Single cylinder pressure shock absorber
Just as its name implies is to single tube (tube) body design,
internal into high pressure nitrogen stored in the body of the bottom of
chamber to free piston separation of oil and gas. This type of shock
absorber react fast, simple structure, thermal easy and convenient
maintenance.
Single tube (tube) type shock absorber in the back stretch long
stroke and compression stroke all rely on piston body produce dampingbrake racing,
and the gas chamber in the lower body, in order to free piston
separation oil and steam body (oil, gas separated), in the elongation
stroke, the piston chamber pressure, oil by the body to the compression
chamber is on the contrary, seal in gas indoor nitrogen in shortened,
become a negative pressure on the piston chamber of high enough value.
In the oil is not full flow to the chamber, the chamber offset
the uneven pressure type, therefore the shock will have good Q degree
performance, in addition the air chamber and hydraulic oil chamber is
completely separated, in under the condition of high pressure, won't
have a hole, so the phenomenon in the use of harsh circumstances, still
can produce a high level of stability, another oil seal for actuator
force on the piston to directly in the chamber pressure, require a high
degree of pressure and must pay special attention to the need for its
machining high-precision delicate degree, the general shock absorber
manufacturers to produce durability and high stability of single tube
(tube) type shock absorber.
And single cylinder on the contrary, the compound drum
manufacturing cost is low, to production, and the sealed gas belongs to
low pressure gas, and high pressure of single cylinder, piston actuator
compared when feeling more soft, this makes handling not as single tube
(tube) type have sensitive, this type of shock chamber into the nitrogen
not as single cylinder is so high, the bottom of the tube open
connected to the piston chamber and the gas chamber even path.
Piston internal mechanism basically and single type the same, the
difference is that in the shortened, the chamber part of the oil into
the chamber, the connected path be resistance, inner guide core upside
sets check valve in the elongation trip, from bar and top table between
leakage oil back to the gas chamber, in shortened they were not suction
gas indoor gas, its disadvantages for shock absorber in the elongation
stroke, the piston down chamber from the oil chamber suction pressure
value of the shock absorber oil easy generation vortex vacuum, and
dissolve in oil have a bubble.
The system is actually based on modified shock absorber, are
divided into 2 sets of hydraulic line. 2 sets of systems are the four
respectively the shock "tie" up, its working principle is four this is
independent of the shock absorber become a whole.
