Abstract

A frequency-variable hand rubbed-type motor speed reduction clutch apparatus, and a washing machine. The clutch apparatus includes: an input shaft ( 5 ) connected to a motor rotor ( 1 ); a dehydration shaft ( 18 ); and a clutch apparatus housing ( 8 ) in which the input shaft ( 5 ) and the dehydration shaft ( 18 ) are mounted. A braking wheel ( 12 ) and a braking belt ( 15 ) fitted to the braking wheel ( 12 ) are disposed on the dehydration shaft ( 18 ). A dehydration shaft sleeve ( 20 ) rotating together with the input shaft ( 5 ) is mounted on the input shaft ( 5 ). A clutch shaft sleeve ( 3 ) sliding up and down, and engaging with or separated from the dehydration shaft sleeve ( 20 ) is mounted on the dehydration shaft ( 18 ). The braking belt ( 15 ) and the clutch shaft sleeve ( 3 ) are separately connected to a traction motor ( 11 ) by means of a control apparatus.

First claim

What is claimed is:

1 . A frequency-variable hand rubbed-type motor speed reduction clutch apparatus, comprising:
an input shaft ( 5 ) connected to a motor rotor ( 1 ); a dehydration shaft ( 18 ); and a clutch apparatus housing ( 8 ) in which the input shaft ( 5 ) and the dehydration shaft ( 18 ) are installed, wherein a braking wheel ( 12 ) and a braking belt ( 15 ) fitted to the braking wheel are disposed on the dehydration shaft ( 18 ); wherein a dehydration shaft sleeve ( 20 ) rotating together with the input shaft ( 5 ) is installed on the input shaft ( 5 ), and a clutch shaft sleeve ( 3 ) sliding up and down and engaged with or disengaged from the dehydration shaft sleeve ( 20 ) is installed on the dehydration shaft ( 18 ); wherein the braking belt ( 15 ) and the clutch shaft sleeve ( 3 ) are separately connected to a traction motor ( 11 ) by means of a control apparatus; wherein the traction motor ( 11 ) generates a first displacement, the first displacement is transmitted by means of the control apparatus and drives the braking belt ( 15 ) to move, so that the braking belt ( 15 ) changes from grasping the braking wheel ( 12 ) to loosening the braking wheel ( 12 ), and the dehydration shaft ( 18 ) changes from a braked state to a free rotation state; and wherein the traction motor ( 11 ) generates a second displacement, the second displacement is transmitted by means of the control apparatus and drives the clutch shaft sleeve ( 3 ) to move, so that the clutch shaft sleeve ( 3 ) changes from being disengaged from the dehydration shaft sleeve ( 20 ) to engaged with the dehydration shaft sleeve ( 20 ), and the dehydration shaft ( 18 ) rotates together with the input shaft ( 5 ).

2 . The frequency-variable hand rubbed-type motor speed reduction clutch apparatus according to claim 1 ,
wherein the control apparatus comprises a traction mechanism connected to the traction motor ( 11 ), and a shifting fork mechanism in contact with the clutch shaft sleeve; and wherein a first output end of the traction mechanism is connected to the braking belt ( 15 ), and a second output end of the traction mechanism is connected to the shifting fork mechanism, so as to drive the clutch shaft sleeve ( 3 ) to move up and down.

3 . The frequency-variable hand rubbed-type motor speed reduction clutch apparatus according to claim 2 ,
wherein the traction mechanism comprises a connection arm ( 16 ) and a braking arm ( 17 ); wherein the connection arm ( 16 ) is connected to the traction motor ( 11 ) to transmit control power, and the connection arm ( 16 ) is connected to the braking belt ( 15 ) by means of a first output end of the braking arm ( 17 ); and wherein the connection arm ( 16 ) is connected to the shifting fork mechanism by means of a second output end of the braking arm ( 17 ).

4 .
