Abstract
The invention discloses a front connecting structure of a vehicle frame. The front connecting structure comprises a cross beam (1) and a longitudinal beam (2) connected with the cross beam (1), a reinforcing plate (3) is arranged on a connecting part between the cross beam (1) and the longitudinal beam (2), one side of the reinforcing plate (3) is connected with the cross beam (1), and the other side of the reinforcing plate (3) is connected with the longitudinal beam (2); and the reinforcing plate (3) is provided with a groove (10) used for absorbing energy during collision. By additionally arranging the reinforcing plate on the connecting part between the cross beam and the longitudinal beam, the torsional rigidity of the connecting part between the cross beam and the longitudinal beam can be effectively improved; by additionally arranging the energy-absorbing groove on the reinforcing plate, impact force generated during vehicle collision can be effectively scattered and decreased; and by means of energy-absorbing holes and energy-absorbing grooves on a front plate and a rear plate of the cross beam as well as an outer plate and an inner plate of the longitudinal beam, energy generated during collision can be fully absorbed. The front connecting structure disclosed by the invention has good torsional fatigue resistance and less complex molding process, and is easy to assemble and apply in a real vehicle; and the energy absorbing function of the front side structure is fully considered.
Description
Technical field
The present invention relates to the preceding connection structure of vehicle frame, be specifically related to a kind of crossbeam and longeron connection structure of SUV vehicle frame.
Background technology
Vehicle frame generally is applied in the more large-scale manned vehicle, and the vehicle frame of SUV is connected for suspending with the body contact mode basically, and most load on spring is born by vehicle frame, and vehicle frame is the main load member that connects vehicle body and suspension.Can bear the road surface operating mode of more complicated generally speaking with the manned vehicle of vehicle frame, like cross-country road, distortion road etc., the situation of torsional fatigue failure often appears in vehicle frame under these road surface situation, so the coupling stiffness of crossbeam and longeron and requirement of strength are than higher.But for the collision performance of SUV, vehicle frame has also been played the part of very important role simultaneously.When carrying out front portion or offset collision; The vehicle frame front portion needs certain energy absorption ability; The acceleration/accel of vehicle body when reducing to collide, thus injury reduced for the occupant, at this moment just need vehicle frame can in collision, be easy to generate distortion; Need design special construction simultaneously, and these structure Design will reduce the coupling stiffness and the requirement of strength of vehicle frame greatly with energy-absorbing function.
Summary of the invention
Connection structure before the vehicle frame that the object of the present invention is to provide that a kind of collision performance is good, coupling stiffness and intensity is good.
To achieve these goals, the technical scheme of the present invention's employing is:
Connection structure before the described this vehicle frame, comprise crossbeam, with crossbeam bonded assembly longeron, be provided with brace panel in the junction of said crossbeam and longeron, said brace panel one side be connected with crossbeam, opposite side is connected with longeron.
Said crossbeam by grooved crossbeam header board and crossbeam after plate welding constitute, said longeron is welded with the longeron inner panel by grooved longeron outside plate and constitutes.
Plate welding behind said brace panel one side and the crossbeam, opposite side and the welding of longeron inner panel.
On said brace panel, be provided with the groove that is used for collision energy-absorbing.
Said groove is more than one, and said groove is parallel to be distributed on the said brace panel.
Said crossbeam header board head cross section is greater than afterbody, said crossbeam header board length greater than said crossbeam after plate; Said longeron outside plate head cross section is greater than afterbody, and said longeron outside plate length is greater than said longeron inner panel; Said crossbeam header board head and the welding of said longeron outside plate head.
On plate, longeron outside plate and longeron inner panel behind said crossbeam header board, the crossbeam, be provided with some energy-absorbing grooves.
The invention has the advantages that:, can effectively improve the torsional stiffness of crossbeam and longeron junction through setting up brace panel at crossbeam and longeron junction; Through on said brace panel, setting up the energy-absorbing groove, the effective crumple of impulsive force in the time of can be with vehicle collision; Through on said crossbeam header board, back plate and longeron outside plate, inner panel, setting up the energy-absorbing groove, abundant absorbing impact institute produce power.The antitorque commentaries on classics fatigue property of the present invention is good, has taken into full account the energy-absorbing function of front side structure, and forming process is also uncomplicated, is easy to assembling application in real vehicle.
