Abstract
The utility model relates to a suspension system of a washing machine, which belongs to the mechanical technical field of a washing machine and comprises a hanger rod, a spring, a spring seat, a shim, an upper ball seat, a lower ball seat, a buffer sleeve, an outer cover of the buffer sleeve and a sleeve pipe, wherein the upper end of the hanger rod is connected with a box body of the washing machine through the upper ball seat, and the lower end is connected with a washing drum through the lower ball seat; an inner hole of the buffer sleeve and the hanger rod are in interference fit, and an outer circle forms a wedge shape; the whole buffer sleeve is clamped between the lower ball seat and the outer cover of the buffer sleeve, the spring is arranged between the outer cover of the buffer sleeve and the spring seat, and the sleeve pipe is sheathed with the outer circle of the spring in an interference fit mode.
Description
Technical field
The utility model relates to a kind of part of washing machine, specifically a kind of washing machine suspension system.Belong to the washing machine field of mechanical technique.
Background technology
What traditional suspension (Fig. 1) adopted is telescopic, the damping force of this structure mainly comes from spring and air damping, but because the long-term friction between spring housing and the rubber spring seat, not only can produce noise, and cause the wearing and tearing of spring base, and use sealing effectiveness of a specified duration more poor more, air damping power can reduce gradually, vibration, the noise of washing machine are increased, be difficult to satisfy customer requirements.Therefore, it is just necessary to invent a kind of novel suspension that can vibration and noise reducing.
Summary of the invention
The purpose of this utility model is to provide the suspension that a kind of noise is low, vibration is little, to improve the overall performance of washing machine, reaches gratifying clean result.
The utility model washing machine suspension arrangement takes following technical scheme to realize:
The washing machine suspension arrangement comprises suspension rod, spring and spring base, it is characterized in that it also comprises pad, upper ball base, lower ball base, cushion collar, cushion collar outer cover and sleeve pipe; Described suspension rod upper end links to each other with casing of washing machine by upper ball base, and the lower end links to each other with wash bucket by lower ball base; Interference fit between described cushion collar endoporus and the suspension rod, cylindrical are wedge shape, and whole cushion collar is stuck between lower ball base and the cushion collar outer cover; Spring is installed between cushion collar outer cover and the spring base, and sleeve pipe is placed in the spring outer ring in the mode of interference fit.
Aforesaid washing machine suspension arrangement is characterized in that scribbling damping grease in the wherein said cushion collar.
Operation principle of the present utility model is: its upper end of suspension rod links to each other with casing of washing machine by upper ball base, and the lower end links to each other with wash bucket by lower ball base, is suspended in the casing to guarantee wash bucket.Cushion collar adopts flexible elastomeric material, interference fit between endoporus and the suspension rod; Cylindrical is a wedge shape, and whole cushion collar is stuck between lower ball base and the cushion collar outer cover, scribbles the higher damping grease of viscosity in the cushion collar, and purpose is the wearing and tearing that increase damping and reduce cushion collar; When producing relative slips between cushion collar and suspension rod, because interference fit effect meeting produces damping force, because cushion collar is a wedge shape, the pressure that is subjected to continuous variation when lower ball base is done the time spent simultaneously, and damping force also can change accordingly.Spring is installed between cushion collar outer cover and the spring base, can obtain constant damping force, has the absorbing effect.Sleeve pipe is placed in the spring outer ring in the mode of interference fit, has the effect to the guiding and the buffering of spring.
This device uses cushion collar and damping grease to replace air damping, has structurally avoided owing to wearing and tearing produce the phenomenon that damping force reduces, and is durable in use, obtained the effect of vibration and noise reducing.It is supported on the wash bucket of rotary drum washing machine in the casing with suspension status.In the washing machine course of work, the spring in the suspension and the damping force of cushion collar can play the vibration and noise reducing effect to greatest extent.This apparatus structure is simple, and effect is remarkable.
Description of drawings
Fig. 1 is traditional telescopic suspension structure schematic diagram.Wherein hang pin (10); Suspension rod (3); Spring housing (11); Spring (7); Spring base (9); Tensioning spring (12).
Fig. 2 is the utility model washing machine suspension arrangement structural representation.
Fig. 3 is the utility model washing machine suspension arrangement cushion collar partial enlarged drawing.
Fig. 4 is washing machine suspension arrangement medi-spring and sleeve pipe partial enlarged drawing.
The specific embodiment:
As Fig. 2--the utility model washing machine suspension arrangement shown in 4, its Intermediate gasket (1), upper ball base (2), suspension rod (3), lower ball base (4), cushion collar (5), cushion collar outer cover (6), spring (7), sleeve pipe (8) and spring base (9); Its upper end of suspension rod (3) links to each other with casing of washing machine by upper ball base (2), and the lower end links to each other with wash bucket by lower ball base (4), is suspended in the casing to guarantee wash bucket.Cushion collar (5) adopts flexible elastomeric material, interference fit between endoporus and the suspension rod (3); Cylindrical is a wedge shape, and whole cushion collar (5) is stuck between lower ball base (4) and cushion collar (5) outer cover, scribbles the higher damping grease of viscosity in the cushion collar (5), and purpose is the wearing and tearing that increase damping and reduce cushion collar (5); When producing relative slips between cushion collar (5) and suspension rod (3), because interference fit effect meeting produces damping force, because cushion collar is a wedge shape, the pressure that is subjected to continuous variation when lower ball base (4) is done the time spent simultaneously, and damping force also can change accordingly.Spring (7) is installed between cushion collar outer cover (6) and the spring base (9), can obtain constant damping force, has the absorbing effect.Sleeve pipe is placed in the spring outer ring in the mode of interference fit, has the effect to the guiding and the buffering of spring.When load is applied on the lower ball base (4), under the effect of spring (7), cushion collar outer cover (6) causes cushion collar (5) to produce distortion with the stressed clamping of lower ball base and clamps suspension rod, frictional force when load increases on the cushion collar also increases thereupon, damping grease between cushion collar and the lower ball base has guaranteed that cushion collar is not worn in the long-term course of work, also played simultaneously the effect that increases damping force, sleeve pipe (8) has played guiding and cushioning effect to spring (7), thereby the assurance whole system is normally moved.
The foregoing description does not limit the utility model in any form, and all technical schemes of taking to be equal to replacement or equivalent transformation that form obtained all drop within the protection domain of the present utility model.
Claims (2)
1, washing machine suspension arrangement comprises suspension rod, spring and spring base, it is characterized in that it also comprises pad, upper ball base, lower ball base, cushion collar, cushion collar outer cover and sleeve pipe; Described suspension rod upper end links to each other with casing of washing machine by upper ball base, and the lower end links to each other with wash bucket by lower ball base; Interference fit between described cushion collar endoporus and the suspension rod, cylindrical are wedge shape, and whole cushion collar is stuck between lower ball base and the cushion collar outer cover; Spring is installed between cushion collar outer cover and the spring base, and sleeve pipe is placed in the spring outer ring in the mode of interference fit.
