Problems solved by technology

In the prior art, the driving motor is mostly used to pull one end of the shift fork through a rope, and the other end controls the clutch bushing or the clutch slider to move up and down. However, the above method of controlling the up and down movement of the clutch bushing has low accuracy and high failure rate. And take up a lot of space
[0005] At the same time, the driving motor of the existing clutch device is generally installed on the mounting plate of the deceleration clutch, which makes the driving device of the deceleration clutch need a longer stroke distance, makes the axial distance of the deceleration clutch larger, occupies a lot of space inside the washing machine, and causes the washing machine The washing capacity is reduced

Embodiment 1

[0043] like Figure 3 to Figure 7 as shown in Figure 2-5 As shown, a deceleration clutch clutch driving device described in this embodiment includes a driving motor 1, a driving wheel 2 and a shift fork lever 3, the driving wheel 1 is installed on the output shaft of the driving motor 1, and the circumference of the driving wheel 2 is provided with supports The supporting surface has a height difference in the axial direction. The fork lever 3 is a lever structure with a fixed fulcrum in the middle. The head of the fork lever 3 is a shift fork 6. The shift fork 6 is located below the clutch bushing 14, and the The spring controls the up and down movement of the clutch sleeve 14 together. The tail of the shift fork lever 3 is the driving end 7, and the driving end 7 is provided with a sliding contact surface, which is slidingly matched with the supporting surface; the driving motor 1 drives the driving wheel 2 to rotate, and the tail of the shift fork lever The driving end 7 ...

Embodiment 2

[0059] like Image 6 , Figure 8 and Figure 9 As shown, in this embodiment, the upper and lower ends of the clutch sleeve 14 are respectively provided with upper spline teeth 48 meshing with the upper fixed disk and lower spline teeth 49 meshing with the lower dehydration disk. For ease of description, the direction in which the clutch sleeve rotates with the motor rotor 17 is defined as clockwise. The tooth top profile of the upper spline tooth 48 is a slope rising in the clockwise direction; the tooth top profile of the lower spline tooth 49 is a slope descending clockwise. Thus, the clutch sleeve 14 is more smoothly and smoothly meshed when the upper spline teeth 48 and the upper mating spline teeth 50 and the lower spline teeth 49 and the lower mating spline teeth 51 mesh.

[0060] In this embodiment, the lower dehydration tray is composed of a part that is separately set on the top surface of the rotor 17 of the motor or is integrally set with the rotor 17, and the up...

Embodiment 3

[0068] like Figure 8 and Figure 9 As shown, in this embodiment, a clutch bushing, the upper and lower ends of the clutch bushing 14 are respectively provided with upper spline teeth 48 meshing with the upper fixed disk and lower spline teeth 49 meshing with the lower dehydration disk. , At least one of the meshing parts of the upper and lower teeth is provided with a shock-absorbing layer.

[0069] In this embodiment, the shock-absorbing layer is composed of a shock-absorbing sleeve 34 sleeved on the outer wall of the clutch shaft sleeve 14 . The shock absorbing sleeve 34 protrudes from the tooth groove bottom of the lower spline teeth and / or the upper spline teeth, and the shock absorbing sleeve 34 is made of elastic material; preferably, the shock absorbing sleeve 34 is made of It is composed of rubber sleeves that are elastically stretchable and deformable.

[0070] In this embodiment, due to the process of tooth engagement between the clutch sleeve 14 and the lower de...

Abstract

The invention relates to a clutch driving device of a washing machine, in particular to a clutch drive installing structure of a speed reducing clutch. The clutch driving device comprises a driving motor, a driving wheel and a shifting fork, wherein the driving wheel is installed on a driving motor shaft, and the driving motor is fixedly installed on a housing of the speed reducing clutch. The clutch driving device formed by the driving motor, and the driving wheel and the shifting fork is fixedly installed on the housing of the speed reducing clutch through an installing cover, so that the clutch driving device is fixed and installed with the speed reducing clutch and other parts without an installing plate, and the production efficiency of the washing machine is improved. In addition, the clutch driving device drives the shifting fork by adopting the driving wheel, the length of the shifting fork is decreased, the overall structure of the speed reducing clutch is more compact, and occupied space is decreased.

Description

technical field [0001] The invention relates to a deceleration clutch in the field of washing machines, in particular to a clutch driving device. Background technique [0002] The deceleration clutch and the single-phase asynchronous motor of the existing washing machine are installed side by side, and are driven by pulleys and belts. This type of deceleration clutch has low efficiency, high noise, poor practicability, and a high failure rate of the transmission part. Therefore, relevant technical personnel have proposed a technical scheme in which the motor and the clutch are coaxial. [0003] For example, the Chinese patent with application number CN201120257375.8 is a bionic hand-rubbing frequency conversion deceleration clutch for washing machines, which includes a matching lower housing and an input shaft, the lower housing is equipped with a DC brushless motor stator, and the end of the input shaft is connected There is an outer rotor of a brushless DC motor, the stat...
