  • the vertical upper portion 73 of the outrigger upper portion 71 is in contact with the inner leg portion 92 of the bracket 16 from the inside in the vehicle width direction.
  • the front vertical flange 65 of the cross member 18 is in contact with the vertical upper portion 73 from the inside in the vehicle width direction.
  • the front vertical flange 65, the vertical upper portion 73 and the inner leg portion 92 are joined by spot welding or the like in a state where they are overlapped. That is, the left end 18 a of the cross member 18 is coupled to the bracket 16 via the outrigger upper portion 71.
  • the input impact load F1 can be efficiently transmitted to the cross member 18 through the outrigger upper portion 71 and the bracket 16.
  • the cross member 18 can support the impact load F1 from the side of the vehicle body.
  • the left end 18 a of the cross member 18 is coupled to the bracket 16 via the outrigger upper portion 71.
  • the outrigger upper portion 71 is reinforced by the cross member 18 and the bracket 16. Thereby, the rigidity of the outrigger upper part 71 (that is, the rear part of the vehicle body of the vehicle 10) can be secured.
  • FIG. 10 the frame structure 100 of the vehicle has a plurality of bead portions 105 formed on the bracket 102, and the other configuration is the same as that of the first embodiment.
  • the bracket 102 has a plurality of bead portions 105 formed on the top portion 103. Similar to the bead portion 75 of the first embodiment, the plurality of bead portions 105 are disposed at an interval in the longitudinal direction of the vehicle body, and extend linearly in the vehicle width direction. The bead portion 105 is expanded from the top portion 103 of the bracket 102 toward the horizontal upper portion 72. With the bead portion 105 in contact with the horizontal upper portion 72, the bead portion 105 is coupled to the horizontal upper portion 72 by spot welding or the like.
  • the same effect as that of the first embodiment can be obtained. That is, by connecting the bead portion 105 of the top portion 103 to the horizontal upper portion 72, the frame 70 is reinforced by the bracket 102. Thus, the rigidity of the frame 70 is enhanced. Thereby, when the impact load F1 is input to the side sill 12 from the side of the vehicle body due to the side collision, the deformation of the frame 70 due to the impact load F1 is suppressed. Further, by reinforcing the frame 70 with the bracket 102, the rigidity of the frame 70 can be enhanced without using a separate member such as a reinforcing member. Thereby, weight reduction and cost reduction of the frame structure 100 of a vehicle can be achieved.
  • the top portion 103 can be coupled to the horizontal upper portion 72 by the bead portion 105. Accordingly, it is not necessary to increase the positional accuracy of the horizontal upper portion 72 and the top portion 103 more than necessary, and the productivity of the vehicle frame structure 100 can be improved.
  • the swinging shaft portion 84 of the trailing arm 85 is illustrated as an on-vehicle component, but the invention is not limited thereto. It is also possible to use the on-vehicle component as another member such as a silencer or a canister.
  • the present invention is not limited to this. .
  • the number of the bead portions 75 of the first embodiment and the bead portions 105 of the second embodiment can be changed as appropriate.
  • the first nut 78 is fixed to the inner leg 92 and the second nut 79 is fixed to the outer leg 93.

Abstract

L'invention concerne une structure de châssis de véhicule comportant un châssis et un support (16) fixé au châssis. Le châssis comporte une partie supérieure de stabilisateur (71), une partie arrière (31) d'un élément interne (22), un stabilisateur (14) et une paroi externe (37) d'un châssis latéral arrière (13). Une partie d'arbre pivotant d'un bras oscillant est soutenue par le support (16). Une pluralité de parties de talon (75) est formée dans la partie supérieure de stabilisateur (71). Les parties de talon (75) sont étendues vers l'extérieur à partir de la partie supérieure de stabilisateur (71) jusqu'à la partie de crête (95) du support (16) et sont jointes à la partie de crête (95).
