Abstract
A constant damping system includes a damping body having a cap and a stem extending from the cap, a suspension rod accepted through the damping body, a damping fluid provided between the suspension rod and the stem of the damping body, the damping fluid configured to provide a constant damping force between the suspension rod and the stem, wherein the damping fluid is one of a hydro-carbon base or a silicon base, and an axial spring having a first end attached to the suspension rod and a second end contacting the cap of the damping body.
Claims20
A constant damping system defining an axial direction, a radial direction, and a circumferential direction, the constant damping system comprising:
- a damping body comprising a cap and a stem extending from the cap along the axial direction;
- a suspension rod accepted through the damping body along the axial direction;
- a damping fluid provided between the suspension rod and the stem of the damping body, the damping fluid configured to provide a constant damping force between the suspension rod and the stem, wherein the damping fluid is one of a hydro-carbon base or a silicon base;
- and
- an axial spring having a first end attached to the suspension rod and a second end contacting the cap of the damping body.
A laundry treatment appliance, comprising:
- a cabinet;
- a tub provided within the cabinet;
- and
- a constant damping system that connects the tub to the cabinet, the constant damping system defining an axial direction, a radial direction, and a circumferential direction, wherein the constant damping system comprises:
- a damping body comprising a cap and a stem extending from the cap along the axial direction;
- a suspension rod accepted through the damping body along the axial direction;
- a damping fluid provided between the suspension rod and the stem of the damping body, the damping fluid configured to provide a constant damping force between the suspension rod and the stem, wherein the damping fluid is one of a hydro-carbon base or a silicon base;
- and
- a spring having a first end attached to the suspension rod and a second end contacting the cap of the damping body.
A constant damping system defining an axial direction, a radial direction, and a circumferential direction, the constant damping system comprising:
- a damping body, the damping body comprising:
- a cap;
- and
- a collet extending from the cap along the axial direction, the collet comprising a plurality of segments extending along the axial direction and spaced apart along the circumferential direction;
- a suspension rod accepted through the damping body along the axial direction;
- a damping fluid provided between the suspension rod and the stem of the damping body, the damping fluid configured to provide a constant damping force between the suspension rod and the stem, wherein the damping fluid is one of a hydro-carbon base or a silicon base;
- a spring clamp provided circumferentially around the collet, the spring clamp providing a constant radial force to the collet and the suspension rod;
- and
- an axial spring having a first end attached to the suspension rod and a second end contacting the cap of the damping body.
