Problems solved by technology

The cage is therefore a very relevant component, but has not been significantly improved to allow simpler assembly steps of the friction rings inside the cage and to use the same cage for dampers intended to support different loads, and therefore require friction rings or strips of different sizes

Embodiment Construction

[0019] refer to Figure 4 , the cage (1) according to the invention is configured to house friction rings inside it (in Figure 4 not shown). It is roughly cylindrical in shape and hollow inside so that it can slideably accommodate the piston (4) on which is shown the closing plug of the housing also mounted with the spring limit stop (2) and the damper (3).

[0020] In addition, the cage is constructed such that the piston can protrude from two parts relative to the cage, as it does for example in Figure 4 shown in , to enable mounting of the spring limit stop (2) around the piston, from both parts of the cage. In this way, the cage is movable relative to the piston (4) and relative to the closing plug (3). In addition, the cage can also be relative to the housing of the damper ( Figure 4 not shown) movement.

[0021] Since the limit stops (2) limit the possibility of sliding of the cage (1) relative to the housing, their placement allows to define the range of motion...

Abstract

Cage (1) configured to house thereinside a friction ring to be used in friction dampers for washing machines, characterized in thatit comprises a first (11) and a second piece (12) configured to be coupled by introducing the one in the other one.

Description

technical field [0001] The invention relates to a cage for friction rings used in friction dampers for washing machines. [0002] It is known to use friction dampers in washing machines that are bound to the drum and frame of the washing machine to reduce the noise and vibrations generated by the centrifugal action of the electric washing machine. [0003] All known embodiments comprise a housing or housing, substantially tubular in shape, open at the ends, within which housing the piston slides and one or more friction rings integrally mounted to the cage. A cage is introduced into the housing and is axially slidable relative to the housing between a first position and a second position determined by suitable limit stops, and the piston is introduced into the cage. A plug mounted at the open end of the housing acts as a limiting stop for the cage and prevents the cage from coming off the housing. The housing and the piston are constrained to the two elements (the frame and ...
