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 clutch drive device of the existing deceleration clutch is generally high, so that the clutch drive device of the deceleration clutch needs a longer stroke distance, making the axial distance of the deceleration clutch larger, occupying a lot of space inside the washing machine, resulting in a reduction in the washing capacity of the washing machine

Embodiment 1

[0047] like 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 motor 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 slides relatively on the support sur...

Embodiment 2

[0065] like Image 6 , Figure 7 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, and the driving wheel 2 is directly installed on the motor shaft of the driving motor 1, and the axis of the driving wheel 2 Parallel to the axis of the clutch bushing 14, there is a supporting slideway on the circumference of the driving wheel 2. The supporting slideway has a height difference in the axial direction. The shift fork lever 3 is a lever structure with a fixed fulcrum in the middle. It is a shift fork 6, and the shift fork 6 is located below the clutch bushing 14, and controls the up and down movement of the clutch bushing 14 together with the return spring. Inside the support slideway, the drive motor

[0066] Drive the driving wheel to rotate, the sliding contact surface of the driving end 7 at the tail of the fork lever 3 slides relatively in the support slideway, and the h...

Embodiment 3

[0080] like Figure 8 to Figure 10 As shown, a deceleration clutch clutch driving device described in this embodiment includes a drive motor 1, a drive wheel 2 and a shift fork lever 3. The shift fork lever 3 is a lever structure, and the middle part is provided with a fixed fulcrum. The shift fork lever 3 The head is a shift fork 6, and the shift fork 6 is located below the clutch bushing 14, and controls the up and down movement of the clutch bushing 14 together with the return spring. Perpendicular to the axis of the clutch bushing 14, the drive wheel 2 is a cam structure, and the circumference of the cam 26 gradually changes radially. The tail of the shift fork is supported on the circumference of the cam, and the driving motor drives the cam to rotate. The tail of the shift fork rod has a different radius from the cam. Circumferential contact, height change, drive shift fork head shift fork height change, head shift fork 6 and back-moving spring work together to drive clu...

Abstract

The invention relates to a clutch drive device of a washing machine. The clutch drive device comprises a driving motor, a driving wheel and a shifting fork rod. The driving wheel comprises a support surface having a height difference. One end of the shifting fork rod is supported on the support surface of the driving wheel and the other end of the shifting fork rod is in limit contact with a clutch shaft sleeve. The driving wheel controls the shifting fork rod to move to drive the clutch shaft sleeve to move vertically while rotating along with a driving motor shaft. The driving wheel is installed on the driving motor shaft and the driving motor is fixedly installed on an installing plate of a deceleration clutch. A shifting fork driving the clutch shaft sleeve of a deceleration clutch is driven by a cam, so that the overall height of the deceleration clutch is reduced and the deceleration clutch occupies less internal space of a washing machine.

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...
