Description
Technical field:
The present invention relates to motor vehicle assembly field, relate generally to the frame structure of a kind of chassis assembly.
Background technology:
Chassis frame structure is the important composition parts on automobile, and it mainly carries supporting role, for installing the master of vehicle body
Wanting component, therefore the attachment structure of vehicle frame itself needs have good steadiness, it is understood that existing crossbeam is all direct
Be welded on longeron its, the stress of its solder joint is excessive, the situation of fracture often occurs, and impact is normal to be used, and needs repair welding, and
And the bearing capacity again welded was not as in the past, it is easier to damage.Chassis frame structure not only undertakes supporting role, and at vapour
When car collides, chassis frame structure also to have the effect absorbing collision energy, and when impact force is bigger, automobile frame is tied
Structure also needs to have cushioning effect, to avoid bigger impact force to cause damage driver and crew.Chassis of the prior art frame
Shelf structure, it is impossible to effectively meet above-mentioned requirements, when collision scenario, it is impossible to meets the requirement absorbing collision energy, is touching
When power of hitting is bigger, cushioning effect is the most poor.
Summary of the invention:
The object of the invention is contemplated to make up the defect of prior art, it is provided that the frame structure of a kind of chassis assembly.
The present invention is achieved by the following technical solutions:
The frame structure of a kind of chassis assembly, includes main frame, and described main frame is by two longerons, it is characterised in that: described
Crossbeam spaced apart is installed between two longerons, described crossbeam both ends endoporus is provided with elastic limit device, and front
It is separately installed with crash bar outside the main beam of rear end and longeron, described crash bar is respectively installed with induced erosion control sleeve pipe
Part, described induced erosion control sleeve part includes body, and the plastic hinge that bend inwards and outwards bend is distributed on described body
Line, the shape of neighbouring two folding surfaces of described yield line is all triangle or trapezoidal, and moulding twisted wire left and right adjacent two mutually
Folding surface be shaped as triangle and trapezoidal.
Described elastic limit device includes deck, and the middle part of described deck is provided with installing hole, the surrounding of described deck
Cooperation is distributed in pilot hole, and pilot hole guide pillar is installed, described guide pillar is set with spring, and guide pillar with on each crossbeam
Pilot hole coordinates.
Being set with branch sleeve on the end of described crossbeam, one end of described branch sleeve is provided with installing plate, described peace
Installing hole is distributed on dress plate, location hole that remaining crossbeam outer wall on installing hole coordinate on described branch sleeve, is distributed.
The elastic limit device that the application is provided with in passing through the connection assembly in length and breadth and between crossbeam and crossbeam itself
Structure, can fix stable for crossbeam being connected with longeron, weld, be first sleeved on crossbeam by branch sleeve, then
Elastic limit device is arranged in crossbeam, is fixed in by its internal structure and is inlaid in the installing hole that longeron is corresponding
In, due to the structure of the spring in elastic limit device, by pressing the limiting plate of guide pillar end, then it is fed into longeron
Installing hole in, due to the rebound reset of spring, crossbeam can be fixed on longeron, then weld, the most again by joining
It is fixing that conjunction branch sleeve carries out step to it, by inside and outside cooperation, can complete the whole firm connection of vehicle body, by many-side
Connection fixing and spacing, add the connection stationary plane of longitudinal and cross beam, convenient welding simultaneously, and itself structure be simple
Single, lightweight, while not increasing weight, it is ensured that the steadiness of vehicle frame itself.
It is simultaneously based on thin-wall pipe flexing energy-absorbing principle, devises the induced erosion control sleeve part with special shape, logical
Cross induced erosion control sleeve part and self deform the process of stepping down, the impact damage that reply carrier frame outward flange suffers timely
And quickly absorb its impact energy carried, thus play the effect of protection, described induced erosion control sleeve part bearing capacity and energy-absorbing
Measuring and obtained with calculating by energy-absorbing theory analysis, its protection is big, higher than energy-absorbing, and energy absorption is big, and overall energy-absorbing effect is good.
The invention have the advantage that
Present configuration is simple, lightweight, while not increasing weight, uses the spacing of multiple direction both to facilitate welding,
By adding the contact area of connection, good stability, disperses the bearing capacity of welding portion simultaneously, and uses special construction
Safeguard structure, uses the principle of energy-absorbing, alleviates impact force, thus play the effect of protection.
