Speed Queen top loader operation

[kalanikaau1]

In my never ending quest for information, can someone explain the particulars in a Speed Queen top load washers mechanical operation, or provide a link as to how it works?
I am somewhat versed in how a Maytag works, as in reversing motor rotation, does SQ do the same?
I'm intrigued by the helix unit on the underside, as well as well as what appears to be a diaphragm type clutch unit as well.

Helix unit? Diaphragm type clutch? What?

The machine does not have a clutch.

It's a simple transmission with a typical 2 speed induction motor.
Reversing polarity reverses run direction (simplified).
On direction is washing, going through the main transmission.
The other direction basically bypasses the actual transmission part of the transmission and more or less drives the tub directly.

On spin, all slipping is done by the belt - the belt basically acts like a clutch.

There is no helix spring for the reversing, spinning, agitating action of a Speed Queen. It has a cam below the main drive fully on the bottom of the transmission that releases the break when cranked in the spin direction allows the entire transmission and basket to spin, it’s very simple system design.

Some brands did use a helix spring in the transmission like Frigidaires WCI and GE filter flows generally that was a less durable design because the helix springs would break eventually.

This was also the beauty of the Maytag dependable care system. It eliminated the helix spring that could break.

Mahalo...

for your response, I only mentioned the term "helix" because that is what the SQ parts manual refers to it as, item # 11 in the attached images.
I also referred to item # 2 as a "clutch" device because it resembles a diaphragm type clutch used in vehicles, SQ refers to it as a "brake kit".

Indeed, the design is very simple in design as has proven to be very reliable, am I correct in assuming that my uber reliable 24 year old Maytag top loader, model # LAT2500AAE, uses the same technology, shown here as well?

This Maytag will be replaced with the SQ washer I am presently rebuilding, I hate to see it go, however it's developed a rubbing/grinding noise when agitating and it's outer was tub has developed multiple pinholes due to rust.

A brake is a brake, a clutch is a clutch - same as in a car.
The brake in this case is needed to slow the tub down if the lid is opened while spinning - some safety regulation.

That helix part appears to be a kind of one way slip - preventing from something from turning in the wrong direction.

The Maytag you mentioned has a clearly defined clutch in its parts list, but appears to use it's brake to provide slippage/ clutch functionality?
Not sure exactly what slips there under which circumstances, but that's more like a clutch for sure.

Yes, I am well aware of the 2 different components, however both function on one principle...friction.

You questioned me, rather condescendingly, about a helix unit, the diagram clearly calls it out as such.

Furthermore, if you were to read my original post, I stated that the there APPEARS to be a device which looks like a diaphragm type clutch, I corrected myself in referring it to a brake, as SQ clearly refers to.

Do have a good life, Sir.

Hi Hennik The Maytag washer uses a slipping belt for the clutch. Also there is no clutch in the Maytag washer.

The Speed Queen uses a cam much the same way that He Will Dr., Maytag does to release the pressure on the brake so the machine can spin when the motor reverses.

You should stick to things that you know about this is why I never comment about European machines that I’m not familiar with.
