Preferably, the cross-sectional area of described longitudinal beam front section and longeron back segment is less than the cross-sectional area in longeron stage casing, and the height of described longitudinal beam front section and longeron back segment is lower than the height in longeron stage casing.
Preferably, outside two described longerons, the position of corresponding described rear suspension front cross rail and rear suspension after cross member is respectively equipped with and hangs spacing beam, two spacing that hang between spacing beam of described rear suspension front cross rail both sides are 952 ± 2mm, and two spacing that hang between spacing beam of described rear suspension after cross member both sides are also 952 ± 2mm.
Preferably, the described transmission shaft crossbeam that suspends comprises sheet under crossbeam upper slice and H type crossbeam, described crossbeam upper slice is connected with the top of sheet under described H type crossbeam, the two ends of described crossbeam upper slice are connected with the top of described two longerons, and under described H type crossbeam, the two ends of sheet are connected with the bottom of described two longerons.
Preferably, described front cross rail, rear suspension front cross rail, rear suspension after cross member and transom beam are straight crossbeam.
Compared with prior art, the beneficial effect of automotive frame assembly of the present utility model is as follows:
(1) because two longerons form leading portion Kuan Xing district and back segment Zhai Xing district, and, distance between two longeron outsides described in leading portion Kuan Xing district is 856 ± 2mm, distance between two longeron outsides described in back segment Zhai Xing district is 800 ± 2mm, the design of this size not only can meet installs the requirement of high-power size driving engine, also can meet the requirement that oversize tyre is installed, and the design that is greater than the distance between two longerons outsides in back segment Zhai Xing district in the distance between two longerons outsides in leading portion Kuan Xing district can increase the intensity of longeron simultaneously; Because the wheelspan of front axle is 806 ± 2mm, the distance suspending between controlling point of two brackets is 503 ± 2mm, therefore meet the installation requirement of expanded letter operator's compartment.
(2) be less than the cross-sectional area in longeron stage casing due to the cross-sectional area of longitudinal beam front section and longeron back segment, and the height of longitudinal beam front section and longeron back segment is lower than the height in longeron stage casing, the height that middle part arranges can bear compared with large twisting resistance compared with high longeron stage casing and indeformable, meet requirement of strength, and arranging highly lower longitudinal beam front section and longeron back segment, two ends can alleviate the weight of vehicle frame, realize underloading high speed goods transport, improve conveying efficiency, save haulage time.
(3) hang spacing beam owing to arranging, and two spacing that hang between spacing beams are 952 ± 2mm, can meet arrangement.
(4) because the transmission shaft crossbeam that suspends is made up of sheet under crossbeam upper slice and H type crossbeam, thus relatively simple for structure, easy for installation, and load-carrying capacity is strong.
(5) because front cross rail, rear suspension front cross rail, rear suspension after cross member and transom beam are straight crossbeam, simple in structure, easily manufactured, reduce manufacturing cost.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Brief description of the drawings
