The explanation of two-spring shock absorption and single-spring shock absorption is as follows:
Double-spring shock absorber refers to two cylinders inside and outside the shock absorber, the piston moves in the inner cylinder, due to the entry and withdrawal of the piston rod, the volume of the oil in the inner cylinder increases and shrinks, so the balance of the oil in the inner cylinder must be maintained by exchanging with the outer cylinder.
Single-spring shock absorber is a one-way acting shock absorber equipped with a floating piston in the lower part of the cylinder, (the so-called floating means that there is no piston rod to control its movement), forming a closed air chamber under the floating piston, filled with high pressure nitrogen.
2. Different structures
The double spring shock absorber is a two-way acting shock absorber with two inner and outer cylinders.
Single spring shock absorber is a one-way acting shock absorber with only one cylinder.
