One, when the washing operating mode, need brake band firmly be held tightly by braked wheel, wish that braking moment is bigger, if braking moment is not enough, the situation of bucket " transfer " in can often taking place during washing, bucket is except that normal left-right rotation promptly, whenever make a round trip, be to angle of free direction additional rotation of unilateral bearing, it is caused that this is that braked wheel skids, not only increase the wearing and tearing of brake band, and have a strong impact on clean result.
Two, when dehydration condition finishes or opens washing machine top case suddenly, need brake band effectively be braked in official hour by braked wheel, in fact because the outage of brake lever tractor makes the unexpected return of brake lever, tend to make braking time too short, brake too quickly, excessive as braking moment, the phenomenon of " hitting bucket " will take place, promptly interior bucket vibration is excessive, collide the washing machine shell inwall together with outer bucket, this is a kind of unsafe factor that should strict be avoided.
Above-mentioned two kinds of operating modes are mutual contradiction to the requirement of braking moment.The structure of existing brake band, its braking moment is difficult to be adjusted to neither " transfer ", again not the perfect condition of " hitting bucket ".
Existing belt braking belongs to the one-way brake structure, can only brake to reinforcement by folk prescription, and the other direction braking effect is very poor, uses unilateral bearing so must adorn, to remedy the defective of other direction braking effect difference.
Summary of the invention:
