■Friction plate is the clutch disc made of the material which has excellent heat resistance and durability.
This clutch disc is made of compound and paper KV.
As a result, the connection is soft, and when you stand up under power and acceleration, it has an excellent performance that can be received firmly, and has the performance that can convey the road conditions to the rider linearly.
Its performance has been highly evaluated not only in road racing but also in off-road racing scenes such as motocross (even on sand) where grip and control performance such as response to the accelerator (sliding of the rear wheel) are required.
■The durability performance is about 3 to 5 times longer than that of conventional products.
■For the kits with pressure plates and hubs, ADVANTAGE uses Kashima coating for high durability, and ACC (Advantage Cool Coating) to lower the oil temperature for more race-oriented products.This prevents galling and wear caused by stepping.
The friction of the housing and hub is smoother and helps to prevent judder.
■When making a kit of the clutch itself, ADVANTAGE always redesigns the advantage based on the actual vehicle and the numerical data on the drawing, and review whether there is anything that can be done, whether the content volume (volume) is satisfied, and whether the allowable amount of friction and plate is the same.
The latest kits have increased capacity without compromising durability, and Advantage have also developed the "Plus 1" kit to accommodate higher performance vehicles.
The number of friction plates is increased by one compared to the stock one, which greatly improves the durability.
■The steel plate is very important and the clutch can slip with a little gap management.
The inside of the engine is naturally exposed to high temperature, and the plate warps due to heat distortion, and the gap between the friction plate and the plate is formed by the warp, and the clutch slips, and the touch and connection when releasing the clutch become bad.
The plate wear is a problem, but warping due to heat distortion is a bigger problem.
If there are 6 or 7 plates per vehicle, the slight distortion will be large and may reach several millimeters, while the work is completed within a few millimeters stroke.
A few millimeters in the clutch case, especially in the clutch system, is an unbelievable number.
Therefore, by applying GSN (special gas nitriding treatment) to the steel plate, ADVANTAGE succeeded in making it highly durable and having extra strength against distortion.
The surface of the steel plate has a lot of dimples called "knurling", but this is not for improving the oil removal, but for removing the distortion of the plate surface. Nowadays, however, the accuracy of the material itself is so high that it is no longer necessary to take measures against distortion, but it is still an advantage of the old days.
■The clutch springs are manufactured at KYB / SHOWA's factory specializing in suspension springs.
It is important to note that in the world of clutch springs and clutches, there have been a lot of products that seem to be too complicated.
This is partly due to the fact that springs themselves have high tolerance values when they are manufactured.
Advantage has developed a clutch spring using valve spring material (SWOSC-V) in a factory specializing in suspension springs, based on our long experience in suspension development.
The spring material SWOSC-V is used, and the inclination difference of the spring is less than 0.5 degrees, and the special shot peening processing is done, and the clutch of a stock motorcycle is reexamined and redesigned.
The spring rate is designed to be reduced by oil temperature.
■For the spring spring rate, ADVANTAGE has fundamentally overcome the situation where the clutch is just hard and heavy, which is often the case with reinforced clutches.
It eliminates the need to increase the spring rate so drastically in synergy with the friction and plate.(In some models, clutch slippage is suppressed by the spring rate)
This model tends to be heavy, but it is lighter than the rival products.
■Spring material SWOSC-V is used.This is a valve spring material.
This material is used where the performance cannot be compromised in an environment that is far more severe than that of a clutch.
The most notable thing is that the wire diameter (piano wire) differs in every tenth of a second depending on the models and the specifications, so there are few spring manufacturers who have the material in a timely manner, but suspension specialist manufacturers do not.
ADVANTAGE has enough wire diameters to cover most of the requirements and can produce products with wire diameters according to the design, resulting in high-performance and long-life products.
■Friction Disc Method "Segment Method" is the original method developed by F.C.C.
This is a production system that has brought about a dramatic evolution in the efficiency and quality improvement of clutch production, and realizes a significant improvement in the efficiency of the process by crimping the tape friction material to the core plate.
In addition, the high degree of freedom in the shape of the oil groove brought about by the characteristics of the manufacturing method enables flexible response to the various requirements of the product.
There are various performance requirements for clutches as a product, such as improvement of shock (ride comfort) when shifting gears by improving friction performance, and improvement of fuel efficiency by reducing drag (friction reduction) in the clutch off state.
Segmented discs can flexibly respond to these requirements by realizing highly flexible oil groove shapes.
