Notes oil damper
Oil damper is put the silicon oil in the cylinder, but to choose this hardness of the oil is in proportion and the hardness of the spring to be used it is common.
For example, if you put the hard oil to a soft spring, soft spring will get a brief stretch, but it does not return easily to the oil is hard because of the original length.
Conversely, if you put a soft oil to a hard spring, so it becomes impossible to suppress is the repulsive force of the hard spring with a soft oil, it would end up followed by a band of spring.
A soft oil when spring from this kind of thing is soft, put the hard oil is the basic when spring is hard.
Without changing the oil, by changing the number and size of the hole of the oil damper piston, you can also adjust the hardness of the suspension.
Oil damper there are some caveats.
First most to the point that must be noted, the left and right of the damper is that certainly does not make sense to be aligned to the same hardness.
When the hardness of the left and right of the damper are not aligned, it will has a negative effect on the traveling.
Factors that are not available as the hardness of the damper, or have a different amount of air in the cylinder, will be considered, such as frictional resistance of the shaft and the O-ring is different.
The difference in hardness due to the amount of air the difference in the cylinder occurs in both expressions of a "diaphragm", "aeration expressions".
Diaphragm must pull out perfectly the air in the cylinder.
Speaking to the reverse is perfectly possible to align the hardness of the damper just pull out the air.
Aeration type are contaminated with air as bubbles in the oil, the bubbles when contracted the suspension is compressed.
It structures than the diaphragm-type is simple, but it can become difficult to align the amount of oil the inside of the bubble.
Oil damper is becoming need regular maintenance.
The cylinder case there is an O-ring so that it does not leak oil, but still will be oil gradually leaks from the shaft and O-ring gap.
When the course would decrease the amount of oil will vary the hardness of the damper so, you need to'll regularly replenished.
In addition, since the parts made of rubber, such as an O-ring and diaphragm will continue to deteriorate gradually, you will need to be replaced periodically.
Oil itself, since the deterioration due to stress and oxidation caused by expansion and contraction occurs, requires periodic replacement.
