Referring to Fig. 4~Fig. 6, the embodiment of the present invention provides a kind of chassis frame (or being referred to as " vehicle frame "), advances in vehicle
On direction, chassis frame includes the first box-structure 1, the second box-structure 2 and the 3rd box-structure 3 being linked in sequence, first
Box-structure 1 is different with the cross sectional shape of the second box-structure 2；First box-structure 1 is used to arrange power transmission shaft 5 and oil pump 4, the
The lower section of two box-structure 2 is used to arrange power transmission shaft 5 and distance rod 7, and chassis frame is dissymmetrical structure in the direction of the width.
Oil pump 4 and power transmission shaft 5, herein specially final drive shaft, it is desirable to the space that the lower shoe of vehicle frame is given by, are based on
This can design the structure of the first box-structure 1；The axle suspension system that autocrane is used, it is desirable to relevant position vehicle frame
Lower shoe reserves the space that distance rod 7 is moved up and down, and the structure of the 3rd box-structure 3 can be designed based on this.
The direction in section described above specifically may refer to Section A-A, section B-B and C-C sections hereinafter.
Rational section arrangement, enough spaces are provided for the angle design of power transmission shaft 5 and axletree horizontal plane.
Above-mentioned technical proposal, in vehicle forward direction, three parts is divide into by whole chassis frame, each several part can be with base
In the respective structure of the part design of corresponding installation and shape, the structure of each several part is dissymmetrical structure in the direction of the width,
Vehicle frame is made locally unsymmetric structure, it is necessary to arrange that the space of oil pump 4 and power transmission shaft 5 is larger, opposite side space is smaller, both meets
System arrangement requirement, and vehicle frame weight is controlled to greatest extent.And, it is thus also avoided that Each part is consistent in the prior art
And the problem of cause redundancy.Also, above-mentioned technical proposal makes the thinking of Vehicle Frame Design more flexible, and other are met to greatest extent
The design requirement of part, lifts the Performance And Reliability of vehicle；Using chassis integral layout and lift heavy performance as edge-restraint condition,
The design of lightweight ultimate attainmentization is carried out to vehicle frame, vehicle frame weight can be substantially reduced.
Referring to Fig. 7, the cross sectional shape of the first box-structure 1 is the platy structure with rectangular aperture 11.And along chassis
Frame width direction, the cross-sectional width size that the first box-structure 1 is located at the revolving seat ring center line side of chassis frame is more than
The cross-sectional 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 biography
Moving axis 5 and oil pump 4 and its oil pipe, the box of Section A-A are compressed, in order to ensure rigidity, the intensity in section, for Section A-A
Box feature, the multi-box type section form of use is as shown in Figure 7.
Referring to 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 biography
Moving axis 5 and distance rod 7 (being specially vehicle frame V-arrangement distance rod), section B-B box because close to seat ring annex, chassis frame by
Larger moment of flexure, to ensure enough bending resistant section coefficient, tries one's best box herein amplification during design, using grooved bottom board section
Face form is as shown in Figure 8.
First box-structure 1 of vehicle frame, the second box-structure 2 are also easy to produce because there is the mutation in section in intermediate location
Stress concentration, optimizes design to variable cross-section box type intermediate location herein, load and torque is passed to uniformly through vehicle frame
Supporting leg square chest.Transition between section can be realized according to following scheme：Between first box-structure 1 and the second box-structure 2
There is transition connecting structure, such as the transition between two box-structures is realized using the less mode of rounding off iso-stress.
Or, there is auxiliary reinforcing structure between the first box-structure 1 and the second box-structure 2, auxiliary reinforcing structure is specifically as follows
Reinforcement, reinforcing plate strengthen housing, and reinforcement, reinforcing plate can be arranged directly between two box-structures, strengthen housing
It can be located on the outside of the junction between two box-structures.Or, between the first box-structure 1 and the second box-structure 2
The material for being more than the intensity of the first box-structure 1 and the second box-structure 2 by intensity is connected, such as using the big steel of the trade mark
Connection.
Or, using following manner：
Round and smooth mistake between the sectional dimension gradual change of first box-structure 1, and the first box-structure 1 and the second box-structure 2
Cross.And/or, round and smooth mistake between the sectional dimension gradual change of the second box-structure 2, and the first box-structure 1 and the second box-structure 2
Cross.
Similarly, because there is the mutation in section, in intermediate location between the 3rd box-structure 3 and the second box-structure 2
Stress concentration is also easy to produce, design can be optimized to variable cross-section box type intermediate location, makes load and torque uniformly through vehicle frame
Pass to supporting leg square chest.Transition between section can be realized according to following scheme：3rd box-structure 3 and the second box-structure
There is transition connecting structure between 2, such as the use less mode of rounding off iso-stress is realized between two box-structures
Transition.Or, there is auxiliary reinforcing structure between the 3rd box-structure 3 and the second box-structure 2, auxiliary reinforcing structure specifically may be used
Think reinforcement, reinforcing plate or strengthen housing, reinforcement, reinforcing plate can be arranged directly between two box-structures, strengthen
Housing can be located on the outside of the junction between two box-structures.Or, the 3rd box-structure 3 and the second box-structure 2
Between the second box-structure 2 and the 3rd box-structure 3 are more than by intensity the material of intensity connect, such as it is big using the trade mark
Steel are connected.
Or, using following manner：
Round and smooth mistake between the sectional dimension gradual change of second box-structure 2, and the second box-structure 2 and the 3rd box-structure 3
Cross.And/or, round and smooth mistake between the sectional dimension gradual change of the 3rd box-structure 3, and the second box-structure 2 and the 3rd box-structure 3
Cross.
Referring to Fig. 9, the cross sectional shape of the 3rd box-structure 3 is rectangle.Vehicle frame afterbody close to the position of rear fixed supporting leg by
Reversing and not restricted by rear suspension component movement space to larger, can obtain cutting than grooved bottom board using square-section
The bigger section bending resistance torsional property in face.
Above-mentioned chassis frame, it is proposed that a kind of asymmetric and variable cross-section form Crane Truck Chassis vehicle frame, to tradition
Symmetrical uiform section form vehicle frame innovated, according to lift heavy vehicle frame stress Finite element analysis results and chassis power and hydraulic pressure
The need for system layout, redundancy material is rejected, it is ensured that on the premise of rigidity and intensity meet design requirement, reduce to greatest extent
Vehicle frame weight.
The embodiment of the present invention also provides a kind of autocrane, including the chassis vehicle that any technical scheme of the invention is provided
Frame.
Above-mentioned autocrane, as a result of above-mentioned chassis frame, in the premise for the lift heavy performance requirement for meeting vehicle
Under, weight is substantially reduced.
