Machining process starts from outer side. And in the next, a machine grasps a flywheel and never releases it until finish.
At least the innovative time for Miata clutch system has come.
It is well known that ATS Inc takes the initiative in carbon parts for motor
sports in the world.
This time carbon clutch system and metal clutch system both for Miata become
available by Maruha and ATS joint.
This new line-up for Maita clutch is epoch-making invention.
The general clutch tuning is genuine cover and disk with the light weight-flywheel. This situation is same as Japan and USA. But this system is not enough performance for racers want more aggressive attack.
Maruha Power Clutch System has very unique performance. It is very easy to
operate for everybody with light-pedal foot, with easy clutch meeting like
stocks. And that with very sharp shift change, and with enough long life.
All factors are in your hands to enjoy these systems.
The prices are also so reasonable, this is Maruha's challenge to the new market.
Adaptation: All Miata model
Maruha Power Clutch System / Carbon disk :
Maruha Power Clutch System / Metallic disk :
Options:
Center pilot bearing / Genuine parts
Release bearing / Genuine parts
*These two items are out of kits, please take them separately.
Flywheel / 3.7kg ：
Machining process starts from outer side. And in the next, a machine grasps a
flywheel and never releases it until finish.
One chucking, then machining face and back, drilled and taps, every machining
process is done at once.
Our unique machining method is possible by the special machine for flywheels,
that high-level precision process is so much uniformity, and unnecessary for any
balancing.
As for the strength, material is carbon steel with thermal heat disposal at the final process, and can keep the very strength.
In spite of light weight in fact, there are no holes to reduce weight !!.
This is one of the features of Maruha Flywheel.
A pilot bearing to be inserted into the center of a flywheel.
This pilot bearing sometimes outs from a flywheel by strong vibration in races.
Maruha clutch system can prevent this phenomenon by a steel plate, and make a
pilot stable to keep a main shaft of a transmission.
Metallic clutch ：
OD 9" ( 230mm ), this is the largest size in Miata market
Dicks are tried for being lightweight even if it is only 0.1mm thinner, this
effort make performance that reduce inertia,
be possible very fast and smooth
shifting, sharp pick up.
When comparing Maruha disc with other companies' products.
You find how much
discs are so weigh by others. And it means how much Maruha disk is light.
Maruha disc is only 800g weigh, this lightweight can help synchronizers, bring
the accurate shift changing at high rpm.
Furthermore, to get the sharpness, our disc has so severe flat processing to be products.
Though it is the largest OD size, control friction materials to make clutch
meet more easy.
And provide high performance for torque transmitting, endurance
and easy operation than usual metallic discs.
Carbon clutch ：
OD 9" ( 230mm ), this is the largest size in Miata market
A melting point of carbon is higher than other material for clutch, The
difference is over 1,000 centigrade.
Carbon has very tough endurance against heat.
The specific gravity is 1.7, weight is about half of titanium.
Thermal expansion is 1/10 of steel, this is suitable material for clutch.
Maruha Power Clutch has a special carbon disc, this disc has so many carbon
fibers flowing any directions of 3D.
Usually a carbon fiber is cross like beautiful cloth, but our disc is completely
NOT like crossed appearance.
This proves that Maruha carbon disc is extremely
strength.
Three faces to meet is for a purpose to reduce weight. Carbon material has so
big capacity to transmit torque, so only three faces is enough.
The effect of lightweight is very big, only 500g super light disc is very tender
for synchronizers and vibrations in a transmission,
and can contribute quicker
shifts.
Carbon has a good endurance ability, you can use it for a long time.
This is
a verify feature of carbon clutch system.
Even if you give the hi-heat by hard driving, carbon seldom be deformed and
can keep flat form.
Carbon disc also has a performance of wide range at clutch meet. Every body can
control it easily.
The most distinguished point is price. Yes. Carbon material was very
expensive.
But now we can supply our carbon clutch system with reasonable price for Miata
owners.
We are proud of this price which many Miata owners can take them.
Clutch cover：
To realize a pressure cover with lightweight and compact size, we adapt a
forged aluminum and integrated body with cover and pressure plate.
And to get silence like stocks, connects pressure plates and cover by 15pcs
steel spring plates. When you foot a clutch pedal, never hear judder like usual
racing clutch by others.
These consisted parts are fixed by bolts, it is possible to replace each part and modify pressure power by exchanging spring plates.
Maruha Power Clutch system is set as 1,000kg a pressure cover.
Please do not hesitate it, in our system 1,000kg is not heavy, but very light
like a stock clutch. It is very easy control as for women by a devise of a
pressure cover.
This high performance like a magic is our crafts and skill.
Compatible Metallic and Carbon disc：
From a reason that both systems include a common flywheel and pressure cover, it
is possible to change dick from each others with exchanging some parts.
After service：
We are stocking all parts for replacements and delight our customers enjoy our
products for long time.
