Description
Technical field
The utility model category car assembles engineering device technique field, and in particular to a kind of bus middle layer skeleton and side wall frame
Connection structure.
Background technique
With the development of present urbanization process, urban population is increasing, and urban public transport system is also gradually more
New to regenerate, double-decker bus is big relative to single layer public transport carrying capacity, and seat accounting high degree of comfort is high, has in urban public transport
Certain advantage.Bilayer bus is mostly the aluminium vehicle body of steel vehicle body or structural material surplus at present, and kerb weight is big, in existing electricity
Meet course continuation mileage under pool technology and charging time demand pressure is larger, therefore optimization reduction complete vehicle quality exists on body structure
There is important value in the popularization of new energy bilayer bus.
The connection type of existing car body of aluminum alloy bilayer bus middle layer skeleton and side wall mainly has direct welding and riveting
Or bolted-on connection, since all load in middle layer reach side wall by junction, the usual stress in junction is larger, if dealing with improperly
It is easy to appear situations such as stress concentrates failure or rigidity of the vehicle insufficient；Lead between usual middle layer framework beam and side wall frame column
The right angle flange with reinforcing rib is crossed to connect, this connection defect has: connector being needed to have biggish rigidity, generally steel connects
Part, quality weight；This connection to middle layer skeleton constraint be mainly connector horizontal plane hold middle layer framework beam lower plane with
The constraint for providing vertical direction prevents middle layer from dropping, and the rotational restraint that connector is supplied to middle layer framework beam is insufficient, needs to use
The middle layer framework beam of greater stiffness keeps middle layer floor indeformable, to vehicle loss of weight brings restriction.
Utility model content
The purpose of the utility model is to provide the connection structure of a kind of bus middle layer skeleton and side wall frame, reduce existing
There is the weight of double-decker bus connector.
The utility model the technical scheme adopted is that a kind of bus middle layer skeleton and side wall frame connection structure,
It includes middle layer framework beam, connector and side wall frame column, and one end of the connector is inserted into the framework beam of middle layer,
The other end of the connector is bonded fixation with side wall frame column.
The utility model is also characterized by
The connector includes Assembly rail, upper torque arm, support arm, web and bottom plate, and one end of the Assembly rail is in
Layer framework beam connection, the top of the other end connects with upper torque arm, and lower part is connected with support arm, the upper torque arm and support arm
End is connect with bottom plate, and the web is arranged in the cavity that upper torque arm, support arm and bottom plate surround.
The upper torque arm, support arm and bottom plate surround triangle.
Lightening hole is provided on the web.
The lightening hole is circle.
The connector is aluminum casting.
The middle layer framework beam is fixed by rivet interlacement with connector, connector and side wall frame column.
Compared with prior art, the utility model is by being inserted into the intracavitary assembly method of middle layer framework beam type for connector
Stronger constraint is provided for middle layer framework beam, the rigidity requirement of middle layer framework beam itself is reduced, is that middle layer skeleton is horizontal
The drop of beam provides condition again.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The utility model embodiment provides the connection structure of a kind of bus middle layer skeleton and side wall frame, such as Fig. 1-3 institute
Show comprising it includes middle layer framework beam 1, connector 2 and side wall frame column 3, in one end insertion of the connector 2
In layer framework beam 1, the other end of the connector 2 is bonded fixation with side wall frame column 3；
In this way, connector 2 be inserted into the intracavitary assembly method of 1 type of middle layer framework beam be middle layer framework beam 1 provide compared with
Strong constraint, reduces the rigidity requirement of middle layer framework beam 1 itself, provides condition again for the drop of middle layer framework beam 1.
The connector 2 includes Assembly rail 21, upper torque arm 22, support arm 23, web 24 and bottom plate 25, the assembly
One end of bar 21 and middle layer framework beam 1 connect, and the top of the other end and upper torque arm 22 connect, and lower part and support arm 23 connect,
The end of the upper torque arm 22 and support arm 23 is connect with bottom plate 25, and the web 24 is arranged in upper torque arm 22, support arm 23
And in the cavity that surrounds of bottom plate 25；The upper torque arm 22, support arm 23 and bottom plate 25 surround triangle；On the web 24
It is provided with circular lightening hole 241；The connector 2 is aluminum casting；
In this way, the connector 2 of cast aluminium have lighter own wt, with group weldering steel connector than high production efficiency,
Good product consistency.Four faces of Assembly rail 21 can conduct stress with the intracavitary face contact of type of middle layer framework beam 1；It is circular
Lightening hole 241 can be used for low-voltage line, tracheae, water pipe channel of support bottom plate 25 etc..
The middle layer framework beam 1 is connected and fixed by rivet 4 with connector 2, connector 2 with side wall frame column 3；
In this way, the connection rivet force way of Assembly rail 21 and middle layer framework beam 1 is shearing condition, preferably it is utilized
The stronger shear strength of rivet.The assembly method of Assembly rail 21 and middle layer framework beam 1 can be provided for middle layer framework beam 1 compared with
Strong rotational restraint makes the both ends of middle layer framework beam 1 be similar to clamped restrained condition, resists load to middle layer framework beam 1
The rigidity requirement of deformation reduces, and can reduce 1 profile section of middle layer framework beam to reduce weight.
Assembling process: the Assembly rail 21 of the connector 2 of cast aluminium is inserted into the type chamber of 1 aluminum profile of middle layer framework beam, with riveting
Nail 4 passes through 1 aluminum profile of middle layer framework beam and the preprocessing hole of cast aluminium bond-linkage element 2 rivets assembly.The bottom plate 25 of cast aluminium bond-linkage element 2
It is fixed with 3 inner face of side wall frame column patch merga pass rivet 4, complete assembly.
Compared with prior art, the connection structure of bus middle layer provided in this embodiment skeleton and side wall frame pass through by
The intracavitary assembly method of connector insertion middle layer framework beam type provides stronger constraint for middle layer framework beam, to middle layer bone
The rigidity requirement of frame crossbeam itself reduces, and provides condition again for the drop of middle layer framework beam.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
It is subject to the protection scope in claims.
