  • Reinforced hollow upper control arm for vehicle suspension system
    Patent number: 5338056
    Abstract: An upper control arm for a vehicle suspension system having a modulus section of hollow construction for reduced weight. The modulus section of the control arm is of a stamped and welded construction thereby eliminating material weight while reducing the cost of manufacturing. The modulus section has a substantially triangular configuration with a reinforced rim flange along the high compression stress area of the control arm elbow. The reinforced rim flange improves the strength of the control arm without sacrificing the weight reduction provided by the hollow construction.
    Type: Grant
    Filed: March 16, 1993
    Date of Patent: August 16, 1994
    Assignee: MascoTech, Inc.

  • Process of manufacturing hollow triangular upper control arm
    Patent number: 5163603
    Abstract: An upper control arm for a vehicle suspension system having a modulus section of hollow construction for reduced weight. The modulus section of the control arm is of a stamped and welded construction thereby eliminating material weight while reducing the cost of manufacturing. The modulus section has a substantially triangular configuration with a reinforced rim flange along the high compression stress area of the control arm elbow. The reinforced rim flange improves the strength of the control arm without sacrificing the weight reduction provided by the hollow construction. A series of apertures are formed in the control arm to reduce weight and improve the harmonic resonancy of the control arm.
