Washing machine appliance with dovetail foam damping assembly

A dampening suspension assembly for a washing machine appliance, the washing machine appliance having a cabinet and a tub mounted within the cabinet, the dampening suspension assembly comprising:

• a suspension rod extending along an axial direction between the tub and the cabinet, the suspension rod defining a radial direction perpendicular to the axial direction and a circumferential direction extending around the axial direction;
• and
• a foam damper assembly circumferentially surrounding a portion of the suspension rod, the foam damper assembly comprising a capsule, the capsule comprising a first capsule portion and a second capsule portion releasably interlocked with the first capsule portion by a dovetail joint, the first capsule portion comprising a male dovetail of the dovetail joint and the second capsule portion comprising a female dovetail of the dovetail joint, the foam damper assembly further comprising a first foam friction element disposed in a first trough defined in the first capsule portion of the capsule, and a second foam friction element disposed in a second trough defined in the second capsule portion of the capsule, the second foam friction element opposite the first foam friction element along the radial direction;
• wherein the first foam friction element is compressed between opposing sidewalls of the first trough along the circumferential direction and is compressed against the suspension rod along the radial direction, and wherein the second foam friction element is compressed between opposing sidewalls of the second trough along the circumferential direction and is compressed against the suspension rod along the radial direction.
