Specifically, hanger bar 1 defines one axially.
Lower carriage 2 is connected with (i.e. indicated under arrow as shown in Figure 1 direction) end under hanger bar 1.
Elastic component 3 be socketed in hanger bar 1 and elastic component 3 lower end against lower carriage 2.For example, elastic component 3 can be bullet
Spring.
Upper bracket 4, the upper bracket 4 have compression face for contacting with bucket outer wall face, and the upper bracket 4 is movably
Be located in the hanger bar 1 and the elastic component 3 upper end against the upper bracket 4.
Explanation is needed exist for, common washing machine includes casing and the staving being located in casing.According to of the invention real
When applying the suspension dampening assembly for washing machine of example and being installed on washing machine, lower carriage 2 is connected with casing and upper bracket 4 and bucket
Body phase connects.When washing machine runs, as the rotation of staving can produce vibrations, and it is according to embodiments of the present invention for washing machine
Suspension dampening assembly, with elastic component and the upper bracket being movably arranged in hanger bar, the upper bracket is provided with and institute
The through hole that hanger bar is adapted is stated, the relatively described axial direction of through hole of the upper bracket has two relatively inclined internal faces 41, uses
At least partly contact to produce friction to offset washing machine fortune with the corresponding outside wall surface 11 with hanger bar after the pressure by staving
Produced shaking force during row.
The according to embodiments of the present invention suspension dampening assembly for washing machine, as shown in Fig. 2 the upper bracket 4 is received
Pressure surface 42 is spherical.
An example of the invention, as shown in Fig. 2 upper bracket 4 is provided with the through hole 41 being adapted with hanger bar 1,
Hanger bar 1 is through through hole 41 so that upper bracket 4 is socketed in hanger bar 1.Further, the diameter of through hole 41 is not more than hanger bar
1 external diameter, for example, the diameter of through hole 41 can be slightly less than the external diameter of hanger bar 1.Thus, it is possible to make upper bracket 4 and hanger bar 1
Cooperation it is more tight, it is easier to when upper bracket 4 is moved in hanger bar 1, produce damping friction between the two, offset staving shake
The effect of power is more preferable.
Advantageously, lower carriage 2 and upper bracket 4 can be plastic stent.Further, lower carriage 2 and upper bracket 4 by
