Preferably, described first longeron and described second longeron are symmetrical arranged.
Preferably, the two ends of described crossbeam and described jack are welded and fixed.
Preferably, described automobile is truck.
Further, described many crossbeams comprise along described first longeron and described second longeron length direction successively spaced change-speed box crossbeam for supporting change-speed box, for the transmission shaft crossbeam of supporting shaft, for supporting the front side fuel tank crossbeam of fuel tank and the rear side fuel tank crossbeam for supporting fuel tank.
Further, described many crossbeams also comprise the spare tyre lifter crossbeam for supporting spare tyre lifter, and described spare tyre lifter crossbeam is positioned at the side of described rear side fuel tank crossbeam away from described front side fuel tank crossbeam.
Preferably, described jack is circular hole, and described many crossbeams are circular tube shaped.
Compared with prior art, the beneficial effects of the utility model are:
1, crossbeam and longeron are split type, and it manufactures respectively, and are fixed on longeron by crossbeam, and manufacturing process is simple, and cost is low;
2, welding manner is adopted to be connected crossbeam and longeron, the Joint strenght of both guarantees;
3, crossbeam selects circular tube shaped, and its commonality is high, is convenient to processing.

Description of reference numerals
1-first longeron; 2-second longeron; 3-change-speed box crossbeam; 4-transmission shaft crossbeam; Fuel tank crossbeam on front side of 5-; Fuel tank crossbeam on rear side of 6-; 7-spare tyre lifter crossbeam; 8-circular hole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
The utility model relates to the vehicle frame of automobile, and it such as, for supporting the various functions parts on automobile, fuel tank, transmission shaft etc.
See Fig. 1 ~ Fig. 3, the utility model discloses a kind of automobile chassis frame, it comprises the first longeron 1, second longeron 2 and many crossbeams between the first longeron 1 and the second longeron 2.First longeron 1 and the second longeron 2 are configured to outer rim, and many crossbeams are positioned at this outer rim.
For ease of manufacturing, the first longeron 1 offers several relative jacks along its length with the second longeron 2, and the two ends of each crossbeam are inserted in jack also fixing.This jack can be through hole, or is blind hole.When assembling vehicle frame, crossbeam being inserted in jack, and being fixed.This fixed form, can be chosen as threaded connector and fix or other usual manners, and for improving the intensity connected, in the utility model, two ends and the jack of crossbeam adopt the mode of welding to fix.
For ease of the carrying of balanced vehicle frame, in the utility model, the first longeron 1 and the second longeron 2 are symmetrical arranged.Namely as shown in Figure 1, the two is symmetrical relative to the line of centers in figure, is provided with multiple jack in the side of the side of the first longeron 1 and the second longeron 2.As optimal way, in the utility model, jack is chosen as the circular hole 8 shown in Fig. 3, and it is easy to process.Accordingly, each crossbeam is all chosen as circular tube shaped, this crossbeam, highly versatile, is convenient to select.Meanwhile, adopt circular hole 8 and circular tube shaped crossbeam, its assembling is also more convenient.
Automobile chassis frame in the utility model, can be applied to many dissimilar automobiles, and as a kind of mode, this automobile is truck.
For automobile, different choice can be made in the installation site of fuel tank, needs according to design and use and is arranged on the diverse location of the length direction of vehicle frame.
Aforesaid many crossbeams comprise along the first longeron 1 and the second longeron 2 length direction (specifically, by the head end of automobile chassis frame to tail end direction) spaced change-speed box crossbeam 3, transmission shaft crossbeam 4, front side fuel tank crossbeam 5 and rear side fuel tank crossbeam 6 successively, the spacing between these crossbeams can be determined according to concrete vehicle.Wherein, change-speed box crossbeam 3, for supporting change-speed box; Transmission shaft crossbeam 4, for supporting shaft; Front side fuel tank crossbeam 5, for supporting fuel tank; Rear side fuel tank crossbeam 6 is also for supporting fuel tank.At the beginning of this Vehicle Frame Design, just front side fuel tank crossbeam 5 and rear side fuel tank crossbeam 6 are all designed, when car assembling, the rigging position of fuel tank can be selected between.In addition, for truck, some trucies are configured with two fuel tank, and front side fuel tank crossbeam 5 also can be utilized to support this two fuel tanks respectively with rear side fuel tank crossbeam 6.
Further, for truck class automobile, its chassis is higher, and usually overhead position is higher for its spare tyre, and weight is comparatively large, therefore, need adopt spare tyre lifter to handle spare tyre lifting to change.For this situation, in the utility model, many crossbeams also comprise the spare tyre lifter crossbeam 7 for supporting spare tyre lifter, and spare tyre lifter crossbeam 7 is positioned at the side of rear side fuel tank crossbeam 6 away from front side fuel tank crossbeam 5.Continue as shown in fig. 1, this spare tyre lifter crossbeam 7 is positioned at the tail end of this automobile chassis frame.
This automobile chassis frame of the present utility model, its mode adopting crossbeam and longeron grafting also to fix, the operation eliminating punching press and weld on a large scale, therefore, its manufacture is more simple, and productive costs is more cheap.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can in essence of the present utility model and protection domain, and make various amendment or equivalent replacement to the utility model, this amendment or equivalent replacement also should be considered as dropping in protection domain of the present utility model.
