Description
Technical field
The present invention relates to a kind of jumbo chassis to hang girder construction, belongs to vehicle body of railway vehicle design field.
Background technology
Railcar equipment installation at present uses chassis suspending way, and chassis suspending way is divided into floor bearing and side
Load bearing beam two ways, floor bearing mode due to reasons such as vibration equipments, riding comfort is influenceed it is relatively large, and over the ground
Plate intensity requirement is higher to be unfavorable for car body lightweight, so the suspending way of side bar carrying at present is using more.
The equipment hanging beam that side bar hanging uses has various ways, but urban rail transit vehicles chassis apparatus hanging at present
Some drawbacks be present in beam：When hanging heavier equipment, it is difficult to meet strength and stiffness requirement using aluminium alloy hanging beam, generally adopts
With carbon steel structure beam, and carbon steel structure is for aluminium alloy structure, not only weight increase, and is difficult to avoid welding from lacking
Fall into；When hanging jumbo, often occur the situation that rigidity and weight can not be taken into account, transverse beam rigidity deficiency, Oscillation Amplitude compared with
Greatly, short life；When train impacts, region of stress concentration is easily cracked, and risk of breakage increase, service life drops significantly
It is low.The present invention proposes a kind of new equipment hanging beam section bar section struction, from the intensity for meeting to hang jumbo simultaneously
Set out with the aluminium alloy hanging beam angle of rigidity, the new equipment hanging beam can effectively avoid the generation of risk, increase bottom
The service life of frame crossbeam.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of jumbo chassis to hang girder construction, the jumbo chassis
Hanging beam structure loading capacity is big, technique is simple, can effectively avoid the generation of risk, increases the service life of body transom.
In order to solve the above-mentioned technical problem, jumbo chassis of the invention hanging girder construction includes hanging beam body, hangs
Drop in beam body both ends are provided with side bar connecting hole, are provided with stiffened panel in hanging beam body, hanging beam body side is hung provided with several
Hang mounting seat, it is described hanging mounting seat include flat board, hang plate, flat board side, hang plate side with this body sidewall of hanging beam
Connection, flat board opposite side are connected with hang plate opposite side, and hang plate is arranged on below flat board, and flat board is provided with screwed hole, are tilted
Plate is provided with fabrication hole, and the screwed hole and fabrication hole are on the same line.
The stiffened panel is inclined in hanging beam body.
The flat board is integrally formed with hang plate.
The hanging mounting seat is integrally formed with hanging beam.
The fabrication hole size is more than screwed hole size.
Girder construction is hung using this jumbo chassis, there is advantages below：
1st, the present invention has the characteristics that loading capacity is big, technique is simple, avoids welding, interface flexible, versatility good, and leads to
Static strength, mode and Calculation of Fatigue Life are crossed, can be widely applied to field of track traffic, providing safety for equipment under car can
Lean on, mounting means easy to maintenance.
1st, due to being provided with stiffened panel in hanging beam body, the intensity of equipment hanging beam is substantially increased.
2nd, because hanging beam body side is provided with several hanging mounting seats, hanging mounting seat includes flat board, hang plate, put down
Plate side, this body sidewall is connected with hanging beam for hang plate side, and flat board opposite side is connected with hang plate opposite side, and hang plate is set
Put below flat board, flat board is provided with screwed hole, and hang plate is provided with fabrication hole, and hanging mounting seat is carried out using this sample loading mode
Strengthen, for hanging jumbo, the hanging holder structure than simply using a level board improves the intensity of hanging, extended
Service life, the reliability of hanging beam body is effectively increased, train operational safety greatly improved.
