Abstract
The invention discloses an installation structure of a rear auxiliary frame. The installation structure of the rear auxiliary frame comprises the rear auxiliary frame and a vehicle body longitudinal beam, wherein four corners of the rear auxiliary frame are fixedly installed on the vehicle body longitudinal beam through threaded fasteners, the left corner and the right corner of the front end of the rear auxiliary frame are connected with the vehicle body longitudinal beam respectively through studs, the left corner and the righter corner of the rear end of the rear auxiliary frame are respectively provided with three installation holes, and the two corners of the rear end of the rear auxiliary frame and the vehicle body longitudinal beam are fixed together through six bolts and the installation holes. The installation structure of the rear auxiliary frame can improve the installation positioning accuracy and installation structure strength of the rear auxiliary frame, can effectively bear sideways load, and is convenient to detach, install and repair.
Description
Technical field
The present invention relates to automotive body structure, be specially a kind of mounting structure of Rear secondary frame for vehicle.
Background technology
As shown in Figure 1, four of existing Rear secondary frame for vehicle 1 angles are fixing by threaded fasteners and chassis runner 2.Referring to Fig. 2,3, two jiaos of its front end are connected with the threaded line pipe 11 being welded in chassis runner by bolt 10, and two jiaos of its rear end are enclosed within on the double-screw bolt 12 being welded on chassis runner and use nut 13 fastening.But still there are the following problems for above-mentioned mounting structure: 1,, in two jiaos of attachment points of rear end, double-screw bolt is to be welded and fixed, and can not dismantle inconvenient maintain and replace; 2, in existing structure, the axis of each threaded fasteners is all perpendicular to same plane, and therefore existing mounting structure can not finely bear lateral loading; 3, there are the quality problems such as positioning precision is poor, installation coupling is bad in existing mounting structure.
Summary of the invention
The object of the present invention is to provide a kind of Rear secondary frame for vehicle mounting structure, to improve installation positioning precision and the mounting structure intensity of Rear secondary frame for vehicle, and can effectively bear lateral loading, easy disassembly and maintenance.
Rear secondary frame for vehicle mounting structure of the present invention, comprise Rear secondary frame for vehicle and chassis runner, four angles of this Rear secondary frame for vehicle are installed fixing by threaded fasteners and chassis runner, two jiaos of the left and right of Rear secondary frame for vehicle front end are connected with chassis runner by double end stud respectively, one end of this double end stud spins with the internal thread hole that is welded on the first threaded line pipe in chassis runner, two jiaos of Rear secondary frame for vehicle front ends are enclosed within on this double end stud, and with fastening nuts; In the left and right of Rear secondary frame for vehicle rear end, two jiaos offer respectively three mounting holes, bilateral symmetry at chassis runner is welded with adapter plate, on each piece adapter plate, be respectively provided with a project-welding nut, in the chassis runner near adapter plate both sides, be welded with two the second threaded line pipes, respectively two jiaos of this Rear secondary frame for vehicle rear end are fixed with chassis runner by six bolts and described mounting hole, wherein four bolts spin through the internal thread hole of mounting hole and described the second threaded line pipe, and another two bolts spin through mounting hole and described project-welding nut.
Three mounting holes that left and right, Rear secondary frame for vehicle rear end is two jiaos form leg-of-mutton three summits.
Between the axis inclination of project-welding nut and the axis of the second threaded line pipe, form angle.
On the periphery of double end stud, be provided with circular cone targeting part.
In Rear secondary frame for vehicle mounting structure of the present invention, two jiaos of Rear secondary frame for vehicle front end are inserted in double end stud by circular cone spigot surface, have guaranteed the positioning precision of Rear secondary frame for vehicle, and this double end stud is connected with chassis runner by screw thread, easy disassembly and maintenance.Two jiaos of Rear secondary frame for vehicle rear end are connected with chassis runner by three bolts respectively, three bolt attachment points form constitutionally stable triangular structure, improved mounting structure intensity and assembly quality, and wherein a bolt is and is in tilted layout, and makes this mounting structure can effectively bear lateral loading.
