And muscle plate can play the strength of joint between deep beam body and end further. Circular hole II can make cross-beam body reduce when reversing in the middle of the torsional stiffness at position, and then torsional deformation amount in position, intermediate portion is strengthened, prevents that the distortion of cross-beam body two ends is excessive to be caused and situation about ftractureing occurs in end plate weld. And the stress that the circular hole III that cross-beam body two ends are arranged produces when can make torsional deformation is released, it is to increase the reliability used. Cross-beam body is provided with to recessed groove, therefore can effectively increase the space between bottom transmission shaft and wheel box, prevent to interfere.
Description
Technical field
The present invention relates to heavy-duty car technical field, it is specifically related to a kind of shoulder pole formula frame cross structure.
Background technology
Elastic element many employings plate spring in the front suspension system of existing heavy-duty car, leaf spring front end is generally directly fixedly connected with front plate spring seat, and rear end is connected with rear spring block by hanger, and hanger can swing around spring block. Generally at forward and backward spring block place, a crossbeam is respectively installed, with the torsional stiffness of the intensity and vehicle frame that improve spring block. Because certain h type engine h location of entirely driving is lower, when transmission shaft between transfer gear and front driving axle skips to limit position bottom transmission shaft and wheel box between space owe well-to-do, cause crossbeam layout design difficulty herein, and the torsional stiffness of frame cross cannot be ensured.
Summary of the invention
The present invention is in order to overcome the deficiency of above technology, it provides a kind of can not interfere with wheel box and the strong shoulder pole formula frame cross structure of torsional stiffness.
The present invention overcomes the technical scheme that its technical problem adopts:
This shoulder pole formula frame cross structure, comprise the cross-beam body that cross section is U shape, it is fixedly welded on the end plate at two ends, cross-beam body left and right respectively, the some open holess being arranged on end plate and four L-shaped muscle plates, in the middle of the baseplane of cross-beam body, position is provided with some circular holes II, its two ends place, left and right, baseplane is respectively arranged with circular hole III, two lower ends of muscle plate are fixedly welded in cross-beam body left end two inner side plane, its outboard end is fixedly welded on the end plate in left side, another two lower ends of muscle plate are fixedly welded in cross-beam body 1 right-hand member two inner side plane, its outboard end is fixedly welded on the end plate on right side, two end plates utilizes threaded fastener to be fixed on two spring blocks installed at two ends, longitudinal beam left and right by open holes respectively, described cross-beam body is provided with to recessed groove.
In order to improve torsional stiffness, also comprising the note plate in X shape, four corners place of note plate is provided with plug welding hole II, and note plate is fixedly welded on the upper end open place of the groove location of cross-beam body by plug welding hole II.
In order to improve firm welding degree, the above-mentioned lower end of muscle plate is respectively arranged with some plug welding holes I.
In order to prevent weld from ftractureing, the middle position of above-mentioned note plate is provided with circular hole I.
The invention has the beneficial effects as follows: the cross-beam body of U shape possesses good anti-twisting property, it is to increase reliability, and weight gently reduces manufacturing cost. And muscle plate can play the strength of joint between deep beam body and end further. Circular hole II can make cross-beam body reduce when reversing in the middle of the torsional stiffness at position, and then torsional deformation amount in position, intermediate portion is strengthened, prevents that the distortion of cross-beam body two ends is excessive to be caused and situation about ftractureing occurs in end plate weld. And the stress that the circular hole III that cross-beam body two ends are arranged produces when can make torsional deformation is released, it is to increase the reliability used. Cross-beam body is provided with to recessed groove, therefore can effectively increase the space between bottom transmission shaft and wheel box, prevent to interfere.

Embodiment
Below in conjunction with accompanying drawing 1 to accompanying drawing 4, the present invention will be further described.
As shown in Figures 1 and 2, this shoulder pole formula frame cross structure, comprise the cross-beam body 1 that cross section is U shape, it is fixedly welded on the end plate 2 at cross-beam body about 1 two ends respectively, the some open holess 6 being arranged on end plate 2 and four L-shaped muscle plates 4, in the middle of the baseplane of cross-beam body 1, position is provided with some circular holes II 9, its two ends place, left and right, baseplane is respectively arranged with circular hole III 10, two muscle plates, 4 times ends are fixedly welded in cross-beam body 1 left end two inner side plane, its outboard end is fixedly welded on the end plate 2 in left side, another two muscle plates, 4 times ends are fixedly welded in cross-beam body 1 right-hand member two inner side plane, its outboard end is fixedly welded on the end plate 2 on right side. as shown in Figure 4, two end plates 2 utilizes threaded fastener to be fixed on two spring blocks 12 installed at longitudinal beam about 11 two ends by open holes 6 respectively, the cross-beam body 1 of U shape possesses good anti-twisting property, it is to increase reliability, and weight gently reduces manufacturing cost. and muscle plate 4 can play the strength of joint between deep beam body 1 and end 2 further. circular hole II 9 can make cross-beam body 1 reduce when reversing in the middle of the torsional stiffness at position, and then torsional deformation amount in position, intermediate portion is strengthened, prevents that the distortion of cross-beam body 1 two ends is excessive to be caused and situation about ftractureing occurs in end plate 2 weld. and the stress that the circular hole III 10 that cross-beam body 1 two ends are arranged produces when can make torsional deformation is released, it is to increase the reliability used. cross-beam body is provided with to recessed groove, therefore can effectively increase the space between bottom transmission shaft and wheel box, prevent to interfere.
As shown in Figure 3, also comprising the note plate 3 in X shape, four corners place of note plate 3 is provided with plug welding hole II 7, and note plate 3 is fixedly welded on the upper end open place of the groove location of cross-beam body 1 by plug welding hole II 7. By the note plate 3 of fixing X shape, cross-beam body 1 can be formed respectively structure, it is to increase its rigidity of antitorque turn. And note plate 3 is welded on cross-beam body 1 by the plug welding hole II 7 at four corners place to improve welding bead length, it is to increase welding strength. Ensure that the reliability of use.
As shown in Figure 1, muscle plate 4 times ends can be respectively arranged with some plug welding holes I 5. By plug welding hole I 5, the inner side plane of muscle plate 4 with cross-beam body 1 is welded, it is possible to improve welding bead length, it is to increase welding strength, thereby, it is ensured that the quality of welding.
As shown in Figure 3, the middle position of note plate 3 can be provided with circular hole I 8. Circular hole I 8 can make its torsional stiffness reducing the middle position of note plate 3 when reversing, and then the torsional deformation amount reduced between note plate 3 and cross-beam body 1, prevents its weld from ftractureing.
