Claims2
A structure for fixing a lower suspension arm bracket, comprising:
- a sleeve with upper and lower ends, said sleeve upper and lower ends being joined with a gusset plate and a lower side member by welds, said sleeve defining a fixing hole including a female threaded portion, a tapered intermediate portion and a non-threaded hole portion;
- a bolt engaging said fixing hole and engaging said lower arm suspension bracket to fix said lower arm suspension bracket to said lower side member, said bolt including a male threaded portion, an intermediate tapered portion and a stem portion, said male threaded portion being dimensioned to engage said female threaded portion of said fixing hole, said tapered portion being dimensioned to engage said fixing hole intermediate tapered portion and said stem portion having a diameter which is substantially the same as a diameter of said fixing hole such that said stem portion engages said fixing hole.
A structure for fixing a lower suspension arm bracket, comprising:
- a sleeve having upper and lower ends joined with a gusset plate and a lower side member by welds;
- and connection means including a fixing hole formed in said sleeve and a bolt engaging said sleeve and said fixing hole and engaging the lower suspension arm bracket to fix said lower suspension arm bracket to said lower side member, said fixing hole being formed in said sleeve to define a female threaded portion, a tapered portion and a non tapered hole portion, said bolt including a male threaded portion dimensioned for engaging said female threaded portion, a tapered portion dimensioned to engage said fixing hole tapered portion and a stem portion having a diameter substantially the same as a diameter of said non threaded portion such that a surface of said stem portion engages a surface of said non threaded portion for preventing sagging of said bolt relative to said fixing hole to prevent a change in alignment of said lower suspension arm bracket.
