Abstract
A suspension system for an automatic washing machine wherein multiple independent modes of motion are provided, and the springs biasing the respective modes are selected so that the critical frequencies (i.e. maximum excursions) of the modes do not occur simultaneously. For example, a first set of centering springs biases a traversing motion and a second set of upstanding springs biases a pivoting motion. The spring rates are selected so that as the spin tub accelerates, the maximum excursion of one of the modes occurs first followed by the maximum excursion of the other mode at a higher spin tub speed.
