The specific embodiment
Contrast accompanying drawing below, the description by embodiment, is described in further detail the specific embodiment of the present invention, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present invention, technical scheme.
Expressed structure of the present invention, is a kind of fore sub frame with collision protection structure as shown in Figure 1, Figure 2, comprises front cross rail 5, after cross member 2, left side beam 1 and the right beam 3.Subframe left side beam 1, rear cross beam of subframe 2, subframe the right beam 3, subframe front cross rail 5, form fore sub frame main body, by being welded to connect, forms the fore sub frame of closed-in construction.
On described left side beam 1 and the right beam 3, revolver suspension arms attachment point 12 and the right suspension arms attachment point 13 of taking turns are set respectively.
On described left side beam 1 and the right beam 3, engine mounting attachment point 10 is all set.
Steering box attachment point 11 is set on described after cross member 2.
Junction at described front cross rail 5 with left side beam 1, the right beam 3, arranges respectively the front attachment point 8 of vehicle body
In described left side beam 1, the rear end of the right beam 3, attachment point 9 after vehicle body is set respectively.
In order to solve the problem of prior art existence and to overcome its defect, realize the collision-deformed goal of the invention of front cross rail that reduces fore sub frame, the technical scheme that the present invention takes is:
As shown in Figure 1 and Figure 2, the fore sub frame with collision protection structure of the present invention, in the place ahead of its front cross rail 5, is provided with the collision prevention girders 6 of horizontal cross; At the two ends of described collision prevention girders 6, left energy-absorption box 4, right energy-absorption box 7 are set respectively, described collision prevention girders 6 is connected with front cross rail 5 by left energy-absorption box 4, right energy-absorption box 7, form complete, with the fore sub frame of energy-absorbing anti-collision girder construction.
The present invention increases the anti-collision beam of a band suction box energy structure at the front end of automobile front subframe, in vehicle traveling process, when the rigid obstacle of car chassis experience road bumps, due to the front portion of collision prevention girders at the bottom of fore sub frame, collision prevention girders directly and road barricade bump, collision prevention girders produces flexural deformation backward, moment of deflection pulls energy-absorption box to curve inwardly, frontal impact power is delivered to energy-absorption box, the wave concavo-convex groove that energy-absorption box arranges, produce crumple, flexural deformation, the enormous impact energy that collision is produced, consumption is between collision prevention girders and energy-absorption box, reduced the collision deformation of front auxiliary car frame front cross beam, strengthened automobile travel handling, safety.
Described collision prevention girders 6 is to be welded after the shaped steel bead docking that is C flute profile of two cross sections, forms the square-section of hollow.Collision prevention girders 6 is to be welded after two C shape grooved parts attach together, the empty square-section of middle formation, and when bumping, energy flexural deformation, bears certain impact force;
Described left energy-absorption box 4, right energy-absorption box 7 are to be all welded after the shaped steel bead docking that is C flute profile of two cross sections, form the square-section of hollow; Longitudinal and the vehicle body vertical consistency of described shaped steel.
Left energy-absorption box 4, right energy-absorption box 7 are to be also welded after being attached together by two C shape grooved parts, and the C shape grooved part of energy-absorption box, is provided with 4 road wave concavo-convex groove.
Described left energy-absorption box 4, right energy-absorption box 7 are equipped with ripple struction 14.
Described ripple struction 14 is perpendicular to described shaped steel multiple tracks wave concavo-convex groove longitudinally.
Wave concavo-convex groove, according to the effect that has guiding distortion, produces crumple distortion when bumping, and accepts bending, the blastic deformation of collision prevention girders distortion, thereby has reduced the distortion of fore sub frame when collision.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
