The good complement of chassis intensity.
Preferably, support rod is straight tube.The axially loaded intensity of straight tube is best.
Preferably, support rod is hollow straight tube.Under the premise of ensuring intensity, support rod be it is hollow, facilitate
Body lightening.
Strengthen muscle preferably, being equipped in support rod, the length direction for strengthening muscle along support rod extends.Strengthening muscle can be
Further strengthen support rod in axial direction.
Preferably, the cross sectional shape of the support rod is rectangle；Mating surface is horizontal plane, support under the rear end of subframe
The upper surface of bar front end and the mating surface of subframe rear end are fixed；Mating surface is horizontal plane on the front end of sill strip, after support rod
The lower end surface at end and the mating surface of sill strip front end are fixed.Pass through support rod cross sectional shape, subframe rear end mating surface, sill strip
The design of front end mating surface can make the combination of connector two-by-two closer.
Preferably, the upper surface of support rod front end is equipped with riveting through holes, it is corresponding in mating surface under the rear end of subframe
Position is equipped with riveting through holes, is riveted after the riveting through holes that rivet penetrates through on support rod front end and subframe simultaneously, rivets it
Support rod front end, rivet, subframe three are fixed by welding afterwards；The lower end surface of rod rear end is supported to be equipped with riveting through holes,
Corresponding position is equipped with riveting through holes in mating surface on the front end of sill strip, and rivet is penetrated through simultaneously on support rod rear end and sill strip
It is riveted after riveting through holes, is fixed support rod rear end, rivet, sill strip three by welding after riveting.This programme is set
Meter realizes fixation by the way of rivet welding, it is ensured that bonding strength.
Preferably, the riveting through holes of support rod front-end and back-end are no less than 2.Such design can mention as far as possible
High bonding strength.
In conclusion showing the beneficial effects of the present invention are: can effectively conduct front part of vehicle stress to rear of vehicle
It writes and mitigates front wall intrusion volume, play a protective role to driver and passenger and vehicle.
