Detailed description of the invention
Below in conjunction with the elaboration that Fig. 4 ~ Fig. 9 carries out specifically to technical scheme provided by the invention, arbitrary technological means provided by the invention is carried out replace or all should within protection scope of the present invention by the technical scheme that two or more technological means or technical characteristic carry out mutually combining and obtain provided by the invention arbitrarily.
See Fig. 4 ~ Fig. 6, the embodiment of the present invention provides a kind of chassis frame (or referred to as " vehicle frame "), on the Width of chassis frame, it is different with the cross sectional shape of the second box-structure 2 with the 3rd box-structure 3, first box-structure 1 that chassis frame comprises the first box-structure 1, second box-structure 2 be linked in sequence; First box-structure 1 is for arranging that chassis frame is dissymmetrical structure in the direction of the width for arranging transmission shaft 5 and propelling rod 7 below transmission shaft 5 and oil pump 4, second box-structure 2.
Oil pump 4 and transmission shaft 5, be specially main driving axle herein, requires the space that the lower shoe of vehicle frame is given by, and can design the structure of the first box-structure 1 based on this; The axle suspension system that car hosit adopts, the space requiring the lower shoe of relevant position vehicle frame to reserve propelling rod 7 to move up and down, can design the structure of the 3rd box-structure 3 based on this.
The direction in cross section mentioned above specifically can see hereinafter A-A cross section, B-B cross section and C-C cross section.
Rational cross section is arranged, for transmission shaft 5 and the angle design of axletree horizontal surface provide enough spaces.
Technique scheme, on the Width of chassis frame, whole chassis frame be divide into three parts, each several part can based on the part design of corresponding installation structure separately and shape, and the structure of each several part is dissymmetrical structure in the direction of the width, and unsymmetric structure is made in vehicle frame local, need to arrange that the space of oil pump 4 and transmission shaft 5 is larger, opposite side space is less, has both met system layout requirement, controls vehicle frame weight to greatest extent again.Further, also avoid Each part in prior art and unanimously cause the problem of redundancy.Further, technique scheme makes the thinking of Vehicle Frame Design more flexible, meets the design requirement of miscellaneous part to greatest extent, promotes the Performance And Reliability of car load; With chassis whole layout and lift heavy performance for edge-restraint condition, the design of lightweight ultimate attainmentization is carried out to vehicle frame, can greatly reduce vehicle frame weight.
See Fig. 7, the cross sectional shape of the first box-structure 1 is the platy structure with rectangular aperture 11.And along the working direction of chassis frame, the section width size that the first box-structure 1 is positioned at the revolving seat ring line of centers side of chassis frame is greater than the section width size of opposite side, i.e. W1>W2.W1, W2 are the transverse cross-sectional width of vehicle frame advance travel direction.In order to arrange transmission shaft 5 and oil pump 4 and oil pipe thereof, the box in A-A cross section is compressed, and in order to ensure rigidity, the intensity in cross section, for the box feature in A-A cross section, the multi-box type section form of employing as shown in Figure 7.
See Fig. 8, the cross sectional shape of the second box-structure 2 is the platy structure with trapezoid-shaped openings 21.In order to arrange transmission shaft 5 and propelling rod 7 (being specially vehicle frame V-arrangement propelling rod), B-B cross section box is because near seat ring annex, chassis frame is subject to larger moment of flexure, for ensureing enough bending resistant section coefficients, during design, box is herein amplified as far as possible, adopt grooved bottom board section form as shown in Figure 8.
First box-structure 1, second box-structure 2 of vehicle frame, because there is the sudden change in cross section, easily produces stress in intermediate location and concentrates, be optimized design herein, make load and moment evenly pass to supporting leg square chest by vehicle frame to variable cross-section box type intermediate location.Transition between cross section can realize according to following scheme: there is transition connecting structure between the first box-structure 1 and the second box-structure 2, and the mode that such as employing rounding off equal stress is less realizes the transition between two box-structures.Or, auxiliary reinforcing structure is there is between first box-structure 1 and the second box-structure 2, auxiliary reinforcing structure is specifically as follows reinforced rib, brace panel or strengthens housing, reinforced rib, brace panel can be set directly between two box-structures, strengthen housing and can be located at outside the junction between two box-structures.Or, be greater than the first box-structure 1 by intensity between the first box-structure 1 and the second box-structure 2 and be connected with the material of the intensity of the second box-structure 2, such as adopt the steel that the trade mark is large to connect.
Or, adopt following manner:
The sectional dimension gradual change of the first box-structure 1, and rounding off between the first box-structure 1 and the second box-structure 2.And/or, the sectional dimension gradual change of the second box-structure 2, and rounding off between the first box-structure 1 and the second box-structure 2.
In like manner, because there is the sudden change in cross section between 3rd box-structure 3 and the second box-structure 2, also easily produce stress in intermediate location to concentrate, design can be optimized to variable cross-section box type intermediate location, make load and moment evenly pass to supporting leg square chest by vehicle frame.Transition between cross section can realize according to following scheme: there is transition connecting structure between the 3rd box-structure 3 and the second box-structure 2, and the mode that such as employing rounding off equal stress is less realizes the transition between two box-structures.Or, auxiliary reinforcing structure is there is between 3rd box-structure 3 and the second box-structure 2, auxiliary reinforcing structure is specifically as follows reinforced rib, brace panel or strengthens housing, reinforced rib, brace panel can be set directly between two box-structures, strengthen housing and can be located at outside the junction between two box-structures.Or the material being greater than the intensity of the second box-structure 2 and the 3rd box-structure 3 between the 3rd box-structure 3 with the second box-structure 2 by intensity is connected, the steel that the trade mark is large are such as adopted to connect.
Or, adopt following manner:
The sectional dimension gradual change of the second box-structure 2, and rounding off between the second box-structure 2 and the 3rd box-structure 3.And/or, the sectional dimension gradual change of the 3rd box-structure 3, and rounding off between the second box-structure 2 and the 3rd box-structure 3.
See Fig. 9, the cross sectional shape of the 3rd box-structure 3 is rectangle.Vehicle frame afterbody is subject to larger torsion near the position of rear fixed supporting leg and is not subject to the restriction in rear suspension component movement space, adopts square-section can obtain the cross section bending resistance torsional property larger than grooved bottom board cross section.
Above-mentioned chassis frame, propose a kind of asymmetric and Crane Truck Chassis vehicle frame of variable cross-section form, traditional symmetrical uniform cross section form vehicle frame is innovated, according to the needs of lift heavy vehicle frame stress Finite element analysis results and chassis power and hydraulic efficiency pressure system layout, eliminate redundancy material, under ensureing the prerequisite that Rigidity and strength meets design requirement, reduce vehicle frame weight to greatest extent.
The embodiment of the present invention also provides a kind of car hosit, comprises the chassis frame that the arbitrary technical scheme of the present invention provides.
Above-mentioned car hosit, owing to have employed above-mentioned chassis frame, under the prerequisite of lift heavy performance requriements meeting car load, weight reduces greatly.
