Problems solved by technology
The existing steering support installation structure is directly positioned by positioning bolts or positioning pins in the Y direction (vehicle width direction). There are many constraints during the adjustment. After the actual assembly, it will be found that the gap between the steering support and the mounting surface of the car body in the Y direction cannot be adjusted. There may be inaccurate positioning in the Y direction, interference with the car body, or lateral movement when the steering support is installed. The problem caused the difference in the gap between the instrument panel and the left and right A-pillars and door trim panels, which affected the installation accuracy of the instrument panel and the interior parts of the center console lamp

Embodiment Construction
[0008] The present invention will be described in further detail below in conjunction with accompanying drawing and embodiment according to figure:
[0009] Such as figure 1 , figure 2 As shown, a steering support installation structure includes a side wall of a vehicle body, a connecting bolt 1 and a connecting bracket 7 arranged on the steering support, and a projection welding nut 8 is arranged on the connecting bracket. The side wall of the car body is composed of a side wall outer skin 2 on the left end face, a side wall reinforcement 4 and a side wall inner skin 5 on the right end face, and an internal thread pipe is fixed between the side wall outer skin 2 and the side wall inner skin 5 3 As the installation hole of the side wall of the vehicle body, the two ends of the internally threaded pipe do not exceed the two end faces of the side wall of the vehicle body and are fixedly connected with the side wall of the vehicle body. An adjustment sleeve 6 is arranged betwe...

The invention discloses an installation structure of a steering support, which comprises a vehicle side body, a connecting bolt and an attachment bracket which is arranged on the steering support, wherein a projection welding nut is arranged on the attachment bracket, and a mounting hole is formed in the vehicle side body. The installation structure of the steering support is characterized in that: internal threads are arranged at the mounting hole of the vehicle side body; a regulating sleeve is arranged between the attachment bracket and the vehicle side body, is provided with external threads and penetrates through the mounting hole of the vehicle side body, one end of the regulating sleeve is connected with the threads of the mounting hole to be used as a regulating end, and the other end of the regulating sleeve extends into the mounting hole of the vehicle side body and is propped against the attachment bracket to be used as a propping end; and the connecting bolt penetrates through the regulating sleeve and is connected with the projection welding nut, and the connecting bolt is in clearance fit with the bore of the regulating sleeve. Because the regulating sleeve is threaded with a rifled pipe in the vehicle side body, the installation structure of the steering support can adjust the extension length of the regulating sleeve, accordingly, the mounting clearance along the Y direction (the vehicle width direction) is compensated, and the accurate location of the Y direction of the steering support and the tolerance accumulated compensation are realized.
Description
technical field [0001] The invention relates to an automobile steering support, in particular to a steering support installation structure. Background technique [0002] The automobile steering support installation structure is to realize the fixed connection between the steering support and the vehicle body. The existing steering support installation structure is directly positioned by positioning bolts or positioning pins in the Y direction (vehicle width direction). There are many constraints during the adjustment. After the actual assembly, it will be found that the gap between the steering support and the mounting surface of the car body in the Y direction cannot be adjusted. There may be inaccurate positioning in the Y direction, interference with the car body, or lateral movement when the steering support is installed. The problem caused the difference in the gap between the instrument panel and the left and right A-pillars and door trim panels, which affected the in...
