Description

A kind of lightweight total-bearing formula passenger car body skeleton structure

Technical field

The present invention relates to automobile manufacturing field, specifically, relate to a kind of full-bearing type bus body frame structure that adopts aluminum alloy materials to manufacture.

Background technology

The passenger car body skeleton by underframe, all around skeleton and roof skeleton six large stretch of skeletons constitute, and according to the difference of vehicle body bearing load degree, can be divided into non-bearing formula, half bearing-type and three kinds of body frame structures of full-bearing type.Wherein, the non-bearing formula is meant that automobile has chassis frame, and vehicle body places on the chassis frame, connects with elastic element, mainly leans on the chassis frame load-bearing, and vehicle body is not participated in stressed.Half bearing-type; Be meant that auto body underframe and chassis frame are integrated, the bracket through on chassis frame, being provided with, vehicle body chassis member such as beam in length and breadth make chassis frame be connected with body understructure; And then with other five large stretch of connections of vehicle body, constitute the vehicle body hexahedron jointly.The common load-bearing of body understructure and chassis frame.Full-bearing type is meant that automobile does not have chassis frame, and vehicle chassis component like driving engine, front and back bridge etc., directly is contained on the body understructure, and vehicle body six big chip architectures are leaned in load-bearing fully.

In the reality, utilize aluminum alloy materials to replace steel to use as the body framing material is existing, than the steel passenger vehicle, the advantage of aluminium passenger vehicle is; Car body weight reduces, and load-carrying capacity is improved, and energy consumption is minimized, and; Aluminium is difficult for by corrosion, so body framing is able to prolong service life.The change of material is an aspect of passenger vehicle lightweight research, is on the other hand, when material changes, how to guarantee that passenger vehicle intensity is constant, even improves, and this is then relevant with passenger car body skeleton structure and connection mode design thereof.As previously mentioned, body frame structure is divided into three kinds, in the reality; Existing full aluminium half bearing-type passenger vehicle technology is open; Disclose a kind of electronlmobil that adopts the full-bearing type aluminium alloy bicycle frame like CN201020283977, its vehicle frame is made up of underframe, side wall frame and roof skeleton, but this car still contains the chassis; Vehicle frame just part carries, so be merely half bearing-type passenger vehicle.Passenger car body skeleton connection mode has three kinds, promptly is spirally connected, rivets and weld.In the reality; The full aluminium full-bearing type passenger vehicle technology that existing employing was spirally connected, riveted mode discloses; Disclose a kind of lightweight coach body structure and section bar thereof like CN201010146534, its body framing comprises all around skeleton, roof skeleton and chassis truss, and connection mode adopts riveted joint.But dual mode before the welding under the identical situation of body frame structure, has the lower advantage of complete vehicle weight that makes.

Summary of the invention

The object of the invention just provides a kind of lightweight total-bearing formula passenger car body skeleton structure, and this body framing adopts aluminum alloy materials, through being welded to connect; Than the steel passenger vehicle, when having guaranteed car load intensity, reduced car body weight; Load-carrying capacity is improved, and the passenger vehicle energy consumption is minimized, and; Because aluminium is difficult for by corrosion, so, also obtain the service life of this body framing prolonging.
