Description

A kind of truck frame
Technical field
The utility model relates to a kind of new car shelf structure, particularly a kind of truck frame.Belong to transport vehicle accessory technical field.
Background technology
In the prior art, the version of automobile chassis frame has three kinds basically: straight frame, central frame (or claiming the backbone type vehicle frame) and composite type vehicle frame.Wherein use the widest with straight frame.
Straight frame is made up of two longeron and some crossbeams that are positioned at both sides, with riveting or welding process longeron and crossbeam is connected into crash-resistant rigid frame.Usually be stamped to form with low alloy steel plate, section form is generally flute profile.Its constructional feature is to be convenient to install operator's compartment, compartment and some special equipments and to arrange other assembly, helps reequiping modification of vehicle and many kinds of development automobile.Extensively be employed on goods carrying vehicle and the most speciality car.Fig. 1 shows a kind of traditional frame optimization structure, and its cross section layout and variation and the layout of crossbeam on vehicle frame are the simple process mode that equidistance is uniformly distributed with.Because vehicle carries, unbalance stress, adopts the rigidity of frame of the equal mode for cloth of this crossbeam equidistance, intensity can receive influence to a certain degree.
Summary of the invention
The purpose of the utility model is the defective to above-mentioned prior art; A kind of new car shelf structure is provided; Through arranging that preferably body frame structure for automotive that longitudinal and cross beam constitutes can obtain enough frame strengths, suitable vehicle frame rigidity, make vehicle frame before and after torsional stiffness bigger, middle less than normal; Reduce the degree of jolting of automobile, strengthened the stability and the maneuvering performance of inclination.
For realizing that the technical scheme that above-mentioned purpose the utility model is taked is: a kind of truck frame; This vehicle frame is by left longeron, right vertical beam and the some rigid frames that crossbeam connects and composes; Wherein the front end bonded assembly with said left and right longeron is first crossbeam; With the rear end bonded assembly of said left and right longeron be end beams, said framework is that leading portion is wide, stage casing and the narrow shape of back segment; One second crossbeam is located at said framework leading portion and adjacent with said first crossbeam; Many crossbeams are located at the stage casing of said framework, wherein, with the adjacent setting of said second crossbeam be the 3rd crossbeam, another crossbeam is set in place in the flat spring bracket place in said framework stage casing; One crossbeam is set in place the leaf spring hanger place in said framework back segment; Said second crossbeam and said the 3rd crossbeam adopt tubular crossbeam, and remaining said crossbeam is the grooved crossbeam.The length of said leading portion, stage casing and back segment about equally.The depth of section of said left and right longeron along its length direction be that the anterior and posterior height value is little, intermediate altitude value the earth changes, depth of section is than being 13:16:13.The crossbeam quantity that the stage casing of said framework is provided with is three.
The utility model provides a kind of later-model body frame structure for automotive array mode; Through making preferable connection location and method and the design of left and right longeron employing variable section that vehicle frame integral body is front wide and rear narrow, confirm crossbeam and longeron, can obtain good overall vehicle frame performance.The utility model body frame structure for automotive possesses enough frame strengths, suitable vehicle frame rigidity.Torsional stiffness is bigger before and after the vehicle frame, and is middle less than normal, reduced the degree of jolting of automobile, strengthened the stability and the maneuvering performance of inclination.
Description of drawings
Figure 1A and Figure 1B are the scheme drawings of a kind of traditional vehicle shelf structure of expression;
Fig. 2 is the scheme drawing of expression the utility model body frame structure for automotive;
Fig. 3 is the view of presentation graphs 2 one sides.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Shown in Fig. 1-3, the straight frame of the utility model is made up of the left longeron 8 that is positioned at the left and right sides, right vertical beam 9 and some crossbeams, adopts riveting or welding process can longeron and crossbeam be connected into crash-resistant rigid frame.If with the length of said framework, that is, the length of left and right longeron 8,9 is made as about equally three sections, i.e. leading portion, stage casing and back segment, said framework are that leading portion is wide, stage casing and the narrow shape of back segment, and wherein, the width of stage casing and back segment can be identical.What be connected in left and right longeron 8,9 front ends is first crossbeam 1, and what be connected in the rear end is end beams 7.Vicinity first crossbeam 1 place at said framework leading portion is provided with second crossbeam 2; In said framework stage casing many crossbeams are set; Wherein, with the 2 adjacent settings of second crossbeam be the 3rd crossbeam 3, another root crossbeam 5 is arranged on flat spring bracket 10 places in this stage casing; Three crossbeams can be set in this stage casing; Promptly the 3rd crossbeam 3, crossbeam 4 and crossbeam 5 also can be provided with four, even more.The leaf spring hanger place of said framework back segment is provided with a crossbeam 6.Second crossbeam 2 and the 3rd crossbeam 3 adopt tubular crossbeam, and tubular crossbeam also can be used to support the miscellaneous part on the automobile in the torsional stiffness that guarantees vehicle frame with when bearing longitudinal loading, is convenient to car load and arranges; Remaining crossbeam is the grooved crossbeam.Lower aerofoil is connected on each crossbeam and the left and right longeron.Crossbeam 5 is set at flat spring bracket 10 places, crossbeam 6 is set, can reduce the stress deformation of longeron, and because the power at flat spring bracket 10 and leaf spring hanger 11 places is very big with the commentaries on classics distance, it is big that torsion stiffness preferably is set, and connects the crossbeam of wider width at leaf spring hanger 11 places.Left and right longeron 8,9 is the variable section longeron, and the depth of section of promptly left and right longeron 8,9 changes along its length direction, and the height value of two ends is less before and after being; The shape that the intermediate altitude value is bigger; Its depth of section is than being 13:16:13, and for frame strength, distribution more is tending towards reasonable like this.Lower aerofoil is connected on each crossbeam and the longeron, has formed the better rigidity angle and has supported, and therefore can produce good diagonal ligament effect, and whole vehicle frame rigidity is increased, and the aerofoil outside can not produce warpage because of pressurized.
Above-described embodiment is a kind of of the more preferably concrete embodiment of the utility model, and common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included within the protection domain of the utility model.
