For the ease of understanding the utility model embodiment, below to the clutch of the utility model one of which embodiment offer
The operation principle of mechanism illustrates：
1. during initial position：Driving lever 6 is located at installation site, ring wedge-shaped protrusion plane 704 and ring support wedge-shaped protrusion
Plane 208 overlaps, and positioned at upper, support clutch axle sleeve 5 engages ring 7 with the first fluted disc 3；Input axle sleeve 12 can not rotate, with
12 relatively-stationary interior bucket of input axle sleeve is locked；Clutch stage clip 26 is in compressive state, and now washing machine is in washing state.
2. when washing machine sends dehydration instruction：Driving lever 6 turns over certain angle α, band under driver effect around pivot pin 22
Action-oriented pin 701 slides in arcuate socket 601, and guide finger 701 drives ring 7 to turn over corresponding angle beta in ring support 2,
It can realize the whole process of clutch fluted disc is driven from figure 5 it can be seen that driving lever 6 only needs to rotate less angle [alpha], its
In, angle [alpha] refers to the angle for driving driving lever 6 needed for clutch tooth disk axial movement range to rotate；Period ring wedge shape is convex
Play plane 704 and ring support wedge-shaped protrusion plane 208 departs from, ring support wedge-shaped protrusion inclined-plane 201 and ring wedge-shaped protrusion
Screw is completed on inclined-plane 706, and then ring wedge-shaped protrusion plane 704 overlaps with ring chassis plane 207, under ring 7 is located at
Position, is separated with clutch axle sleeve 5, and clutch axle sleeve 5 can with the second fluted disc 4 under the effect of the reset force of self gravitation and clutch stage clip 26
By engagement, interior bucket is transmitted system with impeller and is fixedly connected, and clutch completes conversion of the washing to dehydration；The now stroke of ring 7
More than the stroke of clutch axle sleeve 5, abrasion between the two under high speed dewatering operating mode is avoided.
3. when being dehydrated completion：Driver is stopped, and driving lever 6 resets under the reset force effect of torsion spring 24, the band of driving lever 6
Dynamic ring 7 resets, and so as to drive clutch axle sleeve 5 to move up, departs from the second fluted disc 4, then enters with the first fluted disc 3 and engages, interior bucket
Locked, clutch returns to washing state；Clutch stage clip 26 is compressed simultaneously.
