Further, two longerons of described stage casing vehicle frame outwards broaden at mixer barrel inner cone place.
Further, in order to strengthen the strength and stiffness of the described section of extending out vehicle frame, be provided with the crossbeam of captiveing joint with described two longerons between the described section of extending out vehicle frame two longerons of described concrete mixer truck vehicle frame.
Further, the crossbeam between vehicle frame two longerons of described stage casing can be one or more.
Further, the crossbeam between described connection two longerons is provided with depressed part near mixer barrel one side, and described depressed part is the circular arc that adapts with mixer barrel.
Further, described stage casing vehicle frame is provided with subframe, and described subframe can be connected on the vehicle frame of described stage casing by welding or bolt.
Further, described back segment vehicle frame is inclined upwardly with respect to front section bicycle frame.
Further, described front section bicycle frame longeron, stage casing chassis side rail and back segment chassis side rail are the integral type structure.
Again by welding or bolt captive joint, perhaps welding was connected with bolt and uses after described front section bicycle frame longeron, stage casing chassis side rail and back segment chassis side rail were produced separately and finished further.
Above-mentioned concrete mixer truck vehicle frame can effectively reduce the height of concrete mixer truck, has increased side's amount of concrete mixer truck, reduces simultaneously the center of gravity of mixer barrel, has solved the easily problem of rollover of concrete mixer truck.
On the other hand, the utility model also provides a kind of concrete mixer truck, and described concrete mixer truck comprises above-mentioned concrete mixer truck vehicle frame.

The specific embodiment
Need to prove that in the situation of not conflicting, embodiment and the feature among the embodiment in the utility model can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
Basic thought of the present utility model is: in the height that reduces concrete mixer truck, do not affect carrying capacity and the frame strength of concrete mixer truck, can be good at reducing the center of gravity of concrete mixer truck, thereby prevent that concrete mixer truck from rollover occuring lead to a disaster.
Below in conjunction with Fig. 1 to Fig. 4, preferred embodiment of the present utility model is described in further detail:
Need to prove, in this part, described " front ", " in " reach " afterwards " for vehicle body, described operator's compartment direction is " front ", the operator's compartment opposite sense is " afterwards ", between " front " and the part between " afterwards " be " in ".
In one embodiment, as depicted in figs. 1 and 2, the concrete mixer truck vehicle frame, comprise front section bicycle frame 2, stage casing vehicle frame 4, back segment vehicle frame 9, described front section bicycle frame 2 is used for installing operator's compartment, one end of described stage casing vehicle frame 4 is connected with described aforementioned front section bicycle frame 4, the other end of described stage casing vehicle frame 4 connects described back segment vehicle frame 9, two girder spaces of described stage casing vehicle frame 4 broaden, be used for accommodating the inner cone of mixer barrel 8, a part that is mixer barrel 8 closes in the vehicle frame, thereby reduces the whole height of concrete mixer truck, and is narrowing with described back segment vehicle frame 9 junctions.Described foreground 1 is positioned at described operator's compartment back, is used for installing water supply system and mixer barrel drive system.Described backstage 5 is positioned on the back segment vehicle frame 9, is used for supporting mixer barrel 8 discharging systems.
