HiT Clutch Mechanism
The Uniqueness of HiT Clutch
Compared to the clutches we commonly see on the market, Dr.Pulley HiT Clutch contains more components and is more complicated in terms of structure. For easier understanding, we simplified the structure in the figures below.
So, there are mainly three portions of the whole clutch, including:
- Base 1 －HiT Special.
- Base 2 －Function as traditional clutch.
- Pillow Spring －Bridge, only in HiT Clutch.
You may see several designs of HiT clutches, including various types of Dry clutches and Wet clutches. Even though they are not completely the same in terms of the mechanism, the principle behind the design is the same.
Base 1
Base 1 is one of the parts that specially created for HiT Clutch; that is, you will not see this part in other clutches on the market.
Among the parts onto Base 1, Push Pins play a critical role, accounting for the transportation and transmission of force in the system. When the engine works, Base 1 is the first to be driven.
Base 2
Base 2 contains Clutch Weights and Clutch Springs.
Clutch Weight is the one to touch (connect to, or grab) the clutch bell when driven by the centrifugal force;
Clutch Spring is the one that controls the timing Clutch Weight activates. Yep, you are right. It is basically the conventional clutch we know.
Base 1 + Base 2
Now we are going to combine Base 1 and Base 2. For easier understanding, we color Base 1 red and Base 2 blue.
Base 1 can rotate freely in a certain range (*the range appeals wider here for easy understanding);
When Base 1 rotates to the extent that Push Pins touch Clutch Weights, a force is therefore generated.
Pillow Spring
Pillow Spring is one of the most crucial parts of HiT Clutch. There will be 2 to 4 Pillow Springs in a HiT clutch, located between Base 1 and Base 2.
Once the engine starts, the force is transited from Base 1, through Pillow Springs, and then to Base 2. Therefore we can see Pillow Springs as a bridge.
Moreover, given it’s a spring, we can adjust its strength so as to manipulate the timing that Push Pins touch the Clutch Weights.
The stronger Pillow Springs are, the later Push Pins activate
On the contrary, the weaker Pillow Springs are, the earlier Push Pins activate.
