Technical field
The utility model relates to engineering machinery field, particularly a kind of vehicle frame and have the engineering truck of this vehicle frame.
Background technology
In various engineering trucks, mixermobile is a kind of special-purpose heavy-duty vehicle of concrete transportation, and its domestic shipping weight is larger, and vehicle frame plays a part each parts that supporting connects Mixer Truck, bears from the various load inside and outside the car in total.Difference according to user demand, the capacity of the mixer barrel of mixermobile is also different, and the conventional method that increases the mixer barrel geometric volume is to realize by the length that increases the mixer barrel middle cylindrical section, so along with the increase of mixer barrel volume, the length of mixer barrel is just more and more longer.Because mixer barrel tilts to be installed on the vehicle frame by certain angle, so the capacity of mixer barrel is larger, then car load length is longer, vehicle frame is also just longer simultaneously.
Traditional whole segmentation vehicle frame manufacture craft needs to cut out, the steps such as cutting and punching press in processing longeron process, and manufacture craft is poor, has the lot of materials waste, and the accessory commonality of the vehicle frame measured of difference side is relatively poor, causes production efficiency lower.
The utility model content
In view of this, the utility model is intended to propose a kind of vehicle frame and engineering truck, to reduce the production difficulty of vehicle frame, enhances productivity.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of vehicle frame comprises longeron and is connected to crossbeam between the longeron that described longeron comprises longitudinal beam at front section of automobile, stage casing longeron and the back segment longeron that sequentially connects, the two ends of described stage casing longeron respectively with longitudinal beam at front section of automobile and back segment longeron overlap joint.
Further, the two ends of described stage casing longeron are overlapped on respectively the outside of longitudinal beam at front section of automobile and back segment longeron.
Further, described back segment longeron is overlapped on the longeron outside, stage casing, and this stage casing longeron is overlapped on the described longitudinal beam at front section of automobile outside.
Further, described longitudinal beam at front section of automobile, stage casing longeron and back segment longeron include web and wing plate, and this wing plate is vertically set on the both sides of this web.
Further, described longitudinal beam at front section of automobile, stage casing longeron and back segment longeron have at least one to be holistic beam texture.
Further, described longitudinal beam at front section of automobile, stage casing longeron and back segment longeron have a beam texture for being combined by the beam more than two sections at least.
Further, be connected connection mode with the back segment longeron be that welding, riveted joint or bolt are connected for described stage casing longeron and longitudinal beam at front section of automobile.
A kind of engineering truck is provided with aforesaid vehicle frame.
Further, described engineering truck comprises Mixer Truck.
With respect to prior art, the utlity model has following advantage:
1, vehicle frame described in the utility model adopts three segments combined body frame structure for automotive, be conducive to the vehicle frame modular combination and produce, and each section longeron processes separately, is easy to control accuracy, has reduced manufacture difficulty, is conducive to enhance productivity.
2, vehicle frame described in the utility model, the connection bit of its stage casing longeron and longitudinal beam at front section of automobile and back segment longeron is equipped with overlapping portion, for different Mixer Truck vehicles, the length of overlapping portion is also different, the Rational choice superposed positions can remedy the design defect of the abrupt change of cross-section between subframe and the vehicle frame, thereby has guaranteed the strength demand of vehicle frame.
3, vehicle frame described in the utility model, adopt three segments combined body frame structure for automotive, the multi-form vehicle frame production and processing technologies such as low early and high after, front wide and rear narrow have been simplified, the shortcoming that the lot of materials of having avoided whole segmentation longeron to cause owing to the manufacture craft problem in the course of processing is wasted, greatly improve stock utilization, reduced productive costs.
