STRUCTURE OF SUSPENSION MOUNTED ON DIE-CAST SUB-FRAME

摘要

PROBLEM TO BE SOLVED: To prevent excessive input from applying on a sub-frame made of aluminum alloy die-cast by deforming a suspension arm earlier than the sub- frame made of aluminum alloy die-cast, even if excessive input applied is from a road surface to a wheel, for instance. SOLUTION: The sub-frame 10 is made of aluminum alloy die-cast. The strength of the suspension arm 11 is made weaker than the sub-frame 10 made of aluminum alloy die-cast.
