SUSPENSION CONTROL ARM WITH FRANGIBLE BUSHING COLLAR |
摘要 |
A suspension arm adapted for use in a suspension system of an automotive vehicle including an arm member, a first mounting portion formed at a first end of the arm member and a second mounting portion formed at a second end of the arm member spaced in a first direction relative to the first mounting portion. The first mounting portion including a bushing collar equipped with a frangible portion comprising at least one stress riser, and the longitudinal axis of the collar in the first direction. By adding a frangible feature to the bushing collar of the suspension arm, the breakage mode and breakage timing can be optimized to ensure a tire-and-wheel assembly consistently contacts surrounding parts at the desired time and locations in a predictable sequence and manner during a vehicle impact event. |
