Torque Converters
How does a Comet torque converter work? The drive clutch is activated by centrifugal force from the engine crankshaft. The moveable sheave of the clutch is forced in as the RPM of the engine is increased. This contacts the drive belt. The drive belt will then be forced to a larger diamter within the clutch sheaves, thus pulling it to a smaller diameter within the driven unit sheaves. The moveable sheave of the driven unit is forced out, allowing the belt to seek its smaller, high speed ratio diameter. As this happens, the speed from the engine transferred to the final drive is increased.
Model 20 Series (Symmetrical)
The model 20 uses a 3/4" top width belt. The belt mass lends substantially
to the driving ability of the system especially in cases where added
torque ability is required without danger of slipping the belt. The
belt mass of 3/4" top width is especially helpful in applications
of low speed, added power requirements such as tractor mowers, off road
dune buggies, mini bikes, ATV's, and go-karts. This is a conventional
type system featuring 13° angle sheave faces for a 26° collective
angle. Driven units available with either 6" or 7" diameter
sheaves.
Model 340 Series
Comet Torque Converters for All Engines thru 8 HP. The model 340 automatic
torque converter system was designed specifically for light horsepower
applications such as mini bikes and lightweight sports vehicles and
industrial equipment. Generally, engine driven, this converter is torque
sensitive, which the vehicle or driven load has influence on establishing
the ratio between the driver and driven. In normal operation, the driver
"shifts into high" in response to the engine's increase in speed; the
driven follows this speed change as in any variable pitch belt drive.
In the torque sensitive design, a cam actuator in the driven reacts
to increased torque demands by downshifting without loss of engine RPM.
In this way, the engine continues to operate at peak power range for
all but the most sever loads when it will shift into peak torque range.
Model 30 Series (Asymmetrical)
The model 30 uses a 3/4" top width belt. The belt mass in No. 30
is desirable in applications requiring extra rugged driving ability,
such as dune buggies, go-karts, mini bikes, ATV's, grounds maintenance
equipment, materials handling devices and industrial equipment. The
Model 30 series is mounted with both stationary sheaves inboard. Mounting
can be on a flat, fixed plane, requiring only minimum displacement.
TAV2 Torq-A-Verter
This is an asymmetrical type torque converter system which means the
sheave faces are non-symmetrical. They have different angles. In this
case, the moveable sheave face is 18" while the stationary sheave
face is 2-1/2" for a collective angle of 20-1/2". Here are
some reasons for selecting the asymmetrical concept. The Torque-A-Verter
can attain an .90:1 or 10% overdrive.
Model 40 Series
The model 40 is sometimes referred to as the "Mid-Range" torque converter
systems since it falls into the middle range between the Comet series.
The model 40 is a rugged piece of machinery. The drive clutch is composed
of heavy walled stamped steel to withstand the extreme rigors of rough
applications. Whenever there is a need, want and use for a torque sensitive
drive system device that is infinitely variable form engagement to the
highest speeds attainable (within the pitch diameter range), the 40
model system should be considered.
Model 44 CV "Magnum" Series (Symmetrical)
The Magnum 44 continuously variable transmission torque converter system
for up to 18 HP applications is a rugged piece of machinery. The drive
clutch is designed to withstand the extreme rigors of rough applications.
The driven unit is of the same quality construction as the drive clutch.
Application possibilities cover a wide range. By changing pucks and
spring, you can convert the Magnum from the standard 4 cycle setup to
be used on 2 cycle engines.
Model 500 Series
The model 500 drive and driven variable pulleys are installed in a power
train drive system to better match output requirements with an engine
output. If the engine is allowed to run at its peak output power, the
most power available from the engine will be directed to the driven
shaft. The model 500 responds to load requirements and changes the ratio
between the drive and driven pulleys so that the engine can maintain
its peak power output.
Model 94C Duster Clutch Series
This is the one to use for all V-twins and high torque applications!
With a beefy 1-3/16" belt, the 94C has the rugged reliability needed
when you want to spend your time riding, not making repairs. A 3.49-1
low and a .78-1 high provides a wide gear range for great low end pulling
power without sacrificing top speed! Custom calibration of drive unit
is quick and easy allowing you to get maximum performance out of your
engine.
Model 102EXP Series
Designed for snowmobiles and other applications that require a full range of exceptional ability from engagement through the highest speeds available from the power source, the 102C clutch is one of the best for snowmobiles and other machines using belt driven torque converters. The 102C clutch has unsurpassed tuning ability, outperforms clutches of similar design, has an open face design for economical servicing. Contact Comet Industries for
recommendations.
Model 108EXP Series
Designed for snowmobiles and other applications that require a full range of exceptional ability from engagement through the highest speeds available from the power source, the 108EXP clutch is one of the best for snowmobiles and other machines using belt driven torque converters. The 108EXP clutch has unsurpassed tuning ability, outperforms clutches of similar design, has an open face design for economical servicing.Contact Comet Industries for
recommendations.
4 Pro Series
The super clutch! The 108 4-Pro utilizes four clutch weights rather than three, greatly enhancing tuneability. Arms can be used in sets of two, allowing you to zero in on the amount of weight desired, and a captivated tower allows the shouldered cover bolts to virtually eliminate tower spreading. A fourth load bearing member increases the roller and button life. New moveable sheave busing, higher heat and wear resistance also extends the clutch performance.
