Technical field
The utility model relates to bus body manufacturing technology fields, particularly relate to a kind of hybrid bus body bone of steel/aluminium
The local connection structure of frame.
Background technique
The structure type of bus body skeleton plays vehicle performance very important effect.In general, body frame is about
Account for 1/3 or so of complete vehicle quality, about 70% fuel consumption is on body quality in vehicle traveling process, body frame light weight
Changing design is one of the key measure as automobile lightweight.
Aluminium alloy has the advantages that density is low, specific strength is high, is one of preferred material of automotive light weight technology, Study on Steel/aluminium
Hybrid combination vehicle body becomes a kind of trend of coach body structure light-weight design.
Steel/aluminium connection method mainly has the modes such as welding, mechanical connection, bonding, composite joint.The welding of steel/aluminium by
The limitation of assembly precision, welding equipment demand, the welding surroundings of workpiece etc., it is few using what is produced on a large scale, and welding efficiency
It is low.Steel/aluminium mechanical connection is mainly riveting technology and Stamping connection technique, stamping connection on body structure using basic office
It is limited to car door, hood, luggage warehouse lid, wheel cover equal strength and requires relatively low place, and application cost is high, use is not wide
It is general.Bonding connection poor heat resistance, glue-line are easy aging, and impact strength is low, and performance is unstable, deposit when applying in body structure
In security risk, and it is conductive, heating conduction is poor, complex procedures, and connection is limited by equipment size.The design provides one
Kind low cost, the local connection structure for facilitating the feasible hybrid bus body skeleton of steel/aluminium, using this part connection knot
Structure has achieved the purpose that body lightening, while effectively increasing, it can be achieved that low cost between steel/aluminum profile, facilitate feasible connection
Qiang Gang/aluminium one body frame integral strength.
Utility model content
The purpose of the utility model is to overcome welding difficulties between the hybrid bus body skeleton connection of existing steel/aluminium
Greatly, welding efficiency is low；Riveting, stamping connection intensity is not high；Bonding connection poor reliability, material destructible etc. are asked using limitation
Topic, proposes a kind of local connection structure of hybrid bus body skeleton of steel/aluminium.
To achieve the above object, the technical solution of the utility model is: a kind of hybrid bus body skeleton of steel/aluminium
Local connection structure, including vehicle body aluminium-alloy pipe 1, vehicle body steel pipe 2, connection steel disc 3 and connection bolt 4, with connection bolt 4
The connection steel disc 3 being welded on vehicle body steel pipe 2 is mechanically connected with vehicle body aluminium-alloy pipe 1, to realize bus body bone
The connection of frame steel/two kinds of different materials of aluminium.
The vehicle body aluminium-alloy pipe 1 is connected position and is provided with two the first circular through holes 5.
The two sides of 2 connecting portion of vehicle body steel pipe be welded with respectively connection steel disc 3,2 two sides of vehicle body steel pipe with connect steel disc 3
It is in T-shape connector after welding.
3 shapes of the connection steel disc are L-shaped and are provided with the second circular through hole 6.
The second circular through hole 6 on the connection steel disc 3 is connected first circular through hole at position with vehicle body aluminium-alloy pipe 1
5 installation sites connected for bolt 4.
Compared with prior art, the utility model has the beneficial effects that
This connection structure can realize low cost between steel/aluminum profile, facilitate feasible connection, reach bus body light weight
The purpose of change, while can effectively enhance steel/aluminium integration bus body skeleton integral strength, the utility model structure passes through
Vehicle body steel pipe is welded together with steel disc is connect, then vehicle body aluminium-alloy pipe and connection steel disc are bolted, realization steel/
Body frame between two kinds of profiles of aluminium locally connects, easy to operate, low in cost, convenient for promoting.
Detailed description of the invention
The axonometric drawing of Fig. 1 the utility model part connection structure.
Fig. 2 is vehicle body steel pipe and the axonometric drawing that connect steel disc.
Fig. 3 is the axonometric drawing that vehicle body aluminium-alloy pipe is connected position.
Specific embodiment
The utility model patent is described in further detail below in conjunction with Detailed description of the invention and specific embodiment.
Referring to Fig. 1, a kind of local connection structure of the hybrid bus body skeleton of steel/aluminium, including vehicle body aluminium-alloy pipe 1,
Vehicle body steel pipe 2, connection steel disc 3 and connection bolt 4.The vehicle body aluminium-alloy pipe 1 is square steel, is connected position at it and is provided with
First circular through hole 5,3 shape of connection steel disc is L-shaped and is provided with the second circular through hole 6, the vehicle body steel pipe 2
For square steel, be welded with connection steel disc 3 respectively in the two sides of its connecting portion, vehicle body steel pipe 2 with connect composition " T " after the welding of steel disc 3
The connector of type will connect steel disc 3 finally by connection bolt 4 and vehicle body aluminium-alloy pipe 1 links together, and then realization steel/
Body frame between two kinds of profiles of aluminium locally connects.
The first circular through hole 5 that the vehicle body aluminium-alloy pipe 1 is connected on position and the second circle connecting on steel disc 3 are logical
By drilling, the connection steel disc 3 is made of sheet metal process in hole 6.
The second circular through hole 6 on the connection steel disc 3 is connected first circular through hole at position with vehicle body aluminium-alloy pipe 1
The second circular through hole 6 connected on steel disc 3 is connected position with vehicle body aluminium-alloy pipe 1 by 5 installation sites connected for bolt 4
