  • Washing machine having improved out-of-balance performance
    Patent number: 5117658
    Abstract: A washing machine having a mid-level pivot and traverse suspension system. The washing machine includes a tub assembly disposed over a support, with the assembly having a center of mass disposed at approximately the same axial position as the typical out-of-balance load. The pivoting force is a function of the distance between the center of mass of the tub assembly and the out-of-balance load. Thus, the pivoting forces are reduced, as well as the corresponding reaction forces transferred to the floor.
