Wherein: bucket, 17-impeller, 18-oil sealing, 19-dehydrating shaft, 20-rolling bearing, 21-projection, 22-hole, 23-projection, 24-hole, 25-groove in 1-braking tractor, 2-brake block, 3-brake ring, 4-clutch block, 5-back-moving spring, 6-driving wheel, 7-nut, 8-wash shaft, 9-bearing, 10-nut, 11-pressing plate, 12-clutch tractor, 13-bearing, 14-axle sleeve, the outer bucket of 15-, the 16-.
The specific embodiment
As shown in drawings.The clutch of electrical motor gearshift drums sleeved washer and brake apparatus comprise arrangement of clutch, transmission device, brake apparatus three parts.Clutch tractor 12 in the arrangement of clutch is fixed on the bottom of outer bucket 15, both ends of the surface have long projection 23 respectively, the clutch block 4 of short projection 21 is nested with rotationally on dehydrating shaft 19, and clutch tractor 12 contacts with the downside of clutch block by pressing plate 11.The driving wheel 6 that has hole 22 in the transmission device is fixed on the lower end of wash shaft 8 by key connecting and nut 7, impeller 17 in the upper end of wash shaft 8 connects in the bucket 16, the dehydrating shaft 19 of fixedlying connected with interior bucket movably are nested with on wash shaft by bearing 9 and are fixed on outer barrel by bearing 20, bearing 13 and axle sleeve 14; Be provided with oil sealing 18 between wash shaft and the dehydrating shaft and between dehydrating shaft and the axle sleeve 14.Braking tractor 1 in the brake apparatus is fixed on the opposite side of the bottom of outer bucket 15, and the brake block 2 on it combines when braking with brake ring, breaks away from during non-braking.The projection 23 that matches with the groove 25 of outer barrel bottom on the clutch block 4 links to each other with dehydrating shaft 19 by the hole on the brake ring 3 24, brake ring 3 is by nut 10 and packing ring location, clutch block can slide in the hole 24 at brake ring under the effect of clutch tractor, and can not relatively rotate; Be provided with back-moving spring 5 between brake ring and clutch block, projection 21 plugs together mutually with hole 22 on the driving wheel.Each operating mode of washing machine all has programme-control, and clutch tractor 12 all can be grasped at present technique field those of ordinary skill with the concrete structure of braking tractor 1.
Because the rigidity of outer bucket 15 bottoms is limited, for improving its rigidity, Tong bottom also can be fixed with stiffener outside, and this stiffener lower surface is provided with groove or the through hole that matches with clutch block upper end projection.Further, the braking tractor also can be fixed on the stiffener.
During washing, clutch tractor 12 is in shown position, this moment, the projection 23 of clutch block 4 was inserted in the groove 25 of outer bucket 15, make brake ring 3, dehydrating shaft 19 and 16 stalls of interior bucket, braking tractor 1 is not worked, brake block 2 is held tightly on brake ring 3, and driving wheel 6 drives wash shaft 8 and impeller 17 runnings, and washing machine carries out washing work.
During dehydration, 1 action of braking tractor drives brake block 2 and leaves brake ring 3,12 actions of clutch tractor, pressing plate 11 is moved to driving wheel 6 directions, the groove 25 of bucket 15 outside clutch block 4 leaves under the effect of back-moving spring 5, but be unable to do without the groove 24 of brake ring 3, projection 21 is inserted in the hole 22 at driving wheel 6 middle parts simultaneously, driving wheel 6, clutch block 4, brake ring 3, dehydrating shaft 19 and interior bucket 16 are held together, at this moment, bucket 16 and impeller 17 rotated together in driving wheel 6 drove, and washing machine carries out dehydration work.
During braking, braking tractor 1 at first is de-energized, and is reset under the pulling of spring, brake block 2 is held tightly and is made it with interior bucket 16 brakings on brake ring 3, after delay a period of time, and 16 stalls of interior bucket, 12 actions of clutch tractor recover the washing state in the groove 25 of bucket 15 outside clutch block 4 inserts.
When dehydration,,, guaranteed user's safety when outage because braking tractor 1 can automatically reset and brake if unusual conditions such as outage appear suddenly in washing machine; Clutch tractor 12 can not automatically reset when power down, and the interior bucket 16 that rotates at a high speed when making brake can not contact with the groove 25 of outer bucket 15 with clutch block 4, has guaranteed washing machine self structure safety.
For making clutch block 4 parallel moving up and down, described pressing plate 11 can also have round with clutch block 4 endoporus central through hole of the same size for the center, and corresponding clutch block lower end projection is provided with size and is a bit larger tham the projection of lower end projection 21 sizes and passes through the hole; Be provided with movable hinge joint fulcrum in a side away from clutch tractor 12; On direction, be arranged with the draining draught link anchorage and reach the contact pin that contacts with clutch piece downside perpendicular to hinge joint fulcrum and the round line of centres.Like this when clutch tractor 12 action, pressing plate 11 is moved by setpoint distance up and down around fulcrum, promote by contact pin that clutch block is parallel to move up and down, the pull bar of draining simultaneously is by setting the same moved further of stroke, with control washing or dehydration supervisor.
