Description
Technical Field
The invention relates to the field of automobile frames, in particular to a frame and an automobile.
Background
The development scheme of the trapezoid frame in the existing industry is to design a structural scheme of the frame according to a performance target defined by the whole vehicle, the pertinence is high, each vehicle type has an independent frame technical scheme, each support of a front suspension module is independently welded on a longitudinal beam assembly, each support of a rear suspension module is respectively welded on a longitudinal beam and a cross beam, a transmission support beam is welded with the longitudinal beam, and the longitudinal beam is formed by splicing front and rear sections of reinforcing plates. Each system and each part are provided with an independent stamping die and a welding tool, and all the parts are not integrated into a module unit. In the manufacturing process, because parts cannot be borrowed, equipment such as special stamping dies, welding tools, inspection tools and the like are too much, development cost is increased, development period is increased, and more human resources are input. This development model is also disadvantageous for the management of the chassis and the platform expansion. The current scheme of the frame can not realize the change of wheel track, wheel base and performance through the lap joint change of parts of the frame, so as to adapt to the use of different vehicle types of the same platform.
Referring to fig. 1, the following problems occur when the wheelbase or tread of the frame is increased on the basis of the frame of fig. 1:
1. the manufactured frame can not meet the reliability requirement of road test, and the problems of cracking, open welding and the like easily occur in the road test process;
2. when load is applied to the manufactured frame, the maximum pressure is greater than the allowable yield strength of the frame material, so that the frame can be cracked and welded in road tests and experiments, and the requirement that the maximum stress is less than 1% is not met;
3. the types of the cross beams of the existing frame are 8 (comprising a cross beam B, a cross beam C, a cross beam D, a cross beam E, a cross beam F, a cross beam G, a cross beam H and a cross beam I), when the cross beam is produced, because the structures of the 8 cross beams are different, when the length of the cross beam is increased, 8 sets of dies are required to be adjusted simultaneously, so that the production cost is greatly increased;
4. the cross section sizes of a longitudinal beam A and a cross beam (B, C, D, E, F, G, H, I) of the prior art are narrow, and the requirements of the lengthened and widened vehicle frame on the performance of the whole vehicle cannot be met;
5. the longitudinal beam of the original frame is formed by overlapping 4 plates at different positions, and if the wheel base is to be increased by changing the length of parts, at least four sets of dies for adjusting the rear plate of the left longitudinal beam and four sets of dies for adjusting the rear plate of the right longitudinal beam are needed.
Moreover, due to the limitation of the existing frame platform, one frame platform cannot simultaneously produce 8 cross beams with different structures.
The conditions are combined, so that the wheel base or wheel track of the existing frame structure cannot be changed to produce frames of different types meeting the performance requirements, and multiple frames of the same structure and different types cannot be produced through one frame platform.

Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments. In the following description, specific details such as specific configurations and components are provided merely to facilitate a thorough understanding of embodiments of the invention. It will therefore be apparent to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.
Referring to fig. 2 to 9, a vehicle frame according to an embodiment of the present invention includes:
a first longitudinal beam 1 and a second longitudinal beam 2 which are arranged oppositely;
a first cross beam 3, a second cross beam 4, a third cross beam 5 and a fourth cross beam 6 which are fixed between the first longitudinal beam 1 and are arranged in parallel with each other, and the fourth cross beam 6 is arranged at the middle position of the first longitudinal beam 1 and the second longitudinal beam 2;
wherein the first stringer 1 and the second stringer 2 each comprise:
a first side member 101;
a second side rail 102 connected to the first side rail 101, and grooves penetrating through two opposite end surfaces of the second side rail 102 are formed in the second side rail 102;
and a third side member 103 connected to an end of the second side member 102 remote from the first side member 101.
In the embodiment of the invention, the number of the cross beams is reduced from 8 to 4, and when the frame is produced, only the dies of the four cross beams are required to be changed, so that the manufacturing cost is reduced, and meanwhile, the frame can be produced in various types through a frame platform.
Specifically, in the embodiment of the present invention, the first cross beam 3, the third cross beam 5 and the fourth cross beam 6 are two groups, the two groups of first cross beams 3 are respectively disposed at two ends of the first longitudinal beam 1 and the second longitudinal beam 2, the second cross beam 4 is one group, and the second cross beam 4 is located between one group of first cross beams 3 and the third cross beam 5.
The first longitudinal beam 1 and the second longitudinal beam 2 are made of plates with the thickness of 6mm, and particularly the plates with the model B510L are adopted. The yield strength of the B510L-type plate is 355Mpa, which is stronger than the material yield strength of the original frame. The first side member 101 and the third side member 103 have a height of 350mm, the second side member 102 has a height of 310mm, the first side member 101 and the third side member 103 have a length of 106mm on the side parallel to the plurality of cross members, and the second side member 102 has a length of 124mm on the side parallel to the plurality of cross members.
In the embodiment of the present invention, the second side member 102 is linear, and the purpose of arranging the second side member 102 in a linear shape is to facilitate the adjustment of the length of the side member of the vehicle frame, and the adjustment of the length of the side member is achieved by adjusting the length of the second side member 102. In the case that the lengths of the first side member 101 and the third side member 103 are unchanged, the requirement of adjusting the model of the frame from a short wheelbase model to a long wheelbase model size can be met by lengthening the length of the second side member 102.
Because the cross-sectional dimensions of the first side member 101, the second side member 102 and the third side member 103 in the embodiment of the present invention are all larger than those of the original side members, when the frame is in a bending working condition and the front and rear axles are impacted simultaneously, the side members provide sufficient deformation resistance and meet the mechanical properties required by the frame platform.
Through optimizing the structure of the longitudinal beam, the thickness of the longitudinal beam manufacturing material is increased (from original 3mm to 6 mm), the manufacturing material is changed, and the section size of the longitudinal beam is increased, so that the performance requirements of the platform on frames of three different types with the same frame structure are met.
In the embodiment of the invention, the frame structure can be used for manufacturing three types of frames, and comprises the following components: the vehicle frame comprises a standard wheelbase vehicle frame, a long wheelbase vehicle frame and a wide wheel base vehicle frame, wherein the wheelbase of the long wheelbase vehicle frame is larger than that of the standard wheelbase vehicle frame, the wheel base of the wide wheel base vehicle frame is larger than that of the standard wheelbase vehicle frame, the three types of vehicle frames are manufactured through one vehicle frame platform, and the performance requirements of the three types of vehicle frames are firstly counted when the vehicle frame platform is used for production due to different vehicle frame performance requirements of the different types of vehicle frames, and the vehicle frames of the three types of vehicle frames are produced with the highest performance requirements as targets, so that the produced vehicle frames of the different types of vehicle frames can meet the requirements.

Two sets of first cross members 3 are provided at both end positions of the first side member 1 and the second side member 2, respectively. Referring to fig. 2, it can be seen that the first beam 3 is connected with the first longitudinal beam 1 and the second longitudinal beam 2 through the front protection beam patch 32 and the front board beam rear board, and when the wide wheel track frame needs to be produced, the welding positions of the front protection beam patch 32 and the front protection beam rear board 33 can be adjusted by increasing the length of the first beam body 31. The reason why the length of the first beam body 31 can be directly increased is that the structure of the first beam body 31 is not changed.
In the embodiment of the present invention, the length of the first cross member 3 in the direction parallel to the first cross member 3 of the first longitudinal member 1 is a second preset value.
Here, the second preset value is 159mm, the height of the first cross beam 3 is 229mm, and in the embodiment of the present invention, the first cross beam 3 is made of a B510L type profile with a thickness of 6mm, and the yield strength of the first cross beam 3 made of the type profile is greater than the yield strength of the cross beam of the original frame. The cross section size of the first cross beam 3 provided by the embodiment of the invention is larger than that of the original cross beam, when the frame is impacted, the torsion deformation resistance capability provided by the first cross beam 3 is enhanced, and the first cross beam 3 in the embodiment of the invention can meet the mechanical performance requirements of all frames of the platform.
