Abstract
The invention relates to a bending frame longitudinal beam for passenger cars, which comprises a longitudinal-beam frame body; and the bending frame longitudinal beam for passenger cars is characterized in that a sunken section and a floating-up section are distributed on the longitudinal-beam frame body, so that the longitudinal-beam frame body is arranged in a wave-crest shaped fluctuation mode; and meanwhile, the initial area of the sunken section is provided with auxiliary fasteners, and the finished area of the floating-up section is provided with an external component connecting assembly. Therefore, both the bending-torsion resisting capacity and running safety of a complete car are ensured, and the height of a floor can be reduced, thereby facilitating the getting-on-and-off of passengers. By using the design above, the wheel base of a car can be increased from 3300 mm to 3935 mm, thereby improving the running comfortableness and stability of the car; and meanwhile, the occurrence of 'braking nose-dive' and 'staring backward-bending' can be reduced, and the capsizing resisting capacity is also improved.
Description
Technical field
The present invention relates to a kind of chassis side rail, relate in particular to a kind of passenger vehicle and use the bending-type chassis side rail.
Background technology
Vehicle frame is also claimed crossbeam, and the matrix of automobile generally is made up of two longerons and several crossbeams, is bearing on the wheel via suspension gear, propons, back axle, has enough strength and stiffness with load of bearing automobile and the impact of transmitting from wheel.
The desired rigidity of vehicle frame just is built on the non-deformability of vehicle frame in fact, just refers to the drag that vehicle frame is crooked for influenced by external force or reverse.In case the vehicle frame rigidity is not enough, handlingly just can be affected.Epoch was poor when the front-wheel of justing think caused turning to because of vehicle frame distortion, or tire is bad and have influence on tracking property and earth-grasping force etc. with ground-surface ground connection property, all can make road-holding property can't give play to original level certainly.
But existing vehicle frame, when particularly its longeron came for motor omnibus, anti-twist performance was not high, driving comfort and less stable; And, occurring easily nodding reducing glancing impact, layback also can appear when starting, and resistance to capsizing is also lower.
Summary of the invention
The objective of the invention is to overcome the above problem that prior art exists, provide a kind of passenger vehicle to use the bending-type chassis side rail.
Technical solution of the present invention is: a kind of passenger vehicle is used the bending-type chassis side rail, includes the longeron frame body, it is characterized in that: be distributed with sinking section and come-up section on the described longeron frame body, the longeron frame body is the crest shape and rises and falls; The place, initiation region of said sinking section is provided with assisted fasteners, and the end region place of said come-up section is provided with the external components coupling assembling.
Further, above-mentioned a kind of passenger vehicle is used the bending-type chassis side rail, wherein, is distributed with gate beam in the described longeron frame body.
Further, above-mentioned a kind of passenger vehicle is used the bending-type chassis side rail, and wherein, said assisted fasteners is fastening guide ribs, is distributed with installation through holes on the described fastening guide ribs, and fastening guide ribs is connected with longeron frame body screw.
Further, above-mentioned a kind of passenger vehicle is used the bending-type chassis side rail, and wherein, described external components coupling assembling is rectangular-shaped linking trip.
Again further, above-mentioned a kind of passenger vehicle is used the bending-type chassis side rail, and wherein, the said sinking section outside is provided with the linking assembly.
Adopt technical scheme of the present invention, rely on the sinking section and come-up section that on the longeron frame body, distribute, not only guaranteed car load bending-twisting ability and travel safety, and can reduce floor level, be convenient to passenger getting on/off.Simultaneously, because the existence of these two sections, the wheelbase of vehicle is able to strengthen, and can increase to 3935mm by 3300mm, has improved vehicle ' traveling comfort and stability, and can reduce " braking nose dive " and " starting layback ", has improved resistance to capsizing.In addition, be provided with after the gate beam, whole chassis side rail increases heavily stressed, gradual change rigidity, low noise and other advantages.
The object of the invention, advantage and characteristics will illustrate through the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
Description of drawings
Fig. 1 is the organigram of this passenger vehicle with the bending-type chassis side rail.
The implication of each Reference numeral is following among the figure:
1 longeron frame body, 2 sinking sections
3 come-up sections, 4 rectangular-shaped linking trips
5 gate beams, 6 fastening guide ribs
7 are connected assembly
The specific embodiment
As shown in Figure 1, a kind of passenger vehicle is used the bending-type chassis side rail, includes longeron frame body 1, is characterized in: on longeron frame body 1, be distributed with sinking section 2 and come-up section 3, make longeron frame body 1 constitute the crest shape thus and rise and fall.Simultaneously, be provided with assisted fasteners at the place, initiation region of sinking section 2; End region place at come-up section 3 is provided with the external components coupling assembling.
In conjunction with the present invention's one preferred implementation, be connected with the smooth of other external components for the ease of longeron frame body 1, and guarantee that the levelness after the installation is consistent, the described external components coupling assembling that the present invention adopts is rectangular-shaped linking trip 4.And; The assisted fasteners that the present invention adopts is fastening guide ribs 6; Be distributed with installation through holes on the described fastening guide ribs 6; Fastening guide ribs 6 is connected with longeron frame body 1 screw, can further promote to guarantee car load bending-twisting ability, makes the smooth transition that receives stress that has of sinking section 2.
Simultaneously, consider the whole firmly degree that promotes longeron frame body 1, in longeron frame body 1, be distributed with gate beam 5.Like this, gate beam 5 can withstand on longeron frame body 1 inside, has improved single-piece gradual change rigidity, makes whole longeron frame body 1 can bear vehicle ' and various stress that carrying brought.
Further, in order to let sinking section 2 peripheries can assist the connection vehicle body component, be provided with linking assembly 7 in sinking section 2 outsides.
Through above-mentioned character express and combine accompanying drawing to find out; After adopting the present invention, rely on the sinking section and come-up section that on the longeron frame body, distribute, not only guaranteed car load bending-twisting ability and travel safety; And can reduce floor level, be convenient to passenger getting on/off.Simultaneously, because the existence of these two sections, the wheelbase of vehicle is able to strengthen, and can increase to 3935mm by 3300mm, has improved vehicle ' traveling comfort and stability, and can reduce " braking nose dive " and " starting layback ", has improved resistance to capsizing.In addition, be provided with after the gate beam, whole chassis side rail increases heavily stressed, gradual change rigidity, low noise and other advantages.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.Except that the foregoing description, the present invention can also have other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
