Description
Technical field
The utility model relates to bus body manufacturing technology fields, particularly relate to a kind of steel/aluminium vehicle body of light-weighted passenger vehicle bone
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
Lightweight structure 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 assembly precision of workpiece, welding equipment demand, welding surroundings/etc. limitation, it is a wide range of to use the few of production.Steel/aluminium is mechanical
Connection is mainly riveting technology and Stamping connection technique, and application of the stamping connection on body structure is essentially confined to car door, hair
Motivation cover, luggage warehouse lid, wheel cover equal strength require relatively low place, and application cost is high, and use is not extensive.Bonding connection
Poor heat resistance, glue-line are easy aging, and impact strength is low, and performance is unstable, and it is hidden that there is safety when applying in body structure
Suffer from, and it is conductive, heating conduction is poor, complex procedures, connection is limited by equipment size.The design provide it is a kind of low cost,
Facilitate the local connection structure of feasible steel/aluminium vehicle body of light-weighted passenger vehicle skeleton, using this local connection structure, it can be achieved that
Low cost between steel/aluminum profile facilitates feasible connection, has achieved the purpose that body lightening, while effectively enhancing steel/aluminium one
The integral strength of body body frame.
Utility model content
The purpose of the utility model is to overcome welding difficulties between existing steel/aluminium vehicle body of light-weighted passenger vehicle skeleton connection
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 steel/aluminium vehicle body of light-weighted passenger vehicle skeleton.
To achieve the above object, the technical solution of the utility model is: a kind of steel/aluminium vehicle body of light-weighted passenger vehicle skeleton
Local connection structure, including vehicle body aluminium-alloy pipe 1, vehicle body steel pipe 2, clutch collar 3 and connection bolt 4, with connection bolt 4 will weld
The clutch collar 3 connect on vehicle body steel pipe 2 is mechanically connected with vehicle body aluminium-alloy pipe 1, to realize bus body skeleton steel/aluminium
The connection of two kinds of different materials.
The vehicle body aluminium-alloy pipe 1 is connected position and is provided with the first circular through hole 5.
2 connecting portion of vehicle body steel pipe is welded with clutch collar 3, is in " fork " type connector after welding.
The clutch collar 3 is in " bow " type, and is provided with the second circular through hole 6.
The second circular through hole 6 on the clutch collar 3 is connected first circular through hole 5 at position with vehicle body aluminium-alloy pipe 1
The installation site 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 clutch collar, then vehicle body aluminium-alloy pipe and clutch collar are bolted, realizes steel/aluminium two
Body frame between kind profile 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 the axonometric drawing of vehicle body steel pipe and clutch collar.
Fig. 3 is the axonometric drawing that vehicle body aluminium-alloy pipe is connected position.
Fig. 4 is the axonometric drawing of clutch collar.
Appended drawing reference 5 and 6 is respectively the first circular through hole and the second circular through hole.
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 steel/aluminium vehicle body of light-weighted passenger vehicle skeleton, including vehicle body aluminium-alloy pipe 1,
Vehicle body steel pipe 2, clutch collar 3 and connection bolt 4.The vehicle body aluminium-alloy pipe 1 is square steel, is connected position at it and is provided with the
One circular through hole 5, the clutch collar 3 are provided with the second circular through hole 6, and the vehicle body steel pipe 2 is square steel, in its connecting portion
It is welded with clutch collar 3, first welds vehicle body steel pipe 2 and clutch collar 3, it is secondly that vehicle body aluminium-alloy pipe 1 is nested after welding
Clutch collar 3 in, later by connect bolt 4 clutch collar 3 and vehicle body aluminium-alloy pipe 1 are linked together, and then realize steel/aluminium
Body frame between two kinds of profiles locally connects.
The vehicle body aluminium-alloy pipe 1 is connected the first circular through hole 5 on position and the second circular through hole on clutch collar 3
6 by drilling, and the clutch collar 3 is made of sheet metal process.
The second circular through hole 6 on the clutch collar 3 is connected first circular through hole 5 at position with vehicle body aluminium-alloy pipe 1
The installation site connected for bolt 4.
The utility model structure by bolted connection, realizes the office of the body frame between two kinds of profiles of steel/aluminium
Portion's connection, can be improved the intensity of vehicle body part connecting portion, easy to operate, low in cost, convenient for promoting.
