Abstract
The utility model relates to a railway vehicle body side and top connecting section plate, which adopts an aluminum alloy hollow thin-wall extrusion section bar, and realizes lightweight design of an aluminum alloy vehicle body and automatic assembling and welding of vehicle body assembling and welding under the premise of meeting requirements of rigidity and strength parameters. The section plate is formed into an integrated structure by extrusion technology. The section plate is provided with a cambered inner plate and an outer plate, wherein the radians of the inner plate and the outer plate are not the same so as to form contours not mutually parallel; a plurality of continuous inclined rib plates are arranged between the inner plate and the outer plate; and the adjacent rib plates divide the inner space of the section plate into a plurality of triangles. The end parts where the section plates are connected with each other are provided with inserting sheets used for splicing. The top where the section plate is connected with a vehicle top of the railway vehicle or the side wall of the vehicle body is provided with a pair of lapping sheets used for lapping inwards and outwards.
Description
Technical field
The utility model relates to place, a kind of formation vehicle body of railway vehicle side roof part end angle bonded assembly profile plate, belongs to mechanical manufacturing field.
Background technology
The speed per hour of present domestic motor train unit has reached velocity stage more than 300 kilometers, and the high-speed cruising of guideway vehicle certainly leads to the designing requirement that takes into account rigidity of vehicle body intensity and lightweight structure.
The general aluminium alloy profile of light-duty car body of existing high-speed track vehicle, aluminium alloy extrusions generally adopts skeleton shell, slim material monoshell or hollow double hull configuration etc.This type of Light Aluminum Alloy section bar still can't reach unified on rigidity intensity and lightweight performance, therefore also exist certain difficult point in the design and use that realize the hot-short car body.
In addition, connect lightweight car body, car body underframe, practical problems such as also exist the connection structure complexity, easily deform after connecting for building.
The utility model content
Vehicle body of railway vehicle side roof part connection profile plate described in the utility model, its design goal is to address the above problem and adopts aluminium alloy hollow thin-walled extrudate, under the prerequisite that reaches the requirement of rigidity and intensive parameter, realize the light-weight design of aluminum alloy bodywork and the automation assembly welding of car body assembly welding.
For realizing above-mentioned design goal, described vehicle body of railway vehicle side roof part connection profile plate is to form integral structure by extrusion process.The difference with the prior art part is,
Described profile plate has the inner panel and the outside plate of arc, and the radian of inner panel and outside plate is inequality and form uneven each other appearance profile.
Be provided with a plurality of continuous diagonal bar plates between inner panel and outside plate, adjacent diagonal bar plate is divided into several triangles with the section bar inner space.
In the interconnective end of described profile plate, be provided with the inserted sheet that is used to peg graft.
Described profile plate and guideway vehicle roof or with car body side wall bonded assembly end, be provided with a pair of butt strip of a pair of inside and outside overlap joint.
As above-mentioned basic scheme, between outside plate and inner panel, form hollow cavity, thereby realize the light-weight design of profile plate itself.Inner chamber is provided with continuous diagonal bar plate in addition, by the connection each other of diagonal bar plate, constructs a plurality of stress points in inner chamber, thereby improves the rigidity intensity of integral section plate.
Adopt the inner panel and the outside plate of different arc angles and radius, help having the transition structure of higher load parameter in the formation of place, car body side roof part end angle.
For optimizing the rigidity intensity of diagonal bar plate and inner panel, outside plate connecting portion, can take following improvement project:
Described diagonal bar plate and inner panel or with the section bar thickness of the connecting portion of outside plate, greater than other positions of inner panel or outside plate.
For improving the spot welding switching performance after profile plate is pegged graft, after two adjacent profiles plates are pegged graft mutually, form a bevel for welding that is 60 °-80 ° between the inserted sheet.
As mentioned above, the utility model vehicle body of railway vehicle side roof part connection profile plate has the following advantages:
1, takes into account lightweight and the designing requirement of carrying rigidity on the whole, improve the Joint strenght between car body side roof part and the side wall effectively.
2, under high-speed travel state, can reduce the vibrations and the consequent noise of roof and side wall, thereby improve the ride quality of interior.
3, optimize the automatization level of car body assembly welding, reduced welding capacity and problem on deformation in the welding process.
4, can improve the load capacity at place, car body side roof part end angle, transition structure integral body can be born higher pressure.
