First, between second sidewall.The bottom plate of rear axle hanger installing plate welds with rear floor skirt beam bottom plate；The second side of rear axle hanger installing plate
The outside of wall is welded with back door threshold beam side, and back door threshold beam opposite side welds with back door threshold beam rear baffle.
Be provided with reinforcing plate before installing plate on front side of rear axle hanger installing plate, before installing plate the top of reinforcing plate be provided with
First flange of rear axle hanger installing plate pan front welding, following be provided with of the preceding reinforcing plate of installing plate are welded with rear floor skirt beam
The second flange connect, reinforcing plate side corresponding with rear axle hanger installing plate the first side wall is provided with extension backward before installing plate
Portion, the extension and rear axle hanger installing plate the first side wall outer surface are welded, before installing plate the opposite side of reinforcing plate be provided with
3rd flange of back door threshold beam welding.
Installing plate external reinforcing plate for car is provided with the outside of rear axle hanger installing plate the first side wall, installing plate external reinforcing plate for car is in platform
It is stepped, including the first vertical section, horizontal segment and the second vertical section, installing plate external reinforcing plate for car passes through the first vertical section and horizontal segment divides
Side wall and bottom plate not with rear floor skirt beam are welded, and installing plate outer reinforcement passes through reinforcing plate before the second vertical section and installing plate
Extension welds.In back door threshold beam rear baffle, back door threshold beam, second sidewall, hind axle assembly, the first side wall, extension and installation
Mounting hole, screw bolt passes back door threshold beam rear baffle, back door threshold beam, are offered in second vertical section of plate external reinforcing plate for car
Two side walls, hind axle assembly, the first side wall, extension and installing plate external reinforcing plate for car the second vertical section on mounting hole and nut lock
Tight fit.
The mounting structure of automobile hind axle of the present invention, bottom plate and the rear floor skirt beam of rear axle hanger installing plate are welded, increased
Firm, the intensity at the bottom plate of rear axle hanger installing plate are added；Rear axle hanger installing plate second sidewall is welded with back door threshold beam, increase
Firm, intensity at rear axle hanger installing plate second sidewall；Outside rear axle hanger installing plate the first side wall and extension and installing plate
Strengthen plate weld, add firm, the intensity at rear axle hanger installing plate the first side wall；Installation is provided with front side of rear axle hanger installing plate
Reinforcing plate before plate, reinforcing plate is welded with its Surrounding Parts before installing plate, and rear axle hanger installing plate side is formed one can be by
The cavity of power, add firm, intensity on front side of rear axle hanger installing plate.The present invention realize rear axle installation with body side rail and
Back door threshold beam links together, and preferably can form an entirety with vehicle body, make its stiffness and strength more preferable.Secondly, the structure
Manufacturing process it is simple, operation it is feasible.
