe is provided.
Above-mentioned purpose realizes through following technical scheme:
Underframe in
articulated car; Its composition comprises: crossbeam is formed, central sill is formed, sleeper beam is formed; Described central sill is formed the end and is connected crossbeam composition, middle part connection sleeper beam composition; Described central sill is formed and is comprised web, middle part upper cover plate, middle part lower cover, end upper cover plate and end lower cover, and described 4 webs link to each other with middle part upper cover plate, middle part lower cover, end upper cover plate and end lower cover, form totally-enclosed knuckle V-structure.
described articulated car; The middle part upper cover plate that described central sill is formed is whole cross arc plate; Adopt the semi-plug-in connection mode between described middle part upper cover plate and described end upper cover plate; The middle part upper cover plate that described central sill is formed is whole cross arc plate, adopts the semi-plug-in connection mode between described middle part upper cover plate and described end upper cover plate, on the described middle underframe 2 body center plates and 1 truck center plate is arranged; Link to each other with the little underframe of its underpart through described body center plate, link to each other with the great underframe on its top through described truck center plate.
Beneficial effect:
1. the present invention connect great underframe and little underframe in articulated car; Adopt the V-structure central sill to form; The truck center plate face that links to each other with great underframe is reduced with the discrepancy in elevation of setting one's heart card that links to each other with little underframe; The carrying surface that has reduced articulated car significantly is high apart from rail level, has enlarged bearing space and loading scope.
the present invention adopts four web structure; Improve the unit length load-carrying capacity of middle underframe, the bogie truck spacing of said flatcar is reduced, reduced said flatcar length over ends of body; Make said flatcar compact conformation, reasonable, the curve motion performance is more excellent.
the present invention adopts the semi-plug-in connection mode between web and middle part upper cover plate, has not only increased the Joint strenght of web and closing panel but also has avoided enclosure space and produce welding stress.
. the present invention adopts full-closed structure, and steel underframe is safeguarded in can realizing, has made things convenient for maintenance.
application of the present invention; The load-carrying capacity of the middle or small underframe of heavily loaded flatcar of multiple underframe formation is improved greatly; The heavily loaded flatcar carrying surface that has reduced multiple underframe formation is high apart from rail level; Made things convenient for the maintenance and the maintenance of steel underframe, said in the underframe The Application of Technology, the development of the heavily loaded flatcar that will constitute multiple underframe produces far-reaching influence.
Description of drawings:
accompanying drawing 1 is a main TV structure scheme drawing of the present invention.
accompanying drawing 2 is a plan structure scheme drawing of the present invention.
The specific embodiment:
Embodiment 1:
Underframe in
articulated car, its composition comprises: central sill forms 2, and the both sides that described central sill is formed connect crossbeam composition 1 respectively and form 2 with sleeper beam, and sleeper beam is formed 2 and is positioned at the middle part, and crossbeam composition 1 is positioned at both ends.
described central sill is formed and is comprised that web 4, middle part lower cover 5, middle part upper cover plate 6, end upper cover plate 7 and end lower cover 8 each parts form totally-enclosed knuckle V-structure.
Embodiment 2:
It is whole cross arc plate that underframe in
described articulated car, described central sill are formed middle part upper cover plate 5, and 4 of middle part upper cover plate 5 and webs adopt the semi-plug-in connection mode.
Claims (2)
1. underframe in the articulated car; Its composition comprises: crossbeam is formed, central sill is formed, sleeper beam is formed; It is characterized in that: described central sill is formed the end and is connected crossbeam composition, middle part connection sleeper beam composition; Described central sill is formed and is comprised web, middle part upper cover plate, middle part lower cover, end upper cover plate and end lower cover, and described 4 webs link to each other with middle part upper cover plate, middle part lower cover, end upper cover plate and end lower cover, form totally-enclosed knuckle V-structure.
2. underframe in the articulated car according to claim 1; It is characterized in that: the middle part upper cover plate that described central sill is formed is whole cross arc plate; Adopt the semi-plug-in connection mode between described middle part upper cover plate and described end upper cover plate; On the underframe 2 body center plates and 1 truck center plate are arranged in described, link to each other with the little underframe of its underpart, link to each other with the great underframe on its top through described truck center plate through described body center plate.
