Suspension arm for connecting wheel to body of car, has element made of light material and molded onto base element made of forged steel, where molded element replaces locations subjected to lower stresses during physical operation of arm

摘要

The arm (1) has a base element (2) made of forged steel, and another element (3) made of a light material and molded onto the base element. The base element is designed according to a model of the distribution of physical constraints in the suspension arm during operation, where the molded element replaces the locations subjected to lower stresses during physical operation. Fixing points (E1, E2) for fixing the arm to a body of a car are located close to a bent part of the arm and an end of the arm, and a fixing point (D) for support of a wheel is located at the other end of the arm.
