This carrying pole type cross member of frame structure, comprise the cross-beam body of U-shaped profile, be fixedly welded on the end plate at two ends, cross-beam body left and right respectively, be arranged at some mounting holes on end plate and four L-shaped gussets, the middle part, baseplane of cross-beam body is provided with some circular holes II, its two ends place, left and right, baseplane is respectively arranged with circular hole III, two gusset lower ends are fixedly welded in cross-beam body left end two inner side plane, its external side end is fixedly welded on the end plate in left side, another two gusset lower ends are fixedly welded in cross-beam body 1 right-hand member two inner side plane, its external side end is fixedly welded on the end plate on right side, two end plates utilizes threaded fasteners to be fixed on two spring blocks of two ends, chassis side rail left and right installation respectively by mounting hole, described cross-beam body is provided with to recessed groove.
In order to improve torsional stiffness, also comprise the note plate in X-shaped, four edges of note plate are 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, above-mentioned gusset lower end is respectively arranged with some plug welding holes I.
In order to prevent weld from ftractureing, the middle part of above-mentioned note plate is provided with circular hole I.
The beneficial effects of the utility model are: the cross-beam body of U-shaped possesses good anti-torsion performance, improves reliability, and lightweightly reduce manufacturing cost.And gusset can play the Joint strenght between deep beam body and end further.Circular hole II can make cross-beam body reduce the torsional stiffness of middle part when reversing, and then position, intermediate portion torsional deflection amount is strengthened, and prevents cross-beam body two ends to be out of shape the excessive situation causing occurring with end plate weld to ftracture.And the circular hole III that cross-beam body two ends are arranged can make the stress produced during torsional deflection be released, improve the reliability of use.Cross-beam body is provided with to recessed groove, the space between therefore can effectively increasing bottom transmission shaft and change speed gear box, prevents to interfere.

Detailed description of the invention
Be described further below in conjunction with accompanying drawing 1 to accompanying drawing 4 pairs of the utility model.
As shown in Figures 1 and 2, this carrying pole type cross member of frame structure, comprise the cross-beam body 1 of U-shaped profile, be fixedly welded on the end plate 2 at cross-beam body about 1 two ends respectively, be arranged at some mounting holes 6 on end plate 2 and four L-shaped gussets 4, the middle part, baseplane of cross-beam body 1 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 gusset 4 lower ends are fixedly welded in cross-beam body 1 left end two inner side plane, its external side end is fixedly welded on the end plate 2 in left side, another two gusset 4 lower ends are fixedly welded in cross-beam body 1 right-hand member two inner side plane, its external side end is fixedly welded on the end plate 2 on right side.As shown in Figure 4, two end plates 2 utilizes threaded fasteners to be fixed on two spring blocks 12 of chassis side rail about 11 two ends installation respectively by mounting hole 6, the cross-beam body 1 of U-shaped possesses good anti-torsion performance, improves reliability, and lightweightly reduces manufacturing cost.And gusset 4 can play the Joint strenght between deep beam body 1 and end 2 further.Circular hole II 9 can make cross-beam body 1 reduce the torsional stiffness of middle part when reversing, and then position, intermediate portion torsional deflection amount is strengthened, and prevents cross-beam body 1 two ends to be out of shape the excessive situation causing occurring with end plate 2 weld to ftracture.And the circular hole III 10 that cross-beam body 1 two ends are arranged can make the stress produced during torsional deflection be released, improve the reliability of use.Cross-beam body is provided with to recessed groove, the space between therefore can effectively increasing bottom transmission shaft and change speed gear box, prevents to interfere.
