Abstract
The invention relates to the field of frame structure, more particularly to a splitting frame longitudinal beam. The splitting frame longitudinal beam comprises a longitudinal beam outer board and a longitudinal beam inner board, wherein the longitudinal beam outer board is split, in the length direction, into at least two sections, which are connected with each other tightly and fixedly. The sectional structure design of the frame longitudinal beam can control twisting deformation and resilience of the longitudinal beam by means of punching process after the optimization for the length of the sections of the longitudinal beam, so the product quality is high. The welding debugging for the assembly of the longitudinal beam outer and inner boards and the assembly of the frame body is convenient, the dimensional adjustment for the frame is flexible, the deformation can be corrected, and the robot can be used without risk. The sectional longitudinal beam has strong adaptability to future wheelbase-changeable vehicles, the model switching flexibility is strong, the length of the longitudinal beam can be changed only by adjusting the positioning of the middle section of the longitudinal beam, the labor intensity of working staff is low, the operating efficiency of working staff is high, the investment cost of moulds is low, no large press is required, continuous production can be realized and the operating efficiency is high.
Description
Technical field
The present invention relates to the body frame structure for automotive field, specifically, relate to a kind of split type chassis side rail.
Background technology
Chassis side rail integral design structure, longeron length is near 5m.Because longeron length is long and complex-shaped, the internal stress that is shaped so will be very big, and the longeron torsional deflection is big, the portraitlandscape resilience is big, the process control difficulty thereby cause.
At first, longeron is the reference for assembling spare of vehicle frame, if product design can not get guaranteeing, there are big difficulty in inside and outside plate assembly weldering of longeron and vehicle frame body welding debugging, the vehicle frame size adjusting is dumb, and there are risk in no arbour press meeting, the particularly application to robot.
Secondly, the vehicle bad adaptability that the integral type girder work changes for following wheelbase relies on die cuts to bring the very flexible that changes longeron length, the workman switch mould labour intensity big, use duration, employee's operating efficiency is low.
It, uses equipment tonnage big at large mold cost of investment height again, needs the above press of 4000T, is subjected to the large equipment quantity limitation, can only single preface production, and operating efficiency is low.So it is very outstanding to design sectional type girder work advantage.
Summary of the invention
The present invention is directed to problems of the prior art, a kind of split type chassis side rail is provided.
In order to realize purpose of the present invention, the technical solution used in the present invention is:
A kind of split type chassis side rail comprises longeron outside plate and longeron inner panel, and described longeron outside plate is divided at least two sections on length, is fastenedly connected between described at least two sections longeron outside plates.
Described longeron outside plate is divided into longeron outside plate leading portion, longeron outside plate stage casing, longeron outside plate back segment successively on length.
Described longeron inner panel is divided at least two sections on length, be fastenedly connected between described at least two sections longeron inner panels.
Described longeron inner panel is divided into longeron inner panel leading portion, longeron inner panel stage casing, longeron inner panel back segment successively on length.
Beneficial effect of the present invention is:
1, chassis side rail segmented body formula project organization after each segment length optimization of longeron, can pass through the Sheet Metal Forming Technology means, makes longeron torsional deflection and resilience controlled, the product design height.
2, convenient for inside and outside plate assembly welding of longeron and vehicle frame body welding debugging, the vehicle frame size adjusting is flexible, and distortion has the arbour press meeting, to the application devoid of risk of robot.
3, the sectional type girder work is strong for the vehicle comformability that following wheelbase changes, and it is strong that mould switches alerting ability, only needs to adjust location, longeron stage casing and just can change longeron length, and it is low that the workman operates labor intensity, employee's operating efficiency height.The mould cost of investment is low, does not need to use large press, but line production, the operating efficiency height.
