Abstract
The utility model relates to the field of frame structures, in particular to a split type frame longitudinal beam, which comprises a longitudinal beam outer plate and a longitudinal beam inner plate, wherein the longitudinal beam outer plate is divided into at least two segments in the length, and the at least two segments of longitudinal beam outer plates are tightly connected. According to a split type frame longitudinal beam structure, after the length of each segment of longitudinal beam is optimized, through a sheet metal forming technology, the distortion and the springback of the longitudinal beam can be controlled, and the product quality is high. Debugging for the welding of the longitudinal beam outer plate and the longitudinal beam inner plate as well as the welding of the frame is convenient, the size of the frame can be flexibly adjusted, the distortion can be corrected, and the application of a robot is risk-free. The split type longitudinal beam has strong adaptability for future motorcycle types with wheel base change, and strong flexibility for mould switching, the length of the longitudinal beam can be changed by adjusting the location of the middle segment of the longitudinal beam, the labor intensity of workers is low, the working performance of the workers is high, the investment cost of a mold is low, a large-size pressing machine is not needed, in-line production can be carried out, and the working performance is high.
Description
Technical field
The utility model relates to the body frame structure for automotive field, specifically, relates 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.
The utility model content
The utility model provides a kind of split type chassis side rail at problems of the prior art.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model 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.
The beneficial effects of the utility model are:
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.

Fig. 1 is one of the utility model structural representation.
Fig. 2 is two of a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Embodiment 1: referring to Fig. 1.
A kind of split type chassis side rail comprises longeron outside plate 1 and longeron inner panel 2, and described longeron outside plate 1 is divided into two sections on length, is fastenedly connected between two sections longeron outside plates.
Described longeron inner panel 2 is divided into two sections on length, be fastenedly connected between two sections longeron inner panels.
Adopt the mode of welding that two sections longeron outside plates and two sections longeron inner panels are tightened together in the present embodiment.
Embodiment 2: referring to Fig. 2.
A kind of split type chassis side rail, comprise longeron outside plate 1 and longeron inner panel 2, described longeron outside plate 1 is divided into longeron outside plate leading portion 3, longeron outside plate stage casing 4, longeron outside plate back segment 5 successively on length, described longeron inner panel 2 is divided into longeron inner panel leading portion 6, longeron inner panel stage casing 7, longeron inner panel back segment 8 successively on length.
Fastening means includes but not limited to welding manner.
The utility model is not limited to the above specific embodiment, and the split type chassis side rail that every structure is identical with the utility model, and the simple substitute of known configurations all drop within the protection domain of the present utility model.
