Abstract
The invention relates to a mounting structure for an automobile auxiliary frame at the front section of an engine cabin boundary beam. The mounting structure comprises the front section of the engine cabin boundary beam, an auxiliary frame mounting screwed pipe, an auxiliary frame mounting nut plate and a screwed pipe reinforcing plate. The three components of the auxiliary frame mounting screwed pipe, the auxiliary frame mounting nut plate and the screwed pipe reinforcing plate are mutually connected to form corners mutually, and are welded in reinforcing pieces together, and a reinforcing effect is formed in the X, Y and Z directions of the car body, so that the torsion of the mounting surface of an auxiliary frame during the running of the whole vehicle can be prevented, and torsion attenuation of mounting bolts of the auxiliary frame is prevented. Under the precondition that the function of structure installation is guaranteed, the mounting structure further has high strength value and high rigidity value of mounting point that a general structure cannot achieve.

Between leading portion.
The subframe vehicle body that can be seen that this front-engine rear-drive vehicle provided by the present invention from above structure installs knot
Structure, is mainly made up of following part: one, engine nacelle curb girder front part, and this part is as the important portion in body structural member
Point, body structure plays the effect connecting and carrying each part, present configuration mainly plays carrying effect；2nd, send out
Motivation cabin curb girder front part reinforcement, this part mainly plays booster action to mount point structure in present configuration；3rd, subframe
Corrugated tubing is installed, this part is tubular nut flanged disk, this nut performance rate value is high, high torsion can be born it is ensured that pair
Vehicle frame mount point intensity and toughness；4th, subframe installs nutplate, and this part mainly carries subframe in the present invention and installs spiral shell
The effect of the welding procedure feasibility of stricture of vagina pipe；5th, corrugated tubing reinforcing plate, this part installs corrugated tubing in z to carrying out to subframe
Strengthen, and ensure this corrugated tubing perpendicularity.
The subframe mount structure of this front-engine rear-drive vehicle provided by the present invention ensure that structure installation function
Under the premise of, also there is general structure inaccessiable mount point intensity values and high rigidity value, this structure can meet subframe peace
Decorate the performance issues such as the decay of stud torsion, the mount point insufficient rigidity of easy appearance.
