For achieving the above object, the utility model adopts following technical scheme: the superduty automobile chassis frame, two longerons and the crossbeam that between two longerons, connects about comprising, it is characterized in that described longeron is made of superposed channel-section rail of one deck at least and the Z-shaped beam of one deck that is positioned at the bottom, adopt welding manner to connect between the adjacent two layers channel-section rail on described top, the employing welding manner is connected between channel-section rail and the Z-shaped beam.
Described channel-section rail is preferably two-layer up and down.
In such scheme, the length of described Z-shaped beam is more preferably greater than the length of lower floor's channel-section rail, and the length of lower floor's channel-section rail is greater than the length of upper strata channel-section rail.
Above-mentioned upper and lower two-layer channel-section rail is that front end or rear end are ladder-like arranged successively with the preferred arrangement of the Z-shaped beam of one deck that is positioned at the bottom.
In such scheme, described crossbeam can be made of entablatrance and cross sill, the two ends of entablatrance respectively with about channel-section rail in two longerons be connected with Z-shaped beam, the two ends of cross sill respectively with about Z-shaped beam bottom in two longerons be connected.
Above-mentioned entablatrance can be the rectangular box-like crossbeam of cross-sectional plane, and above-mentioned cross sill can be the rounded tubular crossbeam of cross-sectional plane.
The two ends of described box-like crossbeam can be welded with adapter plate, and adapter plate surface configuration longeron surface configuration cooresponding with it matches, and the two ends of described tubular crossbeam can be welded with mount pad, and its cooresponding longeron surface configuration of the shape of mount pad locating surface matches.
Longeron of the present utility model adopts the combination longeron of Z-shaped and two kinds of section forms of flute profile, the channel-section rail of longeron adopts the variable section form, can adjust channel-section rail depth of section and length according to the difference of car load, the position bigger to load (normally vehicle frame afterbody) increases the channel-section rail depth of section or adopts the double flute ellbeam.For reducing vehicle frame weight, (normally vehicle frame front portion) can adopt single channel-section rail maybe need not increase channel-section rail at the less position of load.For guaranteeing the crossing ability of vehicle, can be in the vehicle frame front portion by car load requirement designing car frame angle of attach.The utility model is by selecting rational cross section parameter, and the beam that makes two kinds of section forms forms light weight, combination longeron that intensity is high after the welding combination.Compare with the longeron of existing single cross section type, the longeron after the combination has higher Combination property, but actv. improves the degree of utilization of material, reaches the requirement of light-weight design.Be connected horizontal direction and the vertical direction of crossbeam and longeron form framed structure, have improved the strength and stiffness of vehicle frame, make it have higher load-carrying capacity.
By alignment measurement in kind, adopt the described superduty automobile chassis frame of this utility model to compare with former Z-shaped frame assembly, under the essentially identical situation of unit cross section quality, single bridge axle load ability of car load is brought up to 13000kg by original 11300kg.

The specific embodiment
The utility model by about the longeron 1 of two symmetrical structures and the crossbeam that between two longerons, connects form.Upper and lower two-layer channel-section rail (11,12) is adopted on longeron 1 top, and two-layer channel-section rail adopts welding manner to connect; The Z-shaped beam 13 of maximum section of passenger flow is adopted in the bottom, and two parts adopt welding manner to connect up and down.The channel-section rail of longeron 1 adopts the variable section form, can adjust channel-section rail depth of section and length according to the difference of car load, and the position bigger to load (normally vehicle frame afterbody) adopts the double flute ellbeam.For reducing vehicle frame weight, (normally vehicle frame front portion) adopts single channel-section rail maybe need not increase channel-section rail at the less position of load, and as shown in Figure 6, channel-section rail is not adopted in the vehicle frame front portion, and single channel-section rail is adopted at the middle part, and afterbody adopts the double flute ellbeam.For guaranteeing the crossing ability of vehicle, can be in the vehicle frame front portion by car load requirement designing car frame angle of attach.
Cross member of frame is made of entablatrance and cross sill, and entablatrance is the rectangular box-like crossbeam 2 of cross-sectional plane, and cross sill is the rounded tubular crossbeam 3 (as shown in Figure 7) of cross-sectional plane.Tubular crossbeam 3 can be designed to straight tube or bend pipe according to the car load arrangement requirement, and can require to adjust pipe external diameter and wall thickness according to Frame Load, and tubular crossbeam 3 two ends are welded with mount pad 4, are used for being connected with longeron 1.Box-like crossbeam 2 is welded by steel plate, and two ends are welded with adapter plate 5 (as shown in figure 11), can adjust box-like crossbeam oad and sheet metal thickness according to Frame Load and installation requirement.
