Abstract

Suspension units for washing machine bodies incorporate a combination of a spring-damped plunger and tubes lined with conic ended sleeves which dilate proportionally to thrust on the plunger, thus providing a proportional increase in damping friction. Compared with units described in FR1289955, simplified forms of spherical bearing support the base of the unit. The ends of the units are linked by pin and sleeve couplings. An alternative coupling involves a squat tubular rubber bearing incorporating a spring to restore axial alignment after deformation in torsion or shear. The units are light and simple and provide good damping of vibration and noise.
