Embodiment 1

[0045] Such as Figure 2 to Figure 6 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. In the support slideway, the drive motor drives the drive wheel to rotate, the sliding contact surface of the drive end 7 at the tail of the fork lever 3 slides relatively in the support slideway, and the height changes,...

Embodiment 2

[0059] Such as Figure 7 , Figure 8 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 t...

Embodiment 3

[0075] Such as Figure 9 , 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...

Abstract

The invention relates to a deceleration clutch on-off driving device comprising a driving motor, a driving wheel and a shift fork rod. The driving wheel is directly installed on a motor shaft of the driving motor; an axis of the driving wheel is parallel to an axis of the clutch shaft sleeve; the periphery of the driving wheel is provided with a supporting slide way having a height difference in an axial direction; the head part of the shift fork rod is provided with a shift fork controlling up-down movements of the clutch shaft sleeve; the tail part of the shift fork rod is provided with a driving end supported in the slide way; the driving motor drives the driving wheel to rotate, so the driving end on the tail part of the shift fork rod can relatively slide in the supporting slide way and the height of the driving end can change; the height of the shift fork on the head part of the shift fork rod is driven to change; and further the clutch shaft sleeve is driven to move up and down. the deceleration clutch on-off driving device is simply structured and can be easily operated; the driving device has high reliability and small stroke; and the deceleration clutch on-off driving device has compact structure, less space occupation, stable operation and high component integration.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a deceleration clutch driving device. Background technique [0002] The prior art such as the washing machine on the market has a deceleration clutch and a single-phase asynchronous motor installed side by side, driven by a belt pulley and a belt. 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. For example, the patent No. ZL00234747.4 discloses a washing machine deceleration clutch directly driven by a brushless motor. This patent uses a brushless motor to directly drive the clutch of a washing machine, which solves the low efficiency of a single-phase asynchronous motor and improves energy efficiency, but the connection of the motor with this structure is complicated. , can ...
