Description
Technical field
The invention belongs to cargo vehicle technical fields, in particular, in particular to a kind of cargo vehicle stringer assembly.
Background technique
Currently, cargo vehicle stringer is made of open "u"-shaped groove upward, the top of "u"-shaped groove turns down formation outward and turns over
Side.Existing stringer front end upwarps, and when being collided, cannot efficiently transmit energy from front to back, energy-absorbing effect is bad, no
Conducive to the raising of complete automobile collision passive security performance.
Summary of the invention
Technical problem to be solved by the present invention lies in provide a kind of cargo vehicle stringer assembly that energy-absorbing effect is good.
Technical scheme is as follows: a kind of cargo vehicle stringer assembly, the stringer including " u "-shaped channel-shaped, described vertical
The open upper end of beam turns down in the opposite direction forms the first flange, since stringer is symmetrically set with two on the car body
It is a, therefore in this patent description, with stringer side close to each other be in, the side that is located remotely from each other be it is outer, the stringer from
It include preceding straightway, top rake section, rear-inclined section and rear straightway, the preceding straightway linear cloth along the longitudinal direction after going to
It sets, the rear end of preceding straightway is smoothly connected with the front end of top rake section, outer rear tilted arrangement before the top rake section, before described
The rear end of tilting section and the front end of rear-inclined section are smooth, interior rear outer incline arrangement before the rear-inclined section, the rear-inclined section
Rear end is smoothly connected with the front end of rear straightway, and the rear straightway is linearly arranged along the longitudinal direction, the rear straightway
Rear portion upwarps, and the slot bottom of straightway front, rear-inclined section, top rake section and the preceding straightway afterwards is respectively positioned on same level；
The reinforcer before being fixedly arranged at the front end with of the preceding straightway, the preceding reinforcer are made of the plate body that " u "-shaped is bent, preceding reinforcer
Before opening is fixedly connected on downward above straightway front end；Open court is fixed in the slot of the top rake section and rear-inclined section
On " u "-shaped channel-shaped in reinforcer, the rear end of the interior reinforcer extends to the portion that rear-inclined Duan Yuhou straightway is smoothly connected
Position, there are spacing between bottom in the bottom of the interior reinforcer and the "u"-shaped groove of stringer.
Using the above structure, stringer is arranged to preceding straightway, top rake section, rear-inclined section and rear straightway, and makes rear straight
The rear end of line segment upwarps, and the slot bottom of rear straightway front, rear-inclined section, top rake section and preceding straightway is made to be respectively positioned on same level
Face；And the reinforcer before the front end of preceding straightway is fixed, the fixed interior reinforcer in top rake section and rear-inclined section, to provide
The cargo vehicle stringer assembly that a kind of structure is simple, elasticity is high, energy-absorbing effect is good.When headstock is collided, preceding straightway
Energy can be induced and be absorbed with preceding reinforcer, and energy back kick is passed, top rake section, rear-inclined section and interior reinforcement
The structural elasticity of part composition is high, energy can be fully absorbed, to greatly improve the energy-absorbing effect of stringer.It is real in collision
In testing, improved stringer contribution rate is up to more than ten percent, significantly larger than common stringer.Also, preceding reinforcer also can be used
In lamp door skeleton connection.
The open fold in the opposite direction of the preceding reinforcer forms the second flange, and second flange is corresponding with stringer
The front end of first flange posts and fixes.
To convexing to form vertical reinforcing rib on the outside of " u "-shaped in the middle part of the side plate of the preceding reinforcer, under the reinforcing rib
End extends to corresponding second flange.The structural strength of preceding reinforcer is high, and elasticity is good, is conducive to improve energy-absorbing effect.
The both side plate of the interior reinforcer forms bulge to " u "-shaped inner bulge, on every side plate of interior reinforcer between
Every arrangement, there are three bulges.Elasticity is good for interior reinforcer, is further conducive to improve energy-absorbing effect.
The rear reinforcer of " u "-shaped channel-shaped, the opening of the rear reinforcer are fixed in the rear end of the preceding straightway of the stringer
Fold forms third flange to outside "u"-shaped groove, and the rear reinforcer opening is buckled in the rear end top of straightway before stringer downward, and
And third flange is bonded with the corresponding segment of the first flange of stringer, the low early and high after inclination arrangement of top plate of the rear reinforcer.Afterwards plus
The setting of strong part, on the one hand reinforces the rear end of preceding straightway, is on the other hand convenient on vehicle to front panel and stringer
Between connection reinforced.
The position that straightway slot bottom is connected with top rake section slot bottom transition before the stringer is provided with circular hole, the " u "-shaped
The position adaptability that trench bottom corresponds to circular hole is widened, and the rear end of the rear reinforcer, which extends to, covers circular hole.
The rear end of reinforcer top plate and side plate extends to form the 4th flange to outside "u"-shaped groove after described.
Front wheel housing supplementary angle is fixed on the outside of the rear end of straightway before the stringer, the front wheel housing supplementary angle includes level board
The ontology of shape, the ontology plate face is parallel with the first flange of stringer, and ontology to be formed with before towards bending downward on one side for stringer
The lower flange that straightway lateral wall posts and fixes, the rear end unfilled corner of the ontology, and the back of ontology is folded upward to be formed
Flange afterwards, the front and outside of the ontology bend downward to form flanging.
The slot bottom of straightway raises upward the convex ribs to be formed and be arranged along the longitudinal direction after the stringer, and the convex ribs are after
The rear end of straightway is arranged.
The utility model has the advantages that the present invention is by being arranged to preceding straightway, top rake section, rear-inclined section and rear straightway for stringer,
And the rear end of rear straightway is upwarped, the reinforcer before the front end of preceding straightway is fixed is solid in top rake section and rear-inclined section
Reinforcer in fixed has structure to provide the cargo vehicle stringer assembly that a kind of structure is simple, elasticity is high, energy-absorbing effect is good
Think the features such as ingenious, structure is simple, easy to transform low with improvement cost.
