A kind of full aluminium chassis frame
The utility model is related to technical field of vehicle, more specifically a kind of full aluminium chassis frame.
Two longeron of vehicle frame is generally mutually parallel at present, and longeron is generally crossed using I-steel or two section bar part of channel steel
Welding is completed, and welding is so that the production cost increases, easy stress concentration and deformation after welding, cause in later stage use weld cracking or
Beam deforms, while the installation requirement to meet driver's cabin, and the forepart horizontal distance of two longerons is smaller, and rear portion installation suspension part
Horizontal distance is larger between two longerons needed for being divided to, therefore at the crossbeam both ends at vehicle frame rear portion beyond longeron, but with economic society
Development, the use scope of lorry is more and more wider, the heavily loaded cargo that some are small, density is big is particularly transported, because of vehicle
Frame longeron forepart is to be welded to connect, and suspension is mounted in frame cross with rear portion, and load-bearing capacity is subject to certain restrictions.If vehicle
Frame longeron forepart and rear design pass through transverse fold and make rear portion distance increase between two longeron of vehicle frame into an entirety,
Suspension is mounted on longitudinal beam.Steel or aluminium section structure now in the market can not meet longitudinal beam requirement.Such as
What provides a kind of low early and high after and energy transverse curvature frame carling structure to form vehicle frame light-weight, that intensity is high as ability
The problem of field technique personnel institute facing.
The goal of the invention of the utility model is for shortcoming of the prior art, provides a kind of light-weight, intensity
Height can meet the low early and high after and energy full aluminium chassis frame of transverse fold.
The utility model is achieved through the following technical solutions：
A kind of full aluminium chassis frame includes several crossbeams of two longerons of symmetrically arranged two longerons and connection, described
Longeron includes integrally formed forepart longeron, bending part and rear portion longeron, and the bending part connects the forepart longeron and described
The distance between rear portion longeron, the forepart longeron of two longerons be less than between the rear portion longeron of two longerons away from
From；The bending part includes upper flange, middle wing plate and lower wing plate, and the upper flange is connect with middle wing plate by epiplastron, described
Middle wing plate is connect with lower wing plate by bottom web；The top surface of the forepart longeron is not higher than the bottom surface of the rear portion longeron.
Optimizing, above-mentioned crossbeam includes preceding interior crossbeam, rear interior crossbeam, and interior crossbeam is arranged between the longeron of forepart before described,
Crossbeam is arranged between the longeron of rear portion in after described.
Optimization, interior crossbeam is arranged on the rear end of forepart longeron before above-mentioned.
Further, above-mentioned rear interior crossbeam includes rear interior crossbeam I and interior crossbeam II afterwards, after interior crossbeam I is arranged on after described
The front end of portion's longeron, interior crossbeam II is arranged on the rear end of rear portion longeron after described.
Above-mentioned crossbeam is equipped with strengthening web with longeron junction.
The R of above-mentioned bending part is 1985mm.
Above-mentioned forepart longeron front end is equipped with front bezel, and the rear portion longeron rear end is equipped with rear frame.
Above-mentioned longeron, crossbeam, front bezel, rear frame and strengthening web are light-weight using almag material.
The beneficial effects of the utility model are：The utility model bending part includes upper flange, middle wing plate and lower wing plate, described
Upper flange is connect with middle wing plate by epiplastron, and the middle wing plate is connect with lower wing plate by bottom web, is similar to bis- " works "
Word structure, longeron are integrally formed, and front end upper flange, epiplastron remove, and rear end lower wing plate, bottom web remove, overall construction intensity
Height, the body frame structure for automotive is beloid, meets the requirement that suspension is installed on vehicle frame left-right longeron.
