Abstract
The invention relates to a suspended beam structure for a heavy equipment chassis. The suspended beam structure comprises a suspended beam main body, wherein boundary beam connecting holes are formed in the two ends of the suspended beam main body; a ribbed plate is arranged in the suspended beam main body; a plurality of suspending mounting bases are arranged on one side of the suspended beam main body; each of the suspending mounting bases comprises a horizontal plate and an inclined plate; one side of the horizontal plate and one side of the inclined plate are both connected with a side wall of the suspended beam main body; the other side of the horizontal plate is connected with the other side of the inclined plate; the inclined plate is arranged under the horizontal plate; a threaded hole is formed in the horizontal plate; a technical hole is formed in the inclined plate; and the threaded hole and the technical hole are located in a same straight line. The suspended beam structure is high in loading weight and simple in technique, is capable of effectively avoiding risk, and is capable of prolonging the service life of a chassis beam.
Description
Technical field
The present invention relates to girder construction hung by a kind of jumbo underframe, belong to vehicle body of railway vehicle design field.
Background technology
Railcar equipment is installed and is adopted underframe suspending way more at present, and underframe suspending way is divided into floor bearing and side
Load bearing beam two ways, floor bearing mode, due to reasons such as vibration equipments, affects relatively large on riding comfort, and over the ground
Plate intensity requirement is higher to be unfavorable for car body lightweight, so the suspending way application that current side bar carries is more.
The equipment hanging beam that side bar hanging adopts has various ways, but current urban rail transit vehicles chassis apparatus hanging
There are some drawbacks in beam：When hanging heavier equipment, it is difficult to meet strength and stiffness requirement using aluminium alloy hanging beam, generally adopts
Use carbon steel structure beam, and carbon steel structure is for aluminium alloy structure, not only weight increases, and be difficult to avoid welding to lack
Fall into；During hanging jumbo, situation that rigidity and weight can not take into account often occurs, transverse beam rigidity is not enough, and Oscillation Amplitude is relatively
Greatly, short life；When train occurs impact, easily crackle in region of stress concentration, and risk of breakage increases, and service life drops significantly
Low.The present invention proposes a kind of new equipment hanging beam section bar section struction, meets the intensity hanging jumbo from simultaneously
Set out with the aluminium alloy hanging beam angle of rigidity, this new equipment hanging beam can be prevented effectively from the generation of risk, increase bottom
The service life of frame crossbeam.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of jumbo underframe to hang girder construction, this jumbo underframe
Hanging beam structure loading capacity is big, process is simple, can be prevented effectively from the generation of risk, increases the service life of body transom.
In order to solve above-mentioned technical problem, the jumbo underframe hanging girder construction of the present invention includes hanging beam body, hangs
Drop in beam body two ends are provided with side bar connecting hole, and hanging beam is originally provided with stiffened panel in vivo, and hanging beam body side is provided with several and hangs
Hang mounting seat, described hanging mounting seat includes flat board, hang plate, flat board side, hang plate side all with this body sidewall of hanging beam
Connect, flat board opposite side is connected with hang plate opposite side, and hang plate is arranged on below flat board, and flat board is provided with screwed hole, tilt
Plate is provided with fabrication hole, and described screwed hole is with fabrication hole on the same line.
Described stiffened panel is inclined at hanging beam, and this is internal.
Described flat board and hang plate are integrally formed.
Described hanging mounting seat is integrally formed with hanging beam.
Described fabrication hole size is more than screwed hole size.
Girder construction is hung using this jumbo underframe, there is advantages below：
1st, the present invention has that loading capacity is big, process is simple, the features such as avoid welding, interface flexible, versatility good, and passes through quiet
Intensity, mode and Calculation of Fatigue Life, can be widely applied to field of track traffic, are that under car, equipment provides safe and reliable, dimension
Protect convenient mounting means.
1st, because hanging beam is originally provided with stiffened panel in vivo, substantially increase the intensity of equipment hanging beam.
2nd, hang mounting seat because hanging beam body side is provided with several, hanging mounting seat includes flat board, hang plate, puts down
Plate side, hang plate side are all connected with this body sidewall of hanging beam, and flat board opposite side is connected with hang plate opposite side, and hang plate sets
Put below flat board, flat board is provided with screwed hole, hang plate is provided with fabrication hole, using this sample loading mode, hanging mounting seat is carried out
Strengthen, for hanging jumbo, improve the intensity of hanging, prolongation than the simple hanging holder structure using a horizontal plate
Service life, effectively increases the reliability of hanging beam body, train operational safety is greatly improved.
