Abstract
The present invention proposes a kind of long head school bus vehicle frame, and its left and right longeron is one time punching molded monolithic construction；Left and right longeron in longitudinal direction in irregular many variable section structures, specially：It is the variable section structure for gradually narrowing from the width from the middle to both ends between back axle installation position and propons installation position to correspond in the lower end of left and right longeron；Widen downwards and the front hanger of propons is installed in the front end of left and right longeron, extend from the rear hanger position for installing propons forward on left and right longeron is the variable section structure for gradually narrowing from the width, and the front hanger of propons is transitted to, form the deformed area that can absorb impact energy structure.The deformed area that impact energy structure can be absorbed is set, and when a vehicle is in a collision, vehicle frame front end can produce larger bending deformation quantity, so as to effectively be absorbed to impulsive force；The present invention be also convenient for keeping front part of vehicle by property, save material, reduce car load deadweight, reduce car load center of gravity, improve vehicle run stability.
Description
Technical field
A kind of a kind of the present invention relates to special car body frame structure for automotive, more particularly to long head school bus vehicle frame.
Background technology
School bus is the vehicles for coming and going school for transporting student, and its safety is by social extensive concern.Require that school bus is designed using long header structure for this state compulsion, it is ensured that vehicle headstock when frontal impact is subject to can play energy-absorbing buffering and act on, to reduce the injury caused by student.
As shown in Figure 1 and Figure 2, at present, using girder construction is led directly to more than domestic 6～7 meters long head school bus vehicle frame, specially：Left straight-through longeron 1 and right straight-through longeron 2 are connected to one with connecting cross beam 3 by bolt and rivet, its middle left and right longeron is designed using contour, uiform section.The structure frame, exists：Complete vehicle weight is big, and center of gravity is high, the defect of stability difference, while when vehicle occurs side collision or knocks into the back, frame distortion amount is less, stress is concentrated and is difficult to decompose to all directions, and so as to cause occupant's risk of injury to increase, safety coefficient reduces.With regard to normal control vehicle frame design requirement, in frontal impact from cushioning effect, for the purpose of being unlikely to injure student, just should consider in Vehicle Frame Design, in addition it is also contemplated that side crash or when knocking into the back, car load stress, on human life's foundation for security is not affected, the permission deflection of vehicle stress.
Content of the invention
For overcoming defect present in existing long head school bus body frame structure for automotive, increase vehicle frame energy-absorbing effect, improve safety of school bus, the present invention proposes a kind of long head school bus vehicle frame.
For this purpose, the technical scheme is that：A kind of long head school bus vehicle frame, including left and right longeron, is fixedly connected with crossbeam by bolt and rivet between left and right longeron, it is characterised in that：Left and right longeron is one time punching molded monolithic construction, and left and right longeron is in longitudinal direction in irregularly many variable section structures；Described it is being specially in irregular many variable section structures in longitudinal direction：It is the variable section structure for gradually narrowing from the width from the middle to both ends between back axle installation position and propons installation position to correspond in the lower end of left and right longeron；Widen downwards and the front hanger of propons is installed in the front end of left and right longeron, extend from the rear hanger position for installing propons forward on left and right longeron is the variable section structure for gradually narrowing from the width, and the front hanger of propons is transitted to, form the deformed area that can absorb impact energy structure.
Beneficial effect：The present invention is designed by absorbing the deformed area of impact energy structure on left and right longeron, and when a vehicle is in a collision, the front end of vehicle frame can produce larger bending deformation quantity, so as to effectively be absorbed to impulsive force, reduces occupant's risk of injury；Also take into account reduction car load center of gravity so that car load layout is more reasonable, improve vehicle safety coefficient.The front end of left and right longeron is widened for installing hanger downwards, be easy to keep front part of vehicle by property.It is the variable section structure for gradually narrowing from the width from the middle to both ends between back axle installation position and propons installation position to correspond to, vehicle frame is made to save material while some strength is ensured, reduce car load deadweight, reduce energy expenditure, reduce chassis height, reduce vehicle and turns to probability of turning on one's side, lightweight 15-20%, raising vehicle run stability when higher speed per hour is travelled.

Fig. 2 is the top view of existing long head school bus vehicle frame.
Fig. 3 is the front view of the present invention.
Fig. 4 is the top view of the present invention.
It is numbered in figure：1. a left side leads directly to longeron；2. the right side leads directly to longeron；3. connecting cross beam；4. left longeron；5. back axle installation position；6. the rear hanger of propons；7. the front hanger of propons；8. right vertical beam；9. crossbeam；A. the deformed area of impact energy structure can be absorbed；B. the variable section structure for gradually narrowing from the width from the middle to both ends.
Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 3, Figure 4, a kind of long head school bus vehicle frame, a kind of long head school bus vehicle frame, including left longeron 4, right vertical beam 8, crossbeam 9 is fixedly connected with by bolt and rivet between left longeron 4, right vertical beam 8, left longeron 4, right vertical beam 8 are one time punching molded monolithic construction, and left and right longeron is in longitudinal direction in irregularly many variable section structures；In longitudinal direction in irregularly many variable section structures described in right, specially：It is the variable section structure B for gradually narrowing from the width from the middle to both ends between back axle installation position 5 and propons installation position to correspond in the lower end of left longeron 4, right vertical beam 8；Left longeron 4, the front end of right vertical beam 8 are widened downwards and install the front hanger 7 of propons, extend from 6 position of rear hanger for installing propons forward on left longeron 4, right vertical beam 8 is the variable section structure for gradually narrowing from the width, and the front hanger 7 of propons is transitted to, form the deformed area A that can absorb impact energy structure.
The present invention and arranges the deformed area that can absorb impact energy structure by by left and right longeron using middle width two is narrow and irregular variable section structure design that widen in front end downwards in front end, and when a vehicle is in a collision, vehicle frame can produce larger bending deformation quantity（When impact load along frame member axially loaded when, longitudinal beam deformed area is used for promoting the flexural deformation of frame member；When impact load is carried along the longitudinal direction of frame member, longitudinal beam deformed area is used for the linear deformation for promoting frame member）, so as to effectively be absorbed to impulsive force, reduce occupant's risk of injury；This design also takes into account reduction car load center of gravity so that car load layout is more reasonable, improves vehicle safety coefficient；The front end of left-right longeron is widened for installing the first hanger downwards, be easy to keep front part of vehicle by property.
