Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 2 and 7, shown preceding sub vehicle frame aluminum alloy installing support locates between preceding sub vehicle frame 1 and cabin boundary beam 2, including the material for the support body 3 of aluminum alloy, support body 3 is the rectangle column cavity body that link up along upper and lower direction, is equipped with X type strengthening rib 7 in the cavity is inside, and this X type strengthening rib 7 has guaranteed support body 3's structural strength along the axial extension of rectangle column cavity body, has improved the rigidity intensity of mounting point.
The edge of the upper end of the support body 3 is provided with a connecting plate 4 extending upwards, the side face of the support body 3 opposite to the connecting plate 4 is fixedly connected with a reinforcing plate 5, and the upper part of the connecting plate 4 and the upper part of the reinforcing plate 5 are fixedly connected with two opposite side faces of the cabin boundary beam 2 respectively. The intersection of the X-shaped reinforcing ribs 7 in the support body 3 is provided with a threaded through hole 6 which is communicated along the vertical direction, and the threaded through hole 6 is coaxially arranged with the second mounting hole 21 on the side beam 2 of the engine room.
The upper part of the connecting plate 4 is provided with a first plug welding hole 41, and the upper part of the reinforcing plate 5 is provided with a second plug welding hole 51 at a position corresponding to the first plug welding hole 41.
The utility model discloses a support structure for the automobile auxiliary frame, including screw through-hole 6, the screw through-hole 6 in-connection has steel wire swivel nut 9, and this steel wire swivel nut 9 hole and connecting bolt screw-thread fit through increasing steel wire swivel nut 9 in screw through-hole 6, the problem that the aluminum alloy screw thread easily became invalid when sub vehicle frame connecting bolt and the installation of aluminum alloy screw through-hole 6 before can preventing adopts steel wire swivel nut 9 to make the screw atress more even simultaneously, the reliability that sub vehicle frame connecting bolt and support body 3 are connected before further increasing.
